First Records Of The Seagrass Parasite Plasmodiophora Diplantherae From The Northcentral Gulf Of Mexico, Allison K. Walker, Jinx Campbell
Gulf and Caribbean Research
Plasmodiophora diplantherae is known to occur throughout the pantropical distribution of its host, the seagrass genus Halodule. However, records in the subtropical region are limited to Tampa Bay, FL where it was detected once during an examination of herbar-ium specimens of H. beaudettei collected in December 1951 (den Hartog 1965) and to Fort Pierce, FL where it was collected once infecting H. wrightii (Braselton and Short 1985). This communication represents the first report of this parasite from Mississippi and Louisiana in the northcentral Gulf of Mexico (GOM).
A Comparison Of Fish Populations In Shallow Coastal Lagoons With Contrasting Shoalgrass (Halodule Wrightii) Cover In The Northcentral Gulf Of Mexico, Just Cebrian, Glenn A. Miller, Jason P. Stutes, Adrienne L. Stutes, Mairi E. Miller, Kate L. Sheehan

Gulf and Caribbean Research
A number of studies have examined the effects of reduced seagrass cover on local fish populations (e.g., Heck et al. 1989, Ferrell and Bell 1991, Hughes et al. 2002 and more), but few of those studies have focused on shoalgrass (e.g., Tolan et al. 1997, Rydene and Matheson 2003). We present a preliminary comparison of fish populations in three shallow coastal lagoons in the northcentral GOM that have varying levels of shoalgrass cover. Namely, we compare (1) abundances of individual species and the entire fish population, (2) fish population diversity, and (3) length-frequency distributions of the most abundant species.
