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.

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.

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.

On the Evolution and Adaptive Significance of Postnatal Growth Rates in the Terrestrial Vertebrates

  • Biology, Environmental Science
    The Quarterly Review of Biology
  • 1 September 1978
TLDR
The results of this analysis support the notion that growth rate is adapted to certain features of an animal's environment, which will be altered in an empirically appropriate direction with changes in these environmental parameters.

A General Explanation for Insular Body Size Trends in Terrestrial Vertebrates
TLDR
The insular body size trends for different vertebrate families are compared and optimum body size models that use as the optimization criterion the net energy gained by an organism over a given time period are examined.

Perturbation Experiments in Community Ecology: Theory and Practice
We analyze perturbation experiments performed on real and idealized ecological com- munities. A community may be considered as a black box in the sense that the individual species grow and interact…

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.

Invasion resistance arises in strongly interacting species-rich model competition communities.

  • Environmental Science
    Proceedings of the National Academy of Sciences…
  • 1 December 1990
TLDR
A logical framework for an island-biogeographic theory in which species turnover is low even in the face of persistent invasions and for the protection of fragile native species from invading exotics is provided.

Interspecific Competition, Environmental Gradients, Gene Flow, and the Coevolution of Species' Borders
  • T. Case, M. Taper
  • Environmental Science, Biology
    The American Naturalist
  • 1 May 2000
TLDR
This model includes interspecific competition and the frequency‐dependent selection that it generates, as well as stabilizing selection on a quantitative character, and simultaneously addresses the evolution of character displacement and species borders and reproduces the Kirkpatrick and Barton result that limited ranges can be produced with sufficiently steep environmental gradients and strong dispersal.

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.
