1. Dialing back extinction rates
A widely-used, indirect method of estimating how quickly species will vanish based on how much of their habitat is lost likely overestimates actual extinction rates.

2. Energy flux in water and on land
Increasing the flow of energy through ecosystems makes them less stable by increasing the ratio of consumers to resources available. And it turns out that watery ecosystems are ...
