“…Increasing urbanization raises many concerns about sustainability of biodiversity in terrestrial (Laurie 1979, Breuste et al 1998, McIntyre 2000 and marine (Suchanek 1994, Smith et al 2000 habitats. Despite many definitions of biodiversity (May 1994), it is often estimated as numbers and types of species in an area, usually by sampling, or from compiled lists of species.…”

On artificial surfaces (seawalls) in Sydney Harbour (Australia), local biodiversity of grazers differs between sandstone and concrete constructions because limpets Siphonaria denticulata are more abundant on sandstone, while Patelloida latistrigata are more abundant on concrete walls. Competition between siphonarian and patellid limpets is unstudied on artificial structures, although the limpets are common and are known to compete in natural habitats. We tested hypotheses that the substratum (concrete or sandstone), intra-and/or interspecific competition, or a combination of factors, influence recruitment, survival, rates of grazing, or the quantity and types of algal food to explain the observed patterns. Such analyses enable better understanding of the processes influencing diversity. Both species recruited more to concrete than to sandstone plates. S. denticulata recruited more in the presence of conspecifics and slightly less in the presence of P. latistrigata. Results varied between locations and experiments, but each species survived better on concrete, which had more macro-and micro-algal food. Increased densities of P. latistrigata reduced survival of conspecifics and of S. denticulata. S. denticulata had no effect on survival of P. latistrigata, but reduced amounts of macro-algae. P. latistrigata did not affect macro-algae. Initially, there were more micro-algae on concrete and a minor effect of large densities of S. denticulata. After 95 d, differences between habitats decreased and P. latistrigata were more strongly associated with reduced amounts of micro-algae. Neither substratum, density, nor mix of limpets affected rates of grazing. Thus, interspecific interactions were similar to predictions from knowledge of natural habitats, despite the different characteristics of artificial habitats and the reduced intertidal area available for grazing. Recruitment and competition were important in explaining different densities of these limpets on sandstone and concrete walls. Increasing urbanization requires more experimental tests to identify how well current theories of intertidal ecology and of the processes maintaining local biodiversity can apply to artificial shorelines.

“…Urbanization is a serious threat to biodiversity and is a leading cause of declines in animal populations (Czech et al 2000, McIntyre 2000, McKinney 2002. Urban development results in the conversion of natural space to buildings and pavement, resulting in loss of habitat and fragmentation of habitats suitable for wildlife, changes in local climate change and hydrology, and pollution (McIntyre et al 2001).…”

“…For example, across gradients of urban development, arthropod species richness may directly correlate with plant diversity, richness, and density (Raupp et al 2009). Some urban areas have very high spatial habitat heterogeneity at small spatial scales due to land use and implementation of gardens (McIntyre et al 2000, McKinney 2008, Savard et al 2000. Urban gardens can have higher primary productivity than surrounding areas due to irrigation, fertilizers, and other factors, leading to increases in arthropod populations, species richness, and biodiversity (McIntyre 2000, McKinney 2008.…”

“…They reproduce relatively quickly and usually have high rates of fecundity, meaning they may respond rapidly to small-scale changes such as differences in soil or vegetation. They are abundant, allowing for large sample size, and are relatively easy to sample in comparison to larger organisms (McIntyre 2000, McIntyre et al 2001. Arthropod predators also provide a variety of ecosystem services in agricultural landscapes such as pest control and nutrient cycling (McIntyre et al 2001, Isaacs et al 2009).…”

ABSTRACT. Four species of scorpions (Ananteris mauryi Lourenço, 1982, Tityus neglectus Mello-Leitão, 1932, T. pusillus Pocock, 1893 and T. stigmurus (Thorell, 1876) were collected in the "Mata do Buraquinho", João Pessoa, state of Paraíba, Brazil. Aspects of biology for A. mauryi and new records on the geographic distribution of other species were annotated. Notes on the abundance and sex ratio on A. mauryi, the most abundant species in the area, are presented and discussed.
