Proteus has had a long-standing relationship with the United States Geological Survey (USGS) Amphibian Research and Monitoring Initiative (ARMI), developing methods to model species occurrence data while accounting for potential 'false absences' in the data (i.e., when the species was present but undetected. These methodological developments are very important to enable reliable conclusions to be made about the patterns and dynamics of species distributions. ARMI have been a prime supporter of the development of occupancy models since 2001 by funding numerous research projects. These methods are now widely used on many different species all around the world. In 2017, our Senior Biometrician Darryl MacKenzie was lead author on the second edition of the book Occupancy Estimation and Modeling, which details many of these techniques.
