Vertical distribution of zooplankton in a shallow peatland pond: the limiting role of dissolved oxygen [PDF]
, 2013 We investigated the diel vertical distribution patterns of microcrustacean zooplankton (Cladocera, Copepoda) in a shallow pond (max. depth: 70 cm) of the Öreg-turján peatland (Ócsa, Central Hungary) during three 24-h periods in July (19–20th), August (17–

Migratory Zooplankton Excreta and Its Influence on Prokaryotic Communities
Frontiers in Marine Science, 2020 Particulate organic matter (POM) (fecal pellets) from zooplankton has been demonstrated to be an important nutrient source for the pelagic prokaryotic community.

Frontiers in Marine Science, 2021 Calanus sinicus, a temperate copepod with a lethal temperature >27°C, is one of the key species in Chinese coastal marine ecosystems. The C. sinicus population increases in spring and declines in early summer annually due to increasing water ...

Predator-enhanced diel vertical migration in a planktonic dinoflagellate [PDF]
Marine Ecology Progress Series, 2012 Diel vertical migration (DVM) is a common and conspicuous behavior amongst planktonic organisms. In the case of dinoflagellates, both light and nutrients have been shown to regulate DVM, although the role of predators (grazers) has been understudied. Here we report the results of an experimental study using a system of 'plankton mini-towers' to examine

Evidence of Diel Vertical Migration of Mesopelagic Sound-Scattering Organisms in the Arctic
Frontiers in Marine Science, 2017 While sound scattering layers (SSLs) have been described previously from ice-covered waters in the Arctic, the existence of a viable mesopelagic community that also includes mesopelagic fishes in the Arctic has been questioned.

The Demographic Benefits of Diel Vertical Migration by Zooplankton [PDF]
Ecological Monographs, 1990 Three types of diel vertical migration behavior were expressed within a fjord population of the calanoid copepod Pseudocalanus newmani: (1) reverse migration (nocturnal descent), (2) normal migration (nocturnal ascent), and (3) no detectable migration. Reverse migration by P. newmani occurred in all three study years, but only at a deep (185 m) station

Contrasting diel vertical migration patterns in Salpa fusiformis populations [PDF]
Journal of Plankton Research, 2017 7 pages, 2 figures, 1 table Vertically stratified zooplankton sampling at three locations in the Catalan Sea demonstrated that the coexistence of two diel vertical migration patterns in Salpa fusiformis populations. Salps migrated to the surface during the day (reverse migration) at one station while they swam to surface layers at night (nocturnal ...

Models on diel vertical migration
, 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; it is asked whether group selection instead of individual selection arguments are used explicitly or

Diel Vertical Migrators Respond to Short‐Term Upwelling Events
Geophysical Research LettersPelagic organisms inhabiting coastal upwelling regions face a high risk of advection away from the nearshore productive habitat, potentially leading to mortality.
