Top-down and bottom-up jellyfish on primary productivity planktonic assemblages
2014/4/17
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...
Diel vertical migration of the deep-water jellyfish Periphylla periphylla simulated as individual responses to absolute light intensity
he deep-water jellyfish Periphylla periphylla simulated absolute light intensity
2014/4/17
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 ...
