As a second year PhD student, Ida is investigating the ways in which communities reassemble in the face of ecological disturbance. Ida is using an ongoing Argentine ant (Linepithema humile) eradication program on Santa Cruz Island, California as an arena to measure both structural and functional components of native ant resiliency to Argentine ant removal. Ida is also interested generally in southern California regional ant diversity. She is currently examining patterns of evolutionary diversification of carpenter ants (genus: Camponotus) on the California Channel Islands using phylogenetics, as well as inventorying ant species associated with the archipelago.

Ida’s previous projects include using nitrogen isotopes to examine ant-aphid interactions on non-native fennel, studying the impacts of the Argentine ant on island morning glory (Calystegia macrostegia), and inventorying arthropods associated with island scrub oak (Quercus pacifica) habitats. During her undergraduate career, Ida conducted a study of the phylogeography of Aphaenogaster occidentalis (family: Formicidae) across the west coast using DNA barcoding and worked on a study of the competitive impacts of yellowjackets (Vespula pennsylvanica) on plant pollinator mutualisms on the big island of Hawai’i.
