Ecosystems change long before species are lost
Rice U. researchers take detailed look at how biodiversity within species impacts communities Communities in nature are likely to be a lot more sensitive to change than previously thought, according to a new study at Rice University.
The study, which appears this week in Nature Communications, shows that scientists concerned about human influence on the biosphere need to take a deeper look at how altering the dynamics of a population — for example, by removing large members of a species through overfishing — can have measurable consequences, said Rice ecologist Volker Rudolf.

The results, they said, show that changes to an ecosystem appear long before a species disappears entirely.
