Hikers and livestock using mountain trails damage native vegetation act as seed vectors, thus favouring the spread of non-native plants. We evaluated effect abundance on success plants in arid central Andes Argentina. surveyed six trails, covering elevations between 2400 3570 m a.s.l. recorded transects distributed along elevational gradient spanning distances up to 22 from trail. assessed how ...

A large recreation value may be expected for a long-distance walking track which allows for hiking and camping in a tropical rainforest environment. When such a resource is new, sufficient data are not available for a primary study. A practical way to obtain a value estimate is by employing benefit transfer procedures. Using a travel cost analysis for the Thorsborne Trail as the transfer source...

Research settings include a full range of encounters with nature -extended wilderness excursions, hiking in open space, strolling through a city park, gardening, tending a small plot of urban grass or a vacant city lot with its attendant ecosystem, and even watching nature scenes on TV. While different psychological approaches (evolutionary, behavioral, cognitive, psychodynamic, systems, humani...

A 2 year old fully immunized male with no personal history of chicken pox presented to the emergency department with a chief complaint of a rash for one week after returning from a hiking trip in a remote island in Canada. After initially being diagnosed with contact dermatitis, a diagnosis of herpes zoster was made by confirmatory viral polymerase chain reaction testing. The purpose of this ca...

The Dual Contouring algorithm (DC) is a grid-based process used to generate surface meshes from volumetric data. The advantage of DC is that it can reproduce sharp features by inserting vertices anywhere inside the grid cube, as opposed to the Marching Cubes (MC) algorithm that can insert vertices only on the grid edges. However, DC is unable to guarantee 2-manifold and watertight meshes due to...
