Variations on the diversity of amphibian skin microbiota across forests fragments

The skin of amphibians acts as first barrier of protection against invading microorganisms. Besides the mechanical components, this protection probably include biochemical and biological mechanisms derived from both the resident microbial community and the secretion of bioactive molecules from dermal glands. The aims of this study were to characterize the microbial community hosted by Proceratophrys boiei and analyse its relationship with environmental microbial communities; evaluate the stability of these through different populations in forest fragments.

两栖动物的皮肤是抵御入侵微生物的第一道防御屏障。除机械防御组分外，该防御体系或涵盖源自常驻微生物群落与皮肤腺体分泌的生物活性分子的生化及生物学防御机制。本研究旨在对布氏角蟾（Proceratophrys boiei）体表定殖的微生物群落进行特征解析，并探究其与环境微生物群落的关联；同时评估森林片段内不同种群中该群落的稳定性。
