Abstract: Abstract The sexy‐sperm hypothesis posits that polyandrous females derive an indirect fitness benefit from multi‐male mating because they increase the probability their eggs are fertilized by males whose sperm have high fertilizing efficiency, which is… read more here.

DOI: 10.1016/j.ibmb.2018.12.002
Abstract: The male ejaculate contains a multitude of seminal fluid proteins (SFPs), many of which are key reproductive molecules, as well as sperm. However, the identification of SFPs is notoriously difficult and a detailed understanding of… read more here.

DOI: 10.1093/ee/nvy108
Abstract: Abstract Cosmopolitan pests can consist of geographic populations that differ in their current host ranges or in their ability to colonize a novel host. We compared the responses of cowpea-adapted, seed-beetle populations (Callosobruchus maculatus [F.]… read more here.

DOI: 10.1093/jee/toz117
Abstract: Abstract Cowpea, Vigna unguiculata (L.) Walp., serves as a major source of dietary protein in many tropical and subtropical regions around the world. To identify loci associated with agronomically desirable traits, eight elite cowpea cultivars… read more here.

DOI: 10.1111/imb.12271
Abstract: The seed beetle Callosobruchus maculatus is a significant agricultural pest and increasingly studied model of sexual conflict. Males possess genital spines that increase the transfer of seminal fluid proteins (SFPs) into the female body. As… read more here.
