Museum specimens reveal evolutionary drivers and functions of oral microbiome in mammals

The paper analyzes oral microbiomes from museum specimens to show that diet drives oral microbiome evolution and some microbes have ancient origins.

Dental calculus as a record of Pleistocene reindeer oral, digestive and dietary flora

This study analyzes dental calculus from Pleistocene and modern reindeer to reconstruct their oral microbiomes, digestive microbiomes, and diets using ancient metagenomics.

Host-gut microbiota interactions shape parasite infections in farmed Atlantic salmon

The paper investigates how host genetics and gut microbiota interact with parasite infections in Atlantic salmon, finding that cestode infections alter microbiota composition and host gene expression.

A paleogenomic investigation of overharvest implications in an endemic wild reindeer subspecies

This study investigates genetic changes in Svalbard reindeer due to historical overharvesting using ancient and modern genomes, showing reduced genetic diversity and altered allele frequencies.

Uncovering the hologenomic basis of an extraordinary plant invasion

The paper investigates the genomic basis of invasiveness in Ambrosia artemisiifolia, finding selection signatures in defense genes and reduced pathogen prevalence in invasive populations.
