Effects Of Natural History On Osmoregulatory Behaviors In Two Stream-Dwelling Frogs (Pseudacris Cadaverina And P. Regilla), Heidy Lorena Contreras Jan 2007

Effects Of Natural History On Osmoregulatory Behaviors In Two Stream-Dwelling Frogs (Pseudacris Cadaverina And P. Regilla), Heidy Lorena Contreras

Theses Digitization Project

Differences in osmoregulatory behaviors were studied in two stream-dwelling tree frogs (Pseudacris cadaverina and P. regilla) with different natural histories. This study supports the idea that the natural history of a species has a strong effect on behavior associated with osmoregulation.


A Geographically Constrained Molecular Phylogeny Of Panamanian Aechmea Species (Bromeliaceae, Subfamily Bromelioideae), Keri Renee Maher Jan 2007

A Geographically Constrained Molecular Phylogeny Of Panamanian Aechmea Species (Bromeliaceae, Subfamily Bromelioideae), Keri Renee Maher

Theses Digitization Project

This study lends strong support to the idea that members of Bromeliaceae have undergone a recent adaptive radiation, and therefore show that, at least in part, diversity in the tropics is due to a fast speciation rate and that the tropics can be a "cradle" for new diversification and exploitation of varying ecological niches through the diversification of ecophysiological traits within a lineage.
