Knowledge on the distribution and abundance of organisms is fundamental to
understanding their roles within ecosystems and their ecological importance for other taxa …

Most of the described and probably undescribed species on Earth are insects. Global
models of species diversity rarely focus on insects and none attempt to address unknown …

Environmental stressors and changes in land use have led to rapid and dramatic species
losses. As such, we need effective monitoring programs that alert us not only to biodiversity …

In between Earth's poles, ants exert impacts on other biota that are unmatched by most
animal clades. Through their interactions with animals, plants, fungi and microbes, ants have …

Habitat transformation and disturbance are significant threats to biodiversity conservation
and ecosystem function. Disturbance is generally defined as any event that removes …

We examined species density gradients of ants of New England in 22 ombrotrophic bogs
and their surrounding forests. We tested the hypothesis that species density was correlated …

One of the many goals of invasion biology is the identification of factors that determine
whether a species will establish successfully in a new environment and that predict whether …

Army ants form nomadic insect colonies whose chief food is other social insects. Here we
compare the rate of army ant raids with the average density of their potential prey from 28 …

Ants are key indicators of ecological change, but few studies have investigated how ant
assemblages respond to dramatic changes in vegetation structure in temperate forests …

Ants are among the most diverse, abundant and ecologically significant organisms on earth.
Although their species richness appears to be greatest in the New World tropics, global …
