Morphological Correlates Of Auditory Sensitivity In The Inner Ear Of Two Species Of Invasive Carp, Tyler Patty
Morphological Correlates Of Auditory Sensitivity In The Inner Ear Of Two Species Of Invasive Carp, Tyler Patty
Mahurin Honors College Capstone Experience/Thesis Projects
Silver (Hypopthalmichthys molitrix) and bighead (H. nobilis) carp, are invasive species that have negative impacts upon ecosystems. H. molitrix is known to jump completely out of the water in response to broadband sounds, however, this is not observed in H. nobilis. Preliminary experiments reveal that sounds can be used to modify the behavior of carps. Thus, understanding the hearing abilities of these species is important in order to design appropriate acoustical deterrents. Fish heads were preserved in 4% paraformaldehyde and the inner ears dissected and photographed under a light microscope in order to describe the …
An Investigation On The Cover Preference Of The Mountain Madtom (Noturus Eleutherus), Mariah Slaughter
An Investigation On The Cover Preference Of The Mountain Madtom (Noturus Eleutherus), Mariah Slaughter
Mahurin Honors College Capstone Experience/Thesis Projects
Madtom catfish, members of the genus Noturus, are common in the waters of the Southeastern US. A previous study observed that madtoms in the Green River, Kentucky, preferred to shelter within old mussel shells compared to under or next to rocks. A laboratory study on the Carolina Madtom (Noturus furiosus), found that they did not utilize mussel shells and preferred rocks as cover. I conducted a similar laboratory study to determine which cover options the Mountain Madtoms (Noturus eleutherus) prefer. Cover preference was determined by offering the madtoms shelter options (rocks or mussel shells) in …
Effects Of Supplemental Whole Cottonseed On Weaned Calf Production, Zachary Debord
Effects Of Supplemental Whole Cottonseed On Weaned Calf Production, Zachary Debord
Mahurin Honors College Capstone Experience/Thesis Projects
This study compared the effect of supplemental whole cottonseed in a weaned calf ration on cattle productivity. Feed is the main cost for livestock production. Whole cottonseed supplementation may increase production and reduce the cost of gain for the ration. During the study, 18 beef calves were weaned and split into two groups and fed, with and without WCS, for 50 days to determine the effect of supplemental whole cottonseed. Productivity was determined by measuring average daily gains for each group and comparing cost of gain for each ration. It was determined that WCS did increase productivity of weaned calves …
