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...

Genomic Resources for Phylogenetics, Species Delimitation, and Geographic Localization of Neotropical Tree Species Cedrela odorata L. (Meliaceae)

Creator:: Finch, Kristen N.
Abstract:: Biodiversity loss is of global concern, and is due in part to deforestation and high consumer demand for wood and wood products. The neotropical tree species Cedrela odorata (“Spanish cedar” or “cedro”) is economically valuable for its wood and faces threats of overexploitation. Due to strong similarities in wood features...

The Role of Intraspecific Functional Trait Variation in the Differential Decline of Meadow Species Following Conifer Encroachment

Creator:: Celis, Jessica
Abstract:: In the Oregon Cascade Range, conifer encroachment has reduced the extent of mountain meadows by as much as 50% since the mid-1940s. Although encroachment results in a general decline of meadow species abundance and diversity, species differ in their sensitivities to encroachment: some show rapid declines whereas others persist in...

Spatio-Temporal Patterns of Tree Establishment in the M1 Meadow of the H.J. Andrews Experimental Forest

Creator:: Jones, Katherine E.
Abstract:: Montane meadows in the Cascade Range of Oregon have been declining due to tree establishment since records began. Montane meadow complexes in the H.J. Andrews Experimental Forest shrank by 60 to 75% from 1949 to 2005, but fine scale temporal and spatial processes of tree establishment in these meadows are...

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...

Exotic plant species dynamics from 1994 to 2005 on road networks in forested landscapes of western Oregon

Creator:: Sheehy, Samantha
Abstract:: Although the Pacific Northwest has the least proportion of non-native plant species in relation to other regions of North America, exotic species continue to spread into mountainous areas, including the Cascade Range. In a forested landscape, road networks can act as corridors for exotic plant dispersal and establishment, helping species...

Conduit or Contributor? The Role of Media in the California End-of-Life Option Act Policy Process

Creator:: Choi, Junghwa
Abstract:: Whether media plays a contributory or a conduit role in the policy process has been a salient focus among policy scholars. If media plays a contributory role in the policy process, it not only shares similar policy core beliefs with advocacy coalitions, but also drafts and disseminates stories including policy...

Geographic distributions of prey of the northern spotted owl in the central western Cascades, Oregon, 1988-2009

Creator:: Smoluk, Alexis
Abstract:: Spatial variation in the diet of the northern spotted owl (Strix occidentalis caurina) influences owl home ranges, and understanding this relationship will aid managers in forest management prescriptions that influence spotted owl recovery. This study describes the spatial variation in owl diet based on 4183 prey collected at 114 owl...

The historic and contemporary ecology of western Cascade meadows : archeology, vegetation, and macromoth ecology

Creator:: Highland, Steven A.
Abstract:: Montane meadows in the western Cascades of Oregon occupy approximately 5% of the landscape, but contribute greatly to the region's biodiversity. Western Cascades meadows are dynamic parts of the landscape and have contracted by over 50% in the past two hundred years in the HJ Andrews Experimental Forest (hereafter Andrews...

Precipitation-snowmelt timing and snowmelt augmentation of large peak flow events, western Cascades, Oregon

Creator:: Jennings, Keith S.
Abstract:: Despite advances in the understanding of rain-on-snow storms and their resulting peak flows, little is understood about the response of snowmelt to precipitation and the relative timing of the two at multiple temporal scales within such events. To address this issue, climate, snowmelt, and streamflow data were analyzed for 26...
