The elevated CO(2) concentration at the site for 2 years increased the biomass, the (15)N enrichment and the (15)N recovery in detritivores. This suggests that detritivore consumption was controlled by both the availability of the microbial biomass, a likely major food source, and the ...
Understanding the flow and cycling of matter within food webs is a major objective of contemporary ecosystem research (e.g., Wulff et al. (1989) and literature cited therein). A number of investigations on carbon (C) cycling in pelagic ecosystems focused on the role of the microbial loop (...
Improved analyses of algal δ13C and δ15N combined with quantitative study of organic matter dynamics and food web structure should allow the relative importance of these factors to be distinguished in future food web studies. 展开 关键词: algae, carbon limitation, delta(13)C, energy flow, ...
Keeping and preserving the obtained properties of processed food can be a delicate matter. The product must be treated gently throughout the process. Correct mixing and precise heat treatment is critical to ensure the maximum shelf life and product integrity. And many other process variables must ...
