Phytoplankton temporal strategies increase entropy production in a marine food web model [PDF]
Entropy 2020, 22(11), 1249, 25 pp, 2020 We develop a trait-based model founded on the hypothesis that biological systems evolve and organize to maximize entropy production by dissipating chemical and electromagnetic potentials over longer time scales than abiotic processes by implementing temporal strategies.

Dynamics of a stochastic phytoplankton-toxin phytoplankton–zooplankton model [PDF]
Advances in Difference Equations, 2019 Abstract Environmental fluctuations and toxin-producing phytoplankton are crucial factors affecting marine ecosystems. In this paper, we propose a stochastic phytoplankton-toxin phytoplankton–zooplankton model to study the effect of environmental fluctuations on extinction and persistence of the population.

Hybrid quantum-classical convolutional neural network for phytoplankton classification [PDF]
arXiv, 2023 The taxonomic composition and abundance of phytoplankton, having direct impact on marine ecosystem dynamic and global environment change, are listed as essential ocean variables. Phytoplankton classification is very crucial for Phytoplankton analysis, but it is very difficult because of the huge amount and tiny volume of Phytoplankton. Machine learning

Comparative study on supervised learning methods for identifying phytoplankton species [PDF]
2016 IEEE Sixth International Conference on Communications and
Electronics (ICCE), Jul 2016, Ha Long, Vietnam. pp.283 - 288, 2016, 2017 Phytoplankton plays an important role in marine ecosystem. It is defined as a biological factor to assess marine quality. The identification of phytoplankton species has a high potential for monitoring environmental, climate changes and for evaluating water quality.

Journal 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 ...

The Chemistry of Phytoplankton
Chemical Reviews[Image: see text] Phytoplankton have a high potential for CO(2) capture and conversion. Besides being a vital food source at the base of oceanic and freshwater food webs, microalgae provide a critical platform for producing chemicals and consumer products. Enhanced nutrient levels, elevated CO(2), and rising temperatures increase the frequency of algal

Spatial dynamics of a nutrient–phytoplankton system with toxic effect on phytoplankton [PDF]
Mathematical Biosciences, 2015 The production of toxins by some species of phytoplankton is known to have several economic, ecological, and human health impacts. However, the role of toxins on the spatial distribution of phytoplankton is not well understood. In the present study, the spatial dynamics of a nutrient-phytoplankton system with toxic effect on phytoplankton is ...
