2022 - 2024 FarmerBeeWild: Pollinator-friendly agricultural landscapes

Funding: Federal Ministry of Food and Agriculture / Bundesministeriums für Ernährung und Landwirtschaft (BMEL)

Projektträger: Federal Office for Agriculture and Food / Bundesantalt für Landwirtschaft und Ernährung (BLE)

Summary

Various agricultural policy instruments (e.g. greening) and compensation payments for environmentally-friendly management (e.g. KULAP) aim to counteract the decline in insects. However, their effectiveness in promoting pollinator diversity has hardly been studied and especially data on landscape level and on interactions between measures are lacking. The aim of this project is to (1) assess the pollinator situation of Bavaria's agricultural landscapes, (2) evaluate the success of current measures in promoting wild bees and pollination services, and (3) make recommendations on which combinations of practicable measures can be used to make agricultural landscapes more bee-friendly in the future.

Species groups: bees and other pollinators

Study regions: Bavaria (Germany)

Habitat: agricultural landscapes

2021 - 2025 SAFEGUARD: Safeguarding European wild pollinators

Funding: European Union's Horizon 2020 research and innovation programme
Webpage: https://www.safeguard.biozentrum.uni-wuerzburg.de

Summary

Safeguard aims to substantially contribute to reversing the loss of wild pollinators across Europe through increasing our understanding of the direct and indirect drivers of pollinator declines, environmental, economic and societal impacts and delivering an integrated assessment framework as basis for a portfolio of effective policy and practice solutions. Our goal is to inspire the development of management and policy guidelines for the public and private sectors to safeguard wild pollinators and the benefits they provide. Field studies on bees, hoverflies and butterflies will be conducted with a joint study design in 12 European countries.

Species groups: bees, hoverflies and butterflies

Study regions: Würzburg and Bayreuth (Germany) and 11 other European countries

Habitat: calcareous grasslands, agricultural and urban landscapes

2019 - 2027 Dorfbienen: Wildbienen in Dörfern

Förderer: Bayerisches Landesamt für Umwelt, Biodiversitätszentrum Rhön
Homepage: www.dorfbienen.biozentrum.uni-wuerzburg.de

Zusammenfassung:
Dörfer sind ein wichtiger Teil unserer Kulturlandschaft. Sie dienen als Wohnort, der Erholung und der Produktion von Obst und Gemüse, und bieten wertvolle Lebensräume für Insekten und Wirbeltiere. Für die ca. 550 Wildbienenarten in Deutschland liefern artenreiche Gärten, Obstbäume, Wildgehölze und strukturreiche Grünflächen ein vielfältiges Nahrungsangebot. Alte Holzscheunen, Obstbäume mit Totholz, Trockenmauern und offene Bodenflächen in Dörfern werden von vielen Wildbienen als Nistplätze genutzt. Mehr als die Hälfte der Wildbienenarten in Bayern sind durch das Verschwinden oder eine verminderte Qualität ihrer Lebensräume gefährdet. Zunehmender Nutzungsdruck, der Verlust von Kleinstrukturen und Flächenversiegelung, führen oft zu einer ökologischen Verarmung der Kulturlandschaft und damit dem Rückgang der Artenvielfalt im ländlichen Raum. Private Gärten und öffentliche Grünflächen sollen möglichst pflegeleicht und "ordentlich" sein, Unkräuter und Schädlinge werden ohne ökonomischen Zwang mit Pestiziden bekämpft und Flächen werden zur Minimierung des Pflegeaufwandes versiegelt. So sind in vielen Dörfern in den letzten Jahrzehnten vielfältige Lebensräume verloren gegangen. Dörfer besitzen ein großes Potential für die Förderung von Wildbienen und anderen Insekten. Im Dorfbienenprojekt untersuchen wir welchen Wert verschiedene Lebensräume in Dörfern für die Erhaltung der Artenvielfalt besitzen und wie die Vernetzung mit der umgebenden Landschaft die Vielfalt von Wildbienen beeinflusst. Ziel ist, gemeinsam mit den Gemeinden blütenreiche und vielfältige Lebensräume zu fördern und zum Schutz einheimischer Wildbienen und anderer Insekten beizutragen.
Projektziele: (1) Erfassung der Artenvielfalt von Wildbienen in Dörfern; (2) Erfassung der Blütenpflanzen und Nistplatzstrukturen; (3) Bewertung der Landschaftsvernetzung; (4) Entwicklung von Managementmaßnahmen in Dörfern; (5) Fördern des Wissenstransfers in die Gesellschaft

Artengruppen: Wildbienen und andere Bestäuber

Untersuchungsgebiete: Rhön und Mainfranken

Habitat: Dörfer und umgebende Agrarlandschaft

Methods: Feldaufnahmen und Bestäubungsexperimente, Landschaftsökologie

2015 - 2018     Enhancing biodiversity-based ecosystem services to crops through optimized densities of green infrastructure in agricultural landscapes ECODEAL (Biodiversa/BMBF)

Project summary:
Ecological intensification relies on ecosystem services to substitute external inputs in agriculture and has been proposed as a way to achieve high yielding, stable and sustainable crop production, while allowing to reach other societal targets such as nature conservation or human health. Pollination and natural pest control are key ecosystem services that can reduce pesticide use and increase crop yield quantity and quality. Organisms delivering these services depend to a large extent on non-crop habitats, or "green infrastructure" in the landscape, as cropland is not well suited as a habitat all year round. The project aims to answer the following questions: How much green infrastructure do we need to maintain stable communities of ecosystem service providers, and a high flow and stability of the services to the crop? Which type or combination of green infrastructure, old or young flower areas, arable fallows, seminatural grasslands, optimizes farmland biodiversity and ecosystem services? Since establishing non-crop habitat comes at a cost, which densities of green infrastructure will enhance crop yield and populations of service (or conservation) relevant species while providing net increases in crop productivity as well as net economic benefits to the farmer? ECODEAL will answer these questions.

2013 - 2017  Collaborative Research Center "Insect timing" (Sonderforschungsbereich SFB 1047)
Within the Collaborative Research Center "Insect timing", my group focuses on timing in plant-pollinator interactions. A mismatch in timing of mutualistic interaction partners might result in the disruption of such interaction, and potentially endangers the fitness of the partners. So far, it has been rarely studied  how changes in temperature, e.g. caused by anthropogenic climate change, shift the timing and fitness of interacting species. The central questions of this project are:

- How does ambient temperature affect the timing of the larval development and the emergence of pollinators?

- Does temperature synchronize the activity period of pollinators to the flowering period of their food plants, and can temporal mismatches be counteracted by bet-hedging strategies or by phenological plasticity, which might allow the re-adjustment of activity times in accordance to the timing of the partner?

- Can negative effects of mismatches be buffered by other (previously unimportant) species of the same functional group?
