Decrease of the biotic diversity with increasing latitude is one of the most universal macroecological pattern that has been observed on broad range of taxa including parasites and pathogens associated with animal hosts. However, there are almost no empirical studies focused on latitudinal variation in gut microbiota (GM). Here we provide analyses on the GM composition and diversity in 81 passerine species sampled in temperate (Czech Republic) and tropical (Cameroon) populations. Metataxonomic approach based on 16S rRNA sequencing and phylogenetically controlled Markov Chain Monte Carlo simulations revealed that there is only slight GM diversity increase in tropical compared to temperate species. However, pronounced differences between tropical and temperate population in GM composition were detected, with Firmicutes bacteria being overrepresented in tropical populations. Although GM composition of trans-Saharan migrants differed from GM of residents and short-distance migrants, there was not higher GM similarity between tropical species vs. trans-Saharan migrants then between tropical species vs. temperate residents and short-distance migrants. In addition, we observed GM differentiation between tropical and temperate populations and due to migration behavior. According to our data, differences between trans-Saharan migrants vs. residents or shortdistance migrants are unlikely to arise as a consequence of environmental bacteria sampling at wintering grounds.
