The study found that the relationship between Syringophilidae mites and columbiform birds forms a complex ecological network with high specialization. Mites parasitize on the calamus of pigeons and doves, with different levels of interaction between different hosts.
Simple Summary Mites of the family Syringophilidae (Acariformes: Cheyletoidea)-also called quill mites-are permanent and highly specialized ectoparasites of birds living inside the calamus of the various types of the feathers. In the present paper, we conducted a study focused on prevalence, host specificity, networks, and phylogeny of the syringophilid mites parasitizing on pigeon and doves (Columbiformes). We postulate that the Syringophilidae mites and Columbiformes bird system represent a model which can be used in a broader study of the relationship between hosts and parasites. The quill mites belonging to the family Syringophilidae (Acari: Prostigmata: Cheyletoidea) are obligate ectoparasites of birds. They inhabit different types of the quills, where they spend their whole life cycle. In this paper, we conducted a global study of syringophilid mites associated with columbiform birds. We examined 772 pigeon and dove individuals belonging to 112 species (35% world fauna) from all zoogeographical regions (except Madagascan) where Columbiformes occur. We measured the prevalence (IP) and the confidence interval (CI) for all infested host species. IP ranges between 4.2 and 66.7 (CI 0.2-100). We applied a bipartite analysis to determine host-parasite interaction, network indices, and host specificity on species and whole network levels. The Syringophilidae-Columbiformes network was composed of 25 mite species and 65 host species. The bipartite network was characterized by a high network level specialization H2 ' = 0.93, high nestedness N = 0.908, connectance C = 0.90, and high modularity Q = 0.83, with 20 modules. Moreover, we reconstructed the phylogeny of the quill mites associated with columbiform birds on the generic level. Analysis shows two distinct clades: Meitingsunes + Psittaciphilus, and Peristerophila + Terratosyringophilus.
