Integrated demographic strategies are more strongly associated with variation in conspecific density dependence than single traits in tropical tree seedlings

Journal of Ecology, Volume 114, Issue 2, February 2026.
Species‐specific conspecific negative density dependence (CNDD) varied widely among tropical tree species. CNDD was strongest in fast‐growing species and tall, long‐lived pioneers, weakly related to most functional traits except wood density and strongest in rare species. These results show that integrated life‐history strategies explain CNDD variation

Emergence, spread, and impact of high‐pathogenicity avian influenza H5 in wild birds and mammals of South America and Antarctica

Conservation Biology, Volume 40, Issue 1, February 2026.
Abstract The currently circulating high‐pathogenicity avian influenza (HPAI) virus of the subtype H5 causes variable illness and death in wild and domestic birds and mammals, as well as in humans. This virus evolved from the Goose/Guangdong lineage of the HPAI H5 virus, which emerged in commercial poultry in China in 1996, spilled over into wild birds,

Effects of organized guarding on mortality from human–elephant conflict in northeast India

Conservation Biology, Volume 40, Issue 1, February 2026.
Abstract Human–elephant conflict (HEC) frequently results in human and elephant mortality, posing major social justice and conservation concerns across Asia and Africa. Although a variety of interventions have been introduced to mitigate HEC, rigorous evaluations of how they affect mortality are practically nonexistent.

Plant science meets the decision‐making process of restoration in quarries and waste dumps of a remote archipelago

Ecological Solutions and Evidence, Volume 6, Issue 4, October–December 2025.
Restoration experiments in degraded quarries of the Galápagos Islands test innovative water‐saving techniques. The photo shows experimental plots at Floreana Black Gravel Quarry (2014 and 2024), where long‐term monitoring evaluates plant survival and growth.

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

Journal 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

Community‐informed and codesigned research to understand the impacts of railways on wildlife

Conservation Biology, Volume 39, Issue 5, October 2025.
Abstract Trains cause mortalities of several animal species, but the ecological impacts of railways are understudied. Most research on wildlife–train collisions has focused on large mammals, but understanding railway‐specific risks for underrepresented taxa, especially vulnerable species, is important for developing effective mitigation strategies ...
