Biogeographic effects of red fire ant invasion
- N. Gotelli, A. Arnett
- Environmental Science
- 1 July 2000
The results suggest that the effects of S. invicta on native ant communities are pervasive: not only does the presence of the red imported fire ant reduce species density at local scales, it alters the co-occurrence patterns of surviving species at a biogeographic scale.
GEOGRAPHIC VARIATION IN LIFE‐HISTORY TRAITS OF THE ANT LION, MYRMELEON IMMACULATUS: EVOLUTIONARY IMPLICATIONS OF BERGMANN'S RULE

This study provides the first example of countergradient selection causing Bergmann's rule in an ectotherm, and suggests that variation in food availability, not temperature, may account for differences in growth and body size of northern and southern ant lions.
Invasiveness of Some Biological Control Insects and Adequacy of Their Ecological Risk Assessment and Regulation

Abstract: The problem of invasive species has reignited interest in biological control as a management tool. Classical biological control involves deliberate release of exotic natural enemies into…

It is suggested that regional differences in foraging behavior may contribute to latitudinal gradients in life history strategies seen in this insect.
Preference of antlion and wormlion larvae (Neuroptera: Myrmeleontidae; Diptera: Vermileonidae) for substrates according to substrate particle sizes

The hypothesis that neuropteran larvae prefer specific substrates for pitbuilding or ambushing prey, and that this - in combination with other abiotic and biotic factors - may drive selection of appropriate habitats is supported.
Bergmann's rule in the ant lion Myrmeleon immaculatus DeGeer (Neuroptera: Myrmeleontidae): geographic variation in body size and heterozygosity
- A. Arnett, N. Gotelli
- Environmental Science, Biology
- 1 March 1999
Aim Geographic variation in body size and heterozygosity were surveyed for discrete populations of the ant lion, Myrmeleon immaculatus DeGeer, collected from the central and northeastern United…
Evaluation of ecological risk to populations of a threatened plant from an invasive biocontrol insect
The results indicate that the weevil poses a serious quantitative, demographic risk to the threatened C. pitcheri and supports the suggestion that ecological data can be used to improve the quantification of risk to native nontarget plant populations within the potential physiological host range of a biological control insect.
