Multigenerational hybridisation results in heterosis and facilitates adaptive introgression, with no evidence of outbreeding depression in a pair of marine gastropods

D Cummins, M Johnson, J Tomkins, J Kennington - 2024 - researchsquare.com
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

J Hudson, CD McQuaid, M Rius - Journal of Evolutionary …, 2021 - academic.oup.com

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 …

AK Chhina, KA Thompson, D Schluter - bioRxiv, 2020 - biorxiv.org
The fitness of hybrids is a critical determinant of gene flow between hybridizing populations.
If hybrid phenotypes change predictably as parental populations become increasingly …

Environmental impacts on hybridization outcomes

Rapid evolutionary responses in a translocated population of intertidal snail (Bembicium vittatum) utilise variation from different source populations

RM Binks, WJ Kennington, MS Johnson - Conservation Genetics, 2007 - Springer
The artificial movement of individuals between populations (translocation) can be an
effective way to increase genetic diversity within populations, but few studies have …

Fine-scale contemporary recombination variation and its fitness consequences in adaptively diverging stickleback fish

V Venu, E Harjunmaa, A Dreau, S Brady… - Nature Ecology & …, 2024 - nature.com
Despite deep evolutionary conservation, recombination rates vary greatly across the
genome and among individuals, sexes and populations. Yet the impact of this variation on …

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 …

Inbreeding vs outbreeding depression in a marine species with low dispersal potential

C Montecinos, C Álvarez, R Riera, A Brante - Marine Ecology, 2021 - Wiley Online Library
Inbreeding depression strongly affects the biological fitness of organisms throughout their
life cycle. These negative effects are more pronounced in species with low dispersal …
