Journal of Zoology, EarlyView.In this study we tested the effects of insularity on amphibian colouration using the fire salamander as a model system. Although increased melanism was not a consistent pattern across all islands, salamanders from one island exhibited higher proportions of black pigmentation than mainland populations, while insular populations overall showed reduced ...

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

Interacción genotipo-ambiente: GGE Biplot y modelos AMMI [PDF]
, 2011 Los fenotipos son una mezcla del genotipo (G), el medio ambiente (E) y la interacción entre ellos (GEI). La interacción complica el proceso de selección de genotipos con rendimiento superior.

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 ...

Almacenamiento y acumulación de carbono en clones de caucho en la Orinoquía colombiana
Colombia ForestalLa 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 ...

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 ...

Genetic origins and climate‐induced erosion in economically important Asian walnuts
Conservation Biology, Volume 40, Issue 1, February 2026.Abstract The global climate is undergoing unprecedented changes, posing significant threats to species persistence. However, the spatiotemporal impacts on genetic diversity remain poorly understood, hindering species conservation and management. Walnuts, generally referred to as Juglans regia and J. sigillata, are economically vital in Asia, but little

New Phytologist, Volume 249, Issue 3, Page 1509-1526, February 2026.Summary Plastic responses of plants to their environment vary as a result of genetic differentiation within and among species. To accurately predict rangewide responses to climate change, it is necessary to characterize genotype‐specific reaction norms across the continuum of historic and future climate conditions comprising a species' range. The North
