Survivability of a metapopulation under local extinctions.

A metapopulation structure in landscape ecology comprises a group of interacting spatially separated subpopulations or patches of the same species that may experience several local extinctions. This makes the investigation of survivability (in the form of global oscillation) of a metapopulation on top of diverse dispersal topologies extremely crucial. However, among various dispersal topologies...

Host diet aects extinctions and colonizations in a parasitoid metapopulation

1. In the AÊ land islands of SW Finland, the parasitoid Cotesia melitaearum (Wilkonson) is a specialist on the Glanville fritillary butter ̄y, Melitaea cinxia (L.), which uses two host plants, Plantago lanceolata (L.) and Veronica spicata (L.). 2. Extensive survey data on the butter ̄y and parasitoid populations collected in 1994±97 were used to examine possible associations of parasitoid coloniz...

A Metapopulation Model with Local Competitions

A metapopulation model with explicit local dynamics is studied. Unlike many patch-based metapopulation models which assume that the local population within each patch is at its equilibrium, our model incorporates population changes in local patches that interact with metapopulation dynamics. The model keeps track of the fractions of patches that have species 1 only, species 2 only, or both spec...

Optimal Coding Subgraph Selection under Survivability Constraint

Nowadays communication networks have become an essential and inevitable part of human life. Hence, there is an ever-increasing need for expanding bandwidth, decreasing delay and data transfer costs. These needs necessitate the efficient use of network facilities. Network coding is a new paradigm that allows the intermediate nodes in a network to create new packets by combining the packets recei...
