Evaluating Habitat Use By Nekton In Widgeon Grass (Ruppia Maritima), Shoal Grass (Halodule Wrightii), And Unvegetated Bottom Habitats In The Grand Bay National Estuarine Research Reserve, Jessica Woodall
Master's Theses
Seagrass beds support high biodiversity and animal abundance, serve as feeding grounds for a variety of animals, offer shelter from predation, and act as a nursery habitat for juveniles. The species composition of seagrass beds can impact their use as habitat by animals. Two common species of seagrass in the Gulf of Mexico are Ruppia maritima (widgeon grass) and Halodule wrightii (shoal grass). The shallow coastal waters of the Grand Bay National Estuarine Research Reserve (NERR) support both species, but the use of each seagrass as habitat by nekton is poorly understood, which can limit management decision-making. Nekton communities were …
Effects Of Wave Action On The Structure Of Fish Assemblages Across An Exposure Gradient, Lauren Liddon
Effects Of Wave Action On The Structure Of Fish Assemblages Across An Exposure Gradient, Lauren Liddon
Master's Theses
Disturbance affects the function and diversity of ecosystems. Increased wave exposure to salt marsh can disturb sediments and cause a loss of habitat. The purpose of this study was to explore the effects of increased wave exposure on diversity, abundance, and functional ecology of estuarine fishes. If increased wave exposure is acting as a disturbance to these habitats, ecological theory (Intermediate Disturbance Hypothesis) predicts that diversity will peak at intermediate frequencies and intensities of disturbance. Fish were sampled from 10 sites monthly for 6 years. The sites were assigned to different exposure categories (Open, Intermediate, and Sheltered) using an exposure …
Growth And Food Habits Of Micropterus Salmoides In Westhampton Lake, Richmond, Virginia, Charles H. Rawls Jr.
Growth And Food Habits Of Micropterus Salmoides In Westhampton Lake, Richmond, Virginia, Charles H. Rawls Jr.
Master's Theses
Age, growth, and food habits of the population of Micropterus salmoides (largemouth bass) in Westhampton Lake were studied from September to November 1978. Two year classes (0 and I) were identified by determining numbers of annuli on the scales of the fish. Growth data indicated that the bass attain a size of 254 mm (10 in.) near the end of their second summer. The length-weight relationship was log W = -4.6829 + 2.9153 log TL. The Fulton condition factor for the population was 1.40. Food habits were described by numerical and frequency of occurrence methods. Young of the year sunfish …
