Patterns Of Dispersion, Movement And Feeding Of The Sea Urchin Lytechinus Variegatus, And The Potential Implications For Grazing Impact On Live Seagrass, Adrianna Parson, Joseph M. Dirnberger, Troy Mutchler
Gulf and Caribbean Research
The sea urchin Lytechinus variegatus is a known grazer of both living and dead tissue of turtlegrass, Thalassia testudinum, occasionally denuding large areas of seagrass. Field studies have attempted to assess effects of herbivory on seagrass by enclosing urchins at various densities. However, it is unclear how unrestricted urchins affect seagrass at lower densities more typically observed in the field. This study describes movement, feeding, and distribution of L. variegatus within beds of T. testudinum in St. Joseph Bay, Florida (USA) to quantify this urchin’s impact as a seagrass grazer. Urchins were absent from portions of seagrass beds closest to …
Observations On The Life History Of The Bayou Killifish, Fundulus Pulvereus (Everman 1899) In Mississippi Tidal Marshes, Leah Corrine Gaines
Observations On The Life History Of The Bayou Killifish, Fundulus Pulvereus (Everman 1899) In Mississippi Tidal Marshes, Leah Corrine Gaines
Master's Theses
This study provides insight into the life history of the relatively unknown intertidal marsh fish Fundulus pulvereus (Everman), the bayou killifish. Monthly sampling for F. pulvereus took place in three different Mississippi tidal marshes over a period of 17 months (n=445). Observations on the diet, parasite fauna, and fecundity of the bayou killifish were documented on all specimens collected. Percent Occurrence and Percent Number coupled along with multivariate analyses indicated seasonal, site, and ontogenetic shifts in the diet of F. pulvereus. Dominant prey items consumed by F. pulvereus were copepods, mites, chironomids, and terrestrial and aquatic insects. The bayou …
