Assessing Populations Of Eastern Brook Trout (Salvelinus Fontinalis) Above And Below Waterfalls In Mountain Streams Of Virginia, Hannah Eisemann Macmillan
Assessing Populations Of Eastern Brook Trout (Salvelinus Fontinalis) Above And Below Waterfalls In Mountain Streams Of Virginia, Hannah Eisemann Macmillan
Masters Theses, 2010-2019
Anthropogenically driven factors, such as increasing temperature and sediment in valley streams, acidification of mountain streams, and the introduction of non-native trout, are restricting habitat suitable for healthy populations of eastern brook trout (Salvelinus fontinalis) throughout their native Appalachian range. Brook trout are important as predators of insects in mountain streams and as a favorite of anglers. It is crucial that remaining populations in sustainable habitats be identified and preserved. Waterfalls are geologic knickpoints preventing base-level lowering that create unique, stable landscapes above them, which may alleviate the temperature-productivity/acidity “habitat squeeze” for populations of brook trout and could …
The Physico-Chemical Environment And Aquatic Biodiversity Of Head Marala Wetland During 2000-2001, Zahid Bhatti, Muhammad Asif Gondal, Andleeb Batool
The Physico-Chemical Environment And Aquatic Biodiversity Of Head Marala Wetland During 2000-2001, Zahid Bhatti, Muhammad Asif Gondal, Andleeb Batool
Journal of Bioresource Management
An ecological study on Head Marala Wetland was undertaken. The study will help in providing sound basis for the future conservation activities and its management, on sounder footing. The Marala wetlands in Bajwat area included river Jammu Tawi, river Chanab and river Manawar Tawi were studied for a period of one year, i.e. from October, 2000 to September, 2001. In this study, 36 Phytoplanktons belonging to six families were observed. The other aquatic fauna observed included 14 species of fish, 2 turtles, one leech, one prawn, one shrimp and one bullfrog. The results showed that physico-chemical parameters had an impact …
Distribution And Habitat Use Of Benthic Fishes In The Lower Kanawha River, West Virginia, Nathaniel V. Owens
Distribution And Habitat Use Of Benthic Fishes In The Lower Kanawha River, West Virginia, Nathaniel V. Owens
Graduate Theses, Dissertations, and Problem Reports
The Kanawha River in West Virginia is a historically diverse system in terms of ichthyofauna although, like many other large rivers, it has been subjected to a suite of anthropomorphic perturbations. These include this system being modified to allow the passage of commercial vessels for industry thus altering flow regimes, increased sedimentation, water depth, and channelization, and decreased interactions with its floodplain. Additionally, the fishes of this system have suffered from deleterious historical water quality issues caused by intensive timber operations, mining, and industrial waste. Post Clean Air Act, Clean Water Act, and Surface Mining Control and Reclamation Act water …
Novel Information On The Morphology, Phylogeny And Distribution Of Camallanid Mematodes From Marine And Freshwater Hosts In South Africa, Including The Description Of Camallanus Sodwanaensis N. Sp., Roman Svitin, Marliese Truter, Olena Kudlai, Nico J. Smit, Louis Du Preez
Novel Information On The Morphology, Phylogeny And Distribution Of Camallanid Mematodes From Marine And Freshwater Hosts In South Africa, Including The Description Of Camallanus Sodwanaensis N. Sp., Roman Svitin, Marliese Truter, Olena Kudlai, Nico J. Smit, Louis Du Preez
Harold W. Manter Laboratory: Library Materials
Four species of previously known nematodes from the family Camallanidae were found from different hosts in South Africa: Batrachocamallanus xenopodis from the frog Xenopus muelleri, Paracamallanus cyathopharynx, and Procamallanus pseudolaeviconchus from the catfish Clarias gariepinus and Spirocamallanus daleneae from the catfish Synodontis zambezensis. In the material collected from various marine fishes, several specimens of nematodes from the genus Camallanus clearly differed from all previously known species. Based on morphological differences these specimens are assigned to a new species, C. sodwanaensis. Molecular data of 18S and 28S rDNA and COI sequences are provided for the collected species …
