Description of the thesis topic
Determining the factors responsible for the spatial and temporal distribution of species requires the study of various processes, including interactions between species and their environments, the composition of biotic communities and environmental conditions. The aim of the proposed project is to assess the role and importance of chemical defences in a tribe of neotropical butterflies (Ithomiini) demonstrating remarkable diversification and adaptation to a multitude of microhabitats and hostplants. The thesis student will explore the role of phylogeny, habitat, environmental conditions, predators and the use of resources on the chemical diversity of anti-predator defenses and on the warning signal to explain ecological adaptation and species diversification.
The thesis project will be carried out in the EEBA team (Ecology and Evolution of Biodiversity in the Amazon), as a part of an ANR JCJC, within the LEEISA in Cayenne.
Constraints and risks
Risks inherent in field and laboratory work.
Many short and long-term missions are to be expected in Peru and French Guyane, in sometimes difficult conditions (e.g. heavy rain, mosquitoes, intense heat).
The thesis will be attached to the doctoral school of the University of Guyane.
Candidates are expected to have a MSc degree (Master 2 in France) in the biological sciences. Written applications, including a cover letter, a complete CV, academic transcripts, and the name and contact of at least two referees, must be submitted online on the CNRS website. Please do not hesitate to contact me for more details (firstname.lastname@example.org).
The candidate will also have the following skills or attributes:
-a working knowledge of Spanish and English
-a strong interest for fieldwork (past experience in the tropics is preferable)
-basic knowledge of sampling and identification of arthropods and plants (e.g. inventories, herbarium specimens)
-knowledge of ecosystem and habitat mapping and experience in habitat modeling
-have past experience in experimental biology
-a driving licence is imperative
-possess scientific rigor, autonomy, strong motivation, seriousness and diligence
-have basic knowledge of first aid
-knowledge of French Guiana is desirable
