Food webs can be conceptualized as being powered by energy derived from living and dead vegetation, respectively. Most food web research has focused on “green food webs” which begin with the consumption of living vegetation by herbivores. However, “brown food webs” which stem from the consumption of senescent vegetation by detritivores are also an...

Eucalypts have a widespread global distribution owing to their popularity for agroforestry and as environmental plantings. Despite an abundance of site‐specific evidence that eucalypts modify soils and soil processes, we lack a quantitative synthesis of their overall effects at the global scale. This limits our capacity to assess the likely impacts...

In desert ecosystems, some argue that primary productivity controls vertebrate populations while others contend that predators' top-down effects are under-appreciated. While seldom used to explain population dynamics in desert environments, the exploitation ecosystems hypothesis (EEH) unites bottom-up and top-down processes by conceptualizing how t...

Typically, termites are treated as a single guild, which ignores important internal diversity, including diverse feeding and nesting traits. These termite traits are crucial for both ecosystem‐level fluxes and trophic webs, with implications for vertebrate species. Despite their ecological importance, the large‐scale distribution of termite feeding...

Few restoration studies consider soil invertebrates such as termites although these are present throughout many ecosystems worldwide and provide a range of ecosystem services as soil engineers. The few studies that do consider the recovery of termites after human-induced disturbance are geographically concentrated in Africa and South America and in...

The 5500 km long dingo barrier fence (DBF) is a boundary at which the goal of dingo control programs shifts from management to elimination. Since 1980 ecologists have used the discrepancies in dingo densities across the DBF to study the ecological role of Australia’s largest terrestrial predator. We used drone imagery, ground based shrub and tree c...
