Movement patterns and gene flow of Agalychnis callydrias:

(Auburn University). This collaboration combines molecular and field-based methods to understand daily movement patterns and to detect the spatial scale at which swamps populations are genetically connected and isolated. Matt is using radio-telemetry to track the daily movement patterns of the large swamp-breeding hylid, A. callidryas and we will utilize microsatellites to characterize population structure within and among swamps at La Selva Biological Station and La Reserva Tirmbina.

Kelly Zamudio and Peter Rosenbaum (SUNY Oswego):
The bog turtle is arguably North Americas smallest and rarest turtle. They are a long-lived, secretive, somewhat fossorial, and cryptic species that live in highly specialized wetlands including bogs, fens and wet meadows. Over the past 20 years, this species has experienced at least a 50 percent decline due to loss, degradation and fragmentation of its wetland habitats, toxic and organic pollution, and due to illegal collection. We conducted a genetic assessment of bog turtles to understand the history of colonization throughout the range of this species, the degree of differentiation among populations, and the historical and current gene flow among populations.

Andres and Robert have helped me immeasurably with logistics and field collection in Costa Rica, and Cachi graciously provided me with access to the UCR herp collections.
