This book presents some results on selected taxa in the Himalayan region (mainly Nepal), pinpoints the threats to their survival and suggests ways how to avoid their extinction. Most chapters are based on graduate research projects – relatively long-term field studies. The data presented here can be a good source of updated information on the subject and will prove to be a very useful reference in future studies of Himalayan biodiversity. They also tend to pinpoint the existing gaps in our knowledge of this region. All the chapters are based on recent trends of biodiversity and conservation vision, so the book can be a potential alternative to the existing relatively older books with outdated vision and information. Its main goal, however, is to disseminate the information about biodiversity conservation problems in the Himalayan region among the people in the developed world. The book can serve as a good source of reference or even as a textbook for both graduate and undergraduate students in conservation biology and mountain ecology.

Snow leopard (Panthera uncia) is an endangered species, and its population size is steadily declining. The main threats to the snow leopard include illegal trade, conflict with locals (human-snow leopard conflict), lack of conservation, awareness and policy, and climate change. To avoid its extinction, we badly need a good knowledge of its ecology, distribution and population dynamics, including interactions with its prey, which will take into account various scenarios of changes in climate and human impact on snow leopard. This book aims to put together a considerable amount of unpublished data collected by the co-author of most of the chapters, Bikram Shrestha, which might be useful for other researchers working on snow leopard. In addition, researchers might find it useful to have a key for determining the diet of snow leopard based on remnants of its food in its scats. Last, but not least, based on the difficulty we experienced trying to compare and combine different sets of results, we propose a general methodology for collecting data. Thus, this book is not an all-encompassing compendium, but an attempt to fill some gaps in the literature and to show, how to publish new data on snow leopard in a useful and workable way. The first part, describing the main features of snow leopard and its main prey ecology, is followed by a comprehensive review of data available on its abundance and threats to its survival. The third, most extensive part-the substance of the book-presents new data from 15 years of intensive camera trapping combined with scat sampling. These data are analyzed by means of advances GIS and genetic techniques, which yields a large amount of conservation implications. The purpose of this book is to provide a tool for both environmental managers and researchers to find quickly what is known about this species for conservation planning and for an effective protection of snow leopard. However, enthusiasts interested in wild cats may welcome the book, too.

This book is concerned with the general principles and theories of population ecology, based on the idea that the rules governing the dynamics of populations are relatively simple, and that the rich behavior we observe in nature is a consequence of the structure of the system rather than of the complexity of the underlying rules. From this perspective, the dynamic behavior of single-species populations is examined and an elementary feedback model of the population system is developed. This single-species model is refined and generalized by examining the mechanisms of population regulation. Graphical procedures are developed for evaluating the behavior of populations inhabiting variable environments, which are then applied to the analysis of interactions between two species. Finally, spatial effects on population behavior and communities composed of many interacting species are examined.

This book presents completely novel, yet unpublished findings on aphid population dynamics and ecology in the context of recent environmental changes and closely related issues. It can be used as complementary text in any course on population dynamics and ecology of crop pests at undergraduate or graduate levels. The book is intended mainly for graduate students, researchers in crop science, crop protection, agricultural advisors and managers, but it will surely attract attention of many other people interested in insect pests, their biological control and ecology.
