Determining how widespread human-induced changes such as habitat loss, landscape fragmentation, and climate instability affect populations, communities, and ecosystems is one of the most pressing environmental challenges. Critical to this challenge is understanding how these changes are affecting the movement abilities and dispersal trajectories of organisms and what role conservation planning ...

In order to prevent the adverse effects of rapid urbanization and construction on urban landscape, protection planning hydrological network systems with open green spaces is a contemporary issue for cities. Within scope ensuring sustainability water resources spaces, it necessary protect natural corridors sustainable environment, store rainwater, feed qualities groundwater, create permeable sur...

In the recent European debt crisis, internal migration flows in the euro area reacted strongly to diverging labor market conditions. This experience points towards the prominent role of short-term business cycle migration in the euro area and the consequent need to understand the motives behind it. We start by an empirical investigation of the business cycle in 59 bilateral migration corridors ...

Riparian corridors and fencerows are hypothesized to increase the persistence of forest animals in fragmented landscapes by facilitating movement among suitable habitat patches. This function may be critically important for forest birds, which have declined dramatically in fragmented habitats. Unfortunately, direct evidence of corridor use has been difficult to collect at landscape scales and t...

The global shipping industry has been contributing more than four-fifths of the volume goods transported internationally. However, is facing pressure from strict policies on combating climate change International Maritime Organization (IMO). Seaports are an essential component and also having to their development strategies be sustainable smarter. concept a green port was born as inevitable par...

The dramatic sea ice loss makes trans-Arctic navigation possible. However, navigability assessments at high temporal resolution are still very limited. To bridge this gap, daily concentration and thickness from CMIP6 projections applied to evaluate the future potential of Arctic shipping under multiple climate scenarios. September navigable area will continue increase through 2050s for open-wat...

BACKGROUND Reliable predictions of regional-scale population connectivity are needed to prioritize conservation actions. However, there have been few examples of regional connectivity models that are empirically derived and validated. The central goals of this paper were to (1) evaluate the effectiveness of factorial least cost path corridor mapping on an empirical resistance surface in reflect...

Measuring the dispersal of wildlife through landscapes is notoriously difficult. Recently, the categorical least cost path algorithm that integrates population genetic data with species distribution models has been applied to reveal population connectivity. In this study, we use this method to identify the possible dispersal corridors of five plant species (Castanopsis tibetana, Schima superba,...

In room–corridor building geometry, the corridor smoke temperature is of great importance to fire protection engineering as indoor fires occur. Theoretical analysis and a set of reduced-scale model experiments were performed, and a virtual fire model was proposed, to investigate the correlations between the maximum smoke temperature in corridors and the smoke temperature in rooms. The results s...
