Aquatic connectivity

  • We evaluate the effects of culverts on biodiversity

    Small barriers in aquatic ecosystems can strongly affect the biodiversity and many ecosystem functions downstream of the barriers

  • Impacts of barriers in streams on aquatic-terrestrial exchanges

    Barriers to movement (water, organisms and org. inorg. matters) can affect aquatic ecosystems’ biodiversity and functions but can also affect terrestrial biodiversity and functions.

  • We also worked in marine environments to study functional connectivity and partial barrier to movement

    For marine organisms, barriers (or partial barriers) to movement can be large sand patches or conspecifics density. Functional connectivity is way more complex than structural connectivity…

Projects in progress …

  • Examing the effects of culverts on biodiversity, productivity and ecosystem services

    Baptiste Nelaton, PhD project

  • Evaluate the dependency of terrestrial habitats to emergent aquatic insects near culverts

    Matteo Babinski, MSc project

  • Using microcosms and protists to test the impacts of barriers to movement on meta-communities

    Sarah Bertrand, MSc project

… Projects finished

  • Evaluate functional connectivity in a coral reef fish

    Partial barrier to movement can impact meta-population dynamics. With a translocation experiment, we examined how sand patch (predation risk) and conspecifics impact damselfish movement.
