In the last decade, research on the previously dormant field of camouflage has advanced rapidly, with numerous studies challenging traditional concepts, investigating previously untested theories and incorporating a greater appreciation of the visual and cognitive systems of the observer. Using studies of both real animals and artificial systems, this book synthesises the current state of play in camouflage research and understanding. It introduces the different types of camouflage and how they work, including background matching, disruptive coloration and obliterative shading. It also demonstrates the methodologies used to study them and discusses how camouflage relates to other subjects, particularly with regard to what it can tell us about visual perception. The mixture of primary research and reviews shows students and researchers where the field currently stands and where exciting and important problems remain to be solved, illustrating how the study of camouflage is likely to progress in the future.

From ancient cave paintings of honey bee nests to modern science's richly diversified investigation of honey bee biology and its applications, the human imagination has long been captivated by the mysterious and highly sophisticated behavior of this paragon among insect societies. In the first broad treatment of honey bee biology to appear in decades, Mark Winston provides rare access to the world of this extraordinary insect. In a bright and engaging style Winston probes the dynamics of the honey bee's social organization. He recreates for us the complex infrastructure of the nest, describes the highly specialized behavior of workers, queens, and drones, and examines in detail the remarkable ability of the honey bee colony to regulate its functions according to events within and outside the nest. Winston integrates into his discussion the results of recent studies, bringing into sharp focus topics of current bee research. These include the exquisite architecture of the nest and its relation to bee physiology; the intricate division of labor and the relevance of a temporal caste structure to efficient functioning of the colony; and, finally, the life-death struggles of swarming, supersedure, and mating that mark the reproductive cycle of the honey bee. "The Biology of the Honey Bee" not only reviews the basic aspects of social behavior, ecology, anatomy, physiology, and genetics, it also summarizes major controversies in contemporary honey bee research, such as the importance of kin recognition in the evolution of social behavior and the role of the well-known dance language in honey bee communication. Thorough, well-illustrated, and lucidly written, this book will for many years be a valuable resource for scholars, students, and beekeepers alike.

Metacommunity Ecology, Volume 59 (Hardcover): Mathew A Leibold, Jonathan M. Chase Metacommunity Ecology, Volume 59 (Hardcover)
Mathew A Leibold, Jonathan M. Chase
R1,148 R865 Discovery Miles 8 650 Save R283 (25%) Shipped within 7 - 12 working days

Metacommunity ecology links smaller-scale processes that have been the provenance of population and community ecology--such as birth-death processes, species interactions, selection, and stochasticity--with larger-scale issues such as dispersal and habitat heterogeneity. Until now, the field has focused on evaluating the relative importance of distinct processes, with niche-based environmental sorting on one side and neutral-based ecological drift and dispersal limitation on the other. This book moves beyond these artificial categorizations, showing how environmental sorting, dispersal, ecological drift, and other processes influence metacommunity structure simultaneously. Mathew Leibold and Jonathan Chase argue that the relative importance of these processes depends on the characteristics of the organisms, the strengths and types of their interactions, the degree of habitat heterogeneity, the rates of dispersal, and the scale at which the system is observed. Using this synthetic perspective, they explore metacommunity patterns in time and space, including patterns of coexistence, distribution, and diversity. Leibold and Chase demonstrate how these processes and patterns are altered by micro- and macroevolution, traits and phylogenetic relationships, and food web interactions. They then use this scale-explicit perspective to illustrate how metacommunity processes are essential for understanding macroecological and biogeographical patterns as well as ecosystem-level processes. Moving seamlessly across scales and subdisciplines, Metacommunity Ecology is an invaluable reference, one that offers a more integrated approach to ecological patterns and processes.

Orca - How We Came to Know and Love the Ocean's Greatest Predator (Hardcover): Jason M. Colby Orca - How We Came to Know and Love the Ocean's Greatest Predator (Hardcover)
Jason M. Colby
R479 R363 Discovery Miles 3 630 Save R116 (24%) Shipped within 7 - 12 working days

Orcas are the most profitable and controversial display animal in history, and since the release of the documentary Blackfish in 2013, millions around the world have focused on their plight. Yet no historical account has explored how we came to care about killer whales in the first place. In Orca, Jason Colby tells the exhilarating and often heartbreaking story of how people came to love the ocean's greatest predator. Historically reviled as dangerous pests, killer whales were dying by the hundreds, even thousands, by the 1950s-the victims of whalers, fishermen, and even the US military. In the Pacific Northwest, fishermen shot them, scientists harpooned them, and the Canadian government mounted a machine gun to eliminate them. But that all changed in 1965, when a Seattle entrepreneur named Ted Griffin became the first person to swim and perform with a captive killer whale. The show was a hit, and he began capturing and selling others, including Sea World's first "Shamu." Over the following decade, live display transformed popular and scientific views of Orcinus orca. The public embraced killer whales as charismatic and friendly while scientists enjoyed their first access to live orcas. In the Pacific Northwest, these captive encounters reshaped regional values and helped drive environmental activism, including Greenpeace's anti-whaling campaigns. Yet even as Northwesterners taught the world to love whales, they came to oppose their captivity. So when Sea World attempted to catch its own killer whales, Northwesterners would fight for the freedom of a marine predator that had become a regional icon. With access to previously unavailable documents and interviews, Colby offers the definitive history of how the feared and despised "killer" became the beloved "orca" and what that means for our relationship with the ocean and its creatures.

History of Terrestrial Mammals in South America - How South American Mammalian Fauna Changed from the Mesozoic to Recent Times... History of Terrestrial Mammals in South America - How South American Mammalian Fauna Changed from the Mesozoic to Recent Times (Hardcover, 1st ed. 2019)
Thomas Defler
R2,461 R2,336 Discovery Miles 23 360 Save R125 (5%) Shipped within 7 - 11 working days

This book takes a non-technical approach in covering the evolution of South American mammalian fauna throughout geological history, and discusses how South America has changed due to mammalian invasions. Unlike other works on the subject, this book attempts to answer several crucial questions that often go unmentioned together in one cohesive monograph. What was the fauna like before the American interchange? What were the origins of the now-extinct groups when northern species arrived and out-competed them? How did the modern mammalian fauna come into being with such disparate animal groups? This information is given from a historical perspective throughout the book's 15 chapters, and is presented in an easily graspable fashion by mostly avoiding technical language. The book is written for academics, scientists and scholars engaged in paleontology, zoology and evolutionary biology, but may also appeal to a larger audience of general readers interested in mammalian evolution. The book begins with an introduction, describing the tools necessary to interpret the evolutionary history of South American mammals in geological terms and some of the early people who helped found South American mammalian paleontology. Chapter 2 describes the Mesozoic first mammals of Gondwana and what we are learning about them, dominant before the K/T extinction event. Then chapters 3 through 8 cover the Cenozoic, or "Age of Mammals", highlighting the major mammalian groups of South America that replaced the earlier mammals of Gondwana. These groups include the marsupials, native ungulates, the xenarthrans (armadillos, anteaters, sloths), the caviomorphs (rodents), and the platyrrhine monkeys. Chapters 9 and 10 address the Antarctic La Meseta fossils and the Colombian La Venta fossil faunal assemblages. Chapter 11 discusses the neotropical mammals that invaded the Caribbean Islands, and illustrates the influence South America has had on adjacent faunas. Chapter 12 describes the origin of the Amazon River and the role it has played in the evolution of the mammals and other flora and fauna. Chapter 13 tells the story of the Great American Biotic Interchange (GABI), and chapter 14 follows this up with a discussion of the Pleistocene mammal communities and their eventual extinction. Chapter 15 concludes the text by discussing the modern mammals of South America, and how despite the extensive Pleistocene extinctions there is still a lot of mammalian diversity in South America.

Monkeytalk - Inside the Worlds and Minds of Primates (Hardcover): Julia Fischer Monkeytalk - Inside the Worlds and Minds of Primates (Hardcover)
Julia Fischer
R446 R421 Discovery Miles 4 210 Save R25 (6%) Shipped within 7 - 12 working days

Monkey see, monkey do or does he? Can the behavior of non-human primates their sociality, their intelligence, their communication really be chalked up to simple mimicry? Emphatically, absolutely: no. And as famed primatologist Julia Fischer reveals, the human bias inherent in this oft-uttered adage is our loss, for it is only through the study of our primate brethren that we may begin to understand ourselves. An eye-opening blend of storytelling, memoir, and science, Monkeytalk takes us into the field and the world's primate labs to investigate the intricacies of primate social mores through the lens of communication. After first detailing the social interactions of key species from her fieldwork from baby-wielding male Barbary macaques, who use infants as social accessories in a variety of interactions, to aggression among the chacma baboons of southern Africa and male-male tolerance among the Guinea baboons of Senegal Fischer explores the role of social living in the rise of primate intelligence and communication, ultimately asking what the ways in which other primates communicate can teach us about the evolution of human language. Funny and fascinating, Fischer's tale roams from a dinner in the field shared with lionesses to insights gleaned from Rico, a border collie with an astonishing vocabulary, but its message is clear: it is humans who are the evolutionary mimics. The primate heritage visible in our species is far more striking than the reverse, and it is the monkeys who deserve to be seen. "The social life of macaques and baboons is a magnificent opera," Fischer writes. "Allow me now to raise the curtain on it."

This volume provides a modern introduction to the soil fauna and their contributions to ecosystem function, the mechanisms that structure soil fauna assemblages from local to global scales, and the potential impacts of global change on soil fauna assemblages and through this ecosystem function. Wanting to be an accessible primer, this book is a high level overview of current knowledge rather than a detailed tome of all existing information, with emphasis being placed on key findings and general patterns. It focuses on the soil fauna but contextualizes these assemblages in relation to the microbial assemblages belowground and the vegetation aboveground. It is clear that our knowledge of soil fauna assemblages is ever increasing, but there is still a lot to discover. Key areas of research are highlighted, with particular reference to the future of soil fauna assemblages.

Dragonflies - Behavior and Ecology of Odonata (Hardcover): Philip S. Corbet Dragonflies - Behavior and Ecology of Odonata (Hardcover)
Philip S. Corbet
R3,163 Discovery Miles 31 630 Shipped within 7 - 11 working days

Among the most ancient and powerful of insects, dragonflies fascinate scientists and nonspecialists in part because they are large enough for the behavior of individual insects to be observed and interpreted. Indeed, so much useful information exists about dragonflies that they serve as valuable models for interpreting the behavior and ecology of other taxa. Philip S. Corbet has devoted a lifetime to their study. His book A Biology of Dragonflies has been a standard text for more than thirty-five years. This latest book establishes a new benchmark for the Odonata, providing a comprehensive, critical review of past and current knowledge both published and unpublished about species from all biogeographical regions in both functional and evolutionary contexts. The volume emphasizes the diversity found in dragonfly behavior as well as unifying patterns. It describes the behavioral strategies that influence the fitness of individuals in physical and biotic environments and in all stages of the life cycle, and identifies the biological principles reflected in those strategies. The book also examines behavior associated with processes such as habitat selection, foraging, seasonal regulation, migration, territoriality, mating, and sperm competition, emphasizing the interdependence of all developmental stages as well as relationships among dragonflies and other animals, including humans. Dragonflies represents a remarkably thorough and searching appraisal of a single taxon, featuring 252 drawings and black-and-white photographs, 96 color plates, nearly 100 appendix tables, and more than 4,000 bibliographic citations to original sources. The wealth of information and its integrated treatment will indisputably make the book the definitive source on dragonflies for years to come."

The present biodiversity crisis is rife with opportunities to make important conservation decisions; however, the misuse or misapplication of the methods and techniques of animal ecology can have serious consequences for the survival of species. Still, there have been relatively few critical reviews of methodology in the field. This book provides an analysis of some of the most frequently used research techniques in animal ecology, identifying their limitations and misuses, as well as possible solutions to avoid such pitfalls. In the process, contributors to this volume present new perspectives on the collection, analysis, and interpretation of data.

"Research Techniques in Animal Ecology" is an overarching account of central theoretical and methodological controversies in the field, rather than a handbook on the minutiae of techniques. The editors have forged comprehensive presentations of key topics in animal ecology, such as territory and home range estimates, habitation evaluation, population viability analysis, GIS mapping, and measuring the dynamics of societies. Striking a careful balance, each chapter begins by assessing the shortcomings and misapplications of the techniques in question, followed by a thorough review of the current literature, and concluding with possible solutions and suggested guidelines for more robust investigations.

While observing a family of elephants in the wild, Caitlin O'Connell noticed a peculiar listening behavior--the matriarch lifted her foot and scanned the horizon, causing the other elephants to follow suit, as if they could "hear" the ground. "The Elephant's Secret Sense" is O'Connell's account of her groundbreaking research into seismic listening and communication, chronicling the extraordinary social lives of elephants over the course of fourteen years in the Namibian wilderness.
This compelling odyssey of scientific discovery is also a frank account of fieldwork in a poverty-stricken, war-ravaged country. In her attempts to study an elephant community, O'Connell encounters corrupt government bureaucrats, deadly lions and rhinos, poachers, farmers fighting for arable land, and profoundly ineffective approaches to wildlife conservation. "The Elephant's Secret Sense "is ultimately a story of intellectual courage in the face of seemingly insurmountable obstacles.
"I was transported by the author's superbly sensuous descriptions of her years spent studying the animals. . . . Conjures a high-class nature documentary film in prose."--Steven Poole, "Guardian"
"A ride as rough and astonishing as the roads of the African floodplain."--Joan Keener, "Entertainment Weekly"
"A successful combination of science and soulfulness, explaining her groundbreaking theory of how elephants use seismic communication. . . . O'Connell's account is studded with sympathetic insights and well-turned phrases."--"Publishers Weekly"
"This fascinating book reads like a fast-paced detective story of a scientific discovery and adventure set in contemporary Africa. . . . By the end, O'Connell takes her rightful place among the leading biographers of the African elephant."--Iain Douglas-Hamilton, author of "Among the Elephants"""

Here we report on a 25-year long-term sequence of measures to return a deteriorated recreational urban lake, Alte Donau in Vienna to acceptable water quality. Metropolitan waters require focused ecosystem management plans and intensive in-lake efforts. We explored physico-chemical conditions, food web from viruses to fish and water birds, the sediments, the littoral zone and the catchment, management and urban planning, and global warming. Several restoration techniques were tested and critically evaluated. The final management plan was based on bi-stable theory. During the recovery phase, numerous surplus adjustments had to be implemented to secure sustainable achievement.

Red wolves are shy, elusive, and misunderstood predators. Until the 1800s, they were common in the longleaf pine savannas and deciduous forests of the southeastern United States. However, habitat degradation, persecution, and interbreeding with the coyote nearly annihilated them. Today, reintroduced red wolves are found only in peninsular northeastern North Carolina within less than 1 percent of their former range. In The Secret World of Red Wolves, nature writer T. DeLene Beeland shadows the U.S. Fish and Wildlife Service's pioneering recovery program over the course of a year to craft an intimate portrait of the red wolf, its history, and its restoration. Her engaging exploration of this top-level predator traces the intense effort of conservation personnel to save a species that has slipped to the verge of extinction.Beeland weaves together the voices of scientists, conservationists, and local landowners while posing larger questions about human coexistence with red wolves, our understanding of what defines this animal as a distinct species, and how climate change may swamp its current habitat.
