Four biological aspects of Schizodon nasutus in the low Sorocaba river basin, São Paulo, Brazil were analysed. These were accomplished during the year seasons. The fish diet and the feeding activity were investigated by studying the repletion index, which showed no significant differences between seasons. The food items analysed by frequency of occurrence and dominance showed a predominance of ...

Different methods have been designed to calculate the air quality index in form of mathematical formula. But the formula designed by Central Pollution Control Board in 2014 is more robust to find out the air quality category. The index has been calculated based upon four parameters like particulate matters (PM10, PM2.5), sulfur oxide and nitrogen oxide. The study area has affected by different ...

A cross-sectional survey of ticks infesting sheep was conducted in Sennar State, Sudan. A total body collection of ticks was carried out at five localities Sennar town, Singa, Dinder, Abu Naama and Um Banein on two types of Desert sheep (Watish and Ashgar) on two farms at each locality at two monthly intervals for one year starting July 2002 to May 2003. Four tick genera and eight species were ...

Australia as a continent represents semi-arid environment that is generally water-limited. Changes in rainfall pattern will inevitably occur due to rising temperatures caused by climate change, which has direct impact on the distribution of Australia's vegetation (green cover). As variability continues increase, i.e., frequency and/or magnitude, extreme events such droughts are predicted become...

newcastle disease is one of the most important diseases of poultry. it usually causes a great loss inpoultry industry and domestic village chickens. since domestic chickens in villages are free ranging for food,the chance of their contact with wild birds that may act as reservoirs is high. to determine the role ofdomestic chickens in the epizootiology of newcastle disease virus in villages of i...

Light-use efficiency (LUE) is the ability of vegetated canopies to use light for photosynthesis. Together with remote sensing estimates of canopy cover and meteorological inputs, LUE provides a physical basis for scaling carbon uptake processes from the stand to the global scale. A better understanding of the factors that control LUE will result in improved global estimates of carbon uptake fro...

Newcastle disease is one of the most important diseases of poultry. It usually causes a great loss inpoultry industry and domestic village chickens. Since domestic chickens in villages are free ranging for food,the chance of their contact with wild birds that may act as reservoirs is high. To determine the role ofdomestic chickens in the epizootiology of Newcastle disease virus in villages of I...

the gamasiab river has one of the highest discharge in the western iran receiving wastewater of trout frames. the present study investigated effects of wastewater using bioassessment of benthic organisms. the benthos were sampled over four seasons using a surber sampler on four stations, upstream, on the farm outlet, 500 and 1000 m down the farm outlet. 5454 benthic fauna were identified that w...

This study aimed to evaluate the effect of different nitrogen fertilizer sources and rates on morphophysiological characteristics use efficiency maize. The experiment was set in Campos Novos, Santa Catarina State, Brazil, during 2016/2017 2017/2018 growing seasons. experimental design a randomized block with treatments arranged split plots. Four were evaluated main plots: conventional urea, pro...
