Background:Large-scale hunting and various anthropogenic pressures in the recent past have pushed the Asiatic caracal(Caracal caracal schmitzi),an elusive medium-sized and locally threatened felid species towards local extinction in *** widely distributed historically,it has been sparsely reported from several regions of central and northern states in India till twentieth ***,the species distribution became confined only to the states of Rajasthan,Gujarat and Madhya Pradesh,which have had reported sightings in the twenty-first *** order to highlight the potentially suitable habitats for Asiatic caracals in India,we targeted forth-filtering of the spatial model ensemble by creating and utilizing the validated and spatially thinned species presence information(n=69)and related ecological variables(aridity,NDVI,precipitation seasonality,temperature seasonality,terrain ruggedness),filtered with anthropological variable(nightlight).Results:Out of eight spatial prediction models,the two most parsimonious models,Random Forest(AUC 0.91)and MaxEnt(AUC 0.89)were weighted and *** ensemble model indicated several clustered habitats,covering 1207.83 km^(2)areas in Kachchh(Gujarat),Aravalli mountains(Rajasthan),Malwa plateau(Rajasthan and Madhya Pradesh),and Bundelkhand region(Madhya Pradesh)as potentially suitable habitats for *** probabilities of pixels were further regressed with converted vegetation height data within selected highly potential habitats,i.e.,Ranthambore Kuno Landscape(RKL)(suitability~0.44+0.03(vegetation height)^(**),R^(2)=0.27).The regression model inferred a significant positive relation between vegetation height and habitat suitability,hence the lowest ordinal class out of three classes of converted vegetation height was masked out from the RKL,which yielded in an area of 567 km^(2) as potentially highly suitable habitats for caracals,which can be further proposed as survey areas and conservation priority are

Characterization of Black Carbon in the Ambient Air of Agra,India:Seasonal Variation and Meteorological Influence

Advances in Atmospheric Sciences 2017年第9期34卷 1082-1094页

This study characterizes the black carbon in Agra, India home to the Taj Mahal--and situated in the lndo-Gangetic basin. The mean black carbon concentration is 9.5 μg m-3 and, owing to excessive biomass/fossil fuel combustion and automobile emissions, the concentration varies considerably. Seasonally, the black carbon mass concentration is highest in winter, probably due to the increased fossil fuel consumption for heating and cooking, apart from a low boundary layer. The nocturnal peak rises prominently in winter, when the use of domestic heating is excessive. Meanwhile, the concentration is lowest during the monsoon season because of the turbulent atmospheric conditions and the process of washout by precipitation. The ratio of black carbon to brown carbon is less than unity during the entire study period, except in winter （December）. This may be because that biomass combustion and diesel exhaust are major black carbon contributors in this region, while a higher ratio in winter may be due to the increased consumption of fossil fuel and wood for heating purposes. ANOVA reveals significant monthly variation in the concentration of black carbon; plus, it is negatively correlated with wind speed and temperature. A high black carbon mass concentration is observed at moderate （1-2 m s-1） wind speed, as compared to calm or turbulent atmospheric conditions.

Tuberculosis is one among top 10 causes of deaths worldwide. Access to effective diagnosis by every TB patient is one among five missions of Global Plan. Active case finding among vulnerable groups has been the key focus area of National Strategic Plan to control TB in India 2017-25. This cross-sectional study was carried out to find out the additional open cases of TB through active screening of general & rural population in selected villages of Jaipur, the capital district in Rajasthan state of India. An active screening team of trained staff visited each house-hold in selected study villages for interviewing the head of house-hold or other adult member available at the time of visit. Family members of age ≥ 15 years were screened for complain of chronic cough of duration 2 weeks or more with study questionnaire. Presumptive cases found at screening were referred for seeking medical consultations from nearest designated microscopy centre. The referred patients were followed up on telephone up to five times for results of medical consultancies. Laboratory technicians of catchment DMCs were also followed up for verification of results. Total 19,306 individuals were covered. Study included 52.8% male, 69.3% ≥ 15 years age, and 99.3% Hindu participants. There were total 153 presumptive TB patients. Out of these, total 10 cases were confirmed as TB. The yield of detection was 0.51 cases/1000 population screened. Study finds active screening as a feasible and effective strategy in detecting additional cases of TB from general and rural po
