While a transitway can be built as an access-controlled, two-way rapid transit facility outside the Central Business District (CBD), in the CBD, initially, the Bus Rapid Transit (BRT) service has to be based on exclusive bus lanes due to right-of-way, monetary, and other constraints. The strategy of providing Bus Rapid Transit on exclusive bus lanes in urban corridors is receiving policy attent...
Least-cost models for focal species are widely used to design wildlife corridors. To evaluate the least-cost modeling approach used to develop 15 linkage designs in southern California, USA, we assessed robustness of the largest and least constrained linkage. Species experts parameterized models for eight species with weights for four habitat factors (land cover, topographic position, elevation...
The concentration of animals in hedgerows also attracts predators from the surroundings 43’ (Fig. 6.10), just as hunters are attracted to wooded strips.299 Where large woods are scarce, certain owls and other predators require two or more smaller woods for their home range. So in a corridor connecting the woods, not much escapes the eyes and silent wing-beat of an owl. Nevertheless, compared wi...
Editorial Corridors and Towers When C P Snow wrote "The Corridors of Power" he sought to demonstrate the inner workings of the political process in Whitehall. Now that we are coming towards the end of the useful life of the building known as the "RVH corridor" it is time to consider some of the inner workings of our own profession. Wards 1-20 in the Royal Victoria Hospital represent only a smal...
ABSTRACT The destruction of the ecological system caused by urban expansion has led to environmental deterioration, cities have become increasingly vulnerable. In this study, six districts and counties along Yellow River in Zhengzhou were selected as study area. First, green infrastructure elements extracted morphological spatial pattern analysis. Then, outside areas, we used connectivity analy...
Habitat fragmentation leads to isolation and reduce habitat areas, in addition to a series of negative effects on natural populations, affecting richness, abundance and distribution of animal species. In such a context, habitat corridors serve as an alternative for connectivity in fragmented landscapes, minimizing the effects of structural isolation of different habitat areas. This study evalua...
The behavior of prey individuals is influenced by a variety of factors including, but not limited to, habitat configuration, risk of predation, and availability of resources, and these habitat-dependent factors may have interactive effects. We studied the responses of mice to an increase in perceived predation risk in a patchy environment to understand how habitat corridors might affect interac...
The purpose of this paper is to compare the biofidelity rating schemes of ISO/TR9790 and the NHTSA Bio Rank System. This paper describes the development of new impact response corridors being proposed for ISO/TR9790 from the results of a recent series of side-impact sled tests. The response data were analyzed by methods consistent with ISO/TR9790, including normalization by impulse-momentum ana...
Climate change is a threat to biodiversity, and adaptation measures should be considered in biodiversity conservation planning. Protected areas (PA) are expected to be impacted by climate change and improving their connectivity with biological corridors (BC) has been proposed as a potential adaptation measure, although assessing its effectiveness remains a challenge. In Mesoamerica, efforts to ...
Abstract Management of animal populations requires spatially explicit knowledge movement corridors, such as those used during seasonal migrations. Global Positioning System (GPS) tracking data allow for mapping corridors from directly observed movements, but are absent many populations. We developed a novel statistical corridor modelling approach that predicts cost‐distance models fit to migrat...
