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...

in this paper, we are going to investigate the growth of the iranian maritime transport with a focus mainly on the north - south transit corridor, review of dry ports in order to support the iranian container terminals at the south ports in order to increase the volume of container storages at the terminals. for the purpose of assessing the outcome of port operational management, the balanced s...

A transport corridor is a (generally linear) tract of land in which at least one main line is provided for transport, whether it is a road, rail or canal facility. In this paper under transport corridor we will understand a road which connects two geographical points. The need of research and analysis of the transport corridors is mainly connected with wish to locate bottlenecks of the corridor...

This note revisits the role of migrant social networks as determinants of bilateral-migration flows. We do so using a new database that covers about 190 world countries and features more accurate estimates of bilateral flows than those employed so far. Our battery of gravitymodel exercises show that the impact of social networks is consistent and significant over different specifications, and i...

According to ICES, the International Council for the Exploration of the Sea, populations of coastal cod (CC) in Norway north of 628N have been declining since 1994. The estimates are based on analytical assessment in which the most recent estimates are tuned with survey information. We evaluate the quality of bottom-trawl surveys conducted in four North Norwegian fjords during autumn of the yea...

A s wildlands give way to an expanding human footprint, scientists and land managers have struggled to develop land conservation strategies that protect biodiversity. A favored strategy is to connect large habitat areas with landscape corridors (1–3). Yet, the scientific question remains: Do corridors actually work to promote dispersal and conserve biodiversity? In this issue of PNAS, Gillies a...
