Analyzing fire mosaics in temperate coniferous forests with GIS and remote sensing

Creator:: Kushla, John D.
Abstract:: This investigation on fire mosaics addressed several aspects: (1) quantifying the role of terrain variables in fire-related mortality and historical mean fire return interval (MFRI), (2) comparing post-burn Landsat Thematic Mapper (TM) imagery, TM difference imagery, and aerial photo interpretation to map forest survival after wildfire, and (3) to describe...

Annual bluegrass (Poa annua L.) emergence under different residue management practices in perennial ryegrass and determination of resistant and susceptible annual bluegrass germination under controlled temperature and moisture

Creator:: Schuster, Matthew D.
Abstract:: With the loss of field burning the amount of crop residue that remains in perennial ryegrass fields has increased. As the amount of crop residue remaining in the field increases so does annual bluegrass. This has resulted in the increased use of herbicides to control annual bluegrass. However, this increased...

The effect of miombo and dambo soil transfers on early seedling growth of Bauhinia petersiana Bolle., Cassia spectabilis D.C., and Calliandra calothyrsus Meissn. on degraded miombo sites

Creator:: Volk, John
Abstract:: Miombo woodland and dambo grassland soils were selected to study the effect of soil transfer on early growth of B. petersiana, C. spectabilis, and C. calothyrsus on degraded sites in northern Zambia. The experiment was conducted on previously slash and burned, cultivated, and abandoned sites. Both sterile and unsterile miombo...

Effect of nitrogen fertilizer and irrigation on Acacia senegal seedling biomass and photosynthesis

Creator:: Warrag, Esam Eldin I.
Abstract:: Seedlings of Acacia senegal were grown in a glass greenhouse to study the effect of nitrogen and irrigation regimes on dry matter production and allocation to different plant organs, net photosynthesis per unit leaf area, and nitrogen content in the different plant organs. Ammonium nitrate (NH4NO3) was used in this...

The phytotoxic effects of herbicide and adjuvant application by physiological timing on the woody shrub salal (Gaultheria shallon)

Creator:: Downs, Theodore
Abstract:: Salal is plant species that is native to forestland throughout the PNW and northern California that has been identified as a competitor to early crop tree development. This study consisted of a field and a radioisotope laboratory study to test four commonly used herbicides on salal (imazapyr, triclopyr, glyphosate, and...

Range-wide patterns of allozyme variation in Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco)

Creator:: Li, Peng, 1961-
Abstract:: One hundred and four seed sources from throughout the range of Douglas-fir (Pseudotecia menzieaii (Plirb.) Franco) were analysed at 20 enzyme loci to determine patterns of genetic variation and to examine intraspecific phylogeny. On average the seed sources were polymorphic at 37 percent of the loci (range 5.0-65.0), with mean...

Classifying Low Streamflow Parameters in Coastal Southeast Alaska Using Game Cameras and Random Forest Models

Creator:: Lanphier, Kari
Abstract:: Southeast Alaska is located on the traditional territory of the Lingít, Haida, and Tsimshian People. It is comprised of the largest temperate rainforest in the world, with subregions receiving over 500 cm of rain annually. Climate change is predicted to alter the region's timing, type, and magnitude of precipitation and...

Effects of Stage 0 Stream Restoration on Aquatic Macroinvertebrate Production

Creator:: Jennings, Jeremy C.
Abstract:: Contemporary stream restoration efforts increasingly prioritize restoring natural stream processes to regain lost ecosystem functions. Stage 0 stream restoration resets disturbed, channelized streams to a theoretical pre-disturbance state (“stage zero”). It is assumed that this valley-scale restoration/disturbance will restore natural abiotic and biotic processes, leading to greater primary and secondary...

Physiological characterization of the mixotrophic dinoflagellate Amphidinium carterae

Creator:: Tornberg, Emma C.
Abstract:: Marine primary production can be modeled and estimated using remotely-observable physiological signatures such as chlorophyll and carbon. Current models are based on strict physiological relationships based on photoautotrophic phytoplankton, and discrepancies between modeled and in situ data may stem from unaccounted-for physiological deviations from photoautotrophy. Mixotrophic phytoplankton can obtain energy...
