The nightscape of the Arctic winter shapes the diving behavior of a marine predator

open access: yesScientific Reports
Predator–prey interactions in marine ecosystems are dynamically influenced by light, as demonstrated by diel vertical migrations of low-trophic level organisms.

Sensitivity of fish diel vertical migration depths to future changes in the Pacific Ocean oxygen minimum zone

open access: yesFrontiers in Marine Science
Diel vertical migrations in the ocean play a key role in predator-prey dynamics and the functioning of the biological carbon pump. However, changes in ocean conditions including warming and deoxygenation threaten to significantly perturb vertical ...

Diel patterns of active vertical migration in seagrass meiofauna

open access: yesMarine Ecology Progress Series, 1986
Patterns of acbve vertical migration exhibited by sediment-associated meiofauna were examlned in a subtropical seagrass meadow. Total numbers, species composition and percentage of sediment meiofauna found to migrate were examined during two 24 h s tudes . Large numbers (>20 000h-' m-2) of harpacticoid copepods representing a substantial proporbon (>50

A new Activity Monitor for Aquatic Zooplankter (AMAZE) allows the recording of swimming activity in wild-caught Antarctic krill (Euphausia superba)

open access: yesScientific Reports
Antarctic krill (Euphausia superba, hereafter krill) is a pelagic living crustacean and a key species in the Southern Ocean ecosystem. Krill builds up a huge biomass and its synchronized behavioral patterns, such as diel vertical migration (DVM ...

Toward predicting Dinophysis blooms off NW Iberia: a decade of events [PDF]

open access: yes, 2016
Dinophysis acuminata and Dinophysis acuta are recurrent species off NW Iberia but their outbreaks occur under different conditions. A decade (2004-2013) of weekly data for each species at two sentinel stations located at the entrance of Rias de Aveiro-AV

Variability in supply and cross-shelf transport of pink shrimp (Farfantepenaeus duorarum) postlarvae into western Florida Bay [PDF]

open access: yes, 2006
The variability in the supply of pink shrimp (Farfantepenaeus duorarum) postlarvae and the transport mechanisms of planktonic stages were investigated with field data and simulations of transport.

Identifying copepod functional groups from species functional traits

open access: yes, 2015
International audienceWe gathered information on the functional traits of the most representative copepod species in the Mediterranean Sea. Our database includes 191 species described by 7 traits encompassing diverse ecological functions: minimal and ...

Diel dynamics of heleoplankton in relation to some physico-chemical attributes of water in an aquaculture tank in Guwahati, Assam [PDF]

open access: yes, 2012
Diurnal fluctuation of the phytoplankton and zooplankton population (numerical densities) and the physicochemical attributes of water are studied in an aquaculture pond at Guwahati, Assam. In the 24 hour diel cycle, the phytoplankton and zooplankton show

Diel Vertical Migration inDaphina Iumholtzi(Sars)

open access: yesJournal of Freshwater Ecology, 2004
ABSTRACT In light of recent studies which suggest that the extreme morphology of Daphnia lumholtzi (Sars) does not effectively deter all vertebrate predators, we sought to determine if this species exhibits behavioral responses that, may minimize planktivory by fish.
