“…Urban areas shelter nearly 20% of the world's bird species (Aronson et al 2014), mostly in greenspaces (Ortega-Álvarez and MacGregor-Fors 2009). These species respond in different ways to urbanization, either by avoiding, tolerating or exploiting (Blair 1996;Marzluff 2001;Caula et al 2008;Shochat et al 2010;Evans et al 2015;Rayner et al 2015;Seress and Liker 2015;González-Lagos and Quesada 2017;Piratelli et al 2017;Murgui and Hedblom 2017). The occurrence of birds in urban settlements can be influenced by both the regional (e.g.…”

Many studies in urban landscapes have revealed that vegetation structure influences the taxonomic diversity and traits of birds and drives greater bird richness in greenspaces. However, most of these studies have been carried out mainly in public spaces. Private lands represent large components of cityscapes worldwide, and so understanding the role they play in the maintenance of biodiversity, and how vegetation traits drive the ecological attributes of birds, remain poorly known. Here we identified local factors of vegetation related to the bird fauna of urban private native forest fragments in Sorocaba, state of São Paulo, Brazil, with a focus on their ecological attributes. We predicted that increased vegetation structure would select birds that depend on forest environments and the resources they support. We sampled 13 vegetation traits in 28 private urban native forests to evaluate the relationship between vegetation structure and taxonomic diversity and functional traits of birds. Confirming our prediction, vegetation structure shaped the ecological attributes of birds, with five vegetation traits driving bird taxonomic diversity and functional traits, of which the number of standing dead trees was related to more bird ecological attributes. Vegetation structure in urban private native forest fragments may increase habitats and resources, thus supporting habitat-and feeding-specialist species. Our results provide insights for public policies aimed at management and maintaining vegetation structures that benefit bird fauna (e.g. number of standing dead trees, tree richness, canopy cover), in support of the ecological functions they perform in urban landscapes.

“…In the last two decades, some studies were conducted using birds in urban habitats of Latin America [14, 15, 25, 41, 42, 43, 44], but not all of them were in tropical regions. Thus, there is a gap in knowledge which still exists about the structure (i.e.…”

Birds vs bricks: Patterns of species diversity in response to urbanization in a Neotropical Andean city

et al. 2019

Urbanization is currently one the most important causes of biodiversity loss. The Colombian Andes is a well-known hotspot for biodiversity, however, it also exhibit high levels of urbanization, making it a useful site to document how species assemblages respond to habitat transformation. To do this, we compared the structure and composition of bird assemblages between rural and urban habitats in Armenia, a medium sized city located in the Central Andes of Colombia. In addition, we examined the influence of urban characteristics on bird species diversity within the city of Armenia. From September 2016 to February 2017 we performed avian surveys in 76 cells (250 x 250 m each) embedded within Armenia city limits; and in 23 cells (250 x 250 m each) in rural areas around Armenia. We found that bird diversity was significantly lower in urban habitats than in rural habitats, and differed in species composition by 29%. In urban cells, with higher abiotic noise intensity and higher impervious surface area, we found lower bird diversity than that in urban cells with higher guadual ( Guadua angustifolia patches), and forested surface areas. We did not find segregation of urban cells according to the species composition, although additional bird surveys inside urban forests remnant are needed to be more conclusive about this aspect. Altogether, our results highlight the importance of green areas embedded within cities to conserve bird diversity through reducing the ecological impact of urbanization on avian biodiversity.

“…The existence of urban forests in public avenues and squares could act as ecological trampolines or steppingstones, promoting dynamism for the animal species, which are the major responsible for pollination and seed dispersion (Lynch, 2019). Piratelli et al (2017) highlights that the creation of greener cities with higher species biodiversity will benefit the wildlife, as well as positively impacting the human life, making the cities healthier and more pleasant to inhabit. It is also important to incorporate a diversified pool of native species in urban forests, because they can promote an increase in the ex-situ conservation of species, since those species are also capable of releasing different resources in different phenological periods of the year.…”

Biodiverse neighborhoods: an ex-situ conservation tool

et al. 2022

Urban forests are responsible for a lot of benefits, and can be used as a tool to ex-situ conservation of native species. Our study investigated a public urban forest aiming to provide subside to management projects in order to allow the accurate fulfillment of social, aesthetic and ecological functions displayed by trees. Our survey was conducted in 6 public squares and 5 gardens in the Jardins neighborhood. We classified the trees according to their phytogeographic origins and seed dispersal habit. The Shannon-Weaver (H’) index, Simpson’s dominance (D’) and Pielou’s equability (J) were determined. A total of 507 individuals were sampled, located in 12 botanical families and 29 species, and 13 of them were classified as native and 16 as exotic. The family with higher species richness and number of species was Fabaceae (36%). Regarding the seed dispersal syndrome, the most representative was zoochory (52%). The ecological index showed medium species diversity (H’=2.2284), high dominance (D’=0.7899) and medium number of individuals (J) 0.6552. Although the Jardins neighborhood was planned, the urban forest in this area still needs improvement; such as incentive measures that can promote biodiversity and the application of ex-situ conservation.
