Amphibians' Expansion to Record Elevations Influences Chytrid (Batrachochytrium dendrobatidis) Infection Dynamics

open access: yesBiotropica, Volume 58, Issue 2, March 2026.
Peruvian frogs underwent a climate‐driven range expansion into deglaciating mountains, exposing themselves and their fungal pathogen Batrachochytrium dendrobatidis (Bd) to challenging new thermal environments. Bd has dispersed extensively in these new habitats, and elevation may mediate the apparent sublethal impacts of infection for frogs.

Low abundance of phytophagous nematodes under invasive exotic Pinus elliottii – enemy release and plant–soil feedbacks

open access: yesNew Phytologist, Volume 249, Issue 6, Page 3060-3071, March 2026.
Summary According to the enemy release hypothesis (ERH), the fitness of exotic plants and their capacity to become invasive in their area of introduction may partly be attributable to the loss of their natural enemies. Invasive species may also benefit from modifying soil attributes and thereby creating a positive soil–plant feedback.

Ungulate prey availability to inform Mexican wolf recovery within its historical range

open access: yesThe Journal of Wildlife Management, Volume 90, Issue 2, February 2026.
We estimated the potential ecological carrying capacity for the Mexican wolf based exclusively on ungulate prey biomass estimated from camera trap surveys. In the United States, the potential density estimate is high (21.4–52.7 wolves/1,000 km2) owing to the presence and relatively high densities of elk, mule deer, and white‐tailed deer.

Indigenous peoples and local community reports of climate change impacts on biodiversity

open access: yesConservation Biology, Volume 40, Issue 1, February 2026.
Abstract Climate change impacts on biodiversity have been primarily studied through ecological research methods, largely ignoring other knowledge systems. Indigenous and local knowledge systems include rich observations of changes in biodiversity that can inform climate change adaptation planning and environmental stewardship.

Mapping the density of giant trees in the Amazon

open access: yesNew Phytologist, Volume 249, Issue 1, Page 152-168, January 2026.
Summary Tall trees (height ≥ 60 m) are keystone elements of tropical forests, strongly influencing biodiversity, carbon storage, and ecosystem resilience. Yet, their density and spatial distribution remain poorly quantified, especially in remote Amazonian regions, limiting our understanding of their ecological roles and contribution to forest–climate ...
