Eco‐evolutionary maintenance of diversity in fluctuating environments

M Yamamichi, AD Letten, SJ Schreiber - Ecology Letters, 2023 - Wiley Online Library
Growing evidence suggests that temporally fluctuating environments are important in
maintaining variation both within and between species. To date, however, studies of genetic …

Rapid evolutionary change, constraints and the maintenance of polymorphism in natural populations of Drosophila melanogaster

A Glaser‐Schmitt, TJS Ramnarine… - Molecular …, 2024 - Wiley Online Library
Allele frequencies can shift rapidly within natural populations. Under certain conditions,
repeated rapid allele frequency shifts can lead to the long‐term maintenance of …

Linking the spatial and genomic structure of adaptive potential for conservation management: a review

AK Chhina, N Abhari, A Mooers, J Lewthwaite - Genome, 2024 - cdnsciencepub.com
We unified the recent literature with the goal to contribute to the discussion on how genetic

Identification of heterokaryon incompatibility genes in Aspergillus fumigatus highlights a narrow footprint of ancient balancing selection

B Auxier, J Zhang, FR Marquez, K Senden… - BioRxiv, 2022 - biorxiv.org
In fungi, a phenomenon termed heterokaryon incompatibility restricts hyphal fusion to occur
within an individual since fusion between individuals leads to cell death. Generally, the …
