Hi folks,
I am looking for a reference that compares primary production across different ecosystems (marine vs terrestrial vs freshwaters). Especially, including streams (maybe even headwaters my research focus). I did a quick research and I cannot find anything answering my question within one study. Does someone has something in mind for me?
You will have to do a meta analysis and account for bias, such as different methodologies and duration of studies :)
As I started to think about it... mesuring riverine productivity is very complex, compared to terrestrial.
I found something interesting:
Light and flow regimes regulate the metabolism of rivers (https://doi.org/10.1073/pnas.2121976119)
But there they all focus on productivity and not on production itself. So how much biomass is available at the trophic base by numbers is still not so clear.
Hi Nadine Ebm ,
Measuring primary productivity is more challenging in the marine environment than in a riverine ecosystem due to the changing environment. The riverine ecosystem is more complex than a terrestrial ecosystem. This is due to the stable microenvironment.
