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 ...

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

Potential of very high resolution remote sensing gor the estimation of oil palm leaf areal index (LAI) [PDF]
, 2009 A fast, reliable, and objective estimation of oil-palm leaf area index, or LAI, which is directly related with canopy response to global environmental change, could help the management of large industrial estates towards precision farming in several ways.
