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 ...

[Corrigendum to] Effects of small-scale turbulence on lower trophic levels under different nutrient conditions [vol 32, pg 197, 2010] [PDF]

open access: yes, 2009
Small-scale turbulence affects the pelagic food web and energy flow in marine systems and the impact is related to nutrient conditions and the assemblage of organisms present.

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

The long‐term persistence of phytoplankton resting stages in aquatic ‘seed banks’

open access: yesBiological Reviews of The Cambridge Philosophical Society, 2018
In the past decade, research on long‐term persistence of phytoplankton resting stages has intensified. Simultaneously, insight into life‐cycle variability in the diverse groups of phytoplankton has also increased.

Size Class Dependent Relationships between Temperature and Phytoplankton Photosynthesis-Irradiance Parameters in the Atlantic Ocean

open access: yesFrontiers in Marine Science, 2018
Over the past decade, a number of methods have been developed to estimate size-class primary production from either in situ phytoplankton pigment data or remotely-sensed data.

The ecology of phytoplankton in Shropshire and Cheshire meres [PDF]

open access: yes, 1976
This review summarizes the findings of 5 years' research (June 1970-June 1975) on the meres of the Shropshire-Cheshire Plain. A mere is a small, shallow lake; supplied principally by ground water, whose chemical composition is infkuenced by the glacial ...

Effects of the herbicide Roundup on freshwater microbial communities: a mesocosm study [PDF]

open access: yes, 2007
The impact of the widely used herbicide glyphosate has been mainly studied in terrestrial weed control, laboratory bioassays, and field studies focusing on invertebrates, amphibians, and fishes.

Exploring the link between micro-nutrients and phytoplankton in the Southern Ocean during the 2007 austral summer

open access: yesFrontiers in Microbiology, 2012
Bottle assays and large-scale fertilisation experiments have demonstrated that, in the Southern Ocean, iron often controls the biomass and the biodiversity of primary producers.

Phytoplankton periodicity: its motivation, mechanisms and manipulation [PDF]

open access: yes, 1982
This review summarizes some recent work to find a generalized explanation of phytoplankton periodicity in lakes. Much of the observational and experimental evidence is drawn from work centred on the large enclosures (Lund Tubes) installed in Blelham Tarn,

Integrating functional diversity, food web processes, and biogeochemical carbon fluxes into a conceptual approach for modeling the upper ocean in a high-CO2 world [PDF]

open access: yes, 2005
Marine food webs influence climate by channeling carbon below the permanent pycnocline, where it can be sequestered. Because most of the organic matter exported from the euphotic zone is remineralized within the "upper ocean" (i.e., the water column ...
