The crayfish genus Orconectes is widespread in North America and most diverse in the southeastern river drainages. Orconectes includes numerous drainage or regional endemics as well as several species considered to be aggressive invaders of freshwate... |
| Molecular Phylogeny Of The Freshwater Mussel Family Dreissenidae |
2017 |
1772 |
The bivalve family Dreissenidae contains some of the most economically and ecologically important fresh and brackish-water mollusk species. There has been much uncertainty surrounding phylogenetic resolution for members of Dreissenidae. The lineage i... |
| Influence Of Water Chemistry And Predator Communities On The Egg Mass Polymorphism Of Ambystoma maculatum |
2019 |
786 |
Spotted salamanders (Ambystoma maculatum) migrate each spring to temporary ponds to mate. The females lay their eggs in two morphs: clear and opaque. The presence or absence of hydrophobic protein crystals in the egg mass jelly influence whether the ... |
| Comparing The Effectiveness Of Diurnal Rock-Lifting And Nocturnal Dive-Lighting Surveys For Eastern Hellbenders |
2020 |
582 |
Studies designed to better understand perceived hellbender population declines typically use diurnal rock-lifting surveys to detect individuals. However, these methods are invasive as they may alter sheltering or breeding habitat or result in injurie... |
| The Effects Of Beaver Impoundments On Montane Stream Fish Communites |
2020 |
732 |
North American beavers (Castor canadensis) are ecological engineers, and their dams alter stream environments. Few studies have examined the effect of beaver dams on Southern Appalachian fishes. I sampled fish communities from 9 streams with active b... |
| Influence Of Interstitial Sediments On An Endangered Freshwater Mussel Population |
2020 |
551 |
Erosion and transport of sediment and associated pollutants to rivers and other aquatic systems is among the most commonly-reported yet poorly-understood water quality stressors. Freshwater mussels are benthic invertebrates that spend much of their l... |
| Distribution Of Microplastics In Freshwater Mussels Across A Watershed Scale |
2023 |
278 |
For this study, water, freshwater mussels, and sediment samples were collected from 5 sites along the Yadkin-Pee Dee River Basin. These samples were digested, filtered, and analyzed for microplastic particles. There were significant differences in wa... |
| Phylogeography And Population Genetics Of The Carolina Heelsplitter (Lasmigona Decorata) A Critically-Endangered Freshwater Mussel |
