Fish Community Trends In The Greenup Pool, Ohio River, Nathaniel Kingsley Fleshman Jan 2022

Fish Community Trends In The Greenup Pool, Ohio River, Nathaniel Kingsley Fleshman

Theses, Dissertations and Capstones

Bighead carp (Hypophthalmichthys nobilis) and silver carp (H. molitrix), collectively referred to as Asian carps, are invasive species that may negatively affect native species through plankton resource exploitation mechanisms. Bighead and silver carp escaped into the Mississippi River basin in the early 1970s and have been steadily migrating upstream. The Greenup Pool lies upstream of the current known invasion of Asian carp in the Ohio River. The Ohio River Valley Water Sanitation Commission (ORSANCO) has conducted probabilistic electrofishing community surveys in the Greenup Pool since 2006 on a five-year cycle. The objective of this study was …


Diversity Of The Ohio River Bacterial Communities Using Next-Generation Sequencing Techniques, Emily Michele Anneken Jan 2012

Diversity Of The Ohio River Bacterial Communities Using Next-Generation Sequencing Techniques, Emily Michele Anneken

Theses, Dissertations and Capstones

The ability to sequence bacterial genetic material directly from environmental samples has unlocked the field of metagenomics. Next-generation sequencing techniques, such as pyrosequencing, have been instrumental in providing knowledge about bacterial communities. This study focused on identifying the bacterial diversity of the Ohio River via pyrosequencing and compared the diversity of cultivable bacteria versus the entire river community. To ensure the maximum number of cultivable bacteria was obtained, cultures were grown on nonselective media and incubated at river temperature. Bacterial DNA was extracted, sequenced, and classified. The dominant phyla for the Ohio River included Cyanobacteria (38-66% of the total), Actinobacteria …


Reproductive Biology Of The Bowfin, Amia Calva Linnaeus, From The Green Bottom Wildlife Management Area, Cabell County, West Virginia, Katie Lee Mcginn Daniels Jan 1993

Reproductive Biology Of The Bowfin, Amia Calva Linnaeus, From The Green Bottom Wildlife Management Area, Cabell County, West Virginia, Katie Lee Mcginn Daniels

Theses, Dissertations and Capstones

The bowfin, Amia calva Linnaeus, is the only extant species of the family Amiidae. The Green Bottom Wildlife Management Area (GBWMA) is the home of the only known reproducing bowfin population in the state of West Virginia. The GBWMA (38°35' 35" N, 82°14' 55" W) is located along the Ohio River 26 km northeast of Huntington, West Virginia. The area (ca. 364 ha) contains a valuable wetland habitat (ca. 57 ha) in the southwestern portion of the state. A study of the reproductive biology of the bowfin became important when the u.s. Army Corps of Engineers proposed a habitat modification …


The Naiads (Mollusca: Unionidae) From Two Prehistoric Sites Along The Ohio River, Mason County, West Virginia, Beverly Dawn Spurlock Jan 1981

The Naiads (Mollusca: Unionidae) From Two Prehistoric Sites Along The Ohio River, Mason County, West Virginia, Beverly Dawn Spurlock

Theses, Dissertations and Capstones

Archeological naiad valves representing 29 species were recovered from two Late Prehistoric Indian villages along the Ohio River, Mason County, West Virginia. Surface collections and limited excavation provided a total of 1,599 identifiable valves and valve fragments. Dif­ferences in species compositions and relative abundances between the two middens were noted. Samples from the Rolf Lee Farm Site (46MS51) contained 28 species while the Lewis-Old Town Farm Site (46MS57) produced only 23 species. Comparisons were made with other nearby prehistoric shell deposits and also with more recent twentieth century collections from this reach of the river. Nine of the archeological species …
