The effect of ultraviolet radiation into the Lake Chapala trophic processes was investigated in this study. Responses of bacterial populations to changes in UV radiation exposed water were significantly greater (bacterial ...

Waco reservoir was sampled for one year at five sample sites and six months at two sample sites in an attempt to detect competition between D. lumholtzi and native zooplankton. No competition could be detected. Also ...

The effect of materials adsorbed onto flood-borne sediments on Brachionus calyciflorus was investigated in this study. Sediment samples were collected from the North Bosque River and South Bosque River which drain into ...

The effect of clays on cadmium toxicity to bacterial production and specific production was investigated in Lake Brazos, McLennan County, Texas. Bacterial production calculated from ^H-thymidine incorporation rates in ...

Aquatic macrophytes leak photosynthetically-fixed carbon as dissolved organic molecules. This leakage of organic carbon appears to be an energetically inefficient process. However macrophyte extracellular organic ...

Phytoplankton production is determined by light and inorganic nutrients which govern the biomass of primary producers. These variables are a function of watershed rainfall periodicity and water quality from the run-off ...

This study reports on bacterial cell size and abundance change during oxygen depletion of Belton and Stillhouse Hollow reservoir. Bacterial cell size and abundance are compared with amount of heterotrophic nanoflagella ...
