“…The presence of vegetation is a key factor driving the presence of amphibians in urban ponds, although not for all species. This was shown in ponds from several cities, including Shanghai (China; Zhang et al 2016), Melbourne (Hamer et al 2012) and Canberra (Westgate et al 2015; Australia), Portland (Oregon, USA; Holzer 2014), and Edmonton (Canada; Scheffers and Paszkowski 2013).

Review: Toward management of urban ponds for freshwater biodiversity

Many cities around the world are expanding and this trend in urbanization is expected to sharply increase over coming decades. At the same time, the integration of green and blue spaces is widely promoted in urban development, potentially offering numerous benefits for biodiversity. This is particularly relevant for urban waterbodies, a type of ecosystem present in most cities. However, site managers often lack the knowledge base to promote biodiversity in these waterbodies, which are generally created to provide other ecosystem services. To address this, our review presents guidelines for promoting biodiversity in urban ponds. We found a total of 516 publications indexed in ISI Web of Sciences related to this topic, of which 279 were retained for the purposes of our review. The biodiversity of urban ponds, measured by species richness, appears to be generally lower than in rural ponds; however, urban ponds often support threatened species. Furthermore, if well managed, urban ponds have the potential to support a much greater biodiversity than they currently do. Indeed, this review shows that a range of urban factors can impair or promote pond biodiversity, including many that can easily be controlled by site managers. Local factors include design (surface area, pond depth, banks and margins, shade, shoreline irregularity), water quality (conductivity, nutrients, heavy metals), and hydroperiod and biotic characteristics (stands of vegetation, fish, invasive species). Important regional factors include several indicators of urbanization (roads, buildings, density of population, impervious surfaces, car traffic), and the presence of other wetlands or green spaces in the surrounding landscape. We considered each of these factors and their potential impact on freshwater biodiversity. Taking into account the management measures listed in the publications reviewed, we have proposed a framework for the management of urban ponds, with guidelines to promote biodiversity and other ecosystem services, and to avoid ecosystem disservices or the creation of ecological traps. At the city scale, the biodiversity of a pondscape benefits from a high diversity of pond types, differing in their environmental characteristics and management.

“…At least 11 anuran species were recorded living in the city until the 1980s (Huang et al., 1980), decreasing to eight by 2001 (SFB, 2004), and only five in 2015 (The Second National Terrestrial Vertebrates Survey, Shanghai, unpublished). Among the five anuran species, the eastern golden frog ( Pelophylax plancyi ) is most abundant and widely distributed across the city (Huang et al., 2018; Li et al., 2018; Zhang et al., 2016). As a typical pond‐breeder (Fei et al., 2010), P. plancyi may be the most sedentary anuran species in Shanghai, being observed mainly in or around water bodies (e.g., ponds, small rivers, and drainage ditches; Li et al., 2017; Yue, 2019).…”

Understanding the mechanisms of how urbanization influences the evolution of native species is vital for urban wildlife ecology and conservation in the Anthropocene. With thousands of years of agriculture‐dominated historical urbanization followed by 40 years of intensive and rapid urbanization, Shanghai provides an ideal environment to study how the two‐stage urbanization process influences the evolution of indigenous wildlife, especially of anuran species. Therefore, in this study, we used mitochondrial Cyt‐b gene, microsatellite (SSR), and single nucleotide polymorphism (SNP) data to evaluate the demographic history and genetic structure of the eastern golden frog (Pelophylax plancyi), by sampling 407 individuals from 15 local populations across Shanghai, China. All local populations experienced bottlenecks during historical urbanization, while the local populations in urban areas maintained comparable contemporary effective population sizes (Ne) and genetic diversity with suburban and rural populations. Nevertheless, the rapid modern urbanization has already imposed significant negative effects to the integrity of populations. The 15 local populations were differentiated into eight genetic clusters, showing a spatial distribution pattern consistent with the current urbanization gradient and island–mainland geography. Although moderate gene flow still occurred from the rural peripheral cluster to urban and suburban clusters, population fragmentation was more serious in the urban and suburban populations, where higher urbanization levels within 2‐km radius areas showed significant negative relationships to the Ne and genetic diversity of local populations. Therefore, to protect urban wildlife with limited dispersal ability, improving conditions in fragmented habitat remnants might be most essential for local populations living in more urbanized areas. Meanwhile, we highlight the need to preserve large unfragmented rural habitats and to construct corridor networks to connect discrete urban habitat remnants for the long‐term wildlife conservation in intensively urbanizing environments.

“…Currently, more than 50% of the world's human population lives in urban areas and it is estimated that this number will increase to approximately 65% by 2030 (Grimm et al 2008, United Nations 2018. Urbanization can drastically alter the chemical, physical, and ecological condition of ecosystems, with several studies highlighting the negative effects of urbanization on species dispersal (Findlay et al 2001, Rubbo andKiesecker 2005), ecological interactions (Fischer et al 2012), and community structure (Christie et al 2010, Zhang et al 2016, Gagné and Fahrig 2007, McDonnell et al 1997, Kinzig and Grove 2001, Johnson et al 2013. For example, in an investigation of bird communities along a gradient of urban influence, Dale (2018) found that urbanization led to a predominance of species with generalist diets and nesting habits.…”

“…Amphibians are the most threatened group of vertebrates globally, with approximately 40% of its species classified in at least one threat category of the IUCN (IUCN 2020). Nearly 1,000 amphibian species are classified as threatened with extinction because of land use changes for urban development (Maxwell et al 2016), likely due to the fact that most amphibian species exhibit complex life cycles (Wells 2007), and urbanization can seriously affect both aquatic and terrestrial environments (Zhang et al 2016). For example, Knutson et al (1999) showed that urban development affected both tadpole and adult stages, by modifying terrestrial environments as well contaminating water bodies.…”

The rapid expansion of urban areas in which natural and semi-natural areas are replaced by human infrastructure, such as buildings and streets, is a major threat to biodiversity worldwide. However, little is known about how the structure of biotic communities is affected by urbanization in the tropics. Here, we tested the effect of land use types in urban and peri-urban areas on frog species richness and community composition in central Brazil. We selected 20 ponds differing in size and surrounding levels of urbanization as well as natural forest cover. We then used a Poisson GLM and a distance-based Redundancy Analysis (db-RDA) to relate species richness and community composition, respectively, to environmental variables. Variation in species richness was best explained by pond size (positive effect) and amount of urbanization (negative effect) in the surrounding 500 m. Community composition was mainly driven by species turnover than by nestedness, with db-RDA showing that turnover was explained primarily by urban infrastructure and forest cover. Our results indicate that urbanization negatively influences species richness. Moreover, as the amount of urbanization increased, several species were replaced by others taxa that appear better adapted to urban environments. Our results indicate that maintaining large ponds with surrounding native vegetation in urban environments might be an effective strategy for conserving frog communities.
