Interesting new work on bird microbiomes challenging the notion of a lacking signal of phylosymbiosis - www.biorxiv.org/content/10.1...

Host filtering and biogeography structure island bird gut microbiomes

Gut microbiomes are central to host ecology and evolution, yet the mechanisms driv-ing their diversification remain elusive, partly because host evolution and biogeography are often confounded. The re...

The extent to which closely related hosts share similar gut microbiota fascinates me. Work that truely stands out to me comes from @bperezlamarque.bsky.social and colleagues using process-based modelling over correlative approaches - a 'must' read #mevosky academic.oup.com/mbe/article/...

Phylogenetic Comparative Approach Reveals Evolutionary Conservatism, Ancestral Composition, and Integration of Vertebrate Gut Microbiota

Abstract. How host-associated microbial communities evolve as their hosts diversify remains equivocal: how conserved is their composition? What was the com

Rapid establishment of species barriers in plants compared with that in animals

Speciation, the process by which new reproductively isolated species emerge from ancestral populations, results from the gradual accumulation of barriers to gene flow within genomes. To date, the noti...

Using long-term monitoring samples from terrestrial and aquatic ecosystems, we tracked tens of thousands of species across Germany using eDNA, and found no universal loss in local communities, but stronger-than-expected compositional turnover and biotic homogenization at the regional scale.

New preprint reexamining codiversification in mycorrhizal symbioses! 🌱🍄 Spoiler: We found evidence of coevolution, but not cospeciation/codiversification. Congrats Fantine for your great work! 😁
