Environmental DNA for Aquatic Monitoring: Impact of Diel Vertical Migration

Environmental DNA
There is increasing interest in using eDNA for deriving abundance indices for biodiversity monitoring and in support of fisheries management. However, eDNA concentrations are affected by animal behavior, such as diel vertical migration, which has ...

Diel vertical migration and spatial overlap between fish larvae and zooplankton in two tropical lakes, Brazil

Brazilian Journal of Biology
The effect of fish larvae on the diel vertical migration of the zooplankton community was investigated in two tropical lakes, Finado Raimundo and Pintado lakes, Mato Grosso do Sul State, Brazil.

Diel vertical migration of Arctic zooplankton during the polar night [PDF]

, 2009
High-latitude environments show extreme seasonal variation in physical and biological variables. The classic paradigm of Arctic marine ecosystems holds that most biological processes slow down or cease during the polar night.

Models on diel vertical migration [PDF]

, 1993
To clarify what can be expected from models the role of modelling in the scientific process in relation to experiments and field studies is addressed. Hypotheses to explain vertical migration are reviewed with respect to the selection mechanism assumed ...

Vertical migration in Chaoborus flavicans in the absence and presence of diel light cycles.

, 1993
Diel vertical migration in zooplankton communities has been extensively studied for well over a century, yet factors affecting this phenomenon are not well understood. Light as a cue for vertical migration in the dipteran Chaoborus flavicans was examined

Moonlight drives ocean-scale mass vertical migration of zooplankton during the Arctic winter [PDF]

, 2016
The creation of the pan-Arctic archive of ADCP data was supported by the UK Natural Environment Research Council (NERC) (Panarchive: NE/H012524/1 and SOFI: NE/F012381/1) as was mooring work in Svalbard (Oceans 2025 and Northern Sea Program).

Extensive oceanic mesopelagic habitat use of a migratory continental shark species

Scientific Reports, 2022
The identification of movement and behaviour patterns, as well as inter- and intra-population connectivity is crucial in order to implement effective and functional management and conservation measures for threatened migratory species such as tope ...

Vertical Distribution Patterns of Cephalopods in the Northern Gulf of Mexico

Frontiers in Marine Science, 2020
Cephalopods are important in midwater ecosystems of the Gulf of Mexico (GOM) as both predator and prey. Vertical distribution and migration patterns (both diel and ontogenic) are not known for the majority of deep-water cephalopods.

Fine-scale vertical structure of sound-scattering layers over an east border upwelling system and its relationship to pelagic habitat characteristics [PDF]

Ocean Science, 2020
Understanding the relationship between sound-scattering layers (SSLs) and pelagic habitat characteristics is a substantial step to apprehend ecosystem dynamics. SSLs are detected on echo sounders representing aggregated marine pelagic organisms.

Diel variability in the vertical distribution of coastal barnacle larvae in the Bay of Cartagena, Chile

Revista Chilena de Historia Natural, 2023
Background Vertical distribution of zooplankton is an important biological factor that can modulate zooplankton transport, dispersal, and survival in the ocean.
