1. Some definitions

   A Microbiota is a community of microorganisms (Bacteria, Archaea, Fungi and other micro-Eukaryota) living on different supports. If this support is an organism (host), the association host-microbiota is called Holobiont. For example, the human holobiont includes the human organism and all of its particular microbiotas (skin, airway, gut...). Concerning the Microbiome, you could find a definition from Ecology - the science that studies the relationships between living things, and between living things and their habitat (do not confuse habitat with the notion of "ecological niche") - and a definition from Genomics (for more details, do not hesitate to contact me).

2. Analyses performed...

   Generally, input data describe the effect of a particular factor (molecule, physico-chemical parameters) on the Composition and/or Functions of a Microbiota (skin, airway, gut, food, WWTP, river's biofilms...). From these raw data, MicrobiomEcology bioinformatics and statistical analyses will give different conclusions/hypotheses. These analyses can concern Holobionts (Host + Microbiota) or can focus on the Microbiota or on the Host only. Furthermore, MicrobiomEcology guarantees to deliver well-founded hypotheses, even in particular domains: Secondary metabolites and associated metabolic pathways, Microfungi, Mycobiomes...
