Diel vertical migration and distribution of zooplankton in a tropical Brazilian reservoirlian

open access: yesBiotemas, 2009
Migração vertical e distribuição do zooplâncton em um açude tropical brasileiro. A migração vertical diária do zooplâncton é uma estratégia geralmente utilizada para reduzir o risco de predação, mas que pode também se associar às mudanças de dia/noite ...

Shark predation on migrating adult American eels (Anguilla rostrata) in the Gulf of St. Lawrence. [PDF]

open access: yesPLoS ONE, 2012
In an attempt to document the migratory pathways and the environmental conditions encountered by American eels during their oceanic migration to the Sargasso Sea, we tagged eight silver eels with miniature satellite pop-up tags during their migration ...

Migration of Net Phytoplankton and Zooplankton in Mendum’s Pond, New Hampshire [PDF]

open access: yes, 2006
The study examines the vertical distribution and migratory behavior of net phytoplankton and zooplankton of Mendum’s Pond in Barrington, N.H. The cyanobacteria, Microcystis and Aphanocapsa were the dominant net phytoplankton in this lake.

Phytoplankton Tune Local pH to Actively Modulate Circadian Gravitactic Behavior

open access: yesAdvanced Physics Research
Diel vertical migration (DVM) is the daily movement of motile phytoplankton between light‐rich surface waters and deeper nutrient‐rich layers, typically governed by internal clocks. However, many species show irregular patterns that deviate from expected

Evidence of the selection of tidal streams by northern rock sole (Lepidopsetta polyxystra) for transport in the eastern Bering Sea [PDF]

open access: yes, 2009
Depth data from archival tags on northern rock sole (Lepidopsetta polyxystra) were examined to assess whether fish used tidal currents to aid horizontal migration.

Uncovering intra-daily intertidal biofilm dynamics in a shorebird foraging hotspot with hourly UAV multispectral imagery acquisitions

open access: yesInternational Journal of Applied Earth Observations and Geoinformation
Estuarine mudflats are colonized by biofilm-forming microphytobenthos (MPB), which support primary production, stabilize sediment, and provide critical food for benthic invertebrates and shorebirds.

The influence of sea ice, wind speed and marine mammals on Southern Ocean ambient sound [PDF]

open access: yesRoyal Society Open Science, 2017
This paper describes the natural variability of ambient sound in the Southern Ocean, an acoustically pristine marine mammal habitat. Over a 3-year period, two autonomous recorders were moored along the Greenwich meridian to collect underwater passive ...

On drift and diel vertical migration of bottom invertebrates of the Amur. [Translation from: Zoologicheskie Zhurnal 42 1601-1612, 1963.] [PDF]

open access: yes, 1963
Planktobenthos was sampled in 1957-58 in the river Amur. A determination of the kind of organisms drifting in the mass of water of the Amur was carried out.
