Phytoplankton assemblage characteristics in recurrently fluctuating environments [PDF]
Annual variations in biogeochemical and physical processes can lead to nutrient variability and seasonal patterns in phytoplankton productivity and assemblage structure.

Sustenance of phytoplankton in the subpolar North Atlantic during the winter through patchiness [PDF]
This study investigates the influence of two factors that change the mixed layer depth and can potentially contribute to the phytoplankton sustenance over winter: 1) variability of air-sea fluxes and 2) three-dimensional processes arising from strong ...

Effect of large- and small- bodied zooplankton on phytoplankton in a eutrophic oxbow [PDF]
Macrozooplankton and microzooplankton effects on the phytoplankton were measured in situ in a eutrophic lake. Indigenous phytoplankton were incubated for 5 days in 301 mesocosms with either the macro- and microzooplankton (complete), microzooplankton ...

Phytoplankton dynamics in a changing Arctic Ocean
Changes in the Arctic atmosphere, cryosphere and Ocean are drastically altering the dynamics of phytoplankton, the base of marine ecosystems. This Review addresses four major complementary questions of ongoing Arctic Ocean changes and associated impacts ...

Omnivory by planktivores stabilizes plankton dynamics, but may either promote or reduce algal biomass [PDF]
Classical models of phytoplankton–zooplankton interaction show that with nutrient enrichment such systems may abruptly shift from limit cycles to stable phytoplankton domination due to zooplankton predation by planktivorous fish.

Phytoplankton Growth and Nutrients
Aims: We describe the different nutrients that phytoplankton require, their variation among phytoplankton groups and their different nutritional modes and acquisition mechanisms. We furthermore describe the consequences of nutrient scarcity and excess on competition among phytoplankton and the effects of anthropogenic nutrient enrichment on ...

Cylindrospermopsis raciborskii is a potentially toxic freshwater cyanobacterium that can tolerate a wide range of light and temperature. Due to climatic changes, the interaction between light and temperature is studied in aquatic systems, but no study ...

Small phytoplankton contribution to the standing stocks and the total primary production in the Amundsen Sea [PDF]
Small phytoplankton are anticipated to be more important in a recently warming and freshening ocean condition. However, little information on the contribution of small phytoplankton to overall phytoplankton production is currently available in the ...
