Interference dynamics in mixed red alder/Douglas-fir forests

Creator:

D'Amato, Anthony W.

Abstract:

This study characterized the nature and dynamics of interference in mixed red alder (Alnus rubra Bong.)/Douglas-fir (Pseudotsuga menziesii [Mirb.] Franco) stands in the Pacific Northwest, USA. Long-term spatial and tree measurements from the Cascade Head (CH) and H.J. Andrews (HJA) Experimental Forests in western Oregon and Delezene Creek (DC), Washington...

Effect of solution nitrogen and phosphorus on growth, carbon allocation and nitrogen fixation of red alder seedlings

Creator:

Lipp, Cynthia C.

Abstract:

The effect of solution nitrogen (N) and phosphorus (P) concentrations on biomass production and N₂ fixation of red alder (Alnus rubra Bong.) seedlings grown in perlite-filled pots in a climate controlled growth room were studied. Nodulated seedlings were subjected to 12 different nutrient solution combinations of nitrogen and phosphorus and...

Germination and first-year survival of red alder seedlings in the central Coast Range of Oregon

Creator:

Haeussler, Sybille

Abstract:

The role of disturbance in seed germination and first-year survival of red alder (Alnus rubra) was studied over two growing seasons at four sites representing a climatic gradient within the central Coast Range of Oregon. Disturbance affected red alder seed germination and seedling establishment by altering the temperature and moisture...
