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

The role of wild bees and cavity-nesting wasps as ecological indicators of the last traditionally managed meadows in Eastern Europe. [PDF]
Ecol EvolThe role of wild bees and cavity‐nesting Hymenopteran species as indicators was examined, along the unique combination of high nature value and traditional land use habitats. The different taxonomic groups of wild bees and cavity‐nesting Hymenopterans showed differences in their habitat affinities.

Molecular 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

Great Lakes Entomologist, 2017 The chalcid wasp Leucospis affinis has been known to parasitize only megachilid bees. Its rare occurrence as a parasite of the eumenid wasp Ancistrocerus anti/ope indicates that eumenid wasps may be a large resource this chalcid is not exploiting ...

Psyche: A Journal of Entomology, Volume 2018, Issue 1, 2018., 2018 Ectatomma tuberculatum has one of the most toxic venoms known among ants but there is no detailed study on its characteristics. In light of this, knowing the venom’s chemical composition is of paramount importance in order to obtain information about the mechanisms of its components.
