Change in dominance determines herbivore effects on plant biodiversity
2018
Herbivores alter plant biodiversity (species richness) in many of the world’s ecosystems, but the magnitude and the direction of herbivore effects on biodiversity vary widely within and among ecosystems. One current theory predicts that herbivores enhance plant biodiversity at high productivity but have the opposite effect at low productivity. Yet, empirical support for the importance of site productivity as a mediator of these herbivore impacts is equivocal. Here, we synthesize data from 252 large-herbivore exclusion studies, spanning a 20-fold range in site productivity, to test an alternative hypothesis—that herbivore-induced changes in the competitive environment determine the response …

The zoogeographical domains: a new conservation target at global scale
2018
Zooregions are classifications of the Earth’s surface based on characteristic species assemblages. Consequently, zooregions reflect how ecological, evolutionary, and historical processes have been acting over millions of years, arguably making them the largest entities to conserve the uniqueness of the species assemblages on Earth. Because species are distributed along zooregions heterogeneously, to conserve zooregions adequately, we need to protect their characteristic areas (transition, core or endemic areas), what we call the zoogeographical domains. Here we propose a method to characterize the zoogeographical domains basing on four metrics, which are independently used in macroecologica…
