This is a bibliography of the work of T. L. Jackson, who conducted research at the North Willamette Research and Experiment Center. It is limited to those Extension publications and research reports that addressed the nutrient needs of fresh market and processed vegetables.
Longitudinal patterns of fish and benthic invertebrate distribution and
habitat use were similar in Thomas Creek, Oregon but clarity of these patterns
differed. I studied fish and aquatic invertebrates simultaneously, at multiple
scales, and used multivariate statistical techniques to compare responses to the
same environmental conditions. Both types of organisms...
The complexity of human/riverine systems has led to an increasing focus on land
use patterns and policy. My goal is to understand the dynamics of a coupled human and
natural system. The central question is how people in the community of Scio, Oregon
perceive flooding, water quality, and riparian habitat....
This research seeks to answer the question, "What does it mean for a student to
understand the concept of derivative?" A structured way to describe an individual student's
understanding of derivative is developed and applied to analyzing the evolution of that
understanding for each of nine high school seniors during...

The distribution and geographic range of Greater Sage-Grouse (Centrocercus urophasianus) have been reduced by 56% since European settlement. Although loss and fragmentation of sagebrush (Artemisia spp.) habitats have been cited as the primary causes for the decline of the species, degradation of existing habitat also has been considered an important...
The present day vegetation pattern of the Willamette Valley is a result of a long past of human alteration of the landscape. Beginning with aboriginal burning of the grasslands to present day land uses, the vegetation of the valley has been affected by anthropogenic activity. Wet prairie is a vanishing...
