Stability in tapia woodlands amid non‐native expansion: Integrating traditional ecological knowledge and remote sensing to track 73 years of tree cover in Madagascar

People and Nature, Volume 8, Issue 5, Page 1403-1418, May 2026.
Abstract Afromontane ecosystems, characterised by mosaics of fire‐adapted grassy ecosystems and fire‐sensitive forests, are biodiversity hotspots facing escalating pressures from non‐native species, climate and land‐use change. Madagascar's Central Highlands is one such hotspot, hosting woodlands dominated by endemic Uapaca bojeri (tapia) which are ...

Spatial Distribution of European Grayling Reflects Longitudinal Temperature Patterns in a Swiss River

Ecology of Freshwater Fish, Volume 35, Issue 1, January 2026.
ABSTRACT Most salmonid populations are declining across their entire habitat range, partly because of large‐scale loss of crucial physical habitats. Alterations in river flow and temperature resulting from climate change are likely to further degrade habitat quality, particularly summer thermal conditions experienced by temperature‐sensitive fish ...

Congo Basin Carbon Cycle Responses to Global Change

Global Change Biology, Volume 32, Issue 1, January 2026.
Understanding the resilience of the Congo Basin carbon cycle in the face of current and future pressures requires a detailed understanding of its response to past and present drivers of change. Building on a pantropical framework of drivers and possible regional mechanisms for resilience, this review provides the first comprehensive assessment of Congo

DeepForestVision: Automated wildlife identification for camera traps of African tropical forests

Ecological Solutions and Evidence, Volume 6, Issue 4, October–December 2025.
Chimpanzees (Pan troglodytes) observed on camera trap in Kibale National Park, Uganda. This frame was extracted from a 30 s video classified as chimpanzee by DeepForestVision with a confidence score of 0.99 (©Sebitoli Chimpanzee Project). Abstract Tropical forests are rich in biodiversity but face the rapid loss of their wildlife due to increasing ...
