Lay Summary (German)

Lead
Wir untersuchen, welche natürlichen Ressourcen nützliche Insekten benötigen (Hummeln, Wildbienen, Marienkäfer, Schwebfliegen) um ihre Funktion in den Kulturen (Bestäubung, Prädation) wahrnehmen zu können. Dafür werden die Ressourcen bestimmt (Pollenanalyse, Analyse Darminhalte) und anschliessend die Landschaften aus dem Blickwinkel der Insekten kartiert („Resource maps“). Darauf aufbauend wird versucht, das Ressourcenangebot gezielt mit Blühstreifen zu verbessern.
Lay summary
 Im ersten Jahr des Projektes werden wir die von ausgewählten Hummeln, Solitärbienenarten und räuberischen Insekten benötigten Ressourcen identifizieren. Durch die Analyse der Pollen, welche im Feld gefangene Bestäuber und Nutzinsekten auf sich tragen, können die Pflanzenarten identifiziert werden, auf denen sie sich aufgehalten haben. Mit molekularen Methoden werden wir die Darminhalte von Marienkäfern analysieren und so die Beute (Blattlausarten) bestimmen können, welche sie verzehrt haben.
Im zweiten Jahr werden wir diese Ressourcen in der Landschaft rund um ausgesuchte landwirtschaftliche Kulturen kartieren. Dazu verwenden wir eine Kombination von Luftbildern und Feldarbeit. Unsere Testgebieten werden einen Landschaftsgradienten aufweisen: (i) Landschaften, die im Frühjahr reich an Ressourcen sind, damit Bestäuber und Nutzinsekten früh mit dem Aufbau ihrer Populationen beginnen; (ii) Landschaften, in denen diese Ressourcen zur gleichen Zeit wie in der Kultur vorhanden sind und in der Kultur ein Bedarf an Bestäubung oder Schädlingskontrolle besteht und (iii) Landschaften ohne alternative Ressourcen. Wir werden das Vorkommen von Bestäubern und Nutzinsekten und die Ökosystemdienstleistungen, welche sie erbringen, messen.
Im dritten Jahr werden wir versuchen, die Verfügbarkeit von Ressourcen durch die Ansaat von Blumenstreifen neben den Nutzpflanzen zu erhöhen. Wir werden die Auswirkungen dieser Blumenstreifen auf Bestäuber, Nutzinsekten und auf ihre Wirksamkeit untersuchen.
Von den Ergebnissen werden wir Empfehlungen für ein verbessertes Management und Agrarumweltmaßnahmen zur Förderung der funktionellen Biodiversität und Ökosystemleistungen in der Agrarlandschaft ableiten.

Abstract

Biodiversity and ecosystem functioning are threatened by the loss and fragmentation of habitats providing vital resources for organisms. In agricultural landscapes, the loss of biodiversity may disrupt important ecosystem services (ES) such as crop pollination and natural pest control. Existing studies of fragmentation effects on func-tional biodiversity mostly characterize landscapes according to broad habitat categories such as “non-crop” or “semi-natural habitat”. The aim of the proposed project is to improve our mechanistic understanding of the drivers and consequences of effective functional fragmentation as a prerequisite for robust predictions of ES. We will examine (i) the resource requirements of key insect pollinators and natural enemies of agricultural pests, (ii) effects of the spatio-temporal distribution of these resources on pollinators and natural pest enemy communities in agricultural landscapes plus the functional consequences on ES delivery to crops, and (iii) their interactions with resources at the community level (ecological networks). Food resource requirements will be quantified using (i) pollen present on field-captured solitary bees, bumblebees, ladybirds and lacewings (aphid predators) and (ii) consumed prey (aphid) species through gut content analysis of predators (ladybirds) using next generation sequencing. From this, we will develop functional habitat maps for 48 landscapes that consider the spatial distribution of resources and their temporal availability relative to focal crops. Predictions about the effects of temporally preceding or synchronous alternative resources will be tested in a field survey of focal insect species in these 48 landscapes, while also quantifying the levels of ES delivery in focal crop fields. In addition, we will test fitness effects of spatio-temporal resource availability on pollinators by monitoring bumblebee colonies in the different landscapes in Germany. Finally, we will experimentally enhance food resource availability for pollinators and aphidophagous insects and manipulate the timing of available resources using specifically designed flower strips. The fundamental ecological knowledge on spatio-temporal resource use affecting the structure and dynamics of plant-pollinator and predator-prey communities, their interactions and functional consequences gained by the proposed research, will help to improve landscape management and agri-environment schemes aimed at promoting functional biodiversity and ecosystem services in agricultural landscapes.
