| Zusammenfassung |
| Stable isotopes have been used extensively to study food-web functioning,
that is, the flow of energy and matter among organisms. Traditional food-web
studies are based on the natural variability of isotopes and are limited to
larger organisms that can be physically separated from their environment.
Recent developments allow isotope ratio measurements of microbes and this in
turn allows the measurement of entire food webs, in other words, from small producers
at the bottom to large consumers at the top. Here, I provide a concise review
on the use and potential of stable isotopes to reconstruct end-to-end food
webs. I will first discuss food web reconstruction based on natural
abundances isotope data and will then show that the use of stable isotopes
as deliberately added tracers provides complementary information. Finally,
challenges and opportunities for end-to-end food web reconstructions in a
changing world are discussed. |
