Opis:
The present study unfolds the diversity of ants of Bibhutibhushan Wildlife Sanctuary, North 24 Parganas, West Bengal, India. A total of 22 species under 13 genera distributed over 5 subfamilies could be recorded. These include three newly recorded species namely Leisiota frauenfeldi (Mayr) (Formicinae), Crematogaster (Acrocoelia) hodgsoni Forel (Myrmicinae) and Brachyponera nigrita Emery (Ponerinae) from the state and nearly 90.5% of the reported species are new for the district (marked*). Analysis of their zoogeographical distribution reveals that the fauna apart from being Oriental also includes some Palaearctic (72.73%), Australian (13.63%) and Ethiopian (4.54%) elements. The dominant functional group is constituted by the Subordinate Camponotini (36.37%) followed by Generalized Myrmicinae (22.73%), Tropical Climate Specialist (13.63%), Specialist Predator (9.09%), Opportunist (9.09%) and Dominant Dolichorinae (9.09%). Ants are mostly prevalent during Monsoon (81.82%), followed by Postmonsoon (68.18%) and Premonsoon (50.00%). Two species namely Camponotus (Tanaemyrmex) compressus (Fabricius) and Oecophylla smaragdina (Fabricius) are recorded throughout the year. Ranking sequence of the most abundant species in descending order is: Camponotus (Tanaemyrmex) compressus (15.01%) = Oecophylla smaragdina (15.01%) > Crematogaster (Acrocoelia) hodgsoni (12.91%). Camponotus (Tanaemyrmex) compressus and Oecophylla smaragdina are the most dominant species. Data also reveals that both core and buffer zones conjointly offer a better combination of habitat requirement, as 12 species are common in both the zones. Highest no. of species are recorded from leaf litter and ground combined together (22 species) and 6 species are arboreal in nature. Shannon’s Diversity Index (α diversity) and Simpson’s Diversity Index both are higher in buffer zone. This reflects the habitat exploitation efficiency of the encountered species. As per Jaccard Index (β diversity) the similarity value of both the zones is only 0.55.

Opis:
In the recent time there is an increase in the use of medicinal plants for treatment of ailments. This is owning to availability and low cost of herbal materials, which has increased the use of plants such as Viscum album for medicinal purposes. These plants may contain mineral elements, important phytochemicals and functional groups for healthy leaving, but increased use of this plant could lead to magnification of the mineral elements. Therefore, leaves of mistletoe (Viscum album) harvested from kola nut tree (Cola nitida) in Imo state, South Eastern Nigeria was studied. The study was aimed at determining the elemental content, phytochemicals as well as Fourier Transform Infra-red (FTIR) analysis of petroleum ether and chloroform extract of Viscum album harvested from Cola nitida. The sample for elemental analysis was digested with mixture of concentrated nitric acid (HNO3) and perchloric acid (HClO4). Petroleum ether and chloroform were used as solvents to extract the sample used for phytochemical and FTIR analysis. Elemental content analysis indicates that Ca, Cr, Cu, Fe, Mg, Mn and Zn were present at varying concentrations. The elemental content is in the order Fe > Mn > Cu > Mg >Zn > Cr > Ca. The presence of flavonoids, alkaloids, phenols, saponins and tannins were confirmed by the phytochemical screening. FTIR analysis indicates that alcohols, amides, aromatics and carbonyl compounds are present in the chloroform and petroleum ether extract of Viscum album harvested from cola nitida, though at different intensities. The presence of some essential minerals as well as some phytochemicals and some important functional groups must have necessitated the use of this plant for medicinal purposes.
