Lichen bleaching as a response to long‐term experimental warming in the High Arctic

Functional Ecology, Volume 40, Issue 7, Page 2318-2331, July 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Lichens are an important component of Arctic ecosystems. Studies have indicated a decline in the abundance of Arctic lichens during recent decades, which is often attributed to competitive pressure from vascular plants.

Long‐term jaguar demography underscores the ecological value of Amazonian floodplains

Journal of Applied Ecology, Volume 63, Issue 7, July 2026.
Our results provide the first estimates of recruitment and apparent survival for Amazonian jaguars, key parameters for guiding conservation. We show that seasonal wetlands—the Amazonian floodplain forest and reported estimates from Pantanal and the Llanos—harbour the highest jaguar densities across the species' range.

Reef fish assemblages impacted by sponges overgrowing corals

Ecosphere, Volume 17, Issue 6, June 2026.
Abstract Numerous stressors are driving long‐term declines in coral cover on coral reefs, significantly impacting reef fish biodiversity and community structure. The benthic space made available by declining coral cover is often occupied by increases in other organisms, including macroalgae, encrusting ascidians, and sponges.

Effects of landscape context on avian specialist response to increased surface temperature in protected areas

Conservation Biology, Volume 40, Issue 3, June 2026.
Abstract Human development is a driver of global change and a major threat to biodiversity. Protected areas maintain and support biodiversity, but outside stressors, such as climate change and land use change, can negatively influence natural resources within protected areas.
