When Adaptive Traffic Control Systems are evaluated their safety benefits are rarely investigated. This ‘lack of interest’ in safety performance may be attributed to two major factors: 1) field assessments of safety improvements are impractical (i.e. time consuming and costly), and 2) methods for obtaining safety metrics from microscopic simulation models are uncommon. While collecting and anal...
Golden jackals are locally common in Bangladesh despite intensive cultivation and high human densities. We studied the relative importance of seasonal flooding, rodent prey-base, and daytime cover on the occurrence of golden jackals in the two major agro-ecosystems in Bangladesh, one with annual monsoon flooding and the other without. Jackals were less common throughout the year where floodwate...
We investigated three main niche components (diet composition, habitat use and diel activity rhythms) to examine how the weasel Mustela nivalis and the stoat M. erminea, both specialised predators of small rodents, could permanently coexist in Belarus. Our research was carried out in temperate forests of Belarus, in two study areas with different environmental conditions: 1) continuous dry-land...
Identification of species from trace samples is now possible through the comparison of diagnostic DNA fragments against reference DNA sequence databases. DNA detection of animals from non-invasive samples, such as predator faeces (scats) that contain traces of DNA from their species of origin, has proved to be a valuable tool for the management of elusive wildlife. However, application of this ...
Noninvasive genetic sampling is an important tool in wildlife ecology and management, typically relying on hair snaring or scat sampling techniques, but hair snaring is labor and cost intensive, and scats yield relatively low quality DNA. New approaches utilizing environmental DNA (eDNA) may provide supplementary, cost-effective tools for noninvasive genetic sampling. We tested whether eDNA fro...
The provision of accurate travel time information of public transport vehicles is valuable for both operators and passengers. It helps operators effectively implement their management strategies. It also allows passengers to schedule their departure to minimize waiting times. Public transport travel time is affected by several factors such as traffic flow, passenger demand, etc, which have to b...
Maintaining genetic diversity is a crucial component in conserving threatened species. For the iconic Australian koala, there is little genetic information on wild populations that is not either skewed by biased sampling methods (e.g., sampling effort skewed toward urban areas) or of limited usefulness due to low numbers of microsatellites used. The ability to genotype DNA extracted from koala ...
The dog (Canis familiaris) is one of the most common predators in world with a population about 900 million, which continues to grow. Only 20% dogs are considered pets.

Roads have impacts on the fauna arising from habitat fragmentation, roadkill and barrier effect. Furthermore, roads lead species to change their activity with repercussions predator–prey interactions trigger indirect effects that are currently unknown. This study analyzes effect of a motorway trophic behavior terrestrial carnivore community its surroundings. Monthly scat sampling was conducted ...
