African savannas support an iconic fauna, but they are undergoing large‐scale population
declines and extinctions of large (> 5 kg) mammals. Long‐term, controlled, replicated …

Edge effects are one of the most extensively studied ecological phenomena of the past 100
years. Despite the still-common perception that edge effects are overly complex and …

Large mammalian herbivores (megafauna) have experienced extinctions and declines since
prehistory. Introduced megafauna have partly counteracted these losses yet are thought to …

On rangelands worldwide, cattle interact with many forms of biodiversity, most obviously with
vegetation and other large herbivores. Since 1995, we have been manipulating the …

Ecosystem engineering is an innovative concept that recognizes that organisms impact their
environment, and that these changes can be detected over time. Thus, additional datasets …

The African savannah ecosystem is populated by nomadic pastoralists who herd livestock in
the day and corral them at night in temporary enclosures, called bomas, to protect them. The …

This essay examines three central components of extensive livestock production—herd
composition, grazing/pasture management, and rangeland tenure. In all of these areas …

In eastern Africa, ecologists have found that when mobile pastoralists abandon their
temporary encampments, the accumulation of burned animal dung, wood, and other organic …

Herbivory by both grazing and browsing ungulates shapes the structure and functioning of
terrestrial ecosystems worldwide, and both types of herbivory have been implicated in major …

Pastoralism and agriculture have affected rangeland ecosystems over the past millennia,
including many ecosystems that are currently protected as reserves. However, the legacy of …
