Changes In The Zooplankton Community In Barren River Lake (South Central Ky) Between 2008 And 2020, Laurel Philpott
Mahurin Honors College Capstone Experience/Thesis Projects
Zooplankton are small aquatic animals that serve an important role in transferring energy from phytoplankton to higher trophic levels. The zooplankton community composition in Barren River Lake from 2008 and 2020 was compared. A field study was conducted to not only describe the seasonal population dynamics of zooplankton in Barren River Lake, but also to determine if an invasive zooplankton, Daphnia lumholtzi, was present. While D. lumholtzi was found throughout Barren River Lake in 2008, it was absent from both resampled sites in 2019 and 2020. This, along with erratic patterns of emergence in several other zooplankton species, indicates …

Dietary Overlap Of Native White Bass And Introduced Yellow Bass In Barren River, Micaela L. Montgomery
Mahurin Honors College Capstone Experience/Thesis Projects
In the Barren River Lake of south central Kentucky, native white bass, Morone chrysops, has experienced a decline in population after the introduction of yellow bass, Morone mississippiensis. These species are competing for resources due to an overlapping diet, likely contributing to the decline of the white bass. To explore this hypothesis, I examined the stomach contents and otoliths of white and yellow bass caught during their spawning time in spring 2012. There were 40 yellow bass and 128 white bass collected in Barren River upstream of Barren River Lake. Analysis of stomach contents revealed that both white and …
