Selectivity and effectiveness of different gillnet mesh sizes used in ranau lake of Sumatra

Ranau Lake, the second biggest lake in Sumatra Indonesia, is inhabited by various freshwater fishes. The local people depend largely on fish resources for their life and use gillnet fishing gear for their fishing activity. The current research focused on selectivity and effectiveness of different gillnet mesh sizes as a tool to fisheries plan management […]

Vegetation diversity of dune slacks in Egypt

The present study intends to evaluate the dune slacks vegetation inside the sand dune ecosystem of Egypt. It represented by fives slacks in three different habitats: two brackish, two saline and one cultivated slacks in North Sinai. The density and cover of species were measured in 26 stands, 2X2 m2 each. The total number of […]

Presentation of flora, life forms and chorology of rural range plants in the North East Azarbaijan province, Iran

Floristic studies are fundamental for the applied sciences such as rangeland management and conservation. Unique ecological and climatic conditions in the North East Azarbaijan Province (NAP) make it a remarkable habitat for the floristic studies. Plant species were collected from 50 field sites, representing major habitats of winter and rural rangelands. Surveys were conducted during […]

Cassava green mite genetic diversity from three geographical sites in Kenya

Cassava green mite (CGM) of the Mononychellus genus is an invasive species in Africa introduced from South America. Its genetic diversity over geographical localities has never been assessed in Kenya. We extracted DNA on internal transcribed spacer 2 (ITS2) and cytochrome oxidase subunit I (COI) and compared phylogenetic variations of CGM from the three sites […]

Physical habitat simulation of Rainbow trout in mountainous streams of Iran

River physical habitat is defined as the variation of hydraulic parameters such as depth, velocity and bed cover in habitat condition of aquatic organisms. According to the previous studies physical habitat has considerable effect on habitat condition of different fish species. This study is carried out on a mountainous stream in Iran. In this research […]

Investigation into anthropogenic pressures and assessment of ethnobotanical insights regarding Berberis spp. across traditional landscape of Karakorum Mountain Ranges

Present study was aimed at assessment of anthropogenic pressures and documentation of ethnobotanical wisdom regarding Berberis species in traditional landscape of Karakoram Mountain Ranges. Cultural transformation has drastically declined ethnobotanical wisdom and human negligence and increasing pressures have made Berberis threatened (n=102; 27.3%). Using a stratified random sampling tools and techniques, 373 people were interviewed. […]

Effect of some climatic factors on insects associated with citrus agro-ecosystems in Ghana

The present study investigates the effects of some climatic factors on insects associated with citrus orchards in two different agro-ecological zones in Ghana. The study showed that, climatic factors affected insects differently in different agro-ecological zones. There was a negative and highly significant (P˂0.01) correlation between insect abundance and rainfall in the Coastal Savannah zone […]

Evaluation of human induced threats on berberis populations across cultural landscape of karakorum mountain ranges

Growing human and livestock population have negatively influenced Berberis populations across traditional landscape of Karakoram Mountain Ranges. Current study evaluates human induced pressures and threats on Berberis. One of a subspecies, B. pseudumbellata subsp. gilgitica has become critically endangered in the area. Moreover, .cultural changes underway have radically deteriorated ethnobotanical knowledge. Using a stratified random […]
