The need for carbon finance schemes to tackle overexploitation of tropical forest wildlife
Conservation Biology, Volume 39, Issue 1, February 2025.Abstract Defaunation of tropical forests, particularly from unsustainable hunting, has diminished populations of key seed dispersers for many tree species, driving shifts in forest community composition toward small‐fruited or wind‐dispersed trees with low wood density. Such shifts can reduce aboveground biomass, prompting calls for overexploitation to
