This dataset depicts Lynx (Lynx canadensis) habitat in the Northern Appalachians predicted using the spatially explicit population model PATCH under the population cycling only in Gaspe (core area) plus trapping plus climate change scenario (FB2; Carroll 2007). This dataset represents one of several scenarios testing the interacting effects of population cycling, trapping, territory size, and climate change on lynx populations. Static habitat suitability models for lynx were fed through PATCH to predict source and sink habitat areas across the landscape. The static models for lynx were created based on a logistic regression model of reported lynx locations against the proportion of the landscape in deciduous forest...

This dataset shows simulated fisher territory occupancy for a study area the southern Sierra Nevada range from the Baseline Fire Regime plus Moderate Intensity Treatment over 8% of the treatable area scenario (Scheller and others 2008). Simulations were conducted using the spatially dynamic population model PATCH coupled to the forest succession and disturbance model LANDIS-II. Fisher occupancy is represented as the average number of females per 860 hectare hexagon. Habitat quality was derived from LANDIS-II simulated vegetation dynamics and was used to drive spatially-explicit demographic dynamics in PATCH. The baseline fire regime is derived from the previous 20 years of fire data. The extreme fire regime is a...

Habitat modeling offers an approach to understanding some management problems of desert tortoises (Gopherus agassizii) and to focusing new research efforts. Modeling can provide (1) a method to organize existing information, (2) a means to identify whether physical habitat or some factor outside the scope of the habitat model is limiting populations, (3) a method to integrate habitat into resource development planning, and (4) a mechanism for focusing research on missing species-habitat information. Published in Herpetologica, volume 42, issue 1, on pages 134 - 138, in 1986.
