This study focusses on queen excluders, a common hive addition in contemporary beekeeping. Its impacts are controversially discussed but have not been studied scientifically yet. Within a 4-year participatory on-farm experiment, we assessed the effects on colony dynamics in 64 hives in 8 apiaries during one season in Germany using the Liebefeld estimation method. We found no significant deviation for parameters of colony dynamics between hives managed with and without queen excluders. A qualitative decision-making tool (Pugh decision matrix) facilitated concept selection only for specific beekeepers.

Zukünftig werden sie einen Großteil des Energiebedarfs decken – auch in den Sektoren Wärme und Verkehr. Studien zeigen: Für Klimaneutralität 2045 muss die Ausbaugeschwindigkeit auf das Drei- bis Vierfache der letzten Jahre erhöht werden. Komplexe und langwierige Planungs- und Genehmigungsverfahren, zu wenig ausgewiesene Flächen und eine unzureichende Bürgerbeteiligung hemmen jedoch den Ausbau. Das Impulspapier „Vorschläge für einen klimagerechten Ausbau der Photovoltaik und Windenergie“ einer interdisziplinären Arbeitsgruppe des Akademienprojekts Energiesysteme der Zukunft (ESYS) nennt zwölf Handlungsoptionen, um Hemmnisse abzubauen und die Ausbaugeschwindigkeit auf die erforderlichen 15 bis 25 Gigawatt pro Jahr zu beschleunigen.

The results were used to determine parameters for the viscoplastic material model by Chaboche and a damage model by Gurson-Tvergaard-Needleman. The temperature was monitored during the experiments and the self-heating effect was observed. By including this effect, a higher accuracy could be achieved with the results of mechanical experiments.
