Preliminary assessment of cavity-nesting Hymenopterans in a low-intensity agricultural landscape in Transylvania. [PDF]

open access: yesEcol Evol, 2021
Nowadays, most regions of the European Union face an increasing agricultural intensification and urbanization, which partially caused a dramatic decline of insect diversity in the last few decades. However, even in the European Union, there are still a few regions and areas remaining, which are not under such a strong human influence and still harbor a

Müllerian mimicry among bees and wasps: a review of current knowledge and future avenues of research

open access: yesBiological Reviews, Volume 98, Issue 4, Page 1310-1328, August 2023., 2023
ABSTRACT Many bees and stinging wasps, or aculeates, exhibit striking colour patterns or conspicuous coloration, such as black and yellow stripes. Such coloration is often interpreted as an aposematic signal advertising aculeate defences: the venomous sting.

Reproductive aspects and pollination biology in endoparasitic Pilostyles thurberi (Apodanthaceae)

open access: yesPlant Species Biology, Volume 38, Issue 2, Page 40-53, March 2023., 2023
We studied pollination and reproductive strategies of the endoparasitic plant Pilostyles thurberi. The reproductive strategy, floral rewards, pollination system, and variation of their sexual flower arrangement were recorded. This endoparasite presents differences in reproductive success between different sites. Abstract Biotic pollination is typically
