Variation in plastic responses of a globally distributed picoplankton species to ocean acidification
Phytoplankton are the basis of marine food webs, and affect biogeochemical cycles. As CO

Evolutionary temperature compensation of carbon fixation in marine phytoplankton
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. …

Adaptation of phytoplankton to a decade of experimental warming linked to increased photosynthesis
Phytoplankton photosynthesis is a critical flux in the carbon cycle, accounting for approximately
40% of the carbon dioxide fixed globally on an annual basis and fuelling the productivity …

[HTML][HTML] Environmental fluctuations accelerate molecular evolution of thermal tolerance in a marine diatom
Diatoms contribute roughly 20% of global primary production, but the factors determining
their ability to adapt to global warming are unknown. Here we quantify the capacity for …

Plasticity predicts evolution in a marine alga
Under global change, populations have four possible responses: ‘migrate, acclimate, adapt

Environmental stability affects phenotypic evolution in a globally distributed marine picoplankton
Marine phytoplankton can evolve rapidly when confronted with aspects of climate change
because of their large population sizes and fast generation times. Despite this, the importance …

Phytoplankton adaptation in ecosystem models
A Beckmann, CE Schaum, I Hense - Journal of theoretical biology, 2019 - Elsevier
We compare two different approaches to model adaptation of phytoplankton through trait
value changes. Both consider mutation and selection (MuSe) but differ with respect to the …

Metabolic traits predict the effects of warming on phytoplankton competition
Understanding how changes in temperature affect interspecific competition is critical for
predicting changes in ecological communities with global warming. Here, we develop a …

[HTML][HTML] The temperature dependence of phytoplankton stoichiometry: investigating the roles of species sorting and local adaptation
The elemental composition of phytoplankton (C:N:P stoichiometry) is a critical factor regulating
nutrient cycling, primary production and energy transfer through planktonic food webs. …
