Road and railway networks are pervasive elements of all environments, which have expanded intensively over the last century in all European countries. These transportation infrastructures have major impacts on the surrounding landscape, representing a threat to biodiversity. Roadsides and railways may function as corridors for dispersal of alien species in fragmented landscapes. However, only f...

Knowledge of dispersal-related gene flow is important for addressing many basic and applied questions in ecology and evolution. We used landscape genetics to understand the recovery of a recently expanded population of fishers (Martes pennanti) in Ontario, Canada. An important focus of landscape genetics is modelling the effects of landscape features on gene flow. Most often resistance surfaces...

Private road associations (PRAs) manage two thirds of the road network in Sweden. They manage the roads at less cost and with better results than the Government road agencies. In fact, the PRAs perform so well that some urban municipalities request the associations to manage the municipal roads which connect to the private roads. There are also PRAs that are responsible for ferry services, for ...

Wireless technologies are making the development of new applications and services in vehicular environments possible since they enable mobile communication between vehicles (V2V), as well as communication between vehicles and infrastructure nodes (V2I). Usually, V2V communications are dedicated to the transmission of small messages mainly focused on improving traffic safety. Instead, V2I commun...

1 Geographic information systems (GIS) are widely used for mapping wildlife movement 2 patterns, and observed wildlife locations are surrogates for inferring on wildlife 3 movement and habitat selection. We present a new approach to mapping areas where 4 wildlife exhibit sustained use, which we term slow movement areas (SMAs). Nested 5 within the habitat selection concepts of home range and cor...

The quality aspects of OpenStreetMap (OSM), as the global representation of crowd-sourced mapping, have always been of priomary concern to academics. While the methodologies for checking its quality against the national maps have been implemented by a number of studies, there are minimal works on how to practically improve the quality of OSM towards being an authoritative map source. This paper...

People desire luxury products because they are highly valued by society, among other reasons, but little is known about how wearing luxury products influences consumers’ selfidentity and behavior. This research demonstrates that wearing luxury products can lead consumers to engage in behaviors that are highly valued by society. Study participants who wear or simply imagine themselves wearing lu...
