Pelagic community production and carbon-nutrient stoichiometry under variable ocean acidification in an Arctic fjord [PDF]

open access: yes, 2013
Net community production (NCP) and carbon to nutrient uptake ratios were studied during a large-scale mesocosm experiment on ocean acidification in Kongsfjorden, western Svalbard, during June–July 2010. Nutrient depleted fjord water with natural plankton

PondNet – towards a global network of experiments on the effects of climate change on aquatic ecosystems

open access: yesEcography, EarlyView.
Global change is reshaping the distribution of biodiversity and the functioning of ecosystems. Predicting the long‐term consequences of such changes remains a challenge due to a need for a clear understanding of the mechanisms underpinning ecosystem‐level responses, as well as the role of geographical and environmental contingencies.

Phytoplankton dynamics of the river nene, England [PDF]

open access: yes, 2000
The distribution of suspended algae was investigated in a 69-km length of a small lowland river in the UK, the Nene (annual median discharge at km 91.7 =6 m(^3) s(^-1).

Phytoplankton community of Reis lake in the Brazilian Amazon [PDF]

open access: yesAnais da Academia Brasileira de Ciências, 2013
Reis Lake is located in the municipality of Caracaraí, state of Roraima (Brazil) and is subject to fluctuations in water level. The aim of this study was to analyze the structure of the phytoplankton community on the nictemeral and seasonal scales and determined the influence of limnological variables.

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

open access: yesIntegrated 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 ...

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

open access: yesVestnik 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.

Distributions of particulate Heme b in the Atlantic and Southern Oceans-Implications for electron transport in phytoplankton

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 ...

Phytoplankton community structure in the VAHINE MESOCOSM experiment [PDF]

open access: yesBiogeosciences, 2016
Abstract. The VAHINE mesocosm experiment was designed to trigger a diazotroph bloom and to follow the subsequent transfer of diazotroph derived nitrogen (DDN) in the rest of the foodweb. Three mesocosms (50 m3) located inside the Nouméa lagoon (New Caledonia, South West Pacific) were enriched with dissolved inorganic phosphate (DIP) in order to promote
