We measured diel migration with 11 acoustic Doppler current meter profilers and consistently found diel and lunar cycles of vertical migration from 250 m down to the bathypelagic (> 1000 m). These mea...

2014/4/2
In an intensive study of the vertical and horizontal distribution of zooplankton in a eutrophic lake (Katepwa
Lake), we found that only adult Leptodora kindtii (. 5 mm in body size) exhibited diel ve...

We examined the diel behavior among the jellyfish Periphylla periphylla in Lurefjorden, Norway in a sampling
campaign and by a . 3-month continuous acoustic study. Jellyfish distribution and behavior...
Toward a more comprehensive theory of zooplankton diel vertical migration: Integrating ultraviolet radiation and water transparency into the biotic paradigm

2014/4/4
The current prevailing theory of diel vertical migration (DVM) of zooplankton is focused largely on two biotic drivers: food and predation. Yet recent evidence suggests that abiotic drivers such as da...
Survival probability of larval sprat in response to decadal changes in diel vertical migration behavior and prey abundance in the Baltic Sea

2014/4/17
We employed a coupled three-dimensional biophysical model to explore long-term inter- and intra-annual variability in the survival of sprat larvae in the Bornholm Basin, a major sprat spawning area in...
Zooplankton vertical migration and plasticity of pigmentation arising from simultaneous UV and predation threats
Zooplankton vertical migration plasticity of pigmentation arising simultaneous UV predation threats
font style='font-size:12px;'>
2014/4/17
We assessed how zooplankton (copepods) handle the simultaneous threats of predators and ultraviolet (UV) radiation and whether they respond with changes in pigmentation, vertical migration, or both. W...

2014/4/17
Vertical distribution and abundance of three numerically dominant krill species (Nyctiphanes simplex,
Nematoscelis difficilis, and Euphausia eximia) were surveyed in the Gulf of California to underst...
Comparison of zooplankton vertical migration in an ice-free and a seasonally ice-covered Arctic fjord: An insight into the influence of sea ice cover on zooplankton behavior

2014/4/16
We present observations of zooplankton diel vertical migration (DVM) over a period of 2 yr in an ice-free and
a seasonally ice-covered Arctic fjord. The contrasting environments permitted assessment ...

In many lakes, zooplankton show a distinct diel vertical migration (DVM) behavior, especially during periods
of stratification. Excretion products of these zooplankton could potentially cause an upwa...

2014/4/18
The intensity and spectral composition of visible light are known to influence fish predation on zooplankton.
However, in clear-water systems, ultraviolet (UV) radiation (UVR) may also influence fish...

We evaluate the hypothesis that the vertical migration of Periphylla periphylla is governed by its sensitivity to
light intensity. By applying an individual-based model where random walk is combined ...
