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...
Ocean acidification research in the ‘post-genomic’ era: Roadmaps from the purple sea urchin Strongylocentrotus purpuratus
Adaptation Climate change
2015/12/11
Advances in nucleic acid sequencing technology are removing obstacles that historically prevented use of genomics within ocean change biology. As one of thefirst marine calcifiers to have ...
DIFFERENCES IN THE REGULATION OF GROWTH AND BIOMINERALIZATION GENES REVEALED THROUGH LONG-TERM COMMON-GARDEN ACCLIMATION AND EXPERIMENTAL GENOMICS IN THE PURPLE SEA URCHIN
Climate change ecological genomics gene fl ow
2015/12/11
Across heterogeneous landscapes, populations may have adaptive differences in gene regulation that adjust their physiologies to
match local environments. Such differences could have origins in acclim...
Intraspecific divergence in sperm morphology of the green sea urchin, Strongylocentrotus droebachiensis: implications for selection in broadcast spawners
sperm morpholog sea urchin,
2015/12/11
Sperm morphology can be highly variable among species, but less is known about
patterns of population differentiation within species. Most studies of sperm morphometric
variation are done in species...

Spawning events in small and large populations of the green sea urchin Strongylocentrotus droebachiensis as recorded using fertilization assays
Spawning events in small large populations of the green sea urchin Strongylocentrotus droebachiensis recorded using fertilization assays
2014/5/4
During the winter and spring of 2002 and 2003, we used time-integrated fertilization assays to monitor sperm availability in three populations of the green sea urchin Strongylocentrotus droebachiensis...
Recent speciation in the Indo-West Pacific: rapid evolution of gamete recognition and sperm morphology in cryptic species of sea urchin
speciation bindin Okinawa
2015/12/16
The rich species diversity of the marine Indo-West Pacific (IWP) has been explained largely on the basis
of historical observation of large-scale diversity gradients. Careful study of divergence amon...
Sea urchin spawning in benthic boundary layers: Are eggs fertilized before advecting away from females?
Sea urchin spawning benthic boundary layers eggs fertilized before advecting females
2014/5/20
Past work on fertilization in echinoids and other egg-broadcasting, free-spawning invertebrates suggests that these organisms might be extremely sperm limited in the field unless individuals spawn in ...
