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...
A manipulative mesocosm experiment was done in a saline coastal lake in Australia to compare the top-down and bottom-up influences of jellyfish on primary production and planktonic assemblages. We hyp...
New research led by University of Queensland and CSIRO Climate Adaptation Flagship scientist, Dr Anthony Richardson presents convincing evidence that this "jellyfish joyride" is associated with over-f...
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 ...
Vertical migration of the mesopelagic jellyfish Periphylla periphylla (Scyphozoa: Coronatae) was studied by use of hull-mounted and submerged echosounders in a ~440 m deep Norwegian fjord. The researc...
Laid Bare Seafloor in South Pacific Ocean Devoid of Sediment.A bare zone at the bottom of the central South Pacific Ocean is completely devoid of sediment, marine geologist David Rea of the University...
Data obtained since 1958 from the continuous plankton recorder show an increasing occurrence of jellyfish in the central North Sea that is positively related to the North Atlantic Oscillation (NAO) an...
In December 2002, large numbers of dead jellyfish, Crambionella orsini, were observed on the seabed over a wide area of the Arabian Sea off the coast of Oman at depths between 300 m and 3,300 m. Morib...
