Precise foraging schedule in an intertidal euopisthobranch mollusk
ABSTRACT Most studies of foraging in shell-less gastropods have focused on the ubiquitous generalist sea hares (family Aplysiidae; subfamily Aplysiinae: Aplysia spp., Dolabella spp). Here we studied movement in a specialist sea hare (the seacat, Dolabrifera dolabrifera; subfamily Dolabriferinae). Seacats in each of 7 different tidepools on Isla Naos in the Gulf of Panama emerged precisely when the daytime ebbing tide fell below the height of their pool, returning to their hiding places within 1-3 hours. This short, precise foraging pattern contrasts sharply with long, variable schedule of the generalist sea-hares. Combined with their reduced chemical and behavioral defenses, these observations on seacats raise the possibility that they are avoiding predators during high tides and at night.
期刊介绍:
Marine and Freshwater Behaviour and Physiology is devoted to the publication of papers covering field and laboratory research into all aspects of the behaviour and physiology of all marine and freshwater animals within the contexts of ecology, evolution and conservation.
As the living resources of the world’s oceans, rivers and lakes are attracting increasing attention as food sources for humans and for their role in global ecology, the journal will also publish the results of research in the areas of fisheries biology and technology where the behaviour and physiology described have clear links to the contexts mentioned above.
The journal will accept for publication Research Articles, Reviews, Rapid Communications and Technical Notes (see Instructions for authors for details). In addition, Editorials, Opinions and Book Reviews (invited and suggested) will also occasionally be published. Suggestions to the Editor-In-Chief for Special Issues are encouraged and will be considered on an ad hoc basis.
With the goal of supporting early career researchers, the journal particularly invites submissions from graduate students and post-doctoral researchers. In addition to recognising the time constraints and logistical limitations their research often faces, and their particular need for a prompt review process, accepted articles by such researchers will be given prominence within the journal (see Instructions for authors for details).
