All males are not created equal: Fertility differences depend on gamete recognition polymorphisms in sea urchins
created equal gamete recognition polymorphisms
2015/12/17
Behaviors, morphologies, and genetic loci directly involved in
reproduction have been increasingly shown to be polymorphic
within populations. Explaining how such variants are maintained
by selecti...
Whole-Genome Positive Selection and Habitat-Driven Evolution in a Shallow and a Deep-Sea Urchin
positive selection dN/dS
2015/12/11
Comparisons of genomic sequence between divergent species can provide insight into the action of natural
selection across many distinct classes of proteins. Here, we examine the extent of positive se...
The Secret Life of Marine Mammals: Novel Tools for Studying Their Behavior and Biology at Sea
Marine Mammals Behavior and Biology
2015/8/19
Given the interest by both the lay and scientific communities, it is surprising how little is known about the open ocean ecology of marine mammals. Their patchy distribution and low abundance leads to...

Chemical Ecology Marine Biodiversity Insights and Products the Sea
2015/8/13
Tremendous attention has been focused on the loss of and threats to, terrestrial biodiversity. Until very recently (Norse, 1993), much less attention was devoted to marine biodiversity despite the fac...
