Abstract
Environmental challenges shape the evolution of animal behavior and morphology. For wingless terrestrial invertebrates like ants, pools of water on the forest floor are particularly dangerous. Here we show that ants can overcome this obstacle using a modified gait to transverse the water surface. We compared the locomotor morphology and swimming performance of two arboreal ant species that are common in Kentucky (Camponotus pennsylvanicus and Formica subsericea). We defined performance as speed …
Kentucky Lake: An Opportunity For Long Term Monitoring Of Fish Communities, Bradley Hartman
Kentucky Lake: An Opportunity For Long Term Monitoring Of Fish Communities, Bradley Hartman
Scholars Week
Global aquatic ecosystems are impacted by a variety of mechanisms including habitat destruction, fish overharvest, and the introduction of invasive species. Long term monitoring of an ecosystem’s fish community, along with abiotic and biotic factors that influence the fish community, is crucial in establishing effective management strategies. Currently, numerous monitoring programs exist across the United States. However, a long term monitoring program of non-game and non-commercial fish community dynamics has not been established within Kentucky Lake in Western Kentucky. Preliminary sampling of the Kentucky Lake fish community was performed using boat electroshocking and surface trawling. Four embayments within Kentucky Lake …
