TL;DR: The results suggest that P. piscicida is a common, and normally benign, inhabitant of estuarine waters of the eastern coast of the United States.
Abstract: PCR and fluorescent in situ hybridization probes were used to assay for the presence of the dinoflagellate Pfiesteria piscicida in 170 estuarine water samples collected from New York to nothem Florida. 20% of samples tested positive for the presence of P. piscicida, including sites where fish kills due to Pjiesteria have occurred and sites where there was no historical evidence of such events. The results extend the lmown range of P. piscicida northward to Long Island, New York. The results also suggest that P. piscicida is a common, and normally benign, inhabitant of estuarine waters of the eastern

TL;DR: This paper found no significant differences in relative abundance of Eastern Red-backed Salamanders (Plethodon cinereus), American Toads (Bufo americanus), or all amphibians combined (P = 0.25) among unburned shelterwood stands and those treated with winter, spring, or summer burns.
Abstract: As part of a larger study examining the role of prescribed fire in regenerating upland oaks (Quercus spp.), seasonal prescribed burns (winter, spring, summer, and unburned control) were applied to first-stage shelterwood-harvested stands on Horsepen Wildlife Management Area in the Virginia Piedmont in 1995. Because fire impacts are poorly documented for herpetofaunal communities, we surveyed these stands in 1996 capturing 133 individuals of ten species during over 12,720 pitfall trapnights. We found no significant differences in relative abundance of Eastern Red-backed Salamanders (Plethodon cinereus) (P = 0.26), American Toads (Bufo americanus (P = 0.93), or all amphibians combined (P = 0.25) among unburned shelterwood stands and those treated with winter, spring, or summer burns. Three species of reptiles (Northern Fence Lizard [Sceloporus undulatus], Ground Skink [Scincella lateralis], and Southeastern Five-lined Skink [Eumeces inexpectatus]) combined were captured more frequently in burned versus unburned stands (P = 0.02). Based on a stepwise multiple regression model, Eastern Red-backed Salamander captures were more strongly influenced by landscape variables (P = 0.0320), including distance to permanent water and mesic (i.e., eastern-northern) aspects, than by fire treatments (P = 0.26). Similar landscape models were not significant (P < 0.05) for toads or reptiles. Based on these results, prescribed fire may not be detrimental to herpetofaunal communities in oak dominated forests in the Virginia Piedmont.

Abstract: Sporadic algal bloom development within a IO year monitoring program in Virginia tidal tributaries of Chesapeake Bay is reviewed. These blooms were common events, characteristically producing a color signature to the surface water, typically short lived, occurring mainly from spring into autumn throughout different salinity regions of these rivers. and were produced primarily by dinoflagcilatcs. The abundance threshold levels that would identify bloom status from a non-bloom presence were species specific, varied with the taxon's cell size, and ranged from ca. 10 to \\() cells ml • Among the most consistent sporadic bloom producers were the dinoflagcllatcs Akashiwo sanguinea, Cochlodinium polvkrikoides, Heterocapsa rotundata, Hetcrocapsa triquetra, Karlodinium l'eneficum, Prorocentrum minimum, Scrippsiella trochoidea, the cyanobacterium lvficrocystis aeruginosa, and two categories containing several species of often unidentified Gymnodinium spp. and Gyrodinium spp. Additional bloom producers within these tributaries arc also discussed.
