Landscape influence on pollinator population genetic connectivity

open access: yesInsect Conservation and Diversity, Volume 18, Issue 3, Page 285-302, May 2025.
We analysed 113 studies from 59 countries, covering 96 bee and 21 hoverfly species, to review the evidence of environmental and landscape effects on the population genetic connectivity in pollinators. Environmental conditions (precipitation and temperature), topography (elevation and sea), and land use (agriculture, deforestation, urbanisation) were ...

First records of four orchid bee species (Hymenoptera, Apidae: Euglossini) in Ecuador [PDF]

open access: yesJournal of Insect Biodiversity and Systematics
Orchid bees (Hymenoptera, Apidae, Euglossini) play a vital role as key pollinators in the Neotropical forests. Their preference for forested areas makes these bees more susceptible to environmental changes, particularly in areas under severe human impact,

Non‐floral scent sources of orchid bees: Observations and significance

open access: yesBiotropica, Volume 57, Issue 1, January 2025.
We observed male euglossines collecting scent at 21 different non‐floral sources in Central and South America, strengthening the view that these sources play a central role in euglossine perfume biology. A Protium tree provided over 50% of the perfumes for Eufriesea corusca and was repeatedly revisited.

Regioselektive Oxidative Phenolkupplung durch eine Unspezifische Peroxygenase aus Ständerpilzen

open access: yesAngewandte Chemie, Volume 136, Issue 42, October 14, 2024.
Die Biosynthese von Phlegmacin im Ständerpilz Cortinarius odorifer zeigt, dass CoUPO1, eine unspezifische Peroxygenase, den Dimerisierungsschritt durch regio‐ und stereoselektive oxidative Phenolkupplung katalysiert. Diese Studie zeigt, dass Ständerpilze die biosynthetische Arylkupplung unabhängig von anderen Organismengruppen entwickelt haben ...
