Downwind gas condensate volatiles affect phytoplankton communities
Marine Pollution Bulletin, 2023We investigated the effects of volatile organic carbons (VOCs) evaporated from gas condensate on the cyanobacteria Synechococcus sp. WH8103, the diatom Asterionellopsis glacialis, and the dinoflagellate Alexandrium minutum. We used custom algal incubation chambers enabling only the gas condensate-derived VOCs to interact with the cell cultures via an ...

Dynamics of Phytoplankton Communities Under Photoinhibition
Bulletin of Mathematical Biology, 2013We analyzed a model of phytoplankton competition for light in a well-mixed water column. The model, proposed by Gerla et al. (Oikos 120:519-527, 2011), assumed inhibition of photosynthesis at high irradiance (photoinhibition). We described the global behavior through mathematical analyses, providing a general solution to the multi-species competition ...

Microplastics can alter phytoplankton community composition
Science of The Total Environment, 2022Microplastic pollution is a growing concern globally due to the risks they may pose to ecological communities. Phytoplankton are key ecological community in aquatic ecosystems providing both energy to food webs and have critical roles in ecosystem functions such as carbon cycling.

Phytoplankton community dynamics
1993Introduction Limnologists have long appreciated the potential importance of grazing to phytoplankton community composition (Reynolds, 1984 a ). At certain times during seasonal succession, grazers have clear-cut effects on algal assemblages (Lampert et al ., 1986; Sommer et al ., 1986; Vanni & Temte, 1990).

Photoacclimation of natural phytoplankton communities
Marine Ecology Progress Series, 2016Phytoplankton regulate internal pigment concentrations in response to light and nutrient availability. Chlorophyll a to phytoplankton carbon ratios (chl:Cphyto) are commonly reported as a function of growth irradiance (Eg) for evaluating the photoacclimation response of phytoplankton.

Triclosan alterations of estuarine phytoplankton community structure
Marine Pollution Bulletin, 2017Antimicrobial additives in pharmaceutical and personal care products are a major environmental concern due to their potential ecological impacts on aquatic ecosystems. Triclosan (TCS) has been used as an antiseptic, disinfectant, and preservative in various media.

Nutrient breakpoints for estuarine phytoplankton communities
Limnology and Oceanography, 2020AbstractNutrient breakpoints are the concentration at which there is a fundamental change in phytoplankton responses to further increases in nutrient loading. The ecological implication is that nutrient breakpoints signal a community transition from a relatively stable state to an alternate or transition state with marked changes in structure and, by ...
