Comparative ecology of the macrofauna of freshwater and marine muds1 [PDF]

Limnology and Oceanography, 1988
There are many striking similarities between the benthic macrofauna inhabiting marine and lacustrine sediments. Most of the same trophic/functional groups are well represented in both habitats. There is no obvious difference between the types of particulate food sources available for microphagous animals.

Oxic-anoxic regime shifts mediated by feedbacks between biogeochemical processes and microbial community dynamics

Nature Communications, 2017
The role of microbial communities in regime shifts is poorly understood. Here, the authors use a mathematical model and field data from a seasonally stratified lake to show that gradual environmental changes can induce oxic-anoxic regime shifts mediated ...

A Deep-Sea Sponge Loop? Sponges Transfer Dissolved and Particulate Organic Carbon and Nitrogen to Associated Fauna

Frontiers in Marine Science, 2021
Cold-water coral reefs and sponge grounds are deep-sea biological hotspots, equivalent to shallow-water tropical coral reefs. In tropical ecosystems, biodiversity and productivity are maintained through efficient recycling pathways, such as the sponge ...

Meta-transcriptomic comparison of two sponge holobionts feeding on coral- and macroalgal-dissolved organic matter

BMC Genomics, 2022
Background Sponge holobionts (i.e., the host and its associated microbiota) play a key role in the cycling of dissolved organic matter (DOM) in marine ecosystems.
