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…

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.
