The influence of building density on Neotropical bird communities found in small urban parks

Bird communities across varying landcover types in a Neotropical city

“…As urbanization is progressing rapidly throughout the biodiverse Neotropics (Pauchard & Barbosa, ), research on biodiversity assemblages in the urban areas of this region is growing increasingly important to inform local conservation priorities (Socolar, Gilroy, Kunin, & Edwards, ). Our study, one of only a few with an urban focus conducted in the Neotropics, demonstrates that many species are found within towns and cities, and reaffirms that urban bird assemblages are influenced by landcover type (Amaya‐Espinel et al, ; Dale, ; Fontana et al, ; Kang, Minor, Park, & Lee, ; Leveau & Leveau, ; MacGregor‐Fors et al, ; Pellissier, Cohen, Boulay, & Clergeau, ; de Toledo, Donatelli, & Batista, ; Villegas & Garitano‐Zavala, ). As the majority of land around Georgetown is agricultural, drawing comparisons with bird communities inhabiting natural landcovers in close proximity to the city was not possible.…”

“…Neotropical towns and cities are often characterized by extreme social and economic inequality, which in turn, may relate to the distribution and quality of urban greenspace (Boulton, Dedekorkut‐Howes, & Byrne, ). What little research there is on Neotropical urban birds has indicated that urbanization leads to reduced species richness (Amaya‐Espinel, Hostetler, Henríquez, & Bonacic, ; Reynaud & Thioulouse, ), an increase in overall abundance (Amaya‐Espinel et al, ; Reis, López‐Iborra, & Pinheiro, ), and larger populations of non‐native species (Amaya‐Espinel et al, ; Ortega‐Álvarez & MacGregor‐Fors, ). However, very few studies have examined the bird communities associated with different types of greenspace and bluespace within towns and cities.…”

Correlation Analysis between UBD and LST in Hefei, China, Using Luojia1-01 Night-Time Light Imagery

“…However, our comprehensive literature research found that past studies focused on the analysis of seasonal, daily, and annual variations of the UHI, which revealed the temporal and spatial variation of the UHI, the distribution characteristics of the horizontal and vertical directions, etc., while there has been less quantitative analysis of the single factors of UHIs, especially discussion of the ubiquitous relationship between impervious surfaces and UHI in the city.As an integral part of the urban impervious surface percentage, the urban building density (UBD) (percentage of built area) can directly reflect the degree of intensification and land-use efficiency in cities to some extent [11]. It is also an essential comprehensive social indicator that can function as an urban planning layout measure [12,13], resource utilization efficiency measure [14,15], and assessment of the urban ecological environment and livability [16][17][18][19]. Some researchers have pointed out that UBD is a crucial indicator to reduce the UHI effect [20] and proved a positive correlation between UBD and LST or UHI [21][22][23].…”

Conservación en la ciudad: ¿Cómo influye la estructura del hábitat sobre la abundancia de especies de aves en una metrópoli latinoamericana?

“…Un desarrollo urbano donde dominan las superficies impermeables y edificaciones afectaría a diferentes especies locales, disminuyendo la riqueza y abundancia de aves nativas (e.g. Silva et al 2015, Amaya-Espinel et al 2019.…”

“…Otras coberturas del suelo comunes en los ambientes urbanos, como pavimento y edificaciones, también influencian la abundancia de aves en la ciudad. En general, zonas con una alta densidad de construcción presentan una baja abundancia de aves nativas porque la calidad del hábitat sería baja para estas especies (Haedo et al 2017;Amaya-Espinel et al 2019). Sin embargo, algunas especies pueden ser más abundantes en sitios con una mayor densidad de edificaciones (Threlfall et al 2016, Morelli et al 2017.…”
