“…Las especies nativas de roedores registradas en los espacios verdes no urbanos son, en su mayoría, especies que toleran disturbios humanos y que generalmente son capturadas en zonas de transición (ecotonos) y en bosques perturbados, cultivos y áreas abiertas, como Peromyscus mexicanus, Sigmodon hispidus y Reithrodontomys mexicanus (Horváth et al 2001;Cruz et al 2010). Sin embargo, el roedor más abundante en los espacios verdes no urbanos fue P. levipes, especie que fue capturada en el interior del bosque en el sitio denominado El Encuentro.…”

Introduction:The demands of space for housing, industrial, commercial, and recreation space, are increasing as the human population continues to focus on urban areas. This implies an increase and constant degradation of natural environments. Despite the negative effect that the urban areas have on the biodiversity, these can be considered as important areas for the conservation of native flora and fauna. This is because urban areas have different types of land uses, where green spaces, represent an important component for the conservation of biological diversity. This study estimated the richness and abundance of rodents and bats in urban and non-urban green spaces in the city of San Cristobal de Las Casas (SCLC), Chiapas, Mexico. Given the great variety of types of green space in an urban area, the richness and abundance of rodents and bats in these areas will depend on the characteristics of the vegetation (richness and abundance of vegetal species) and the formation of the surrounding matrix (types of uses of soil around the green space). Methods:This study was conducted in 10 sites with presence of green spaces in the urban area and the periphery of SCLC. The rodents and bats were captured monthly from March to August 2013, for three consecutive nights per site. We compared the richness of species, relative abundance and diversity index between urban and non-urban green spaces.Results: There were a total of 12 species and 108 individuals, belonging to three families, Muridae, Phyllostomidae, and Vespertilionidae. In the non-urban green spaces were captured 55 individuals of four species of native rodents, and 19 individuals of three species of bats. In the urban green spaces were captured 11 individuals of three species of rodents (a species was native), and 23 individuals of four species of bats. For the richness of species of mammals, the correlation analysis showed very low values of relationship regarding to the independent variables. Discussion and conclusions:The number of species recorded in this study in the two groups of green spaces (urban and non-urban), show that these spaces can hold more than 40% of the total number of species recorded for the municipality of San Cristóbal de Las Casas. The capture of larger number of individuals of species of native rodents in the non-urban green spaces may be that in these areas there is greater availability of resources such as food, shelter and breeding sites, since these sites are part of a remnant of forest. In the case of bats, there were not significant differences in their diversity between urban and non-urban green spaces. This study found that the urban and non-urban green spaces in the interior and periphery of the city of SCLC, are important for the native fauna of rodents and bats. In this way, preserving green areas on the periphery of an urban landscape is decisive for the conservation of the native fauna of the region, since they are reservoirs of their diversity.

“…Una manera de medir la alteración por el uso de los sistemas naturales, es comparando la composición y abundancia de las comunidades de roedores en sitios con vegetación madura, en recuperación y en sistemas productivos (August 1983;Mellink 1985;Horváth et al 2001;Riojas-López, 2006). Se ha documentado que los sitios perturbados determinan la abundancia y diversidad de pequeños roedores debido a que son complejos y heterogéneos en espacio y tiempo (Horváth et al 2001; Vera y Conde y Rocha 2006).…”

The aim of this study was to compare the diversity of small rodents along four unequally disturbed habitats in a low deciduous forest in Dzilam de Bravo, Yucatan: an abandoned pastureland (AP) with five-year old (SCA), ten-year old (SDA), and more than ten-year old (SMD) forests. A total of 478 rodents were captured with 1,754 recaptures from May 2005 to April 2006. They were included in six species and two families. Our work was done in two grids of 5,000 m 2 with a distance of 10 m between rows and columns; Sherman's traps were set two nights per month in all sites. The habitat with the highest diversity (H'= 1.328) and specific richness was the site with the highest disturbance and the lowest diversity (H'= 0.6321) (PA), but the highest abundance was in the SMD forest. Differences in diversity among sites were significant (P < 0.05), except between SCA and SDA forests. The abundance values differed strongly in all sites. The abundance patterns of O. phyllotis were influenced by a disturbance gradient due to human influence and topography of the area, factors associated to the diversity observed.Key words: Diversity, abundance, disturbance gradient, small rodents, low deciduous forest, Yucatan, Mexico.De mayo de 2005 a abril de 2006 se monitorearon pequeños roedores en cuatro sitios que representaron un gradiente de perturbación en Dzilam de Bravo y localidades aledañas: Pastizal abandonado (PA), selva baja caducifolia de cinco años (SCA), selva de hasta diez años (SDA) y selva de más de diez años de edad (SMD). El objetivo fue comparar la diversidad de ratones a través de este gradiente. Se implementaron dos cuadrantes de 5,000 m 2 /sitio, usando 50 trampas Sherman en una cuadrícula equidistante de 10 m durante dos noches consecutivas por mes en cada sitio. Se capturaron 478 ratones de seis especies con 1,754 recapturas. La SMD aportó el 38% de las capturas mientras que PA el 16%. Ototylomys phyllotis y Peromyscus yucatanicus aportaron el 47% y el

“…The ability of small mammals to use the microhabitat in and around areas experiencing plant invasion, and to use the invasive plants themselves, affects the likelihood of persistence for both the small mammals and native plants in urban ecosystems Small mammal species that persist within urban parks and green spaces are primarily generalists (Mahan and O'Connell 2005;Cavia et al 2009). While ideal habitat for small mammals has high structural complexity, (Horvath et al 2001), abundant woody debris (Fauteux et al 2012;Kellner and Swihart 2014), and canopy cover (Zollner and Crane 2003), generalist species can work within their broad habitat preferences to best take advantage of available habitat components (Bellows et al 2001). Flexibility in habitat requirements allows them to persist in often heavily disturbed, highly invaded urban parks.…”

Persons, William, "Impact of urban factors and invasive species on white-footed mouse (Peromyscus leucopus) habitat use and foraging behavior in an urban forest park." (2015). Urban ecosystems demonstrate high levels of anthropogenic land-use change, modification of abiotic inputs, and altered disturbance regimes; these changes directly alter habitats. These changes result in reduced native biodiversity, creating available niches often filled by invasive species. Urban parks often serve as reserves for native species less suited to survival in urban areas, helping to preserve native biodiversity through mitigation of anthropogenic effects. Understanding what changes affect these urban parks, how the vegetative community responds, and how species (small mammals in particular) modify their behaviors to persist in these areas will increase our ability to manage urban areas for maximum biodiversity.This research project took place in Twin Parks, a forested bottomland urban park.The vegetative community, habitat structure, human presence, and the small mammal community were assessed at multiple scales. Giving-Up Density was also assessed.Chapter 1 assesses the habitat at a macro scale, determining what elements of the vegetative community, vertical structure, and environment contribute to patterns of white-footed mouse (Peromyscus leucopus) capture. Chapter 2 assesses habitat selection viii at a microhabitat scale, examining how P. leucopus uses the specific invasive Amur honeysuckle (Lonicera maackii). Chapter 3 examines P. leucopus anti-predator responses in relation to coarse woody debris (CWD) and honeysuckle canopy cover using GivingUp-Density trials.White-footed mice select for areas of greater canopy cover at the macro scale.White-footed mice selected for areas with more CWD at the micro-scale, while also potentially avoiding higher invasive species richness. White-footed mice preferentially foraged under the honeysuckle canopy in response to changes in temperature and humidity. This study suggests that the interaction between P. leucopus and ground layer invasive species is complex, and that the effect of moonlight may be diminished in this urban park.ix
