Using customs data to understand overlooked trade in non‐CITES birds between Africa and Asia

open access: yesConservation Biology, Volume 40, Issue 4, August 2026.
Abstract The international trade in live birds poses risks to animals, people, and biodiversity. To effectively mitigate these risks, decision‐makers require information on the volume, dynamics, and direction of trade. Despite Africa once being the largest exporter of birds by region, very little data exist on recent trade in live birds not listed on ...

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

European mistletoe shares a similar demographic strategy with non‐parasitic plants

open access: yesJournal of Ecology, Volume 114, Issue 5, May 2026.
European mistletoe (Viscum album) does not have a distinct demographic strategy from non‐parasitic plants, as quantified by time‐based life history traits. We found that mistletoe vital rates were driven by mistletoe size and position in the host tree.

Morphological, Molecular, and Isotopic Approaches to Termite Ecology: A Mangrove Case Study

open access: yesBiotropica, Volume 58, Issue 3, May 2026.
Termite communities in Caribbean mangroves, though species‐poor, sustain crucial decomposition and nutrient cycling. Their overlapping niches and stochastic assembly highlight termites' resilience and ecological importance in supporting the functioning of these challenging coastal ecosystems.

Placental insufficiency markers to assess the risk of non‐chromosomal genetic conditions in early‐onset fetal growth restriction

open access: yesUltrasound in Obstetrics &Gynecology, Volume 67, Issue 4, Page 492-499, April 2026.
ABSTRACT Objectives To assess the value of placental insufficiency markers for estimating the risk of genetic anomalies in fetuses with isolated early‐onset fetal growth restriction (FGR), defined as an estimated fetal weight ≤ 3rd percentile diagnosed ≤ 28 + 6 weeks' gestation.
