“…These observations should be expected, as common and rare species are known to react differently to anthropogenic disturbance. In particular, common species, many of which are generalists, are often able to take advantage of habitats altered by human activities, whereas rare or specialist species usually become rarer (McKinney and Lockwood 1999; Davies et al 2004;Fairbanks 2004). Alien bird species that are successful at establishing a population and spreading are often pre-adapted for invasion by being opportunistic generalists that are closely associated with humans and tolerant of a wide range of environmental conditions (Dean 2000;Duncan et al 2003).…”

The spatial distribution of alien species richness often correlates positively with native species richness, and reflects the role of human density and activity, and primary productivity and habitat heterogeneity, in facilitating the establishment and spread of alien species. Here, we investigate the relationship between the spatial distribution of alien bird species, human density, and anthropogenic and natural environmental conditions. Next, we examined the relationship between the spatial distribution of alien bird species and native bird species richness. We examined alien species richness as a response variable, using correlative analyses that take spatial autocorrelation into account. Further, each alien bird species was examined as a response variable, using logistic regression procedures based on binary presence-absence data. A combination of human density and natural habitat heterogeneity best explained the spatial distribution of alien species richness. This contrasts with the results for individual alien species and with previous studies on other non-native taxa showing the importance of primary productivity and anthropogenic habitat modification as explanatory variables. In general, native species richness is an important correlate of the spatial distribution of alien species richness and individual alien species, with alien species being more similar to common species than to rare species.

“…Landscape diversity indices were found to correlate positively with species richness whereas landscape fragmentation indices affected the group of the threatened species (Honnay et al 2003). Percentage cover of certain land use types might serve as useful indicators for species richness at the landscape scale (Dauber et al 2003;Fairbanks 2004). Through the calculation of BD, this paper attempted to quantify the regional biodiversity at the landscape level on the basis of the landscape pattern indicators.…”

Resolving the conflicts between biodiversity conservation and socioeconomic development is a global pursuit for the long-run prospects of the human species. Based on Wenchuan County, a typical county in southwestern China, a group of 20 indicators quantifying regional biodiversity and socioeconomic development was established to classify and evaluate the county area spatially. A fuzzy c-means clustering (FCM) algorithm was used as the classification method. Three indices including BD, DL and DR characterizing the value of biodiversity, the level and rate of socioeconomic development of the delineated regions were formulated. The results indicated that Wenchuan County was optimally classified into 4 types of regions (region I to IV). The area percentages of the regions vary widely from 4.3 to 65.7%. The sequences of the regions on biodiversity, socioeconomic development level, and socioeconomic development rate were, respectively, IV>II>III>I, I>III>II>IV and III>I>II>IV. The spatial strategy on coordinating biodiversity conservation and regional development is to develop mainly from the east(I, II, III) and to conserve mainly in the west(IV). Eco-industry, such as eco-tourism and eco-agriculture, need to be emphasized in the process of regional development. The quantitative methods used here may have a wide applicability.

“…High connectivity of habitats also favors larger local populations through immigration (Renjifo, 2001). Variations in bird abundances and biodiversity among landscapes may be associated with variations in floristic composition and structure (Renjifo, 2001;Herrando and Brotons, 2002;Fairbanks, 2004;Mitchell et al, 2006;Ernoult et al, 2006). In this study, landscape metrics were applied to analyze the landscape patterns under the five scenarios of protected bird diversity.…”
