Dr. Larkin's research focuses on the molecular and chemical ecology of native plant species, in particular their interaction with their environment and response to habitat fragmentation. It includes both specific events, such as the effect of temperature on the expression of allelic variants of a single enzyme (Granule Bound Starch Synthase) and broader events, such as the genetic relationships among populations in fragmented habitats. Some of the plant species studied include rice (Oryza sativa L.), shoalgrass (Halodule beaudettei), turtlegrass (Thalassia testudinum) bundleflower (Desmanthus virgatus) and Kleberg's bluestem (Dichanthium annulatum). His research involves characterization of genomic and organellar DNA variation and expression through DNA sequencing, Amplified restriction Fragment Length Polymorphism (AFLP), Random Amplification of Polymorphic DNA (RAPD), and Microsatellite (STR) analysis. Field, molecular and environmental data are used to examine how plants respond and, eventually, adapt to their environments.
