From 2008 to 2009, “herbivore men (sôshoku danshi or sôshoku-kei danshi in Japanese)” became a trendy, widely used term in Japanese. It flourished in all sorts of media, including TV, the Internet, newspapers and magazines, and could even occasionally be heard in everyday conversation. As it became more popular its original meaning was diversified, and people began to use it with a variety of different nuances. In December of 2009 it made the top ten list of nominees for the “Buzzword (...) of the Year” contest sponsored by U-CAN. By 2010 it had become a standard noun, and right now, in 2011, people do not seem particularly interested in it. Buzzwords have a short lifespan, so there is a high probability that it will soon fall out of use. The fact remains, however, that the appearance of this term has radically changed the way people look at young men. It can perhaps even be described as an epochal event in the history of the male gender in Japan. (shrink)

The main point of our hypothesis “coloration undermines camouflage” is that many color patterns in plants undermine the camouflage of invertebrate herbivores, especially insects, thus exposing them to predation and causing them to avoid plant organs with unsuitable coloration, to the benefit of the plants. This is a common case of “the enemy of my enemy is my friend” and a visual parallel of the chemical signals that plants emit to call wasps when attacked by caterpillars. Moreover, this is (...) also a common natural version of the well‐known case of industrial melanism, which illustrates the great importance of plant‐based camouflage for herbivorous insects and can serve as an independent test for our hypothesis. We claim that the enormous variations in coloration of leaves, petioles and stems as well as of flowers and fruits undermine the camouflage of invertebrate herbivores, especially insects. We assume that the same principle might operate in certain animal–parasite interactions. Our hypothesis, however, does not contrast or exclude other previous or future explanations of specific types of plant coloration. Traits such as coloration that have more than one type of benefit may be selected for by several agents and evolve more rapidly than ones with a single type of advantage.

We describe and analyse how large herbivores strongly diminished a woody vegetation, dominated by the unpalatable shrub Sambucus nigra L. and changed it into grassland. Density of woody species and cover of vegetation were measured in 1996, 2002 and 2012 in the grazed Oostvaardersplassen. In 2002 and 2012 we also measured density and cover in an ungrazed control site. In 2002 we measured intensity of browsing and bark loss of Sambucus shrubs in the grazed and control sites. In the (...) grazed site the density of Sambucus and Salix spp. declined significantly between 1996 and 2012, and large areas changed into grassland. In the control site the density of Sambucus increased significantly during this period, the density of Salix spp. did not change, and the vegetation consisted of a mixture of woody species and a field layer dominated by tall herbs. In 2002 and 2012 the percentages of dead Sambucus shrubs were significantly higher in the grazed site than in the control site. In 2002 the percentages of twigs browsed and ring barked stems of Sambucus shrubs were significantly higher in the grazed site than in the control site. Our results show that debarking caused mature Sambucus shrubs to die, but that heavy browsing may have helped this process. Our results also point to a significant neighbour effect on the break down of Sambucus, suggesting that Aggregational Resistance and Associational Palatability were both active. Essential conditions for the break down of this woody vegetation were the presence of large herbivores, the low ratio between the areas of summer and winter feeding habitats and the competition amongst herbivores. Browsing may have been responsible for seedling death, as seedlings were found only in the control site and not on the old and newly established grasslands in the grazed site. (shrink)

Recent evidence indicates that the presence of serine proteinase inhibitors in plant leaves can reduce predation by insects. Plants can now be transformed with proteinase inhibitor genes with strong promoters to express the inhibitor proteins in relatively high levels at specific times. Inhibitors having variable specificities against digestive proteinases of insects and pathogens can now be assessed for their possible role(s) in natural plant defense and for their potential usefulness in protecting crop plants against herbivores.

Based on his theory of animalrights, Regan concludes that humans are morallyobligated to consume a vegetarian or vegandiet. When it was pointed out to him that evena vegan diet results in the loss of manyanimals of the field, he said that while thatmay be true, we are still obligated to consumea vegetarian/vegan diet because in total itwould cause the least harm to animals (LeastHarm Principle, or LHP) as compared to currentagriculture. But is that conclusion valid? Isit possible that some other (...) agriculturalproduction alternatives may result in leastharm to animals? An examination of thisquestion shows that the LHP may actually bebetter served using food production systemsthat include both plant-based agriculture and aforage-ruminant-based agriculture as comparedto a strict plant-based (vegan) system. Perhapswe are morally obligated to consume a dietcontaining both plants and ruminant(particularly cattle) animal products. (shrink)

Carrion and dung odours of various flowers have traditionally been considered an adaptation for attracting the flies and beetles that pollinate them. While we accept the role of such odours in pollinator attraction, we propose that they may also have another, overlooked, anti‐herbivore defensive function. We suggest that such odours may deter mammalian herbivores, especially during the critical period of flowering. Carrion odour is a good predictor for two potential dangers to mammalian herbivores: (1) pathogenic microbes, (2) proximity (...) of carnivores. Similarly, dung odour predicts faeces‐contaminated habitats that present high risks of parasitism. These are two new types of repulsive olfactory aposematic mimicry by plants: (1) olfactory feigning of carcass (thanatosis), a well‐known behavioural defensive strategy in animals, (2) olfactory mimicry of faeces, which also has a defensive visual parallel in animals.

The defense of plants against herbivores and pathogens involves the participation of an enormous range of different metabolites, some of which act directly as defensive weapons against enemies (toxins or deterrents) and some of which act as components of the complex internal signaling network that insures that defense is timed to enemy attack. Recent work reveals a surprising trend: The same compounds may act as both weapons and signals of defense. For example, two groups of well‐studied defensive weapons, glucosinolates (...) and benzoxazinoids, trigger the accumulation of the protective polysaccharide callose as a barrier against aphids and pathogens. In the other direction, several hormones acting in defense signaling (and their precursors and products) exhibit activity as weapons against pathogens. Knowing which compounds are defensive weapons, which are defensive signals and which are both is vital for understanding the functioning of plant defense systems. (shrink)

Animals suffer harms not only in human captivity but in the wild as well. Some of these latter harms are due to humans, but many of them are not. Consider, for example, the harms of predation, i.e. of being hunted, killed, and eaten by other animals. Should we intervene in nature to prevent these harms? In this article, I consider two possible ways in which we might do so: (1) by herbivorising predators (i.e. genetically modify them so that their offspring (...) gradually evolve into herbivores) and (2) by painlessly killing predators. I argue that, among these options, painlessly killing predators would be preferable to herbivorising them. I then argue that painlessly killing predators, despite its costs to predators, might under certain circumstances be justifiable. (shrink)

Palaeontology developed as a field dependent upon comparison. Not only did reconstructing the fragmentary records of fossil organisms and placing them within taxonomic systems and evolutionary lineages require detailed anatomical comparisons with living and fossil animals, but the field also required thinking in terms of behavioural, biological and ecological analogies with modern organisms to understand how prehistoric animals lived and behaved. Yet palaeontological material often worked against making easy linkages, bringing a sense of mystery and doubt. This paper will look (...) at an animal whose study exemplified these problems: the Chalicothere. Increasingly recognized as a specific type from finds across North America and Eurasia from the early nineteenth century onwards, these prehistoric mammals showed short back legs terminating in pawed feet, long front limbs ending in sharp claws, a long flexible neck, and herbivorous grinding teeth. The Chalicothere became a significant organism within palaeontological studies, as the unexpected mix of characters made it a textbook example against the Cuvierian notion of “correlation of parts,” while explaining how the animal moved, fed and behaved became puzzling. However, rather than prevent comparisons, these actually led to comparative analogies becoming flexible and varied, with different forms of comparison being made with varying methods and degrees of confidence, and with the anatomy, movement and behaviour of giraffes, bears, horses, anteaters, primates and other organisms all serving at various points as potential models for different aspects of the animal. This paper will examine some of the attempts to reconstruct and define the Chalicotheres across a long timescale, using this to show how multiple comparisons and analogies could be deployed in a reconstructive and evolutionary science like palaeontology, and illustrate some of the limits and tensions in comparative methods, as they were used to reconstruct organisms which were thought to be incomparable to any modern animal.

It is argued that the question of whether or not one is required to be or become a strict vegetarian depends, not upon a rule or ideal that endorses vegetarianism on moral grounds, but rather upon whether one's own physical, biological nature is adapted to maintaining health and well-being on a vegetarian diet. Even if we accept the view that animals have rights, we still have no duty to make ourselves substantially worse off for the sake of other rights-holders. Moreover, (...) duties to others, such as fetuses and infants, may require one to consume meat or animal products. Seven classes of individuals who are not required to be or become vegetarians are identified and their examption is related to nutritional facts; these classes comprise most of the earth's population. The rule of vegetarianism defines a special or provisional duty rather than any general or universal rule, since its observance it based upon the biological capacities of individual humans whose genetic constitution and environment makes them suitably herbivorous. It is also argued that generalizing the vegetarian ideal as a social goal for all would be wrongful because it fails to consider the individual nutritional needs of humans at various stages of life, according to biological differences between the sexes, and because it would have the eugenic effect of limiting the adaptability of the human species. The appeal to the natural interests of omnivores will not justify any claim that humans may eat amounts of meat or animal products in excess of a reasonable safety margin since animals have rights-claims against us.

Two recent hypotheses have proposed that non‐green plant colouration evolved as a defence against herbivores, either as protective colouration promoting handicap signals indicating plant fitness or by undermining their crypsis. The handicap hypothesis posits a co‐evolutionary process between plants and herbivores, whereas the anti‐crypsis hypothesis suggests that an arms race between insects and plants is the evolutionary mechanism. Both explanations assume that insects are the evolutionary origin causing plants' colouration. Here, we propose a different hypothesis, termed the “Defence (...) Indication hypothesis”. This idea focuses on the multiple protective functions of anthocyanins and carotenoids as pigments, and suggests that plant colouration evolved primarily in response to various stressors. Because pigments and defensive compounds share a common biosynthesis, the production of pigments also provides elevated defensive strengths against herbivores, a process termed priming. In effect, the Defence Indication hypothesis predicts that pleiotropic effects of the pigments and, more generally, plants' shared defence responses, explain why insects might react to plant colouration.

Within many animal taxa there is a trend for the species of larger body size to eat food of lower caloric value. For example, most large extant lizards are herbivorous. Reasonable arguments based on energetic considerations are often invoked to explain this trend, yet, while these factors set limits to feasible body size, they do not in themselves mathematically produce optimum body sizes. A simple optimization model is developed here which considers food search, capture, and eating rates and the metabolic (...) cost of these activities for animals of different sizes. The optimization criterion is defined as the net caloric gain a consumer accrues per day. This model does produce an optimum intermediate body size which increases with food quality - not the reverse. This discrepancy is accounted for, however, because the model also predicts that body size should be even more sensitive to increases in food abundance. In nature, many poor quality foods are also relatively abundant foods, hence the consumers eating them may maximize their daily energetic profit by evolving a relatively large body size. Optimum consumer body size also decreases with increases in consumer metabolic rate and prey speed. (shrink)

Testing of candidate biological control agents to estimate their likely field host ranges in the area of release has been part of weed biological control for several decades, with evolving techniques and goals. Similar efforts have been made less often for parasitoids and predators being introduced for arthropod biological control. Here, we review both techniques of host range testing and social objectives of such screening. We ask whether agents introduced for arthropod biological control should be subjected to host range testing (...) before release, and if so, are methods used for estimating host ranges of herbivorous arthropods appropriate, or are different approaches needed. Current examples in which host range testing has been employed for arthropod biological control are reviewed. We conclude with recommendations concerning guiding principles about use of host range testing. We recommend modest expansion of host range testing for arthropod biological control for projects on continents. We recommend more extensive testing for projects of introduction onto islands. We note that introductions to islands could provide opportunities to gain experience in use of host range estimation for this class of organisms and to conduct post release evaluations of host ranges. We urge caution in efforts to mandate host range testing but simultaneously recommend consultation between biological control workers and insect conservationists. (shrink)

The greatest diversity of butterflies and their host plants occurs in tropical regions. Some groups of butterflies in the tropics exhibit monophagous feeding in the larval stage, exploiting only one family of plants; others are polyphagous, feeding on plants in two or more distinct families. The two major types of tropical habitats for butterflies, namely primary and secondary forests, offer very different evolutionary opportunities for the exploitation of plants as larval food. Butterflies are faced with the major logistical problem, as (...) are many other herbivorous insects, of depositing eggs on the correct plant for successful larval feeding. This paper, using the concepts of phenotype set and spatial patchiness of resources, attemps to make some predictions as to the optimal phenotypic systems for monophagous and polyphagous feeding in tropical butterflies, as related to the spatial patchiness of larval host plants in primary and secondary forests. In addition to the secondary compound chemistry of larval host plants as playing a role in the evolution of monophagy and polyphagy, the assumption is made that the spatial patchiness of host plants within and among different families also acts as a major factor in determining optimal ranges of phenotypes for different patterns of larval feeding. Owing to the high spatial patchiness of primary forest species of canopy trees and vines, it is predicted that butterflies exploiting these will be mostly polyphagous, whereas secondary forests having stable formations of fewer plant species and larger patches of these plants, will have mostly monophagous species. Forest understories may have both monophagous and polyphagous species, depending upon the layer of forest and the general type of understory (i.e. palmaceous or dicotyledonous). Field data on some groups of butterflies from tropical America support these predictions. Polyphagous butterflies are predicted to possess a genetic system of mixed morphs with a population being polymorphic as a whole; monophagous butterflies are predicted to have individuals all more or less similar genetically, and with a high amount of genic variation within individuals. Other forms of monophagy may evolve in species that are essentially monomorphic but with various mechanisms (physiological, developmental, behavioral) of phenotypic flexibility at the individual level. Although the environment is essentially coarse-grained for larvae since most are sedentary and polymorphism is an optimal adaptive strategy, the oviposition strategy of the adult must also be considered and some situations (i.e. forest canopy) have resources (host plants) distributed in a fine-grained fashion. Other forms of limited polyphagy may result from monomorphic genetic systems in which there is considerable phenotypic flexibility. (shrink)

Pleistocene Park is a large-scale science experiment in Arctic Siberia in the form of a future-oriented rewilding project with the goal of mitigating climate change. The park’s creators hypothesize that introducing large herbivores into the area will slow the thawing of permafrost. Using the approach of multispecies ethnography in attending to the nonhuman agencies at work in the project, I argue that the park differs from other rewilding projects, which are usually ecocentric, in emerging as a survivalist project with (...) a distinct anthropocentric bent. Even so, the park’s survivalist goal for humans coexists with ontologies based on collaboration and mutual aid between humans and nonhumans and between organic and inorganic matter, with extensive agency assigned to nonhuman others. Drawing on ethnographic fieldwork within the frame of the park’s various genealogies, I trace the project’s underlying assumptions in equal measure to the history of Russian science and to the park’s lead scientists’ experience of sociopolitical rupture following the collapse of the Soviet Union. As a case study, Pleistocene Park is especially suited to exploring issues of time and temporality, apocalypticism and redemption, and extinction and eternity, in addition to particular visions of the natural and the human.

With the turning of wilderness areas into wildlife parks and the returning of developed areas of land to the forces of nature, intermediate hybrid realms surface in which wild and managed nature become increasingly entangled. A partitioning of environmental philosophy into ecoethics and animal welfare ethics leaves these mixed territories relatively uncharted—the first dealing with wild (animals), the second with the welfare of captive or domestic animals. In this article, we explore an environmental philosophy that considers explicitly these mixed situations. (...) We examine a recent Dutch policy of introducing domesticated and semi-wild large herbivores in newly developed nature areas. Larger issues are at stake, such as the intertwinement of nature and culture, the dynamic character of de-domestication processes, and the relation between concepts of authenticity and the wild. We sketch a pluralistic, dynamic, and pragmatic environmental philosophy that is capable of dealing with the complicated ethicalproblems concerning creatures and land caught between domestication and the wild.

The theme ‘East versus west’ is an old topic for discussion, but one that is constantly being rehashed. Though it has many aspects, a number of elements remain vague. Do East and West each form a monolithic bloc? Where does the East begin in the West's eyes, and vice versa, the West for the East? What, if any, are the basic differences separating the two?Palaeontologists tell us that a dividing line indicating a divergence of traditions in stone tools can be (...) traced back to the Lower Palaeolithic era, that is, a million years ago, in the western region of India. To the east of that line, in other words in East and South-east Asia, the most common tools are choppers and chopping-tools, while to the west, in western Asia, Europe and Africa, the main tools are hand-axes. The former are suitable for working vegetable materials and making bamboo or wooden, therefore perishable, objects, which for this reason leave no trace in the form of archaeological clues. The hand-axes are capable of being worked into stylized shapes and are appropriate for dismembering large herbivores and cutting up their meat. (shrink)

To ensure their survival in natural habitats, plants must recognize and respond to a wide variety of insect herbivores. Aphids and other Hemiptera pose a particular challenge, because they cause relatively little direct tissue damage when inserting their slender stylets intercellularly to feed from the phloem sieve elements. Plant responses to this unusual feeding strategy almost certainly include recognition of aphid salivary components and the induction of phloem‐specific defenses. Due to the excellent genetic and genomic resources that are available (...) for Arabidopsis thaliana (Arabidopsis), this plant was chosen as a model system to study the metabolic and transcriptional responses to infestation by two aphids, Myzus persicae (green peach aphid, a broad generalist) and Brevicoryne brassicae (cabbage aphid, a crucifer‐feeding specialist). Future research on Arabidopsis–aphid interactions will lead to the identification of aphid‐specific elicitors, components of the defense‐signaling pathway, and additional metabolic responses that are induced by aphid infestation.

Analysis of a diverse cross‐sample of plant‐insect interactions suggests that the abundance of vitamin C (L‐ascorbic acid, ascorbate or AsA) in plants influences their susceptibility to insect feeding. These effects may be mediated by AsAs roles as an essential dietary nutrient, as an antioxidant in the insect midgut, or as a substrate for plant‐derived ascorbate oxidase, which can lead to generation of toxic reactive oxygen species. Ascorbate can also influence the efficacy of plant defenses such as myrosinases and tannins, and (...) alter insects' susceptibility to natural enemies. Conversely, herbivores appear to influence both de novo synthesis and redox cycling of AsA in their host plants, thereby potentially altering the nutritional value of crops and their susceptibility to pests. The recent development of genetically modified crops with enhanced AsA content provides both an impetus and a tool set for further studies on the role of AsA in plant‐insect interactions. (shrink)

Deciduous trees remobilize the nitrogen in senescing leaves during the process of autumn colouration, which in many species is associated with increased concentrations of anthocyanins. Archetti1 and Hamilton and Brown2 observed that autumn colouration is stronger in tree species facing a high diversity of specialist aphids. They proposed a coevolution theory that the bright colours in autumn might provide an honest signal of defence commitment, thus deterring migrant aphids from settling on the leaves. So far, there have been very few (...) experimental results to support the hypothesis, and tree commitment to phenolics‐based defences has not shown direct protection against aphids. Predators and parasitoids have been found to be the major controllers of arboreal aphids. Indirect defences involve the emission of attractive volatile compounds that enhance the effectiveness of carnivorous enemies. The indirect defence hypothesis is presented to explain low aphid diversity on tree species that are green during autumn. The hypothesis suggests that green foliage can continue to produce herbivore‐inducible plant volatiles and maintain volatile‐based indirect plant defences against aphids until leaf abscission.

Homo sapiens is a mammal of the order Primates. What most distinguishes primates from other mammals is their ability to cerebrate. Cerebration developed fastest among the Anthropoidea primates , and subsequently the hominids . The increase in brain mass only by Homo sapiens—and only over the past 10,000 years—possess superior Darwinian fitness: for the preceding 30 million years primates had played a rather marginal role in the world’s biological system.Homo sapiens’ success as the creator of developed civilization was possible only (...) thanks to his special adaptation capabilities, shaped by natural selection at the dawn of his existence.Primates first appeared in the Oligocene about 30 million years ago, and the first two-legged anthropoid, Australopithecus, about 6.5–5.7 million years ago. The transition from Australopithecus to the species we call Homo was in many ways an evolutionary milestone. Australopithecus was exclusively herbivorous and formed neither organized communities nor settlements. His successor, Homo erectus, on the other hand, possessed heretofore unknown skills like hunting and gathering, which considerably influenced both his lifestyle and his diet—he increasingly ate meat from cadavers or animals he had killed himself. Fossil remains of Homo erectus dating back two million years have been unearthed throughout Africa, China, Indonesia, Pakistan, the Middle East, and Europe.Homo sapiens derives from the rather small Homo erectus population in East Africa and has been the earth’s only hominid for a relatively short time about 10,000 years ago before he still shared his world with Neanderthal man and the diminutive Homo floresiensis.Despite racial differences there is surprisingly little variation in the human genome. We are all 99 percent genetically alike, moreover genome variations do not correlate to skin color.Homo sapiens’ hunter-gatherer lifestyle led him to seek solutions which today find application only in human communities. In time his biological capabilities were enriched by the skill of speech, this in turn helping to develop creativity, self-awareness, a sense of dignity, and group, ethnic and national loyalty, eventually leading to the emergence of religion as a path to life’s fundamental truths and an antidote to the everpresent fear of death.The Neolithic Revolution began about 10,000 years ago. Several thousand years later the evolution of farming and breeding led to the emergence of the first civilizations. The transition from hunting and gathering to agriculture changed radically not only economic and social structures but, as speech developed, helped form civilizations and cultures.Over the past 2000 years humanity has changed the global environment but has itself remained unchanged in heritability. The awareness that despite all racial, ethnic, cultural, or linguistic differences we belong to an exceptionally homogeneous species, can be an inspiration for humanity to strive towards a universal civilization in which all these differences could be contained.

Some data from earlier work concerning the evolutionary correlation of anthophilous insects, entomophilous plants, herbivorous animals, and natural soil groups are briefly summarized. Presumed successive evolution of plant and animal communities from the early Paleozoic era to the more recent formation of prairies, steppes and other grassland areas is described and pictured in Fig. 6. A definite correlation has been found among the coevolution of flowering plants, pollinating insects, ruminant animals and fertility grades of natural soil groups .Plants, insects, animals (...) and soil are interrelated in evolution as reciprocal selective and regulating factors in certain biotic and abiotic environments. This complex system can be better studied by application of the coenogenic concept and hologenic and syngenic methods.Various stages of the development of an agricultural environment in the prairie areas of the North American plains are briefly described and illustrated in Plates I–VII. A new radical change in the development by the introduction of so-called “Circle Farming” is pictured in Plates VIII–IX. This new irrigated farming system is not only profitable for the increasing of yields, but promises to some extent the restoration of a biologically balanced environment in an extensively cultivated agricultural landscape.

From a largely Western phenomenon, the “animal turn” has, in recent years, gone global. Animals and Human Society in Asia: Historical, Cultural and Ethical Perspectives is just such a timely product that testifies to this trend.But why Asia? The editors, in their very helpful overview essay, have from the outset justified the volume's focus on Asia and ensured that this is not simply a matter of lacuna filling. The reasons they set out include: the fact that Asia is the cradle (...) of early human settlement and animal domestication; Asia encompasses an extreme diversity of closely connected ecosystems and human cultures; Asia is the place where the world's major religions originated; and, as in other parts of the world, Asia's use of animals for food and other utilitarian purposes constitutes a prominent feature of its culture. All of these factors, they argue, made Asia a unique lab for the exploration of major developments in human civilization and the complexities of human-animal interactions.Based on these premises, the book is divided into four parts, each concentrating on areas that the editors consider to have paramount significance in world history: Part I, “Hunting and Domestication”; Part II “Animals as Food”; Part III “Animals at War”; and Part IV “Animals in Culture and Religion.” As many good works on animal studies do, the volume adopts a truly cross-disciplinary approach, uniting scholars from disciplines as diverse as archaeology, history, anthropology, art, religion, literature, and cultural studies. It too takes an interregional approach and covers a vast geographical area, stretching from the western edge of Asia in the Levant to Central Asia, where once roamed the horses of the nomadic pastoral tribes, to the other end of Asia, including India, China, and Japan. Temporally impressive as well, the work takes us from the deep history of the Paleolithic period up to the contemporary world, exploring the diverse roles that a wide range of animals—horses, donkeys, camels, elephants, tigers, and so forth—have played in Asia's rich and unique past and present.Strong in archaeology, Part I, “Hunting and Domestication,” responds to the much-called for “deep” or “coevolutionary” history of human-animal relations in recent years. The three chapters discuss, respectively, the roles that proboscideans have played in the diet and culture of early societies in Paleolithic China and beyond; the ways in which animals of all sizes have been increasingly integrated into the diet, daily uses, trade, and warfare in Holocene Negev; and the diversifying roles played by donkeys in the early Bronze Age in Southern Levant as a food source, a means of transport and in ritual sacrifices. Together, they demonstrate, with reference to telling archaeological evidence how the early societies in this region have been highly dependent upon the increasingly sophisticated interactions with and uses of mega-herbivores in the protracted and by no means clear-cut transition from hunting and herding towards the agricultural way of life, affirming the co-existing and co-constituting relations between humans and other animals in the deep past of Asia.The chapters in the section on “Animals at War” equally reveal the crucial roles that animals have played in the military sphere, as either a practical war technology or a show of military power. “Elephants in Mongol History” revisits the thesis of elephant-mounted troops in South and Southeast Asia as a barrier to Mongol expansion. Through its lively account of the pivotal battles in Mongolian history, especially that against India and China, it illustrates with great success the complex interactions between animals (especially elephants, horses, and humans), technology, and the geographical environment, which jointly exercised their influence on the outcome of warfare and degree of success of political rule. Turning away from the dynamic of warfare, the following two chapters explore the biopolitical question of the management of the horse as a bio-resource in the Mamluk Sultanate of Egypt and Syria (1250–1517) and early Ming Dynasty China, respectively. The first one places its focus on the breeding, procurement, and feeding of the horse subjects in question, while the latter concentrates on the human organization of various resources for the upkeep of government horses—a conventional area of study called “horse administration” in the institutional history of the government in China.The last section, “Animals in Culture and Religion,” examines the changing images of apex predators, such as lions and tigers, in Buddhist perceptions from South Asia to East Asia; the cult of the Horse King in late Imperial China; and the significance of animal signs in Mongolian historiography. They represent an established approach in animal studies that seeks to understand different aspects of human culture through symbolic or metaphorical animals. Instead of treating the animals discussed as mere abstractions, which has been a frequent criticism of works that adopt this approach, the relations between the symbolic animals and their prototype in the natural world were attentively explored. The essay on the cult of the Horse King, for example, closely links the wax and wane of the cult since late imperial China with the changing use and subsequent disuse of the actual horses in agriculture, transportation, commerce, and quotidian life. Yet, classic as these essays on symbolic animals are, one does feel slightly unsatiated when coming to the end of this section, which also marks the end of this volume. Having been reminded early in the introductory essay that Asia was “a major site for the emergence of moral teachings and ethical guidance on the treatment of animals” and how this legacy “still affects the lives of billions of humans to this very day,” one feels naturally rather let down that no article in this volume directly addresses this vital ethical dimension, especially since it belongs to a series on “animal ethics.”Indeed, regarding the task of placing either the nonhuman animals or the ethical relations between humans and other animals center stage, the essays in this volume achieve only varying levels of success. Some authors exhibit a more acute awareness of what “animal studies” or “animal ethics” might entail epistemically and methodically and experiment by paying closer attention to the species-specific characteristics, experience, and agency of nonhuman animals in order to cast off the deified anthropocentrism previously ruled in humanist scholarship. However, others have made no such attempt. For example, in Part II of “Animals as Food,” an essay on the production and consumption of milk in contemporary China, albeit alert to the issue of health hazards to consumers, omits any consideration of the subject from the dairy cows’ perspective under the modern intensive farming system. Moreover, otherwise superb research on the tuna-fishing industry in Japan, with its insightful discussion of the nexus between knowledge economies and imperial politics, too passes over any discussion of the fate of the tuna, whether collectively as a group of living organisms containing 15 species or individually as animals with an embodied experience. One does ponder whether these essays would fit better in a volume on the cultural history of food or on the entwining history of knowledge production, economics, and politics, which conventionally position human interests at the center of research.Taken as a whole, this is an impressive volume that directs our attention to the hitherto understudied world of Asia in animal studies. The long durée, with its interdisciplinary and interregional approach, also most powerfully presents a past in Asia that could not have been the same without the participation of animals at every level, from everyday life to the shaping of cultural values, the construction of belief systems, the building of a national identity, and even the rise and fall of regimes. Scholars and students interested in expanding the frontier of our understanding of the world with a more inclusive “we” should find a wealth of interesting subjects on which to build further research. Finally, the volume also presents a fitting occasion for all scholars committed to animal studies to consider the grave challenge confronting the field that arose alongside its growing respectability and rapid expansion: Should it be oriented toward the destabilization of our previously anthropocentric conception of the world? Or should no such perimeter be imposed, as in this volume? The overall breadth and limitations of this volume leave one pondering this issue. (shrink)

Most land plants associate with mycorrhizal fungi that can connect roots of neighboring plants in common mycelial networks (CMNs). Recent evidence shows that CMNs transfer warning signals of pathogen and aphid attack between plants. However, we do not know how defence‐related signaling via CMNs operates or how ubiquitous it is. Nor do we know what the ecological relevance and fitness consequences are, particularly from the perspective of the mycorrhizal fungus. Here, we focus on the potential fitness benefits for mycorrhizal fungi (...) and outline hypothetical scenarios in which signal transfer via CMNs is modulated in order to acquire the most benefit for the fungus (i.e. acquisition of carbon) for minimal cost. We speculate that the signal may be quantitative and may elicit plant defence responses on different levels depending on the distance the signal is transferred. Finally, we discuss the possibility of practical applications of this phenomenon for crop protection. (shrink)

This paper examines how the riparian vegetation of perennial and ephemeral rivers systems in the semi-arid, winter rainfall region of South Africa has changed over time. Using an environmental history approach we assess the extent of change in plant cover at 32 sites using repeat photographs that cover a time span of 36-113 years. The results indicate that in the majority of sites there has been a significant increase in cover of riparian vegetation in both the channel beds and adjacent (...) floodplain environments. The most important species to have increased in cover across the region is Acacia karroo. We interpret the findings in the context of historical changes in climate and land use practices. Damage to riparian vegetation caused by mega-herbivores probably ceased sometime during the early 19th century as did scouring events related to large floods that occurred at regular intervals from the 15th to early 20th centuries. Extensive cutting of riparian vegetation for charcoal and firewood has also declined over the last 150 years. Changes in the grazing history as well as increased abstraction and dam building along perennial rivers in the region also account for some of the changes observed in riparian vegetation during the second half of the 20th century. Predictions of climate change related to global warming anticipate increased drought events with the subsequent loss of species and habitats in the study area. The evidence presented here suggests that an awareness of the region's historical ecology should be considered more carefully in the modelling and formulation of future climate change predictions as well as in the understanding of climate change impacts over time frames of decades and centuries.
