Currently in Ecuador there are 171 bats species, however little is known of their presence in urban and peri-urban areas. These information gaps make it difficult to know the distribution of the species, as well as the ecosystems they are occupying. In this work we report for the first time three bats species in the urban and peri-urban area of Cuenca City which is located in the south of the Inter-Andean Valley. The individuals were identified taxonomically by morphological and morphometric characters, these were deposited in the Zoological Collection of the University of Azuay. The specimens reported in this work are: an adult male of Lasiurus blossevillii, a juvenile female of Histiotus humboldti, and an adult male of Enchisthenes hartii. These new records allow us to contribute with information on the distribution of these species, as well as raise new questions about the use of present resources by these bats in the urban and peri-urban environments of the city.

Migration studies have always found their unique place in anthropology since the birth of anthropology in India under colonial rule. From the formative phase, anthropology of migration has grown multifold. In the present time when the Indian diaspora is the largest in the whole world, the process of migration has affected the lives of all individuals and has become an important area of research. The present article examines the growth of this field in sociocultural anthropology in India and is based on secondary data. Work of renowned Indian anthropologists like M. N. Srinivas, Moni Nag, L. P. Vidyarthi, Amitav Ghosh and others like R. K. Jain, Ashish Bose, etc. on migration has been discussed in the present article. Migration studies in India have found and sustained a key place in the anthropology curriculum report since the first time of its release by the University Grants Commission, New Delhi. Migration studies have grown from studying mobility among the tribals to the movement of people from rural to urban areas and then to international migration. New areas like displacement and refugee movements, literature and art, diaspora studies, urbanism, labour migration and many more are emerging as important topics in the landscape of migration studies.

Background: A number of books, articles and checklists have been published on Lesotho’s flora. The species presented here have been recorded for South Africa but have not previously been recorded for Lesotho.Objectives: As part of a study aimed at updating biodiversity records of the southern parts of Lesotho (Qacha’s Nek and Quthing districts), with the main focus of compiling a checklist for the Sehlabethebe National Park, this report presents plant species that have until now not been recorded for the Lesotho flora.Method: Several field trips were undertaken between 2004 and 2009. Plant identification was done based on observation and photographic records. After the compilation of the checklist, it became clear that two of the species observed had not been previously recorded for Lesotho. A follow-up trip was carried out in February 2016, during which plant specimens of the presumed new records were collected and deposited at the National University of Lesotho Herbarium (ROML) [and the University of Johannesburg Herbarium (JRAU)]. Plant identification was confirmed by experts in the family Apocynaceae.Results: Two species not previously recorded for Lesotho, namely Ceropegia africana subsp. barklyi and Duvalia caespitosa subsp. caespitosa, were found during the exploration of the southern parts of Lesotho which included the Sehlabathebe National Park.Conclusions: The fact that two species have been recorded in Lesotho for the first time clearly indicates that documentation of the flora of Lesotho needs to be updated. This work is therefore regarded as complementary to previous publications on the Lesotho flora.

The forests of Costa Rica are rich in a wide variety of pollinator types and a very diverse flora that supports them.  Our research group from the University of California, Berkeley and Texas A & M University, College Station has been researching the ecology of one pollinator group, the bees, in the northwest Guanacaste dry forest region since 1969.  Much natural forest existed in this area when we first began the work.  But, many land use changes have occurred over the years to present day to the point that it is difficult to find tracts of undisturbed forest suitable for field research, especially those not affected by wildfires, which are now common.        Further, urban areas in the region continue to grow with increasing numbers of people populating the region.  In this paper we provide an overview of our past bee-flower work for a historical perspective, and then weave in people that have now become an obvious ecological component of current bee-flower relationships.  We also explore new questions that have become relevant through time, especially those related to researchers and potential conservation opportunities to share their stories with audiences that may extend their knowledge for practical use.  Finally, we propose that researchers plan to devote some of their precious time establishing relationships with people in conserving what is left of bee-flower relationships in urban environments in Guanacaste and beyond in the country.  Avenues for extending this knowledge are explored in this paper.

Amoeba-resistant bacteria (ARB), such as Legionella spp., are currently regarded as potential human pathogens that live in the natural environment, and thus their habitat is regarded as a reservoir of human pathogens. To detect ARB in human and environmental samples, co-culture with amoebae has been demonstrated to be an efficient tool. However, to date, only water samples from cooling towers and hospital water supplies have been investigated as possible reservoirs of ARB using this procedure. In the present study, we studied the ARB population of 11 diverse soil and sand sources in proximity to human environments; these sources included the university, the station, hospitals, the square, parks and public beaches in the city of Marseilles, France. As a result, a total of 33 different species of ARB were identified. The ability to grow within and/or lyse amoebae was demonstrated, for what is believed to be the first time, for several species; moreover, 20 of the isolates (61 %), including Streptococcus pneumoniae, have been described as human pathogens. However, Legionella spp. were not isolated. Four isolates are likely to be the members of new or uncharacterized genera or species, and their capability to be human pathogens needs to be determined. This preliminary work demonstrates that soils and sands in the vicinity of humans are reservoirs of human pathogenic ARB.

The university establishment process in Konya started in the 1950s for the first time. After 1960s, the institutions giving higher education in the city came into activity, and in 1976 Selçuk University was established. Selçuk University, since its establishment, has lead the single-centered city to develop towards the north, and at the same time, also the campus as a center of attraction has caused a shift of the population concentration to the region. The university, which makes good use of the city's potentials in the change of the city form, also made it possible to create surplus values by using the values that the city has in the fields of agriculture, agriculture industry, and technology. The Selçuk University Alâeddin Keykubat Campus is still a potential force that creates economic surplus, attracts population and shapes the city.

Changes in urban areas are happening faster than they are being mapped. Modern methods of collecting topographic information and conducting topographic monitoring allow you to quickly track and record these changes. Retrospective cartographic data contain valuable geographical information about territories in historical terms. The purpose of the article is to study the changes in the territory by means of geospatial-retrospective analysis on the example of the city of Kharkiv. This article proposes for the first time the use of geospatial-retrospective analysis to study changes in territories on the example of the city of Kharkiv. To find the geospatial pattern of development of boundaries and changes in the area of the city of Kharkiv, a geospatial-retrospective analysis was performed, the results of which confirmed the high rate of increase in the area and boundaries of the city.

Studies show that electromobility will emerge in urban areas. As urban mobility solutions are changing, electromobility is intended with a big potential of sustainable innovation. Nevertheless, changing the mobility culture depends on certain requirements. According to Urri, the automobile development lies in breaking the dominant role of cars which results in a development deadlock. In order to change the mobility culture, the mental approach to mobility options and the infrastructural conditions need to be considered as two central factors. Future mobility isn´t about less mobility, but rather a different way of being mobile and using different types of mobility solutions. This paper presents a research project that is based on the systemic-relational approach. It seeks to develop and introduce the conditions of electromobility in an urban area without a well-frequented local public transport by a networked innovation cooperation in four development areas. The central goal of this work is the integrated development of service innovation of technical and non-technical manner based on the network of project partners, the city council and the university. A change towards electromobility means changing infrastructure, market actors and business models. It signifies a change of social-cultural systems regarding mobility habits, practices and values. One of our main results show that the emotional perception by using experiences of electromobility has a positive effect on its social acceptability which raises the “flow factor” of electromobility.

Abstract. The majority of anthropogenic CO2 emissions are attributable to urban areas. While the emissions from urban electricity generation often occur in locations remote from consumption, many of the other emissions occur within the city limits. Evaluating the effectiveness of strategies for controlling these emissions depends on our ability to observe urban CO2 emissions and attribute them to specific activities. Cost effective strategies for doing so have yet to be described. Here we characterize the ability of a prototype measurement network, modeled after the BEACO2N network, in combination with an inverse model based on WRF-STILT to improve our understanding of urban emissions. The pseudo-measurement network includes 34 sites at roughly 2 km spacing covering an area of roughly 400 km2. The model uses an hourly 1 × 1 km2 emission inventory and 1 × 1 km2 meteorological calculations. We perform an ensemble of Bayesian atmospheric inversions to sample the combined effects of uncertainties of the pseudo-measurements and the model. We vary the estimates of the combined uncertainty of the pseudo-observations and model over a range of 20 ppm to 0.005 ppm and vary the number of sites from 1 to 34. We use these inversions to develop statistical models that estimate the efficacy of the combined model-observing system at reducing uncertainty in CO2 emissions. We examine uncertainty in estimated CO2 fluxes at the urban scale, as well as for sources embedded within the city such as a line source (e.g., a highway) or a point source (e.g., emissions from the stacks of small industrial facilities). We find that a dense network with moderate precision is the preferred setup for estimating area, line, and point sources from a combined uncertainty and cost perspective. The dense network considered here could estimate weekly CO2 emissions from an urban region with less than 5 % error, given our characterization of the combined observation and model uncertainty.

Urban ecosystems are an increasingly dominant feature of terrestrial landscapes. While evidence that species can adapt to urban environments is accumulating, the mechanisms through which urbanization imposes natural selection on populations are poorly understood. The identification of adaptive phenotypic changes (i.e. clines) along urbanization gradients would facilitate our understanding of the selective factors driving adaptation in cities. Here, we test for phenotypic clines in urban ecosystems by sampling the frequency of a Mendelian-inherited trait—cyanogenesis—in white clover ( Trifolium repens L.) populations along urbanization gradients in four cities. Cyanogenesis protects plants from herbivores, but reduces tolerance to freezing temperatures. We found that the frequency of cyanogenic plants within populations decreased towards the urban centre in three of four cities. A field experiment indicated that spatial variation in herbivory is unlikely to explain these clines. Rather, colder minimum winter ground temperatures in urban areas compared with non-urban areas, caused by reduced snow cover in cities, may select against cyanogenesis. In the city with no cline, high snow cover might protect plants from freezing damage in the city centre. Our study suggests that populations are adapting to urbanization gradients, but regional climatic patterns may ultimately determine whether adaptation occurs.
