Paysage et risque sanitaire - Le cas de l'echinococcose alvéolaire. Approche multiscalaire
2005
Echinococcus multilocularis is a parasite of public health importance causing the fatal zoonotic disease alveolar echinococcosis. The parasite's eggs are dispersed in the environment through the fox faeces. Epidemiological issues associated with the disease led to the monitoring of the endemic status in foxes in France and in Europe. Fox faeces collected in the field were tested for the presence of the parasite and assembled in a georeferenced database. GIS-assisted analysis investigated relationships between landscape characteristics and potential risk. Three scale levels were successively explored. In the french Doubs département located in a high endemicity area, binary logistic regressi…
Modes of Religiosity in Iberian Iron Age Caves: Religious Behaviour and Sensorial Experience
2021
The Iberian Iron Age caves are defined as a specific model of sacred space. First, from a territorial perspective, they are identified as liminal spaces where the collective participation, integration and the sense of belonging is reinforced. And secondly, as multisensory contexts, where different ritual practices, highly symbolised, are performed. These spheres, cut off from the well-known and daily scenarios boost the sensory hypersensitivity, strengthened by the connection between the senses and the natural scenario. This paper is guided by the theory of religiosity modes, developed by H. Whitehouse, with the purpose of a better understanding of the ritual practices that were carried out…
Territori locali. L’efficacia degli strumenti di governo dei paesaggi in transizione
2019
Si spopolano alcune delle aree deboli nel Paese. Le strumentazioni disponibili per la comprensione dei fenomeni di declino non sembrano in grado di cogliere appieno le specificità territoriali. Le attenzioni dei decisori alle tematiche sociali ed economiche sono proposte come prioritarie mentre la cura delle caratteristiche ambientali e culturali sono ancora oggi percepite come vincoli. Economia e sostenibilità culturale ed ambientale restano separate nella prevalenza dei casi e ciò determina l’inefficacia delle politiche di tutela e valorizzazione delle risorse in gioco. Le discipline economiche e quelle paesaggistiche dal punto di vista della ricerca possono essere integrate, mentre l’ana…
Dry-stone architecture

The essay describes the process of typification of rural products and cultural objects related to the commodification of Pantelleria as rural and touristic landscape.
Walory przyrodnicze pasa autostrady A-4 na terenie Parku Krajobrazowego Góra Świętej Anny w województwie opolskim
2014
Do budowy opolskiego odcinka autostrady A-4 przystąpiono latem 1997 r. Niedługo po rozpoczęciu budowy zaczęły się ostre protesty organizacji ekologicznych. Kością niezgody stał się jej odcinek przecinający Park Krajobrazowy Góra Świętej Anny, bezpośrednio sąsiadujący również ze ścisłym rezerwatem przyrody Ligota Dolna, chroniącym rzadką roślinność ciepłolubną. W latach 2011-2013 na terenie pasa drogowego autostrady A4 przechodzącego przez teren Parku Krajobrazowego Góra Świętej Anny w województwie opolskim przeprowadzono szczegółowe badania mikologiczne, geobotaniczne, florystyczne i faunistyczne. Na tym odcinku autostrady stwierdzono występowanie licznych rzadkich i chronionych gatunków gr…
The shape of the liquid plain: sicilian salt flats
2019
This paper analyzes the salt flats as a place for the mixing of knowledge and experiences that originate and substantiate life: from the application of physical, chemical and biological principles to produce salt, to economic laws to regulate sales and trade, to aspects socio-anthropological aspects underlying the life of the communities that worked in production. A patrimony of material and immaterial overlaps, generated by the redesign of a segment of territory with physical and positional characteristics median between sea and land, and in which man strives to obtain fundamental resources for his livelihood. Given the complex moment of crisis and gradual abandonment that these particular…
Salt exploitation, communication routes and territory during the Iron Age around the Cabriel river valley
2020
La sal era un recurso fundamental en la economía de las sociedades antiguas y cada vez tenemos más datos sobre su aprovechamiento y explotación durante la Edad del Hierro en ámbito peninsular. La comarca de Requena-Utiel, en el interior de la provincia de Valencia, presenta la mayor abundancia de salinas continentales históricas del territorio valenciano. Por otro lado, en La Manchuela conquense se localiza la importante mina de sal de Minglanilla-La Pesquera. El hallazgo de material arqueológico ibérico en algunas de estas explotaciones sirve como punto de partida para analizar sus características y ver cómo pudieron quedar integradas en el patrón de asentamiento, así como en una densa red…
Bryophyte diversity in semi-natural grasslands : the effects of habitat quantity and quality
2015
Edeltäneiden vuosisatojen maatalouskäytännöt loivat elinympäristöjä, joihin tänä päivänä viitataan perinnebiotooppeina. Siirtymä moderniin maatalouteen on muiden maankäytön muutosten ohella vähentänyt näitä biologisesti, kulttuurisesti ja sosiaalisesti arvokkaita elinympäristöjä murto-osaan entisestä. Perinnebiotoopeille tyypillinen avoimuus, vähäravinteisuus ja säännölliset häiriöt tekevät niistä biologisesti monimuotoisia elinympäristöjä. Perinnebiotooppien pinta-alan pienenemisen ja pirstoutumisen seurauksena on ollut useiden lajien uhanalaistuminen. Jäljellä olevien perinnebiotooppien laatua uhkaa etenkin hoidon riittämättömyys. Sammalet ovat kooltaan pieniä ja ekologialtaan riippuvaisi…
Towards a framework for assessment and management of cumulative human impacts on marine food webs
2015
Effective ecosystem-based management requires understanding ecosystem responses to multiple human threats, rather than focusing on single threats. To understand ecosystem responses to anthropogenic threats holistically, it is necessary to know how threats affect different components within ecosystems and ultimately alter ecosystem functioning. We used a case study of a Mediterranean seagrass (Posidonia oceanica) food web and expert knowledge elicitation in an application of the initial steps of a framework for assessment of cumulative human impacts on food webs. We produced a conceptual seagrass food web model, determined the main trophic relationships, identified the main threats to the fo…
The Role of Excited Oxygen Molecules in the Formation of the Secondary Ozone Layer at 87 to 97 km
2018
The secondary ozone layer is located at elevations of 87 to 97 km in the upper mesosphere – lower thermosphere. It overlaps with the ionospheric D-layer. Daytime intensive UV radiation is dissociating O2 molecules to O atoms and photoexcitating O2 molecules up to 11.07eV level. Ozone photolysis between the wavelengths of 118.7–121.6 nm produces three oxygen atoms from one ozone molecule. Collision reactions of O2(B3 Σu —) and O2(X3 Σg —, υ≥26) with O2(X3 Σg —, υ=0) produce additional oxygen atoms. The number of oxygen atoms is maintained at such a high level that a small but significant ozone concentration survives. UV radiation weakens radically during the night. The number of O atoms show…
