Effect of catenary differentiation on vegetation in Obung forest, Cross River State, Nigeria

The paper examined catenary differentiation of vegetation in Obung Forest, Cross River State of Nigeria. Specifically, it examined the effect of topographic variation on vegetation composition from the upper to the lower slope of the catena. Vegetation data basically tree density, tree species composition, family composition, stem diameter (dbh) and species dominance was obtained from […]

The floristic composition of the state Manipur falls under the Indo-Malayan type ranges from tropical to sub-tropical and temperate deciduous forests. It has rich floral diversity as well as high degree of endemism including a number of valuable medicinal plants. The Nagas and Kukis are the dominant hill tribal communities living in Senapati district. These […]

Study of plasmid linked resistance pattern of MDR enterobacterial pathogens

Ten multiple drug resistant enterobacterial pathogens were isolated from common sources of human consumption and were subjected to plasmid isolation. The multiple drug resistant (MDR)(write full abbreviation) isolates collected in the present study indicated the presence of plasmids of almost identical size of approximate 60 kb conferring resistance towards multiple antibiotics. An opportunistic pathogen Pseudomonas […]

Comparative determination of trace elements from Allium sativum, Rheum australe and Terminalia chebula by atomic absorption spectroscopy

In present study the bulb of Allium sativum, root of Rheum australe and fruit of Terminalia chebula were selected for trace elements analysis by Atomic Absorption Spectrophotometer. The plant samples were digested with concentrated Nitric acid (HNO3) and concentrated Perchloric acid (HClO4). The analysis for trace elements in the sampled plants indicated that Sodium, Potassium, […]

Allelopathic potential of Diospyros kaki L. against Triticum aestivum L., Brassica compestris L. and Trifolium alexandrinum L.

Allelopathic studies of Diospyros kaki L. were conducted by using aqueous extracts from leaves, bark, litter and mulching in various experiments. It was observed that the germination, radical growth, plumule growth, no. and growth of seminal roots, fresh weight and dry weight of Triticum aestivum L and Brassica campestris L. and Trifolium alexandrinum L. were […]

Mass flowering and death of bamboo: a potential threat to biodiversity and livelihoods in Ethiopia

Flowering and hence seed setting is the most infrequent phenomenon in most bamboo species. Seed setting in bamboos most often occurs gregariously for all the plants irrespective of age and/or location within and among populations. Seed setting in most bamboos is followed by total death of all the plants, which might havoc the whole ecosystem […]
