  Citation × Citation Citation Abstract Copy Title: The seasonal occurrence and distribution of stoneflies (Plecoptera) of a western Oregon stream Author: Kerst, Cary Dean Plecoptera were collected from four sampling stations selected to represent a range of conditions on Oak Creek, a small woodland stream originating in the foothills of the Oregon Coast Range. The elevation of Site I was 700 ft. while the lowest site was located at 225 ft. Monthly benthos samples were taken for one year from a riffle and glide section at each site using a stovepipe sampler (6 in. dia. ) and a standard tropical fish net. Samples were sorted in the laboratory and Plecoptera identified and placed into 1 mm size classes. Emergence of adults was measured for 13 months using a tent-shaped trap (1 m²) at each site. Traps were checked once or twice weekly. Forty-two species of Plecoptera were found in Oak Creek. The number of species is very large when compared with other studies. The stonefly fauna is fairly similar to that reported 35 years ago. Thirty-seven of the 42 species complete emergence during the spring. Temporal separation is marked in the emergence periods of Nemoura and Leuctra. Examples of split emergence periods and early emergence of males were found. Life cycle information is given for a number of species and genera. Using the Shannon-Wiener function, diversity of emerging adults ranks by season as: Spring > Summer > Winter > Fall. The diversity of the sites on a yearly basis is: II > I > III > IV. Using a percentage of similarity index it is concluded that Sites I and II are very similar. Site III is intermediate while Site IV is quite different. A number of examples of restricted distributions are cited. These examples illustrate that differences in longitudinal distribution are important in ecological segregation. Herbivorous stoneflies (suborder Filipalpia) comprise a greater proportion of the fauna at the upper site while predaceous stoneflies (Setipalpia) predominate in the lower areas. Water depth and amounts of leaves and silt are important factors in determining the distribution of stoneflies. Most species are abundant in leaf drifts. Microhabitat selection does not appear to be rigorous.

  Citation × Citation Citation Abstract Copy Title: Granary-site selection by acorn woodpeckers in Benton County, Oregon Author: Johnson, Eric M. The acorn woodpecker (Melanerpes formicivorus) is among the most common primary cavity nesters of the Oregon white oak (Quercus garryana) woodlands. Understanding their selection of granary sites is important in evaluating habitat quality and management actions. I hypothesized that granary locations would be consistent with the optimal foraging theory. Site characters were selected that were hypothesized to affect granary profitability. I compared site characteristics of granaries and non-granaries within the home ranges of 20 colonies in Benton County, Oregon during the winter of 2001. Granaries had greater oak basal area (x*=104 ± 16 dm2), shorter brush height (x*=-26 ± 7 cm), larger diameter at breast height (dbh) (x*=l1 ± 4 cm). Of 14 a priori models considered, I determined that the Forage Model was the best predictor of granary presence. This model is based solely on the oak basal area variable, a measure of potential acorn production. Increased acorn production in the vicinity of granaries is likely beneficial to the birds because minimal effort is expended in caching maximum forage.

  Citation × Citation Citation Abstract Copy Title: Classification of oak vegetation in the Willamette Valley Author: Fitzpatrick, Greg, Kertis, Jane, Alverson, Ed, Buechling, Arne A plant community classification was developed describing the comprehensive variation of oak vegetation currently occupying the Willamette Valley Ecoregion of western Oregon. Multivariate statistical analyses were used to classify field collected floristic and habitat data. Field sampling targeted minimally managed, homogenous vegetation stands with a significant oak component occupying at least 0.5 ha. Potential habitat locations were identified from local expert knowledge, data from The Nature Conservancy’s previous conservation planning efforts, and an interpretation of high resolution NAIP imagery. Potential oak habitats were digitized in a GIS and a random selection of sites stratifying significant environmental gradients was generated in order capture the range of oak habitat variability. Precise sample plot locations were predetermined and established at digitized stand centroids. Field sampling was based on relevé plot data collection methods and included ocular estimates of species cover. A total of 350 stands of oak vegetation were sampled over two field seasons. Two-way indicator species analysis (TWINSPAN) was used as an exploratory tool to identify potential patterns in species cover data and Detrended Correspondence Analysis (DCA) was used to delimit final plant community types. Nine vegetation classes were described from ordinations including seven forest / woodland types and two savannas Title: Classification of oak vegetation in the Willamette Valley Author: Fitzpatrick, Greg, Kertis, Jane, Alverson, Ed, Buechling, Arne A plant community classification was developed describing the comprehensive variation of oak vegetation currently occupying the Willamette Valley Ecoregion of western Oregon.
