Hi food web colleagues, diet experts...etc
Our last project started from the crazy idea to build a comprehensive benthic topology food web for the whole North Sea. It quickly seemed impractical for only a few human-beings as we lack data for most non-commercial species. It took almost two years to focus on 152 species, project that got reduced to 50 or so species for practicality.
We still want to go for it but I think we need to find the right people who might have the diet data we need or know where to find them (in situ, lab feeding experiments, published or unpublished data, or inference from other species).
Do you have diet information on species in the North Sea? Know someone who does? We could start from there.

Abhijit Mitra Thanks for sharing. I know that study very well for citing it and having Ingrid on board our study. :)
It is a great study and I used some of their information but they use stable isotope which doesn't inform on who eats whom (the links) but more who is above whom in the food web (the position).
It give insights in the structure but you cannot apply network analysis on it.
Hi Pierre!
How it's been since Villefranche?
I do not know if you plan to include zooplankton in there but i've got that paper from the english channel (but i think it is fairly applicable to north sea at least in the great lines):Article High prey-predator size ratios and unselective feeding in co...
(i'm sorry for the colors they are ugly but i was begining with R graphics!)
If you want to go further you can look at the references cited in there or you can contact me i should be able to point you to the main references on zooplankton feeding ecology in the north sea
I actually have to create a comprehensive food Web during my final year at university, I would love to try and help 9ut with this.
Thanks Nicolas Djeghri You know, working on my PhD :D
We do not have a more detailed box than just "zooplankton", unfortunately but always good to have such paper.
Might identify a few links between that box and species.
I also included papers from the English Channel so if you have others, send them in.
Kain Waring You should check our supplementary and my older paper in oikos. We listed some do's and don'ts regarding building food webs :)
