Invading organisms may spread through local movements (giving rise to a diffusion-like
process) and by long-distance jumps, which are often human-mediated. The local spread of …

We investigated the roles of habitat fragmentation and the invasion of an exotic species on
the structure of ground‐foraging ant communities in 40 scrub habitat fragments in coastal …

Many museums and academic institutions maintain first-rate collections of biological materials,
ranging from preserved whole organisms to DNA libraries and cell lines. These biological …

Despite the innumerable ecological problems and large economic costs associated with
biological invasions, the proximate causes of invasion success are often poorly understood. …

A major challenge of invasion biology is the development of a predictive framework that prevents
new invasions. This is inherently difficult because different biological characteristics are …

In this paper, we examine the hypothesis that reduced intraspecific aggression underlies the
competitive prowess of Argentine ants in their introduced range. Specifically, we test three …

▪ Abstract Invasions by non-native ants are an ecologically destructive phenomenon affecting
both continental and island ecosystems throughout the world. Invasive ants often become …

Despite the severe ecological and economic damage caused by introduced species, factors
that allow invaders to become successful often remain elusive. Of invasive taxa, ants are …

We characterized Apis mellifera in both native and introduced ranges using 1136 single-nucleotide
polymorphisms genotyped in 341 individuals. Our results indicate that A. mellifera …
