Interactions Biotiques

Rumsais BLATRIX

Chargé de recherche au CNRS

 

Mon activité de recherche porte sur les aspects écologiques et évolutifs des interactions entre espèces. Les deux thèmes principaux que j'étudie sont les interactions symbiotiques entre plantes, fourmis et champignons, et les interactions entre ingénieurs d'écosystèmes dans la structuration du paysage.

 

My research activity is focused on the ecological and evolutionary aspects of inter-specific interactions. My two main study topics are the symbiotic interactions among plants, ants and fungi, and the interaction among ecosystem engineers in landscape patterns.

Activités de recherche

Axe 1 : Ecologie et évolution des symbioses plantes-fourmis-champignons

Dans les forêts tropicales, certaines plantes présentent des structures naturellement creuses (feuilles, tiges, pétioles ...) dans lesquelles vivent des fourmis. La plante fournit le gîte et le couvert (sous forme de nectar extrafloral par exemple). En contrepartie, les fourmis protègent la plante des herbivores et contribuent à l'approvisionnement de la plante en azote. Dans les cavités de la plante, les fourmis cultivent des champignons (de l'ordre des Chaetothyriales) qu'elles consomment. A partir de ce modèle d'étude j'aborde plusieurs sujets relatifs à l'écologie et à l'évolution des symbioses:

- Histoire évolutive des associations symbiotiques.

- Génétique des populations des partenaires symbiotiques.

- Spécificité d'association.

- Flux de nutriments entre les partenaires symbiotiques et stratégies d'approvisionnement.

- Médiation et communication chimique entre les partenaires symbiotiques.

Axe 2 : Organisation spatiale des paysages à motifs répétés

Certaines savanes tropicales sont constellées de buttes en terre (1-20 m de diamètre) régulièrement espacées. Dans la majorité des cas, ces buttes sont soit construites par des invertébrés du sol ("savanes à termites" par exemple), soit construites par l'homme pour permettre l'agriculture sur sols pauvres et régulièrement inondés (champs surélevés). Dans ces mêmes savanes saisonnièrement inondées se trouvent des barrages à poissons en terre. Les champs surélevés et les barrages à poissons en terre sont utilisés actuellement en Afrique, et présents sous forme de vestiges archéologiques pré-colombiens en Amérique du Sud. A partir de ces modèles d'étude j'aborde plusieurs sujets relatifs à l'organisation spatiale des paysages:

- Origine de la régularité spatiale des motifs répétés du paysage.

- Interactions entre les activités de l'Homme, les activités des invertébrés du sol, et leur milieu.

- Rôle des invertébrés du sol dans la conservation des vestiges archéologiques en terre.

Activités annexes

- Interactions tropiques entre acariens dans les élevages de poules pondeuses.

- Interactions entre fourmis et champignons entomopathogènes.

English version:

Axis 1: Ecology and evolution of ant-plant-fungus symbioses

In tropical forests, some plant species have hollow structures (leaves, twigs, petioles ...) in which ants live. The plant provides nesting sites and food (e. g. extra-floral nectar). In return, the ants protect the plant against herbivores and provide it with nitrogen. In plant cavities, the ants grow fungi (of the order Chaetothyriales) for food. I use this study model to address various topics related to the ecology and evolution of symbioses:

- Evolutionary history of symbiotic associations.

- Population genetics of symbiotic partners.

- Partner specificity.

- Nutrient flux among symbiotic partners and nutrient acquisition strategies.

- Chemical mediation and communication between symbiotic partners.

 

Axis 2: Spatial organization of landscapes with repeated patterns.

Some tropical savannahs are dotted with regularly spaced earth mounds (1-20 m in diameter). In most cases, these mounds are either built by soil invertebrates (e.g. termite savannahs), or built by humans to grow crops on poor and regularly flooded soils (raised fields). Earthen fish weirs also occur in these seasonally flooded savannahs. Earthen fish weirs and raised fields are in use today in Africa, and occur in South America as pre-Columbian archaeological vestiges. I use these study models to address various topics related to landscape spatial organization:

- Origin of spatial regularity in repeated patterns of the landscape.

- Interactions between human activities, soil invertebrates activities, and their environment.

- Role of soil invertebrates in the conservation of earthen archaeological vestiges.

 

Side projects

- Taxonomy, biodiversity and ecology of the ants of the Western Palaearctic.

- Trophic interactions among mites in farms of laying hens.

- Interactions between ants and entomopathogenic fungi.
