Degrees:

B.S. Environmental Studies                                       2006      University of Maine at Machias

M.S. Marine and Environmental Biology                   2010      Nicholls State University

Ph.D. Biology                                                              2015      Kansas State University

Research Interests:

Dr. Raynor’s research interests include behavioral ecology, plant-herbivore interactions, the ecology and management of rangelands, and conservation biology. His current research examines interactions among cattle, management strategies, and precipitation.

 

His specific research questions are:

At what scales (temporal and spatial) do forage resources mediate cattle foraging behavior and performance?

What vegetation measurement tools can benefit adaptive rangeland management?

What local and hemispherical meteorological factors can be incorporated into ranch decision-making to benefit year-to-year livestock performance?
