This book describes one of our closest relatives, the orangutan, and the only extant great ape in Asia. It is increasingly clear that orangutan populations show extensive variation in behavioral ecology, morphology, life history, and genes. Indeed, on the strength of the latest genetic and morphological evidence, it has been proposed that orangutans actually constitute two species which diverged more than a million years ago - one on the island of Sumatra the other on Borneo, with the latter comprising three subspecies.
This book has two main aims. The first is to carefully compare data from every orangutan research site, examining the differences and similarities between orangutan species, subspecies and populations. The second is to develop a theoretical framework in which these differences and similarities can be explained. To achieve these goals the editors have assembled the world's leading orangutan experts to rigorously synthesize and compare the data, quantify the similarities or differences, and seek to explain them.
Orangutans is the first synthesis of orangutan biology to adopt this novel, comparative approach. It analyses and compares the latest data, developing a theoretical framework to explain morphological, life history, and behavioral variation. Intriguingly, not all behavioral differences can be attributed to ecological variation between and within the two islands; relative rates of social learning also appear to have been influential. The book also emphasizes the crucial impact of human settlement on orangutans and looks ahead to the future prospects for the survival of critically endangered natural populations.

A Best Book of 2020: The Washington Post * NPR * Chicago Tribune * Smithsonian A "remarkable" (Los Angeles Times), "seductive" (The Wall Street Journal) debut from the new cohost of Radiolab, Why Fish Don't Exist is a dark and astonishing tale of love, chaos, scientific obsession, and--possibly--even murder. "At one point, Miller dives into the ocean into a school of fish...comes up for air, and realizes she's in love. That's how I felt: Her book took me to strange depths I never imagined, and I was smitten." --The New York Times Book Review David Starr Jordan was a taxonomist, a man possessed with bringing order to the natural world. In time, he would be credited with discovering nearly a fifth of the fish known to humans in his day. But the more of the hidden blueprint of life he uncovered, the harder the universe seemed to try to thwart him. His specimen collections were demolished by lightning, by fire, and eventually by the 1906 San Francisco earthquake--which sent more than a thousand discoveries, housed in fragile glass jars, plummeting to the floor. In an instant, his life's work was shattered. Many might have given up, given in to despair. But Jordan? He surveyed the wreckage at his feet, found the first fish that he recognized, and confidently began to rebuild his collection. And this time, he introduced one clever innovation that he believed would at last protect his work against the chaos of the world. When NPR reporter Lulu Miller first heard this anecdote in passing, she took Jordan for a fool--a cautionary tale in hubris, or denial. But as her own life slowly unraveled, she began to wonder about him. Perhaps instead he was a model for how to go on when all seemed lost. What she would unearth about his life would transform her understanding of history, morality, and the world beneath her feet. Part biography, part memoir, part scientific adventure, Why Fish Don't Exist is a wondrous fable about how to persevere in a world where chaos will always prevail.

The karst landforms of China are renowned around the world for the beauty of their landscapes, but it is less well appreciated that they also contain extensive cave systems with very significant underwater habitats. China also has an extremely high level of biodiversity, including over 1,500 freshwater fish species. Unsurprisingly, some of these species inhabit the karst cave systems and have flourished and diversified under unique environmental conditions. As a result, cave fishes in China are particularly abundant and diverse when compared to those of other countries of the world. These remarkable fishes have received considerable research attention from Chinese ichthyologists and, for the first time, this book makes their resulting findings directly accessible to the English-speaking world through a remarkable endeavour of Sino-British collaboration.

A book of evocative and atmospheric photographs taken by Dick Hawkes to create a representative record of this precious and ecologically unique habitat - before much of it is lost to the many threats it faces. Chalk streams have been described as England's "rainforest". Around 85% of the world's chalk streams are in England. They are beautiful, biologically distinct and amazingly rich in wildlife, but are under threat from man-made issues of abstraction, pollution from chemicals and effluent, development for housing, and climate change. Included in the book are images of typical habitats and species of wildlife found in chalk streams and water meadows, highlighting those that are rare or most under threat.

Unlike some other reproductions of classic texts (1) We have not used OCR(Optical Character Recognition), as this leads to bad quality books with introduced typos. (2) In books where there are images such as portraits, maps, sketches etc We have endeavoured to keep the quality of these images, so they represent accurately the original artefact. Although occasionally there may be certain imperfections with these old texts, we feel they deserve to be made available for future generations to enjoy.

Tony Hutson illuminates the nocturnal world of bats and examines how they have adapted to habitats in every corner of the world. Beginning with the fossil record and what it reveals about their relationship to other mammals, Hutson discusses their unique aerodynamics and their extraordinary feats of echolocation. He discusses their life cycle, diet and foraging strategy, breeding, roosting, and migration patterns as well as their predators, parasites, and man-made threats to their ecosystem. Bats are long-lived mammals which can form enormous colonies containing tens of millions of creatures, a concentration of mammals paralleled only by human cities. Topically, the book looks at the viruses harboured and tolerated by bats and their impact on humans. The book also contains an appendix of bat families and subfamilies and gives details of the number of genera or species, distribution, size, roost habitat and diet.

Conservation Physiology for the Anthropocene - A Systems Approach, Volume 39B in the Fish Physiology series, is a comprehensive synthesis related to the physiology of fish in the Anthropocene. This volume helps solve knowledge gaps by considering the many ways in which different physiological systems (e.g., sensory physiology, endocrine, cardio-respiratory, bioenergetics, water and ionic balance and homeostasis, locomotion/biomechanics, gene function) and physiological diversity are relevant to the management and conservation of fish and fisheries. Chapters in this release include Using physiology for recovering imperiled species - the Delta smelt, Conservation hatcheries - the Sturgeon story, Aquatic pollutants and stressors, and more. Other sections discuss Fisheries interactions in a multi-stressor world, Environmental change in riverine systems - Amazon basin stressors, Environmental change in lakes and wetlands - East African basin stressors, Coral reef fish in a multi-stressor world, Polar fish in a multi-stressor world, Physiology informs fisheries restoration and habitat management, A physiological perspective on fish passage and entrainment, Invasive species control and management - the sea lamprey story, and On the conservation physiology of fishes for tomorrow.

Behavioral Ecology of Tropical Birds, Second Edition provides the most updated and comprehensive review on the evolution of behavior in tropical landbirds. The book reviews gaps in our knowledge that were identified twenty years ago when the first edition was published, highlights recent discoveries that have filled those gaps, and identifies new areas in urgent need of study. It covers key topics, including timing of breeding, movement ecology, life history traits, slow vs. fast pace of life, mating systems, mate choice, territoriality, communication, biotic interactions, and conservation. Written by international experts on the behavior of tropical birds, the book explores why the tropics is a unique natural laboratory to study the evolution of bird behavior and why temperate zone species are so different. A recent surge of studies on tropical birds has helped to reduce the temperate zone bias that arose because most avian model species in behavioral ecology were adapted to northern temperate climates. This is an important resource for researchers, ecologists and conservationists who want to understand the rich and complex evolutionary history of avian behavior.

How does a mudskipper fish manage to “walk� on land? Why is the Hoatzin also known as ‘The Stinkbird’? And once the female Pipa toad has laid her eggs, where does she put them? The answers? The mudskipper can “walk� using its pectoral fins, the Hoatzin has a unique digestive system which gives the bird a manure-like odour, and the female Pipa Toad embeds its eggs on its back where they develop to adult stage. Illustrated throughout with outstanding colour photographs, Strange Animals presents the most unusual aspects of 100 of the most unusual species. The selection spans a broad spectrum of wildlife, from the tallest land living mammal, the giraffe, to the light, laughing chorus of Australian kookaburra birds, from the intelligence of the Bottlenose dolphin to octopuses that change colour when they dream to the slow pace of the three-toed sloth. Arranged geographically, the photographs are accompanied by fascinating captions, which explain the quirky characteristics of each entry. Including egg-laying mammals, birds, reptiles, amphibians, cannibalistic insects and other invertebrates, Strange Animals is a compelling introduction to some of nature’s most curious beasts.
