Abstract:

Universiti Malaysia Sabah housed a dense secondary forest that served as one of the urban forests and green lungs in Kota Kinabalu of Sabah, and this urban forest was known as UMS Peak. Few formal and informal trails were established within UMS Peak, and their conditions were yet to be properly evaluated since their establishments in 2009. Therefore, a preliminary assessment was required to assess existing conditions of these urban forest trails within UMS Peak. Two identified formal trails (Waterfall Trail and Chancellery Trail) and one informal trail (Kg. E Trail) were selected for rapid vis

Abstract:

Background: Urban trails are a useful resource to promote physical activity. This study identified features of urban trails that correlated with trail use. Methods: Multiuse urban trails were selected in Chicago, Dallas, and Los Angeles. An audit of each trail was completed using the Systematic Pedestrian and Cyclist Environmental Scan for Trails instrument, identifying built environmental features. A self-report of trail use was obtained from trailside residents (N = 331) living within 1 mile of each trail. Univariate and multivariate Poisson regressions controlled for trail time from home an

Abstract:

Most snails and slugs locomote over a layer of mucus and although the resultant mucus trail is expensive to produce, we show that this expense can be reduced by trail following. When tracking over fresh conspecific trails, the marine intertidal snail Littorina littorea (L.) produced only approximately 27% of the mucus laid by marker snails. When tracking over weathered trails, snails adjusted their mucus production to recreate a convex trail profile of similar shape and thickness to the trail as originally laid. Maximum energy saving occurs when following recently laid trails which are little

Understanding meteor trail plasma turbulence is important because turbulent meteor trails are visible as non-specular trails to coherent radars. Turbulence also influences the evolution of specular radar meteor trails; this fac

Creating a routing backbone is a fundamental problem in both biology and engineering. The routing backbone of the trail networks of arboreal turtle ants (Cephalotes goniodontus) connects many nests and food sources using trail pheromone deposited by ants as they walk. Unlike species that forage on the ground, the trail networks of arboreal ants are constrained by the vegetation. We examined what objectives the trail networks meet by comparing the observed ant trail networks with networks of random, hypothetical trail networks in the same surrounding vegetation and with trails optimized for fou

Ants use chemical trails, laid down on the ground, for recruiting congeners and helping them to return to the nest.

These young ants begin to better walk along a trail when being in presence of trail following older congeners. Later on, they can by themselves rather efficiently follow a trail.

The wave length, wave amplitude, and overall form and shape of this modern trail compares favorably to Eocene wave-like trails attributed to nematodes. Consequently, a ceratopogonid larva is believed responsible for at least some of those fossil trails.

Abstract. This paper examines impacts of increased visitation leading to human trampling of vegetation and soil along several trails in Rocky Mountain National Park (RMNP) to understand how abiotic factors and level of use can influence trail conditions. RMNP is one of the most visited national parks in the USA, with 3.3 million visitors in 2012 across 1075 km2 and 571 km of hiking trails. 95 % of the park is designated wilderness, making the balance between preservation and visitor use challenging. This research involves the application of trail condition assessments to 56 km of trails to det

Abstract:

This project investigated the history of the backcountry trail system in Grand Teton National Park (GTNP). In cooperation with GTNP Cultural Resources and the Western Center for Historic Preservation in GTNP, we located records describing the early development of the trail system. Only a few historical records describe or map the exact location of early trails, which prove useful when relocating trails today. The paper trail becomes quite rich, however, in revealing the story behind the practical development of Grand Teton National Park as it joined the National Park Service system.

Abstract:

Soft-surface exercise infrastructure (ie off-road, mountain, and dirt trails) has been a particularly valuable community asset in mountainous, urban municipalities. This off-road, trail infrastructure can encourage individuals to engage in green exercise (ie physical activity done outside while in nature, for example, mountainous trails and near waterways). Green exercise can be helpful for encouraging individuals to participate in exercise who otherwise may not; it is especially helpful for promoting mental well-being and a sense of being connected to the environment.

Abstract:

National Trail is an integral component of the system of natural reserves. China’s study on the creation of National Trail is scattered and lacks theory and policy at present. Here, the theoretical framework, technical procedure, and construction management of National Trail are examined based on the national conditions of China and the building experience of foreign National Trail. A research framework for National Trail is then established. The research framework encompasses a theoretical framework of policy and related theories, a technical process of analyzing National Trail resource manag

Abstract:

Ants use multiple cues for navigating to a food source or nest location. Directional information is derived from pheromone trails or visual landmarks or celestial objects. Some ants use the celestial compass information along with an ‘odometer’ to determine the shortest distance home, a strategy known as path integration. Some trail-following ants utilise visual landmark information whereas few of the solitary-foraging ants rely on both path integration and visual landmark information. However, it is unknown to what degree trail-following ants use path integration and we investigated this in a

The Theory of Planned Behavior (TPB) and the Norm Activation Model (NAM) are often employed to examine behavioral intention, but the perspective and attribute differences of these two models have been largely neglected. This study applies TPB and NAM to analyze and compare the intention of trail tourists to undertake environmentally responsible behavior (ERB), which may directly affect the sustainability of the trail system and the surrounding areas. A survey research approach was employed, and 452 responses were collected from tourists in three national forest trails in China. Beginners and e

The article deals with the analysis of morphological aspects of the forest litter structure on ecological and tourist routes in the mountainous region. The study revealed that the changes in the basic parameters of the forest litter are caused by ground trampling. It was estimated that on trails between 0.5 m and 2 m wide, the stock of forest litter is 1.23-1.5 kg/m², and its capacity is 1.3-1.6 cm. With the supply of fresh foliage on the trails, the L, F and H sub-horizons can be identified there. On trails of 2 to 3 m wide, the stock of forest floor is 0.51-0.91 kg·m², that is almost twice l
