Argentine Ant Invasions in Southern California: Causes and Consequences of Ecological Success
Presented by: David A. Holway, Ph.D., Professor, University of California at San Diego,
Section of Ecology, Behavior & Evolution, Division of Biological Sciences
A widespread, abundant, and damaging invasive species, the Argentine ant may be unique among introduced species in achieving dual status as an urban pest and an ecosystem invader.
In Southern California, L. humile readily invades scrub and riparian habitats where it displaces native ant species through a combination of competition and predation. The homogenization of ant assemblages following invasion by L. humile likely affects a wide range of organisms, yet the ecological effects of this widespread invasion remain incompletely understood.
This seminar will focus on recent work that investigates why the Argentine ant invades some habitats and not others and that clarifies what happens to other organisms after the Argentine ant becomes established.
This and all other lectures in the Seminar Series will be held at the Beckman Center Meeting Room, 11:30 a.m. to 12:30 p.m. (next to the San Diego Zoo Safari Park in Escondido) unless otherwise noted.
