The Causes and Consequences of Ant Invasions
TLDR
Experimental studies and research focused on the native range ecology of invasive ants will be especially valuable contributions to this field of study. Expand
Reduced genetic variation and the success of an invasive species.
TLDR
Using microsatellite markers, it is shown that a population bottleneck has reduced the genetic diversity of introduced populations, and this loss is associated with reduced intraspecific aggression among spatially separate nests, and leads to the formation of interspecifically dominant supercolonies. Expand
Patterns of spread in biological invasions dominated by long-distance jump dispersal: Insights from Argentine ants.
TLDR
The invasion history of the Argentine ant (Linepithema humile), a widespread invasive species, is reconstructed at three spatial scales using a combination of literature review, museum records, and personal surveys to improve the predictive power of future modeling efforts. Expand
EFFECTS OF FRAGMENTATION AND INVASION ON NATIVE ANT COMMUNITIES IN COASTAL SOUTHERN CALIFORNIA
TLDR
The surveys suggest that the Argentine ant is widespread in fragmented coastal scrub habitats in southern California and strongly affects native ant communities. Expand
Thrice Out of Africa: Ancient and Recent Expansions of the Honey Bee, Apis mellifera
TLDR
The results indicate that A. mellifera originated in Africa and expanded into Eurasia at least twice, resulting in populations in eastern and western Europe that are geographically close but genetically distant. Expand
ROLE OF ABIOTIC FACTORS IN GOVERNING SUSCEPTIBILITY TO INVASION: A TEST WITH ARGENTINE ANTS
TLDR
Experimental data demonstrate how the abiotic environment impinges on both colony-level activity and colony growth in the Argentine ant and provide a general explanation for the patterns observed at the community level. Expand
Arthropods in urban habitat fragments in southern California: Area, age, and edge effects
TLDR
Although higher trophic levels are often considered to be more sensitive to fragmentation, two groups of arthropod predators, spiders and carabid beetles, increased in abundance in older fragments and there was a strong seasonal variation in abundance and diversity in most orders. Expand
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
Genetic and genomic analyses of the division of labour in insect societies
TLDR
Different forms of division of labour, in lineages in which eusociality has arisen independently, have evolved through changes in the regulation of highly conserved molecular pathways associated with several basic life-history traits, including nutrition, metabolism and reproduction. Expand
Behavioral and Genetic Differentiation Between Native and Introduced Populations of the Argentine Ant
TLDR
Results identify a possible mechanism for the widespread success of the Argentine ant in its introduced range by comparing the genetic diversity, behavior, and ecology of Argentine ants in their native range to introduced populations. Expand
