Melanism in salamanders: effects of insularity, sex and size on dorsal colouration in Salamandra salamandra

open access: yesJournal of Zoology, Volume 329, Issue 4, Page 340-352, August 2026.
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

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

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

open access: yesFunctional 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 ...

Produção e composição de genótipos de cana-de-açúcar

open access: yesBoletim de Indústria Animal, 2013
Foi desenvolvido no Instituto de Zootecnia, em Nova Odessa, SP, um experimento para avaliar 60 genótipos de cana-de-açúcar, com vistas à alimentação animal. Utilizou-se o delineamento de blocos ao acaso, com 3 repetições. As produções de matéria seca foram semelhantes, todavia, com grande amplitude de variação nos dados.

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

open access: yesJournal 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 ...

Association analysis between a VNTR intron 8 polymorphism of the dopamine transporter gene (SLC6A3) and obsessive- compulsive disorder in a Brazilian sample Análise de associação entre um polimorfismo VNTR no intron 8 do gene do transportador de dopamina (SLC6A3) e transtorno obsessivo-compulsivo em uma amostra brasileira

open access: yesArquivos de Neuro-Psiquiatria, 2007
Family, twin and segregation analysis have provided evidences that genetic factors are implicated in the susceptibility for obsessive-compulsive disorder (OCD).
