“…Our results were consistent with other studies and results from other cities showing that the Conservation Ecology 7(1): 5. http://www.consecol.org/vol7/iss1/art5 number of species declines with increasing urbanization and that the remaining group of species is dominated by highly abundant species (e.g., Emlen 1974, Campbell and Dagg 1976, Lancaster and Rees 1979, Edgar and Kershaw 1994. The patterns of urbanization, however, have rarely been examined in terms of the habitat mosaic, including both local-and landscape-level attributes characterized by gradient analysis (but see Blair 1996, Bolger et al 1997, Rottenborn 1999, Reynaud and Thioulouse 2000. In the present study, when we characterized the gradient to include mosaic composition, interesting community trends emerged.…”

“…Earlier studies acknowledged landscapelevel effects (e.g., Emlen 1974, Vale and Vale 1976, Lancaster and Rees 1979, but the complexity of the urban mosaic itself was difficult to characterize. We know of only a few studies that have examined urban bird communities citywide at different spatial scales (Haddidian et al 1997, Reynaud andThioulouse 2000). Thus, we chose the spatial-structuring approach to examine avian community composition in relation to features of the entire urban matrix.…”

ABSTRACT. For birds in urban environments, the configuration of local habitat within the landscape may be as critical as the composition of the local habitat itself. We examined the relative importance of environmental attributes (e.g., tree cover, composition, and number of tree species) measured at different spatial scales in relation to urban bird species richness and abundance. We expected that some bird species and nesting guilds would have a closer association with landscape-level features (within 1000 m), such as proximity to large forested areas, than with local-scale habitat measures (within 50 m). To investigate this, avian community data were collected at 285 point-count stations in 1997 and 1998 along four roadside transects located in Vancouver and Burnaby, British Columbia, Canada. Transects (5-25 km in length) bisected three large parks (>324 ha) and proceeded along residential streets in urban and suburban areas. In total, 48 bird species were observed, including 25 common species. Species richness declined in relation to a gradient of increasing urbanization, as measured by local-and landscape-level habitat features. We further examined the significance and importance of local-vs. landscapelevel habitat attributes using logistic regression and found that both scales explained the presence/absence distributions of residential birds. Local-scale habitat features such as large coniferous trees, berry-producing shrubs, and freshwater streams were of particular importance in estimating the likelihood of finding bird species. Landscape measures, particularly forest cover (within 500 m) and park area (measured at different scales as a function of distance from point-count stations) significantly improved likelihood estimations based solely on local-scale habitat features. Our results suggest that both local-and landscape-scale resources were important in determining the distribution of birds in urban areas. Parks, reserves, and the surrounding residential areas should be integrated into urban planning and development designs to maintain resident avifauna and overall species diversity in urban environments.

“…In this study, a series of rectangular windows moving along the urban-rural gradient and sector windows moving around the urban centre were integrated with landscape pattern metrics to quantitatively characterize the urbanization pattern of the metropolitan area of Beijing, the capital of China. Gradient analysis, developed in the context of vegetation analysis (Whittaker 1975), has been used to investigate the effects of urbanization on plant distribution (e.g., Kowarik1990; Sukopp 1998) and ecosystem properties (McDonnell and Pickett 1990;Pouyat and McDonnell 1991;Pouyat et al 1995;Zhu and Carreiro 1999;Reynaud and Thioulouse 2000). Using the gradient analysis, Luck and Wu (2002) and Zhang (2004) analyzed the landscape pattern in the Phoenix and Shanghai metropolitan areas, respectively.…”

SUMMARYQuantifying landscape pattern and its change is essential for monitoring and assessment of ecological consequences of urbanization. Using the GIS-based land-use data for 2002, we combined moving window analysis along an urban-rural gradient and around the urban centre with landscape metrics to quantify the spatial pattern of urbanization in Beijing. The results of moving window analysis along the urban-rural gradient indicated that, for class-level metrics, the spatial pattern of urbanization could be quantified using landscape metrics, different land-use types exhibited distinctive spatial signatures, and, for landscape-level metrics, the increase in urbanization in the metropolitan Beijing region has resulted in dramatic increases in patch density (PD), edge density (ED), and patch and landscape shape complexity, and sharp decreases in the largest and mean patch size (MPS), agriculture land-use type, and landscape connectivity. The results of moving window analysis around the urban centre showed that the direction of urbanization could be quantified using the class-level metrics, and landscape-level metrics indicated similar results to gradient analysis. In general, moving window analysis showed that the increasingly urbanized landscape became compositionally more diverse, geometrically more complex, and ecologically more fragmented.

“…From the opposing point of view, carnivorous [3,14] and insectivorous birds [3,12,15,[20][21][22] are considered at a disadvantage in highly urbanized areas, declining in both species richness and abundance. It is unclear if urban environments influence some other particular trophic group [4], because evidence shows that urban gradients in different cities may exert different effects in other trophic guilds [9,15,[23][24][25][26]. On the other hand, nesting patterns in breeding urban birds show two clear general trends: The most successful urban dwellers are characterized by i) showing cavity nesting behavior [3] and ii) building nests located a few meters above the ground or in the canopy [4,27].…”

Background: Current knowledge of urban bird ecology and biodiversity relies on evidence from cities of the Northern Hemisphere, while the Southern Hemisphere is underrepresented. Santiago is a large city from South America, located in central Chile, which is both a biodiversity hotspot and an Endemic Bird Area. This work is a synthesis, which aims to provide a diversity account for Santiago, and to describe the broad geographic distribution and bird functional patterns. Methods:We synthesized a seven-year (2009)(2010)(2011)(2012)(2013)(2014)(2015)(2016) bird register from the eBird database (21,865 georeferenced registers at Santiago) into a single avifaunal account, along with the observed number of individuals. We complemented these registers by using available literature about Santiago's avifauna (28 references). We investigated the proportion of native/ exotic, migrants/residents, conservation categories, and urban nesting status. We classified Santiago's birds into seven trophic guilds. We plotted species richness and number of individuals for each functional group, by interpolating trough the Inverse Distance Weighted Method. Results:We found that Santiago's avifauna (46 species) is composed mainly by native (41), resident (38), non-threatened species (46) that breed inside the city (31). Some functional groups inhabit a large portion of Santiago's urban surface, reaching high values of richness and abundance. Among these groups are the native, urban-nesters and resident species; even though exotics possess low species richness (5), they are abundant and inhabit the complete urban surface of the city. The dominant trophic guilds are omnivorous (11) and granivorous (10). Insectivorous are the third most abundant trophic guild, and show the highest species richness (13). Conclusion:The functional groups with lower species richness are less abundant and display reduced and patchy distributions in Santiago. This is probably because of the low availability of suitable habitats and/or restricted food supply (migrants, carnivorous, nectarivorous, frugivorous, herbivorous and piscivorous). The high insectivorous richness reported in Santiago, along with similar patterns reported in several cities in the Neotropics, provides evidence to postulate a pattern of high species richness of this guild in cities across this biogeographic realm.
