Hypothesis

Is there a 'guanophilic' community in Arcellinida?

Conclusion

Guano-enriched sites foster higher Arcellinida diversity and abundance, while caves without guano host communities that are subsets of external populations.

Supporting Evidence

  • Communities in guano-rich sites displayed higher diversity and abundance.
  • Unique OTUs and genetic variants were found in guano-impacted sites.
  • Sites without guano hosted communities with low abundance and reduced biodiversity.

Takeaway

Bats help create a rich environment for tiny creatures called Arcellinida in caves by leaving behind their droppings, which provide food and nutrients.

Methodology

Sediment samples were collected from two independent hydrosystems and a metabarcoding approach was used to assess Arcellinida diversity.

Potential Biases

Potential bias in sampling locations may affect the generalizability of the findings.

Limitations

The study may not capture all Arcellinida diversity due to the specific sampling methods and locations.
