Bees were collected with water traps. Two pairs of bowls were set out per site,with members within a pair separated by 20 cm and pairs separated by 5 ill. Collected a total of 256 samples. Unscented liquid soap was used ...

Conducted a pilot study consisting of informal collections across the Vancouver metropolitan area from April to September of 2000. The primary study was conducted from March to August 2001, cut into five seasons: late ...

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 ...

Human activities cause drastic changes in the environment, such as the fragmentation of habitats, which is the greatest threat to the world's biodiversity and biogeography. By using birds to study habitat changes, it is ...

We studied the richness and composition of diurnal birds in relation to the percentage of built surfaces in an urban area of Mediterranean France and analyzed their seasonal variation. We recorded 61 species and identified ...

A functional network of green space is important for the maintenance of the ecological dimension of a sustainable urban landscape. We used avian ecological diversity as a proxy for evaluating the functionality of different ...

Few urban studies of avian diversity discriminate between native and exotic species, although highly modified urban environments typically support significant numbers of non-native species. High overall diversity may mask ...

Urban environments are often characterized as supporting a few abundant, generalist species best adapted to living alongside humans, and as such, cities are seen as agents of biotic homogenization. However, there are ...

Similar to the process seen in invasion biology, urbanized environments lead to biotic homogenization with a few species, often alien, dominating the urban habitat. We investigated avian communities across an urban gradient ...

Avifaunas of three large cities (Hamburg, Berlin and Warsaw) situated in the northern lowlands of Central Europe along an 850-km-long west-east line were compared. Estimates of several species’ breeding populations in these ...

This article examines the utility of particular bird species and guilds as bioindicators in a complex habitat mosaic, namely that of the tropical city of Cayenne (French Guyana). For this purpose, an urbanization gradient ...

All spontaneous species in the city of Halle (Saale) were mapped within several years by J. Stolle and S. Klotz; added by information on species sighted within the city by other botanists and added by herbarium data.
