Large herbivores play unique ecological roles and are disproportionately imperiled by
human activity. As many wild populations dwindle towards extinction, and as interest grows …

Fire shapes the distribution of savanna and forest through complex interactions involving
climate, resources and species traits. Based on data from central Brazil, we propose that …

They may influence us as individuals by their encouragement and guidance; they may affect
their community through their untiring commitment to service and the greater good; or they …

Trophic cascades—the top-down regulation of ecosystems by predators—are an essential
aspect of ecosystem function and well-being. Trophic cascades are often drastically …

BACKGROUND Modern advances in remote-sensing technology are providing
unprecedented opportunities to accurately measure the global distribution of carbon held in …

We aimed to identify the limits of savanna across Africa, Australia and South America. We
based our investigation on the rich history of hypotheses previously examined: that the limits …

Conventional approaches to natural resource management are increasingly challenged by
environmental problems that are embedded in highly complex systems with profound …

The determinants of fire-driven changes in soil organic carbon (SOC) across broad
environmental gradients remains unclear, especially in global drylands. Here we combined …

The extirpation of native wildlife species and widespread establishment of livestock farming
has dramatically distorted large mammal herbivore communities across the globe …

Tree cover is a fundamental structural characteristic and driver of ecosystem processes in
terrestrial ecosystems, and trees are a major global carbon (C) sink. Fire and herbivores …
