Urban green spaces (UGS), such as parks and wooded streets, are open areas with vegetation that provide sustainability to urban areas. However, their role in conserving bird diversity in neotropical cities has scarcely been analyzed. The aim of this study was to analyze the variation of bird assemblages in non-wooded streets, wooded streets, and parks in Buenos Aires City, Argentina. We compared the taxonomic and functional diversity between these habitat types. We selected five non-wooded streets, five wooded streets, and five parks in the city. Bird surveys were performed in 100 m long and 50 m wide transects. We found that taxonomic diversity had the greatest value in the parks, followed by wooded streets, and then the non-wooded streets. Functional diversity was similar between habitats. The taxonomic and functional composition changed between habitats. Non-wooded streets were dominated by the Rock Dove (Columba livia) and the Eared Dove (Zenaida auriculata), whereas parks had the highest abundance of the Picazuro Pigeon (Patagioenas picazuro) and the Rufous-bellied Thrush (Turdus rufiventris). Non-wooded streets were dominated by omnivorous and granivorous species, whereas parks had a higher abundance of herbivorous and frugivorous species. The positive association between UGS and bird diversity highlights the role of UGS as biodiversity conservation sites in neotropical cities.

Urban scape constitutes the manifestation of various natural and anthropic elements entangled in a specific form. However, arbitrary land-use changes during the last few decades have witnessed a significant biodiversity loss in urban areas. Over 50% of the earth’s human population lives in the urban settlement, which accounts for less than 3% of the earth’s urbanized area. Urban green spaces act as biodiversity refuge in urban areas. In such crucial circumstances, an urban forest can play a critical role in biodiversity conservation and management through academic green spaces. To understand and evaluate the role of the urban forest, the present study carried out on the campus of [CSIR-National Environmental Engineering Research Institute (NEERI)], Nagpur. Furthermore, an innovative and multifaceted index named total importance value (TIV) index was developed, which used to analyze the importance of the trees present on the campus. Results revealed the presence of more than 200 plant species belonging to both native and exotic groups and their contributions to improve the urban environment in terms of the TIV index. The study also advocates the usages of TIV as a framework for the development and planning of climate-smart green cities, which is resilience to climate change.

Nocturnal Feeding

AbstractArtificial light at night (ALAN) is one of the most extreme alterations of urban areas, which drives nocturnal activity by diurnal species. Although the Rock Dove (Columba livia) is a common species in urban centers worldwide known to have nocturnal activity in urban areas, it is unknown what is the role of ALAN in its nocturnal activity. Moreover, studies that address the relationship between ALAN and nocturnal activity of diurnal birds are scarce in the Southern hemisphere. The objectives of this study were: 1) to evaluate the extent of nocturnal activity in the Rock Dove in large cities of Argentina; and 2) to analyze the influence of ALAN, pedestrian traffic and car traffic on the nocturnal activity in two cities, Buenos Aires and Salta. I visited the most urbanized areas of five large cities in Argentina, and surveyed lighted streets once after 30 minutes after sunset. In Buenos Aires and Salta, I compared environmental conditions between sites were doves were seen feeding with random sites were doves were not recorded feeding. Nocturnal feeding of the Rock Dove was recorded in three of five cities surveyed. ALAN was positively related to nocturnal feeding activity in Salta and Buenos Aires. The results obtained suggest that urbanization promotes a nocturnal activity of the Rock Dove, which occurs in cities located in a vast range of altitudes and biogeographic contexts. Moreover, the nocturnal activity is mainly driven by ALAN, which probably alters the circadian rhythm of doves.

That illegal markets thrive is something of a puzzle to sociology. Despite the lack of legal frames—crucial for conflict resolution, regulation of competition, and formal sources of credit—new illegal markets continue to emerge. Thus an analysis of informal social mechanisms is essential for a better understanding of illegal markets’ internal coordination. The main goal of this chapter is to dissect the role of one of these mechanisms—state-sponsored protection rackets—in the context of illegal markets. This type of protection racket means a selective non-enforcement of the law, an action carried out intentionally by politicians and police forces in order to capture economic resources. I provide evidence that such an informal mechanism is present on a massive scale at La Salada, a huge illegal and informal marketplace close to Buenos Aires city center. The chapter seeks to make a contribution on informal mechanisms fostering unlawful exchanges.

In this work, we aim to study the role culture plays as an economic resource, especially for tourism promotion. Such conception is the result of changes in urban planning, international tourism tendencies and economy, politics and culture in general. Culture can generate income through tourism, crafts and other cultural activities.” Such urban transformations in Buenos Aires city have increased since the end of convertibility and become the essential resource for development. In order to carry out this study, we have worked with secondary statistical information elaborated by local administration institutions, such as the Ministry of Culture (Buenos Aires City Government) and CEDEM (Studies Center for Metropolitan Economic Development, Secretary of Economic Development, Buenos Aires City Government). This methodology helps us analyse the increase not only of artistic activities but of the consumption of cultural services through tourism, especially with the construction and promotion of tango as a trademark for Buenos Aires city.

AbstractThe aim of this study was to evaluate the role of the brown rat (Rattus norvegicus) as a potential reservoir of zoonotic parasites in an urban area of Argentina. A parasitological survey in 40 brown rats trapped in a shantytown of Buenos Aires City was carried out. 97.5 % of the analyzed rats were parasitized with at least one of the 12 species of helminth or protozoan species recorded. Among the species identified, Hymenolepis nana is recognized as one of the most common human helminthes parasites. The average number of parasite species was higher in males than females rats, and in the last case, a direct relationship between parasite species richness and host’s body size was recorded. Variations in endoparasite community throughout the year seasons were recorded, probably related to environmental factors, which limits the performance of the life cycle of different parasite species. The presence of zoonotic endoparasites confirms R. norvegicus as a reservoir for different types of pathologies, which, therefore, represents a risk to the public health in an overcrowded urban area.

Capturing the rural markets brings forth a whole new set of challenges as it is laborious to break in. This market presents the companies with gamut challenges on a new dimension which demand entirely different strategies as compared to the ones used in urban areas. Studying the rural markets for rural markets has become crucial more than ever. It is an objective learning, psychiatry of dispersion, impact of the FMCG in rural areas. This research uses diverse utensils, procedure toward analyze composed records. Several of the features used in analyzing the data are the consumer characteristics like educational qualifications, professions they are in, and the income levels.
