The geometric documentation of the Greek cultural heritage sites participating in the TRIQUETRA project
No full textIn the light of threats including climate change, geological degradation and extreme weather conditions, the geometric documentation of cultural heritage sites plays a crucial role in their preservation. Photogrammetric techniques enable the production of highly accurate 3D models, orthoimages, and digital surface models (DSMs), which facilitate both site monitoring and conservation planning. This article presents the photogrammetric documentation of three archaeological sites in Greece, namely, the archaeological site of Aegina Kolonna, the Sunken City and the coastal cultural heritage of Ancient Epidaurus, as well as the sanctuary of Kalapodi. The geometric documentation of all three sites was conducted within the framework of the TRIQUETRA EU-funded project, through ground surveys and UAV-based photogrammetric techniques, either independently or in combination with underwater photogrammetry workflows, in order to capture the geometry of the cultural heritage sites and their surrounding environments. The produced results include 3D dense point clouds, 3D textured mesh models, DSMs and high-resolution orthomosaics. The generated datasets support detailed structural assessments, vulnerability analyses and risk assessment studies, providing a fundamental basis for protection efforts of the archaeological sites of interest
La difesa dei monumenti e lo studio della storia locale come baluardo di fronte alla trasformazione radicale delle città. Parigi, Bruxelles e Roma intorno al 1900
No full textIn the second half of the nineteenth century, European cities and rural areas underwent profound transformations, driven by the modernization of infrastructure and the industrialization of production processes. In response to these changes – and to the emergence of a nostalgic vision of the “vanished” city – the first voluntary associations dedicated to the protection of historical, artistic, and landscape heritage began to appear. This essay aims to explore the emergence and subsequent consolidation of these associations, which became active in major French, Belgian, and Italian cities in the study, preservation, and enhancement ofheritage elements (buildings, building complexes, neighborhoods, natural sites). Historic monuments and local identity became central themes in the public discourse of the period, while the historical study of the city enriched the evolving discipline of urban planning with a new dimension
The life cycle of a Brazilian Chlamisus leaf beetle on its Malvaceae host plants (Coleoptera: Chrysomelidae, Cryptocephalinae, Fulcidacini)
No full textThe Fulcidacini (Coleoptera: Chrysomelidae, Cryptocephalinae) is a group of beetles in which the females build a shelter of feces around their eggs and the hatched larvae maintain and expand this shelter with their own feces. Chlamisus Rafinesque, 1815 is the largest genus in the Fulcidacini, but immatures of only 25 of the ~400 recognized species have been reported. This paper presents, for the first time, the complete and detailed life cycle of a Chlamisus species. Adults were found feeding on Malvaceae (Hermannieae) in the semi-arid region of Brazil; some were collected for laboratory rearing and observation. Captive adults oviposited in individual containers. These eggs were kept in individual containers and after hatching, the larvae were fed and monitored daily until the adults emerged. The pre-imaginal period lasted 87.0 days, with four larval instars, each building on the fecal case from the previous instar. The period from egg fecal capsule to larval emergence was 14.75 days. The larval period lasted approximately 46.54 days. The period in the pupa fecal chamber lasted for 28.5 days. The active period of the immature represented about 45% of its total development time. This Chlamisus sp. appears to be monophagous in a broader sense, completing its development on related species and genera of Malvaceae (Hermannieae) and probably having more than one generation per year. The larvae exhibit a novel behavior in their case-construction, cutting off and discarding part of the case before pupation. The pupal chamber appears to be a novelty, mimicking the dried inflorescence of its Malvaceae host plants (in the genera Waltheria Linnaeus and Melochia Linnaeus)
A new species of Cephalotyphlus Coiffait, 1955 from Sardinia (Coleoptera: Staphylinidae, Leptotyphlinae)
No full textThe new species Cephalotyphlus supramontanus is described from Urzulei (eastern Sardinia, Nuoro province). The previously established synonymies of C. foroiuliensis (Pace, 1976), and C. bergamascus Pace, 1991 with C. vicetinus (Pace, 1975) are also discussed
First record of Urocerus augur from Bulgaria, with new occurrence data on U. gigas from collections and citizen science (Hymenoptera: Siricidae)
No full textThis study reports the wood wasp Urocerus augur (Klug, 1803) for the first time in Bulgaria and provides new records of U. gigas (Linnaeus, 1758), based on both collection material and citizen science observations. While U. gigas is more widespread, U. augur appears to be very rare in the country. All available occurrence data are compiled to present an updated overview of their distribution in Bulgaria. The species\u27 geographic ranges, elevational distribution, and seasonal activity are discussed. Photographs of U. augur and distribution maps for both species are included
Life cycle and phenology of Onthophagus vacca (L.) in Middle Atlas (Morocco): implications for conservation and ecosystem services (Coleoptera: Scarabaeidae)
No full textThis work investigates the life cycle and seasonal dynamics of the dung beetle Onthophagus vacca in Middle Atlas ecosystems in Morocco. This species is recognized for its crucial ecological role and was studied under controlled conditions to assess its developmental stages (egg, larva, pupa, adult) and seasonal abundance in relation to environmental factors. The results show that Onthophagus vacca has a short life cycle with peak activity in spring, which correlates with moderate temperatures and limited rainfall. The abundance of this species is higher in sites located at higher altitudes, where climatic conditions are more favorable. This study contributes to our understanding of the ecological requirements of Onthophagus vacca in Morocco and highlights the importance of its conservation to preserve the ecosystem services it provides, particularly in terms of soil fertility and excreta management in agricultural environments
Barcellona e la rete Eurocities: tra cooperazione urbana e articolazione politica (1986-91)
No full textAfter the Franco dictatorship, Barcelona emerged as a global city. The first democratic city councils opened up and projected the city into Europe and the world, launching a city brand symbolized by the 1992 Olympic Games. This initiative also created the opportunity for Barcelona to become a reference point for international municipalism. The city and the concept of municipalism are central elements in the political thought of Pasqual Maragall. As mayor of Barcelona, he promoted an international municipalist agenda that focused on cooperation in urban policies and the city’s presence on the international stage. This led to the promotion of city networks as tools for stabilizing new urban governance spaces and for engaging in the post-Cold War international relations system. This article analyzes how the creation of the Eurocities network fostered an experience of urban cooperation and political organization, proposing an inclusive approach for cities to participate in the European integration process
Kalapodi, Greece: the problem of frost at the archaeological site and the implementation of the TRIQUETRA programme
No full textIn central Greece, in today’s Fthiotis, where in antiquity Phokis bordered eastern Lokris and Boeotia, there is a sanctuary that is one of the most important of ancient Phokis. Systematic excavations were carried out in the sanctuary in the second half of the 20th century, under the direction of the German Archaeological Institute and they continue to this day. As part of the TRIQUETRA programme an integrated methodological model to protect archaeological remains at Kalapodi from frost is proposed. The TRIQUETRA project (EU HE research and innovation programme under GA No. 101094818) aims at creating an evidence-based assessment platform that allows precise risk stratification, and also creates a database of available mitigation measures and strategies, acting as a Decision Support Tool towards efficient risk mitigation and site remediation (Ioannidis et alii, 2024). This paper will present climatic data of Kalapodi together with materials analysis of the building materials of the sanctuary highlighting the frost problem
Description of new species of Spilophorus (Prospilophorus) Holm & Perissinotto, 2010 with revision of the subgenus (Coleoptera: Scarabaeidae, Cetoniinae, Cremastocheilini)
Full text linkDespite two revisions of the genus Spilophorus Westwood, 1848 having been published fairly recently, new findings and closer analyses have revealed the existence of more species than previously reported. A new species of the endemic African subgenus Prosphilophorus Holm & Perissinotto, 2010 has been discovered in Cameroon and is hereby described as S. (P.) superbus sp. nov. A series of new specimens of S. (P.) grandis Schein, 1949 has also been found in KwaZulu-Natal (KZN, South Africa), making it possible to confirm the type locality for this species in South Africa and necessitating the erection of a new species, S. (P.) holmi sp. nov. for the specimens from Tanzania, previously grouped under the former taxon. Finally, two female specimens housed in the Museum of Central Africa (MRAC, Tervuren, Belgium) and other specimens reposited in private collections and previously regarded as belonging to S. (P.) aurifer Westwood, 1874 are here recognized as a separate species and described as S. (P.) congoensis sp. nov. , on the basis of their comparativedifferences in dorsal ornamentation, sculpture and shape of the mentum. The genus appears to be of special significance for the biodiversity of the continent, due to its rather unique ecological characteristics of association with bird and ant aerial nests. The suggestion that species may represent highly specialized and isolated relicts, as highlighted in Holm & Perissinotto (2010), seems to be validated and strengthened by these findings
