Do floral and ecogeographic isolation allow the co-occurrence of two ecotypes of Anacamptis papilionacea (Orchidaceae)? [PDF]

open access: yesEcol Evol, 2021
Without geographic isolation, gene flow usually homogenizes the allopatrically generated phenotypic and ecological divergences, unless other forms of reproductive isolation keep them separated. Here, we investigated two orchid ecotypes with marked phenotypic floral divergence that coexist in contact zones.

Metabarcoding of trap nests reveals differential impact of urbanization on cavity‐nesting bee and wasp communities

open access: yesMolecular Ecology, Volume 32, Issue 23, Page 6449-6460, December 2023., 2023
Abstract Urbanization is affecting arthropod communities worldwide, for example by changing the availability of food resources. However, the strength and direction of a community's response is species‐specific and depends on species' trophic level. Here, we investigated interacting species at different trophic levels in nests of cavity‐nesting bees and
