A Comparative Study on Satellite- and Model-Based Crop Phenology in West Africa
Remote Sensing, 2014 Crop phenology is essential for evaluating crop production in the food insecure regions of West Africa. The aim of the paper is to study whether satellite observation of plant phenology are consistent with ground knowledge of crop cycles as expressed in

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
