Abstract The spatial distributions of biodiversity and people vary across landscapes are critical to the delivery ecosystem services disservices. high densities often birds in urban areas lead frequent human–avian interactions, which can be positive or negative for people's well‐being. identities bird species providing these disservices tend quite different; however, it is unclear how their abundance richness covary with human population density, hence potential recipients We surveyed populations 106 tiles (500 × 500 m) 174 km 2 an extended area southern England. From literature, we identified two groups species: those associated interactions well‐being that display behaviours estimated (adjusted detection probability) each group modelled they density.

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

PLoS ONE, Journal Year: 2019, Volume and Issue: 14(6), P. e0218775 - e0218775

Published: June 20, 2019

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

Influence of Land Use on Avian Diversity in North African Urban Environments

Published: April 18, 2021

Land cover and use changes are important to study for their impact on ecosystem services ultimately sustainability. In urban environments, a particularly research question addresses the relationship between urbanization-related biodiversity, subject controversies in literature. Birds an ecological group, useful answering this question. The present builds upon hypothesis according which avian diversity decreases with urbanization. order answer it, sample of 4245 observations from 650 sites Annaba, Algeria, obtained through point abundance index method, were investigated by computing Shannon-Wiener’s species richness, mapping them, analyzing results statistically. findings confirm relevant planning, as they stress role green spaces biodiversity hotspots, plead need connecting them. From planning perspective, emphasize interconnecting infrastructure corridors. Moreover, fill lack data region, other similar Mediterranean areas. Future studies could compare countries continents.

Abstract Elucidating bee response to urbanization is essential promoting pollinator diversity in cities especially considering such landscapes are projected expand support future global populations. To determine how community composition and plant–pollinator interactions respond urbanization, 29 sites representing three urban categories (high, medium low urbanization) were monitored biweekly from May through early October Toronto, Canada. Bees collected passively using pan blue vane traps as well actively aerial nets vacuums compare structure networks among categories. Functional traits dietary breadth, behaviour, nesting substrate native or non-native status also examined landscape influences assemblages. In total, 5477 bees, comprising 26 genera 164 species, represented this study. The was largely supportive of species within the family Apidae Halictidae ground nesting, generalist species. Overall, affected by characteristics percent tree cover impervious (i.e. paved built) surface surrounding sites; however, richness abundance significantly influenced plant not variables. A total 3267 observed throughout study region with remaining consistent along gradient a few floral host plants Solidago dominating certain contexts. These results provide important land use information for targeting conservation habitat restoration.

Due to the massive increase of urban population, a global target is achieve sustainable cities that are sensitive nature and environmentally just for dwellers. To accomplish this, it important understand responses native nonnative birds, identify environmental variables promote species limit species, how they vary among socioeconomic groups. Although many in Global South exhibit strong social segregation, few studies have investigated relationship between socioeconomics biodiversity. Therefore, help ecological justice biodiversity conservation developing world, we influence level woody cover on bird richness abundance city Santiago de Chile. We also whether response changes with provenance-it birds separately from because imply opposite management strategies (e.g., vs. control/eradication). Thus, surveyed 120 sites located residential areas high, medium, low levels across fit generalized linear (mixed) models described total, native, according vegetation cover. found both influenced community, but their effects changed origin, having birds.

The urbanization process modifies the environment in which wildlife lives. On one hand, it biotic and abiotic elements introduces new stress factors like light pollution, noise chemical pollution. These modifications to natural introduction of ones could induce organisms lead release glucocorticoids. One taxonomic group that lives cities is highly sensitive changes habitat human population density birds. Most studies about have measured glucocorticoids (GCs) circulating blood, offer only a “snapshot” an animal’s current state, affected by capture procedure. An alternative measure GCs samples are not altered procedure, feathers. In this study we compared levels corticosterone feather (Cort Feather ) southern lapwing ( Vanellus chilensis four locations Metropolitan Region (RM) Santiago de Chile. To accurately urbanization, employed distinct land cover typologies illustrate variations structural characteristics. A 500-m buffer zone was created around each collection sites where feathers were gathered, creating “Urbanization score”. We observed statistically significant variation median Cort values across studied localities. Contrary our expectation, differences concentrations identified among urbanized populations but rather between two characterized lower scores. same line, absence correlation score” levels.
