Multigenerational hybridisation results in heterosis and facilitates adaptive introgression, with no evidence of outbreeding depression in a pair of marine gastropods
Anthropogenic environmental changes continue to threaten species globally. On the one
hand, anthropogenic movement of species has caused unintentional hybridisation, which …

[HTML][HTML] Translocation precipitates natural hybridisation and pervasive introgression between marine gastropods with divergent developmental modes
D Cummins, MS Johnson, JL Tomkins… - Biological …, 2023 - Elsevier
Assisted colonisation, the introduction of species beyond their historical range, is
increasingly necessary for conserving species. However, empirical evidence of the long …

Contemporary climate change hinders hybrid performance of ecologically dominant marine invertebrates
Human activities alter patterns of biodiversity, particularly through species extinctions and
range shifts. Two of these activities are human mediated transfer of species and …

Long‐term genetic monitoring reveals contrasting changes in the genetic composition of newly established populations of the intertidal snail Bembicium vittatum
W Jason Kennington, TH Hevroy… - Molecular …, 2012 - Wiley Online Library
Newly established populations are susceptible to founder events that reduce genetic
variation. This may be counterbalanced by gene flow after populations become established …

Rapid evolutionary responses in a translocated population of intertidal snail (Bembicium vittatum) utilise variation from different source populations
The artificial movement of individuals between populations (translocation) can be an
effective way to increase genetic diversity within populations, but few studies have …

Marine genetic swamping: hybrids replace an obligately estuarine fish
DG Roberts, CA Gray, RJ West, DJ Ayre - Molecular Ecology, 2010 - Wiley Online Library
Populations of obligately estuarine taxa are potentially small and isolated and may lack
genetic variation and display regional differentiation as a result of drift and inbreeding …
