1 Trophic interactions, organic matter, and nutrient cycling

Mittwoch, 13:00-14:30, H 36

Stable isotopes have revolutionized our understanding of trophic interactions and symbiosis in terrestrial and aquatic ecosystems. The use of isotopes enables the identification of food resource usage, trophic position within food webs, and geographic location of organisms. Isotope tracers are crucial to elucidating fluxes of nutrients through food webs, while bulk and compound-specific isotope analyses are essential for investigating trophic interactions within ecosystems. Deciphering trophic structures and resource partitioning has yielded vital insights into interactions within and between communities, their functions, and their vulnerability to disturbances.

We welcome contributions on new insights into trophic and symbiotic interactions and on the latest methodological developments for identifying and quantifying interactions within food webs and the linkages between organisms in terrestrial and aquatic ecosystems.
