Santa Cruz Island Reserve

03 Jun, 05 AM - 13 Jun, 02 AM

The invasion and continued expansion of the Argentine ant, Linepithema humile, on Santa Cruz Island (SCI) threatens this island's unique biota. Our proposed research on SCI has four main objectives: (1) to assess qualitative and quantitative impacts of L. humile on native ant assemblages, (2) to document the ecological effects of this invasion on other arthropod taxa, some of which form an important component of the diet of endemic island vertebrates, (3) to augment existing knowledge of terrestrial invertebrate species on SCI, and (4) to measure the impact of Argentine ants on the plant-pollinator interactions and energetics of Calystegia macrostegia. The anticipated results will inform the long-term management goals of The Nature Conservancy and the National Park Service by identifying and quantifying the conservation gains of eradicating invasive L. humile populations across the Channel Islands. These results will also form the basis of a published analysis of the terrestrial invertebrates of SCI and how they may be affected by the continued expansion of the Argentine ant.
