The whole-site management of a Marine Protected Area (MPA) can increase the total abundance of reef species within its borders by up to 95%, according to new research.
The number of tree species on Earth
One of the most fundamental questions in ecology is how many species inhabit the Earth. However, due to massive logistical and financial challenges and taxonomic difficulties connected to the species concept definition, the global numbers of species, including those of important and well-studied life forms such as trees, still remain largely unknown. Here, based on global ground sourced data, we estimate the total tree species richness at global, continental, and biome levels.

New research from a cross-organisational consortium in the Amazon has found indigenous knowledge to be as accurate as scientific transect monitoring.
