Automated quantification of distributed landslide movement using circular tree trunks extracted from terrestrial laser scan data

Creator:: Conner, Jeremy C. and Olsen, Michael J.
Abstract:: This manuscript presents a novel algorithm to automatically detect landslide movement in a forested area using displacements of tree trunks distributed across the landslide surveyed repeatedly using terrestrial laser scanning (TLS). Common landslide monitoring techniques include: inclinometers, global position system (GPS), and interferometric synthetic aperture radar (InSAR). While these techniques...

Role of propagule pressure and priority effects on seedlings during invasion and restoration of shrub-steppe

Creator:: Schantz, Merilynn C., Sheley, Roger L., and James, Jeremy J.
Abstract:: Plant invasion and restoration outcomes are largely driven by the timing and magnitude of seed dispersal, and by the performance of dispersed species in an environment. Because seed dispersal controls recruitment of newly arriving species and facilitates safe site occupation, assembly will differ depending on seed dispersal processes and variable...

The Mediating Role of Intention and Stages of Change in Physical Activity Among Adults with Physical Disabilities: An Integrative Framework

Creator:: Kosma, Maria, Ellis, Rebecca, Cardinal, Bradley J., Bauer, Jeremy J., and McCubbin, Jeffrey A.
Abstract:: The study’s purpose was to identify the mediating role of intention and the stages of change (SOC) in physical activity (PA) over a 6-month period using two models (Theory of Planned Behavior [TPB] and TPB/SOC). Participants were 143 adults with physical disabilities (70.68% response rate; M age = 46.03). The...

Psychosocial Determinants of Stages of Change and Physical Activity Among Adults With Physical Disabilities

Creator:: Kosma, Maria, Gardner, Rebecca Ellis, Cardinal, Bradley J., Bauer, Jeremy J., and McCubbin, Jeffrey A.
Abstract:: A high proportion of individuals with disabilities remain physically inactive. Therefore, this study (web-based survey) investigated the relationships between the Transtheoretical Model (TTM) and physical activity among 224 adults with physical disabilities (M age = 45.4 years, SD = 10.78, females = 71%). Additionally, the most important TTM predictors of...

Do key dimensions of seed and seedling functional trait variation capture variation in recruitment probability?

Creator:: Larson, Julie E., Sheley, Roger L., Hardegree, Stuart P., Doescher, Paul S., and James, Jeremy J.
Abstract:: Seedling recruitment is a critical driver of population dynamics and community assembly, yet we know little about functional traits that define different recruitment strategies. For the first time, we examined whether trait relatedness across germination and seedling stages allows the identification of general recruitment strategies which share core functional attributes...

Effects of elevated CO₂ levels on eggs and larvae of a North Pacific flatfish

Creator:: Hurst, Thomas P., Laurel, Benjamin J., Mathis, Jeremy T., and Tobosa, Lauren R.
Abstract:: The Bering Sea and Gulf of Alaska support a number of commercially important flatfish fisheries. These high latitude ecosystems are predicted to be most immediately impacted by ongoing ocean acidification, but the range of responses by commercial fishery species has yet to be fully explored. In this study, we examined...

Mineral protection of soil carbon counteracted by root exudates

Creator:: Keiluweit, Marco, Bougoure, Jeremy J., Nico, Peter S., Pett-Ridge, Jennifer, Weber, Peter K., and Kleber, Markus
Abstract:: Multiple lines of existing evidence suggest that climate change enhances root exudation of organic compounds into soils. Recent experimental studies show that increased exudate inputs may cause a net loss of soil carbon. This stimulation of microbial carbon mineralization ('priming') is commonly rationalized by the assumption that exudates provide a...

Seed and seedling traits affecting critical life stage transitions and recruitment outcomes in dryland grasses

Creator:: Larson, Julie E., Sheley, Roger L., Hardegree, Stuart P., Doescher, Paul S., and James, Jeremy J.
Abstract:: 1. Seeding native plants is a key management practice to counter land degradation across the globe, yet the majority of seeding efforts fail, limiting our ability to accelerate ecosystem recovery. 2. Recruitment requires transitions through several seed and seedling stages, some of which may have overriding influences on restoration outcomes....

Deploying initial attack resources for wildfire suppression: spatial coordination, budget constraints, and capacity constraints

Creator:: Lee, Yohan, Fried, Jeremy S., Albers, Heidi J., and Haight, Robert G.
Abstract:: We combine a scenario-based, standard-response optimization model with stochastic simulation to improve the efficiency of resource deployment for initial attack on wildland fires in three planning units in California. The optimization model minimizes the expected number of fires that do not receive a standard response-defined as the number of resources...

What drives interaction strengths in complex food webs? A test with feeding rates of a generalist stream predator

Creator:: Preston, Daniel L., Henderson, Jeremy S., Falke, Landon P., Segui, Leah M., Layden, Tamara J., and Novak, Mark
Abstract:: Describing the mechanisms that drive variation in species interaction strengths is central to understanding, predicting, and managing community dynamics. Multiple factors have been linked to trophic interaction strength variation, including species densities, species traits, and abiotic factors. Yet most empirical tests of the relative roles of multiple mechanisms that drive...
