DOI: 10.1038/s42003-019-0689-7
Abstract: Nearly all lineages of birds host parasitic feather lice. Based on recent phylogenomic studies, the three major lineages of modern birds diverged from each other before the Cretaceous-Paleogene (K-Pg) mass extinction event. In contrast, studies… read more here.

Ancient Occasional Host Switching of Maternally Transmitted Bacterial Symbionts of Chemosynthetic Vesicomyid Clams
Sign Up to like & getrecommendations! Published in 2017 at "Genome Biology and Evolution"
DOI: 10.1093/gbe/evx166
Abstract: Abstract Vesicomyid clams in deep-sea chemosynthetic ecosystems harbor sulfur-oxidizing bacteria in their gill epithelial cells. These symbionts, which are vertically transmitted, are species-specific and thought to have cospeciated with their hosts. However, recent studies indicate… read more here.

DOI: 10.1093/gigascience/giae004
Abstract: Abstract Background Lice (Psocodea: Phthiraptera) are one important group of parasites that infects birds and mammals. It is believed that the ancestor of parasitic lice originated on the ancient avian host, and ancient mammals acquired… read more here.

DOI: 10.1093/sysbio/syad022
Abstract: Speciation via host-switching is a macroevolutionary process that emerges from a microevolutionary dynamic where individual parasites switch hosts, establish a new association, and reduce reproductive contact with the original parasite lineage. Phylogenetic distance and geographic… read more here.

DOI: 10.1093/zoolinnean/zlaf101
Abstract: This study provides an updated molecular phylogeny of Iphitime Marenzeller, 1902 (Annelida: Dorvilleidae), a group of symbiotic dorvilleid polychaetes, including a topotypic specimen of the type species, Iphitime doederleini Marenzeller, 1902. Also, a new species,… read more here.

Host switching by an ambrosia beetle fungal mutualist: Mycangial colonization of indigenous beetles by the invasive laurel wilt fungal pathogen.

DOI: 10.1111/1462-2920.16401
Abstract: Ambrosia beetles require their fungal symbiotic partner as their cultivated (farmed) food source in tree galleries. While most fungal-beetle partners do not kill the host trees they inhabit, since their introduction (invasion) into the United… read more here.

Pre‐ and post‐association barriers to host switching in sympatric mutualists
Sign Up to like & getrecommendations! Published in 2022 at "Journal of Evolutionary Biology"
DOI: 10.1111/jeb.14028
Abstract: Coevolution between mutualists can lead to reciprocal specialization, potentially causing barriers to host switching. Here, we conducted assays to identify pre‐ and post‐association barriers to host switching by endosymbiotic bacteria, both within and between two… read more here.

DOI: 10.1645/23-52
Abstract: ABSTRACT Dicyemids (phylum Dicyemida) are the most common and most characteristic endosymbionts in the renal sacs of benthic cephalopod molluscs: octopuses and cuttlefishes. Typically, 2 or 3 dicyemid species are found in a single specimen… read more here.
