“…The inXuence of disturbance on mammal and Xea characteristics was most evident in analyses restricted to the forest biome (Table 2), probably reXecting greater statistical power as sample size increased. Like Wilcox and Gubler (2005) and Tikhonova et al (2006), we found that richness and diversity (Shannon's H; data not shown but trends and signiWcance tests mirrored those produced with …”

“…such as murine typhus and Rocky Mountain fever (Gage et al 1995). Human-induced habitat change can aVect small mammals (Tikhonova et al 2006) and Xeaborne mammal diseases (Azad et al 1997) but does not always lead to increased disease incidence (Collinge et al 2005). The presence and abundance of Xeas are directly linked to the likelihood and spread of Xea-borne disease like plague and are closely tied to the presence and abundance of their hosts (Lorange 2005;Eisen et al 2006;Krasnov et al 2006a).…”

“…Thus, the overall eVect of disturbance on disease spread is a culmination of individual eVects on host-parasite interactions, habitat dependencies of host and Xea species, and host speciWcity of Xeas. For instance, anthropogenic disturbance decreases mammal community diversity (Tikhonova et al 2006), and should lead to decreased Xea diversity. However, diversity loss may favor common host species, which tend to harbor more Xea species (Egoscue 1976) and lead to an increase in overall Xea abundance.…”

Anthropogenic disturbance may lead to the spread of vector-borne diseases through effects on pathogens, vectors, and hosts. Identifying the type and extent of vector response to habitat change will enable better and more accurate management strategies for anthropogenic disease spread. We compiled and analyzed data from published empirical studies to test for patterns among flea and small mammal diversity, abundance, several measures of flea infestation, and host specificity in 70 small mammal communities of five biomes and three levels of human disturbance: remote/wild areas, agricultural areas, and urban areas. Ten of 12 mammal and flea characteristics showed a significant effect of disturbance category (six), biome (four), or both (two). Six variables had a significant interaction effect. For mammal-flea communities in forest habitats (39 of the 70 communities), disturbance affected all 12 characteristics. Overall, flea and mammal richness were higher in remote versus urban sites. Most measures of flea infestation, including percent of infested mammals and fleas/mammal and fleas/mammal species increased with increasing disturbance or peaked at intermediate levels of disturbance. In addition, host use increased, and the number of specialist fleas decreased, as human disturbance increased. Of the three most common biomes (forest, grassland/savanna, desert), deserts were most sensitive to disturbance. Finally, sites of intermediate disturbance were most diverse and exhibited characteristics associated with increased disease spread. Anthropogenic disturbance was associated with conditions conducive to increased transmission of flea-borne diseases.

Amphibians and reptiles have already been investigated as for their patterns of species occurrence and abundance in agricultural areas (Beja & Alcazar, 2003;Fabricius, Burger & Hockey, 2003;Porej, Micacchion & Hetherington, 2004;Denoe¨l & Ficetola, 2007;Piha et al, 2007;Schutz & Driscoll, 2008), whereas such studies are almost neglected in urban habitats (Gagn´e & Fahrig, 2007).…”

Urban areas are primary causes of species' range fragmentation and reduction. However, relatively few studies have attempted to describe the habitat variables influencing the diversity and conservation of amphibians and reptiles, particularly in Mediterranean Europe and in large metropolitan areas. We explored this broad conservation ecology problem by studying the richness and diversity patterns in relation to a suite of six independent habitat variables in Rome, one of the most ancient cities of the world. We considered all the green remnant areas (n = 62) of Rome, ranging 1 to 41000 ha in size, which are interspersed within a sea of urbanized matrix. A total of 10 amphibian and 15 reptile species were studied. Their presence/absence patterns were assessed and the effects of the various habitat variables on each species were predicted by a logistic regression model. A total of 1261 presence records (404 amphibians and 857 reptiles) were analysed. Fragment size and wood size within each fragment did correlate significantly with the species richness of both amphibians and reptiles, and there was a clear threshold effect after 50 ha of wooded surface. The presence of water bodies positively affected the species distribution. One amphibian and three reptiles inhabited exclusively fragments 450 ha. The distance from the centre did not affect fragment species richness. The presence of most species of both amphibians and reptiles was positively influenced by the irregular versus circular shape of the wooded area. The legal protection of a given area did not influence the observed patterns but the total number of sheltered species. Overall, our study suggests that, in order to maintain the current diversity and population viability, it is necessary, in addition to water bodies' maintenance, to (1) preserve the wooded landscapes over 50 ha; (2) promote irregularly shaped increases in the wood surface; (3) maintain ecotonal boundaries.

There are, however, many more examples of such a negative influence on species richness of increasing urbanization at local scales, a pattern that has been widely reported since the 1960s, when urban ecology started to become of pressing relevance due to escalating urban sprawl (e.g.…”

Scale dependence of the correlation between human population presence and vertebrate and plant species richness

2006

Human presence is generally negatively related to species richness locally, but the relationship is positive at coarse scales. An increase in the strength of the latter correlation with increasing study resolution has been documented within studies, but it is not known whether such a scale dependence is present across different studies. We test this with data on the spatial co-occurrence of human beings and the species richness of plants and vertebrates from a continuum of scales. The correlation coefficient between human presence and species richness is positively related to study grain and extent. The correlation turns from positive to negative below a study grain of c. 1 km and below a study extent of c. 10,000 km(2). The broad-scale positive correlation between human presence and species richness suggests that people have preferentially settled and generally flourished in areas of high biodiversity and/or have contributed to it with species introductions and habitat diversification. The scale dependency of the correlation between people and biodiversity's presence emphasizes the importance of the preservation of green areas in densely populated regions.
