Abstract Background The inventory process is the first method to protect and safeguard animal biodiversity. This study carries out a quantitative and qualitative inventory of terrestrial gastropods at three sites in Skikda province (north-eastern Algeria). The relationship between terrestrial gastropod diversity and soil physicochemical factors was investigated using statistical analyses. Results The inventory data reveals the presence of four families and eight species showing varied predominance rates of Cornu aspersum species according to each site in the city of Skikda (Azzaba 53.88%; Ben-Azzouz 56.12%; El-Hadaiek 37.92%). The maximal specific richness was registered in the El-Hadaiek site (seven species), and the highest mean richness was noted in the Ben-Azzouz site (392 individuals). Of the eight gastropod species identified, three species (Cornu aspersum, Cantareus apertus and Rumina decollate) were classified as constant species. The Shannon–Weaver diversity and equitability indices vary by site. Conclusion The presence of certain species in one site and their absence in other sites, as well as the variation in ecological indices, could be attributed to the effect of soil-physicochemical factors.

On June 7, 2018, a sub-mesoscale anticyclonic eddy induced by the wind (north-east) was registered on the shelf in the area of the city of Gelendzhik. With the help of field multidisciplinary expedition ship surveys, it was shown that this eddy exists in the layer above the seasonal thermocline. At the periphery of the eddy weak variability of hydrochemical parameters and quantitative indicators of phytoplankton were recorded. The result of the formation of such eddy structure was a shift in the structure of phytoplankton – the annual observed coccolithophores bloom was not registered.

This work concerns Vicenza, a city located not far from Venice in the north-east corner of Italy, and it specifically refers to an area situated on the outskirts of the city’s urban fabric between the perimeter of its ancient walls and the banks of the Bacchiglione river, in the shadow of the abandoned monastery of St. Biagio. The idea of restoring that physically and socially degraded area of the city of Vicenza has long been the object of discussion on the part of local authorities. Once intimately linked to the city’s historic center, the area gradually lost its functional and social identity becoming first a parking lot and then equipped as a city warehouse. The intent to regenerate the area and the observation that the relationship between the city and its river is constantly refused, or delayed, lead to recognize in the long edge of the area a unique meeting opportunity which allows to repair the water-city association, recuperating rituals and connections from the past. The municipality is presently planning on pursuing a qualitative restoration of the area which will be used for social and cultural enrichment. The final part of the current work outlines some proposals that were developed during the Architectural and Urban Composition 2 course recently offered by the Department of Civil, Environmental and Architectural Engineering of the University of Padua (Italy).

The biodiversity and quality of subterranean waters were comparatively studied in the Tarf plain near Oum-El-Bouaghi and in the Ksar S’bahi in Oum-El-Bouaghi, in North-eastern Algeria. For this purpose, physicochemical and faunistic analyses were carried out on the water of ten stations located in the area of Tarf, and thirteen in the area of S’bahi. In the wells of Tarf, the average stygobiologic diversity was relatively high in the wells located upstream the dumping site from the city where the groundwater presented low contents of nitrates and orthophosphates. In contrast, the wells located in the spreading zone of Tarf wastewaters were characterized by the scarcity or the absence of stygobic species; in these latter wells, the water was highly polluted. It was rich in nitrates, nitrites, ammonium, and the conductivity was rather high. In the area of S’bahi, the faunistic inventory recorded ten species, some of which were living in hot springs. The subterranean water was highly mineralized. In the two studied areas, biodiversity decreased when well water was locally polluted.

Abstract El Kala is a city on the edge of eastern Algeria, located in an exceptional natural landscape, classified as a world biosphere reserve in 1990 by UNESCO. The diversity of nature within the domestic space leads to research and study its place and value for the inhabitants and encourages to think about how to qualify the relationship between inhabitants and nature through the domestic space. This study is based on a biophilic approach, adapted to the architectural scale, based on a landscape and architectural analysis. The results obtained show that the observed biophilic design is only a means to build a relationship with nature by the inhabitants. The objective of this article is to highlight the contribution of the biophilic approach in determining the behaviour of the inhabitants of the city of El Kala.

This article examines the history of the disappeared Russian settlement-fortress, which refers to the period XVI-XVIII centuries. In earlier sources the city was called the redoubt of the Terek, the Terek fortress, sometimes there is a shorter name -Grater. Later they began to use the name Terek the city, represents the city and fortress near the mouth of the Terek, not far from the now not-existing of the river Tyumenka. In the modern period is the territory of the left Bank of the Old Terek to the North-East of the city of Kizlyar, Republic of Dagestan. Criticized the attempts to identify the history of the two fortresses: Walled town and Floats, as well as their role at the initial stage in the formation of Russian population of Dagestan. Characterized by the influence of the process of renewal of the Cossacks in military servicemen estate on the historical development of areas North-Eastern Caucasus. Attention is paid to issues such as the existence of different versions of the city name, the location where divergent opinions of researchers. Emphasis is placed on the role of the Terek city as the southern Outpost of the Russian state, the conductor's Caucasus policy on the North-Eastern Caucasus. The analysis of the problem, which allowed us to consider the integration of the provincial regions in the periphery of the Russian state in the South of the country, and analyzed the development of reference points to spread the influence of Russia in the XVI-XVII centuries.

The City

The commercial dynamics that the city of Annaba has experienced in recent decades, due to social and economic development and market liberalization, have changed its urban and architectural heritage. This city, located in north-eastern Algeria and created before the tenth century, has seen many civilizations and dynasties pass by. Every civilization has left behind traces that time has sometimes taken care of protecting them, to bequeath us or erasing them completely. This heritage wealth testifying and telling the story of our ancestors' past, unfortunately, began to lose its value and originality after the transformations and modifications that took place in the old residential buildings inherited from two opposing cultures by integrating new forms of commercial activities. The objective of this communication is to analyse and measure the evolution of these mutations, with a focus on the ancient colonial areas of the city of Annaba where the phenomenon is most pronounced.

AbstractIn the last three decades of the twentieth century, the relationship between the city and rural areas in central and north-eastern Italy was a much-debated issue particularly with regard to the existence of a macroregion (the ‘Third Italy’) where a new model of economic development was flourishing. Social scientists and politicians stressed the specific territorial organization of the phenomenon, marked by finely integrated urban and rural environments. Even today, this interconnection is sometimes considered in public discourse not only as characteristic of a national Italian identity, but also as a model for more sustainable social organization.

Abstract. Hichem K, Ramzi H, Djemoi M. 2019. Biodiversity and distribution of groundwater fauna in the Oum-El-Bouaghi region (Northeast of Algeria). Biodiversitas 20: 3553-3558. This study concerns the aquatic fauna of wells and springs in north of the city of Oum El Bouaghi, in the western part of the Tamlouka plain, north-eastern Algeria. 16 wells and two springs were selected and a seasonal sampling of the aquatic fauna was carried out from September 2017 to May 2018, covering periods of high and low water. Two types of traps were used: the phreatobiological net and baited traps. The composition of fauna was found to be 26 taxa and 6617 individuals, dominated by Crustaceans 47% followed by insects and shellfish 23% for each. Only one stygoby species was collected mainly: Pseudoniphargus djemoi.

While COVID-19 has unleashed waves of reverse-migration from the cities back to the hometowns due to economic and physical uncertainties that accompanied the pandemic, queer people from the North-Eastern Region of India choose to stay in the cities. Defying the reverse-migration trend, they choose the freedom that the city gives them over the prejudice of their hometown toward their sexuality. This paper will theorize how pandemic affects and at the same time affirms queer sexualities This paper will re-interpret metronormativity in the context of North-East queer people and will co-opt Judith Halberstam’s theory while at the same time reworking it to fit the local context of queer North-East. Unlike Halberstam’s theory that the metro offers a continuum of free existence to the queer people, this paper will examine certain queer narratives both online and through interviews in order to understand how the city offers not a “freer” existence ( in the sense that freedom is given and implied upon) but rather a relatively anonymous existence which allows them to live freely in anonymity but never silent. It will problematize the concept of home and space and how queer subjectivities are (un)formed depending upon certain variables that the home offers which eventually affects queer existence. This existence will then juxtapose with Kosofsky’s “gesture of silence” of the home and the closet and in doing so, it will attempt to understand North East queer’s preference for the danger of COVID 19 and the “insecurities” of the city over the “security” of home.

The contiguous United States (CONUS) harbor a significant non-native species diversity. However, spatiotemporal trends of some groups such as terrestrial gastropods (i.e., land snails and slugs) have not been comprehensively considered, and therefore management has been hindered. Here, our aims were to 1.) compile a dataset of all non-native terrestrial gastropod species with CONUS occurrence records, 2.) assess overarching spatiotemporal patterns associated with these records, 3.) describe the continental origin of each species, and 4.) compare climatic associations of each species in their indigenous and introduced CONUS ranges. We compiled a georeferenced dataset of 10,097 records for 22 families, 48 genera, and 69 species, with > 70% of records sourced from the citizen science database iNaturalist. The species Cornu aspersum Müller, 1774 was most prevalent with 3,672 records. The majority (> 92%) of records exhibit an indigenous Western European and Mediterranean distribution, with overlap in broad-scale climatic associations between indigenous and CONUS ranges. Records are most dense in urban metropolitan areas, with the highest proportion of records and species richness in the state of California. We show increased prevalence of non-native species through time, largely associated with urbanized areas with high human population density. Moreover, we show strong evidence for a role for analogous climates in dictating geographic fate and pervasiveness between indigenous and CONUS ranges for non-native species.
