Objective:

To investigate the correlations between biotic and abiotic factors and the skin bacteria of amphibians.

Approach:

• Study Design: The research involved swab samples from 2,349 amphibians across 205 species, utilizing DNA sequencing to identify skin bacteria.
• Statistical Analysis: Various statistical and modeling approaches were employed to assess the correlation between skin bacteria and environmental factors.

Key Findings:

• Amphibians exhibited more diverse skin microbiomes in regions with colder winters and more variable annual temperatures, according to the study.
• The study suggests that warmer climates may lead to rapid bacterial growth, reducing microbial diversity.

Interpretation:

The study provides insights into how environmental factors impact amphibian skin bacteria.

Conclusion:

The study presents findings on the relationship between climate and skin microbiome diversity in amphibians.
