III. Introgressive mtDNA Transfer in Hybrid Lake Suckers (Teleostei, Catostomidae) in Western United States

Hybridization and introgression permitted gene transfer from Catostomus to Lake Suckers in modern and MioPliocene lakes of Western United States. Lake Sucker genera, Chasmistes, Deltistes, and Xyrauchen, were sympatric with species of Catostomus (riverine suckers) in four large modern lakes and many fossil lakes in the Great Basin, Klamath, and Columbia-Snake drainages, and also in the Colorado River. Unique morphological traits in Lake Suckers originally included distinctive lips, jaw bones, neurocranial bones, and gill-rakers, but many of the original traits were lost or partly lost, and the remaining phenotypes are mixtures of intermediate morphological traits grading toward local species of Catostomus.Peer Reviewedhttps://deepblue.lib.umich.edu/bitstream/2027.42/145184/1/MP 204no3.pdfDescription of MP 204no3.pdf : Main Articl

DEFINING, IDENTIFYING, AND ADDRESSING ANTISOCIAL BEHAVIOR IN CHILDREN AGES 4-7: THE PERSPECTIVES OF SELECTED ELEMENTARY PRINCIPALS IN A MIDWESTERN CITY SCHOOL DISTRICT

Children and youth are becoming involved in violent behavior at ever-younger ages. Early appearing behavior problems in a child’s school career are the single best predictor of delinquency in adolescence, gang membership, and adult incarceration. The purpose of this research was to identify successful interventions used by selected elementary principals which positively changed antisocial behavior in a kindergarten child. Face-to-face interviews were conducted with six elementary principals. The participants were chosen based on their district’s view of their success and were also chosen due to the low social economic status of the children in their building. Seven themes emerged from the interviews: the importance of parent involvement; building relationships with children; regular education functions; more restrictive environments; experience and training; early intervention; and all-day kindergarten. The results of the study demonstrated a need for the training of elementary principals in the areas of defining and identifying antisocial behavior. Principals need good preparation and inservice training to effectively deal with the behaviors of an antisocial child. A need for early interventions was also a result of the study. Children as young as age three should be in quality preschool settings. Relationship building is also essential to the success of the children. If interventions do not make a difference by about age eight, antisocial behavior can become chronic disorders for which there is no cure. Advisor: Donald F. Uerlin

Fire Monitoring and Assessment Platform (FireMAP): Acquisition and Preprocessing of UAS Imagery for Further Analysis

Most wildlands in the US have evolved with fire and depend on periodic blazes. The Fire Monitoring and Assessment Platform (FireMAP) seeks to provide the capability to monitor the severity of wildland fires responsively, while maintaining safety and affordability. FireMAP is composed of unmanned aerial systems (UAS) and software to process and geo-analyze imagery. The UAS will perform a post-fire flyover of the affected area and acquire imagery, which will be georeferenced and mosaicked to create a composite image. The software then analyzes the imagery, identifying the burn extent and severity. The objective of image acquisition and preprocessing research is to automate the process of removing camera lense distortion, georeferencing and mosaicking the imagery collected by the UAS. Research is currently being done to maintain accuracy of both the imagery metadata as well as UAS flight log data. FireMAP will utilize both the UAS flight log data and the image metadata for automation of image georeferencing. Automation of preprocessing and georeferencing allows for faster transformation of data collected through imagery into actionable knowledge that can be utilized by FireMAP users

Analysis of Retinal Structure and Processing in Visual Snow Syndrome

Visual snow (VS) is a rare but distressing phenomenon of persistent granular or pixelated visual distortions. The current understanding of VS pathophysiology is limited. We sought to investigate whether retinal structural or electrophysiological abnormalities were present in patients with VS

Classification of species attributes for Pacific Northwest freshwater fishes

Fish assemblages integrate physical and chemical habitat conditions and are used to evaluate the condition of water resources in the Pacific Northwest. To facilitate such evaluations, we classified each of the 132 freshwater fish species known to occur in the Pacific Northwest (Idaho, Oregon, Washington) by its origin, overall pollution tolerance, adult habitat, adult feeding, and water temperature preference. Recommendations from regional fishery experts, published literature, and the aggregate experience of the authors were used to classify species. The attribute classifications were responsive to human disturbance of aquatic habitats when applied to fish assemblages sampled from throughout the region. Our attribute classification of fish species promotes use of fish assemblages to evaluate water resource conditions regionally and fosters greater acceptance of biological measures of water resource qualit
