“…With appropriate cost assignment for movement of target species, LCP shows likely dispersal corridors Wang et al, 2009). To generate cost layers for LCPA, we translated suitability values from ENM into cost by assuming that habitat suitability should have a similar cost to movements on a larger scale (Hirzel et al, 2006;Wang et al, 2008;Richards-Zawacki, 2009;Wang and Summers, 2010). For selecting appropriate models, we constructed cost layers accounting for 63 estimated models based on combinations of the six environmental variables and compared the cost layers with those predicted by our genetic analysis (Supplementary Table S4).…”

“…We then used the inverse of these estimated values for LCP analysis (because lower suitability should have a higher cost) to assign cost to each cell on the cost layer (Hirzel et al, 2006;Wang et al, 2008;Richards-Zawacki, 2009;Wang and Summers, 2010). We conducted LCP analysis on these cost layers for each species by using the Spatial Analyst extension in ArcGIS.…”

“…In addition, even if some information is known, it can be difficult to incorporate observation information based on environmental and landscape factors onto the cost-matrix layer. One of the promising alternatives to predetermination is integration of ecological niche modeling (ENM) for cost assignment (Graham et al, 2004;Wang et al, 2008;Richards-Zawacki, 2009). …”

Isolation by distance and landscape connectivity are fundamental factors underlying speciation and evolution. To understand how landscapes affect gene flow and shape population structures, island species provide intrinsic study objects. We investigated the effects of landscapes on the population structure of the endangered frog species, Odorrana ishikawae and O. splendida, which each inhabit an island in southwest Japan. This was done by examining population structure, gene flow and demographic history of each species by analyzing 12 microsatellite loci and exploring causal environmental factors through ecological niche modeling (ENM) and the cost-distance approach. Our results revealed that the limited gene flow and multiple-population structure in O. splendida and the single-population structure in O. ishikawae were maintained after divergence of the species through ancient vicariance between islands. We found that genetic distance correlated with geographic distance between populations of both species. Our landscape genetic analysis revealed that the connectivity of suitable habitats influences gene flow and leads to the formation of specific population structures. In particular, different degrees of topographical complexity between islands are the major determining factor for shaping contrasting population structures of two species. In conclusion, our results illustrate the diversification mechanism of organisms through the interaction with space and environment. Our results also present an ENM approach for identifying the key factors affecting demographic history and population structures of target species, especially endangered species.

“…These models include habitat suitability index model (Singh et al, 2009;Wang et al, 2008), graph theoretic model (Jordan et al, 2003), network and corridor models (Nikolakaki, 2004) and weighted landscape graph model (Saura, 2010). These models can be a good simulation of landscape connectivity at the landscape scale.…”

A B S T R A C TUrbanization is accompanied by the intense transformation and conflicts among different land use types that produce a series of economic, social, and environmental impacts. Ascertaining the quantity and pattern optimization of urban ecological land is critical to solving urban environmental problems and realizing urban sustainable development. Using the Chinese city of Changzhou, an important and typical city in the Yangtze River delta, as the case study, we applied the minimum cumulative resistance model (MCRM) to calculate the amount of ecological land that meets the demand of socioeconomic development and ecological protection considerating the source of ecological land and constructed land, ecosystem services, and the resistance plane. Results showed that the suitable ecological land area is about 1006.9 km 2 , which is 53.8% of the total urban area of Changzhou, and is mainly distributed in Wujin and Xinbei districts. Considering the ecological land space and functional changes of the study area and comparing the current land use status with the model simulation results, we propose three land use types. For urban ecological land, positive protection measures and prohibiting economic development initiatives are necessary. For ecotones between urban developed land and ecological land, protection should be given priority and economic development activities should be rigidly controlled. For constructed land, measurements and policies should be taken to promote reasonable development and improve land intensity.

Green Infrastructure and Ecological Corridors: A Regional Study Concerning Sardinia

Abstract:We propose a methodological approach to identify a multifunctional green infrastructure (GI) on the basis of four values (conservation value, natural value, recreation value and anthropic heritage) that represent many functions (biodiversity conservation, supply of ecosystem services, recreation, identity building) performed by the landscape. By taking the Italian region of Sardinia as a case study, we argue that the methodology can support the making of landscape plans as understood in the European Landscape Convention. Moreover, we propose and implement a methodology to identify ecological corridors (ECs) connecting Natura 2000 sites (N2Ss), based on the prioritization of functional land patches related to their suitability to ecosystem services delivery, paying particular attention to biodiversity maintenance and enhancement, and taking Sardinia as spatial regional context. The methodology consists of two steps: (i) identifying the most suitable patches to be included in ECs on the basis of their connectivity, that is, on their negative attitude towards contributing to landscape fragmentation; (ii) assessing, through a discrete-choice-model, the suitability of these ECs to be included in a regional GI, starting from the territorial taxonomy based on biodiversity characteristics related to N2Ss, habitat suitability, and recreational and landscape potentials.
