Abstract Background Evolutionary divergence and genetic variation are often linked to differences in microbial community structure diversity. While environmental factors diet heavily influence gut communities, host species contributions harder quantify. Closely related living sympatry provide a unique opportunity investigate without the confounding effects of habitat dietary variation. We therefore compared contrasted microbiota three sympatric plover species: widespread Kittlitz’s white-fronted plovers ( Anarhynchus pecuarius A. marginatus ) endemic vulnerable Madagascar thoracicus ). Results found no significant beta diversity (composition) species. However, exhibited higher intraspecific compositional similarity (i.e. lower pairwise distances) than other two species; this pattern was especially pronounced among juveniles. By contrast, alpha varied significantly species, being highest , intermediate lowest . This again stronger Geographical distance did not affect composition microbiota, but relatedness did. Conclusion patterns across lack suggests that likely exert strong on plovers. may be enhanced by their precocial, ground-dwelling nature, which could facilitate horizontal transmission microbes from environment. hypothesise primarily reflects ecological pool is subsequently modified host-specific including genetics. The reduced hinder its ability adapt changes, highlighting need for increased conservation efforts

ABSTRACT Gut microbiota regulate multiple aspects of host health, including metabolism and the development immune system. However, we still know relatively little about how gut influences responses to parasitism in wild organisms, particularly whether host‐microbiota interactions contribute variation across species. The goal this study was determine role shaping birds respond nest parasites investigate relationship varies between Both eastern bluebirds ( Sialia sialis ) tree swallows Tachycineta bicolor are parasitized by blow flies Protocalliphora sialia ), for which larval feed on nestlings' blood. We experimentally manipulated nestling dosing nestlings with an oral antibiotic or sterile water as a control. then quantified physiology (haemoglobin, glucose, parasite‐specific IgY antibody levels), body morphometrics, survival until fledging, well fly abundance size. An experimental disruption increased parasite swallows, but decreased bluebirds, suggests that has opposing effects resistance Furthermore, treatment delayed had variable morphometrics two Together, these results suggest differences can influence host–parasite interactions.
