Does life history predict past and current connectivity for rocky intertidal invertebrates across a marine biogeographic barrier?
TLDR
It is found that the ability to utilize sheltered habitat provides a clearer explanation of the phylogeographic break, and the species that displayed little or no evidence of a phyloGeographic break across the barrier each displayed unexpectedly relaxed habitat specificity.
Is life history a barrier to dispersal? Contrasting patterns of genetic differentiation along an oceanographically complex coast
TLDR
The results suggest that, although there is large scale genetic differentiation for two species, patterns of population connectivity are remarkably consistent within major regions and do not reflect variation in major oceanographic processes or genetic discontinuity coincident with biogeographic boundaries.
The importance of fine-scale environmental heterogeneity in determining levels of genotypic diversity and local adaptation
TLDR
The population genetics and mode of reproduction for the corals P. damicornis and S. hystrix showed unexpectedly high levels of genotypic diversity and appear to be maintained by sexual reproduction and different clonal genotypes show evidence of fine-scale adaptation to specific habitats.
Genetic subdivision in the subtidal, clonal sea anemone Anthothoe albocincta
TLDR
Data from an electrophoretic survey at six allozyme loci revealed that populations of A. albocincta, separated by up to 930 km, were at least moderately subdivided, and the sexual production of genotypically diverse larvae is the primary source of widely dispersed colonists and hence of new clones.
