Effects of Forest Harvest, Floods, and Wildfire on Bedload Export from Headwater Catchments in the H.J. Andrews Experimental Forest, 1957 – 2022

Creator:: Wright, Charles M.
Abstract:: This study examined how annual bedload export volume and bedload characteristics were related to disturbances including logging, floods, debris slides, and wildfires over 48 to 65-year periods in small, steep catchments in conifer forests of the western Cascade Range, Oregon. Bedload – the material rolling, sliding, or saltating along the...

Time of insemination and oviposition as related to fertility of female domestic fowl

Creator:: Johnston, Norman Paul
Abstract:: Hens were artificially inseminated at 8:00 a.m., 4:00 p.m. and 11:50 p.m. Fertility was found to be significantly lower after 8:00 a.m. inseminations than after 4:00 p.m. or 11:50 p.m. inseminations for 2 to 6 days, 2 to 9 days and 10 to 17 days following inseminations. Slightly higher fertility...

Fertility in the domestic hen as related to the events of the reproductive cycle

Creator:: Hughes, Buddy Lee, 1942-
Abstract:: To observe the effects of oviposition as related to time of insemination on fertility, four trials were conducted in which individually caged White Leghorn hens were artificially inseminated with 0.05 cc of undiluted mixed semen obtained from 4 to 5 cockerels. These inseminations were made at 9:45 a.m. , 10:00...

Effect of restriction of water intake on growth and feed consumption of broiler chickens

Creator:: Kellerup, Stanley Ulrick
Abstract:: A trial was conducted to determine the effects of increasing levels of water restriction on body weight, feed consumption, feed conversion and mortality of broiler chicks to eight weeks of age. In addition, the effects of water restriction on water:feed ratios, water consumption per pound of body weight and on...

Combustion Characteristics of a Jet Fuel and its Surrogate in MILD Conditions

Creator:: Weide, Parker D.
Abstract:: This research seeks to identify how changes in temperature and oxygen concentration in the reaction zone affects liftoff heights for moderate or intense low-oxygen dilution (MILD) combustion of a jet fuel and a surrogate fuel. MILD combustion offers a method of burning fuels with reduced CO and NOx production by...

The Role of Emerging Pathogens in Amphibian Population Declines : Experimental Evidence

Creator:: Hambalek, Natalie M.
Abstract:: Rapid rates of biodiversity loss have supported the notion that Earth is experiencing a sixth major extinction event. The causes of worldwide biodiversity loss are multifaceted and context dependent. One of the most prominent groups experiencing population declines and extinctions are amphibians. Several pathogens and their associated diseases are especially...

Buzzing Bolbomyiidae and Air Temperature Monitoring Methods: Investigating Long-Term Ecological Data from the H.J. Andrews Experimental Forest

Creator:: Schmidt, Stephanie A.
Abstract:: The short-term duration of most ecological studies can make it difficult to capture the long-term dynamics of ecosystems and populations. Infrequent or high-impact events can be missed, or erroneously documented as baselines. Long-term ecological research enables a deeper understanding of complex processes, provides a foundation for future insights, and can...

The Effects of Nitrate and a Pathogenic Fungus, Batrachochytrium dendrobatidis, on Amphibians

Creator:: Negru, Delia
Abstract:: The current rate of global biodiversity loss and extinctions is unparalleled and a major concern. Freshwater organisms are facing particularly rapid rates of biodiversity loss. Amphibians, which require an aquatic environment for part of their life cycle, are one of the most vulnerable vertebrate groups. Amphibians are experiencing population declines,...
