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

Photosynthetic pigments in phytoplankton living in high latitudes under conditions of the polar night [PDF]

Vestnik MGTU, 2016
Pigment composition and the vertical distribution of phytoplankton chlorophyll have been studied for the first time in the Barents Sea during the period when there is no photosynthetically active radiation.

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

Temperature orchestrates phytoplankton community and environment in mountain stream for enhancing resource use efficiency

Frontiers in Marine Science
Warming is a key factor influencing the function of the structure and function of phytoplankton communities. However, the impacts of temperature on phytoplankton resource use efficiency (RUE) in mountain rivers remain poorly understood.

Combatting cyanobacteria with hydrogen peroxide: a laboratory study on the consequences for phytoplankton community and diversity

Frontiers in Microbiology, 2015
Experiments with different phytoplankton densities in lake samples showed that a high biomass increases the rate of HP degradation and decreases the effectiveness of hydrogen peroxide (HP) in the selective suppression of dominant cyanobacteria ...

Future phytoplankton diversity in a changing climate

Nature Communications, 2021
Phytoplankton form the base of the marine ecosystem but current ocean models used for climate change projections are too simple to assess potential changes in plankton community structure.

Space-time variability of phytoplankton structure and diversity in the north-western part of the Arabian Gulf (Kuwait)

BioRisk, 2009
Studies of the phytoplankton community were conducted in the north-western Arabian Gulf in 2005 and 2006. Seven stations throughout Kuwait’s waters were sampled.

Using optimized dimensionality reduction and machine learning to explain driving processes of phytoplankton community assembly in large mountain rivers

Ecological Indicators
Large mountain rivers create unique aquatic habitats and become one of biodiversity hot spots within ecosystems. Since phytoplankton constitutes a crucial component of primary productivity in aquatic ecosystems, understanding its community assembly ...
