goby: Tidewater Goby Data

In StrattonCh/msocc: Package for Fitting and Analyzing Computationally Efficient Multi-scale Occupancy Models

Description

A data set containing detection of tidewater goby DNA in water samples collected at each of 39 sites located along 400 km of coastline in California and Oregon, USA. At each site, water samples were collected to extract the DNA of the tidewater goby (Eucyclogbobius newberryi), a federally endangered fish species living in estuaries, lagoons, and sloughs. Environmental and ecological variables were also measured at each of the 39 sites, and are included in this dataset.
