Population persistence in fragmented landscapes
Many ecologists believe that fragmenting habitats into discontinuous patches disrupts the reproduction, survivorship and movement of animals. It has seldom, however, been possible to measure all these processes in one study. Recent work by Lesley and Michael Brooker on an Australian songbird, the blue-breasted fairy wren Malurus pulcherrimus, has achieved this elusive goal. Their new paper in W...
متن کاملPersistence of a population in randomly fragmented landscapes
In a fragmented world, species survival depends on dispersal, as local populations at high risk of extinction could be rescued by immigration from neighboring populations. This intuition forms the core of metapopulation models: even though local populations occupying suitable habitat patches might undergo extinction, persistence can be achieved at the metapopulation level as long as individuals...
متن کاملMetapopulation Persistence in Random Fragmented Landscapes
Habitat destruction and land use change are making the world in which natural populations live increasingly fragmented, often leading to local extinctions. Although local populations might undergo extinction, a metapopulation may still be viable as long as patches of suitable habitat are connected by dispersal, so that empty patches can be recolonized. Thus far, metapopulations models have eith...

متن کاملA persistence landscapes toolbox for topological statistics
Topological data analysis provides a multiscale description of the geometry and topology of quantitative data. The persistence landscape is a topological summary that can be easily combined with tools from statistics and machine learning. We give efficient algorithms for calculating persistence landscapes, their averages, and distances between such averages. We discuss an implementation of thes...
