Metagenomic analyses of gut microbiome composition and function with age in a wild bird; little change, except increased transposase gene abundance
Abstract. Studies on wild animals, mostly undertaken using 16S metabarcoding, have yielded ambiguous evidence regarding changes in the gut microbiome (GM)
academic.oup.com
Our new paper, using shotgun metagenomics on the gut microbiome, shows small but interesting longitudinal changes with age in a natural population.

New research by our scientists suggests that matching environmental adaptations during genetic rescue of endangered species offers the best outcomes, but it is not always required for successful conservation.
