“…Similar results have been found for other ground dwelling arthropods (Vergnes et al. ), indicating that the urban environment may select for species with greater dispersal ability. Dispersal traits ultimately determine the ability of a species to arrive within a habitat and therefore deserve more attention to understand community assembly rules in urban landscapes.…”

Abstract. The majority of humanity now lives in cities or towns, with this proportion expected to continue increasing for the foreseeable future. As novel ecosystems, urban areas offer an ideal opportunity to examine multi-scalar processes involved in community assembly as well as the role of human activities in modulating environmental drivers of biodiversity. Although ecologists have made great strides in recent decades at documenting ecological relationships in urban areas, much remains unknown, and we still need to identify the major ecological factors, aside from habitat loss, behind the persistence or extinction of species and guilds of species in cities. Given this paucity of knowledge, there is an immediate need to facilitate collaborative, interdisciplinary research on the patterns and drivers of biodiversity in cities at multiple spatial scales. In this review, we introduce a new conceptual framework for understanding the filtering processes that mold diversity of urban floras and faunas. We hypothesize that the following hierarchical series of filters influence species distributions in cities: (1) regional climatic and biogeographical factors; (2) human facilitation; (3) urban form and development history; (4) socioeconomic and cultural factors; and (5) species interactions. In addition to these filters, life history and functional traits of species are important in determining community assembly and act at multiple spatial scales. Using these filters as a conceptual framework can help frame future research needed to elucidate processes of community assembly in urban areas. Understanding how humans influence community structure and processes will aid in the management, design, and planning of our cities to best support biodiversity.

“…Indeed, previous studies have reported a drastic decline in population size of wildlife species under landsharing development for multiple taxa (Gagné & Fahrig, 2010a,b;Sushinsky et al, 2013;Soga et al, 2014). This is unsurprising in as much as, whilst some components of biodiversity do well in close proximity to human activities (Evans, Chamberlain, Hatchwell, Gregory, & Gaston, 2011), others do not (McKinney, 2006;Soga & Koike, 2012;Vergnes, Pellissier, Lemperiere, Rollard, & Clergeau, 2014). These facts suggest the existence of an unfortunate dilemma in the design of cities between forms that most effectively enhance the protection of regional biodiversity and those that provide for experiences of nature.…”

“…The effects of urbanisation on biotic communities have commonly been studied across urban-rural gradients (McDonnell and Pickett 1990;McDonnell and Hahs 2008;McKinney 2008;Niemelä and Kotze 2009;Cavia et al 2009;Vergnes et al 2014). This approach has the advantages of being intuitive and easily measured.…”

Fundamental principles regarding urban biodiversity are based on studies conducted in large cities. However we cannot know whether the same phenomena occur in smaller cities or how small cities affect biodiversity. Small cities are an inherent element of urbanization and in the future, most global urban growth is expected to take place in small and mediumsized cities. Understanding the effects of small cities on biodiversity will be an important aspect in planning urban land expansion. Our study examined the effects of a small city on communities of small ground-dwelling mammals on 41 sites arranged in a four step gradient of urbanization. In 6700 trapdays, we caught 2333 individuals comprising 15 species. In the downtown area the same phenomena as those described for large cities were observed: a reduction in species richness and diversity, a decline in the abundance of urban sensitive species and an increase in synurbic species. However, in contrast to large city studies, green areas outside the downtown area did not differ from rural sites in small mammal population parameters. This phenomenon of relatively unchanged fauna outside the downtown area shows that small cities have the potential to maintain a high level of diversity of small grounddwelling mammals if appropriate planning of further building expansion is implemented. More studies of small cities are needed to better assess their impact on biodiversity. This knowledge can then be applied in better planning for urban wildlife. Generalizations based solely on large city studies are inadequate and may lead to incomplete or inappropriate conservation strategies for small cities.
