= "the scientific study of the function and evolution of animal
behaviour patterns". The term is associated with the work of TINBERGEN
& LORENZ. and the concepts of INNATE RELEASING MECHANISM (IRM) and
FIXED ACTION PATTERN. These related to the immediate causation of
behaviour. Hinde (1982) refers to 4 questions about behaviour:
= a more recent term (cf Krebs and Davies, 1983, 1991) for work
which particularly emphasises the ADAPTIVE FUNCTION of behaviour. As Hinde
(1982) says, "the boundary between ethology and behavioural ecology is
now impossible to define."
= a term coined by Wilson (1975). It can be seen as a sub-division
of behavioural ecology: for present purposes it is another name for work
which asks biological/evolutionary questions about social behaviour, and
tends to emphasise unlearned causes of behaviour.
