Abstract Ecological Risk Assessment faces the challenge of determining impact invasive species on biodiversity conservation. Although many statistical methods have emerged in recent years order to model evolution spatio-temporal distribution species, notion extent occurrence, formally defined by International Union for Conservation Nature, has not been properly handled. In this work, a novel an...

Rapid extensive magmatism may have a profound effect on global climate by liberating and releasing greenhouse gases to the atmosphere through contact metamorphism of lithologically heterogeneous host rocks degassing magma associated lava flows. The high Arctic Archipelago Svalbard offers accessible, superbly exposed outcrops revealing Early Cretaceous with High Large Igneous Province (HALIP). I...

Inversion-asymmetric stacks of metallic magnetic layers have often been exploited to control the chiral noncollinear ordering their moments. Here, authors investigate interfacial aspects Dzyaloshinskii-Moriya interaction, giving rise this ordering, and quantify its contributions within a couple atomic layers. This observation is further supported by first-principles calculations. The confirmati...

development of remote sensing (rs) and gis techniques and that of landscape metrics in the late 1980s have caused to introduce a new dimension in the landscape ecology arena (the relationship between spatial patterns and ecological processes). however, scale dependence of some of landscape metrics and rs systems of different spatial resolution has resulted in particular attention into selection...

The extent of poverty, inequality and environmental differences patterns in large metropolises are the results of a dual economy with free market capitalism rule in these cities. Urban spatial structure expansion and incoherent, irrational focus on different parts of the city and its facilities and services, economic development, social inequality in them. Urban environments, complex systems wi...
