Gut microbiota variation between climatic zones and due to migration strategy in passerine birds.

ABSTRACT:

Introduction

Decreasing biotic diversity with increasing latitude is an almost universal macroecological pattern documented for a broad range of taxa, however, there have been few studies focused on changes in gut microbiota (GM) across climatic zones.

Methods

Using 16S rRNA amplicon profiling, we analyzed GM variation between temperate (Czechia) and tropical (Cameroon) populations of 99 passerine bird species and assessed GM similarity of temperate species migrating to tropical regions with that of residents/short-distance migrants and tropical residents. Our study also considered the possible influence of diet on GM.

Results

We observed no consistent GM diversity differences between tropical and temperate species. In the tropics, GM composition varied substantially
