Reduced genetic variation and the success of an invasive species.
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 among the mostExpand

Patterns of spread in biological invasions dominated by long-distance jump dispersal: Insights from Argentine ants.
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 invading organisms hasExpand

EFFECTS OF FRAGMENTATION AND INVASION ON NATIVE ANT COMMUNITIES IN COASTAL SOUTHERN CALIFORNIA
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 southernExpand

Avian assemblages along a gradient of urbanization in a highly fragmented landscape
Abstract Our goal was to evaluate how avian assemblages varied along a gradient of urbanization in the highly fragmented landscape of coastal southern California. We measured species richness andExpand

Arthropods in urban habitat fragments in southern California: Area, age, and edge effects
The distribution of non-ant arthropods was examined in 40 urban habitat fragments in coastal San Diego County, California, USA, to look for effects of fragmen- tation, proximity to developed edge,Expand

Trophic ecology of invasive Argentine ants in their native and introduced ranges
Although the ecological effects of invasions often become obvious soon after introduced species become established, more gradual effects may take years to manifest and can thus require long-term dataExpand

Measuring the trophic ecology of ants using stable isotopes
Abstract.Ants are prominent components of most terrestrial arthropod food webs, yet due to their highly variable diet, the role ants play in arthropod communities can be difficult to resolve. StableExpand

Geographical potential of Argentine ants (Linepithema humile Mayr) in the face of global climate change
Determining the spread and potential geographical distribution of invasive species is integral to making invasion biology a predictive science. We assembled a dataset of over 1000 occurrences of theExpand

The Value of Museum Collections for Research and Society
Abstract Many museums and academic institutions maintain first-rate collections of biological materials, ranging from preserved whole organisms to DNA libraries and cell lines. These biologicalExpand

Multifunctionality and mechanical origins: Ballistic jaw propulsion in trap-jaw ants
Extreme animal movements are usually associated with a single, high-performance behavior. However, the remarkably rapid mandible strikes of the trap-jaw ant, Odontomachus bauri, can yield multipleExpand
