Comparison of free-living and particle-associated bacterial communities in the Chesapeake Bay by stable low-molecular-weight RNA analysis
Article Abstract:
A comparative study of the numbers of free-living and particle-associated bacterial communities in the Chesapeake Bay by low-molecular-weight (LMW) RNA analysis and acridine orange direct counts reveals the domination of free-living bacteria at all sampling sites, and sites with higher particle loads have more number of particle-associated bacteria. LMW RNAs of particle-associated and free-living communities of the same site have distinct migration distances, suggesting compositional differences in the two communities. 5S rRNAs of both communities are compared.

Natural microbial community compositions compared by a back-propagating neural network and cluster analysis of 55 rRNA
Article Abstract:
Stable low-molecular-weight (SLMW) RNA analysis was utilized to compare the community compositions of free-living and particle-associated bacteria collected from Chesapeake Bay. The novel approach for comparing the SLMW RNA bands of bacteria communities was based on data from three trained back-propagating artificial neural networks. Furthermore, cluster analysis of 5S ribosomal RNA indicated the seasonal and spatial variations of the natural microbial community of Chesapeake Bay estuary.

Contrasting patterns of phytoplankton community pigment composition in two salt marsh estuaries in southern United States
Article Abstract:
Results indicate that phytoplankton community pigment patterns in the salt marsh estuaries vary with season, exhibit similar diversities but differ in composition. The two estuaries display differences with respect to the timing, magnitude, and pigment composition of the annual phytoplankton bloom.
