Modeling patterns of zooplankton diel vertical migration [PDF]

open access: yesJournal 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]

open access: yesLimnology 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,

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

open access: yesEcosphere, 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 ...

Programming Simulations of Diel Vertical Migration Behavior of Zooplankton [PDF]

open access: yes, 2021
Diel vertical migration of zooplankton is the daily cycle of movement towards and away from the surfaceof a lake that results from the need to avoid predation and forage for food.The process of diel vertical migration is one of the main forces creating ...

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

open access: yesBiotemas, 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

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

open access: yesScientia 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

open access: yesFrontiers 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

open access: yesJournal 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

The effects of Najas marina on the zooplankton species composition and water chemistry in a small, shallow lake (Fehér-tó, Fertő-Hanság National Park, Hungary) [PDF]

open access: yesOpuscula Zoologica Instituti Zoosystematici et Oecologici Universitatis Budapestinensis, 2006
Horizontal distribution and diurnal migration of zooplankton as well as a few water chemistry parameters were investigated in the clear-water and the turbid state of the extremely shallow Lake Fehér (Hungary) between 1998-2001. Significant horizontal and
