A quantitative analysis to detect mass mortality events (wrecks) in Procellariiformes

open access: yesJournal of Applied Ecology, Volume 63, Issue 7, July 2026.
Our study provides the first systematic assessment of seabird mass mortality events in the South Atlantic and introduces a transferable statistical framework for detecting MMEs in other taxa and regions lacking baseline mortality information. By identifying recurrent temporal anomalies, high‐risk areas and vulnerable species, we could establish ...

Tree stem methane emissions are regulated by site‐level biogeochemistry over species identity in Amazon floodplain forests

open access: yesNew Phytologist, Volume 251, Issue 1, Page 179-190, July 2026.
Summary Tree stems in Amazonian floodplains emit substantial methane (CH4), yet controls on emission variability remain unclear. Emissions span orders of magnitude between várzea (nutrient‐rich) and igapó (nutrient‐poor) forests and among trees, suggesting controls beyond flooding.

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

Disentangling conservation asymmetries through socio‐economic transboundary factors across the Alto Paraná Atlantic Forest of South America

open access: yesPeople and Nature, Volume 8, Issue 5, Page 1328-1348, May 2026.
Abstract Ecoregions are often defined based on homogeneous biophysical and ecological conditions and are optimal spatial units for designing conservation strategies. However, transboundary ecoregions such as the Alto Paraná Atlantic Forest (APAF) experience asymmetrical conservation outcomes, understood here as cross‐border differences, resulting from ...
