“…For example, in the case of Sicily, the large cluster of type localities on Madonie mountains would be expected by the presence of an overlapping Italian Important Plant Area, and its presence is in line with the study of Bonanno and Veneziano (2016). Similarly, in Sardinia, Cañadas et al (2014) identified three micro-hotspots hosting more than the 20% of the 171 Sardinian endemic taxa, i.e., Supramontes, Iglesiente and Gennargentu regions. These three micro-hotspots are overlapped by a large number of type localities for endemic and narrow endemics species (Fig.…”

“…It is generally agreed that among the most pressing issues challenging the global conservation community is how to identify biodiversityrich areas and distribute limited resources between regions identified as priorities for biodiversity conservation (e.g., Cañadas et al, 2014;Wilson et al, 2006). However, biodiversity is a complex multifaceted concept that includes scales in space and time, and areas of high priority for conservation may be defined on the basis of habitat and species richness, endemism, genetic or phylogenetic diversity, the probability of species' extinctions or other indices (Ferreira and Boldrini, 2011;Li et al, 2015;Myers et al, 2000;Orme et al, 2005;Pavoine and Bonsall, 2011;Pouget et al, 2016;Schmeller et al, 2014).…”

A B S T R A C TWe conducted a GIS spatial analysis with the aim of providing the first quantitative large-scale overview of the distribution patterns of 1536 type localities (loci classici) of 1216 Italian endemic vascular plants and their relationship with a set of descriptive variables. Whereas some variables were used to model the presence-absence distribution patterns of the type localities for the whole set of endemics as well as for the subset of narrow endemics, others (e.g., presence inside or outside protected areas and Italian Important Plant Areas) were considered with the purpose of assessing potential assets or risks for conservation.The largest number of type localities was found within the Mediterranean biogeographic region (1134),http://dx

“…Unfortunately, it cannot be omitted that both in Sardinia and Corsica many fragile habitats and some endangered and endemic taxa are at risk of disappearance Cañadas et al, 2014). It is also noteworthy that the two islands are major touristic destinations in the Mediterranean, especially concerning beach tourism thus entailing an exceptional land use in coastal areas that, together with other natural and seminatural habitats, are also constantly threatened by other menaces such as recurring fires, exaggerated herbivorism, overexploitation of natural resources, increasing urbanization and the subsequent land degradation (Vacca et al, 2002;Delbosc, 2015).…”

This article provides a comparison of the vascular alien flora of Sardinia (Italy) and that of Corsica (France), both territories belonging to the Western Mediterranean biogeographic subregion. The study has recorded 598 (90 doubtful) alien taxa in Sardinia (18% of the total flora) while 553 (87 doubtful) in Corsica (17%); six are new report to Sardinia and 27 to Corsica. A total of 234 taxa are common to both islands. Neophytes are 344 taxa (68% of the total) in Sardinia and 399 taxa (73%) in Corsica. The invasive component includes 64 taxa in Sardinia (13% of the alien flora) and 99 taxa (21%) in Corsica, 33 of them common to both territories. The total 740 alien taxa of Sardinia and Corsica are included in 93 families; being Fabaceae the richest. The comparison of the biological spectrum reveals that phanerophytes (202 taxa, 40%) are the most represented in Sardinia and therophytes (149 taxa, 32%) in Corsica. A study of the geographical origin shows supremacy of the American element in Sardinia (170 taxa, 34%) and in Corsica (136 taxa, 29%). The majority of taxa arrived as a result of intentional human introductions, mainly for ornamental use (247 taxa, 49% in Sardinia; 208 taxa, 45% in Corsica). Seminatural, agricultural and synanthropic are the most occupied habitats. These data show the need for joint action to stem the increasingly worrying phenomenon of the alien flora in order to reduce the negative effects on natural habitats and native flora.

“…Such clustering regions refer to areas with highly concentrated high or low LST over a period of time and have strong effects on the surrounding ecology and environment. The formation of these areas is closely related to ecological factors and human activities (Cañadas et al, 2014). The classification of clustering regions (hot-spot analysis) relies on the integration of geographical location and spatial relationships and requires spatial statistical analyses and models (Peeters et al, 2015).…”

a b s t r a c tIdentifying factors that influence the land surface temperature (LST) of urban forests can help improve simulations and predictions of spatial patterns of urban cool islands. This requires a quantitative analytical method that combines spatial statistical analysis with multi-source observational data. The purpose of this study was to reveal how human activities and ecological factors jointly influence LST in clustering regions (hot or cool spots) of urban forests. Using Xiamen City, China from 1996 to 2006 as a case study, we explored the interactions between human activities and ecological factors, as well as their influences on urban forest LST. Population density was selected as a proxy for human activity. We integrated multi-source data (forest inventory, digital elevation models (DEM), population, and remote sensing imagery) to develop a database on a unified urban scale. The driving mechanism of urban forest LST was revealed through a combination of multi-source spatial data and spatial statistical analysis of clustering regions. The results showed that the main factors contributing to urban forest LST were dominant tree species and elevation. The interactions between human activity and specific ecological factors linearly or nonlinearly increased LST in urban forests. Strong interactions between elevation and dominant species were generally observed and were prevalent in either hot or cold spots areas in different years. In conclusion, quantitative studies based on spatial statistics and GeogDetector models should be conducted in urban areas to reveal interactions between human activities, ecological factors, and LST.
