Seasonal depth and temperature use, and diel movements of lake trout (Salvelinus namaycush) in a subarctic lake

Arctic Science, 2019
We conducted a multi-year acoustic telemetry study of lake trout (Salvelinus namaycush (Walbaum, 1792)) in a small subarctic lake to investigate depth and temperature occupancy, and vertical activity across seasons (summer, fall, and winter), diel ...

Interpreting vertical movement behavior with holistic examination of depth distribution: a novel method reveals cryptic diel activity patterns of Chinook salmon in the Salish Sea

Animal Biotelemetry, 2017
Aquatic organisms exhibit a variety of diel changes in vertical movement that are investigable through the use of biotelemetry. While certain species do not change their movements between day and night, others exhibit diel vertical migration (DVM) or a ...

Bioenergetic evaluation of diel vertical migration by bull trout

I evaluated hypotheses related to growth as a driver of depth use and diel vertical migration by bull trout (Salvelinus confluentus) in a thermally stratified reservoir.

Plankton vertical migrations - Implications for the pelagic ecosystem [PDF]

, 2011
Habitat selection is an important behavior of many organisms. The direction and strength of this behavior is often characterized as a result of a trade off between predator avoidance and obtaining resources. A characteristic example of this trade off may

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 ...

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

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

, 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 ...

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.
