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...
Strong Reproductive Isolation between Closely Related Tropical Sea Urchins (genus Echinometra)’
Reproductive Isolation Closely Related
2015/12/17
Morphological, mitochondrial DNA, and single-copy nuclear DNA differences show
that the tropical sea urchin Echinometra mathaei is composed of at least four
independent gene pools. Evolutionary di...
Killer storms: North Atlantic hurricanes and disease outbreaks in sea urchins

2014/4/17
An increase in the incidence of disease in various marine organisms over the past few decades has been linked
to ocean climate change. In Nova Scotia, Canada, mass mortalities of sea urchins, due to ...
CONSPECIFIC SPERM PRECEDENCE IN TWO SPECIES OF TROPICAL SEA URCHINS
TROPICAL SEA URCH CONSPECIFIC SPERM PRECEDENCE
2015/12/16
Conspecific sperm precedence occurs when females are exposed to sperm from males of multiple species,
but preferentially use sperm of a conspecific. Conspecific sperm precedence and...
A secondary chemical cue facilitates juvenile-adult postsettlement associations in red sea urchins

2014/5/8
Responses to predator odors or chemical alarm cues or both from conspecifics in aquatic systems generally involve a single chemical cue. We report a secondary chemical cue, released by adult red sea u...
Phylogeny and development of marine model species: strongylocentrotid sea urchins

2015/12/16
The phylogenetic relationships of ten strongylocentrotid sea urchin species were determined using
mitochondrial DNA sequences. This phylogeny provides a
backdrop for the evolutionary history of one ...
REPRODUCTIVE CHARACTER DISPLACEMENT AND THE GENETICS OF GAMETE RECOGNITION IN TROPICAL SEA URCHINS
Bindin positive selection reinforcemen
2015/12/16
Reproductive character displacement occurs when sympatric and allopatric populations of a species differ
in traits crucial to reproduction, and it is commonly thought of as a signal of selection acti...
