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 ...

Ecological Genetics and Air Pollution [PDF]

, 1991
Human activities influence the chemical and physical properties of the atmosphere; examples are increases in troposphere concentrations of ozone, carbon dioxide, oxides of nitrogen and sulfur, heavy metals and UV-B radiation.

Species integrity, introgression, and genetic variation across a coral reef fish hybrid zone

Ecology and Evolution, 2020
Hybridization and introgression are evolutionarily significant phenomena breaking down species boundaries. “Hybrid zones” (regions of species overlap and hybridization) enable quantification of hybridization frequency and examination of mechanisms ...

Plate reduction in southern Japanese freshwater populations of threespine stickleback (Gasterosteus aculeatus)

Ecology and Evolution, 2023
Adaptation to similar environments can lead to the evolution of similar phenotypes in phylogenetically independent lineages. However, the extent of parallel evolution often varies.

Bacterial Lux Biosensors in Genotoxicological Studies

Biosensors, 2023
The aim of this study was to assess the applicability of the bacterial lux biosensors for genotoxicological studies. Biosensors are the strains of E.

Host specificity and genetics of host resistance in the "Daphnia-Pasteuria" host-parasite system [PDF]

, 2012
Antagonistic coevolution plays an important role in a large number of evolutionary and ecological phenomena. Furthermore, according to the Red Queen Theory coevolution between hosts and their parasites may explain the maintenance of sexual reproduction ...

Ecological genetics in the North Atlantic: environmental gradients and adaptation at specific loci [PDF]

, 2008
The North Atlantic intertidal community provides a rich set of organismal and environmental material for the study of ecological genetics. Clearly defined environmental gradients exist at multiple spatial scales: there are broad latitudinal trends in ...

Adaptive limitations of white spruce populations to drought imply vulnerability to climate change in its western range

Evolutionary Applications, 2019
A cost‐effective climate change adaptation strategy for the forestry sector is to move seed sources to more northern and higher elevation planting sites as part of ongoing reforestation programs.
