Symbioses shape feeding niches and diversification across insects - Nature Ecology & Evolution Insects rely on symbiotic microbes for nutrition and defence. Analysing a large dataset of microbe–insect symbioses, the authors show that symbiosis evolved in response to nutrient deficiencies but it...

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...

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

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

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/...

Hibecovirus (genus Betacoronavirus) infection linked to gut microbial dysbiosis in bats Abstract. Little is known about how zoonotic virus infections manifest in wildlife reservoirs. However, a common health consequence of enteric virus infect

Did you know coronavirus infections impact the gut microbial community of #bats? But the effect differs between viruses. Published in @ismepublications.bsky.social - Big team effort: @alice-risely.bsky.social @cdrosten.bsky.social @vmcorman.bsky.social et al. academic.oup.com/ismecommun/a...

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...

Check out this cool work from @crouxevo.bsky.social and others, congrats!!! 🥳

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! 😁

Negative global-scale association between genetic diversity and speciation rates in mammals - Nature Communications Genetic diversity and speciation rate support adaptability and species richness patterns, respectively. Here, the authors find a negative association between mitochondrial genetic diversity and specia...

Last first-author paper finally published! This took too many years but even after leaving research we manage to get it done, with Odile Maliet, @leandrist.bsky.social, @noguesbravo.bsky.social, @n8upham.bsky.social, Walter Jetz, and really supportive Hélène Morlon
