Palaeoclimate has a major effect on the diversity of endemic species in the hotspot of mountain biodiversity in Tajikistan.
2021
AbstractIn a period of ongoing climate changes, identifying drivers of overall and endemic species diversity is a key element in constructing new ecological patterns and determining the main goals of conservation. Such studies are especially crucial if they concern biodiversity hotspot areas. In this study, we explore patterns and drivers of plant endemism (the proportion of endemic plant species to overall plant species richness; PE) in Tajikistan. We used three groups of climatic measures featuring the contemporary and glacial climates as well as climatic changes since the Last Glacial Maximum in the Pleistocene (LGM). To explore relationships between PE and climatic groups, and the most …
Hotspots e diritti: un binomio possibile?
2016
Il lavoro si occupa di verificare la compatibilità degli hotspots per migranti con il rispetto dei diritti fondamentali a livello sia costituzionale, sia convenzionale.
Consistent phenological shifts in the making of a biodiversity hotspot: the Cape flora
2011
Abstract Background The best documented survival responses of organisms to past climate change on short (glacial-interglacial) timescales are distributional shifts. Despite ample evidence on such timescales for local adaptations of populations at specific sites, the long-term impacts of such changes on evolutionary significant units in response to past climatic change have been little documented. Here we use phylogenies to reconstruct changes in distribution and flowering ecology of the Cape flora - South Africa's biodiversity hotspot - through a period of past (Neogene and Quaternary) changes in the seasonality of rainfall over a timescale of several million years. Results Forty-three dist…
The Foundation Seamount Chain: A first survey and sampling
1997
The Foundation Seamounts form a 1400 km-long chain on the Pacific plate from 32 °S, 127 °W to the Pacific-Antarctic spreading axis at 38 °S, 111 °W. Previously only known from sparse single-beam echosoundings and satellite altimetry, we present here the first multibeam bathymetric survey and geological sampling results. We confirm that the submarine topography correlates with the altimetry, and that the chain is volcanic rather than tectonic or microcontinental in origin. The chain can be divided up morphologically and geochemically into three section: (1) west of 125 °W large flat-topped volcanoes composed of incompatible-element depleted lavas ( ≈ 1) of a near-ridge origin with little or …
Soil geography and diversity of the European biogeographical regions
2013
For decades, soil geography has beenmainly a qualitative and descriptive discipline. There are nowtechnologies and mathematical tools available that allow formalizing soil geography in more quantitative terms. In this paper, the distribution and diversity of the soils of Europe are analyzed using GIS tools and pedodiversity algorithms. Soil data were taken from the European Soil Database (V2.0) and computed within the spatial framework of the Biogeographical Regions of Europe (BGRE) as defined by the European Environmental Agency (EEA) on the basis of climate and vegetation. The results obtained show the soil assemblages, including dominant soils and endemic and non-endemic soil minorities,…
Džona F. Hota nākotnes metafizikas formulēšanas problemātikas analīze
2016
Bakalaura darbā tiek analizēta Džona F. Hota nākotnes metafizikas skaidras un formālas aprakstīšanas problemātika. Lai to izdarītu, vispirms tiek analizēti galvenie nākotnes metafiziku veidojošo konceptu ietekmes avoti – Pjēra Teijārda de Šardēna un Alfrēda Norta Vaitheda uzskati. Tie pēc tam tiek izmantoti, lai saprastu galvenos Džona F. Hota ar nākotnes metafiziku saistītos filozofijas un teoloģijas elementus. Šie Hota uzskati tiek izmantoti, lai noteiktu nākotnes metafizikas pamataprises. Pēc tam darbā tiek analizēti šīs koncepcijas skaidras formulēšanas problemātiskie aspekti un tiek noskaidrots, kādā mērā nākotnes metafizika var un kādā nevar tikt saprasta kā metafiziska sistēma, un, k…
Plant landscape and phytodiversity in the archeological area of Segesta (NW Sicily)
2018
In the system of Sicilian archaeological parks, the area of Segesta - an ancient city of western Sicily referring to the Carthaginian eparchy, - represents, together with Selinunte, Erice and Mothia, another integrated hotspot of biodiversity and archeaology. The current plant landscape is strongly influenced by a millenary anthropic transformation. There are no residual expressions of the original plant covering that, with reference to the environmental potential of the area, can be traced back to the evergreen Mediterranean forest dominated by Quercus ilex, presently only sporadically occurring in the area of the ruins, together with other species related to associations and upper syntaxa…

Spatiotemporal hotspots analysis for exploring the evolution of diseases: An application to oto-laryngopharyngeal diseases
2013
Abstract View references (14) This paper presents a spatiotemporal analysis of hotspot areas based on the Extended Fuzzy C-Means method implemented in a geographic information system. This method has been adapted for detecting spatial areas with high concentrations of events and tested to study their temporal evolution. The data consist of georeferenced patterns corresponding to the residence of patients in the district of Naples (Italy) to whom a surgical intervention to the oto-laryngopharyngeal apparatus was carried out between the years 2008 and 2012
