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

open access: yesWildlife 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

Evolution of Reproductive Plasticity in a Seasonal Tropical Environment

open access: yesEcology Letters, Volume 29, Issue 5, May 2026.
We reveal widespread occurrence of seasonal reproductive plasticity, including reproductive diapause, in Nymphalid butterflies in a seasonal rainforest in the Amazon. This highlights that, not only in temperate but also tropical habitats, seasonality is an important driver of plastic life history strategies. ABSTRACT Seasonality can drive the evolution

Height and phytotelm size affect the invertebrate communities of epiphytic bromeliads in the Amazon rainforest

open access: yesEcological Entomology, Volume 51, Issue 2, Page 221-234, April 2026.
The height at which epiphytic bromeliads are found affects the invertebrate community composition within them. The size of epiphytic bromeliads is positively correlated with species richness of both aquatic and terrestrial invertebrates. Whether bromeliads were found in primary or secondary forest did not have a significant effect on the community of ...
