Dynamic occupancy modeling of temperate marine fish in area-based closures
Jay Calvert, Chris McGonigle, Suresh Sethi, Bradley Harris, Rory Quinn, Jon Grabowski
2018, Ecology and Evolution (8) 10192-10205
Species distribution models (SDMs) are commonly used to model the spatial structure of species in the marine environment, however, most fail to account for detectability of the target species. This can result in underestimates of occupancy, where nondetection is conflated with absence. The site occupancy model (SOM) overcomes this failure...
