There are boxed sections for a few themes and marginal notes support advisor the reader. The booklet should be crucial interpreting for college students of behavioural ecology, animal behaviour and evolutionary biology. [From publisher's blurb.]

Behavioural ecology is, essentially, modern day common heritage and there's no clearer written, extra inspiringly enthusiastic advisor to the topic out there. This booklet units the most excellent for behavioural ecology and animal behaviour textbooks so one can without doubt proceed to notify and pleasure scholars and researchers in equivalent degree for a few years to come."

Example text

Sheep use horns for fighting and deer use antlers. Horns are derived from skin while antlers are derived from bone. The differences between horns and antlers need not necessarily reflect ecological differences; it may simply be a case of evolution working with different raw materials to produce the same functional end. The problem with non-adaptive explanations is that they are hypotheses of the last resort. Further scientific enquiry is stifled. Maybe there is an adaptive explanation for the difference but we just haven’t discovered it yet.

Further reading The classic books by Niko Tinbergen (1974) and Bert Hölldobler and Edward O. Wilson (1994) convey the delight of watching and wondering in the field. The books by Richard Dawkins (1982, 1989) explain why evolution favours behaviour that benefits Natural Selection, Ecology and Behaviour 23 individuals and genes, rather than species and groups. Reeve and Sherman (1993) provide a lucid discussion of the distinctions between Tinbergen’s four questions and the inter-relationships between them.

However, the most recent comparative studies have attempted to control for these various problems, and we will now discuss other examples, bearing the criticisms in mind, to illustrate how changes in methodology have made comparison between species a more rigorous exercise. Comparative approach to primate ecology and behaviour As with the weaver birds and antelopes, primates vary in their social organization (Fig. 4). There are solitary insectivores, like tarsiers, which live in forests and are nocturnal.
