A continental-scale integrated population model for the American kestrel A continental-scale integrated population model for the American kestrel
American kestrels have been declining in North America for several decades for unknown causes despite extensive research. We examined long-term population trends at a continental scale to eliminate statistical artifacts of immigration and immigration, and were able to identify trends in specific vital rates that can better inform future management actions. Included in this repository is...
Alligator snapping turtle population simulation model developed in support of the Species Status Assessment Alligator snapping turtle population simulation model developed in support of the Species Status Assessment
This software release contains six R scripts that comprise a population viability analysis for the alligator snapping turtle (Macrochelys temminckii). To predict numbers of M. temminckii in the future, we constructed a female-only, stage-structured matrix projection model. We incorporated multiple types of uncertainty into the simulation model, including parametric uncertainty and...
Golden Eagle Survival in the Great Plains, Nestlings, with Territory and Time Random Effects - Supplemental Code Golden Eagle Survival in the Great Plains, Nestlings, with Territory and Time Random Effects - Supplemental Code
R code for modeling survival of nestling and fledgling golden eagles. It is supplemental material for a manuscript submitted to Journal of Raptor Research.
American alligator growth simulation and integrated population model American alligator growth simulation and integrated population model
The software consists of three scripts to be run in the R statistical program: 1) Alligator growth simulation; 2) alligator integrated population model file; and 3) data visualization script. Script #1 produces growth transition probabilities that are used in script #2. The second script uses the outputs from #1 as well as other data files to run an integrated population model. The last...
