Invited Seminar at CES on 18 June 2018 at 3:00 pm titled "Models & Field Sampling to Inform Terrestrial Reptile Conservation in the Great Plains of the U.S." by Danny Martin from Colorado State University
Conservation of native wildlife species remains a challenge in the face of continuing changes in climate and available habitats. Reptiles are likely to be particularly susceptible to environmental change due to their reliance on their environment to maintain body temperature and their limited ability to disperse relative to larger vertebrates. In addition, we know relatively little about the environmental requirements of many reptile species, which makes conservation planning difficult. Here, I use historical occurrence records to model species' historical (1900-1977) and contemporary (1986-2012) distributions using four Species Distribution Model approaches. Because these historical records are known to be biased, I then used a probability-based sampling design and five visual encounter survey methods to estimate occupancy while accounting for imperfect detection. I briefly discuss the benefits of this approach to future monitoring of reptile populations.
