Bat data : Michigan, Detroit
Mist-netting was the survey technique over ultrasound-sensing because netting allowed for the elimination of repeat captures, which was required for statistical independence, and allowed for the determination of age ratios, ...
Binary linear programming models for robust broadcasting in communication networks : [data]
Output files showing optimal network configurations. Abstract from related article: Broadcasting is an information dissemination process in communication networks whereby a message, originated at any node of a network, is ...
Bat data : Australia, Adelaide City
Used echolocation call detectors (n = 378 detector-nights from November 2005 to October 2006) to assess bat activity among different sites in the Adelaide City parklands, temporal variations in activity (hourly, nightly, ...
Plant data : Germany, Halle (Saale)
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.
Bee data : Arizona, Phoenix
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 ...
Bee data : Canada, Vancouver
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 ...
Bat data : Brazil, Itabira
Each site was surveyed monthly from September 2004 through August 2005, between 18:00h to 1:00, totalizing thirty-six nights and 252 hours of capture. The bats were captured using four mist nets (9 m x 2.5 m), totalizing ...
Bat data : Australia, Sydney
Bat activity was sampled using the same study design as Threlfall et al. (2011), in 29 randomly selected replicate 5 5 km 'landscapes'. Landscapes were categorized based on the average level of urbanization and vegetation ...
Bird data - New Zealand, Dunedin
(Landscape and Urban Planning, 2008)
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 ...
Bird data : Brazil, Porto Alegre
Cities are highly modified environments in which the only areas that resemble natural landscapes are urban parks with low human population density. Attempts are frequently made to maintain high bird diversity in cities for ...
Bird data : Sweden, Örebro
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 ...
Bird data : Australia, Melbourne
