Effects of Small Dams on Freshwater Bivalve Assemblages in North Carolina Piedmont and Coastal Plain Streams 2012 3118 Small dams represent one of the most widespread human alterations to North American streams, yet effects on bivalve assemblages are understudied. Dams are quickly being removed and prioritizing dams for removal presents a challenge for resource mana...
Beaver and Mill Dams Alter Freshwater Mussel Habitat, Growth, and Survival in North Carolina Piedmont Streams 2012 3435 Freshwater mussels are imperiled indicator species, perform key ecosystem services, and serve as basal resources in stream foodwebs. Increasing beaver populations and mill dam removals may have consequences on freshwater mussel growth and survival. T...
Changes in the Freshwater Mussel Assemblage in the East Fork Tombigbee River, Mississippi: 1988-2011 2013 2047 The Tennessee-Tombigbee Waterway facilitates barge navigation between the Tennessee River drainage and Mobile River Basin via locks, dams, canals, and diverted streams. These alterations have destroyed habitat and isolated freshwater mussel populatio...
The Effects of Low-Head Dams and Land Use Change on North Carolina Atlantic Slope Fish Community Structure 2013 2473 Dams impound streams, alter sediment regimes and other physicochemical characteristics, and fragment populations. Low-head dams are ubiquitous in eastern North America and impact communities across broad geographic scales. We sampled fish at 25 dam...
Effects of Ski Slopes on Appalachian Headwater Streams 2013 1732 Mountain ecosystems are increasingly stressed by human activities. Ski resorts and other winter recreation areas (WRAs) are popular in montane regions including the Southern Appalachian Mountains. Large-scale land clearing and water extraction asso...
Phylogeny of the critically endangered North American spinymussels (Unionidae: Elliptio and Pleurobema) 2014 2352 Lateral spines are uncommon among freshwater bivalves. The North American freshwater mussel fauna includes three taxa that exhibit spines: Elliptio spinosa, Elliptio steinstansana, and Pleurobema collina. All three taxa are endemic to the Southeaster...
Effects Of Climate, Land Use And In-Stream Habitat On Appalachian Elktoe (Alasmidonta Raveneliana) In The Nolichucky River Drainage, North Carolina 2016 1392 The Appalachian elktoe (Alasmidonta raveneliana) is endemic to the Blue Ridge Physiographical Province in western North Carolina and eastern Tennessee. Populations are small and geographically isolated in the headwaters of 10 streams in western North...
Status And Population Genetics Of The Alabama Spike (Elliptio Arca) In The Mobile River Basin 2017 879 Declines in freshwater mussels (Bivalvia: Unionioda) are widely reported but rarely rigorously tested, the population genetics of most species are virtually unknown. In the Mobile River Basin (MRB), many range-restricted taxa have been heavily impact...
Mill Dam Effects on Freshwater Mussel Growth in an Alabama Stream 2010 4251 Small dams are common in the southeastern U.S., yet few studies have quantified their effects on the region’s aquatic biota such as imperiled freshwater mussels. I investigated why freshwater mussels are more abundant and larger immediately downstrea...
Molecular and Morphological Evidence for Multiple Cryptic Crayfish Invasions in the Southern Appalachian Mountains 2014 1392 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 1707 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 687 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 ...
Spatiotemporal Dynamics Of Interstitial Sediments And Mussel Populations In The South Toe River 2018 405 Sedimentation impacts freshwater biodiversity but quantifying interstitial sediment composition can be challenging. The South Toe River (STR) is a headwater of the Tennessee River in western North Carolina that supports endangered Appalachian elktoe ...
Comparing The Effectiveness Of Diurnal Rock-Lifting And Nocturnal Dive-Lighting Surveys For Eastern Hellbenders 2020 441 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...
Response Of Brook Trout (Salvelinus Fontinalis) Populations To Habitat Conditions And Competition In Southern Appalachian Streams 2021 266 Brook Trout (Salvelinus fontinalis) were largely extirpated from the southeastern Appalachian Mountains in the late 19th and early 20th centuries. Following this collapse, non-native S. fontinalis from northern hatcheries were stocked along with Rain...
Distribution Of Microplastics In Freshwater Mussels Across A Watershed Scale 2023 159 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...
The Effects Of Beaver Impoundments On Montane Stream Fish Communites 2020 604 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 457 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...
Host Fishes Of Two Imperilled Freshwater Mussels: The Appalachian Elktoe (Alasmidonta Raveneliana) And The Longsolid (Fusconaia Subrotunda) 2022 222 Freshwater mussels have complicated life histories and their larvae are briefly parasitic on fishes. This presumably enhances dispersal and apparently aids the development of juveniles. Despite many advances in mussel propagation, many mussel-host fi...
Phylogeography And Population Genetics Of The Carolina Heelsplitter (Lasmigona Decorata) A Critically-Endangered Freshwater Mussel 2023 44 The Carolina heelsplitter (Lasmigona decorata) is a federally-endangered freshwater mussel that historically occurred in the Pee Dee, Santee and Savannah basins in Georgia, North Carolina, and South Carolina. Captive propagation and population augmen...
Changes To Water Chemistry And Implications For Sensitive Aquatic Biota In Southern Blue Ridge Streams 2023 179 Freshwater systems, which constitute a mere 2.5% of Earth's total water, are increasingly impacted by abiotic and biotic factors. Changes to land use and other anthropogenic stressors are widely understood to drive the alteration of freshwater ecosys...
Modeling The Variable Effects Of Low-Head Dams On Freshwater Mussel Assemblages 2016 843 The widespread damming of lotic ecosystems is commonly associated with dramatic ecological effects such as decreased temperature, hypoxia, altered flow regime, physical changes to the structure of the river, and fragmentation of important habitats of...
