Diameter size class distributions of Pinus gerardiana Wall. ex D. Don from Gohar Abad Valley district Diamer, Gilgit-Baltistan, Pakistan

The present study was conducted to assess the diameter size class (Dbh) distribution of Chalghoza forest in Goharabad District Diamer. Data was collected from six different sites randomly using the PCQ (Point Center Quadrate Method) during July and August 2014. Study revealed that Pinus gerardiana Wall. ex D. Don is the dominant tree species of […]

Population assessment of Himalayan lynx (Lynx lynx isabellinus) and conflict with humans in the Hindu Kush mountain range of District Chitral, Pakistan

This paper is the first-ever attempt to outline the interaction of Himalayan lynx (Lynx lynx isabellinus) with humans and its abundance measured through motion triggered camera traps in Hindu Kush Mountain Range of District Chitral, Pakistan. The study was undertaken in December-January, 2011 for a period of 35 days with a total trap days of […]

Physico-chemistry characterization and zooplankton specific diversity of two fishponds in Yaoundé (Cameroon, Central Africa)

The specific composition and structure of zooplankton in two fish ponds (one being natural E1 and the other man-made E2) in Simbock, Yaoundé, was studied in relation to some physico-chemical variables, between April and December 2007. Physico-chemical parameters were measured according to the techniques described by APHA (1985). Biological analysis was done, using specific identification […]

Morphological and genetic variation in Aegilops geniculata Roth. from Tunisia

Aegilops geniculata Roth is an annual grass relative to cultivated wheats and is widely distributed in North Africa. In order to understand the diversity of this species, 13 populations collected in different bioclimatic areas in north and central Tunisian were analyzed using morphological and molecular characters. Principal component analyses (PCA) based on the agro-morphological characters […]

Effect of oil contamination on lead (Pb) concentration in muscle tissues of Otolithes ruber in Persian Gulf waters, Iran

In order to examine and compare Lead metal accumulation levels in muscle tissues of Otolithes ruber, sampling fish was done in both Bushehr and Asalouyeh stations during the summer 2013. After biometry of the samples, muscle tissues were separated and chemical digestion was done. Lead accumulation levels in tissues were measured by using a graphic […]

Responses of large wetland birds to human disturbances: results from experimental bird approaches in areas with different protection status in western Tanzania

Flight distances are quite often used to establish wildlife responses to humans. It is generally hypothesised that animals in protected areas are more sensitive to approaching humans than in areas where animals may coexist with humans at high densities. But this hypothesis may not hold true if animals are persecuted. A field experiment was designed […]

Role of earthworms against metal contamination: a review

Heavy metal contamination, occurring due to both natural and anthropogenic activities, is a subject of major concern throughout the globe. Increase in heavy metal content can have an adverse impact on functioning of the soil ecosystem by hampering the activities of soil fauna. Earthworms play an important role in metal pollution monitoring and are widely […]

Characterization of β-tubulin cDNA(s) from Catharanthus roseus

Vinblastine and vincristine are anti-tumor drugs produced by different species of Vinca. Vinca alkaloids depolymerize microtubules and as a result interfere with the normal formation of microtubules during cell division. Extremely low amount of vinca alkaloids in Vinca species and increased demand for chemotherapy are motives to scale up its production by biotechnological approaches. Here, […]

Quantification of betulinic, oleanolic and ursolic acid as medicinally important triterpenoids in wild and in vitro callus culture of Salvia sahendica (Lamiaceae): a comparative study

In the present study, quantitative determination of betulinic acid (BA), oleanolic acid (OA) and ursolic acid (UA) as well-known medicinal pentacyclic triterpenoids was simultaneously carried out in wild and in vitro callus culture of Salvia sahendica Boiss. Buhse (Lamiaceae) by reverse-phase high performance liquid chromatography (HPLC). The plant is an endemic medicinal species which is […]

On the annually recurrent of green macroalgal bloom phenomenon in Timsah Lake, Suez Canal, Egypt

Consequence macroalgae blooms phenomenon annually in Timsah Lake, the green macroalgal blooms phenomenon was increased in spring 2014 than the previous study in spring 2004 spring 2005 in order to cover large parts of El Taawen area at the south of Timsah Lake. Macroalgal species were growing firstly on the lakebed in the late winter […]
