ICYMI: New online! Mangrove biodiversity and ecosystem services
Mangrove biodiversity and ecosystem services
Nature Reviews Biodiversity, Published online: 17 November 2025; doi:10.1038/s44358-025-00103-3Mangroves are valued for their diverse range of ecosystem services, but the role of biodiversity in supporting these services is not thoroughly understood. This Review examines the relationships between biodiversity, ecosystem processes and ecosystems services, and examines how future research could address knowledge gaps to guide effective, equitable mangrove conservation.

Tree-planting is always good, right? Well, it turns out that a tree planted in the wrong place can actually have a negative impact on the climate. That’s why a research team with scientists from The Nature Conservancy developed maps to help with strategic reforestation for maximum benefit!
New maps help decision-makers factor albedo into tree-planting plans
Albedo can cause large reductions to the climate benefit of tree planting – but new science helps identify locations with greatest climate-cooling potential
