Ecology of Craterellus tubaeformis in western Oregon

Creator:: Trappe, Matthew James
Abstract:: Craterellus tubaeformis is a small to medium-sized forest mushroom that is fairly common in the Douglas-fir/western hemlock forests of the Pacific Northwestern United States and is most often associated with decayed coarse woody debris. In this study, the mycorrhizae of Craterellus tubaeformis in western Oregon is identified by DNA analysis...

Systematics, phylogeny, and ecology of Gomphus sensu lato

Creator:: Giachini, Admir J.
Abstract:: The nomenclatural history of Gomphus sensu lato began with Persoon in 1797. Over 200 years species of Gomphus sensu lato have been variously classified also under Cantharellus, Craterellus, Chloroneuron, Chlorophyllum, Gloeocantharellus, Nevrophyllum, and Turbinellus. Species of Gomphus sensu lato have been historically characterized as having aboveground fruiting, fleshy basidiomata with...

The biology and ecology of Potentilla recta in the Blue Mountains of northeastern Oregon

Creator:: Tuitele-Lewis, Jamison
Abstract:: Two experiments were conducted on the invasive plant species Potentilla recta in northeastern Oregon to investigate both biological and ecological characteristics of the species. Growth analysis was conducted on the plant at three sites over a period of two years (2002 and 2003). Relative growth rate (RGR) was calculated for...

The ecology and management of invasive plant species on tropical islands

Creator:: Hooper, Carolina
Abstract:: Tropical island ecosystems have proven to be inordinately vulnerable to invasions by exotic plants and animals. Today these islands only contain small remnant populations of the original flora and fauna, and these populations are facing increasing pressure from invasive plants. This paper attempts to answer four important questions whose solutions...

The ecology of riparian ecosystems of Northeast Oregon : shrub recovery at Meadow Creek and the structure and biomass of headwater Upper Grande Ronde ecosystems

Creator:: Case, Richard L.
Abstract:: Riparian ecosystems play numerous and essential roles related to the quality and flow of water, and food/habitat for fish, and varieties of wildlife. Due to lateral and linear linkages throughout the landscape, these zones influence the integrity of the terrestrial as well as the entire aquatic-riverine ecosystem. Since Euro-American settlement...

Mycorrhizal status of post-fire Pezizales

Creator:: Fujimura, Kei E.
Abstract:: Post-fire Pezizales often fruit seasonally approximately six weeks after a fire in successional groups over the course of two years. Two methods, pure culture synthesis and PCR-based identification, were used to determine if some of these species were mycorrhizal. Eleven fungal isolates, Anthracobia melaloma, Gyromitra infula, Helvella compressa, Morchella sp.,...

Beaver ecology in Bridge Creek, a tributary to the John Day River

Creator:: Maenhout, Julie L. (Harper)
Abstract:: The American beaver (Castor canadensis) was nearly extirpated by the late 1800's due to the fur trade. Due to reintroduction efforts, it now occupies much of its former range. Beavers are a keystone species and ecosystem engineers, greatly influencing riparian and instream habitats through selective harvesting of plant materials and...

Silviculture-ecology of three native California hardwoods on high sites in north central California

Creator:: McDonald, Philip M.
Abstract:: Pacific madrone, tanoak, and California black oak are the most economically promising native California hardwoods. Volume and value data indicate upward trends in growing stock levels and prices received for their products. These trends are likely to continue. They suggest research is particularly needed for: (1) seed fall and regeneration,...

Effects of vegetation and soil organisms on soil nutrient dynamics in subalpine Abies lasiocarpa forests

Creator:: Johnson, Kathleen A., 1955-
Abstract:: The broadest goal of the research covered in this thesis was to contribute to our limited knowledge of high elevation forest soil ecology. Based on the reeds of funding agencies, specific objectives were to examine 1) how climate-induced Abies lasiocarpa ([Hook.] Nutt.) forest expansion affects soil nutrient pools, 2) the...

Functional relationships among vegetation, nocturnal insects, and bats in riparian areas of the Oregon Coast Range

Creator:: Ober, Holly K.
Abstract:: Vegetation provides food for many insects, and many insects serve as food for bats. We investigated the linkages among these three trophic levels in riparian areas throughout the Oregon Coast Range by examining the influence of vegetation cover, composition, and structure on the activity of nocturnal insects and bats, the...
