Mill Dam Effects on Freshwater Mussel Growth in an Alabama Stream 2010 3638 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...
Effects of Small Dams on Freshwater Bivalve Assemblages in North Carolina Piedmont and Coastal Plain Streams 2012 2568 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 2600 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...
Effects of Ski Slopes on Appalachian Headwater Streams 2013 1465 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...
Changes in the Freshwater Mussel Assemblage in the East Fork Tombigbee River, Mississippi: 1988-2011 2013 1575 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 2091 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...
Molecular and Morphological Evidence for Multiple Cryptic Crayfish Invasions in the Southern Appalachian Mountains 2014 1109 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...
Phylogeny of the critically endangered North American spinymussels (Unionidae: Elliptio and Pleurobema) 2014 1764 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 693 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...
Modeling The Variable Effects Of Low-Head Dams On Freshwater Mussel Assemblages 2016 491 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...
The Behavioral Responses Of Two Appalachian Crayfish To Cool And Warm Spectrum LED Light At Night 2016 2550 Ecological light pollution is increasing worldwide, and the use of artificial lighting is expected to increase during the coming decades. It is not clear how the different spectral emissions produced by the two most common LED categories will affect ...
Molecular Phylogeny Of The Freshwater Mussel Family Dreissenidae 2017 908 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...
Status And Population Genetics Of The Alabama Spike (Elliptio Arca) In The Mobile River Basin 2017 457 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...
Spatiotemporal Dynamics Of Interstitial Sediments And Mussel Populations In The South Toe River 2018 115 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 ...
Influence Of Water Chemistry And Predator Communities On The Egg Mass Polymorphism Of Ambystoma maculatum 2019 74 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 ...
Estimating Appalachian Elktoe Distribution And Abundance Using Occupancy And Detection Models 2019 70 Understanding the factors influencing the abundance, density, occupancy and detectability of endangered species is a critical component of managing at-risk species. The Appalachian elktoe (Alasmidonta raveneliana) is an endangered freshwater mussel e...
