Research Interests/Duties

Impacts of invasive species, climate change, and disturbance on ecological function of Pacific Island streams, coastal wetlands and mangroves; ecology and community dynamics of fish and invertebrates in streams, coastal wetlands, and mangroves; quantifying ecosystems services of mangrove forests.

  • Climate Change and Native Hawaiian Shrimp

    The life cycle of native Hawaiian shrimp depends heavily on stream flow to carry them out to sea. A warmer, drier climate means less water in the streams, which could jeopardize their viability. In this video, PSW research ecologist Dr. Rich MacKenzie talks about his research on the shrimp and what they tell us about the surrounding ecosystem. [length: 5:13]
