Simulating demography, genetics, and spatially explicit processes to inform reintroduction of a threatened char
2019
Ecosphere
Preserved Fulltext
Simulation-based approaches are a promising technique for evaluating the independent and combined effects of these factors on the outcome of various reintroduction and associated management actions. ...
Although the importance of these factors in the success of reintroductions is well-accepted, they are typically evaluated independently, which can miss important interactions. ...
To this end, we evaluated the role of spatial, demographic, and genetic factors in the success of reintroduction of bull trout to the lower Pend Oreille River and its tributaries. ...
