Abstract Purpose of Review Urbanization is increasing worldwide, transforming environmental and habitat parameters, and causing adverse effects on organisms living in urban habitats. Urban studies on ground beetles are exponentially increasing and cover all levels of biological organization. Still, to date, there is no comprehensive paper reviewing the impacts of urbanization on ground beetles at different levels of biological organization. Recent Findings At the population level, urbanization induces changes in the morphological characters, including fluctuating asymmetry, physiological condition, behavioral characteristics, seasonal activity, population size, and genetic diversity in ground beetles. Different species groups (habitat specialists vs. generalists, large vs. small-sized species, poor vs. good dispersers, predators vs. herbivores) respond differently to urbanization. Community-level changes associated with urbanization include the abundance, taxonomic as well as functional diversity, community assembly mechanisms, composition, and body size distribution. At the ecosystem level, urbanization influences several ecosystem processes and functions related to ground beetles, but data are only available concerning the edge effect and predation. Summary Urbanization has a considerable effect at various levels of the biological organization on ground beetles living in urban habitats. However, results—especially at the population and community levels—show inconsistent patterns. This discrepancy may result from individual responses and different sensitivity of species to urbanization, suggesting the importance of individualistic and functional approach in future urban studies. To preserve a rich carabid diversity in urban areas, multi-scale greenspace planning and management schemes are needed; these will also ensure both the recreational and the diversity-preserving function of urban green spaces.

Walking Time

Public green spaces have a high potential for a positive impact on people’s health and wellbeing, especially in urban areas. Studies on environmental justice indicate socially unequal access possibilities to urban green spaces. This article presents results on associations between individual socioeconomic position (SEP) and walking time from home to public green spaces in young people living in urban areas with more than 20,000 inhabitants in Germany. Data were derived from the German Environmental Survey for Children and Adolescents 2014–2017 (GerES V), the environmental module of the German Health Interview and Examination Survey for Children and Adolescents (KiGGS Wave 2). The sample comprises 1149 participants aged 3 to 17 years. A total of 51.5% of the participants reach a public green space on foot within five and 72.8% within ten minutes from home. The lower the participant’s SEP, the longer the walking time. Logistic regression models controlling for age group, sex, migration background, and region of residence show that participants with a low SEP have a significantly higher risk (odds ratio = 1.98; 95% confidence interval: 1.31–2.99) of needing more than ten minutes to walk from home to a public green space than participants with a high SEP. GerES V data indicate that young people living in urban areas in Germany do not equally benefit from the health-promoting potential of green spaces, which is an important aspect of environmental health inequalities.

Abstract As urban areas and land-use constraints grow, there is increasing interest in utilizing urban spaces for food production. Several studies have uncovered significant potential for urban growing to supplement production of fruit and vegetables, focusing on one or two cities as case studies, whilst others have assessed the global scale potential. Here, we provide a national-scale analysis of the horticultural production potential of urban green spaces, which is a relevant scale for agri-food and urban development policy making using Great Britain (GB) as a case study. Urban green spaces available for horticultural production across GB are identified and potential yields quantified based on three production options. The distribution of urban green spaces within 26 urban towns and cities across GB are then examined to understand the productive potential compared to their total extent and populations. Urban green spaces in GB, at their upper limit, have the capacity to support production that is 8x greater than current domestic production of fruit and vegetables. This amounts to 38% of current domestic production and imports combined, or >400% if exotic fruits and vegetables less suited to GB growing conditions are excluded. Most urban green spaces nationally are found to fall within a small number of categories, with private residential gardens and amenity spaces making up the majority of space. By examining towns and cities across GB in further detail, we find that the area of green space does not vary greatly between urban conurbations of different sizes, and all are found to have substantial potential to meet the dietary needs of the local urban population. This study highlights that national policies can be suitably developed to support urban agriculture and that making use of urban green spaces for food production could help to enhance the resilience of the national-scale food system to shocks in import pathways, or disruptions to domestic production and distribution.

One of the leading trends in contemporary cultural studies is the appealto the field of visual. Thepurpose of the article is to investigate the range of problems associated withthe existence, functioning of various visual practices in the urban space and the disclosure of the specifics of communication carried out through their intermediation. In urban space, there are many forms, such as monumental architecture, urban sculpture, outdoor illumination, landscape art, street art, graffiti and others. These artifacts are the subject of cultural research within different disciplines - aesthetics, cultural studies, design, and art. It may be noted that in recentdecades, significant development gets such a direction as Urban Studies, in which the focus of research serves the city. The methodology of the study includes an appeal to an interdisciplinary approach that relies on the achievements of practical cultural studies, Urban studies,and aesthetics theory by Ukrainian and Western authors. Scientific novelty consists in analyzing the connection ofactual visual practices presented in the urban space and forming of Internet activity, which facilitates the mutual influence of these spheres one on another. The author noted that urban space is gradually becoming not only interactive, but also fully assuming the characteristics of WEB 2.0, which means active rethinking and transforming the environment, urban residents involvement in decision-making that becomes a norm of everyday life. City is a kind of text that reflects changing tastes, politicaland economic factors in visualform. Town and city public spaces play an important role in shaping the interaction within society. One of the pressing problems of practical cultural studies in general and urban areas in particular, should be integrated into organization of the urban environment and design the image of the city. The practical significance lies in the fact that the results of the research can beused in developing the urban sphere in particular and in actualizing the issue of organizing the urban environment and constructing the image of the city.

Abstract Background: Despite the negative connotation of urban sprawl for bat populations, fragmented green spaces such as parks, cemeteries, and golf courses have the potential to provide necessary resources for bats. For example, water resources in these areas can include natural or semi-natural lakes, ponds, streams, and drainage ditches. Such water resources, however, are frequently ephemeral when subject to prolonged periods of high temperatures. We, therefore, hypothesize that bats will expand or shift their home ranges from these urban green spaces into the surrounding neighborhoods to access alternative resources, such as residential swimming pools. Methods: To explore whether bats expand their ranges from urban green spaces, we conducted a telemetry study in which we radio-tracked resident evening bats (Nycticeius humeralis) in a local park system during their summer activity period from 2017-2019 in Fort Worth, Texas, USA. From radio-tracking surveys, we measured home range size using a k-LoCoH method and the percentage of these home ranges that fell within the park system. We compared these variables using linear and non-linear regressions with temperature. Results: We successfully tracked a total of 30 bats over the 3-year period and found a positive correlation between home range size and temperature. Furthermore, we observed that home ranges increased 6 times in size when temperatures exceeded 30ºC. Conclusions: Our study indicates the importance of urban neighborhoods surrounding green spaces in providing alternative resources, such as water, for bats. If managed appropriately, these urban areas have the potential to act as urban oases for bat populations, which in turn can contribute to their conservation.

We compared the foraging activity of populations of Eptesicus fuscus in rural and urban settings in eastern Ontario and western Quebec by monitoring their echolocation calls and by radio tracking individuals during the summer of 1980. Foraging was detected in all of the rural and urban habitats we monitored. There were no significant differences in the levels of foraging activity over different urban habitats, but the overall foraging rates were significantly higher in the rural than in the urban areas. Foraging in rural areas was significantly higher in residential zones and over water and was less common in parkland and farmland. Bats in rural areas foraged among aggregations of insects at lights, a pattern of behaviour not seen among urban bats. Differences in foraging rates and the fact that rural bats spent significantly less time away from their roosts suggest that prey density was lower in the urban setting. Although urban habitats appear to provide E. fuscus with a wealth of roosting sites, food supplies are lower there.

Abstract Background: Obesity is rising in developing countries like India and is associated with an increase in cardiometabolic problems. Rising incomes, rapid urbanization, and mechanization have induced lifestyle changes like consumption of more obesogenic foods and sedentary habits at work and leisure, contributing to a transition from under- to over-nutrition. This study maps the prevalence of adult (15-49 years) overweight and obesity across regions and socioeconomic groups in India, and estimates its association with lifestyle, health environment, dietary patterns, diabetes, and hypertension.Methods: We employ a combination of 3 latest nationally representative datasets with over 700,000 adults. We use a linear probability regression model to identify the correlates of overweight/obesity and their relative magnitudes. We use intra-household regression to identify differences between men and women and coarsened exact matching to causally estimate the impact of obesity on diabetes and hypertension.Results: Overweight/obesity rates have increased across all states, in rural and urban areas, and for all wealth levels. Women are more likely to be overweight/obese than men, even in the same household. Improved health environment (toilets, piped water, clean cooking fuel), urban jobs, television watching, and processed snacks increase the risk of overweight/obesity. Adults who are overweight/obese have a 5.6% higher risk of diabetes and a 9.7% higher risk of hypertension.Conclusions: Our results underscore the need for policy intervention to reduce the burden of obesity and NCD’s in India.

The increases in urbanization, pollution, resource depletion, and climate change underline the need for urban planning policies that incorporate blue–green infrastructure (BGI) and ecosystem services. This paper proposes a framework for assessing BGI’s effect on children’s outdoor activities. This effect, called meaningful usefulness, is a central issue due to the influence of experiences with nature on children’s development and the global trend of concentration of children in urban areas. Based on the concept of affordance, the methodology formalizes meaningful usefulness in terms of an index of usefulness of individual settings (IUIS) and a synthetic index of usefulness of BGI in a specific area (ISGI). These are determined via an audit protocol, Opportunities for Children in Urban Spaces (OCUS), which incorporates a set of indicators measuring micro-scale properties of individual places and contextual macro-scale factors. The methodology is applied to BGI components in Cagliari, Sardinia, Italy, which was selected for its superior density of urban green spaces. The application of the OCUS tool confirms its usefulness for investigating functional affordances incorporated into the trans-scalar structures of BGIs. The analytic protocol further contributes to the implementation of urban planning strategies within the smart city paradigm.

Urban environmental issues such as declining air quality and increasing urban heat island effects can be managed by the effective use of urban green spaces. Consequently, the importance of green infrastructure (GI) has rapidly increased over time. While the various functions of GI have been investigated in numerous studies, limited research has focused on prioritizing those factors which impact the planning and development of GI. This study used literature reviews, expert surveys, and an analytic hierarchy process methodology to identify and prioritize the critical factors influencing GI during the design and construction process to enhance the role of GI in urban areas. Experts were asked to prioritize four primary (ecological, landscape, usability, and economic factors) and 16 secondary aspects of GI design. Respondents strongly agreed on the importance of the ecological aspects of GI, while the government sector also highlighted the importance of economic concerns, such as ongoing maintenance. Results indicated that the priorities for creating GI require further analysis and mediation between stakeholders. Further empirical evidence should be accumulated regarding the functions of GI for policy implementation in design and construction.

Abstract Understanding how wildlife respond to ever-encroaching urbanization is of great concern. Bats are the second-most speciose mammalian order and while many appear to be urban adapted, we currently have a limited understanding of their demography and habitat use within urban environments. Using a combination of captures to obtain demographic data, radio-telemetry to examine foraging and roosting behaviour, and data on diet and prey availability, we examined how big brown bats (Eptesicus fuscus), a synurbic species, use an urban green space (High Park) in Canada’s largest city centre, Toronto. We found that adult males outnumbered adult females more than two to one and that males were found throughout the park, while females were concentrated in an area with greater access to water, but lower prey availability. We also found that bats of both sexes were in poorer body condition than reported for other non-urban areas, including a site within southern Ontario. Our data suggest that High Park may not provide adequate resources for reproductive females as they were never found roosting in the park and beetles, their preferred prey, were limited. Although previous studies suggest urban green spaces may offer refuge to bats, most have not considered sex-specific responses to urbanization as they have largely been based on acoustic surveys. Our study therefore highlights the importance of considering demographic differences in response to urbanization to better inform urban management plans and green space development.

Urban habitats are drastically modified from their natural state, creating unique challenges and selection pressures for organisms that reside in them. We compared locomotor performance of Anolis lizards from urban and forest habitats on tracks differing in angle and substrate, and found that using artificial substrates came at a cost: lizards ran substantially slower and frequently lost traction on man-made surfaces compared to bark. We found that various morphological traits were positively correlated with sprint speed and that these same traits were significantly larger in urban compared to forest lizards. We found that urban lizards ran faster on both man-made and natural surfaces, suggesting similar mechanisms improve locomotor performance on both classes of substrate. Thus, lizards in urban areas may be under selection to run faster on all flat surfaces, while forest lizards face competing demands of running, jumping and clinging to narrow perches. Novel locomotor challenges posed by urban habitats likely have fitness consequences for lizards that cannot effectively use man-made surfaces, providing a mechanistic basis for observed phenotypic shifts in urban populations of this species.
