Evaluation Of Invasive Avifauna Management Strategies In North America, Christopher L. Castillo
Evaluation Of Invasive Avifauna Management Strategies In North America, Christopher L. Castillo
Graduate Review
Human action has long been the cause of species introductions into new ecosystems (Lodge 1993). Now, these non-native species are a major global problem both ecologically and economically (Bled et al. 2011). Invasive species can alter habitats, decrease biodiversity, damage human settlements, and destroy agriculture (Townsend Peterson and Vieglais 2001; Kumschick and Nentwig 2010). The United States has been particularly affected by invasive introductions, a multitude of which have been avian species. Various management techniques have been implemented in order to control problem bird populations, however often times these methods are used with a ‘trial and error’ strategy. This review …
Behavioral Choices Of Apple Snails, Pomacea Maculata, Under Varied Chemical Landscapes, Andrea Adams
Behavioral Choices Of Apple Snails, Pomacea Maculata, Under Varied Chemical Landscapes, Andrea Adams
Theses
Habitat choice is a critical behavior for organisms to successfully survive and reproduce. These choices are dictated by available environmental information about potential predation risks or food patches that form the organism’s sensory landscape. This study specifically focused on the behavioral choices of two invasive apple snail (Pomacea maculata) populations exposed to varying predation threats. We collected snails from Florida and Alabama which were used in laboratory experiments with varied sensory landscapes. Trials consisted of controls with no cues (FL: n = 7, AL: n= 7), an attractive treatment with introduced food cues (FL: n = 4, AL: …
Changes In The Zooplankton Community In Barren River Lake (South Central Ky) Between 2008 And 2020, Laurel Philpott
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 …
