A Framework to Analyze Primate Species Vulnerability to Trade in Urban Markets

open access: yesAmerican Journal of Primatology, Volume 87, Issue 12, December 2025.
A primate‐focused conservation criminology framework to examine taxon‐specific vulnerability to live trade in urban markets. ABSTRACT Live primates are increasingly commodified and appropriated as inputs into markets, both at the international and domestic scales, and across physical and online platforms.

Biogeography and biodiversity of gastropod molluscs from the eastern Brazilian continental shelf and slope Biogeografía y biodiversidad de moluscos gastrópodos de la plataforma y talud continental brasileño

open access: yesLatin American Journal of Aquatic Research, 2009
Biogeographic distributional patterns of gastropods are proposed based on the species' geo-graphic and bathymetric distribution. Samples were collected along the Brazilian continental margin between 18° S and 23° S, at 37 stations with depths from 20 m ...

Marked tree demographic variation along subtle elevation differences partially explains species' habitat associations in an Amazonian forest

open access: yesJournal of Ecology, Volume 113, Issue 10, Page 2860-2874, October 2025.
These findings show that even small differences in elevation can lead to biologically meaningful variation in resource access that translates into significant differences in tree growth and survival. However, resource access could not fully explain the patterns of topographically driven demographic variation we observed. While certain species may still

¿Existen migraciones verticales en el zooplancton de la Laguna de Los Padres?

open access: yesBiología Acuática, 2019
Diel vertical migration is a widely studied phenomenon occurring specially in marine and well stratified continental systems. The aim of this work was to study the spatial distribution of zooplankters in a «pampasic» shallow lake and to look for the ...

Probabilistic modelling improves relative dating from gene phylogenies

open access: yesMethods in Ecology and Evolution, Volume 16, Issue 10, Page 2461-2471, October 2025.
Abstract Establishing the timing of past evolutionary events is a fundamental task in the reconstruction of the history of life. State‐of‐the‐art molecular dating methods generally involve the reconstruction of a species tree from conserved, vertically evolving genes and the assumption of a molecular clock calibrated with the fossil record.

Microbial drivers of root plasticity

open access: yesNew Phytologist, Volume 248, Issue 1, Page 52-67, October 2025.
Summary Soils are highly heterogeneous and dynamic systems, experiencing a constant flow of plant root exudates and moisture fluctuations that affect nutrient distribution, soil physicochemical properties, and microbial metabolisms. Plant roots adjust their development within the soil matrix (growth, branching, root angle, and anatomical features) by ...

It is cool to be clear: Transparency induces a thermal cost in clearwing butterflies

open access: yesFunctional Ecology, Volume 39, Issue 9, Page 2452-2464, September 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract In butterflies, wing transparency raises the question of potential costs for vital functions, such as thermoregulation. The thermal melanism hypothesis posits that darker colorations enable higher absorption of solar radiation, leading to the prediction that such ...

Distribución de foraminíferos bentónicos (Protozoa: Foraminiferida) en la ensenada Quillaipe (41°32' S; 72°44' O), Chile: Implicaciones para el estudio del nivel del mar Distribution of benthic foraminifera (Protozoa: Foraminiferida) in the Quillaipe Inlet (41°32' S; 72°44' W), Chile: Implications for sea level studies

open access: yesRevista Chilena de Historia Natural, 2010
Los foraminíferos de las marismas salobres son utilizados como indicadores del cambio producido en el nivel del mar durante el Holoceno. No obstante, los foraminíferos de las marismas de Chile han sido escasamente estudiados por lo que se desconoce la ...
