Résumé :
|
Biodiversity declines are ubiquitous. Yet, their impacts on ecosystems or the services ecosystems provide to humans are poorly understood because it is hard to measure the effect of biodiversity declines separately from other changes that are spatially or temporally correlated with biodiversity patterns. This limitation in understanding the impacts of biodiversity declines stymies addressing their causes through policy. One promising approach is to exploit natural experiments that provide variation in biodiversity that is otherwise unrelated to the outcomes to estimate causal impacts of biodiversity declines. On page 1062 of this issue, Frank (1) uses such a natural experiment to evaluate not only the regulating effect of biodiversity, but also the consequences of technological substitutes in response to biodiversity declines. Using white-nose syndrome (WNS), a lethal bat disease, as a shock to bat populations, he estimates causal effects of bat declines on agricultural pest control and infant health outcomes.
