The phytoplankton and limnological characteristics of Lago Rupanco, Osorno, Chile

Creator:: Donoso, Teresa G.
Abstract:: Lago Rupanco is located in the central plain of Chile (Borgel, 1964) at 40° 50' S; 72° 30' W. It lies at 117 m above sea level, and corresponds to type 28c of Hutchinson's (1967) classification. Lago Rupanco is a warm, monomictic lake, with winter circulation and summer stratification. Physical,...

A G-type Lectin Receptor-like Kinase Associated with Septoria Canker Resistance and Susceptibility Described using Multi-omics and Biotechnology

Creator:: Lenz, Ryan R.
Abstract:: Managers of forest and plantation ecosystems are encountering growing problems involving plant pathogens and the expanding geographic ranges of these pathogens. Historically unexposed stands are exceptionally vulnerable when a non-native pathogen is introduced because these pathogens can cause devastating disease in a host population that lacks co-evolved resistance mechanisms. One...

A systematic study of Lathyrus vestitus Nutt. ex T. & G. (Fabaceae) and allied species of the Pacific Coast

Creator:: Broich, Steven L.
Abstract:: Eight species of Lathvrus (Fabaceae, Faboideae) endemic to the Pacific Coast of North America were the subject of a systematic investigation. Taxa studied included Lathvrus vestitus, Nutt. ex T. & G., L. laetif lorus Greene, L.. iepsonii Greene, £,. splendens Kellogg, L. polvphvllus, Nutt. ex T. & G., L. holochlorus...

Structure and Function of Foliar Fungal Communities of Populus trichocarpa Across its Native Range, Pacific Northwest, USA

Creator:: Barge, Edward G.
Abstract:: Foliar fungi – pathogens, endophytes, epiphytes – form taxonomically diverse communities that affect plant health and productivity. The composition of foliar fungal communities is variable at spatial scales both small (e.g., individual plants) and large (e.g., continents). However, few studies have focused on how environmental factors and host plant traits...

The effect of variation of some physical and chemical factors on the rate of growth of Botyrococcus braunii (Chlorophyta, Chlorococcales)

Creator:: Julian, Larry L.
Abstract:: The culture of the green alga Botryococcus braunii Kutz. obtained for use in this study was contaminated with bacteria and fungi. Algal colonies from this culture sonicated, rinsed and treated with penicillin (500 μg/ml), gentamicin sulfate (50 μg/ml) and amphotericin B (5 μg/ml) were found to be axenic when incubated...

The culture and biochemical analysis of some estuarine phytoplankton species

Creator:: DeMort, Carole Lyle
Abstract:: The biochemical composition of ten species of estuarine phytoplankton was determined. Studies were made of their growth in various culture media and of their relative value as food for oyster larvae. Nine of the species were isolated from Yaquina Bay, Oregon. An attempt was made to select species which commonly...

Plant-Pollinator Interactions in a Changing World: Cryptic Specialization, Pollinator Movement, and Landscape Genetics of Pollinator-Dependent Plants

Creator:: Gannon, Dustin G.
Abstract:: Plant-pollinator mutualisms are one of the most prevalent and economically important mutualisms in nature. Like many other ecological systems, plant-pollinator communities are threatened by anthropogenic activity, both directly (e.g., habitat conversion and fragmentation) and indirectly (e.g., climate change). While we are aware of many of the activities that adversely impact...

Physiological ecology and structure of benthic communities in a woodland stream

Creator:: Reese, Weldon Harold
Abstract:: This thesis reports a portion of a general ecological study of a stream under conditions of controlled flow and low levels of organic enrichment. It is concerned with the effects of experimental variations of light intensity and concentration of soluble organic enrichment imposed on seasonal variations of temperature and total...

The effects of logging on periphyton communities of coastal streams

Creator:: Hansmann, Eugene W. (Eugene William), 1933-
Abstract:: The purpose of this study was to investigate the effects of logging on the productivity, structure and biomass of a periphyton community developed in mountain streams. The three streams used in this investigation were located in the coast range of Lincoln County, Oregon. They were selected for similarity of habitat,...
