Gamete Morphology of Six Species of Sea Urchins in Saipan, CNMI
نویسندگان
چکیده
• General sperm shape characterized by conical head • Eggs characterized as large spheres in vitelline membrane • Atlantic and Pacific populations’ spermatozoa show major morphological differences from each other (Landry et al. 2003) • Western Pacific species’ sperm head length measured twice that of Central Pacific (Marks et al. 2008). • Deep sea sperm head length elongated compared to shallow water species (Eckelbarger et al. 1989b) • Same area and depth in Saipan, CNMI

Natural hybridization in the sea urchin genus Pseudoboletia between species without apparent barriers to gamete recognition.
Marine species with high dispersal potential often have huge ranges and minimal population structure. Combined with the paucity of geographic barriers in the oceans, this pattern raises the question as to how speciation occurs in the sea. Over the past 20 years, evidence has accumulated that marine speciation is often linked to the evolution of gamete recognition proteins. Rapid evolution of ga...
متن کاملRecent speciation in the Indo-West Pacific: rapid evolution of gamete recognition and sperm morphology in cryptic species of sea urchin.
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 among closely related species can reveal important new information about the pace and mechanisms of their formation, and can illuminate the genesis of biogeographic patterns. Young species inhabiting th...
متن کاملContemporary evolution of sea urchin gamete-recognition proteins: experimental evidence of density-dependent gamete performance predicts shifts in allele frequencies over time.
Species whose reproductive strategies evolved at one density regime might be poorly adapted to other regimes. Field and laboratory experiments on the sea urchin Strongylocentrotus franciscanus examined the influences of the two most common sperm-bindin alleles, which differ at two amino acid sites, on fertilization success. In the field experiment, the arginine/glycine (RG) genotype performed b...
متن کاملPositive selection and sequence rearrangements generate extensive polymorphism in the gamete recognition protein bindin.
Bindin is a gamete recognition protein of sea urchins that mediates species-specific attachment of sperm to an egg-surface receptor during fertilization. Sequences of bindin from closely related urchins show fixed species-specific differences. Within species, highly polymorphic bindin alleles result from point substitution, insertion/deletion, and recombination. Since speciation, positive selec...
متن کاملEvolutionary animation: how do molecular phylogenies compare to Mayr's reconstruction of speciation patterns in the sea?
Ernst Mayr used the geography of closely related species in various stages of increasing divergence to "animate" the process of geographic, or allopatric, speciation. This approach was applied to a wide set of taxa, and a seminal paper by Mayr used it to explore speciation patterns in tropical sea urchins. Since then, taxonomic information in several of these genera has been augmented by detail...
