Full Course Description

Space-use decisions made by animals in heterogeneous environments can reflect a variety of important processes, including the acquisition and investment of energy, avoidance of mortality from predation or other sources, intra- and interspecific competition, and interactions with both natural and anthropogenic features of the landscape. Consequently, quantifying patterns of resource selection by animals can provide key insights into relationships among the environment, individual fitness, and population dynamics that are critical for making effective management and conservation decisions. Although powerful model-based approaches to quantifying resource selection have been developed in recent years, many managers and researchers continue to use outdated techniques that provide limited insight into complex wildlife-habitat relationships. The objective of this course is to provide participants with the skills and confidence necessary to proceed from a raw dataset of animal locations and habitat characteristics to a final resource selection function using modern modeling techniques. Course structure will consist of lecture modules in the mornings (roughly 30% of the course) focused on key elements of the background and theory of resource selection analysis, and hands-on computer labs in the afternoons (roughly 70% of the course). Some previous experience with ArcGIS and/or R statistical software will be helpful.

Course Topics

  • Lecture: Introduction to resource selection analysis
    • Central definitions and concepts (use, availability, selection, preference, etc.)
    • Spatial and temporal scale (1st through 4th order selection and the importance of daily and seasonal patterns of selection)
    • Sampling and study design (the various sampling schemes and units typically associated with resource selection studies)
    • Categorical data and selection ratios (2D vs. 3D selection ratios, selection ratios as the response variable in a modeling framework)
    • Modeling resource selection (advantages, disadvantages, goals, and steps)
  • Lecture: Logistic regression
    • The logistic model and classic logistic design
    • Difficulties of the classic approach
    • Mixed-effects logistic regression (with a discussion of conditional logistic regression)
  • Hands-on computer lab: Modeling resource selection using mixed-effects logistic regression
  • Lecture: Modeling use as a continuous variable
    • Resource utilization functions (RUFs; Marzluff et al. 2004, Millspaugh et al. 2006)
    • Negative binomial regression (Sawyer et al. 2006, 2007, 2009)
  • Hands-on computer lab: Modeling resource selection using the RUF approach
  • Hands-on computer lab: Modeling resource selection using negative binomial regression
  • Interactive presentation: Mapping predicted probability of use from an RSF across a landscape
  • Interactive presentation: K-fold cross validation

Forest Ecology/Management course – June 25-29, Corvallis, OR

This course on forest ecology will provide biologists and land managers with basic forest ecology and management knowledge and skills. While the course will be taught at Oregon State University, with daily, hands-on site visits to the nearby McDonald Forest, this will NOT be strictly a west-side forest class. The basics of forest ecology that are part of this course will apply to many forest types, and between case studies and opportunities for student engagement with specific forest issues they are dealing with, there will be ample opportunity to learn about and discuss application in a wide variety of forest types. Dr. McComb has a long career in researching and teaching forest ecosystems and the application of forest ecology in wildlife habitat management. This is a great opportunity to get hands on with a knowledgeable and excellent instructor! Tuition is waived for NPS employees!
