“…In the species-focussed analyses the widespread, mainland Spialia sertorius was amalgamated with the Sardinian and Corsica endemic S. therapne and with the exceptional (probably relictual) eastern Mediterranean S. orbifer. The occurrence of preglacial and post-glacial relict populations seems to be the rule on Mediterranean islands (Habel et al 2009(Habel et al , 2010Dapporto 2010;). Clearly if native island Spialia populations are lost, they cannot be replaced by propagules with the same genotypes from the neighbouring mainland.…”

Biogeographical analyses are applied to skipper (Hesperioidea) presence/ absence data from the Western Mediterranean mainland and the three largest islands (Sardinia, Corsica and Sicily) in order to identify potential conservation issues. The analyses performed on species, both collectively and individually, indicate that regional species richness and occurrence in the Mediterranean zone are largely predicted by latitude and area but that islands have impoverished faunas. Several species, predicted to be present on these islands from logistic regression of their continental distributions, are actually absent. The number of species predicted to be present from logistic regression analyses for each island, closely matched the number of species predicted to occur in regional-focused multiple regression analysis. This suggests that missing species have been identified. When compared with species that occur in Sicily and Corsica, the missing species are shown to differ for ecological traits, mainly those linked to altitudinal tolerance. No ecological distinctions were disclosed for Sardinian skippers suggesting a mainly stochastic colonisation. These results, and those from an analogous study carried out on Papilionoidea, point to Hesperioidea having (i) overall more impoverished faunas on islands and (ii) being subject to stochastic or historical colonisation events more than Papilionoidea. Species not predicted to occur on islands based on their mainland distributions and ecological traits, are Electronic supplementary material The online version of this article (foci for conservation attention. However, as many species becoming extinct on the islands may be irreplaceable, all species, in particular the Sardinian ones, deserve to be conserved.

“…Future climate scenarios were taken from two global circulation models (GCMs) obtained from www.worldclim.org: the Community Climate System Model (CCSM) [64] and the Model for Interdisciplinary Research on Climate (MIROC) [65][66]. These GCMs differ in the reconstruction of several climatic variables and are well known to produce different outcomes for butterfly species [67][68]. For example, in hind-casting Mediterranean butterflies, the CCSM model projects narrower distributions at the last glacial maximum than does MIROC [65][66].…”

“…For each of these two GCMs, we considered two different representative concentration pathways (RCPs) [69][70][71][72][73], which are cumulative measures of human emissions of greenhouse gases from all sources expressed in Watts per square meter. These pathways were developed for the Fifth Assessment Report of the Intergovernmental Panel on Climate Change [67] and correspond to a total anthropogenic radiative forcing of RCP = 4.5 W/m 2 (low) and RCP = 8.5 W/m 2 (high) [72][73].…”

Climate change is predicted to alter the geographic distribution of a wide variety of taxa, including butterfly species. Research has focused primarily on high latitude species in North America, with no known studies examining responses of taxa in the southeastern US. The Diana fritillary (Speyeria diana) has experienced a recent range retraction in that region, disappearing from lowland sites and now persisting in two, phylogenetically disjunct mountainous regions. These findings are consistent with the predicted effects of a warming climate on numerous taxa, including other butterfly species in North America and Europe. We used ecological niche modeling to predict future changes to the distribution of S. diana under several climate models. To evaluate how climate change might influence the geographic distribution of this butterfly, we developed ecological niche models using Maxent. We used two global circulation models, CCSM and MIROC, under low and high emissions scenarios to predict the future distribution of S. diana. Models were evaluated using the Receiver Operating Characteristics Area Under Curve test and the True Skill Statistics (mean AUC = 0.91± 0.0028 SE, TSS = 0.87 ± 0.0032 SE for RCP = 4.5, and mean AUC = 0.87± 0.0031SE, TSS = 0.84 ± 0.0032 SE for RCP = 8.5), which both indicate that the models we produced were significantly better than random (0.5). The four modeled climate scenarios resulted in an average loss of 91% of suitable habitat for S. diana by 2050. Populations in the Southern Appalachian Mountains were predicted to suffer the most severe fragmentation and reduction in suitable habitat, threatening an important source of genetic diversity for the species. The geographic and genetic isolation of populations in the west suggest that those populations are equally as vulnerable to decline in the future, warranting ongoing conservation of those populations as well. Our results suggest that the Diana fritillary is under threat of decline by 2050 across its entire distribution from climate change, and is likely to be negatively affected by other human-induced factors as well.

“…Predictive distribution models (PDMs) have been increasingly used to visualize potential distribution areas of living entities such as birds (Manel et al, 1999;Brotons et al, 2004;Seoane et al,2004;Ortega-Huerta and Peterson, 2008), plants (Ray et al, 2011;Rameshprabu and Swamy, 2015), wild animals (Munguía et al, 2008;Ahmadi et al, 2013;Kramer Schadt et al, 2013), insects (Tognelli et al,2009;Habel et al, 2010;Dáttilo et al, 2012;Sobek-Swantet al,2012;Filz and Schmitt, 2015;Sánchez-García et al, 2015), reptiles and amphibians (Guisan and Hofer, 2003;Arntzen, 2006;Franklin et al, 2009) in conservation biology, biogeography and forest ecology. Those models have been also used in mapping vegetation communities (Lees and Ritman, 1991;Dymond and Johnson, 2002;Boyden et al, 2013), ecological land classification (Blasi et al,2000;Özkan et al, 2013;Grondin et al, 2014) and biodiversity (Özkanet al, 2016).…”

Aim: Methodology:Results: Interpretation:The fundamental information layers of ecosystem -based management plans are obtained by calculating, modeling and mapping of biodiversity. This study was carried out to calculate and map of landscape diversity in the Kuyucak Mountain District, in the transition zone of the Mediterranean region.Topographical diversity values of altitude, slope degree and radiation index for each cell (752.09 × 752.09 m) of Kuyucak Mountain District were calculated using Shannon Wiener, Simpson diversity, Renyi H and Rao indices. The index for each variable topographic map, which was prepared 2 using cellular values after the calculations was obtained by Geographic Information Systems.The maps illustrating diversities of topographical variables were prepared in order to obtain more accurate model -based distribution map of biodiversity.Climate, topography and soil properties play important roles on biodiversity. There are also significant relationships between landscape diversity and biodiversity. That is why it is important to prepare not only climatic, topographic and soil maps but also diversity maps as explanatory variables for modeling and mapping of biodiversity.
