Effect of large- and small- bodied zooplankton on phytoplankton in a eutrophic oxbow [PDF]

open access: yes, 2005
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 ...

A plankton community: a zooplankton effect in phytoplankton dynamics [PDF]

open access: yesКомпьютерные исследования и моделирование, 2019
The paper uses methods of mathematical modeling to estimate a zooplankton influence on the dynamics of phytoplankton abundance. We propose a three-component model of the "phytoplankton-zooplankton" community with discrete time, considering a ...

Environmental and spatial factors play different roles in phytoplankton community assembly in different hydrological seasons in Lake Wuchang, China

open access: yesFrontiers in Ecology and Evolution, 2023
Lake phytoplankton communities are affected by environmental and spatial factors. We studied the relative importance of environmental and spatial factors on the phytoplankton community assembly in Lake Wuchang across three hydrological seasons, which ...

Different Observational Methods and the Detection of Seasonal and Atlantic Influence Upon Phytoplankton Communities in the Western Barents Sea

open access: yesFrontiers in Marine Science, 2022
Phytoplankton community composition, and its dependency on environmental variation, are key to understanding marine primary production, processes of trophic transfer and the role of marine phytoplankton in global biogeochemical cycles.

Grazing Induced Shifts in Phytoplankton Cell Size Explain the Community Response to Nutrient Supply

open access: yesMicroorganisms, 2021
Phytoplankton cell size is important for a multitude of functional traits such as growth rates, storage capabilities, and resistance to grazing.

The Community Concept and the Phytoplankton

open access: yesMarine Ecology Progress Series, 1981
The community concept of terrestrial ecology is examined with particular reference to its application to phytoplankton dlstrlbutlon. I t IS suggested that it is more appropriate to regard phytoplankton distribution as entirely probabilistlc, comparable to a local situation in a tropical rain forest.

Effect of land use and environmental variables on phytoplankton community structure in high-elevation river, upper Yangtze river, China

open access: yesFrontiers in Environmental Science, 2023
The Qinghai-Tibet Plateau is an ecologically fragile region. The changes in physicochemical parameters of water quality [PPOWQ] and land use types [LUT] in different regions will affect the phytoplankton community in rivers, thus threatening the ...

3. Phytoplankton community

open access: yesZoology and Ecology, 2014
This article discusses the recent ecological status of Lake Drūksiai, the former cooler of the INPP, based on phytoplankton assessment in 2011. The data of integrated long-term investigation of phytoplankton over a period of 31 years from the construction of the INPP till decommissioning are also provided. The operation of the INPP obviously influenced

Initial size structure of natural phytoplankton communities determines the response to Daphnia diel vertical migration

open access: yesJournal of Limnology, 2012
Diel vertical migration (DVM) is a common behavior of many pelagic herbivorous zooplankton species in response to predation pressure. It is characterized by a twice daily habitat shift of the zooplankton species: staying in the epilimnion only during ...

Distributions of particulate Heme b in the Atlantic and Southern Oceans - implications for electron transport in phytoplankton [PDF]

open access: yes, 2013
Concentrations of heme b, the iron-containing component of b-type hemoproteins, ranged from  500). High chl a:heme b ratios resulted from relative decreases in heme b, suggesting proteins such as cytochrome b6f, the core complex of photosystem II, and ...
