Evaluation of Pacific Lamprey Entosphenus Tridentatus Anatomical Structures as Records of Age and Isotope Histories

Creator:: Pelekai, Keala N.
Abstract:: The anadromous Pacific Lamprey (Entosphenus tridentatus) is a biologically and culturally important species native to the North Pacific Ocean and its adjacent freshwater tributaries. Pacific Lamprey have experienced declines in abundance and distribution throughout their native range, highlighting a need for further research on the species to better inform conservation...

Distributed inference-based multi-robot exploration

Creator:: Smith, Andrew J. and Hollinger, Geoffrey A.
Abstract:: This work proposes a technique for distributed multi-robot exploration that leverages novel methods of map inference. The inference technique uses observed map structure to infer unobserved map features. The team then coordinates to explore both the inferred and observed portions of the map. Individual robots select exploration poses by accounting...

Assessing earth system model predictions of C-4 grass cover in North America: From the glacial era to the end of this century

Creator:: Still, Christopher J., Cotton, Jennifer M., and Griffith, Daniel M.
Abstract:: Aim C-4 grasses are distinct from C-3 grasses, because C-4 grasses respond in a different manner to light, temperature, CO2 and nitrogen and often have higher resource-use efficiencies. C-3 and C-4 grasses are typically represented in earth system models (ESMs) by different plant functional types (PFTs). The ability of ESMs...

Early to Late Holocene Surface Exposure Ages From Two Marine-Terminating Outlet Glaciers in Northwest Greenland

Creator:: Reusche, Melissa M., Marcott, Shaun A., Ceperley, Elizabeth G., Barth, Aaron M., Brook, Edward J., Mix, Alan C., and Caffee, Marc W.
Abstract:: Terrestrial chronologies from southern Greenland provide a detailed deglacial history of the Greenland Ice Sheet (GIS). The northern GIS margin history, however, is less established. Here we present surface exposure ages from moraines associated with two large outlet glaciers, Petermann and Humboldt, in the northwestern sector of the GIS. These...

Ecohydrologic Connections in Semiarid Watershed Systems of Central Oregon USA

Creator:: Ochoa, Carlos G., Caruso, Phil, Ray, Grace, Deboodt, Tim, Jarvis, W. Todd, and Guldan, Steven J.
Abstract:: An improved understanding of ecohydrologic connections is critical for improving land management decisions in water-scarce regions of the western United States. For this study, conducted in a semiarid (358 mm) rangeland location in central Oregon, we evaluated precipitation-interception-soil moisture dynamics at the plot scale and characterized surface water and groundwater...

Social Vulnerability Index for the state of Oregon (2020 ACS data)

Creator:: Reilley, Caitlyn and Crandall, Mindy
Abstract:: Senate Bill 762, Oregon’s 2021 omnibus wildfire bill, directed Oregon State University to conduct a wildfire risk assessment including mapping socially vulnerable communities to help inform decisions and allocate resources related to state wildfire prevention, response, and recovery. This dataset was curated to identify socially vulnerable communities and largely follows...

Recovery of ectomycorrhizal fungus communities fifteen years after fuels reduction treatments in ponderosa pine forests of the Blue Mountains, Oregon

Creator:: Hart, Benjamin T. N., Smith, Jane E., Luoma, Daniel L., and Hatten, Jeff A.
Abstract:: Managers use restorative fire and thinning for ecological benefits and to convert fuel-heavy forests to fuel-lean landscapes that lessen the threat of stand-replacing wildfire. In this study, we evaluated the long-term impact of thinning and prescribed fire on soil biochemistry and the mycorrhizal fungi associated with ponderosa pine (Pinus ponderosa)....

Characterizing neutral and adaptive genomic differentiation in a changing climate: The most northerly freshwater fish as a model

Creator:: O'Malley, Kathleen G., Vaux, Felix, and Black, Andrew N.
Abstract:: Arctic freshwater ecosystems have been profoundly affected by climate change. Given that the Arctic charr (Salvelinus alpinus) is often the only fish species inhabiting these ecosystems, it represents a valuable model for studying the impacts of climate change on species life‐history diversity and adaptability. Using a genotyping‐by‐se‐ quencing approach, we...

Novel microRNAs are associated with population divergence in transcriptional response to thermal stress in an intertidal copepod

Creator:: Graham, Allie M. and Barreto, Felipe S.
Abstract:: The role of gene expression in adaptation to differing thermal environments has been assayed extensively. Yet, in most natural systems, analyses of gene expression reveal only one level of the complexity of regulatory machineries. MicroRNAs (miRNAs) are small noncoding RNAs which are key components of many gene regulatory networks, and...

Sex matters: Otolith shape and genomic variation in deacon rockfish (Sebastes diaconus)

Creator:: Vaux, Felix, Rasmuson, Leif K., Kautzi, Lisa A., Rankin, Polly S., Blume, Matthew T. O., Lawrence, Kelly A., Bohn, Sandra, and O'Malley, Kathleen G.
Abstract:: Little is known about intraspecific variation within the deacon rockfish (Sebastes di‐ aconus), a recently described species found in the northeast Pacific Ocean. We in‐ vestigated population structure among fish sampled from two nearshore reefs (Siletz Reef and Seal Rock) and one offshore site (Stonewall Bank) within a <50‐km2 area...
