Genetic and epigenetic insight into morphospecies in a reef coral
Incongruence between conventional and molecular systematics has left the delineation of many species unresolved. Reef-building corals are no exception, with phenotypic plasticity among the most plausible explanations for alternative morphospecies. As potential molecular signatures of phenotypic plasticity, epigenetic processes ...
Local adaptation limits lifetime reproductive success of dispersers in a wild salmon metapopulation
(University of Washington School of Aquatic & Fishery SciencesPublished by the journal "Nature Communications" at: http://www.nature.com/ncomms/2014/140417/ncomms4696/full/ncomms4696.html, 2014-10)
Demographic and evolutionary dynamics in wild metapopulations are critically affected by the balance between dispersal and local adaptation. Where populations are demographically interconnected by migration, gene flow is often assumed to prevent local adaptation. However, reduced fitness of immigrants may limit gene flow ...
Germline DNA methylation in reef corals: patterns and potential roles in response to environmental change
(Epigenetic Studies in Ecology and Evolution, 2015-10-01)
DNA methylation is an epigenetic mark that plays an inadequately understood role in gene regulation, particularly in non-model species. Because it can be influenced by the environment, DNA methylation may contribute to the ability of organisms to acclimatize and adapt to environmental change. We evaluated the distribution ...
Adult low pH exposure influences larval abundance in Pacific oysters (Crassostrea gigas)
As negative effects of ocean acidification are experienced by coastal ecosystems, there is a growing trend to investigate the effect ocean acidification has on multiple generations. Parental exposure to ocean acidification has been shown to induce larval carryover effects, but whether or not an acute exposure to a stressor ...
