Research interests

I have a broad interest in the functional ecology of animal and plant communities in both natural and cultivated ecosystems affected by global changes. Over the last decade, I have been conducting research programs in a wide variety of ecosystems - from the amazon rainforest to the high altitude agricultural landscapes to glacier fore fields- along the altitudinal gradients of the tropical Andes (mainly in Ecuador and Bolivia). I am interested in integrative and trans-disciplinary studies, in particular in modelling approaches coupling physical, biological and social systems. Most of my research is conducted in the framework of the Joint International Laboratory BIO_INCA that I have created in 2018 in collaboration with Ecuadorian and Colombian partners (see below). I also have a strong interest in science communication through a wide array of medias (books, photography exhibitions, webdocs, movies, see below).

International Joint laboratory (LMI) - www.bioinca.org @bio_inca

The main objective of the LMI BIO-INCA is to promote the emergence of an operational research platform, specialized in the integrative study (from genomes to socio ecosystems) of natural and cultivated phytosystems of the Andean region (highlands and foothills). The research engendered by this structure is aimed at the interface between the basic and applied sciences, with the objective of proposing concrete solutions to the adaptive management of natural and cultivated phytosystems. This research is organized into four main scientific objectives: 1) the characterization of cultivated and wild biodiversity, 2) the study of biological interactions, 3) the study of ecosystem services and nature-based solutions, and 4) the development of innovative tools and training programs.

Thèmes de recherche

Recherches en zoologie du sol, centrées sur les macro-invertébrés saprophages qui se nourrissent de résidus végétaux, tels que les macroarthropodes (Diplopodes, Isopodes) et les vers de terre (Oligochètes). Mes travaux sur la biologie et l’écologie de ces animaux portent principalement sur quatre grands thèmes :

1. La composition et la structure des peuplements de macro-invertébrés saprophages
Mots-clés : abondance, biomasse, diversité, structure fonctionnelle

2. Le rôle des macroarthropodes saprophages dans la décomposition des litières
Mots-clés : choix alimentaire, consommation, assimilation, bilan annuel

3. Les réponses des macroarthropodes saprophages aux changements globaux
Mots-clés : changement climatique, qualité des litières, biodiversité

4. Le cycle de vie des populations de Diplopodes en conditions naturelles
Mots-clés : vitesse de développement, reproduction, adaptations saisonnières

I am interested in how changes in biodiversity and environmental conditions (atmospheric carbon dioxide, temperature, precipitation) affect plant-soil interactions, with a particular focus on plant litter and decomposer organisms. The main research goal is a mechanistic understanding of the drivers of biogeochemical cycles using experimental approaches in the field (alpine, temperate, Mediterranean and tropical forest ecosystems) and the laboratory.
