Phytoplankton Tune Local pH to Actively Modulate Circadian Gravitactic Behavior
Advanced Physics ResearchDiel vertical migration (DVM) is the daily movement of motile phytoplankton between light‐rich surface waters and deeper nutrient‐rich layers, typically governed by internal clocks. However, many species show irregular patterns that deviate from expected

Mean Field Games for Diel Vertical Migration with Diffusion. [PDF]
Bull Math Biol, 2023 AbstractWe present a theoretical framework, based on differential mean field games, for expressing diel vertical migration in the ocean as a game with a continuum of players. In such a game, each agent partially controls its own state by adjusting its vertical velocity but the vertical position in a water column is also subject to random fluctuations ...

Diel vertical migration promotes zooplankton horizontal patchiness [PDF]
Journal of Oceanography, 2020 AbstractSpatial patchiness of plankton enhances fishery production and carbon export in the ocean. While diel vertical migration (DVM) has been identified as an important factor contributing to vertical patchiness, its effect on horizontal patchiness has never been investigated.

Assessing mesopelagic fish diversity and diel vertical migration with environmental DNA
Frontiers in Marine Science, 2023 Mesopelagic fishes are an important component of the world’s oceans in terms of their abundance, biomass, and ecosystem function. These fishes are important contributors to the biological carbon pump via their feeding and behaviors, whereby they ...

Arctic complexity: a case study on diel vertical migration of zooplankton. [PDF]
J Plankton Res, 2014 Diel vertical migration (DVM) of zooplankton is a global phenomenon, characteristic of both marine and limnic environments. At high latitudes, patterns of DVM have been documented, but rather little knowledge exists regarding which species perform this ecologically important behaviour.

Modeling diel vertical migration with membrane computing
Journal of Membrane Computing, 2020 Diel vertical migration (DVM) is an important ecological phenomenon in which zooplankton migrate vertically to deal with trade-offs associated with greater food availability in shallow waters and lower predator risk in deep waters due to lower light availability.

Circadian Clock Involvement in Zooplankton Diel Vertical Migration [PDF]
Current Biology, 2017 Biological clocks are a ubiquitous ancient and adaptive mechanism enabling organisms to anticipate environmental cycles and to regulate behavioral and physiological processes accordingly [1]. Although terrestrial circadian clocks are well understood, knowledge of clocks in marine organisms is still very limited [2-5].

New insight into Salpa thompsoni distribution via glider-borne acoustics
Frontiers in Marine Science, 2023 Salpa thompsoni is an ephemerally abundant pelagic tunicate in the waters of the Southern Ocean that makes significant contributions to carbon flux and nutrient recycling in the region. While S.

Diel vertical migration: modelling light-mediated mechanisms [PDF]
Journal of Plankton Research, 1996 Light is generally regarded as the most likely cue used by zooplanlcton to regulate their vertical movements through the water column. However, the way in which light is used by zooplanlc- ton as a cue is not well understood. In this paper we present a mathematical model of diel vertical migration which produces vertical distributions of zooplankton ...
