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...

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 ...
