Abundance patterns in multi-species communities exposed to habitat destruction.
Habitat destruction resulting from human activity is a serious threat to biodiversity. The model developed by Tilman et al. [Tilman, D., May, R.M., Lehman, C.L., Nowak, M.A., 1994. Habitat destruction and the extinction debt. Nature 371, 65-66] has become an important tool for analyzing persistence of species in habitats under destruction. However, most analysis and applications of this model h...
متن کاملHabitat Modeling for Biodiversity Conservation
Habitat models address only 1 component of biodiversity but can be useful in addressing and managing single or multiple species and ecosystem functions, for projecting disturbance regimes, and in supporting decisions. I review categories and examples of habitat models, their utility for biodiversity conservation, and their roles in making conservation decisions. I suggest the use of influence d...
متن کاملHabitat destruction, environmental catastrophes, and metapopulation extinction.
The extinction process of fragmented populations, characterized by a small number of conspecifics inhabiting each patch, is heavily affected by natural and human disturbance. To evaluate the risk of extinction we consider a network of identical patches connected by passive or active dispersal and hosting a finite, discrete number of individuals. We discuss three types of disturbance affecting t...
متن کاملIndirect effect of habitat destruction on ecosystems
Habitat destruction is one of the primary causes of species extinction in recent history. Even if the destruction is restricted to a local and small area, its accumulation increases the risk of extinction. To study local destruction of habitat, we present a lattice ecosystem composed of prey (X) and predator (Y). This system corresponds to a lattice version of the Lotka-Volterra model, where in...
متن کاملHabitat destruction: death by a thousand cuts
Humankind has dramatically transformed much of the Earth’s surface and its natural ecosystems. This process is not new—it has been ongoing for millennia—but it has accelerated sharply over the last two centuries, and especially in the last several decades. Today, the loss and degradation of natural habitats can be likened to a war of attrition. Many natural ecosystems are being progressively ra...
