Abstract

<abstract abstract-type="main" id="jfb12566-abs-0001"> <title> <x xml:space="preserve">Abstract</x> </title> <p id="jfb12566-para-0001">The effect of UV radiation on habitat use of two species of intertidal fishes that inhabit the same pools but exhibit different activity levels and diets was measured: the highly active omnivorous <italic>Girella laevifrons</italic> and the cryptic carnivorous <italic>Graus nigra</italic>. Individuals of each species were acclimated to a tank divided in three sections with different illumination; no light (NL), ultraviolet light (UV) and white light (WL), and the time spent and number of visits to each section were recorded. Although both species preferred the NL section, <italic>G. laevifrons</italic> spent more time in UV and less time in WL compared with <italic>G. nigra</italic>; <italic>G. laevifrons</italic> also displayed higher number of visits to UV, suggesting a different tendency in space use in response to UV exposure in intertidal fishes.</p> </abstract>
