Effects of light, nutrients, and grazing on periphyton communities in streams

Creator:

Gregory, Stanley Vincent

Abstract:

Relative effects of light, nutrients, and grazing on primary production were investigated in streams in the Cascade Mountains of Oregon and in laboratory streams. Relative magnitudes of primary production and associated processes were examined for one year in a stream that flowed through a clearcut and an old-growth forest in...

Photosynthetic Energy Allocation Strategies of Thalassiosira pseudonana During Light Limited Growth

Creator:

Fisher, Nerissa L.

Abstract:

Photosynthetic energy allocation strategies were investigated in the marine diatom, Thalassiosira pseudonana, grown under a wide range of light limitation. Steady-state, continuous cultures were established at three light-limited growth rates. Simultaneous measurements of photosynthetic activity were made that targeted different points in photosynthetic energy flow from gross to net photosynthesis....
