Toll-like Receptors (TLR) play a central role in recognition and host frontline defence against a wide range of pathogens. A number of recent studies have shown that TLR genes (Tlrs) often exhibit large polymorphism in natural populations. Yet, there is little knowledge on how this polymorphism is maintained and how it influences disease susceptibility in the wild. In previous work, we showed that some Tlrs exhibit similarly high levels of genetic diversity as genes of...

We conducted annual point counts of birds between 2013 and 2018 at 297 plots across habitats and elevations (2,416-4,303 m) in Volcanoes National Park, Rwanda. These data were subsequently used to determine elevational and habitat preferences via indicator analyses, and to model abundance distributions as a function of temperature, precipitation, habitat availability, and congeneric competition. Of 35 focal species, we found 20 species to be particularly associated with narrow elevational range (<300 m) and 24...
