Ground-Truthing Maxent In East Texas Rivers, David F. Ford
Ground-Truthing Maxent In East Texas Rivers, David F. Ford
Biology Theses
Unionid mussels are a guild of freshwater, sedentary filter-feeders, which play a critical role in freshwater systems. Mussels are currently experiencing a global decline in both species richness and abundance, due to invasive species, human alteration of water systems, and climate change. In North America, which is considered to have the highest global diversity of bivalve species, native mussels are currently declining rapidly with at least 37 species considered to already be extinct. If extant mussel species are to be preserved, then it is vital that conservation efforts be prioritized towards areas in which they are likely to be found. …

Influence Of Substrate And Hydraulic Variables On Habitat Preferences Of A Sculptured And An Unsculptured Freshwater Mussel, Daniel Goodding
Influence Of Substrate And Hydraulic Variables On Habitat Preferences Of A Sculptured And An Unsculptured Freshwater Mussel, Daniel Goodding
Biology Theses
Freshwater mussels of the family Unionidae in North America have been in decline for at least the past 150 years. Major causes behind the decline are thought to be related to alteration or loss of habitat. Recent efforts by researchers have focused on understanding habitat associations of mussels so that more effective conservation efforts can be applied. Recent studies have identified variables that limit mussel community distributions. These variables are a combination of substrate and hydraulic variables that are associated with substrate stability. Furthermore, recent studies have suggested mussel studies are most informative at larger spatial scales and at high …
Freshwater Mussel Communities Of The Florida Parishes, Louisiana: The Importance Of Spatial Scale, Anne Raynie Bambarger
Freshwater Mussel Communities Of The Florida Parishes, Louisiana: The Importance Of Spatial Scale, Anne Raynie Bambarger
LSU Master's Theses
The Southeastern United States has the most diverse and imperiled freshwater mussel (Unionidae) fauna in the world. The community structure and decline of these organisms is the result of complex interactions between biotic and abiotic factors, but the limited spatial scale of most community studies has failed to elucidate the underlying mechanisms shaping community structure. Basing community assessments solely on microhabitat variables alone has lead to stark contradictions in management recommendations and opposing definitions of habitat requirements for these organisms. However, with the introduction of GIS technology into aquatic management, it is now feasible to include variables from larger spatial …
