Modeling the Effect of Traffic Calming on Local Animal Population Persistence

摘要: A steady growth in traffic volumes industrialized countries with dense human populations is expected, especially on minor roads. As a consequence, the fragmentation of wildlife will increase dramatically. In human-dominated landscapes, typically roads occur high densities, and animals encounter them frequently. Traffic calming new approach to mitigate negative impacts by reducing speeds at regional scale. This leads distinction between low as being part traffic-calmed area, whereas bundled are located around this area. Within can be decreased substantially; predicted decrease disturbance mortality risk for animals. Thus far, data effects population persistence remain scarce. Using metapopulation theory, we derived model estimate thresholds size areas that may allow persistent populations.
