Dissolved Nutrient Ratios And Concentrations Affect Fungal Reproduction And Community Structure Associated With Submerged Leaf Litter And Wood, Jennifer Fitzgerald
Dissolved Nutrient Ratios And Concentrations Affect Fungal Reproduction And Community Structure Associated With Submerged Leaf Litter And Wood, Jennifer Fitzgerald
Electronic Theses and Dissertations
Litter-associated fungi are important intermediaries in carbon and energy flow in streams. They can obtain nitrogen (N) and phosphorus (P) from both the substrate and the water column. I tested the effects of dissolved nutrients (dissolved inorganic nitrogen (DIN) 40-975 µg/L, soluble reactive phosphorus (SRP) 2-135 µg/L, N:P ratios 2:1, 16:1, 128:1) on fungi associated with leaf litter (maple and rhododendron) and wood in streamside channels at Coweeta Long Term Ecological Research site, North Carolina. This study addressed two main questions: (1) will fungal reproduction (sporulation rate of aquatic hyphomycetes) peak at a dissolved N:P ratio similar to nutrient stoichiometry …
Depredation Of Diamondback Terrapin (Malaclemys Terrapin) Nests In North Inlet, Sc: Nest Predator Community And The Cues Used By Raccoons To Locate Nests, Samuel Al Buzuleciu Ii
Depredation Of Diamondback Terrapin (Malaclemys Terrapin) Nests In North Inlet, Sc: Nest Predator Community And The Cues Used By Raccoons To Locate Nests, Samuel Al Buzuleciu Ii
Electronic Theses and Dissertations
Predation on diamondback terrapin eggs has been studied in several terrapin populations across their broad geographic range; however, nest predators have not been studied in South Carolina. Objectives of this project were two-fold: first, identify predators of diamondback terrapin eggs in North Inlet, SC; and second, determine the source of olfactory cue(s) used by raccoons to locate terrapin nests. Terrapin nest predators were identified using a combination of camera traps, visual surveys and trackboards. Raccoons were dominant nest predators and depredated 347 of 349 (combined natural and simulated) terrapin nests during the 2013 nesting season. We identified the source of …
Assessment Of Bryophyte Communities Along The Waccamaw River, Sc, Christine Elizabeth Raczka
Assessment Of Bryophyte Communities Along The Waccamaw River, Sc, Christine Elizabeth Raczka
Electronic Theses and Dissertations
The focus of this study was to determine the bryophyte communities present along the Waccamaw River, South Carolina and determine if there are any environmental constraints affecting bryophyte diversity. Another aspect of this study was to determine if bryophyte communities are bioindicators for dissolved inorganic nutrients in the Waccamaw River. A total of 1050 bryophyte specimens were collected over the course of the study. Twelve genera were identified and consisted of thirteen moss species and one liverwort species. The bryophyte species were collected at seven sites along the Waccamw River in a nested sampling design which assessed the bryophytes growing …
