Would you like to use occupancy modeling in your studies of marine mammals? Check out these online courses from the Center for Wildlife Studies! Learn at your own pace over a 3-month period. Introduction to Occupancy Modeling <https://www.centerforwildlifestudies.org/courses/p/occupancy-modeling-intro> Species presence/absence is a fundamental concept used in many areas of ecology, including studies of marine mammal species distributions and monitoring efforts. However, imperfect detection can lead to false absences. Unaccounted for false absences can lead to misleading inferences about patterns and dynamics of species occurrence and the factors that influence them. We will learn methods for accounting for imperfect detection with species detection/non-detection data and also discuss important study design considerations. Exercises are completed using Program PRESENCE and RPresence. Advanced Occupancy Modeling <https://www.centerforwildlifestudies.org/courses/p/occupancymodeling-ii> This course is aimed at participants that have completed the introductory-level course, or have suitable practical experience implementing species occurrence models that account for imperfect detection. In this course, learn the underlying theory of multi-scale, multi-state, species co-occurrence, and community level models and then put your new knowledge into practice. All hands-on exercises will be conducted in R, covering data analysis and presentation of results (plotting results, creating maps, etc.). DATES: September 2 - November 23, 2025 PRICE: Starts at $275 students / $375 professionals (early bird ends August 3) LEARN MORE & REGISTER HERE: https://www.centerforwildlifestudies.org/courses [image: Logo] <https://www.centerforwildlifestudies.org/> *Emily J.
