I m looking for some literature that describes the method to measure the trophic level transfer efficiency in marine ecosystems directly on the field in-situ.
Hello. Have you had the opportunity to read the chapter "Bevelhimer, M.S. and Breck, J.E. (2009) Centrarchid Energetics, in Centrarchid Fishes: Diversity, Biology, and Conservation (eds S. J. Cooke and D.P. Philipp), Wiley-Blackwell, Oxford, UK, doi: 10.1002 / 9781444316032.ch7"?
