Effects of selective harvest on antler size of white‐tailed deer in Texas, USA

Wildlife Monographs, Volume 222, Issue 1, June 2026.
We conducted 20 years of experiments on the selective harvest of white‐tailed deer by antler size, judged inferior, in 2 areas of South Texas, USA. Selective harvest increased the phenotypic antler size of older males in one study area but not the other. There was little evidence of evolution resulting from selective harvesting. Abstract There has been

Plant functional diversity does not dilute virus infection, but community virus prevalence positively correlates with net C3 grass production

Journal of Ecology, Volume 114, Issue 2, February 2026.
This study examines if plant functional diversity dilutes plant virus prevalence in grass hosts and evaluates how virus prevalence influences net community and host production. Functional diversity did not mitigate or amplify virus prevalence. While we found that species relationships between virus prevalence and production varied, overall, virus ...

Meristic co‐evolution and genomic co‐localization of lateral line scales and vertebrae in Central American cichlid fishes

Ecology and Evolution, Volume 14, Issue 9, September 2024.
We dissect the co‐evolution and genetic architecture of lateral line scale counts and vertebrae numbers in Neotropical Heroine cichlids. Our phylogenetic comparative analyses recovered a positive correlation between these two traits. Furthermore, our qualitative traits locus (QTL) analyses identified significant genomic co‐localized associations for ...

Thermal plasticity has higher fitness costs among thermally tolerant genotypes of Tigriopus californicus

Functional Ecology, Volume 38, Issue 7, Page 1562-1577, July 2024.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Under climate change, ectotherms will likely face pressure to adapt to novel thermal environments by increasing their upper thermal tolerance and its plasticity, a measure of thermal acclimation. Ectotherm populations with high thermal tolerance are often less thermally
