The underlying causes and effects of phytoplankton seasonal turnover on resource use efficiency in freshwater lakes

Ecology and Evolution, 2021
The extent of intra‐annual turnover in phytoplankton communities is directly associated with the overall diversity. However, our understanding of the underlying causes and effects of intra‐annual turnover remains limited.

Stronger effect of temperature on body growth in cool than in warm populations suggests lack of local adaptation

Ecography, EarlyView.
Body size is a key functional trait that has declined in many biological communities, partly due to changes in individual growth rates in response to climate warming. However, our understanding of growth responses in natural populations is limited by relatively short time series without large temperature contrasts and unknown levels of adaptation to ...

Phytoplankton community of fouling on artificial structures in Makchachkala seaport conditions

Юг России: экология, развитие, 2015
The contents structure and dynamics of phytoplankton community formation of fouling on artificial structures in the Dagestan coastal area of the Caspian sea are researched. The most intensive process of phytoplankton community formation has been noted in

Effects of Flood on Phytoplankton Diversity and Community Structure in Floodplain Lakes Connected to the Yangtze River

Diversity, 2022
Flood events can significantly affect the physical and biological processes of aquatic ecosystems in a short time, leading to rapid changes in phytoplankton community structure. The Huayanghe Lakes experienced extreme flooding in the summer of 2020, with

Effects of phytoplankton species distribution on particulate organic carbon dynamics along a coastal gradient

Ecography, EarlyView.
Phytoplankton communities affect carbon dynamics worldwide, strongly influencing the quality and quantity of organic carbon in coastal ecosystems. Yet, we still know little about the impacts of changing phytoplankton community composition on the potential carbon pathways in estuaries and coasts.

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

Frontiers 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 ...

Phytoplankton Community Structure in Dardanelle Reservoir, Arkansas, 1975-1982 [PDF]

, 1983
Phytoplankton data were collected with standard equipment and procedures over an eight-year period (1975-1982) in Dardanelle Reservoir, Arkansas. Community abundance and diversity at the genus level are described.

Nitrogen and phosphorus limitation of oceanic microbial growth during spring in the Gulf of Aqaba [PDF]

, 2009
Bioassay experiments were performed to identify how growth of key groups within the microbial community was simultaneously limited by nutrient (nitrogen and phosphorus) availability during spring in the Gulf of Aqaba's oceanic waters.

The relationship between cellular protein content and selenium accumulation in freshwater microalgae

Integrated Environmental Assessment and Management, EarlyView.
Abstract Variability in the bioconcentration of selenium (Se) by primary producers at the base of the food web results in uncertainty in predictions of bioaccumulation and ecological risk to higher trophic level organisms. Water chemistry, speciation of Se, and periphyton community composition have all been suggested as factors that contribute to ...

An absorption‐based approach to improved estimates of phytoplankton biomass and net primary production

Limnology and Oceanography Letters, 2022
The abundance and productivity of phytoplankton constrain energy transfer through marine food webs and the export of organic carbon to the deep ocean. Bio‐optical measurements correlate well with phytoplankton carbon (Cphyto), but the effect of taxonomic
