Diversity and distribution of anuran in two islands of Parnaíba River Delta, Northeastern Brazil
The distribution and composition of communities are influenced by factors that determine the environmental characteristics in a particular region. In order to obtain more information regarding the fauna of frogs in the region of the Parnaíba River Delta, Northeastern Brazil, we performed a quantitative ecological study to compare the composition and distribution of the amphibian […]
Genetic polymorphism in Lens culinaris collected from malakand division Khayber Pakhtunkhwa, Pakistan
A major part of the human di et al over the world consists of cereals and legumes. Legumes are however, considered as the major source of protein and dietary amino acid for man and farm animals. The detailed evolutionary relations and cluster analysis in this group of plants may help in further manipulations and modifications […]

Fluctuating asymmetry study on the body shapes of Nemipterus japonicus in Surigao River, Surigao del Norte was conducted to indicate the environmental and aquatic condition in the area. Thirty four samples of N. japonicus were gathered, upon sexing there were 19 females and 15 males were sampled and collected. Threadfin Bream Fish was used in […]
Reptile Diversity in Mt. Matutum Protected Landscape, South Cotabato, Philippines
Reptiles are highly diversewith high percentage of endemism in the Philippines. However, reptile diversity in Mindanao, the second largest island in the country,is poorly known. To determine the species richness, diversity, endemism and conservation status of reptiles, this study was conducted from August to December 2013in six sampling sites of Mt. Matutum Protected Landscape (MMPL), […]
Mortality response of wheat aphid (Rhopalosiphum padi) against most commonly used insecticides in Pakistan
Rhopalosiphum padi is one of the most common wheat inhabiting pest and reduce the crop yield up to `15%. This pest species was collected from the wheat fields located in the vicinity of Faisalabad. The mortality response of said pest was find out in the different insecticides by standard nymphal dip method. The results showed […]
Assessment of allelopathic potential of different weeds on germination and early growth of aromatic rice
An experiment was carried out at the Department of Agricultural Chemistry, Bangladesh Agricultural University, Mymensingh during the period from July to November 2011 to investigate the allelopathic potential of different weeds on aromatic rice cv. BRRI dhan 50. Six weed species viz., joina (Fimbristylis miliacea), mutha (Cyperus rotundus), khude shama (Echinochloa colonum), sobuj nakful (Cyperus […]
