Uncovering the genetic basis of adaptation hinges on the ability to detect loci under selection. However, population genomics outlier approaches to detect selected loci may be inappropriate for clinal populations or those with unclear population structure because they require that individuals be clustered into populations. An alternate approach, landscape genomics, uses individual-based approac...

Gyrodromella represents a subgenus of the osmiine bee genus Chelostoma (Megachilidae) containing eight species, which are confined to the Palaearctic region. Analysis of female pollen loads, field observations and literature data suggest that all C. (Gyrodromella) species are oligolectic harvesting pollen exclusively on flowers of Campanula and possibly also closely related Campanulaceae genera...
