Item Deadly roads for frogs and toads: a spatial study of amphibian road mortalities and culvert locations in Elk Island National Park(2023) Nelms, Michelle; Maraj, Ramona; McConnell, Mary; Hoang, Michelle; Parks Canada; Fedoruk, JohnRoad mortalities involving amphibians and reptiles are an unfortunate consequence of linear disturbances across landscapes. With the expansion of populated areas and the need to access remote locations via vehicle, roads are required, but their impact is greater than just their physical footprint. Mitigation efforts, such as the installation of culverts, are one option of reducing road mortalities among amphibian and reptile populations. Amphibians and reptiles are by far the group with the highest mortality rate due to vehicle impacts. Elk Island National Park, located east of Edmonton, Alberta, offers an excellent opportunity to look at the correlation between road mortality incidences and culvert locations. The main parkway receives hundreds of thousands of vehicle visitors annually, and, with culverts already installed throughout the road network, the analysis of the mortality frequency and location of adjacent culverts should be evident. By examining the spatial relationship between road mortality incidences and culvert access we hope to find a workable solution for amphibian populations. We had strong evidence to support that the mortality rate increased as the distance from the nearest culvert decreased; therefore, mortality rates were strongly related to culvert location.Item Deadly roads for frogs and toads: a spatial study of amphibian road mortalities and culvert locations in Elk Island National Park(2024) Nelms, Michelle; Maraj, Ramona; McConnell, Mary; Hoang, Michelle; Parks Canada; Fedoruk, JohnRoad mortalities involving amphibians and reptiles are an unfortunate consequence of linear disturbances across landscapes.

Each chapter generally includes a statement of learning outcomes, course notes, review exercises, self-assessment quiz, and homework assignment questions. The book is based on instructor course notes for STAT 151 (Introduction to Applied Statistics) at MacEwan University. In December 2015, the online version of STAT 151, including module notes, quizzes, homework assignment questions and marking rubrics, and a lab manual in R Commander was developed, leading to the creation of this textbook. Each homework assignment has two parts; students must complete Part A by hand and Part B with R Commander. Most data sets for the assignment, assignment questions, and quiz questions are adapted from popular introductory statistics textbooks such as Introductory Statistics by Neil Weiss and Intro STATS by Richard D. De Veaux, Paul F. Velleman, David E. Bock, and Paul D. Velleman. The online STAT 151 was completed and offered for the first time in Spring 2018. This open textbook is the revised and enriched version of that online course. The only prerequisite of this book is high school mathematics; most students take STAT 151 in the first year of their post-secondary education. R Commander is taught instead of R/RStudio as the software for the lab component to avoid focusing on the programming component needed for R/R Studio. In a future edition, there are plans to include a lab manual with command lines in R/RStudio. This book introduces one-sided confidence intervals to help students understand the computer output of hypothesis testing in R Commander.
