The Green and Blue Infrastructure (GBI) is a new approach for dealing with biodiversity conservation based on maintaining the ecological networks by ensuring survival of animal plant species. GBI considered public policy to avoid loss preserving landscape connectivity protecting natural habitats from fragmentation. Countries including United States, Canada, Kingdom, Italy, Portugal, Japan, Chin...

Leucocyte ascorbic acid (LAA) and serum ascorbic acid (SAA) have been estimated in 50 pregnant women, their newborn infants, and 14 non-pregnant women living in the semi-arid region of western India. LAA was significantly higher in the newborn as compared to their mothers, the mean values being 35.52 +/- 6.85 and 23.94 +/- 5.84 micrograms/10(8) cells, respectively (P less than 0.01). The sex an...

a new species of springtail (symphypleona, collophoridae), Collophora brasilis sp. nov., is described, the first species known from brazil. the species is distributed from the coastal region to the semi-arid region in northeastern brazil. it is characterized by the reduction in the trochanteral setae and teeth on the empodial complex. diagnostic features are illustrated and compared to other me...

The utilization of birds as pets has been recognized as one of the principal threats to global avifauna. Most of the information about the use and sale of birds as pets has been limited to areas of high biodiversity and whose impacts of anthropic actions have been widely broadcast internationally, for example for the Amazon Forest and forest remnants of Southeast Asia. The Caatinga predominates...

Estimating actual crop water requirement and irrigation schedule are essential for designing of the irrigation systems, storage construction and water conveyance structures. Many models have developed for estimating crop water requirement. Although most of these methods need different climatic parameters, providing and forecasting all of these parameters always are not available. Most of the ti...

Abstract The imbalance between water supply and demand highlights the vulnerability of many people prospect an uncertain future for supply. This work aims to compare Urban Water Security Index (UWSI) with three other methodologies (percentage flow duration curve, Sustainability Indicator, accumulated data from Drought Monitor) municipality Guarabira, Paraíba, Brazil. results show security based...

The Benanain Watershed is located in East Nusa Tenggara with an area of 3,181 km2 and divided into 29 sub-watersheds. itself eastern region Indonesia a unique climate condition called semi-arid. high rainfall intensity occurring short duration results large surface runoff erosion. Floods erosion semi-arid areas due to sensitive soils drought heavy extremely. This paper presents the application ...

Semi-arid ecosystems play a key role in global agricultural production, seasonal carbon cycle dynamics, and longer-run climate change. Because semi-arid landscapes are heterogeneous and often sparsely vegetated, repeated and large-scale ecosystem assessments of these regions have to date been impossible. Here, we assess the potential of high-spatial resolution visible band imagery for semi-arid...
