Greater trophic diversity of soil animal communities under agricultural land use and tropical climate Soils are the most biodiverse habitats on Earth contributing to about 59% of global biodiversity1. Approximately 90% of the carbon fixed by plants in terrestrial ecosystems enters the belowground system2 and is processed in soil food webs by microorganisms and invertebrate decomposers, with the latter serving as prey for predators3,4. Soil food webs are characterized by major energy fluxes in terrestrial ecosystems and trophic interactions among an exceptionally diverse spectrum of organisms with different niches. Consequently, soil food webs are of essential importance for carbon and nitrogen cycling and thereby for ecosystem functions and services5. Beyond belowground processes, trophic interactions of soil organisms extend to the biodiversity and functionality of the aboveground system, fostering feedback loops between aboveground and belowground compartments of terrestrial ecosystems3,6,7. It has been shown that the functional diversity of soil animals (rather than species richness alone) is closely associated with litter decomposition, carbon and nutrient cycling and plant growth8,9,10,11. The diversity of functions driven by soil animals in food webs is based on their trophic diversity, defined as the heterogeneity of trophic niches (including basal resources and trophic levels) across soil animal individuals and taxa5,8. Trophic diversity offers insight into community structure and function beyond taxonomic...

Fig. 1 Diagram showing the different aspects of biodiversity that studies may focus on. Rodents in the botton left circle may be the primary reservoirs of a pathogen, but other species may be important competitors (botton right circle) or predators (top circle) that can affect the population dynamics, behavior, and contact rate of focal species. Further, additional species may introduce other pathogens into a community that interact directly or indirectly with the pathogen of interest.

Hi bluesky, I'm new here! 👋🏼🦋

I’m a PhD student in Dr Mike Fox's Ecological Oceanography Lab at #KAUST 👩‍🔬 My research aims to understand how oceanographic processes impact #coral #physiology and #trophic #ecology in the Red Sea 🌊🪸

Looking forward to sharing my journey & connecting with you! :)
