Effects Of Marsh Fragmentation And Patch Area On Fish And Nekton Assemblages In Mississippi, Jennifer R. Main
Effects Of Marsh Fragmentation And Patch Area On Fish And Nekton Assemblages In Mississippi, Jennifer R. Main
Honors Theses
Fragmentation divides continuous habitat into smaller patches. Fragmentation can also produce smaller populations of species, because fragmentation can split a population into smaller groups. Both terrestrial and aquatic ecosystems suffer from fragmentation. There are a variety of fishes that live along marsh, each depending upon the marsh for protection, food, and sometimes even competition. Species richness of fishes can be altered due to marsh fragmentation. I predict islands with a larger patch index should have a higher species richness of fishes. For this study, fish assemblages at 20 islands of marsh were sampled in the months of June and July …
Microhabitat Selection By The Tortoiseshell Limpet, Tectura Testudinalis (Müller), In Tide Pools On The Mid-Maine Coast, Emily R. Lyczkowski
Microhabitat Selection By The Tortoiseshell Limpet, Tectura Testudinalis (Müller), In Tide Pools On The Mid-Maine Coast, Emily R. Lyczkowski
Honors Theses
Microhabitat selection of the limpet Tectura testudinalis, an important grazer along the rocky Maine coast is examined using both mensurative and manipulative experiments. T. testudinalis substrate selection is essential to its survival in the unpredictable and harsh regime of the intertidal zone. At three sites studied in the Gulf of Maine, T. testudinalis selectively inhabits tidal pools and vertically oriented substrates. Both of these microhabitats reduce the degree of environmental stress (desiccation, extreme temperature, and hypersaline conditions) and predation experienced by individuals. Differences among sites are common, indicating the importance of varying environmental factors in regulating and influencing habitat selection …
The Distribution Of The Ctenophore, Mnemiopsis Leidyi (A. Agassiz), In A Vertical Thermal Gradient, James J. Leder Iii
The Distribution Of The Ctenophore, Mnemiopsis Leidyi (A. Agassiz), In A Vertical Thermal Gradient, James J. Leder Iii
Honors Theses
The distribution of organisms in an estuary is affected by a plethora of environmental factors. The ctenophore, Mnemiopsis leidyi, is found to exists over a wide range of these factors, temperature and salinity in particular, allowing it to occupy the estuary year round and make use of low salinity areas unavailable to most marine organisms.
