Effects of Polychlorinated Biphenyl on Marine Phytoplankton Communities

Nature, 1972
WE report here the first in situ bioassay of short term effects of polychlorinated biphenyl compounds (PCBs) on natural marine phytoplankton communities. (Synthesis and utilization of these industrial organochlorines have been discussed before1–5.) PCB residues have been identified in water, biota and sediment samples throughout the marine environment5–

LIMITING RESOURCES AND THE REGULATION OF DIVERSITY IN PHYTOPLANKTON COMMUNITIES

Ecology, 2001
Species diversity is a key concept in ecology, yet the mechanisms regulating diversity in most systems are not completely understood. To address this issue, we analyzed the relationship between phytoplankton diversity and limiting resources (N, P, Si, and light) over two summers in three lakes in the Yellowstone (Wyoming, USA) region.

An approach for mapping phytoplankton communities in freshwater lakes based on phytoplankton absorption features

Water Research
Phytoplankton communities play a crucial role in the lake ecosystem due to their varying characteristics, functions, and impacts of different phytoplankton groups. Understanding the composition of phytoplankton groups in freshwater lakes is essential for comprehending geochemical processes and managing water quality.

An in situ toxicity assay with the local phytoplankton community

Environmental Toxicology and Chemistry, 2011
AbstractThe present study describes an approach for toxicity estimates based on the in situ exposure of the local phytoplankton community immobilized in calcium-alginate beads. The assay was deployed in an acid mine drainage-impacted system, at a reference site and an impacted site.

Seasonal dynamics of phytoplankton community in a tropical wetland

Environmental Monitoring and Assessment, 2014
Phytoplankton species composition and seasonal changes were investigated in the Bhoj wetland Bhopal. Taxonomic composition, diversity, and abundance of phytoplankton were studied at nine stations from March 2008 to February 2010, in relation to various physico-chemical factors. Total phytoplankton species composition in the Bhoj wetland was represented

Phytoplankton Communities in Temperate Rivers

2012
The structure of phytoplankton communities was examined seasonally across five rivers with a focus on small cells and their relative importance. Picophytoplankton (0.2-2 μm), previously considered insignificant in rivers, reached densities as high as those observed in lakes and oceans (~ 10e4-10e5 cells/mL). Their relative importance was not a function

Population and community responses of phytoplankton to fluctuating light

Oecologia, 1998
Light is a major resource in aquatic ecosystems and has a complex pattern of spatio-temporal variability, yet the effects of dynamic light regimes on communities of phytoplankton are largely unexplored. I examined whether and how fluctuating light supply affects the structure and dynamics of phytoplankton communities.
