Changes in the phytoplankton [PDF]

open access: yes, 1939
An article discussing changes observed in phytoplankton of the Lake District. An overview is given of previous phytoplankton studies undertaken in the area, detailing some changes found in various waterbodies. Water quality changes in Lake Windermere are

Grazing resistance in phytoplankton [PDF]

open access: yesHydrobiologia, 2020
AbstractPhytoplankton is confronted with a variable assemblage of zooplankton grazers that create a strong selection pressure for traits that reduce mortality. Phytoplankton is, however, also challenged to remain suspended and to acquire sufficient resources for growth.

Autonomous observations enhance our ability to observe the biological carbon pump across diverse carbon export regimes

open access: yesLimnology and Oceanography, EarlyView.
Abstract The expansion of autonomous observation platforms offers vast opportunities for analyzing ocean ecosystems and their role in carbon export. As part of the EXport Processes in the Ocean from RemoTe Sensing campaign, we autonomously measured the productivity regimes in two contrasting end‐member ecosystem states.

Picophytoplankton act as the primary consumers of excess phosphorus after the spring bloom in the eutrophic Baltic Sea

open access: yesLimnology and Oceanography, EarlyView.
Abstract Eutrophication in the Baltic Sea has caused an imbalance in the inorganic nitrogen (N) to phosphorus (P) ratio, leaving excess phosphate (PO4) after the phytoplankton spring bloom that terminates after N depletion. Using monitoring data, we demonstrated that the PO4 concentration has continued to increase in the outermost Gulf of Finland ...

Role of hydraulic residence time in shaping phytoplankton community assembly in the upper yellow river cascade reservoirs

open access: yesFrontiers in Environmental Science
Introduction: Cascade hydropower development significantly alters the structure and function of river ecosystems. Phytoplankton, as primary producers, are highly sensitive to environmental changes, and their diversity and community structure reflect the ...

Identification of environmental factors affecting the abundance and distribution of phytoplanktons in Shamil Dam Lake [PDF]

open access: yesبوم‌شناسی آبزیان, 2019
Microscopic suspended algae, or phytoplankton, are the prime source of organic matter supporting food webs in freshwater ecosystems. Studying the distribution of their population and understanding the interactions between environmental factors and the ...

Plankton communities today and tomorrow—potential impacts of multiple global change drivers and marine heatwaves

open access: yesLimnology and Oceanography, EarlyView.
Abstract In the context of global change, marine organisms are subjected not only to gradual changes in abiotic parameters, but also to an increasing number of extreme events, such as heatwaves. However, we still know little about the influence of heatwaves on the structure of marine communities, and experimental studies are needed to test the impact ...

Net phytoplankton and zooplankton in the New York Bight, January 1976 to February 1978, with comments on the effects of wind, Gulf Stream eddies, and slope water intrusions [PDF]

open access: yes, 1984
Results are given of monthly net phytoplankton and zooplankton sampling from a 10 m depth in shelf, slope, and Gulf Stream eddy water along a transect running southeastward from Ambrose Light, New York, in 1976, 1977, and early 1978.

Toxin-allelopathy among phytoplankton species prevents competitive exclusion [PDF]

open access: yesJournal of Biological Systems, 2006, 2006
Toxic or allelopathic compounds liberated by toxin-producing phytoplankton (TPP) acts as a strong mediator in plankton dynamics. On an analysis of a set of phytoplankton biomass-data that have been collected by our group in the North-West part of the Bay of Bengal, and by analysis of a three-component mathematical model under a constant as well as a ...
