Jellyfish distribute vertically according to irradiance [PDF]

Journal of Plankton Research, 2017
We tested the hypothesis that the coronate jellyfish Periphylla periphylla distributes vertically according to a preferential range of absolute light intensities. The study was carried out in Lurefjorden, Norway, a fjord characterized by mass occurrences of this jellyfish. We collected data on the vertical distribution of P.

Mill dams impact microbiome structure and depth distribution in riparian sediments

Frontiers in Microbiology, 2023
IntroductionDamming has substantially fragmented and altered riverine ecosystems worldwide. Dams slow down streamflows, raise stream and groundwater levels, create anoxic or hypoxic hyporheic and riparian environments and result in deposition of fine ...
