A comparison of terrestrial bird community structure in the undisturbed and disturbed areas of the Abijata Shalla lakes national park, Ethiopia
A study to determine the terrestrial bird community structures in the undisturbed and disturbed areas of the Abijata Sahlla Lakes National Park was conducted during the wet and dry seasons. A representative area of 57% was randomly sampled in each of the undisturbed and disturbed habitats. A transect line of 1 or less km at a distance of 50 to 100 m on one side of the line was used to count birds. Counting...

Vegetation dynamics of an old-growth lowland tropical rainforest in North-east India: Species composition and stand heterogeneity
The North East India forms an important hotspot of biodiversity by virtue of its unique biogeographical situation and healthier growing conditions. The region has an area of 13302.80 km2 under the protected area network (PAN), which is not yet systematically inventorised. In this paper, we investigated Namdapha National Park that comprises 14% of the total PAN of the region and forms the largest remnants of...

Biodiversity survey of trees and ornamental plants in Karunya University, Coimbatore, India
Biodiversity is the degree of variation of life forms within a given ecosystem, biome, or on an entire planet. Biodiversity is not consistent across the Earth. Western Ghats, older than the Himalayas, is one of the 34 global hotspots of biodiversity – flora, fauna, landscape and ethnicity. Western Ghats, anarrow 1,700 km strip that stretches from the mouth of Tapti in Dhule district of...

Essential sesquiterpene oil(s) in Khus-Khus (Vetiveria zizanoides Nash.) on roots diameter circumference positions for commercial usage
The culturing Khus in controled glasshouse condition in sand cultures for maximum essential monoterpene oil(s) was found (0.21%) in young developed middle position circumferences of roots. At middle position of leaf, net photosynthetic and contents of chlorophyll were affected. The maximum peroxidase activity was obtained at middle position of leaf and roots circumferances ...

The effects of soil characteristics and physiographic factors on the establishment and distribution of plant species in mountain forests (Case study: Asalouyeh, South of Iran)
The objective of this study was to assess the effects of soil characteristics and physiographic factors (slope, aspect and elevation) on vegetation distribution. We ultimately ascertained the most important characteristics on the establishment, regeneration and distribution of species in Asalouyeh mountain forests south of Iran. Vegetation sampling was performed using a randomized-systematic method and plot...

The management of alien species in India
Alien species, after becoming locally dominant, invade natural communities and become Invasive Alien Species (IAS). The impacts of exotic plants on community structure and ecosystem processes are poorly understood in India. A total 173 species in 117 genera are invasive alien plants, representing 1 % of the Indian flora. The agricultural economy in India is vulnerable to threat from exotic pests/ diseases. In...

Distribution patterns of cultivated watermelon forms in Zimbabwe using DIVA-GIS
Identification of potential areas and regions for collection of watermelon germplasm is pivotal for better utilization of the available diversity. DIVA-GIS were used on all watermelon collections in the National Genebank of Zimbabwe to explore the pattern of distribution of two forms of watermelons; sweet watermelon (Citrullus lanatus var. lanatus) and cow-melon (Citrullus...
