- Among such species, patch occupancy depends on the presence of a sufficiently sized single patch of habitat (i.e., scale dependence) to contain a territory (Keller 1986; Hinsley et al. 1996; Lindenmayer et al. 1999; Beier et al. 2002).

Oct 10, 2023 · Introduction. The habitat amount hypothesis (HAH) posits that within a local landscape, species richness in a given patch type, termed the “habitat patch”, is simply a function of the total habitat amount in the landscape, regardless of the sizes of the individual habitat patches in that landscape (Fahrig 2013 ).
Population dynamics within a patch were simplified to the point where only presence and absence were considered. Each patch in his model is either populated or not. Let N be the fraction of patches occupied at a given time. During a time dt, each occupied patch can become unoccupied with an extinction probability edt.
Abstract. Patch occupancy surveys are commonly used to parameterize metapopulation models. If isolation predicts patch occupancy, this is generally attributed to a balance between distance‐dependent recolonization and spatially independent extinctions.

Stochastic patch occupancy models (SPOMs) are a type of spatial population simulation. They are arguably well-suited to guide conservation in human-altered landscapes, but their appropriateness for a wide range of species and landscape types has often been questioned.
Nov 1, 2014 · Patch occupancy models are extremely important and popular tools for understanding the dynamics, and predicting the persistence, of spatially structured populations.
