A stable carbon isotope approach to distinguish climate stress from other imposed stresses in coniferous forests

Creator:

Panek, Jeanne A.

Abstract:

To understand the effect of human-induced stresses on forests, there is a need for a method to separate effects of imposed stress from effects of natural climate stress. I developed an approach to predict forest response to climate stress using as indicators stable carbon isotopes in tree foliage and growth-rings....

Habitat use, spatial ecology, and stable isotope variability of the Pacific harbor seal (Phoca vitulina richardii) along the Oregon coast

Creator:

Steingass, Sheanna M.

Abstract:

Pacific harbor seals (Phoca vitulina richardii) are one of Oregon’s most common coastal predators, numbering between 10,000 and 12,000 individuals (Brown et al. 2005b). They consume more than 149 species or types of marine prey within the Pacific Northwest, which include a large variety of commercially important fisheries species. Despite...
