Modeling the spatial and temporal dynamics of the amber-marked birch leaf miner infestation in Anchorage, Alaska
Since 1998, the invasive insect amber-marked birch leaf miner (Profenusa thomsoni Konow.) has been an issue for the birch trees in Alaska's Anchorage Bowl. P. thomsoni is native to Europe and an invasive defoliator of birch trees; its impacts are considered aesthetically unpleasing to Anchorage residents. In this study, a spatial and temporal model was constructed using a cellular automata (CA) method. Employing the statistical program R (R Development Core Team 2008), coupled with a custom library called RandomFields (Schlather 2012) and linear regression techniques, a CA model was created. ...
