Abstract
From introduction: "I agree with Rothley and others that these cracks are potentially problematic for landscape connectivity analyses, and I join them in cautioning conservation scientists to create valid models when generating spatial data inputs to cost-weighted analyses. However, I disagree as to the cause and the ubiquity of these cracks. I also provide a few additional procedures that will eliminate potential problems resulting from the misspecification of resistance surfaces and minimize possible additional artifacts arising from any correction processes. This note is intended to continue the important discussion about developing useful methods for computing functional landscape connectivity."
