“…Previous studies in Europe have shown that common species, such as house sparrows (Passer domesticus) and common starlings (Sturnus vulgaris), preferentially settle in urban sites with parks and gardens (Chamberlain et al 2007;Morelli et al 2018;Murgui 2009). Urban birds can find most of their food resources, which consist mostly of seeds and insects, in understory vegetation areas (Carvajal-Castro et al 2019;Huang et al 2015;Müller et al 2018). Moreover, understory vegetation areas can provide material for nest building, such as grass, straw, and twigs (Anderson 2006;Mainwaring and Healy 2019).…”

In the context of increasing urbanization, preserving urban biodiversity has become a priority because biodiversity appears to be a key element when evaluating the well-being of urban residents. Recently, urban management has relied on a 'renaturing' strategy to improve biodiversity, but the benefits of these policies remain debated. In this study, we evaluated the effects of urban land use and green corridors on (1) urban avian biodiversity, and (2) the presence of the most common (top 70%) and least common (bottom 30%) bird species. We surveyed bird diversity at 102 sites during the Spring in a small French city, and performed a PCA on several habitat structures (e.g. roads, houses, grassy areas) to determine the level of urbanization of each site. Then, we tested with GLMMs the effects of land use (PC1), distance to the edge of the city, and distance to the corridor on bird diversity. We found a positive effect of green infrastructures on bird species richness, and this effect was reinforced by the proximity to the green corridor. Thus, bird species richness and the presence of common species were positively impacted by the presence of green areas, the proximity to the city edge and the proximity to the green corridor. The presence of the green corridor contributed significantly to the presence of rare species, which emphasizes its role in promoting avian biodiversity. Green corridors are a key element of the urban landscape because they allow less common species to colonize cities, and thus enhance urban biodiversity.

“…Green spaces are a key element for biodiversity conservation in cities since they represent available habitat for a wide range of organisms (Cornelis and Hermy, 2004;MacGregor-Fors et al, 2016) and much of the research on diversity in urban green spaces has focused on birds (Magle et al, 2012;Beninde et al, 2015). Studies have mainly reported reductions in both the number of species and diversity indices together with compositional changes (Carvajal-Castro et al, 2019;Di Pietro et al, 2020 but see Benitez et al, 2021). Although species richness has been a widely-used measure of biodiversity to assess the effect of urbanization on bird communities (Rush et al, 2014;Canedoli et al, 2017;Matthies et al, 2017) the assumption of species being equivalent may not be ecologically precise (Chave, 2004).…”

Taxonomic, Phylogenetic and Functional Diversity of Bird Assemblages in Urban Green Spaces: Null Model Analyses, Temporal Variation and Ecological Drivers

Urban expansion is a pervasive driver of biodiversity loss. To understand the effects of urbanization on diversity, we investigated the response of bird taxonomic, phylogenetic, and functional diversity to urban green spaces’ characteristics in thirty-one green spaces of Mexico City. Selected sites encompassed variation of environmental factors along a transformation gradient, from natural protected areas to landscaped parks. Bird observations were conducted during winter (non-breeding season), spring (dry breeding season), and summer (wet breeding season). We used multi-model inference to assess the relationship of green space area, shape, isolation, tree richness, habitat diversity, and vegetation cover with species richness, Faith’s phylogenetic diversity, and functional richness. We calculated standardized effect sizes from null models to assess phylogenetic and functional structure. We registered 91 species belonging to 28 families across all sites and seasons. The number of detected species was largest in winter and decreased toward the dry breeding season, and then toward the wet breeding season. We found a moderate to strong positive relationship of species richness with phylogenetic diversity and functional richness. Overall, phylogenetic and functional structure of bird communities in green spaces was neither clustered nor over-dispersed. However, few cases of functional clustering, phylogenetic clustering, or both were observed, and they corresponded to natural protected areas. Results showed a predominant role of green space area in determining community diversity and phylogenetic structure while it did not influence functional structure. Contrary to our predictions, habitat diversity had a negative effect on species richness and phylogenetic diversity and this effect was detected only during the wet breeding season, whereas isolation showed a positive relationship with phylogenetic and functional structure, during the wet breeding season and winter, respectively. This study emphasizes the use of complementary measures of diversity together with the comparison between observed and expected values to get a better insight into the mechanisms by which green spaces’ characteristics affect bird diversity across the seasons.

“…Due to the wide diversity of environments and behaviors and, consequently, greater exposure to negative effects associated with habitat transformation, such as mortality from window collisions, exposure to new diseases and predators, birds have been used to study the effects of urbanization on the diversity of species (Carvajal-Castro et al, 2019).…”

Natural ecosystems are in constant conflict with the growing and disordered urban expansion, arising from the mismanagement of human developments and infrastructure, facing an accelerated rate of deforestation and defaunation. The intense pressure on natural environments impacts the local fauna through various incidents, generating high mortality, such as hit-and-run, window-crashing, attacks by domestic animals, dissemination of diseases and electrocution. The purpose of this study was to carry out a retrospective survey of the wild fauna rescued and treated at a clinic associated with the environmental police in the region of Joinville - SC. A total of 379 wild animals were treated at the clinic from 2014 to 2016. Of these, 262 (69.13%) were birds, 107 (28.23%) mammals, 9 (2.37%) reptiles and 1 (0.26%) amphibian. The main causes of referral for clinical care were due to trauma (50.66%), seizures (1.32%) and other causes (48.02%), such as home invasion and orphaned puppies. Among the reasons for traumas, pedestrian accidents were the most prevalent, representing 39.58% of the cases treated, followed by animals found to be debilitated without a defined cause (31.77%), attack by domestic animals (14.58%) and window-crashing (9.89%). The data obtained in this study show a rich diversity of species in Joinville. These species are exposed to several anthropogenic challenges and barriers derived mainly from intense displacement and human invasion, causing many animals to move in order to adapt to urban areas.
