Phytoplankton Communities of Lentic Periphyton
Periphyton was cultured and its phytoplankton communities were identified based on morphological features. This included 24 genera belonging to the 6 classes. Highest number of genera was found in Bacillariophyceae followed by Cyanophyceae and Chlorophyceae. Whereas a single genus was documented from class Euglenophyceae, Ulvophyceae and Xanthophyceae. Hence, the study is quite handy for the id...
متن کاملPhotosynthesis-light relations of stream periphyton communities
The photosynthesis-irradiance (P-Z) relationship was examined in 10 intact periphyton communities from sites in eight streams that differed in ambient light, nutrient concentrations, and grazing pressure. Algal biomass ranged from 2.3 to 86 pg Chl a cm -* and taxonomic composition differed. Photoassimilation of 14C was measured in the laboratory at six light levels for each community. Photosynt...
متن کاملMetagenomic sequencing of marine periphyton: taxonomic and functional insights into biofilm communities
Periphyton communities are complex phototrophic, multispecies biofilms that develop on surfaces in aquatic environments. These communities harbor a large diversity of organisms comprising viruses, bacteria, algae, fungi, protozoans, and metazoans. However, thus far the total biodiversity of periphyton has not been described. In this study, we use metagenomics to characterize periphyton communit...
متن کاملPresence and sources of fecal coliform bacteria in epilithic periphyton communities of Lake Superior.
Epilithic periphyton communities were sampled at three sites on the Minnesota shoreline of Lake Superior from June 2004 to August 2005 to determine if fecal coliforms and Escherichia coli were present throughout the ice-free season. Fecal coliform densities increased up to 4 orders of magnitude in early summer, reached peaks of up to 1.4x10(5) CFU cm-2 by late July, and decreased during autumn....
متن کاملLong-term effects of the antibacterial agent triclosan on marine periphyton communities.
Triclosan is a widely used antibacterial agent that has become a ubiquitous contaminant in freshwater, estuary, and marine environments. Concerns about potential adverse effects of triclosan have been described in several recent risk assessments. Its effects on freshwater microbial communities have been well studied, but studies addressing effects on marine microbial communities are scarce. In ...
