Red Foxes (Vulpes vulpes) pose a significant threat to small native mammals in Australia (Saunders et al. 1995) and may restrict the recovery of some populations of native mammals and birds (Norman, Cullen and Dann 1992; Augee, Smith and Rose 1996; Priddel and Wheeler 1996; Seebeck and Booth 1996; Smith and Quin 1996). In the Adelaide area V. vulpes are wide- spread in the hills. They are often reported near houses and are a nuisance because of their predation on backyard poultry. Within Belair National Park, an area of 840 ha located in the Adelaide hills about 8 km from the City Centre, foxes are a potential danger to small native mammals, such as the Southern Brown Bandicoot (lsoodon obesulus).There is a small population of I. obesulus in Belair National Park, (Regel et al. 1996) of which 62 individuals from an area of about 30 ha were recently marked with microchips. A fox baiting program with Foxoff® in autumn 1996 in Belair National Park saw the uptake of 97 poisoned baits, with two fox carcasses located.

Phylogenetic Status

Abstract The red fox (Vulpes vulpes) is a medium-sized carnivore that occurs in different regions of Pakistan, however, still lacks scientific data on its ecology and distribution. The current study investigated the phylogenetic status and diet of the red fox (V.v. griffithii) occurring in Ayubia National Park, Pakistan. Through camera trapping and molecular analysis, we confirmed the occurrence of red fox in the study area. Based on mitochondrial cytochrome B (304 bp) and limited sampling, nearly all red foxes of Ayubia National Park and surrounding Himalayan ranges fall within Holarctic maternal lineage, whereas red foxes found in plains of Pakistan are part of the basal Palearctic maternal lineage. Using 32 scats, we found that red fox diet comprises of 80% animal-based prey species (both wild and domestic) and 19% plant matter. The wild animal prey species included Cape hare (Lepus capensis) and flying squirrel (Pteromyini sp.), which constituted 17% and 15% of diet, respectively. Red foxes infrequently consumed House mouse (Mus musculus), Himalayan Palm civet (Paguma larvata) and sheep (Ovis aries), each comprising around 6% to 9% of red fox diet. The fox species also scavenged on domestic donkey opportunistically. Based on our sampling, our study suggests that the red fox (V.v. griffithii) that occurs in Ayubia National Park and across the lesser Himalayan ranges belongs to Holarctic maternal lineage. The study also highlights consumption of plant seeds by red foxes, indicating it may play an important ecological role in seed dispersal in Ayubia National Park.

Forty-three coyotes, 12 wolves, and 6 red foxes from an area around Riding Mountain National Park in southwestern Manitoba were examined for parasitic helminths. Eleven, 8, and 5 species were found in coyotes, wolves, and red foxes, respectively. Alaria marcianae, Alaria arisaemoides, and Toxascaris leonina were found in all three host species; Echinococcus granulosus, Taenia hydatigena, Uncinaria stenocephala, and Oslerus (Oslerus) osleri in wolves and coyotes; and Echinococcus multilocularis in coyotes and red foxes. Taenia pisiformis and T. leonina were the most prevalent species in coyotes; E. multilocularis and E. granulosus, the most numerous. Echinococcus granulosus was the most prevalent and numerous species in wolves. Alaria marcianae and T. leonina were found in all red foxes. The significance of the coyote as a major definitive host of E. multilocularis in southwestern Manitoba is discussed.

The M-44 ejector (ejector) is a more target-specific means of lethal control of red foxes (Vulpes vulpes) than conventional meat baits, which may expose a wide range of non-target species to the bait toxicant. Owing to the threshold pulling force required to activate the ejector, undesired exposure is eliminated in many smaller animals that cannot generate this force. However, the spotted-tailed quoll (Dasyurus maculatus) and the Tasmanian devil (Sarcophilus harrisii) remain potential non-target species because of their larger size. In this study, we report on the development of a collar that excludes devils and quolls by exploiting differences in their head morphology relative to that of red foxes. The collar potentially prevents bait removal by larger non-target species, while still allowing all adult foxes access to the bait to trigger the ejector mechanism. Spotted-tailed quolls small enough to access the bait are theoretically too small to trigger the ejector mechanism set at a threshold pulling force of 2.7 kg.

This paper examines how mass ridership data can help describe cities from the bikers' perspective. We explore the possibility of using the data to reveal general bikeability patterns in 202 major Chinese cities. This process is conducted by constructing a bikeability rating system, the Mobike Riding Index (MRI), to measure bikeability in terms of usage frequency and the built environment. We first investigated mass ridership data and relevant supporting data; we then established the MRI framework and calculated MRI scores accordingly. This study finds that people tend to ride shared bikes at speeds close to 10 km/h for an average distance of 2 km roughly three times a day. The MRI results show that at the street level, the weekday and weekend MRI distributions are analogous, with an average score of 49.8 (range 0–100). At the township level, high-scoring townships are those close to the city centre; at the city level, the MRI is unevenly distributed, with high-MRI cities along the southern coastline or in the middle inland area. These patterns have policy implications for urban planners and policy-makers. This is the first and largest-scale study to incorporate mobile bike-share data into bikeability measurements, thus laying the groundwork for further research.

Small-scale spatial variability in NO2 concentrations is analysed with the help of pollution maps. Maps of NO2 estimated by the Airviro dispersion model and land use regression (LUR) model are fused with measured NO2 concentrations from low-cost sensors (LCS), reference sensors and diffusion tubes. In this study, geostatistical universal kriging was employed for fusing (integrating) model estimations with measured NO2 concentrations. The results showed that the data fusion approach was capable of estimating realistic NO2 concentration maps that inherited spatial patterns of the pollutant from the model estimations and adjusted the modelled values using the measured concentrations. Maps produced by the fusion of NO2-LCS with NO2-LUR produced better results, with r-value 0.96 and RMSE 9.09. Data fusion adds value to both measured and estimated concentrations: the measured data are improved by predicting spatiotemporal gaps, whereas the modelled data are improved by constraining them with observed data. Hotspots of NO2 were shown in the city centre, eastern parts of the city towards the motorway (M1) and on some major roads. Air quality standards were exceeded at several locations in Sheffield, where annual mean NO2 levels were higher than 40 µg/m3. Road traffic was considered to be the dominant emission source of NO2 in Sheffield.

Knowledge about urban forests in Poland is still limited, as it is primarily based on aggregate, formal data relating to the general area, ignoring the spatial dimension and informal green areas. This article describes and analyses spatio-temporal changes in the actual urban forest resources in Wrocław in 1944–2017, which covers the first period of the city’s rebuilding after its destruction during World War II and its development during the nationalised, centrally-planned socialist economy, as well as the second period of intensive and only partly controlled growth under conditions of market economy. The study is based on current and historical orthophotomaps, which were confronted with cartographic data, as well as planning documents. We found that between 1944 and 2017, the percentage contribution of informal woodlands increased tenfold (from 0.5 to 4.9% of the present total area of the city). The area occupied by such forests has grown particularly during the most recent years of the city’s intensive development. However, the forests have been increasingly fragmented. During the first period, new forest areas were also created in the immediate vicinity of the city centre, while during the second one, only in its peripheral sections. The post-war plans regarding the urban green spaces (UGS), including the current plan, are very conservative in nature. On the one hand, this means no interference with the oldest, biggest, and most valuable forest complexes, but on the other hand, insufficient consideration of the intensive built-up area expansion on former agriculture areas. Only to a limited extent did the above-mentioned plans take into account the informal woodlands, which provide an opportunity for strengthening the functional connectivity of landscape.

Santiago de Compostela is an iconic place. From the 9th century through to the present day the city has acted as the final destination of a major pilgrimage route named after it. In the article we ask ourselves how the contemporary reinvention of the pilgrimage and pilgrimages on the Way of St. James has boosted tourism development in the city. Development has been concentrated in the historic city centre and in the area around the cathedral. The importance of tourism has transformed the significance of the city itself, which acquires a magical component as a place of arrival and encounter for all kinds of visitors. The historic city has been set up in the 20th century as a destination for the Way and for cultural tourism. The buildings, particularly those connected with the pilgrimage route, become highly attractive and symbolic places and tourists carry out a number of rituals in them. They travel and enjoy Santiago as a unique experience. The study of tourism and of the tourist transformation of Santiago de Compostela is undertaken using a qualitative and quantitative method. The article analyses the heritage and symbolic value of the historic centre, together with the growth of its tourism activities. Numerical data are also provided on the perceptions and behaviour of visitors using surveys carried out by the city's Tourism Observatory.
