Mitochondrial Dna Suggests Stonerollers (Campostoma Anomalum) From Upper Shavers Fork Have Strong Genetic Similarities With The Recently Identified New River Form, Michael G. Sovic, Kody F. Kuehnl

Scholarship Forum 2013

A recent analysis of cytochrome b sequence data suggested the presence of two distinct lineages of stoneroller (Campostoma anomalum) in West Virginia: one form that occurs throughout most waters of the Ohio and Potomac River basins, and a second that is restricted to the New River basin.

In Michael Sovic and Dr. Kody Kuehnl's study, cytochrome b data are presented for individuals sampled from the upper reaches of Shavers Fork, a tributary of the Cheat River that is geographically proximate to, but not within the New River drainage. Haplotypes observed in the individuals from Shavers Fork are most similar to …

Freshwater Mussels As Biological Indicators, Vera Kazaniwskyj, Y. Zhang, G. Thomas Watters, Kody F. Kuehnl, Barbara A. Wolfe

Scholarship Forum 2013

Viral hemorrhagic septicemia virus (VHSV) is a devastating rhabdovirus affecting freshwater fishes worldwide. In 2005, a new genotype of VHSV (IVb) was discovered in Lake St. Clair and has consequently spread throughout the Laurentian Great Lakes. While it is widely known that freshwater fishes are hosts and transmitters of VHSV, little is known about the ability of invertebrates to take up and carry the virus. Our (Vera Kazaniwskyj, Y. Zhang, G. Thomas Watters, Dr. Kody Kuehnl, and Barbara Wolfe) objective in this study was to investigate the ability of freshwater mussels to accumulate and transmit VHSV by using two commonly …

Molecular Assessment Of Three Reproducing Populations Of The Clubshell Mussel (Pleurobema Clava) Reveals Historic Hybridization With Pleurobema Sintoxia, Kody F. Kuehnl, Michael G. Sovic

Scholarship Forum 2013

The clubshell (Pleurobema clava) is a federally endangered species of freshwater mussel endemic to Ohio that is currently found in fewer than ten river systems in the United States (>85% range reduction). Two of the USFWS’s (1993) recovery goals are to establish ten viable populations and maintain any existing genetic viability. In order to recover the clubshell, conservation efforts including translocation and captive propagation have been used to augment existing populations. In order to maintain the genetic diversity and population level specificity, a molecular assessment is needed. In this study, we generated nuclear microsatellite data and mitochondrial (mtDNA) sequence …

Effects Of 17Β-Estradiol Exposure On Gamete Development And Viability In Freshwater Unionids, David Sovic, Kody F. Kuehnl, Roman Lanno, G. Thomas Watters

Scholarship Forum 2013

Evidence of a functional role for vertebrate steroids has been demonstrated in a number of invertebrate species, including molluscs. This knowledge has generated interest into the possibility of invertebrate endocrine disruption due to exposure to both exogenous steroid hormones and xenobiotics which can mimic the action of these compounds. Exposure to the natural vertebrate estrogen, 17β-estradiol (E2), for example, has been shown to induce accelerated gamete development in multiple mollusc species. Little information exists, however, for freshwater mussels, a group of exceptional conservation interest.

Here, Daniel Sovic, Raoman Lanno, Dr. Kody Kuehnl, and G. Thomas Watters report the findings of …
