Are numbers of species a true measure of ecosystem health?
Some scientists see it as evidence of how species adapt, while others see it as a sign that common invasive species, such as rats and mosquitoes, are the real winners. … Many local ecosystems — at least as measured by “species richness,” the number of species they contain — appear to be in good health.
