Metrics and Models for Quantifying Ecological Resilience at Landscape Scales

Soil Landscape Models at Different Scales Portrayed

quantifying the impacts of roads on isfahan landscape pattern using gradient analysis and landscape metrics methods

quantifying urban landscape is fundamental for monitoring and assessing ecological and socioeconomic consequences of urbanization. expansion of roads is a significant factor driving urban landscape change. the aim of this research is quantifying impacts of roads on isfahan city landscape. to achieve this aim, land use map of isfahan was created in 6 classes: urban, green spaces, agricultural, b...

Quantifying spatial heterogeneity at the landscape scale using variogram models

The monitoring of earth surface dynamic processes at a global scale requires high temporal frequency remote sensing observations which are provided up to now by moderate spatial resolution sensors. However, the spatial heterogeneity within the moderate spatial resolution pixel biases non-linear estimation processes of land surface variables from remote sensing data. To limit its influence on th...

Habitat requirements and ecological niche of two cryptic amphipod species at landscape and local scales

Cryptic species are phylogenetically diverged taxa that are morphologically indistinguishable and may differ in their ecological and behavioral requirements. This may have important implications for ecosystem services and conservation of biodiversity. We investigated whether two ecologically important cryptic species of the freshwater amphipod Gammarus fossarum (types A and B) are associated wi...

Building a Comprehensive Conceptual Framework for Power Systems Resilience Metrics

Recently, the frequency and severity of natural and man-made disasters (extreme events), which have a high-impact low-frequency (HILF) property, are increased. These disasters can lead to extensive outages, damages, and costs in electric power systems. A power system must be built with “resilience” against disasters, which means its ability to withstand disasters efficiently while ensuring the ...
