The Causes and Consequences of Ant Invasions
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.
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.

Thrice Out of Africa: Ancient and Recent Expansions of the Honey Bee, Apis mellifera
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
Behavioral and Genetic Differentiation Between Native and Introduced Populations of the Argentine Ant
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
Insights into social insects from the genome of the honeybee Apis mellifera
The genome sequence of the honeybee Apis mellifera is reported, suggesting a novel African origin for the species A. melliferA and insights into whether Africanized bees spread throughout the New World via hybridization or displacement. Expand
The Colony Structure and Population Biology of Invasive Ants
The population biology of invasive ants is reviewed, focusing on the role of sociality and colony structure in their success, and different hypotheses that have been proposed for the observed transitions in social structure of the two most well-studied ant invaders. Expand
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
The evolutionary consequences of biological invasions
The evolutionary causes and consequences of biological invasions are examined to examine the mechanisms of success of some invasive species and the growing availability of genomic tools will permit the identification of underlying genetic causes of invasive success. Expand
Inclusive fitness theory and eusociality
It is argued that inclusive fitness theory has been of little value in explained the natural world, and that it has led to negligible progress in explaining the evolution of eusociality, but these arguments are based upon a misunderstanding of evolutionary theory and a misrepresentation of the empirical literature. Expand
Draft genome of the globally widespread and invasive Argentine ant (Linepithema humile)
The draft genome sequence of a particularly widespread and well-studied species, the invasive Argentine ant, is reported, which was accomplished using a combination of 454 and Illumina sequencing and community-based funding rather than federal grant support. Expand
