“…Studies of larger cities clearly demonstrate that in areas outside the city centre urbanization has a negative impact on the richness and biodiversity of small mammal species and even green areas located on the outskirts of a city (where urban species richness and diversity were relatively high) differed significantly from rural areas (Cavia et al 2009;Łopucki et al 2013;Gortat et al 2014). Such observations are consistent with the predictive curves presented in the review by McDonnell and Hahs (2008) showing a Bnegative response^of urban biodiversity along the urban-rural gradient.…”

“…Andrzejewski et al 1978;Frynta et al 1994;Cavia et al 2009;Gortat et al 2014). These effects are expressed as a reduction in species richness and diversity, a radical decline in abundance of urban sensitive species and an increase in the proportion of synurbic species.…”

“…In the case of urban fauna, the main effects of urbanization are: biotic homogenization -a decrease in richness and diversity of fauna species along with the degree of urbanization (e.g. McKinney 2008;Cavia et al 2009;Faeth et al 2011); adaptation of some species (known as synurbic) to specific urban conditions (Luniak 2004;Francis and Chadwick 2012); changes in biocenotic relationships -lower pressure from predators and competitors (e.g. Lepczyk et al 2003;Major et al 1996), extension of breeding seasons, increase of abundance, and a decreased in territory in species that are urban adapted (Gliwicz et al 1994) There is also reduced fear of humans and tolerance to urban noise (Ditchkoff et al 2006;Møller 2009).…”

“…From studies of large cities (Sorace 2001;Elvers and Elvers 1984;Gortat et al 2014;Frynta et al 1994;Cavia et al 2009;Garden et al 2007Garden et al , 2010Baker et al 2003), we know that most native species of small mammals become extinct or decrease in number (urbanization-sensitive species), and only a few species are able to adapt to urban conditions (synurbic species). The main factors determining the occurrence of small mammals in large cities are also known: small mammals prefer habitats with dense undergrowth or ground cover and with low levels of spatial isolation (Babińska-Werka et al 1979;Cavia et al 2009;Gomes et al 2011;Łopucki et al 2013). We expected that in small cities, where even downtown green areas are relatively close to the outskirts and green corridors allow movement of small ground-dwelling mammals to and from the city, the small mammals community would be only minimally affected.…”

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.

Urbanization processes are taking place at a very high rate, especially in Africa. At the same time, a number of small mammal species, be they native or invasive, take advantage of human‐induced habitat modifications. They represent commensal communities of organisms that cause a number of inconveniences to humans, including potential reservoirs of zoonotic diseases. We studied via live trapping and habitat characterization such commensal small mammal communities in small villages to large cities of Senegal, to try to understand how the species share this particular space. Seven major species were recorded, with exotic invasive house mice (Mus musculus) and black rats (Rattus rattus) dominating in numbers. The shrew Crocidura olivieri appeared as the main and more widespread native species, while native rodent species (Mastomys natalensis, M. erythroleucus, Arvicanthis niloticus and Praomys daltoni) were less abundant and/or more localized. Habitat preferences, compared between species in terms of room types and characteristics, showed differences among house mice, black rats and M. natalensis especially. Niche (habitat component) breadth and overlap were measured. Among invasive species, the house mouse showed a larger niche breadth than the black rat, and overall, all species displayed high overlap values. Co‐occurrence patterns were studied at the global and local scales. The latter show cases of aggregation (between the black rat and native species, for instance) and of segregation (as between the house mouse and the black rat in Tambacounda, or between the black rat and M. natalensis in Kédougou). While updating information on commensal small mammal distribution in Senegal, a country submitted to a dynamic process of invasion by the black rat and the house mouse, we bring original information on how species occupy and share the commensal space, and make predictions on the evolution of these communities in a period of ever‐accelerating global changes.

The distribution of mammalian pests is altered by changes in global climate and land cover. Rattus norvegicus is a significant pest that contributes to the catastrophic decline of native species. Therefore, the studies identifying potentially suitable habitats for Rattus norvegicus and the impact of future climate change on the extent of such habitats are crucial. In this study, we determined the effects of key environmental and ecological variables on Rattus norvegicus in South Korea by considering multiple climate changes, land cover, and dispersal scenarios. The available presence locations with the least correlated variables and Maximum Entropy (MaxEnt) model along with multiple Shared Socioeconomic Pathways (SSPs) scenarios were utilized to project current and future habitat suitability. Additionally, three dispersal scenarios were incorporated into the model to enrich the analysis of potential future distribution. Mean diurnal temperature, elevation, and nighttime light were the three most important variables contributing to the species' distribution. The coastal and northern regions of South Korea constitute currently suitable habitats and are expected to exhibit a significant increase in the species' population under future climate projections. The results demonstrate the potential expansion of Rattus norvegicus as a result of changes in climate and land cover and provide crucial insights into the species' environmental niches. This study highlights the potential areas for monitoring, early warning, and developing effective prevention and control strategies for Rattus norvegicus.
