Biodiversity and ecosystem stability
2025-04-29
Microbial research suggests that biodiversity does not always increase ecosystem stability. Although many conservationists believe biodiversity is intrinsically valuable, the protection of biodiversity has also been argued for on the basis that diversity makes ecosystems healthier and more stable. But are highly diverse ecosystems more stable and productive than ecosystems with low diversity? The question has been investigated in plants and animals, where some evidence suggests a link between biodiversity and various measures of ecosystem function, but few studies have investigated the hypothesis’ applicability among microbes, ...
