Unifying deterministic and stochastic ecological dynamics via a landscape-flux approach

A landscape-ecological approach

Framework, concepts, and methods of Environmental Management Planning (EMP) are discussed. A landscape-ecological approach was taken to integrate the environmental indices. EMP focuses on regional factors natural, social, amenity related and becomes more sensitive as the scale of study increases. The processes of EMP include a vertical aspect, dealing with pollution, conservation, and amenities...

Metapopulation dynamics in a complex ecological landscape.

We propose a general model to study the interplay between spatial dispersal and environment spatiotemporal fluctuations in metapopulation dynamics. An ecological landscape of favorable patches is generated like a Lévy dust, which allows to build a range of patterns, from dispersed to clustered ones. Locally, the dynamics is driven by a canonical model for the time evolution of the population de...

Integration assessment of Protected Rangeland habitats using landscape ecological approach

The management of areas with landscape ecological approach helps us to have more integrated of considering completely management and also keep the area’s values. Lar National Park and Varjin Protected Area are the most important areas of their biodiversity and wildlife habitats. The aim of this study was quantification of fragmentation in Lar National Park and Varjin Protected Area and to compa...

Field dynamics and tunneling in a flux landscape

We investigate field dynamics and tunneling between metastable minima in a landscape of type IIB flux compactifications, utilizing monodromies of the complex structure moduli space to continuously connect flux vacua. After describing the generic features of a flux-induced potential for the complex structure and type IIB axiodilaton, we specialize to the mirror quintic Calabi-Yau to obtain an ex...
