This article explores the relationship between the nation, the city, narratives, and belonging in Serbia through an analysis of narratives of a set of 30 interviews with young Belgrade intellectuals aged 23-35. I argue that what appears to be emerging in post-Milosevic Serbia is a new articulation and a new scale of belonging. Most of my informants are mobilising their city identities, moving from a national to an urban perspective. They imaginatively defend their city identity through a discourse that, others' its newcomers, i.e. the rural residents. However, the article is critical of their articulated dichotomous rhetoric of 'Us, the City Cosmopolitans' vs. I Them, the Rural Nationalists' My overall aim is to offer an analysis of the Serbian case, where one sees that the city of Belgrade has become a microcosm and a symbolic expression for modernity, resistance, openness and democracy. However, instead of seeing urbanity as the only locus of modernity, one needs to understand that urbanity does not one-dimensionally lead to the urbanisation of the mind, implying that once you have cities, or live in a city, there is a specific urban, cosmopolitan experience.

We evaluated metacommunity hypotheses of landscape arrangement (indicative of dispersal limitation) and environmental gradients (hydroperiod and nutrients) in structuring macroinvertebrate and fish communities in the southern Everglades. We used samples collected at sites from the eastern boundary of the southern Everglades and from Shark River Slough, to evaluate the role of these factors in metacommunity structure. We used eigenfunction spatial analysis to model community structure among sites and distance-based redundancy analysis to partition the variability in communities between spatial and environmental filters. For most animal communities, hydrological parameters had a greater influence on structure than nutrient enrichment, however both had large effects. The influence of spatial effects indicative of dispersal limitation was weak and only periphyton infauna appeared to be limited by regional dispersal. At the landscape scale, communities were well-mixed, but strongly influenced by hydrology. Local-scale species dominance was influenced by water-permanence and nutrient enrichment. Nutrient enrichment is limited to water inflow points associated with canals, which may explain its impact in this data set. Hydroperiod and nutrient enrichment are controlled by water managers; our analysis indicates that the decisions they make have strong effects on the communities at the base of the Everglades food web.

The current study includes theoretical and methodological reflections on the quality of life in the city of Uberlândia, Minas Gerais. It started from the thought that the quality of life is multifactorial and is permanently under construction and the main objective of analyzing it as one of the componets of Healthy Cities's moviment. The theoretical research focused on the concepts of healthy cities, quality of life, health, sustainability, well-being, happiness, indexes and indicators. From the use of multiple search strategies, documentary and on field of quantitative and qualitative character, this research of exploratory descriptive nature can offers a contribution to the studies on the quality of life in cities. It is proposed that the studies startes to work with some concept, like some notions os life quality adequated for some paticular reality, whose notions can approach concepts already established as health. This step is important on the exploratory researches. The studies may include aspects of objective analysis, subjective or both. The objective dimension, which is most common approach, are traditionally considered variables and indicators related to: the urban infrastructure (health, education, leisure, security, mobility), dwelling (quantitative and qualitative dwlling deficit), the urban structure (density and mix uses), socioeconomic characteristics (age, income, education), urban infrastructure (sanitation, communication), governance (social mobilization and participation). To focus on the subjective dimension, most recent and unusual, it is proposed to consider the (dis)satisfaction, the personal assessment in relation to the objective aspects. In conclusion, being intrinsically related to the health, the quality of life also has a number of determinants, and the ideal of the reach of quality of life depends on the action of all citizens based on the recognition of networks and territories, in a interescalar perspective and intersectoral. Therefore, emphasis in given on the potential of tools, such as the observatories, to monitor and intervent in reality, aiming in a building process of healthy cities.

Au courant de la période industrielle, la ville de Québec a connu une croissance démographique rapide alimentée, entre autres, par une immigration européenne massive. Celle-ci contribua d’une façon notable aux changements socioéconomiques de la capitale durant cette période. Parmi les migrants, les Irlandais catholiques furent nombreux à transiter ou à s’établir à Québec et y laissèrent des traces encore visibles aujourd’hui. Or, bien que l’histoire de la diaspora irlandaise en sol nord-américain ait fait l’objet de plusieurs recherches, le cas de la ville de Québec, tout comme sa période d’industrialisation, reste encore peu étudié à ce jour. Grâce à l’utilisation des recensements nominatifs canadiens de 1852 à 1911 et des actes de mariage, cette étude a comme objectif d’analyser le niveau d’intégration de la communauté irlandaise de Québec sur les plans économique, social et spatial, et ce, à micro-échelle. Ainsi, en observant les emplois et la mobilité socioprofessionnelle des travailleurs, les unions exogames et l’évolution de l’établissement irlandais sur le territoire à l’étude, la présente recherche permet d’établir un constat positif : les Irlandais catholiques ont su s’intégrer à la société urbaine de Québec. Néanmoins, considérant la forte diminution démographique de la communauté au tournant du siècle, l’intégration s’est effectuée davantage à l’échelle des ménages que pour l’ensemble de la communauté.

Ponds are common and abundant landscape features in temperate environments, particularly on floodplains where lateral connectivity with riverine systems persists. Despite their widespread occurrence and importance to regional diversity, research on the ecology and hydrology of temperate ephemeral and perennial floodplain ponds lags behind that of other shallow waterbodies. This study examines the aquatic macroinvertebrate diversity of 34 ponds (20 perennial and 14 ephemeral) on two unregulated riverine floodplain meadows in Leicestershire, UK. Perennial ponds supported nearly twice the diversity of ephemeral ponds. Despite frequent inundation of floodwater and connectivity with other floodplain waterbodies, ephemeral ponds supported distinct invertebrate communities when compared to perennial ponds. When the relative importance of physical and chemical, biological and spatial characteristics was examined, physical and chemical characteristics were found to account for more variation in community composition than biological or spatial variables. The results suggest that niche characteristics rather than neutral colonisation processes dominate the structure of invertebrate communities of floodplain ponds. The maintenance of pond networks with varying hydroperiod lengths and environmental characteristics should be encouraged as part of conservation management strategies to provide heterogeneous environmental conditions to support and enhance aquatic biodiversity at a landscape scale.

Urbanization is a global process contributing to the loss and fragmentation of natural habitats. Many studies have focused on the biological response of terrestrial taxa and habitats to urbanization. However, little is known regarding the consequences of urbanization on freshwater habitats, especially small lentic systems. In this study we examined aquatic macroinvertebrate diversity (family and species level) and variation in community composition between 240 urban and 782 non-urban ponds distributed across the UK. Contrary to predictions, urban ponds supported similar numbers of invertebrate species and families compared to non-urban ponds. Similar gamma diversity was found between the two groups at both family and species taxonomic levels. The biological communities of urban ponds were markedly different to those of non-urban ponds and the variability in urban pond community composition was greater than that in non-urban ponds, contrary to previous work showing homogenisation of communities in urban areas. Positive spatial autocorrelation was recorded for urban and non-urban ponds at 0-50 km (distance between pond study sites) and negative spatial autocorrelation was observed at 100-150 km, and was stronger in urban ponds in both cases. Ponds do not follow the same ecological patterns as terrestrial and lotic habitats (reduced taxonomic richness) in urban environments; in contrast they support high taxonomic richness and contribute significantly to regional faunal diversity. Individual cities are complex structural mosaics which evolve over long periods of time and are managed in diverse ways, promoting the development of a wide-range of environmental conditions and habitat niches in urban ponds which can promote greater heterogeneity between pond communities at larger scales. Ponds provide an opportunity for managers and environmental regulators to conserve and enhance freshwater biodiversity in urbanized landscapes whilst also facilitating key ecosystem services including storm water storage and water treatment.
