La Araña toro, Macrothele calpeiana, repeatedly imported to Germany (Araneae: Macrothelidae)
Get PDFMacrothele calpeiana (Walckenaer, 1805) is one the largest and most noticeable spiders that frequently “hitchhikes” with ornamental plants, a major vector for alien species, to areas outside its natural distribution. Two further imports of this species are presented herein, which were both found in Germany (Central Europe). While one specimen has been imported with an olive tree, the other spider was found in a potted citrus tree from Andalusia. The olive tree supposedly originates from Crete, for which no records of M. calpeiana are currently known. Both records probably represent only a small percentage of the specimens recently introduced To Germany (and Central Europe) by ornamental tree trade, as several postings on online spider boards and press articles suggest
Shore fly (Diptera: Ephydridae) communities from Ria de Aveiro, with new records for Portugal
No full textSaltmarshes are considered one of the most productive habitats in the world and exhibit a spatial zonation of its vegetation, from the intertidal flats to the seawall or dunes providing habitats to specific invertebrate assemblage adapted to regular submergence by seawater, and the resulting high soil salinity. These ecotones are essential to support coastal food webs and in providing nursery areas, for fish, crustaceans, and birds. Ria de Aveiro costal lagoon has been the focus of considerable research, but despite being part of Nature 2000 network, and being a Long-Term Ecological Research (LTER) site, insects have been systematically neglected. In this work we present new shore flies (Ephydridae) records from Ria de Aveiro saltmarshes, Portugal. Field collections were carried in seven locations along Ria de Aveiro saltmarshes areas by sweep-netting the dominating halophyte vegetation in September 2020. A total of 283 Ephydridae specimens from 8 genus and 17 species were collected. From these, 9 species are new records for Portuguese territory, 3 of them to the Iberian Peninsula. This work contributes to increase the dipterological knowledge regarding Ephydridae diversity in southern Europe, and to identify potential halophyte plant pests since several Ephydridae species are phytophagous
Taxonomic notes on some species of genus Charopus Erichson, 1840 in the Mediterranean Region (Coleoptera: Cleroidea, Melyridae, Malachiinae)
Get PDFThe results of the study of several hundred specimens of the genus Charopus, preserved in public and private collections from the Mediterranean region are here presented. For C. rotundatus Erichson, 1840 the neotype is here described. C. nitidus Küster, 1849 stat. rest. and C. multicaudis Kiesenwetter, 1866 stat. rest. are resurrected from synonymy with C. rotundatus and regarded as valid species. For C. nitidus Küster, 1849 stat. rest. a neotype is designated and described. Charopus varipes Baudi di Selve, 1872 stat. rest. is resurrected from synonymy with C. pallipes (A.G. Olivier, 1790) and regarded as a valid species. Elements for identification of the above mentioned species are provided in the form of comparative tables, and distributional data; list of known localities are also supplied. The distributions of Charopus apicalis Kiesenwetter, 1859, C. concolor (Fabricius, 1801) and C. flavipes (Paykull, 1798) are also briefly discussed. The new synonymy Cyrtosus (Oogynes) reitteri Abeille de Perrin, 1890 = Charopus crassicornis Wittmer, 1975 is proposed. A partial key to known males of Western Palaearctic species is also provided
A new subgenus with three new species of Agrotis from New Guinea (Lepidoptera: Noctuidae)
Get PDFFollowing the examination of museum holdings and recently collected material of noctuid moths from New Guinea, the new subgenus Papuagrotis Vink & Zilli subgen. n. of Agrotis Ochsenheimer, 1816 is described. This is found to consist of at least three montane species new to science that are herein described also, namely Agrotis (Papuagrotis) habbemae Vink & Zilli sp. n., A. (P.) bintangus Vink & Zilli sp. n. and A. (P.) minutus Vink & Zilli sp. n. Characters and relationships of the group with respect to other Agrotis s.l. are reviewed and briefly discussed
Subjects, effects, and urban practices of temporary populations. The case of Rome
No full text The object of the research are temporary populations in urban contexts. Various forms of temporary dwelling are analysed in the literature on urban studies, such as those related to tourism, study, work and lifestyle migration, but they are treated mainly separately. Despite the strong differences between these groups, I propose temporariness as a dimension that connects them, in a macro-category that can be defined as temporary populations. Through quantitative and qualitative methods, I present data sources, numerical estimates, socio-economic characteristics, and spatial trends of this category, in the specific case study of Rome. These data and analytical methods are useful to discuss the impact of these groups on housing, economic and social dynamics and, more generally, on the city’s development model
La questione nera e l\u27antisemitismo.: La genesi contradditoria dell\u27analisi comunista sul razzismo.
No full textIl saggio punta a ricostruire la genesi dell’analisi su razzismo e antisemitismo come fenomeni globali da parte dell’Internazionale Comunista, prendendo le mosse da due casi specifici: la cosiddetta “questione nera” negli Stati Uniti d’America e la diffusione ed evoluzione dell’antisemitismo in Europa. Gli autori individuano il ruolo che nella stampa e in alcuni documenti prodotti dal Comintern viene attribuito al così detto processo di “razzializzazione del conflitto sociale e politico”. Tale processo sembra essere infatti alla base tanto della tradizione razzista coloniale otto-novecentesca quanto di quella propria del progetto imperiale nazista
Contribution of geographic information system to improve the insurance management of natural disasters in Algeria case study: the City of Batna
No full textIn recent years, the frequency of natural disasters has increased all over the world, including in Algeria. In the last decades Algeria has been marked by very largescale natural disasters: floods, landslides and earthquakes, which have caused considerable material damage and loss of life in view of the extent of the damage caused by natural disasters, the public authorities have decided to set up a special insurance system (CatNat ) based on the obligation to insure against the effects of natural disasters, in order to lighten the burden on the State in terms of reparations. This insurance was created in 2004 following damage caused by the floods in Bab El Oued and the earthquake in Boumerdes in2001 and 2003 respectively. The increase in natural disasters and thus in the cost of claiming compensation encourages insurers to participate in the recovery and reduction of natural risks by improving their insurance management. The applications of Geographic Information Systems (GIS) to insurance management are numerous; and they allow, among other things, insurers to segment their pricing and to specialise the vulnerability of their insurance portfolios. Insurers support their management on natural risk, exposure and liability cards. Geographic information becomes crucial for insurers. This paper talks about clarified the role of insurers in the management of natural risks and how to promote better insurance management through the integration of geographic information system in the city Batna
An exceptional influx and successful breeding of Pantala flavescens on the Island of Malta (Maltese Archipelago) (Odonata: Libellulidae)
Get PDFPantala flavescens (Fabricius 1798) appeared in unprecedented numbers in summer and autumn 2020 on the island of Malta. Several males were observed holding territory over largely bare, small bodies of water, mostly at Chadwick Lakes and Fiddien. Breeding activity was witnessed several times and 128 exuviae were found of which 124 were collected
Il Comintern e l\u27Europa occidentale (1919-1935)
No full textPer l’Internazionale comunista, il ruolo dell’Europa occidentale fu centrale fin dall’inizio. Particolarmente significanti furono le esperienze del Segretariato latino guidato da Humbert-Droz nel 1926-28, dell’Ufficio per l’Europa occidentale (web) fondato nel 1927 e guidato da Dimitrov dal 1928 e del Segretariato per l’Europa centrale, anch’esso guidato da Dimitrov dal 1934. Queste esperienze collegarono lo sviluppo dei partiti comunisti occidentali agli eventi complessivi del Comintern e allo stesso tempo permisero a questi partiti di contribuire all’evoluzione della linea generale, fino alla svolta del singolo fronte antifascista nel 1934-35
