Egg microbiota is the starting point of hatchling gut microbiota in the endangered yellow‐spotted Amazon river turtle

Abstract:

Establishment and development of gut microbiota during vertebrates' early life are likely to be important pbkp_redictors of health and fitness. Host‐parental and host‐environment interactions are essential to these processes. In oviparous reptiles whose nests represent a source of the parent's microbial inocula, the relative role of host‐selection and stochastic environmental factors during gut microbial assemblage remains unknown. We sampled eggs incubated in artificial nests as well as hatchlings and juveniles (up to 30 days old) of the yellow‐spotted Amazon river turtle (Podocnemis unifilis) developing in tubs filled with river water. We examined the relative role of the internal egg microbiota and the abiotic environment on hatchling and juvenile turtle's cloacal microbiota assemblages during the first 30 days of development. A mean of 71% of ASVs in hatched eggs could be traced to the nest environmental …
