We present an overview of a study on bees carried out by the Centre Vétérinaire de la Faune Sauvage et des Écosystèmes (CVFSE, Nantes, France) between 2014 and 2018. Bees were collected through net sampling in 84 sites located in 43 cities of the French region Pays de la Loire (32 cities in Loire-Atlantique, 4 in Maine-et-Loire, and 7 in Vendée). Sampling occurred in different types of habitats: urban areas, agricultural areas, and semi-natural habitats like grasslands, woodlands, and coastal zones. This study provided information on the distribution of 278 bee species, among which several were previously unknown to the Armorican Massif (Andrena florivaga, Chelostoma distinctum, Coelioxys obtusa, Eucera clypeata, E. pannonica, Hylaeus clypearis, H. leptocephalus, H. punctatus, Lasioglossum tarsatum, Nomada errans, N. furva, N. lisenmaieri, N. rubiginosa, N. villosa, and Sphecodes pseudofasciatus). It highlighted the great bee species richness in semi-natural habitats, notably in the coastal dunes, but also in some urban or suburban sites, as long as the management is favourable to bees.

Natural habitats and their biodiversity are usually associated with protected areas, incompatible with direct anthropogenic influence. Is there a biodiversity in urban environment, what is the role of peri-urban areas to the provision of species richness and is their potential being properly utilized? These are current issues that deserve the attention of decision-makers because the human's need of natural environment in cities is expressed more intensely than in any previous period in history. Green and blue infrastructure elements, being part of the larger system of urban ecosystems, provide an essential and proven benefits to the city dwellers, like health improvement, opportunities for nature-based daily outdoor recreation, strengthening sense of place etc. The main objective of this research is to assess this part of the landscape elements in urban and peri-urban environment, which are most supportive to the maintenance of habitats and their biodiversity. Selected Functional urban area with center city of Burgas is choosen for a case study. The urban ecosystems are assessed in GIS environment with unified indicator (based on City Biodiversity Index approach) according to 5 criteria: hemeroby index, share of protected areas, fragmentation index, presence of water and species richness. The assessment is performed on two spatial levels: within Functional urban area by Urban Atlas spatial units and within urban core – by grid cells (local climate zones). The final higher scores identify areas that provide the greatest extent the maintenance of habitats and their biodiversity. The results could support the urban planning and help to optimize the link between the natural elements within the Functional urban areas, providing ecological, economic and social benefits to the regions through the enhancement of the urban ecosystem’s functions and their services.

The list of birds of Sindhudurg coastal district was compiled based on primary and secondary information.  All observations were made along the Sindhudurg coast, i.e., from Terekhol to Vijaydurg.  Wetland birds were recorded during sampling while terrestrial birds were recorded opportunistically.  Besides, we also collated bird occurrence records from published literature (including grey literature and online resources) to prepare a comprehensive list of birds for Sindhudurg coast.  During our study, we recorded 283 species, and 24 more species were compiled from secondary sources.  Altogether, 307 species belonging to 78 families and 22 orders were recorded from the Sindhudurg coast.  Order Passeriformes was dominant with 111 species.  Among the 307 species, four species are endemic to the Western Ghats.  Three species of vultures had been reported earlier but two were not encountered in recent years.  Great Knot (EN), Woolly-necked Stork (VU) and 14 other species (NT) fall under various threat categories of IUCN.  Species richness was higher in Vengurla (256) followed by Malvan (247) and Devgad talukas.  Construction of homestays, unregulated tourism in coastal areas, and conversion of natural habitats to meet increasing tourism are the major threats to the coastal avifauna of the district.  A high species richness of birds in Sindhudurg coast is attributed to the availability of a wide array of habitats (coastal to woodlands with different degrees of anthropogenic disturbances).  Considering the high species richness of birds and livelihood dependency of humans on the coastal zones, a few estuaries namely Mochemad, Karli and Mitbav estuaries may be recognized as community/ conservation reserve to manage the ecosystem sustainably for long-term conservation of these estuaries and sub-habitats therein.  Also, those sites can be perceived as Important Bird and Biodiversity Areas of IBCN as they fulfill the IBA criteria.

AbstractIn the intensively farmed, homogenous agricultural landscape of the North China Plain, family graveyards form distinct cultural landscape features. In addition to their cultural value, these graveyards represent semi-natural habitat islands whose potential roles in biodiversity conservation and ecological functioning has remained poorly understood. In this study, we investigated plant species richness on 199 family graveyards of different ages and sizes. In accordance with biogeography theory, both overall and insect-pollinated plant species richness increased with area and age of graveyards. Even small graveyards show a strong potential for conserving local plant richness, and a mosaic of both large and small family graveyards could play an important role in the conservation of farmland biodiversity and related ecosystem functions. The launch of agri-environmental measures that conserve and create semi-natural habitats, in turn benefitting agricultural biodiversity and ecological functioning, has proven difficult in China due to the shortage of dispensable arable land. Given the great value of family graveyards as semi-natural habitats reflected in our study, we propose to focus preliminary efforts on conserving these landscape features as existing, widespread and culturally important semi-natural habitat islands. This would represent an effective, complementary policy to a subsequent re-establishment of other semi-natural habitats for the conservation of biodiversity and ecological functioning in agricultural landscapes.

This paper presents an analysis of the situation in which a two-wheeler (i.e. a motorcycle, where the term motorcycles includes scooters) falls over to the side and then successively slides; this typically occurs in road accidents involving this type of vehicle. Knowing the deceleration rate of the sliding phase allows the kinetic energy dissipated and the speed of the motorcycle just before the fall to the ground to be calculated. These parameters are very important in the analysis and reconstruction of accidents. The work presented in this paper was developed in two experimental test sessions on fully faired motorcycles which are mainly of the scooter type and widely used in urban areas. In the first session, sliding tests were carried out, with the speed in the range 10–50 km/h, on three different types of road surface. Analysis of the evidence allowed the dissipative main phases of motion of the motorcycle (the impact with the ground, the rebounds and the stabilized swiping) to be identified and some factors affecting the phenomenon to be studied. The coefficient of average deceleration was calculated using two typical equations. The second test session consisted of drag tests. In these tests, the motorcycle, which had previously laid on its side, was dragged for a few metres at a constant speed of about 20 km/h, while the drag force was measured. A comparison of the results obtained in these tests with those obtained in the sliding tests yielded very good agreement in the coefficients of deceleration.

Understanding long-term changes in precipitation and temperature patterns is important in the detection and characterization of climate change, as is understanding the implications of climate change when performing impact assessments. This study uses a statistically robust methodology to quantify long-, medium- and short-term changes for evaluating the degree to which climate change and urbanization have caused temporal changes in precipitation and temperature in South Korea. We sought to identify a fingerprint of changes in precipitation and temperature based on statistically significant differences at multiple-timescales. This study evaluates historical weather data during a 40-year period (1973–2012) and from 54 weather stations. Our results demonstrate that between 1993–2012, minimum and maximum temperature trends in the vicinity of urban and agricultural areas are significantly different from the two previous decades (1973–1992). The results for precipitation amounts show significant differences in urban areas. These results indicate that the climate in urbanized areas has been affected by both the heat island effect and global warming-caused climate change. The increase in the number of rainfall events in agricultural areas is highly significant, although the temporal trends for precipitation amounts showed no significant differences. Overall, the impacts of climate change and urbanization in South Korea have not been continuous over time and have been expressed locally and regionally in terms of precipitation and temperature changes.

AIM: This study aimed provides a checklist of cladocerans and also an evaluation of richness and species composition in the Federal District, Brazil. METHODS: Checklist of cladocerans was obtained evaluating data from the literature, from taxonomic collection (Elmoor-Loureiro's collection) and from fauna surveys conducted over more than three decades in different types of aquatic environments. RESULTS: The 57 water bodies studied showed 56 species, of which 14 are new records. The number of species contained in the list displayed corresponds to 85% of what was expected for richness estimators. The highest number of species was observed in the lentic water bodies (52), which also presented the specific composition of fauna (R = 0.110; p = 0.016), possibly because there were samples taken among the aquatic vegetation. According to our understanding, some species may be subject to local extinctions because they inhabit water bodies located exclusively in urban areas, which can lead to a decline in richness. CONCLUSION: Thus, the results of this study can assist in monitoring aquatic environments and in selection of new areas for surveys of cladocerans in the Federal District.

This study reviews the growth strategies and their effect on the efficiency and productivity of the microfinance sector of Pakistan. The sector needs to have adopted intensive growth strategy instead of extensive strategies of wide expansion in term of physical infrastructure and human resources, which had increased the financial sustainability risks for the credit constrain institutions. The sixdimension model of outreach used in this study also shows that the sector does not achieve the targets set forth for these micro finance institutes with respect to its active borrowers’ outreach. The sector has mainly focused the big cities and urban areas whereas the poverty levels are higher in rural areas. The government has also shown its interest by launching two different types of loan schemes. Among the three different types of institution, the microfinance banks dominate the sector.

The fauna of the longhorn beetles of ecoregion of Kremenetski Hory and the eponymous National Park was studied very poorly. In the most recent catalogue of Cerambycidae of Western Podillya it was listed only 13 species for the ecoregion. Including other sources, to date, it was known 17 species of the longhorn beetles. In the current study we identified 59 species of the longhorn beetles, 42 of which are reported for the first time for National Park «Kremenetski Hory» and the ecoregion in general. Under our proposed prediction the Cerambycidae species richness should reach 100-120 species. We also presented result of quantitative study of the longhorn beetles within different types of ecosystems of National Park «Kremenetski Hory». We revealed that 10 species are the most abundant on the studied territory.

AbstractIn this paper, an attempt has been made to analyse how the violence and abuse against elderly migrants in Monterrey, Mexico affects their health. For this research, 257 elderly Mexican migrants were surveyed in the Metropolitan Area of Monterrey during 2012 through 2013. The study found that the majority of elderly people migrate to urban areas in search of a better economic opportunity. Once in the city, they are absorbed into the informal economic sectors. Results indicate that most of these elderly people suffer physical, sexual and psychological violence, as well as neglect and financial abuse from their employer, relatives, clients and pedestrians, which has an adverse effect on their health. Elderly migrants reported numerous health problems, where many of them were suffering from different types of injuries, stress and depression, among others. This paper concluded that violence suffered by elderly migrants has a significant impact on their health.

The spatial representation by media is based on a series of material and ideational conditions structuring the journalistic profession and its public on a daily basis. Media are also actors taking part into the production of territories by mediatizing a “here” and “there” in which different types of news, institutional powers and cultural identities are portrayed. They are organized by a sum of geographical borders that they reproduce or cause to evolve. Over the past 20 years, media have accompanied the growth of western metropolises : The free daily newspapers circulated in large urban areas cutting across the mosaic of inherited institutional territories. However, does this necessarily mean that this press is able to overcome the territorial borders of the past ? The research based on the analysis of 20 Minutes Switzerland aimed at the French-speaking community shows that this medium is both included in bordered territories at the scale of cantons, regions and countries and also in an urban and transitional border space reorganizing these areas. Free dailies can be considered as a medium embedded in historically fragmented territories and the large urban regions of today. Les médias définissent une représentation de l’espace qui repose sur une somme de conditions matérielles et idéelles structurant au quotidien la sphère journalistique et son public. Par ailleurs, ils sont des acteurs de la production territoriale en médiatisant un « ici » et un « ailleurs » où s’organisent une actualité différente, des pouvoirs institutionnels dissemblables et des identités culturelles séparées. Les médias sont organisés par une somme de frontières géographiques qu’ils participent à reproduire ou à faire évoluer. Au cours des 20 dernières années, un média à accompagner l’essor des métropoles occidentales : les quotidiens d’information gratuits diffusés dans des régions urbaines chevauchant la mosaïque des territoires institutionnels hérités. Cela signifie-t-il pour autant que cette presse est en mesure de s’émanciper des frontières territoriales du passé˚? La recherche effectuée à partir du journal 20 Minutes Romandie montre que ce média s’inscrit, à la fois, dans des territoires clos de niveau confédéral, régional et cantonal, et dans une région urbaine frontalière transitionnelle rassemblant ces aires. La presse gratuite est un média situé dans la mosaïque territoriale du passé et dans les grandes régions urbaines d’aujourd’hui.
