Fish And Macroinvertebrate Response To Restoration And Conservation Efforts, Madison C. Cogar
Fish And Macroinvertebrate Response To Restoration And Conservation Efforts, Madison C. Cogar
MSU Graduate Theses
Fish and macroinvertebrate response to restoration and conservation efforts varies in regards to the size and structure of the system (e.g. headwater streams in WV versus large rivers such as the Mississippi River). This project reviews fish and macroinvertebrate rebound in treated acid mine drainage (AMD) streams in WV as well as macroinvertebrate drift patterns in the Mississippi and Missouri Rivers. AMD is a product of a chemical reaction resulting in an acidic water outflow from mining sites, which may harm aquatic life. As a response, passive AMD treatment systems have been installed. I tested the effectiveness of remediation by …
Population Surveys And Health Assessments Of Captive And Free-Ranging Alligator Snapping Turtles, Samantha Louise Hannabass
Population Surveys And Health Assessments Of Captive And Free-Ranging Alligator Snapping Turtles, Samantha Louise Hannabass
MSU Graduate Theses
Alligator Snapping Turtles (Macrochelys temminckii) have experienced range-wide declines primarily due to overharvest for the meat market and habitat degradation in the form of damming and channelization of rivers. Head-start programs and reintroduction efforts have been initiated to release individuals throughout their historic range. Before releasing Alligator Snapping Turtles, sites need to be assessed to determine the suitability of habitat, if there is a robust turtle community already present, and the causes of the original extirpation have been eliminated. I assessed the turtle communities and documented anthropogenic impacts (e.g. boat traffic) at nine possible reintroduction sites in southeastern …
Dragonflies And Damselflies (Insecta: Odonata) As Indicators For Riparian Condition In Ozark Spring Streams, Cameron Riley Cheri
Dragonflies And Damselflies (Insecta: Odonata) As Indicators For Riparian Condition In Ozark Spring Streams, Cameron Riley Cheri
MSU Graduate Theses
The Odonata (dragonflies and damselflies) are often ineffectively sampled during standard stream bioassessments in North America. Subsequently, odonates are not frequently regarded as informative taxa for stream assessment, particularly when monitoring the ecological impacts of organic pollution. I hypothesized that stream-dwelling odonates should be more useful bioindicators for the assessment of riparian conditions surrounding streams because vegetation associated with streams is used for oviposition, roosting and to establish breeding territories. I selected twelve Ozark spring streams that satisfied a broad array of riparian conditions for study. I sampled each stream’s odonate and total benthic community along with both instream and …
Habitat Selection And Host Detection In The Salamander Mussel, Simpsonaias Ambigua, Eric A. Stegmann
Habitat Selection And Host Detection In The Salamander Mussel, Simpsonaias Ambigua, Eric A. Stegmann
MSU Graduate Theses
The native freshwater mussels, Order Unionida, have suffered many species extinctions and loss of abundance. Two important threats to native mussels are loss of habitat and loss of access to the vertebrate hosts of the parasitic mussel larvae. The Salamander mussel, Simpsonaias ambigua, is a habitat specialist, living under flat rocks. It is often found in direct association with its only known host, the common mudpuppy, Necturus maculosus. This association could result from movement and habitat selection by the mussels themselves. Alternatively, it might result from the deposition of juveniles by a resident host. Habitat selection and host …
