Cold Shock Compromises the Electrically Mediated Block to Polyspermy in Lytechinus variegatus Eggs. [PDF]
Mol Reprod DevABSTRACT Exposure to low temperature prior to insemination increases the likelihood of polyspermy in Lytechinus variegatus eggs. Electrophysiological recordings reveal that cold shock partially disrupts the egg's action potential, producing a subthreshold depolarization during the fertilization response.

Shotgun Mitogenomics Provides a Reference Phylogenetic Framework and Timescale for Living Xenarthrans [PDF]
, 2015 Xenarthra (armadillos, sloths, and anteaters) constitutes one of the four major clades of placental mammals. Despite their phylogenetic distinctiveness in mammals, a reference phylogeny is still lacking for the 31 described species. Here we used Illumina

The roles of inter- and intra-sexual selection in behavioral isolation between native and invasive pupfishes [PDF]
, 2017 Male-male competition and female mate choice may both play important roles in driving and maintaining reproductive isolation between species. When previously allopatric species come into secondary contact with each other due to introductions, they ...
