Heat stress in tropical highland regions: the case of Kenya during February 2024

Weather, EarlyView.
Understanding and awareness about heat stress remain low in sub‐Saharan countries despite high exposure and vulnerability. After the national media in Kenya reported that people had complained about unusual heat stress during February 2024, we combine in situ and reanalysis data to (i) put this event into climatological perspective, and (ii) give ...

Scaling from microsite to landscape to resolve litter decomposition dynamics in globally extensive drylands

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Decomposition is the transformation of dead organic matter into its inorganic constituents. In most biomes, decomposition rates can be accurately predicted with simple mathematical models, but these models have long under‐predicted decomposition in globally extensive ...
