Dear Mário,

below I put some papers that hopefully will be inspiring for you.

Mayntz et al 2005 and Kohl et al 2015 use the framework of nutritional geometry but similar question, however focused on ecosystem functioning, not on an organism, may be asked using the framework of ecological stoichiometry. I suggest including more elements than just C, N and P because predators should not experience high "stoichiometric mismatches" considering N and P, other elements may be limiting for predators. The easiest way of comprehensive detection of stoichiometric mismatches is use of TSR index, since it does not require performing feeding trials in growing animals. You will find descriptions of TSR in Filipiak and Weiner 2014 and Filipiak et al 2016.

(I added external links, since there is a problem with Reasearchgate internal links, sorry for doing mess.)

Kind regards!

Dear Michal,

Thank you very much for your answer. I will read the articles that you have suggested.

With my best regards

Mario

Dear Abhishek Raj,

Thank you very much!

Best regards

Mario

Dear Mário,

Michał pointed out already to a lot of relevant literature. So I don't repeat those here, but attach some articles that dealt specifically with fish and ecological stoichiometry.

Because Michał also mentioned papers from nutritional geometry framework, I also attach one of my recent papers that attempts to bridge ecological stoichiometry with nutritional geometry as related and complementary frameworks in nutritional ecology.

Best regards,

Erik

Dear Erik,

Thank you for your attention for sending your references. I will sudy all of them and as soon as possible I will get in contact to discuss with you and the others coleagues about this interesting subject.

With my best regards

Mario

Hi Mario

there is another thread on this topic here on RG:

 Hi Gregor,

Thank you very much for your atention. Yes, it is a very interesting subject. Soon I will get in contact.

Best regards

Mario
