Development, Ontogeny and Parasite-Mediated Changes in Social Behaviour

摘要: Tinbergen (1963) identified the development of a behavioural trait during an animal’s lifetime as one four key questions that should be asked about given in order to understand it. The study development, or ontogeny, sociality throughout animals’ lives provides insight both mechanisms and its functions. In this chapter, we examine first sociality. Many animal species spend initial stages life social environment, for example, if eggs are clustered young born into litter sibs. This means aggregation cohort kin is formed. These may subsequently go on form true group, based attraction, they simply remain together through philopatry, it can difficult distinguish between these. Nonetheless, attraction conspecifics early has been examined few conjunction with sensory locomotive capabilities, describe these here. Once ability identify locate developed, then likelihood seeking out others kind associate them groups governed by range factors. include early-life environment offspring, neural individuals, action hormones genetic predisposition animals We consider each relation expression further how relates ecological context which operates. Following from this, parasitism, near ubiquitous reality free-ranging animals, affects patterns association among animals.
