Population Ecology of the Northern Spotted Owl

Abstract

The mathematical modeling of populations utilizing field-collected demographic data is an important component of lab curricula in a variety of undergraduate biology lab courses. During the global pandemic brought about by the SARS-CoV-2 virus in 2020, we successfully converted an in-person lab on demographic population modeling to a lab that could be run remotely. We used a Google Earth Web Project to simulate a population study of the Northern Spotted Owl. In the simulation, students collected both demographic and mark-recapture data, based on surveying images of Northern Spotted Owls as they navigated four different wildlife transects. After conducting the survey, students used the data to determine population size using the mark-recapture method, derived a life table, calculated the net reproductive rate, and used the information to assess the current management plan for the population studied. Here we outline the lesson and provide materials required to duplicate the lab or to use Google Earth to create a similar simulation centered around a different species in any location around the globe.
