The study of alternative reproductive tactics (the behavioural strategies used by individuals to increase their reproductive success) is an evolutionary puzzle, and one of great interest to researchers. For instance, why do some males guard both nest and eggs, while others sneak into nests while pairs are spawning and fertilise those eggs? The field offers a special opportunity to study the evolution and functional causes of phenotypic variation, which is a general problem in the field of evolutionary biology. By integrating both mechanistic (psychological) and evolutionary (behavioural ecology) perspectives and by covering a great diversity of species, Alternative Reproductive Tactics addresses this integrated topic of longstanding interest, bringing together a multitude of otherwise scattered information in an accessible form that is ideal for graduate students and researchers.

How can the stunning diversity of social systems and behaviours seen in nature be explained? Drawing on social evolution theory, experimental evidence and studies conducted in the field, this book outlines the fundamental principles of social evolution underlying this phenomenal richness.To succeed in the competition for resources, organisms may either 'race' to be quicker than others, 'fight' for privileged access, or 'share' their efforts and gains. The authors show how the ecology and intrinsic attributes of organisms select for each of these strategies, and how a handful of straightforward concepts explain the evolution of successful decision rules in behavioural interactions, whether among members of the same or different species. With a broad focus ranging from microorganisms to humans, this is the first book to provide students and researchers with a comprehensive account of the evolution of sociality by natural selection.

The study of animal behaviour has become one of the fastest growing b- logical disciplines in recent decades. This development can be easily - ferred, for example, from the steady increase in the total number of pub- cations on any aspect of animal behaviour, in particular also in journals with a more general readership (e. g. Nature, Proceedings of the Royal - ciety or Current Biology), the ever-increasing number of participants at - ternational conferences (e. g. IEC or ISBE), and from the growing numbers of students choosing courses in this field. This development has several causes, of which I find three particularly compelling. First, it is incre- ingly being appreciated that behaviour is the crucial level at which an in- vidual's genotype and phenotype interface with the environment. Rec- nising behaviour as the main mechanism animals employ to ascertain their homeostasis, growth, survival and reproduction therefore provides a deep understanding of organismal integration and adaptation.Second, the ast- ishing success of the study of animal behaviour also has importantly to do with the intellectual flexibility and methodological inter-disciplinarity - quired for comprehensive analyses of behaviour. Today, students of beh- iour are jacks-of-all-trades; importing, applying and improving methods from many neighbouring disciplines, such as molecular genetics, physi- ogy or micro-electronics, as well as concepts and theories from less ob- ous sources, such as economics or sociology, for example.
