    Estimation of Mineral and Trace Element Profile in Bubaline Milk Affected with Subclinical Mastitis
    (Humana Press Inc., 2017) Singh, M.; Yadav, P.; Sharma, A.; Garg, V.K.; Mittal, D.
    The milk samples from buffaloes of Murrah breed at mid lactation stage, reared at an organised dairy farm, were screened for subclinical mastitis based on bacteriological examination and somatic cell count following International Dairy Federation criteria. Milk samples from subclinical mastitis infected and healthy buffaloes were analysed to evaluate physicochemical alterations in terms of protein, fat, pH, electrical conductivity, chloride, minerals (sodium, potassium and calcium) and trace elements (iron, zinc, copper and selenium). In the present study, protein, fat, zinc, iron, calcium and selenium content was significantly lower (P?

    The impact of invasive Hyptis suaveolens on the floristic composition of the periurban ecosystems of Chandigarh, northwestern India
    (Elsevier GmbH, 2017) Sharma, A.; Batish, Daizy R.; Singh, H.P.; Jaryan, V.; Kohli, R.K.
    We investigated the impact of invasive Hyptis suaveolens on the natural vegetation and soil of the periurban ecosystems of Chandigarh (Northwestern India), in terms of declines in species number, importance value index (IVI), richness, diversity, evenness, and changes in soil pH, conductivity and organic matter. The number of species declined by 46?52% in the areas massively invaded by H. suaveolens. The richness, diversity, dominance and evenness of species were severely reduced in the invaded areas compared to uninvaded areas. The reasons for this strong impact may be attributed to the vigorous growth of the weed in the invaded areas. Invaded areas were characterized by high cover of the exotic species. Several economically important species like Justicia adhatoda, Anisomeles indica, Carissa carandas, Dioscorea deltoidea, Murraya koenigii and Paspalidium flavidum were conspicuously absent in the invaded areas, though present in the uninvaded areas. Absence of these species in the areas invaded by H. suaveolens may pose socio-economic problems for the local people. Further, alterations were also noticed in the pH, conductivity, organic carbon and organic matter of the soil of invaded areas. Based on these observations, it was concluded that invasion of H. suaveolens has a marked influence on the vegetation of periurban ecosystems, and causes depletion of several economically important species. The present study calls for an immediate action for the management of this noxious alien weed. ? 2017 Elsevier GmbH
