Research interests

My research aims to understand the structure, dynamics and functioning of biological communities: how biodiversity and species interactions affect community structure and stability, and how they affect the functioning of ecosystems. My work sits at the interface of pure and applied ecology, and investigates community ecology questions in the context of theory, fieldwork and experiments.



Structure and dynamics of complex ecological networks
Most research in ecological networks relies on static snapshots of species interactions. Yet, communities are dynamic, species interactions are forged and broken up over the assembly process (or following disturbances), and this likely has effects on the functioning and stability of ecosystems. I am interested in exploring how and why the structural properties of biological communities change, as well as in investigating the dynamics and stability of complex networks of networks (Lurgi et al. In press, Montoya et al. 2015).




Response to perturbations (e.g. habitat loss, climate change, invasions)
Ecological interactions are key to understanding the effects of perturbations on ecological communities. As Janzen (1974) remarked in the so-called ‘empty forest’ hypothesis, in addition to the loss species, habitat loss also leads to the loss of inter-specific interactions. This changes the structure of ecological networks, which in turn affects their stability, functioning and further responses to different or similar on-going perturbations. My work explores what factors confer more resistance to species in face of perturbations, and the effects of climate change, invasions and habitat destruction in complex food webs (Montoya et al. 2008, Montoya et al. 2010, Russo et al. 2014).




Community patterns in space and time
What factors drive the observed patterns in biological communities? How do these patterns change at different spatial and/or temporal scales? What explains this possible variation? My work aims at investigating the relationships between local and landscape scales, the spatial structure of species interaction networks, and the historical drivers of contemporary and ancient ecological networks (Montoya et al. 2007, 2009, Nenzen et al. 2014, Montoya et al. 2015).




Restoration ecology
Given that anthropogenic disturbance of natural habitats has led to large-scale loss of both biodiversity and ecosystem functions, restoration is usually targeted as a powerful solution to revert this trend. The practice of ecological restoration, however, is usually based on local understanding of how particular communities or ecosystems work, without any real reference to a recognized body of theory or generalized framework. Thus, developing a sound theoretical foundation based on current knowledge and concepts from community ecology theory (food web theory, metacommunity theory, biodiversity-ecosystem functioning) will give restoration ecology the opportunity to be able to provide general approaches that can be tried and tested in different systems and places. Moreover, restoration provides important insights into the way that ecological communities are assembled and function (Montoya et al. 2012, Ribeiro et al. 2015).




Agroecology
Agro-ecosystems are characterized by a high human dominance and impacts (pesticides, habitat fragmentation), spatial heterogeneity (mosaics of crops and semi-natural habitats), and frequent temporal changes (annual crops), and thus they represent a prime example of where a better understanding of the spatial dynamics and temporal stability in the provision of ecosystem services (ES) will be most fruitful. One of the agro-ecology paradigms relies on the hypothesis that reducing reliance on agrochemicals (i.e. pesticides, herbicides and fertilizers) will result in increasing biodiversity. The provision of ES that rely on biodiversity, such as pollination and pest control, may help maintaining crop production and compensate the reduction of agrochemicals. Testing this hypothesis needs to understand the relationship between biodiversity and ecosystem functioning, and how spatial and temporal arrangement of the agro-ecosystem modifies this relationship and the magnitude and the stability of ES. This is a joint project (CNRS & INRA), and our objectives are two-fold: (i) to develop a theoretical framework of stability of multiple ES in heterogeneous landscapes, and (ii) to offer new perspectives on landscape management that better take into account the spatiotemporal dynamics of the aforementioned ES, as well as the stability of ES in addition to the magnitude in their provision.
