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 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.
