Mar Cabeza Department of Ecology and Systematics, University of Helsinki, PO Box 65 (Viikinkaari 1), Helsinki, Finland E-mail: [email protected] Abstract Quantitative methods for the design of reserve networks often select over-dispersed reserves, and consequently a number of species extinctions can be expected in such reserves, especially if unprotected surrounding habitat is lost. A novel...

Recent research has shown that landscape-level changes, namely habitat loss and fragmentation, can play an important role in determining the distribution of species across a variety of ecological systems. However, the influence of these large-scale factors in relation to small-scale factors, such as local vegetation structure or composition, is poorly understood. We used Bachman’s Sparrow (Peuc...

Transients in ecology are extremely important since they determine how equilibria approached. The debate on the dynamic stability of ecosystems has been largely focused equilibrium states. However, constantly changing due to climate conditions or perturbations driven by crisis anthropogenic actions (habitat destruction, deforestation, defaunation), it is study dynamics can proceed till equilibr...

Forest Isbell,* David Tilman, Stephen Polasky and Michel Loreau Abstract Habitat destruction is driving biodiversity loss in remaining ecosystems, and ecosystem functioning and services often directly depend on biodiversity. Thus, biodiversity loss is likely creating an ecosystem service debt: a gradual loss of biodiversity-dependent benefits that people obtain from remaining fragments of natur...
