Research interests

Brett Dickson's research and professional interests thread through a wide range of disciplines, including conservation biology and planning, wildlife and landscape ecology, and contemporary statistical modeling and inferential approaches. Much of his work is focused on understanding and estimating animal-habitat relationships, landscape connectivity, the impacts of land use and climate change, or disturbance processes, such as fire and non-native species invasion, in forested and arid ecosystems across North America. As co-Director of the Lab of Landscape Ecology and Conservation Biology at NAU, he seeks to integrate cutting-edge technical approaches to research with graduate student and post-doctoral training, as well as internships and other educational experiences, which are grounded in applied conservation. Dickson is also president of and chief scientist for Conservation Science Partners, Inc., a non-profit institution established to meet the research and analytic needs of conservation-oriented projects and professionals across multiple sectors of society. Typically, his projects, research staff, and students collectively bridge the efforts of these organizations.
