Effect of Fragmentation and Habitat Type on Coastal Nekton in Mississippi
… and distribution data for non-harvested marsh nekton collected in oligohaline marshes (salinity 0.5-5ppt) of coastal Mississippi. To assess how nekton assemblages varied by habitat, fragmentation level and position in patch (core vs. edge), four sites along coastal Mississippi were sampled in …

Investigating Nekton Response to Changing Salinities in the Mississippi Sound: An Experimental and Statistical Approach
… effects of salinity and temperature on nekton under average conditions and during freshening events. Laboratory-based experiments were used to quantify survival, biomass change, and caloric content of grass shrimp (<em>Palaemon spp.</em>), an important prey species, under different …

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
… but the use of each seagrass as habitat by nekton is poorly understood, which can limit management decision-making. Nekton communities were sampled in May, July, September, and November 2022 in the Grand Bay NERR within <em>R. maritima</em> and <em>H. wrightii</em>-dominated seagrass beds …

Effects of shoreline development and freshwater discharge on nekton assemblage and trophic structure in a northern Gulf of Mexico estuary
<p>Coastal salt marshes support a diversity of nekton and facilitate critical ecosystem functions but are threatened by shoreline development and climate change. Therefore, coastal ecosystem managers have begun incentivizing the use of living shorelines (LS), erosion control structures …

Addressing the land loss-fish production paradox
… has had on historical abundance of estuarine nekton in Barataria Bay, LA is lacking. I first examined the differences between fishery independent and fishery dependent data as indices of relative abundance. Previous studies used landings data to evaluate the importance of marsh habitat (e.g. …

Fish and decapod community structure in estuarine habitats of the New Orleans Land Bridge, including a description of the life cycle of tarpon (Megalops atlanticus) in southeastern Louisiana
… marsh. My research details the distribution of nekton across five contiguous but geomorphically different regions, which I defined as “Areas”. This factor “Area” was significant in explaining community composition differences in 11 of the 24 months I evaluated. That is, during those 11 months …

The Aquatic Ecology of Two Seasonal Marshes in Eastern South Dakota
Zooplankton, benthos, nekton, aufwuchs, and the physical-chemical limnology of two seasonal marshes in eastern South Dakota were monitored from April-June 1975. Bothwell and Lund Marshes contained water from 15 April-July 1975. The dominant i. ons, Ca ++, Mg+ +, and sulfate, made the water hardness …

Experimental determination of pressures and velocities in plant xylem
… were compared with a numerical simulation using NEKTON, a computational fluid dynamics package. Experimental results and the numerical results agreed with each other. In the experiments involving the 20-pore perforation plate, the average loss coefficient was 86,300 over the range {dollar}\rm 0.2 …

Evaluating Marsh Restoration Success Using Structural and Trophic Metrics on Deer Island, MS
… sampling were used to compare invertebrate and nekton abundance, species richness, and diversity of two restored marshes (5+ yrs and 15+ yrs) with a natural reference marsh (100+ yrs old). Stable isotope analysis was also used to compare basal carbon sources and trophic support between sites. …

Occurrence and genetic diversity of lemon sharks (Negaprion brevirostris) at a nursery ground at the Chandeleur Islands, Louisiana.
… Louisiana. From May 2009 to August 2011, the Nekton Research Laboratory at the University of New Orleans regularly sampled habitats at the Chandeleur Islands to confirm the presence of immature individuals of this species. During these efforts, 147 immature lemon sharks (neonates, …

The ecology of two estuarine-dependent tonguefishes, the blackcheek tonguefish (Symphurus plagiusa) and the offshore tonguefish (S. civitatium), in coastal Louisiana
… and abundance of estuarine-dependent nekton. Given the importance of nursery function of inshore estuaries in coastal Louisiana, it is of interest to explore the response of estuarine-dependent organisms to environmental gradients. To this end I examined the ecology of two sympatric …

The recreation of estuarine ecosystem : a case study at Paull Holme Strays, Humber Estuary, UK.
… filters, flood buffers, nurseries for juvenile nekton and as wildlife habitat for birds and animals. Creation of costal wetland habitat with intact ecological functions remains a challenging task. Paull Holme Strays (PHS) is an example of a restored coastal wetland on the Humber Estuary, UK. …
