Assessment of population genetics of shisham (Dalbergia sissoo) based on genetic structure and diversity analyses
Population genetic study is an important strategy to shape up a scattered population, for its characterization and improvement. Marker assisted approaches have been allied to computation biology for unraveling and estimating precise genetic pattern of a population. Therefore, this research study was designed by keeping in view the lack of genetic information of shisham (Dalbergia […]
Variation of Palynomorphological and pollen production of some invasive plant species of Asteraceae family in conservation areas of tropical rain forest, West Sumatra, Indonesia
Some conservation areas in tropical forests of West Sumatra have been invaded by some invasive plants species from family Asteraceae. Characterization and pollen production of these plants are very useful to identify and clarify their invasiveness. This paper analyzed the ability of twelve invasive plants in producing the pollens, as determinant agents of reproductive biology. […]
Detection of cyanide in freshwater fishes relative to sex dimorphism using landmark-based geometric morphometrics in Agusan del Sur, Philippines
This study was done for public health and environmental concerns and aimed to determine the presence of cyanide in three fishes such as Channa striata, Oreochromis niloticus and Clarias batrachus, and described the allometry and sex dimorphism of Chevron Snakehead. The physico-chemical parameters, levels of Cyanide, Copper, Lead, Zinc and Iron in nine (9) stream […]
Antioxidant, antimicrobial activity and mineral profile of Moringa oleifera leaves extracts
This study was shaped to discover the antimicrobial, antioxidant and mineral profile of Moringa oleifera leaves extracts. The leaves crude extract was fractionated into different fractions using solvents of varying polarity. DPPH and FRAP methods were used to evaluate the antioxidant capacities of the extract fractions. DPPH scavenging activities were found in the range of […]
Green synthesis of silver nanoparticles using Lonicera quinquelocularis leaf extract exhibits antibacterial and antioxidant activities
Nanotechnology is a field that is mushrooming, having an impact in all circles of human life. Nano biotechnology represents an economic alternative for chemical and physical methods of nanoparticles formation. Presently available literature revealed that the NP synthesis using marine plants, microrganisms and algae as source has been unexplored and underexploited. The development of green […]
Length-weight relationship and condition factor of 13 fish species collected from the Atrai and Brahmaputra rivers, Bangladesh
Length-weight relationship (LWR) and condition factors (CFs) are imperative tools to discern the relative health condition of fishes. Using seine net, a total of 432 individuals (13 species) were collected from the Atari (Dinajpur) and Brahmaputra (Kurigram) Rivers of Bangladesh from January to June 2016. In LWR, isometric growth (b ≈ 3.0) were found for […]
Effect of citric acid supplementation on growth parameters of Cirrhinus mrigala fingerlings fed canola meal based test diets
Increasing demand with high price and unstable supply of the fish meal with the expansion of aquaculture made it necessary to search alternative protein sources. Due to higher pH of digestive tract, fish cannot absorb nutrients. Use of citric acid is beneficial for the absorption of nutrients by decreasing pH of digestive tract. Therefore, the […]
Structure and natural dynamics of Dodonaea viscosa communities in Malakand division, Pakistan
The present study aims to investigate the structure and natural dynamics of Dodonaea viscosa in Malakand division. For sampling a 10x10m quadrat was used and 28 stands were sampled. Various phytosociological attributes of the species were calculated. The IVI of 27 plants species was subjected to Cluster Analysis and Ordination which results into the formation […]
Comparative leaf morphometrics of two urban tree species: an assessment to air pollution impacts
Leaf-size indices of two urban tree species namely: Pterocarpus indicus forma echinatus Willd. and Sweitenia macrophylla King growing in polluted and non-polluted areas of Cagayan de Oro City, Philippines were compared to verify if air pollution could directly affect leaf morphology. The streets with the heaviest influx of vehicles per day were considered as the […]
Effects of different rainwater harvesting methods on the growth rate of Pistacia atlantica under rigid environmental conditions
Applying rainwater harvesting methods is very important in arid and semi-arid regions because of rigid environmental conditions and growth limiting factors such as low rainfall and its irregular distribution, high evapotranspiration, long dry season, wide range of temperature changes along the year and sever wind. In this research, effects of different rainwater harvesting methods on […]
