Temporal and spatial variation in population structure among brooding sea stars in the genus Leptasterias

Ecology and Evolution, 2021
Temporal genetic studies of low‐dispersing organisms are rare. Marine invertebrates lacking a planktonic larval stage are expected to have lower dispersal, low gene flow, and a higher potential for local adaptation than organisms with planktonic ...

Generating continuous maps of genetic diversity using moving windows

Methods in Ecology and Evolution, 2023
Genetic diversity plays a key role in maintaining population viability by preventing inbreeding depression and providing the building blocks for adaptation.

Inference From Gene to Population: Propagating Uncertainty In Estimates of Population Characteristics Through Ecological Scales [PDF]

, 2010
A current trend in population biology is the increasing realisation of the effect of individual variability on some of the big patterns of population dynamics.

Demographic history and genomics of local adaptation in blue tit populations

Evolutionary Applications, 2020
Understanding the genomic processes underlying local adaptation is a central aim of modern evolutionary biology. This task requires identifying footprints of local selection but also estimating spatio‐temporal variations in population demography and ...

Multiple waves of freshwater colonization of the three-spined stickleback in the Japanese Archipelago

BMC Evolutionary Biology, 2020
Background The three-spined stickleback (Gasterosteus aculeatus) is a remarkable system to study the genetic mechanisms underlying parallel evolution during the transition from marine to freshwater habitats.

Evolution of an Amazonian Fish Is Driven by Allopatric Divergence Rather Than Ecological Divergence

Frontiers in Ecology and Evolution, 2022
Lowland central Amazonia is characterized by heterogeneous riverscapes dominated by two chemically divergent water types: black (ion-poor, rich in dissolved organic carbonate and acidic) and white (rich in nutrient and turbid) waters.

Genetics of adaptation: Experimental test of a biotic mechanism driving divergence in traits and genes

Evolution Letters, 2019
The genes underlying adaptations are becoming known, yet the causes of selection on genes—a key step in the study of the genetics of adaptation—remains uncertain.

Adaptive substitutions underlying cardiac glycoside insensitivity in insects exhibit epistasis in vivo

eLife, 2019
Predicting how species will respond to selection pressures requires understanding the factors that constrain their evolution. We use genome engineering of Drosophila to investigate constraints on the repeated evolution of unrelated herbivorous insects to

An eDNA-Based SNP Assay for Ungulate Species and Sex Identification

Diversity, 2017
Many processes in wild populations are difficult to study. Genetic data, often non-invasively collected, may provide a solution to these difficulties and are increasingly used to study behavioral, demographic, ecological, and evolutionary processes ...
