Research

My research focuses on pollinator responses to changes in landscape structure, exposures to agrochemicals and pressures from (invasive) biotic factors, and the subsequent implications for biological conservation and ecosystem services. For this I generally combine the use of lab experiments, field monitoring and modelling techniques, and I have growing interest in inclusive socio-ecological approaches. My work is oriented towards applied perspectives including the development of decision-support tools for informing environmental policies and stakeholders.

Evolution and Ecology

Our research aims to understand the impact of global changes (anthropogenic and climatic) on insect diversity, abundance and ecology in the context of food security and public health. We are working on insect models with positive impacts on human well-being, such as pollinating insects, edible insects and natural enemies of insect pests, as well as negative impacts such as crop pests and vectors of mammalian parasites. The objectives are to identify the mechanisms underlying the responses of these insects to biotic and abiotic pressures, and to predict the impacts and feedbacks of global change from a management and conservation perspective. The main study sites are located in continental Europe, sub-Saharan Africa and Latin America.

Our locations and partnerships:

implantations

Four main research areas are developed within our pole:

  1. Ecology of insects with production or conservation concerns: changes in land use and climate change can affect the abundance, richness and diversity of insect populations with production or conservation concerns. In this context, we study the ecology of edible insects, the ecology of bees through experimental and empirical approaches as well as the impact of exotic pests on native insect populations, including parasitoids, and on native prey populations (Asian hornet – honey bee interaction).
  2. Adaptation of insects to anthropogenic environments: certain anthropogenic actions lead to the reduction of natural habitats and the invasion of species that can affect agriculture and human health. In particular, we are studying host adaptation in parasitoids used in biological control, the evolution of diet adaptation in predators such as Coccinellidae, and the domiciliation processes of insect vectors of diseases.
  3. Modelling the response of insects to global changes: in a context of global change, it is difficult to have models for predicting the individual and population response of insects. To address this, we model insect phenology (e.g. crop pests) and the spatio-temporal dispersal of insect populations based on experimental or participatory data on climate, landscape and cropping practices. We also use modelling in combination with field data as a decision support tool for environmental management and for the analysis of complex scenarios to be tested in the field such as the combination of multiple stresses.
  4. Functional role of insects in agroecosystems: through their ecological functions, insects determine the dynamic balance of ecosystems. These services and dis-services are key to food security and human health. We study their resilience by jointly analysing the pollination services provided by insects and the dis-services related to pests in agricultural and anthropised systems.

Projet européen SafeAgroBee

The european project SafeAgroBee, founded by the research program H2020 PRIMA from European Union, and in which Fabrice Requier (Pôle Ecologie) is partner, just began. The project aims to preserve the resilience of agroecosystems in the climatic change thanks to an efficient pollinisation and sustainable bee-keeping.

BeeConnected, an european project launched

The european project BeeConnected, which has received funding from the H2020 research and innovation programme from EU, and for which Fabrice Requier (Pôle Ecologie) is the coordinator, just started. In EGCE, 3 scientists are part of this project : Lionel Garnery , François Rebaudo and Etienne Minaud. Moreover, 2 scientists from Würzburg University and 3 greek scientists from Hellenic Agricultural Organization- Demeter are part of the project.

Linking research and beekeeping, the project intends to investigate, develop and test new digital solutions based on data collection to deliver early-warning indicators of honey bee colony mortality and decision-support tools to help beekeepers limiting colony losses and related economic deficits.
