Sexual Segregation in Vertebrates
ISBN: 9780521184212 / Angielski / Miękka / 502 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. An understanding of sexual segregation is important in the explanation of life history and social preference, population dynamics and the conservation of rare species. This book explores the reasons why this behaviour has evolved and what factors contribute to it. Males and females of many species can, and do, live separately for long periods of time. This sexual segregation is widespread and can be on social, spatial or habitat scales.

Animals on Display: The Creaturely in Museums, Zoos, and Natural History
ISBN: 9780271060712 / Angielski / Miękka / 232 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. John Berger famously said that "in the last two centuries, animals have gradually disappeared." Those who share his view contend that animals have been removed from our daily lives and that we have been removed from the daily lives of animals. This has been the impetus for a plethora of representational practices that, broadly conceived, work to fill in the gap between humans and animals. Ironically, many of these may ultimately intensify the very nostalgia, distance, and ignorance they were devised to remedy. Animals on Display presents nine lively and engaging essays on the...

Some Studies on the Behavioral Ecology of Anuran Tadpoles
ISBN: 9783639345704 / Angielski / Miękka / 100 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Anuran tadpoles are favorite subjects for herpetologists because of their abundance, ease of culture, diversity, and adaptive strategies. In recent years these have served as model organisms in investigating many phenomena such as aggregation structure and function, kin recognition, prey- predator interactions, phenotypic plasticity, cannibalism, etc. The book is divided into 5 chapters. Chapter 1 deals with the ability of the tadpoles to asses the profitability of food habitats and distribute acordingly (ideal free distribution) is tested. Chapter 2 deals with mechanism of food ...

A Spider's World: Senses and Behavior
ISBN: 9783642075575 / Angielski / Miękka / 394 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Spiders are wonderful creatures. Their varied and complex range of behavior and highly developed sensory systems are excellently adapted to the environmental conditions - as is proven by their evolutionary success. Over 400 million years, spiders have developed their sensory organs to a fascinating technical perfection and complexity.
In his intriguing book, Professor Friedrich G. Barth puts this technical perfection into the context of "biology," in which the interaction between environment and sensory organs and the selectivity of the senses as a link between environment and behavior...
