Distribution of bats in Southeast Alaska and selection of day-roosts in trees by Keen’s myotis on Prince of Wales Island, Southeast Alaska

Creator:: Boland, Julia L.
Abstract:: We conducted capture and acoustic surveys for bats in six areas along a latitudinal gradient in Southeast Alaska from mid-May to September in 2005 and we continued surveys on Prince of Wales Island from mid-May to September in 2006. We determined the level of effort required to catch each species...

Regeneration and growth of several canopy tree species in the Maya Forest of Quintana Roo, Mexico : the role of competition and microhabitat conditions

Creator:: Sorensen, NaDene S.
Abstract:: We evaluated the regeneration behavior and early growth rates of 10 non-pioneer canopy tree species in medium-height, semi-evergreen dry tropical forest in Quintana Roo, Mexico. These species provide timber and non-timber forest products for local communities and include evergreen and deciduous species with varied dispersal mechanisms. The species were Coccoloba...

Population demography, resource use, and movement in cooperatively breeding Micronesian Kingfishers

Creator:: Kesler, Dylan C.
Abstract:: Island systems and species are susceptible to extinction because of their small population size and an ecological naiveté from an evolutionary past lacking strong competition and predation. For example, only one-fifth of the world’s bird species occur on islands, yet more than 90% of the avian extinctions witnessed during historic...

Douglas-fir hydraulic architecture and relationships among xylem properties at multiple scales via a Bayesian analysis

Creator:: Dunham, Sonya M.
Abstract:: This study investigated variation in xylem anatomy, hydraulic properties, and the relationship between anatomy and properties within Douglas-fir trees at multiple scales. The hierarchical scales in the study included fertilization treatments (fertilized and unfertilized), trees within the treatments, and positions within the trees. Tracheid diameter, tracheid length, percent latewood, number...

Expression and Function of Populus Homologs to TERMINAL FLOWER 1 Genes: Roles in Onset of Flowering and Shoot Phenology

Creator:: Mohamed, Rozi
Abstract:: We isolated and characterized the expression of two genes from Populus trichocarpa that are homologous to the TERMINAL FLOWER 1 (TFL1) gene from the model annual plant Arabidopsis. In Arabidopsis, overexpression of the TFL1 gene extends the vegetative growth phase, and the homozygous mutant tfl1 allele causes early flowering and...

Climate, management, and forest type influences on carbon dynamics of West-Coast US forests

Creator:: Hudiburg, Tara M.
Abstract:: Net uptake of carbon from the atmosphere (net ecosystem production, NEP) is dependent on climate, disturbance history, management practices, forest age, and forest type. To improve understanding of the influence of these factors on forest carbon flux in the western U.S., a combination of federal inventory data and supplemental ground...

Behavioral responses of Rocky Mountain Elk (Cervus elaphus) to recreational disturbance

Creator:: Naylor, Leslie M.
Abstract:: I measured responses of free-ranging Rocky Mountain elk (Cervus elaphus) to recreational disturbance at Starkey Experimental Forest and Range, Oregon from April to October, 2003 and 2004. Resting, feeding, and travel activities of 13 cow elk were recorded at 5-minute intervals using Actiwatch™ motion sensors. Elk were subjected to four...

Marine habitat use of black-footed and Laysan albatrosses during the post-breeding season and their spatial and temporal overlap with commercial fisheries

Creator:: Fischer, Karen Naess
Abstract:: Incidental bycatch in commercial fisheries has been identified as a threat to black-footed albatrosses (Phoebastria nigripes) and Laysan albatrosses (P. immutabilis). Effective long-term conservation of these albatrosses necessitates a thorough understanding of their marine distribution, which marine habitats are selected during foraging, and where they are most likely to interact...

Advancing marine reserve science : from field experiments to marine conservation planning tools

Creator:: Leslie, Heather M.
Abstract:: This dissertation focuses on science relevant to the design and implementation of marine reserves. The chapters explore a range of topics related to among-site variation in population, community, and ecosystem dynamics. My results demonstrate the value and feasibility of integrating this knowledge into more comprehensive conservation and management approaches. While...

Riparian litter inputs to streams in the central Oregon Coast Range

Creator:: Hart, Stephanie K.
Abstract:: Riparian zone vegetation can influence terrestrial and aquatic food webs through variations in the amounts, timing, and nutritional content of leaf and other litter inputs. Differences in vegetation composition and density, as well as riparian topography, may modulate the strength and quality of these inputs. Changes in inputs to small...
