This thesis is a comparative study of the biology and evolution of soldier producing aphids. I
first provide a comprehensive review of all published literature on the soldier producing …

Studies of social behavior cover a broad spectrum of interactions, from short‐term pairing
between individuals to more complex interactions within and among groups that have stable …

FEMALE Drosophila melanogaster with environmentally1–3 or genetically4 elevated rates
of mating die younger than controls. This cost of mating is not attributable to receipt of …

Despite the depiction of nature" red in tooth and claw", cooperation is actually widespread in
the animal kingdom. Various types of cooperative behaviors have been documented in …

This book is about the genetics and behaviour of individuals within colonies of social insects-
bees, wasps, ants, and termites. Colonial living is characterized by division of labour and …

Paternity is often determined by competition between the ejaculates of different males.
Males can also use particular behaviours or structures to manipulate how females use …

Interactions among conspecifics influence social evolution through two distinct but intimately
related paths. First, they provide the opportunity for indirect genetic effects (IGEs), where …

Hamilton's inclusive fitness rule shows that the evolution of altruism is facilitated by high
genetic relatedness of altruists to their beneficiaries. But the evolution of altruism is inhibited …

In this book, the biologist Raghavendra Gadagkar focuses on the single species he has
worked on throughout his career. Found throughout southern India, Ropalidia marginata is a …

High-resolution genetic markers have revolutionized our understanding of vertebrate mating
systems, but have so far yielded few comparable surprises about kinship in social insects …
