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 […]
Effect of salinity and prey algae on Artemia sinica (Anostraca: Artemiidae) growth and survival
The present investigation was carried out to determine the effects of two very important parameters i.e. salinity and micro-algal diets on the growth and survival of Artemia sinica. The animal was obtained in encysted form from Bohai Bay P.R. China, after 14 days constantly cultured (rearing trial) in laboratory with five different salinities. At the […]
Evaluation of ecological aspects of natural vegetation of Pakpattan District using multivariate techniques
A survey of natural vegetation, soil and water of Pakpattan District was undertaken in this study. Floristic data was analyzed by using multivariate analysis techniques i.e., Tow- way Indicator Species Analysis (TWINSPAN) and Canonical Correspondence Analysis (CCA). A total of fifty six species related to nineteen families were documented from forty quadrats in Pakpattan district. […]
Pastoralist experience and tolerance of snow leopard, wolf and lynx predation in Karakoram Pamir Mountains
Human-carnivore conflict is a common conservation and livelihood issue in mountain communities. This study was conducted to understand nature and extent of socio-ecological interaction between pastoralism and wildlife conservation in cold deserts of Karakoram Pamir Mountains (KPM) between China and Pakistan. Study revealed that livestock depredation is a burning issue in KPM with varying intensity […]
Kihansi spray wetlands under mitigation measures and its implication to the biodiversity of the resultant ecosystems
Originally, the Kihansi River Falls produced sprays that created microhabitat with high humidity and low temperatures. These microhabitats were the only habitats for Kihansi Spray Toad (KST) Nectophyrinoides asperginis, while adjacent forest supported other endemic species. However, in 1999 the Kihansi Hydropower Project diverted over 90% of the water from Kihansi River to the reservoir […]
Chemotaxonomy of four varieties of Mentha longifolia L. using essential oil composition markers
Mentha longifolia L. is one of the most important medicinal plant of Mentha genus. Studies were carried out to evaluate the chemotaxonomic relationships of four varieties of this specious. The evaluate oils were isolated and analytical gas chromatography was done. After determining 51 components, cluster analysis were used to determine the chemotaxonomy relationships between varieties. […]
On the incidences of oedipodinae (orthoptera: acrididae) from nara desert khairpur, sindh, Pakistan
A detailed survey for the collection of short horned grasshoppers were carried out during the year 2012-2013 from different localities of Nara desert i.e. Choondiko, Khehwari, Tajal, Sikandarabad and Jubo. A total of 322 specimens were collected and sorted into 6 genra and 8 species viz., Sphingonotus rubescens rubescens (Walker, 1870), S. savignyi (Saussure, 1884), […]
Coral disease prevalence in Samui Island and the adjacent islands, southern part of the Gulf of Thailand
Preliminary surveys for coral disease were conducted in April 2012 at shallow water reefs of Samui Island (Bang Po Bay and Thong Krud Bay) and four adjacent islands (Katen Island, Jatamoon Island, Mud Sum Island and Hin La Lek rock patch). Results showed that a total of 6 coral diseases were found consisting of White […]
