This dataset depicts Lynx (Lynx canadensis) habitat in the Northern
Appalachians predicted using the spatially explicit population model
PATCH under the population cycling across the region plus trapping plus
climate change scenario (FC2; Carrol 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 cover and annual snowfall. Demographic
parameters were obtained from the literature and from calibration of the
model. Several hundred individual model simulations were used to create
this dataset. Lynx population cycling with respect to snowshoe hare
(Lepus americanus) density was addressed by scaling habitat quality
values from the static habitat model to lynx demographic rates at
different points in the population cycle. Three scenarios were created:
no cycling, cycling only in the core area (Gaspe population), and
cycling throughout the region. The influence of trapping was addressed
by incorporating a 10% decrease in survival rate in the Gaspe and Quebec
areas. The influence of climate change was addressed by incorporating
predicted snowfall for 2055 from IPCC Scenario A2 into the static
habitat model.
