A simple landscape-scale test of a spatially explicit population model: patch occupancy in fragmented south-eastern Australian forests
The results of a landscape-scale test of ALEX, a widely used metapopulation model for Population Viability Analysis (PVA), are described. ALEX was used to predict patch occupancy by the laughing kookkaburra and the sacred kingfisher in patches of eucalypt forest in south-eastern Australia. These predictions were compared to field surveys to determine the accuracy of the model. Predictions also ...
متن کاملA demographic, spatially explicit patch occupancy model of metapopulation dynamics and persistence
Patch occupancy models are extremely important and popular tools for understanding the dynamics, and predicting the persistence, of spatially structured populations. Typically this endeavor is facilitated either by models from classic metapopulation theory focused on spatially explicit, dispersal-driven colonization–extinction dynamics and generally assuming perfect detection, or by more recent...
متن کاملAnthropogenic landscape change promotes asymmetric dispersal and limits regional patch occupancy in a spatially structured bird population.
1. Local extinctions in habitat patches and asymmetric dispersal between patches are key processes structuring animal populations in heterogeneous environments. Effective landscape conservation requires an understanding of how habitat loss and fragmentation influence demographic processes within populations and movement between populations. 2. We used patch occupancy surveys and molecular data ...
متن کاملSELES: A Spatially Explicit Landscape Event Simulator
Landscape structure results from complex interactions between geomorphology, climate, disturbance and succession. SELES is a tool for building spatially explicit simulations to model the role of disturbance in creating and maintaining landscape structure. Models built with SELES are raster-based, semi-Markov, whole landscape models (sensu Baker 1989) which use probabilistic disturbance spread. ...
متن کاملSpatially-explicit Modeling of Siberian Boreal Forests
Circumpolar boreal forests contain one half of the terrestrial carbon stores, and have been shown to be susceptible to climate change. As climate regimes shift, the total biomass and species composition may change in ways that may promote further warming on the regional level through atmosphere-vegetation feedbacks. The purpose of this project is to develop a spatially explicit model for simula...
