Research

We work on topic related to the integration of ecological and evolutionary concepts into a spatial perspective. Our work puts interactions central to understanding patterns and dynamics of biodiversity. We study interactions at different levels of biological organisation, from genes to individuals, populations and species. We are particularly interested in understanding how these interactions determine feedbacks between ecological and evolutionary processes, and as such shape the dynamics of populations and species in spatially structured environments. We focus on a diverse spectrum of symbiotic to antagonistic interactions and overall aim to understand how they impact the coexistence of species and strategies at local, regional and even global scales. We study how individual interactions affect the distributions and spread of species, how the emerging species interactions affect dispersal and therefore fluxes of genes, individuals and species between spatially structured population and communities, and how these interactions feedback on ecosystem properties. We have a particular interest in movement ecology & the evolution of dispersal, the distribution and community ecology of arthropods, their associated microbiomes and interactions, biomorphogenic feedbacks and dune development, (citizen) science of urban ecology and evolution, and more recently the eco-evolutionary dynamics of whole genome duplications.

We achieve these goals by integrating theoretical, correlative and experimental approaches, using a wide array of methodological techniques (from molecular techniques to remote sensing) by collaborating with partners from multiple national and international research institutes and universities. Our research, while fundamental by nature, contributes to further developments of nature based solutions (coastal protection), nature management and species (mostly arthropod) conservation.

Major topics

Movement ecology & evolution

Understanding the mechanisms leading to variation in dispersal is of crucial importance to understand how changes in habitat- and resource distribution feedback on higher-level ecological processes and patterns. We use behavioural ecological and field-based approaches with arachnids, insects as model systems to study the ecological and evolutionary drivers of movement and dispersal, and mesocosms approaches to infer its impact on patterns of ecological specialisation and range expansion. We additionally generate solid theory on the eco-evolutionary aspects of dispersal by means of individual based modelling. Current projects focus on the importance of costs and trade-offs on dispersal during range expansion and invasions, condition-dependent dispersal in food webs and the evolution of information use during dispersal.

Spatial selection and life history evolution

With the introduction of the concept of metapopulations the awareness that spatial structure affects demographic and population dynamical processes steadily grew. Such a variation in spatial structure generates typical disequilibrium conditions which are mediated by population extinction and variable demographic dynamics. In contrast to single, unconnected populations, local selection pressures are expected to operate in concert with those acting at the metapopulation level. Given the fact that the vast majority of theory on life history evolution neglects extinction-recolonisation dynamics typical for metapopulations and the complex connection among traits, we combine experimental evolution with modeling to understand complex eco-evolutionary dynamics (also in relation to whole genome duplication within the Methusalem project lead by Prof. Van de Peer) in spatially structured systems. We combine such research with field-based studies focussing on the life history evolution dynamics in function of urbanisation, habitat fragmentation and range expansion.

Community ecology & evolution

The way local communities and ecosystems react to environmental change depends on interaction between local and regional responses at all scales of biological organisation. The spatial configuration of populations and communities is as such an important environmental driver as it determines rates of movement and the strength of local and regional regulatory processes.

We study how the community assembly of plants and animals is influenced by spatial structure and the eco-evolutionary dynamics among individual organisms. Current projects focus on:

  • the structure of arthropod metacommunities within the context of urbanization and habitat fragmentation – we use trait-based and network approaches to understand the underlying processes
  • the relation between above-and belowground parasites and mutualists on the one hand and keystone plant species on the other hand.

The importance of inter- and intraspecific variation in arthropods traits for ecosystem functioning is studied in coastal dunes and urban environments. We rely on citizen science to collect global data on orb web spider traits (SpiderSpotter App) and develop theoretical models to understand the importance of body size and movement (evolution), foodweb and metacommunity functioning. Recent projects focus on the organisation of communities associated with single arthropod species: arthropod nest symbionts in ants and microbial associations in spider mites. The importance of plant genotypes and drought stress for associated arthropod communities, herbivory and eventually plant fitness is studied in the Biodiversa project PlantCline, using woodland strawberries as a model.

Ecological restoration and forecasting

Anthropogenic disturbance and nature management have severe effects on the ecological and evolutionary mechanisms that eventually local diversity and ecosystem functioning. We use these insights to study the impact of climate change on plant-plant, plant-herbivore and plant-arthropod interactions using experimental approaches. We further collaborate in other applied ecological projects that aim to understand and predict the specific impact of connectivity restoration and nature management on the conservation and restoration of arthropod and plant communities. Current projects focus on the ecological restoration of heathlands, chalk and dune grasslands with a special focus on connectivity. We have a specific expertise in coastal dune ecology and develop predictive models to assess the impact of climate change on coastal dune functioning (see interview) and the development of dunes as nature based solutions (presentation and video on creating dunes in front of dikes). Much conservation-oriented research is performed in close collaboration with INBO.
