Krill diel vertical migration in Southern Patagonia

Journal of Plankton Research, 2021
AbstractDiel vertical migration (DVM) of krill was studied throughout 36 h at a fixed station (46.05°S, 66.19°W; 98-m depth) located in the center of the San Jorge Gulf, Southern Patagonia area, during February 2014. Using an echosounder system, combined with an autonomous Video Plankton Recorder (Auto-VPR) and Jacknet samplings, we describe the ...

Modeling patterns of zooplankton diel vertical migration [PDF]

Journal of Plankton Research, 1998
Realized predation pressure, defined as the product of predation pressure and light intensity, expresses the mortality pressure due to visual predation. The part of realized predation pressure which is sensed by organisms is here considered to be related to food level and temperature.

Predicting diel vertical migration of zooplankton [PDF]

Limnology and Oceanography, 1990
Amplitude of diel vertical migration is predicted by water clarity measured by Secchi depth. The model assumes that vertical migration serves to minimize mortality from visually feeding fish and to maximize grazing rate within this predation context. Three of the 24 observations of diel vertical migration are outliers which are either ultraoligotrophic,

A Pilot Study on the Diel Vertical Migration Pattern of Mesopelagic Fishes in the Southern and Central South China Sea

Journal of Marine Science and Engineering
The diel vertical migration of mesopelagic fishes in the southern (S-May station and S-Nov station) and central (C-Jun station and C-Dec station) South China Sea was investigated through a series of continuous field surveys conducted in May, June ...

Diel vertical migration and distribution of zooplankton in a tropical Brazilian reservoir [PDF]

Biotemas, 2009
Diel vertical migration of zooplankton is a strategy usually employed to reduce the risk of predation, and it can also be associated with the environmental day/night shifts, particularly of light and temperature. The aim of this study was to identify the

Diurnal vertical movements in black sea bass (Centropristis striata): Endogenous, facultative, or something else?

Ecosphere, 2021
Fishes commonly exhibit diel rhythms in movements with consequences to feeding, reproduction, predator evasion, and resting. Such behaviors are conceived as plastic, persisting for phases (days to weeks), and then becoming disrupted, masked, and altered ...

Short-term variations of the vertical distribution of cyanobacteria in the open Mediterranean Sea

Scientia Marina, 2000
A general study of biogeochemical processes (DYNAPROC cruise, May 1995) was conducted at a station in the open northwestern Mediterranean Sea where horizontal advection was weak.

Mesozooplankton biodiversity, vertical assemblages, and diel migration in the western tropical Pacific Ocean revealed by eDNA metabarcoding and morphological methods

Frontiers in Marine Science, 2022
Zooplankton plays a crucial role in marine ecosystems. However, due to issues with morphological identification and sampling methods, knowledge of their biodiversity and community structure in the vast pelagic zone of the western tropical Pacific Ocean ...

A Preliminary Study of Suspended Matters Variation Associated with Hypoxia and Shoaling Internal Tides on the Continental Shelf of the Northern Andaman Sea

Journal of Marine Science and Engineering, 2023
The northern Andaman Sea (AS) continental shelf is unique due to the diverse marine ecosystem and existences of both hypoxia and internal tides, but limited in situ observations restrict our understanding of the hydrographic dynamic process. Based on the
