Land use change is certainly the most important factor that affects the conservation of natural ecosystems, resulting the conversion of natural lands such as forests and pastures into agricultural, industrial and urban areas. Despite numerous studies investigating landscape patterns due to land use change, the driving forces of landscape change has been less studied in Iran. In this study, Arti...
The sensitivity of landscape metrics to the scale effect is one of the most challenging issues in landscape ecology and quantification of land use spatial patterns. In this study, fractal dimension was employed to assess the effect of scale on the sensitivity of landscape metric in the north of Iran (around Sari) as the case study. Land use/ cover maps were derived from Landsat-8 (OLI sensor) i...
In this paper, we propose a quantitative indicator for measuring and ranking real estate from the perspective of the surrounding landscape by integrating the building information model (BIM) and the three-dimensional geospatial information system (3DGIS) based on the AHP method. The landscape is one of the qualitative variables which it's measuring and quantifying is a complex task. In previous...
Dragonflies are good indicators of environmental health and biodiversity. Most studies addressing dragonfly ecology have focused on the importance of aquatic habitats, while the value of surrounding terrestrial habitats has often been overlooked. However, species associated with temporary aquatic habitats must persist in terrestrial environments for long periods. Little is known about the impor...
Over 450 pre-Columbian (pre-AD 1492) geometric ditched enclosures ("geoglyphs") occupy ∼13,000 km2 of Acre state, Brazil, representing a key discovery of Amazonian archaeology. These huge earthworks were concealed for centuries under terra firme (upland interfluvial) rainforest, directly challenging the "pristine" status of this ecosystem and its perceived vulnerability to human impacts. We rec...
Design and synthesis of porous solids employing both reversible coordination chemistry and reversible covalent bond formation is described. The combination of two different linkage modes in a single material presents a link between two distinct classes of porous materials as exemplified by metal-organic frameworks (MOFs) and covalent organic frameworks (COFs). This strategy, in addition to bein...
Recent investigations have shown how chance, long-range dispersal events can allow tree populations to migrate rapidly in response to changes in climate. However, this apparent solution to Reid's paradox applies solely within the context of single species models, while the rapid migration rates seen in pollen records occurred within multispecies communities. Ecologists are therefore presented w...
Hostels are low-cost, short-term accommodations for travelers of all ages. Visitors pay for either a public or a private room. Prices vary based on style, location, and amenities but overall are very affordable. Hostels are the most common choice of accommodation for travelers; there are membership deals and discounts for frequent users. For more information, visit STA Travel [1]. Things to Con...
