The Community Ecology and Biogeography Lab at Concordia University in Montreal, Canada, led by Professor Jean-Philippe Lessard, is inviting applications for a PhD position focused on community ecology and biogeography. The research group investigates the ecological and evolutionary determinants of species range limits and dynamics, especially in the context of environmental changes. Possible research topics include the assembly rules of ecological networks such as plant-pollinator, plant-microbial, and host-parasite networks, as well as the role of ants and other soil arthropods in nutrient cycling and carbon storage. This opportunity is ideal for candidates interested in biodiversity, climate change, entomology, and the functioning of ecological communities. The lab offers a collaborative environment for research on pressing ecological questions, with access to resources and expertise in ecology, biogeography, and related fields. Applicants should have a strong background in biology, ecology, or environmental science, and an interest in community ecology and biogeography. Experience with ecological networks, entomology, or soil science is considered an asset. Funding details are not specified in the announcement. Interested candidates are encouraged to visit the provided link for further information and application instructions. The position is based at Concordia University, a leading Canadian institution known for its research in environmental science and biology.
