Comparative ecology of three species of Thamnodynastes (Serpentes, Dipsadidae) in subtropical-temperate South America
(British Herpetological Society, 2014-04)
Two hypotheses have been proposed to explain the differences among species within present-day communities: the competition-predation hypothesis (CPH) and the deep history hypothesis (DHH). However, the lack of information ...
Trophic structure on the West Antarctic Peninsula shelf: Detritivory and benthic inertia revealed by delta(13)C and delta(15)N analysis
(PERGAMON-ELSEVIER SCIENCE LTD, 2008)
Summer bloom-derived phytodetritus settles rapidly to the seafloor on the West Antarctic Peninsula (WAP) continental shelf, where it appears to degrade relatively slowly, forming a sediment ""food bank"" for benthic ...
