Diel Activity
|
Objectives:
1) To develop and refine statistical models appropriate to estimate animal diel activity. 2) Develop a synthetic framework to rethink the diel activity modalities of diurnal, nocturnal, crepuscular, and cathemeral. 3) To better understand how natural and anthropogenic factors influence animal diel activity patterns temporal use, selection, and preference. 4) To evaluate past assumptions that the functional trait of diel activity is fixed and strictly morphologically constrained by investigating plasticity. 5) To estimate fitness consequence of shifting diel activity due to anthropogenic factors. |

Assessing diel period classification for a global set of mammal and anthropogenic factors leading to diel switching
Objective: To develop a resource selection modeling framework to estimate diel patterns (24-hour period) for a global distribution of mammals. This framework will be used to estimate the temporal use, selection, and plasticity of mammal species globally Main Collaborators: Brian Gerber, Mason Fidino, Zach Farris 
Quantifying urbanization effects on the diel activity of mammals
Objective: To evaluate how common urban mammal species change their use and selection of diel periods (day, night, dawn/dusk) based on natural (temperature) and anthropogenic (urbanization) factors across cities throughout the United States. Main Collaborators: Travis Gallo, Mason Fidino, and Brian Gerber

Rethinking habitat occupancy modeling and the role of diel activity in an anthropogenic world (preprint link)
Objective: To develop a multi-state occupancy framework to estimate how animals change their diel patterns (day, night, dawn/dusk) in response to variable environments Main collaborators: Kim Rivera, Brian Gerber, Mason Fidino, Zach Farris
