How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more

The City Nature Challenge (CNC) from iNaturalist is a competitive event between cities and carried out since 2016 - initially only in the USA - with the aim of collecting as much data as possible about the occurrence of species using georeferenced, digital photos or recordings. The gained data should create a better basis for biodiversity studies a...

Vibratory signals play a major role in the organization of honeybee colonies. Due to the seemingly chaotic nature of the mechano-acoustic landscape within the hive, it is difficult to understand the exact meaning of specific substrate-borne signals. Artificially generated vibrational substrate stimuli not only allow precise frequency and amplitude...

The wilderness area Dürrenstein-a habitat for feral honey bee colonies? This is an initial study on wild (or feral) honey bee colonies (Apis mellif-era) in the Dürrenstein wilderness area in Austria, using the method of "Beelining", as described by T.D. Seeley. The wilderness area is free of managed bee colonies and surrounding apiaries are known....

Molecular genetic methods are increasingly used to supplement or substitute classical morphology-based species identification. Here, we employ a COI mini-barcode coupled high-resolution melting analysis to quickly, cost-efficiently and reliably determine larvae of two closely related Cychramus (Coleoptera, Nitidulidae) species. Euclidean distance c...

We conducted a citizen science survey on overwinter honey bee colony losses in Austria. A total of 1534 beekeepers with 33,651 colonies reported valid loss rates. The total winter loss rate for Austria was 15.2% (95% confidence interval: 14.4–16.1%). Young queens showed a positive effect on colony survival and queen-related losses. Observed queen p...
