Branching processes and partial differential equations

Creator:: Orum, John Christopher
Abstract:: The recursive and stochastic representation of solutions to the Fourier transformed Navier-Stokes equations, as introduced by [34], is extended in several ways. First, associated families of functions known as majorizing kernels are analyzed, in light of their apparently essential role in the representation. Second, the theory is put on a...

Invasiveness of plant pathogens depends on the spatial scale of host distribution

Creator:: Mikaberidze, Alexey, Mundt, Christopher C., and Bonhoeffer, Sebastian
Abstract:: Plant diseases often cause serious yield losses in agriculture. A pathogen’s invasiveness can be quantified by the basic reproductive number, R₀. Since pathogen transmission between host plants depends on the spatial separation between them, R₀ is strongly influenced by the spatial scale of the host distribution.We present a proof of...

Mixed-Severity Fire Effects on Biological Legacies and Vegetation Response in Pseudotsuga Forests of Western Oregon's Central Cascades, USA

Creator:: Dunn, Christopher J.
Abstract:: Mixed-severity fire occurrence is increasingly recognized in Pseudotsuga forests of the Pacific Northwest, but questions remain about how tree mortality varies, and forest structure is altered, across the disturbance gradient observed in these fires. Therefore, we sampled live and dead biological legacies at 45 one ha plots, with four 0.10...

Intra‐populational variation of ejaculate traits and sperm depletion in red‐sided garter snakes

Creator:: Friesen, Christopher R., Squire, Mattie K., and Mason, Robert T.
Abstract:: Female sexual promiscuity is a prevalent element of mating systems. One consequence of female sexual promiscuity is that male‐male competition often continues post‐copulation within the female’s reproductive tract. According to theory, the number of sperm a male inseminates relative to his rivals strongly predicts his fertilization success. However, sperm quality...

The GIS Professional Ethics Project: Practical Ethics Education for GIS Professionals

Creator:: DiBiase, David, Harvey, Francis, Goranson, Christopher, and Wright, Dawn
Abstract:: Teaching GIS involves teaching ethical and moral thinking as a distinct engagement with the use, applications, and responsibilities of GIS professionals. Over the past 20 years scholars (particularly those affiliated with the discipline of Geography) have contributed critiques of the instrumental nature of GIS as well as reflective case studies...

Females remate more frequently when mated with sperm-deficient males

Creator:: Friesen, Christopher R., Uhrig, Emily J., and Mason, Robert T.
Abstract:: Polyandry is a source of sexual conflict and males often try to limit female promiscuity. Consequently, male manipulation of receptivity via antiaphrodisiacs and copulatory plugs that prevent female remating can be a source of sexual conflict. This sexual conflict may be intensified when females must remate for fertility insurance. Male...

The Art and Craft of John Williams

Creator:: Lincoln, Danae A.
Abstract:: The intent of this paper is to bring more attention to the mastery involved with film composition as an art form. The research focuses specifically on the life, style, influences, and works of John Williams as a conductor, film composer, and composer. It addresses his biography, filmography, and working relationships,...

Assessing Post-fire Tree and Understory Vegetation Response to a Mixed-severity Fire Gradient in the Klamath Mts., Oregon, USA

Creator:: Terzioglu, Cihat
Abstract:: Severe wildfires are increasing in the western United States, impacting vegetation structure, and in turn, forest regeneration conditions. These wildfires are also raising a substantial amount of scientific and management concern regarding the resilience of forested ecosystems, or the ability of the ecosystem to return to a pre-fire condition. This...

Populations of aspen (Populus tremuloides Michx.) with different evolutionary histories differ in their climate occupancy

Creator:: Greer, Burke T., Still, Christopher, Howe, Glenn T., Tague, Christina, and Roberts, Dar A.
Abstract:: Quaking aspens (Populus tremuloides Michx.) are found in diverse habitats throughout North America. While the biogeography of aspens' distribution has been documented, the drivers of the phenotypic diversity of aspen are still being explored. In our study, we examined differences in climate between northern and southwestern populations of aspen, finding...

A climate of uncertainty: accounting for error in climate variables for species distribution models

Creator:: Stoklosa, Jakub, Daly, Christopher, Foster, Scott D., Ashcroft, Michael B., and Warton, David I.
Abstract:: 1. Spatial climate variables are routinely used in species distribution models (SDMs) without accounting for the fact that they have been predicted with uncertainty, which can lead to biased estimates, erroneous inference and poor performances when predicting to new settings – for example under climate change scenarios. 2. We show...
