Book Description
Mammalian Dispersal Patterns examines the ways that social structure affects population genetics and, in turn, rates of evolution, in mammalian groups. It brings together fieldwork in animal behavior and wildlife biology with theoretical work in demography and population genetics. The focus here is dispersal—whether, how, and when individuals leave the areas where they are born. Theoretical work in population genetics indicates that such social factors as skewed sex ratios, restrictive mating patterns, and delayed age of first reproduction will lower the reproductive variability of a population by reducing the number of genotypes passed from one generation to the next. Field studies have shown that many mammalian species do exhibit many such social characteristics. Among horses, elephant seals, and a number of primates, the majority of females are inseminated by only a fraction of the males. In pacts of wolves and mongooses, usually only the highest-ranking male and female breed in a given season. Although socially restricted mating tends to lower genetic variability in isolated populations, it actually tends to increase genetic variability in subdivided populations with low rates of migration between subunits. Among some species there is little dispersal and thus little gene flow between subpopulations; other species travel far afield before mating. The contributors to this volume examine actual data from populations of mammals, the way patterns of dispersal correlate with the genetic structure of individuals and populations, and mathematical models of population structure. This interdisciplinary approach has an important bearing on work in conservation of both wildlife and zoo populations, for it shows that the home range and the population size needed to maintain genetic variability can differ greatly from one species to the next. The volume also offers a fruitful model for future research.

Book Description
The book aims to integrate our understanding of mammalian societies into a novel synthesis that is relevant to behavioural ecologists, ecologists, and anthropologists. It adopts a coherent structure that deals initially with the characteristics and strategies of females, before covering those of males, cooperative societies and hominid societies. It reviews our current understanding both of the structure of societies and of the strategies of individuals; it combines coverage of relevant areas of theory with coverage of interspecific comparisons, intraspecific comparisons and experiments; it explores both evolutionary causes of different traits and their ecological consequences; and it integrates research on different groups of mammals with research on primates and humans and attempts to put research on human societies into a broader perspective.

Book Description
This monograph is the result of eight years of bibliographical and field research concerning several behavioural ecology aspects of the Palaearctic falcons. For a while, this book grew along with “The Lanner falcon” published in 2015 and revised in 2017. In both books the main aim was to provide a clear overview of the biology and ecology of these species. In fact in the last 20 years, the number of publications on falcons has grown tremendously and, in parallel, also those belonging to the so-called "grey literature". The number of people involved is also increased by including both academics and nature lovers. Many previously published books emphasized identification, and offered little insights on the behavioural and ecological aspects of the species. Very often, the research on behavioural ecology remains closed within the confines of academic community. By contrast, a multitude of basic data is scattered in countless articles published in local magazines. Many falcon species are easy to observe and study (such as kestrels) but others are more rare and localized. In order to understand the survival strategies adopted by this group of avian predators, it is necessary not to lose sight of the overall picture. This book tries to explain the different survival strategies by examining, through a few essential chapters, some crucial aspects for all species. The first chapter provides information on the genus Falco, its genetics, evolution and morphological peculiarities. The other chapters deal with reproductive strategies, competition, exploitation of resources, dispersal patterns, communication and sociality. One of the main objectives of this book is to produce an accessible but scholarly curated source of reference. By understanding the most common species, it is possible to provide a working framework for rarer, and especially threatened, falcon species.

Book Description
A summary of much of the experimental work on the spatial ecology of small mammals. This field has entered an exciting stage with such new techniques as GIS and systems modeling becoming available. Leading contributors describe and analyze the most well-known case studies and provide new insights into how landscape patterns and processes have had an impact on small mammals and how small mammals have, in turn, affected landscape structure and composition.

Book Description
Numerous experts including ecologists, geneticists, paleontologists and climatologists, investigate the response of terrestrial organisms to changes in their environment. The volume comprises an introductory and a final chapter by the editors as well as another 35 contributions. These are divided into six sections: 1. past environmental changes - the late-Quaternary; 2. spatial responses to past changes; 3. mechanisms enabling spatial responses; 4. evolutionary responses to past changes; 5. mechanisms enabling evolutionary responses; 6. predicted future environmental changes and simulated responses. The overwhelming and unanimous conclusion of all contributors is that forecasted global environmental changes pose a severe threat to the integrity of ecosystems worldwide and to the survival of at least some species.
