Tropical forests around the world have been lost, mainly because of agricultural activities. Linear elements like riparian vegetation in fragmented tropical landscapes help maintain the native flora and fauna. Information about the role of riparian corridors as a reservoir of bat species, however, is scanty. We assessed the value of riparian corridors on the conservation of phyllostomid bat ass...

Materials and methods: In a descriptive cross-sectional study, 50 schools were selected by random sampling and the illuminance was measured using network method. In each place 2 to 10 measurements (between 8:00 AM and 14:00) were done using Lux meter (TES; A1336). Data was analyzed by GEE in SPSS V. 20. Results: The lighting intensity was measured in 306 places including 194 classrooms, 49 o...

Corridors are commonly used to connect fragments of wildlife habitat, yet the identification of conservation corridors typically neglects processes of habitat selection and movement for target organisms. Instead, corridor designs often are based on binary patterns of habitat suitability. New technologies and analytical tools make it possible to better integrate landscape patterns with behaviora...

Since the early 1970s, there has been a growing understanding that the form and function typical to many urban areas is unsustainable. Significant problems are evident in many urban areas today, such as air, water, and noise pollution, lack of green/open spaces, and inefficient transport systems. Given urban areas are home to around half the world's population, it is vital that efforts are made...

Trees in urban landscapes provide a range of ecosystem services, including habitat, refugia, food, and corridors for other fauna and flora. However, there is some debate whether the richness and abundance of other biodiversity supported is influenced by the provenance of trees, i.e., native or non-native. This study assessed the presence of mistletoes and birds (and nests) in 1261 street trees....

Coordinated actuated traffic signal systems have been widely deployed in urban and suburban areas as they provide progression along the major corridors. However, it has been often observed that uncoordinated cross street movements experience higher delay under the coordinated actuated signal systems due to their inability to adjust maximum green times (or force-off points). A few studies mentio...

Temporary aquatic environments are widespread in the world, and although there are considerable regional differences in their type and method of formation they have many physical, chemical and biological properties in common. With the aim to increase knowledge of urban temporary pool fauna, the objectives of this work were to assess the seasonal patterns of species composition, richness, and di...

The benefits of walking in natural environments for well-being are increasingly understood. However, less well known are the impacts different types of natural environments have on psychological and emotional well-being. This cross-sectional study investigated whether group walks in specific types of natural environments were associated with greater psychological and emotional well-being compar...
