The leaf beetle (Coleoptera: Chrysomelidae) fauna of Mt. Manalmon in San Miguel, Bulacan, Philippines with reference to their host plants
Family Chrysomelidae is a highly speciose family that has been poorly studied in the Philippines. In this study, an inventory of chrysomelids was conducted in Mt. Manalmon within the protected area of Biak-na-Bato National Park located in San Miguel, Bulacan. Sampling was conducted seven (7) times in three (3) different elevations along vegetation within reach […]
Role of biotechnology in protection of endangered medicinal plant, Bunium persicum; the most important herb of Iran
Bunium persicum (Boiss) Fedtsch is a valuable medicinal plant that is facing extinction. A study was conducted to adopt various strategies and techniques to conserve and protect the biodiversity of B. persicum. Application of corm explant from six-month-old seedling on MS medium supplemented with various auxins showed that corm derived callus on MS medium supplemented […]
Effects of macrophytes on aquatic macro-invertebrates in urban polluted lentic ecosystem: case of the man-made lakes of Yamoussoukro (Ivory Coast)
Macrophtytes affect water resource utilisation, but little is known about its impacts on biodiversity in aquatic ecosystems particularly in Ivory Coast. This study allowed assessing the effects of macrophytes on aquatic macro-invertebrates in the urban lakes of Yamoussoukro. Macro-invertebrates were collected on twelve occasions at fourteen sites with macrophyte mats (Group 1) and at fourteen […]
The status of Lewis Glacier of Mount Kenya and the threat to Novel microbial communities
The disappearance of African glaciers is of great concern. Most important is the status of Lewis glacier, the smallest glacier in Africa that is rapidly melting. Lewis glacier is a well-documented tropical glacier that experiences a rapid retreat establishing deglaciated foreland. The steep elevation and lack of accumulation layer for Lewis glacier is a possible […]
Moss and lichen diversity in Mt. Kalatungan Range Natural Park, Bukidnon, Philippines
The study aimed to identify the mosses and lichens in terms of species richness and composition; document their distribution across different habitats; assess the conservation status; and identify several conservation strategies affecting the floral species and recognize its ecological importance in the ecosystem. Samples were collected through transect walk along the established 2-hectare biodiversity monitoring […]
An inquiry into the diversity of insect on rice cropping (Oryza sativa L.) at vegetative stadia applied by liquid organic pestisides derrived from plants and bio-slurry Biogas
This research is aimed at 1) comparing predator and pest composition on rice cropping treated by organic pesticides and bio-slurry biogas, 2) analyzing insect biodiversity on rice cropping treated by liquid organic pesticides derived from plants, 3) recognising the effects of plant-derived pesticides and bio-slurry biogas combination on insects biodiversity. This experiment was carried out […]
An updated plant inventory and biological spectrum of Tracheophytes flora of upper Tanawal area on western borders of Lesser Himalaya
The current work was executed in Upper Tanawal which is situated in the mid of Western fragment of lesser Himalaya. The study area is situated between 34°.34.40´ N to 34°.48.88´ N latitude and 72°.84.27´ E to 73°.10.50´ E longitude. Upper Tanawal is rich in biodiversity. Preliminary plant inventory was the first of any kind of […]
Freshwater molluscs distribution in relation to human activities in the Nakanbé Catchment (Burkina Faso)
Biodiversity contributes enormously to the well-being of communities. However, human activities threaten this diversity, especially in aquatic ecosystems. This work was initiated to show the impact of these activities on the diversity and distribution of some key organisms such as freshwater molluscs. Its objective is to show the influence of anthropogenic activities on the distribution […]
Spatial structure and abundance in the Kahuzi-Biega Mountain vegetation formation in DR Congo (Albertine Rift): Case of Carapa grandiflora SPRAGUE and Symphonia globulifera L. F. in the resort of Tshivanga
The present study was based on the study of the spatial distribution of two species, notably Carapa grandiflora and Symphonia globulifera, in the forest of the tourist site of Tshivanga in Kahuzi-Biega National Park on a surface of four considered habitats (hectares). In this study, we have used the nearest neighbor distance method to determine […]
Comprehensive appraisal of protected areas of Pakistan; their management status and encumbrance
Establishment of Protected Areas has long history and in recent years their development has accelerated across whole world to cope with the problem of biodiversity loss. Pakistan has also shown serious concern towards sustainable use of biological resources and cultural heritage by establishing legislation, policies and institutions. However implementation of these laws and policies is […]
