This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Fragmentation, degradation and the loss of habitat are, among others, important drivers of human-induced biodiversity loss. Since half of the biodiversity can be found in tropical rainforests it is clear that the key to maintaining this biodiversity is the conservation of forests (Slingenberg et al. 2009). Primates are also severely affected by these threats since 90% of the primate species depend on forests for there survival (Mittermeier and Cheney 1987). This is also the case for the chimpanzee populations living in the DR Congo. The aim of this thesis is to characterise an unstudied population of chimpanzees living in three neighbouring forest fragments on the Lendu Plateau near Lake Albert. In recent decades the fragmentation in the area intensified. In 1985 the area consisted of a larger and small forest fragment. Nowadays the larger forest fragment is split up into two smaller fragments. In this study the tree composition of the forest was analysed. With Shannon indices (H) between 2.49 and 2.98, for the three fragments, the study area can be considered as moderately divers when considering tree species. Although the forest fragments are quite small the density of chimpanzees is quite high compared to other African forests. The density was estimated to be around 3.8 individuals per km2. This study found that night nests were more often found further away from human settlements and on higher altitudes. The data available for this thesis suggests that food trees are more likely to be used as nesting trees. In literature there is still a lot of debate and some articles suggest that other factors such as physical tree characteristics are more important for the selection of nesting trees (Stanford and OMalley 2008). This study shows that small forests can harbour threatened species and thus could be of importance for conservation.

Download or read book Great Ape Societies written by William C. McGrew and published by Cambridge University Press. This book was released on 1996-07-28 with total page 354 pages. Available in PDF, EPUB and Kindle. Book excerpt: The great apes (chimpanzees, bonobos, gorillas and orangutans) are our closest living relatives, sharing a common ancestor only five million years ago. We also share key features such as high intelligence, omnivorous diets, prolonged child-rearing and rich social lives. The great apes show a surprising diversity of adaptations, particularly in social life, ranging from the solitary life of orangutans, through patriarchy in gorillas to complex but different social organisations in bonobos and chimpanzees. As great apes are so close to humans, comparisons yield essential knowledge for modelling human evolutionary origins. Great Ape Societies provides comprehensive up-to-date syntheses of work on all four species, drawing on decades of international field work, zoo and laboratory studies. It will be essential reading for students and researchers in primatology, anthropology, psychology and human evolution.

Moore and published by . This book was released on 2013 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: Socioecological models derive from the field of behavioral ecology, wherein social strategies are seen as adaptive responses to evolutionary and environmental forces. Chimpanzee social structure is largely explained by their dietary preference, however, little is known of chimpanzee adaptations to savanna-woodland environments. This dissertation tests the explanatory power of socioecological models on a chimpanzee population occupying the savanna-woodlands of Ugalla, Tanzania. By conducting a genetic survey across 624 km 2 , the following predictions are tested: (1) chimpanzees will occur at lower population densities than at forested sites, reflective of more diffusely distributed resources; (2) lower population densities, resulting in theoretically indefensible larger home ranges, will decrease benefits gained from male philopatry, resulting in a more continuous distribution of Y-chromosome haplotypes than is characteristic of populations studied in forested environments; and (3) genetic diversity will be lower, compared to other eastern chimpanzee populations, due to potential isolation. The population density of Ugalla is 0.25 (CI 0.16-0.38) individuals/km 2 , which is ten times less than the lowest forested site density. The Ugalla males appear to remain in their natal community, as geographic clusters of rare Y-chromosome haplotypes were found, suggesting the maintenance of male-philopatric communities. Relative genetic diversity of the Y-chromosome was exceptionally low among the males, and autosomal diversity was comparable to other eastern chimpanzee populations. These results indicate that although chimpanzees in Ugalla occur at much lower densities in response to a savanna-woodland habitat, male philopatry is maintained, suggesting this social structure is a highly conservative adaptation, and one which may have been shared with our earliest ancestors as they shifted to a similar environment.
Download or read book Behavioural Diversity in Chimpanzees and Bonobos written by Christophe Boesch and published by Cambridge University Press. This book was released on 2002-08 with total page 300 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chimpanzees (Pan troglodytes) and bonobos (Pan paniscus), otherwise known as pygmy chimpanzees, are the only two species of the genus Pan. As they are our nearest relatives, there has been much research devoted to investigating the similarities and differences between them. This book offers an extensive review of the most recent observations to come from field studies on the diversity of Pan social behaviour, with contributions from many of the world's leading experts in this field. A wide range of social behaviours is discussed including tool use, hunting, reproductive strategies and conflict management as well as demographic variables and ecological constraints. In addition to interspecies behavioural diversity, this text describes exciting new research into variations between different populations of the same species. Researchers and students working in the fields of primatology, anthropology and zoology will find this a fascinating read.

Download or read book The Chimpanzees of the Ta Forest written by Christophe Boesch and published by . This book was released on 2000 with total page 336 pages. Available in PDF, EPUB and Kindle. Book excerpt: The chimpanzees are the closest living evolutionary relatives to our own species, Homo sapiens. As such, they have long exerted a fascination over those with an interest in human evolution, and what makes humans unique. Chrisophe Boesch and Hedwige Boesch-Acherman undertook an incredible observational study of a group of wild chimpanzees of the Tai forest in Cote D'Ivoire, spending some fifteen years in the West African jungle with them. This fascinating book is the result of these years of painstaking research among the chimps. Chimpanzee behavior is documented here in all its impressive diversity and variety. Aggression, territoriality, social structure and relationships, reproductive strategies, hunting, tool use - each of these is given its own chapter, along with topics such as chimp intelligence, life histories, and demography. The authors take care to place their observations within the broader context of research in behavioral ecology, and to compare and contrast their findings with other important work on chimpanzee groups, such as that by Jane Goodall. The book concludes with a summary chapter relating the chimpanzee findings to our understanding of human evolution. Combining careful scientific observation with a store of entertaining anecdotes, this is a lively and readable book. It also succeeds in shedding light on some of the central questions around the evolutionary relationships between the primates, and in particular the affinity between chimpanzees and humans. 'This is a major contribution to the study of the great apes, and a significant addition to debates about human/ape evolution. It has all the makings of a classic monograph.

Download or read book The Evolving Female written by Mary Ellen Morbeck and published by Princeton University Press. This book was released on 1996-12-09 with total page 353 pages. Available in PDF, EPUB and Kindle. Book excerpt: A human female is born, lives her life, and dies within the space of a few decades, but the shape of her life has been strongly influenced by 50 million years of primate evolution and more than 100 million years of mammalian evolution. How the individual female plays out the stages of her life--from infancy, through the reproductive period, to old age--and how these stages have been formed by a long evolutionary process, is the theme of this collection. Written by leading scholars in fields ranging from evolutionary biology to cultural anthropology, these essays together examine what it means to be female, integrating the life histories of marine mammals, monkeys, apes, and humans. The result is a fascinating inquiry into the similarities among the ways females of different species balance the need for survival with their role in reproduction and mothering. The Evolving Female offers an outlook integrating life history with an intimate examination of female life paths. Behavior, anatomy and physiology, growth and development, cultural identity of women, the individual, and the society are among the topics investigated. In addition to the editors, the contributors are Linda Fedigan, Kathryn Ono, Joanne Reiter, Barbara Smuts, Mariko Hiraiwa-Hasegawa, Mary McDonald Pavelka, Caroline Pond, Robin McFarland, Silvana Borgognini Tarli and Elena Repetto, Gilda Morelli, Patricia Draper, Catherine Panter-Brick, Virginia J.

Available in PDF, EPUB and Kindle. Book excerpt: Understanding the chimpanzee mind is akin to opening a window onto human consciousness. Many of our complex cognitive processes have origins that can be seen in the way that chimpanzees think, learn, and behave. The Mind of the Chimpanzee brings together scores of prominent scientists from around the world to share the most recent research into what goes on inside the mind of our closest living relative. Intertwining a range of topics—including imitation, tool use, face recognition, culture, cooperation, and reconciliation—with critical commentaries on conservation and welfare, the collection aims to understand how chimpanzees learn, think, and feel, so that researchers can not only gain insight into the origins of human cognition, but also crystallize collective efforts to protect wild chimpanzee populations and ensure appropriate care in captive settings. With a breadth of material on cognition and culture from the lab and the field, The Mind of the Chimpanzee is a first-rate synthesis of contemporary studies of these fascinating mammals that will appeal to all those interested in animal minds and what we can learn from them.

Download or read book The Chimpanzees of Bossou and Nimba written by Tetsuro Matsuzawa and published by Springer Science & Business Media. This book was released on 2011-05-06 with total page 464 pages. Available in PDF, EPUB and Kindle. Book excerpt: The chimpanzees of Bossou in Guinea, West Africa, form a unique community which displays an exceptional array of tool use behaviors and behavioral adaptations to coexistence with humans. This community of Pan troglodytes verus has contributed more than three decades of data to the field of cultural primatology, especially chimpanzees’ flexible use of stones to crack open nuts and of perishable tools during foraging activities. The book highlights the special contribution of the long-term research at Bossou and more recent studies in surrounding areas, particularly in the Nimba Mountains and the forest of Diécké, to our understanding of wild chimpanzees’ tool use, cognitive development, lithic technology and culture. This compilation of research principally strives to uncover the complexity of the mind and behavioral flexibility of our closest living relatives. This work also reveals the necessity for ongoing efforts to conserve chimpanzees in the region. Chimpanzees have shed more light on our evolutionary origins than any other extant species in the world, yet their numbers in the wild are rapidly declining. In that sense, the Bossou chimpanzees and their neighbors clearly embody an invaluable cultural heritage for humanity as a whole. Readers can enjoy video clips illustrating unique behaviors of Bossou chimpanzees, in an exclusive DVD accompanying the hardcover or at a dedicated website described in the softcover.
Download or read book Evolution of Nervous Systems written by Georg F. Striedter and published by Academic Press. This book was released on 2016-11-23 with total page 2064 pages. Available in PDF, EPUB and Kindle. Book excerpt: Evolution of Nervous Systems, Second Edition, Four Volume Set is a unique, major reference which offers the gold standard for those interested both in evolution and nervous systems. All biology only makes sense when seen in the light of evolution, and this is especially true for the nervous system. All animals have nervous systems that mediate their behaviors, many of them species specific, yet these nervous systems all evolved from the simple nervous system of a common ancestor. To understand these nervous systems, we need to know how they vary and how this variation emerged in evolution. In the first edition of this important reference work, over 100 distinguished neuroscientists assembled the current state-of-the-art knowledge on how nervous systems have evolved throughout the animal kingdom. This second edition remains rich in detail and broad in scope, outlining the changes in brain and nervous system organization that occurred from the first invertebrates and vertebrates, to present day fishes, reptiles, birds, mammals, and especially primates, including humans. The book also includes wholly new content, fully updating the chapters in the previous edition and offering brand new content on current developments in the field. Each of the volumes has been carefully restructured to offer expanded coverage of non-mammalian taxa, mammals, primates, and the human nervous system. The basic principles of brain evolution are discussed, as are mechanisms of change. The reader can select from chapters on highly specific topics or those that provide an overview of current thinking and approaches, making this an indispensable work for students and researchers alike. Presents a broad range of topics, ranging from genetic control of development in invertebrates, to human cognition, offering a one-stop resource for the evolution of nervous systems throughout the animal kingdom Incorporates the expertise of over 100 outstanding investigators who provide their conclusions in the context of the latest experimental results Presents areas of disagreement and consensus views that provide a holistic view of the subjects under discussion
