nd the variety of the mechanisms involved. Many species regularly rely on their ability to home or reach other familiar sites, but how they manage to do this is often uncertain. In many cases the goal is attained in the absence of any sensory contact, by mechanisms of indirect orientation whose comp

Birds, winter and summer quarters, which may be far apart. The marked site fidelity of most species both when breeding and in winter, often even at stop-over sites, makes birds an ideal object of homing studies.

Invertebrates (excluding Arthropods),example barnacles among crustaceans and bivalves among molluscs, none the less, an increase in locomotor efficiency can be seen not only as a critical factor in reducing the risk of exposure to sources of stress but also as a means of improving resource exploitation and reducing intra- and interspecific competition.

无底

Fishes,ferred to as amphidromous, which migrate between fresh- and saltwater for purposes other than reproduction. Based on present information, McDowall (1988) listed 110 anadromous species, 56 catadromous species and 61 amphidromous species.

Reptiles,izards and related forms) and Ophidia (snakes) — inhabit arid or semi-arid environments, but some include freshwater bodies in their habitat and others are entirely marine. On the contrary, Loricata (crocodiles, alligators and gavials) inhabit mostly swamps, lakes and rivers, and only one species is definitely linked to coastal areas.
