The deleterious effects of hybridization are a serious concern for the conservation and management of species, particularly when populations mix as a result of human activity. Outbreeding depression is the typical result observed in early-generation interpopulation hybrids of Tigriopus californicus. We examined both controlled crosses and long-term,(More)
The prevalence of F2 hybrid breakdown in interpopulation crosses of the marine copepod Tigriopus californicus can be explained by disruption of coadapted gene complexes. This study further dissects the nature of hybrid gene interactions, revealing that parental populations may also harbor maladapted gene complexes. Diagnostic molecular markers (14) were(More)
For the intertidal copepod Tigriopus californicus, outbreeding depression for a variety of fitness measures is typically observed in early-generation interpopulation hybrids. We examined both controlled crosses and long-term, freely mating experimental hybrid swarms composed of individuals from Baja California (Mexico) populations Playa Altamira and Punta(More)
