The lab studies how forests influence stream environments and the organisms that live in them.

AboutAbout the lab
Exploring the links between forests and streams
Assistant Professor Mitsuru Ohira studies how forests influence stream environments and the assembly of stream biological communities.
The lab examines how disturbance, succession, and management of forests on hillslopes, in riparian zones, and across watersheds change the supply of water, sediment, and organic matter to streams, and how organisms respond.
Alongside how a forest's influence spreads downstream through the stream network, the lab also considers watershed management.
Key terms
- Riparian zone
- The land right next to a stream flowing through mountain valleys
- Succession
- The gradual change over the years in the composition and structure of a forest's plants after an event such as logging or a wildfire
- Disturbance
- An event, such as a typhoon or logging, that greatly changes the state of a forest
ResearchResearch themes
Specializing in stream ecology, the lab studies how forests contribute to the formation and maintenance of stream ecosystems. It focuses on organisms such as aquatic insects and fish.
