Assessing differences among elasmobranch nurseries to aid conservation based on a genomics framework

Conservation Biology, Volume 40, Issue 4, August 2026.
Abstract Elasmobranch nurseries often differ in environmental conditions, demographics, and use patterns. These differences affect the distribution of genetic variation among nurseries. However, conservation and management strategies often fail to account for such differences because they are difficult to characterize.

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

Almacenamiento y acumulación de carbono en clones de caucho en la Orinoquía colombiana

Colombia Forestal
La estimación de biomasa es fundamental para conocer las reservas de carbono. En el paisaje de piedemonte y altillanura del departamento del Meta, Colombia, se calculó la biomasa aérea de nueve clones de Hevea brasiliensis por método directo en árboles ...

A response to ‘Quantifying phenotypic plasticity at multiple levels—A comment on Gómez et al.’

Functional Ecology, Volume 40, Issue 3, Page 560-562, March 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract In this reply, we clarify several conceptual misunderstandings raised in response to our Perspective on quantifying phenotypic plasticity. We emphasize that our central argument concerns the rigorous estimation of the magnitude of plasticity, rather than its mere ...

Long‐term comparison shows protected and non‐protected forests differ in harvesting, but not in wildfires or drought‐driven dieback

Journal of Applied Ecology, Volume 63, Issue 2, February 2026.
Lower forest harvesting in Natura 2000 sites may align with socio‐economic barriers often claimed by local communities, but protection does not influence vulnerability to other disturbances. In a general scenario of reduced forest harvesting in the region, we argue that differences in harvesting due to protection are statistically significant but ...
