Chlorophyll shading reduces zooplankton diel migration depth in a high-resolution physical–biogeochemical model [PDF]

open access: yesOcean Science
Zooplankton diel vertical migration (DVM) is critical to ocean ecosystem dynamics and biogeochemical cycles, by supplying food and injecting carbon into the mesopelagic ocean (200–800 m).

A laboratory system for examining the influence of light on diel activity of stream invertebrates [PDF]

open access: yes, 2002
I describe a laboratory system for investigating the role of light as a proximate cue for diel changes in locomotor activity and vertical location on the substrate of stream macro-invertebrates.

Going ballistic in the plankton: anisotropic swimming behavior of marine protists [PDF]

open access: yes, 2014
Diel vertical migrations (DVMs) of many plankton species, including single-celled protists, are well documented in the field and form a core component of many large-scale numerical models of plankton transport and ecology.

A new species of Peniculus (Copepoda: Siphonostomatoida) parasitizing mesopelagic myctophid fish: first discovery of colonization of the genus in deep water

open access: yesParasite, 2018
Peniculus hokutoae n. sp. is described on the basis of an ovigerous adult female parasitizing the caudal fin of the myctophid fish Symbolophorus evermanni (Gilbert, 1905), collected from Suruga Bay, Japan.

Diel vertical migration behaviour of Calanus hyperboreus at temperate latitudes

open access: yes, 1995
Samples historically collected and analysed by the Continuous Plankton Recorder survey in the North Atlantic and adjacent seas were used to examine temporal patterns in the near-surface abundance of copepodite stages V and VI Calanus hyperboreus (n = a ...

Comparison of average larval fish vertical distributions among species exhibiting different transport pathways on the southeast United States continental shelf [PDF]

open access: yes, 2005
Water currents are vertically structured in many marine systems and as a result, vertical movements by fish larvae and zooplankton affect horizontal transport (Power, 1984). In estuaries, the vertical movements of larvae with tidal periods can result in

Pacific Hake, Merluccius productus, Autecology: A Timely Review [PDF]

open access: yes, 2007
Pacific hake, Merluccius productus, the most abundant groundfish in the California Current Large Marine Ecosystem (CCLME), is a species of both commercial significance, supporting a large international fishery, and ecological importance, connecting ...

Acoustic insights into the zooplankton dynamics of the eastern Weddell Sea [PDF]

open access: yes, 2016
The success of any efforts to determine the effects of climate change on marine ecosystems depends on understanding in the first instance the natural variations, which contemporarily occur on the interannual and shorter time scales.

The Importance of Mesozooplankton Diel Vertical Migration for Sustaining a Mesopelagic Food Web

open access: yesFrontiers in Marine Science, 2019
We used extensive ecological and biogeochemical measurements obtained from quasi-Lagrangian experiments during two California Current Ecosystem Long-Term Ecosystem Research cruises to analyze carbon fluxes between the epipelagic and mesopelagic zones ...

Diel vertical migration of Peridiniopsis niei, Liu et al., a new species of dinoflagellates in an eutrophic bay of Three-Gorge Reservoir, China [PDF]

open access: yes, 2010
In spring, a typical dinoflagellate (Peridiniopsis niei Liu et al.) constitutes most of the phytoplankton biomass in most of eutrophic bay of Three-Gorge Reservoir (TGR, China). There are few field observations on vertical migration of the members of the
