The tropics and subtropics are home to about 75% of the global human population. Cultural, economic, and political circumstances vary enormously across this vast geography of some 170 countries and territories. The regions not only harbor the world's poorest countries but their human populations are growing disproportionally faster than in temperate zones. Some countries are developing rapidly -- Brazil, China, India, and Mexico being obvious examples, while others still remain in the poverty trap. This region contains an astonishing proportion of global biodiversity; some 90% of plant and animal species by some measures. Its contribution to human well-being is astounding. It was the birthplace for our species; and it hosts a myriad of plant and animal species which products feed us, keep us healthy, and supply us with a variety of material goods. The tropics and subtropics are also a natural laboratory where some of humanity's most important scientific discoveries have been made. Such biodiversity has enormous implications for research priorities, capacity building, and policy to address the challenges of conserving this region. Tropical Conservation: Perspectives on Local and Global Priorities drew the majority of its contributors from this growing pool of scientists and practitioners working in Latin America, Africa, and Asia. It introduces important conservation concepts and illustrates their application as the authors directly capture real world experiences in their home countries in preventing biodiversity loss and sustaining ecological health. Today, no part of the world can be viewed in isolation, and we further codify and integrate a range of approaches for addressing global threats to nature and environmental sustainability, including climate change and emerging diseases. Five sections structure the major themes.

This volume was created initially from a symposium of the same name presented at the International Primatological Society's XVIII Congress in Adelaide. South Australia. 6-12 January 2000. Many of the authors who have contributed to this text could not attend the symposium. so this has become another vehicle for the rapidly growing discipline of Fragmentation Science among primatologists. Fragmentation has quickly become a field separate from general ecology. which underscores the severity of the situation since we as a planet are rapidly losing habitat of all types to human disturbance. Getting ecologists. particularly primatologists. to admit that they study in fragments is not easy. In the field of primatology. one studies many things. but rarely do those things (genetics. behavior. population dynamics) get called out as studies in fragmentation. For some reason "fragmentation primatologists" fear that our work is somehow "not as good" as those who study in continuous habitat. We worry that perhaps our subjects are not demonstrating as robust behaviors as they "should" given fragmented or disturbed habitat conditions. I had a colleague openly state that she did not work in fragmented forests. that she merely studied behavior when it was clear that her study sites. everyone of them. was isolated habitat. Our desire to be just another link in the data chain for wild primates is so strong that it makes us deny what kinds of habitats we are working in. However.

From the Arctic to South Africa - one finds them everywhere: Ants. Making up nearly 15% of the entire terrestrial animal biomass, ants are impressive not only in quantitative terms, they also fascinate by their highly organized and complex social system. Their caste system, the division of labor, the origin of altruistic behavior and the complex forms of chemical communication makes them the most interesting group of social organisms and the main subject for sociobiologists. Not least is their ecological importance: Ants are the premier soil turners, channelers of energy and dominatrices of the insect fauna. TOC:The importance of ants.- Classification and origins.- The colony life cycle.- Altruism and the origin of the worker caste.- Colony odor and kin recognition.- Queen numbers and domination.- Communication.- Caste and division of labor.- Social homeostasis and flexibility.- Foraging and territorial strategies.- The organization of species communities.- Symbioses among ant species.- Symbioses with other animals.- Interaction with plants.- The specialized predators.- The army ants.- The fungus growers.- The harvesters.- The weaver ants.- Collecting and culturing ants.- Glossary.- Bibliography.- Index.

This book is an important addition to the knowledge of lobster research. The book complements other books published on lobster research and management as it focuses on Indian lobster fisheries and aquaculture developments where there have been nearly 350 research papers and reports and 19 PhD awards. The book has 15 chapters written by international experts covering many aspects of the biology of a number of spiny and slipper lobster species occurring in India and world oceans with maps illustrating global distribution of spiny lobster families, genera and species. An updated taxonomy and checklist of marine lobsters, the status and management of lobster fisheries in India and Indian Ocean Rim countries and a review of aquaculture research in India and other major countries have also been presented. The book is timely as the 2nd International Indian Ocean Expedition (IIOE) is currently underway (2015-2020), 50 years after the original IIOE (1959-1965), with some of the original lobster research on the biology and distribution of phyllosoma larvae being undertaken on the plankton samples collected during the first IIOE. Many of the chapters are contributed by the authors from Central Marine Fisheries Research Institute (CMFRI), which has been collecting fishery and biological data on lobsters since 1950 when lobster fishing began on a subsistence scale, followed by some industrial fishing for lobsters in different parts of India. Unfortunately, the development of some of these lobster fisheries was followed by overfishing due to lack of enforcement of regulations. The book provides a valuable addition to our knowledge of the biology, fisheries and aquaculture of spiny and slipper lobsters.

We live in a time of unprecedented planetary ecocrisis, one that poses the serious and ongoing threat of mass extinction. Drawing upon a range of theoretical influences, this book offers the foundations of a philosophy of ecopedagogy for the global north. In so doing, it poses challenges to today's dominant ecoliteracy paradigms and programs, such as education for sustainable development, while theorizing the needed reconstruction of critical pedagogy itself in light of our presently disastrous ecological conditions.

Since its discovery Antarctica has held a deep fascination for biologists. Extreme environmental conditions, seasonality and isolation have lead to some of the most striking examples of natural selection and adaptation on Earth. Paradoxically, some of these adaptations may pose constraints on the ability of the Antarctic biota to respond to climate change. Parts of Antarctica are showing some of the largest changes in temperature and other environmental conditions in the world. In this volume, published in association with the Royal Society, leading polar scientists present a synthesis of the latest research on the biological systems in Antarctica, covering organisms from microbes to vertebrate higher predators. This book comes at a time when new technologies and approaches allow the implications of climate change and other direct human impacts on Antarctica to be viewed at a range of scales; across entire regions, whole ecosystems and down to the level of species and variation within their genomes. Chapters address both Antarctic terrestrial and marine ecosystems, and the scientific and management challenges of the future are explored.

It is a great honor to be asked to introduce this exciting new volume, having been heavily involved in the first comprehensive synthesis in the early 1980s. Gibbons are the most enthralling of primates. On the one hand, they are the most appealing animals, with their upright posture and body shape, facial markings, dramatic arm-swinging locomotion and suspensory postures, and devastating duets; on the other hand, the small apes are the most diverse, hence biologically valuable and informative, of our closest relatives. It is hard for me to believe that it is 40 years to the month since I first set foot on the Malay Peninsula to start my doctoral study of the siamang. I am very proud to have followed in the footsteps of the great pioneer of primate field study, Clarence Ray Carpenter (CR or Ray, who I was fortunate to meet twice, in Pennsylvania and in Zurich), first in Central America (in 1967) and then in Southeast Asia. It is 75 years since he studied howler monkeys on Barro Colorado Island in the Panama Canal Zone. It is 70 years since he studied the white-handed gibbon in Thailand.
