Dear colleagues
I am writing because I wonder which method to use to study the impact of cormorants guano on soil animal food webs. I want to get to know which animal feed on guano. Firstly, I thought to use carbon and nitrogen isotopes, but I heard about fatty acids.
Which method will be best for this study?
Best regards

Both carbon and nitrogen isotopes and fatty acid analysis can be useful methods for studying food webs in soil biota in cormorant colonies. Here are some considerations for each method:
Carbon and nitrogen isotopes:
- Carbon and nitrogen isotopes can be used to track the flow of nutrients through food webs.
- This method involves analyzing the stable isotopes of carbon and nitrogen in the tissues of organisms to determine their position in the food chain.
- This approach can help identify which organisms are consuming guano and how guano-derived nutrients are being incorporated into the soil food web.
- However, the interpretation of stable isotope data can be complex and requires careful consideration of factors such as trophic fractionation and baseline values.
Fatty acid analysis:
- Fatty acid analysis can be used to identify specific food sources for soil biota.
- This method involves analyzing the fatty acid profiles of organisms to determine the sources of their food.
- This approach can help identify which organisms are consuming guano and the extent to which guano-derived nutrients are being incorporated into the soil food web.
- However, the interpretation of fatty acid data can also be complex and requires careful consideration of factors such as diet variability and the influence of environmental factors.
Both of these methods can provide valuable insights into the food webs of soil biota in cormorant colonies. Ultimately, the choice of method may depend on factors such as the specific research questions, the availability of resources and expertise, and the specific characteristics of the soil biota community being studied.
