Combined Effect of Light and Temperature on the Production of Saxitoxins in Cylindrospermopsis raciborskii Strains

open access: yesToxins, 2019
Cylindrospermopsis raciborskii is a potentially toxic freshwater cyanobacterium that can tolerate a wide range of light and temperature. Due to climatic changes, the interaction between light and temperature is studied in aquatic systems, but no study ...

A Bibliography of Periodical Literature Relating to the Law of Historic Preservation [PDF]

open access: yes, 1971
  We evaluated the trade-off between foraging activity and predation risk for larvae of an anuran species presented with different types of food resources. In the laboratory we examined the effects of benthic and phytoplankton resources and the two types

Evolutionary temperature compensation of carbon fixation in marine phytoplankton [PDF]

open access: yes, 2020
The efficiency of carbon sequestration by the biological pump could decline in the coming decades because respiration tends to increase more with temperature than photosynthesis.

PIBM 1.0: an individual-based model for simulating phytoplankton acclimation, diversity, and evolution in the ocean [PDF]

open access: yesGeoscientific Model Development
Phytoplankton is a diverse group of photosynthetic organisms and accounts for almost half of global primary production. However, most existing marine ecosystem models incorporate limited phytoplankton diversity, overlook phytoplankton evolution, and ...

Small phytoplankton contribution to the standing stocks and the total primary production in the Amundsen Sea [PDF]

open access: yesBiogeosciences, 2017
Small phytoplankton are anticipated to be more important in a recently warming and freshening ocean condition. However, little information on the contribution of small phytoplankton to overall phytoplankton production is currently available in the ...

Phytoplankton dynamics

open access: yesComptes Rendus. Biologies, 2004
We present a model of the phytoplankton dynamics. The distribution of the size of the phytoplankton aggregates is described by a non-linear transport equation that contains terms responsible for the growth of phytoplankton aggregates, their fragmentation and coagulation.

Temporal and spatial variations in phytoplankton productivity in surface waters of a warm-temperate, monomictic lake in New Zealand [PDF]

open access: yes, 2010
Surface phytoplankton productivity measurements were carried out in morphologically complex Lake Rotoiti with the objective of defining variations between sites and seasons, and the dominant environmental drivers of these variations.

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 ...

Changes in Phytoplankton Community Composition and Phytoplankton Cell Size in Response to Nitrogen Availability Depend on Temperature

open access: yesMicroorganisms, 2022
The climate-driven changes in temperature, in combination with high inputs of nutrients through anthropogenic activities, significantly affect phytoplankton communities in shallow lakes. This study aimed to assess the effect of nutrients on the community
