Questing abundance of adult taiga ticks Ixodes persulcatus and their Borrelia prevalence at the north-western part of their distribution
2020
Background Because ixodid ticks are vectors of zoonotic pathogens, including Borrelia, information of their abundance, seasonal variation in questing behaviour and pathogen prevalence is important for human health. As ticks are invading new areas northwards, information from these new areas are needed. Taiga tick (Ixodes persulcatus) populations have been recently found at Bothnian Bay, Finland. We assessed seasonal variation in questing abundance of ticks and their pathogen prevalence in coastal deciduous forests near the city of Oulu (latitudes 64–65°) in 2019. Methods We sampled ticks from May until September by cloth dragging 100 meters once a month at eight study sites. We calculated a…
Izmaiņas Latvijas piekrastes ainavā 20.-21. gadsimta mijā un mūsdienu izaicinājumi
2013
Dažādi faktori ietekmē piekrastes zonas attīstību gan pasaulē, gan Latvijā, kā rezultātā notiek izmaiņas ainavas struktūrā un tās spējā nodrošināt sabiedrībai nepieciešamos resursus. Promocijas darbā Latvijas piekrastes ainava ir pētīta atšķirīgos mērogos un kontekstos: i) izmaiņas jūras piekrastes ainavas struktūrā un tās ietekmējošie faktori ir vērtēti visas Latvijas piekrastes zonā; ii) potenciālā vēja enerģijas ražošanas jūrā ietekme uz ainavas vizuālo struktūru ir novērtēta unikālajā Baltijas jūras stāvkrastu zonā; iii) pludmales ainavas kā rekreācijas pakalpojuma nodrošinātāja nozīmīgums ir noskaidrots četrās atšķirīgās Latvijas pludmalēs. Darbs ir transdisciplinārs, jo tajā ir izmant…
Funzioni e percezioni del territorio. L’esperienza del GAC «Il sole e l’azzurro: tra Selinunte, Sciacca e Vigata»
2018
Il presente contributo s’inserisce nel dibattito sulla riorganizzazione territoriale dell’Italia a partire da progettualità e voca- zioni di sviluppo condivise dai territori. In particolare, viene analizzato il sistema di governance e attività che, in seno alle politiche comunitarie, specie a quelle condotte con approccio LEADER, è stato proposto dal GAC «Il Sole e l’Azzurro: tra Selinunte, Sciacca e Vigata». I GAC (Gruppi di Azione Costiera) sono partenariati pubblico-privati che, con un approccio bottom-up, sono preposti a valorizzare il comparto ittico e, più in generale, gli assets costieri dei territori. Attraverso un approccio geogra co ed etnogra co, declinato mediante la conduzione …

Investigations into the development and role of a Mediterranean intertidal bioconstruction for coastal conservation: the Vermetid Reef
2017
Vermetid reefs are intertidal biogenic habitats created by a dense aggregation of mollusks, frequently cemented by calcareous algae, and are typical of sub-tropical and warm–temperate rocky shores. These bioconstructions are valuable key-habitats of the coastal zones, increasing their productivity and biological value. In the Mediterranean, the main vermetid reef builders belong to the genus Dendropoma and are associated to encrusting coralline red algae. These organisms are ecosystem engineers protected under international European Legislation, although vermetid reef conservation is limited by a lack of biological and ecological knowledge. The two-way interactions between biota and the phy…

Potential effects of transgenic cotton on soil ecosystem processes in Vietnam.
2008
This chapter concentrates on the potential effects of transgenic cotton on the soil ecosystem of three major cotton growing areas in Vietnam: the coastal lowlands region, the central highlands (eastern and western Truong Son Mountain Range) and the south-eastern region. Soils in these three regions are very different, so it will be necessary to assess the effects of transgenic cotton on typical soils from all three regions. The soils in the south-eastern region are Luvisols, Andosols and Acrisols. In the central highlands, the soils are mainly Luvisols, Rhodic Ferrasols and Haplic Acrisols. The soils in the coastal lowlands region are mainly delta soils, consolidated occasionally by grey li…
Sisubiotus hakaiensis sp. nov. (Tardigrada, Macrobiotidae), a new tardigrade species from Calvert Island (British Columbia, Canada)
2022
Tardigrades reports from British Columbia (Canada) trace back to 1908 and numerous species have been recorded from this region, despite the relatively few published sampling studies. We describe by integrative taxonomy (light microscopy morphology, morphometrics, and DNA sequencing) a new tardigrade species, Sisubiotus hakaiensis sp. nov. from the British Columbia central coast. The new species has been found in moss collected from a vertical rock outcrop near the Hakai Institute Calvert Island Field Station. Sisubiotus hakaiensis sp. nov. differs from all the other known species in the genus by the presence of a labyrinthine layer inside the egg process walls, whereas no consistent differe…

2017
La scheda è un estratto del contributo dell’Unità di Ricerca di Palermo nel PRIN “Re-cycle Italy” al seminario internazionale “Progetto di riciclo e infrastruttura-zione del territorio. "Selezione, manutenzione, nuovi modelli”, organizzato dall’Unità di Ricerca del Politecnico di Milano il 26 e 27 febbraio 2015. The postcard is an extract of the Palermo Research Unit’s contribution to the “Re-cycle Italy” National Interest Research Project at the international seminar “Recycling and Infrastructure Plan for the Territory. Selection, Maintenance, and New Models”, organized by the Politecnico di Milano Research Unit on the 26th and 27th February 2015.
Les types de temps associés aux risques d’inondations et d’érosions en Camargue : éléments de diagnostic et de prospectives pour le 21e siècle (1993-…
2010
Les fortes surcotes marines et les fortes vagues sont les principaux aléas météo-marins associés aux risques de submersion et d’érosion du littoral camarguais. Sur la période 1993-2002, une forte fréquence mensuelle de très hautes surcotes marégraphiques est généralement associée à une forte fréquence de très hautes vagues. Ces deux phénomènes locaux se produisent principalement lorsqu'une dépression autour du Golfe de Gascogne est associée à des hautes pressions sur l’Europe Centrale. La fréquence mensuelle de ce type de temps nous renseigne sur la probabilité d’occurrence de fortes surcotes marégraphiques et vagues en Camargue. Au 21e siècle, la fréquence du type de temps associé aux plus…
