The role of facilitation and mutualisms in structuring marine communities


Clams in soft-sediment provide a hard surface for algae.

A large focus for our Lab is understanding how positive interactions promote biodiversity and vital ecosystem functions, and how environmental stress affects these processes. We’re ultimately interested in how we can use positive species interactions to build resilience into coastal ecosystems as they become more stressed.

Research by us and colleagues is providing new insights into how habitat-formers promote other habitat-formers via facilitation cascades and how these cascades can be utilised in the development of conservation and management practices for biodiversity.
