Six major groups of enteric bacteria, viz, Faecal coliforms, E. coli, Shigella spp., Salmonella spp., Vibrio parahaemolyticus and Vibrio cholerae were screened for the present study. The overall percentage occurrence of enteric bacteria in water and sediment was maximum accounted for Vibrio parahaemolyticus (81.7%) and minimum for Salmonella spp. (9.6%) and moderate reported against Vibrio chol...

[1] This study presents vertical profiles of turbulence parameters obtained in the upper 100 m of the northeastern Atlantic Ocean along a transect from tropical permanently stratified waters to subpolar seasonally stratified waters in July–August 2009. The focus is to fully characterize the vertical mixing along this transect for further studies related to phytoplankton and nutrient distributio...

The white-fronted spider monkey, Ateles belzebuth, is listed as 'Endangered' according to the IUCN classification. In Peru it is found in the departments of Loreto, San Martín, Amazonas and Cajamarca, but detailed data on its geographic distribution, population densities and conservation status are scarce. In order to obtain such information, we conducted transect censuses on the Río Aushiri an...

Experimentally determined values of unsaturated soil hydraulic conductivity are presented for an Alfisol of the county of Piracicaba, S.P., Brazil. Simultaneous measurements of soil water content and pressure head are made along a 125 m transect within an irrigated field during the internal drainage process. Calculations of the soil hydraulic conductivity were made using the instantaneous profi...

Urbanization and loss of natural habitat has resulted in cities being identified as ecosystems capable of sustaining biotic communities and diversity. This study measured bird species diversity at Vadakkechira pond and surrounding areas during the period 2002-2009. This habitat is situated right in the heart of the city of Thrissur which is renowned for its historic importance and cultural extr...

We have conducted a detailed mineral magnetic study of loess unit 8 (L8) and paleosol unit 8 (S8) from three localities (Jingbian, Yichuan, and Duanjiapo) along a N-S transect in the Chinese loess plateau. As expected, the lowfield magnetic susceptibility (χ) has higher values in S8 and lower values in L8. Similarly, superparamagnetic particle concentrations increase in S8 with increasingly hum...

The aim of the study was to assess trace metal air pollution in the Beskidy Mountains, the Outer Western Carpathians, Poland, with a widely used bioaccumulating organism, a lichen, Hypogymnia physodes. Lichens were collected at five stands (mountains) in parallel transect and analyzed for cadmium (Cd), copper (Cu), nickel (Ni), lead (Pb) and zinc (Zn) content. Concentrations of Cd, Pb and Zn in...

By combining double-count and line-transect sampling data we obtained estimates of animal and group densities. The sample design consists of flying aerial surveys along elevational contours with two observers in the same platform searching the same region on one side of the airplane. Detected distances are not grouped, and factors such as size and activity of the group, and the extent of the ho...
