Drivers and Impacts of a Recent Annual Grass Invasion: Ventenata dubia and Fire in the Inland Northwest

Creator:: Tortorelli, Claire M.
Abstract:: Biological invasions threaten native biodiversity, alter ecosystem function, and are a major cause of economic losses across the planet. The most impactful invaders alter disturbance regimes and initiate state shifts to outside the historical range of variability of the ecosystem. Concern for ecological and economic losses has prompted a rapid...

Impacts of disturbance on the terrestrial carbon budget of North America

Creator:: Kasischke, Eric S., Amiro, Brian D., Barger, Nichole N., French, Nancy H. F., Goetz, Scott J., Grosse, Guido, Harmon, Mark E., Hicke, Jeffrey A., Liu, Shuguang, and Masek, Jeffrey G.
Abstract:: Because it is an important regulator of terrestrial carbon cycling in North America, extensive research on natural and human disturbances has been carried out as part of the North American Carbon Program and the CarboNA project. A synthesis of various components of this research was carried out, and the results...

Spatial patterns and trends of summertime low cloudiness for the Pacific Northwest, 1996-2017

Creator:: Dye, Alex W., Rastogi, Bharat, Clemesha, Rachel E. S., Kim, John B., Samelson, Roger M., Still, Christopher J., and Williams, A. Park
Abstract:: Summertime low clouds are common in the Pacific Northwest (PNW), but spatiotemporal patterns have not been characterized. We show the first maps of low cloudiness for the western PNW and North Pacific Ocean using a 22‐year satellite‐derived record of monthly mean low cloudiness frequency for May through September and supplemented...

An interdisciplinary framework for evaluating 19th century landscape paintings for ecological research

Creator:: Warren, Dana R., Loeb, Harper M., Betjemann, Peter, Munck, Isabel A., Keeton, William S., Shaw, David C., and Harvey, Eleanor J.
Abstract:: As we contemplate the future of forest landscapes under changing climate conditions and land-use demands, there is increasing value in studying historic forest conditions and how these landscapes have changed following past disturbances. Historic landscape paintings are a potential source of data on preindustrial forests with highly detailed, full-color depictions...

Understanding ecohydrological connectivity in savannas: a system dynamics modelling approach

Creator:: Miller, Gretchen R., Cable, Jessica M., McDonald, Alyson K., Bond, Barbara, Franz, Trenton E., Wang, Lixin, Gou, Si, Tyler, Anna P., Zou, Chris B., and Scott, Russell L.
Abstract:: Ecohydrological connectivity is a system level property that results from the linkages in the networks of water transport through ecosystems, by which feedbacks and other emergent system behaviours may be generated. We created a system dynamics model that represents primary ecohydrological networks to examine how connectivity between ecosystem components impacts...

A Review and Recommendations for Assessing Floodplain Vegetation Recovery Following Stage 0 and Beaver Dam Analog Restorations in the Pacific Northwest

Creator:: Colley, Lara K. M.
Abstract:: Floodplains are a significant and increasingly threatened ecosystem. As restoration projects are implemented more frequently in degraded floodplains, novel methods are emerging with a focus on restoring critical processes in which vegetation plays a key role. The purpose of this paper is two-fold: 1) to develop expectations for vegetation response,...

Spatial Patterns of Soil Moisture and the Relative Importance of Atmospheric Water Demand Versus Soil Moisture Availability in Limiting Late-summer Growth of Douglas-fir Under a Changing Climate

Creator:: Jarecke, Karla M.
Abstract:: The rapid pace of climate change is increasing tree mortality and highlighting the need to improve the mechanistic understanding of plant function under increased water stress. However, the processes that control soil moisture availability in steep mountainous terrain are poorly understood, as are the relative effects of atmospheric and soil...

Ecosystem Photosynthesis and Forest-Atmosphere Interactions Inferred from Carbonyl Sulfide

Creator:: Rastogi, Bharat
Abstract:: An increase in anthropogenic activities since the industrial revolution, primarily due to burning of fossil fuels and changes in land cover, has resulted in a steady increase in the global mean atmospheric CO2 concentrations. While there is unequivocal scientific evidence on global warming and its multidimensional impacts on natural and...

The Impact of Overlapping Forest Disturbance Across a Stream Network in Western Oregon: Harvesting, Wildfire and Post-Fire Management Effects on Stream Water Nitrate and Riparian Soil Nutrients

Creator:: McCredie, Katherine E.
Abstract:: Understanding the magnitude and longevity of wildfire effects in forested watersheds and subsequent impacts to downstream aquatic ecosystems and communities requires congruent investigation into post-fire aquatic and terrestrial processes. However, results from wildfire studies are often confounded by pre- and post-fire land management actions and based on either hydrologic or...

Potential effects of the invasive grass Ventenata dubia on elk habitat selection within the Starkey Experimental Forest and Range

Creator:: Crum, Keren-happuch R.
Abstract:: The invasive annual grass ventenata (Ventenata dubia) has become an increasing problem within western rangelands. Forage quality of areas infested with ventenata is reduced as its high silica content makes it unpalatable to livestock and wildlife. In the following study, I examined whether significant presence of ventenata affects habitat use...
