The study of population genetics has shaped the field of phylogeography and provided insights into the biotic and abiotic mechanisms that influence gene flow and adaptation. Changes at the DNA sequence level are thought to occur when populations are isolated by physical barriers or strong environmental gradients that limit gene flow, allowing divergence over several generations unless strong selection accelerates …
Biology Department CalendarPentastomes, or tongue worms, are parasitic crustaceans that primarily infect the respiratory tracts of their hosts. These parasites commonly infect vertebrates, including reptiles, mammals, and amphibians, with snakes most often serving as their definitive hosts. The introduction of the non-native pentastome Raillietiella orientalis to South Florida has led to its rapid geographical expansion and invasion of naïve host species, causing …
