A study authored by researchers at the US Geological Survey, along with group of international scientists, has used new techniques to isolate effects of biodiversity, and further confirmed that biodiversity is necessary for ecosystem health.
These findings help resolve a question about whether species diversity is necessary to maintain the health of ecosystems around the world, and may guide policy makers in how to respond to the effects of climate change on biodiversity moving forward.
