In a new paper (Johst et al., 2011) led by Karin Johst, we examine trade-offs regarding extinction risk between number, connectivity and turnover of habitat patches of habitat networks. The paper is based on a previous work by (Drechsler & Johst, 2010).
Knowing the trade-offs between these spatio-temporal landscape attributes is crucial for dynamic conservation planning approaches, but also for setting incentives or trading rules in market-based conservation policies such as offsetting, conservation banking, tradable permits or payments that naturally have to deal with the problem of landscape dynamics. Martin Drechsler and I highlight the problems that may arise when neglecting landscape dynamics in offsetting mechanisms in (Hartig & Drechsler, 2009).
