Microbiomes from feces vs. gut in aquatic vertebrates: does the substrate and preservation method matter
Sample type and preservation methods are likely to influence microbiome analysis results. Here, we sampled the same individuals of three aquatic vertebrates from the Qinghai-Tibetan Plateau non-invasively for feces, and subsequently for hindgut through dissection. Our study species, two fishes (Gymnocypris cf. namensis and Triplophysa sp.) and one amphibian (tadpoles of Nanorana parkeri), were all collected at the same time and site. Gut and fecal samples were stored in ethanol, and additionally, part of the gut samples were frozen, but temporarily thawed during transport as it often happens under difficult field conditions.
