Microbiome of the sexual scent organ of Leptonycteris yerbabuenae

Microorganisms are tightly bounded to the animals on Earth. Bacteria, among other types of microbes, interact with their hosts in several ways regarding metabolic pathways, development, complex behavioral processes such as mate recognition, among others. The adult males of Leptonycteris yerbabuenae, a nectarivorous bat, develop an interscapular odoriferous patch during the mating season. Here we present a description of the microbiota associated to this sebaceous patch 11 adult males, and studied it in terms of their taxonomical information. The variability between samples was not relevant to this study, and the most abundant phyla were Firmicutes and Proteobacteria, with dominanting classe…

Database of diazotrophs in global ocean: abundance, biomass and nitrogen fixation rates

Marine N<sub>2</sub> fixing microorganisms, termed diazotrophs, are a key functional group in marine pelagic ecosystems. The biological fixation of dinitrogen (N<sub>2</sub>) to bioavailable nitrogen provides an important new source of nitrogen for pelagic marine ecosystems and influences primary productivity and organic matter export to the deep ocean. As one of a series of efforts to collect biomass and rates specific to different phytoplankton functional groups, we have constructed a database on diazotrophic organisms in the global pelagic upper ocean by compiling about 12 000 direct field measurements of cyanobacterial diazotroph abundances (based on microscopic …

Geographical separation and physiology drive differentiation of microbial communities of two discrete populations of the bat Leptonycteris yerbabuenae

In this paper, we explore how two discrete and geographically separated populations of the lesser long‐nosed bat (Leptonycteris yerbabuenae)—one in central and the other in the Pacific region of Mexico—differ in their fecal microbiota composition. Considering the microbiota–host as a unity, in which extrinsic (as food availability and geography) or intrinsic factors (as physiology) play an important role in the microbiota composition, we would expect differentiation in the microbiota of two geographically separated populations. The Amplicon Sequences Variants (ASVs) of the V4 region of the 16s rRNA gene from 68 individuals were analyzed using alpha and beta diversity metrics. We obtained a …
