An investigation was conducted to know the present status of fishing gears used and their species selectivity, length selectivity as well as their effects on fish biodiversity of the Chalan beel in Natore district for a period of 6 months from July to December, 2012. Interview schedules were used in collecting data from different upazilas […]
Biomass and Carbon Sequestration Rate in a Young Eucalyptus Hybrid Plantation of Terai Central Forest Division
Biomass and carbon sequestration rate in a 2 year old plantation of Eucalyptus hybrid was estimated in Terai central forest division of Uttarakhand over a one year period extending between October-2009 to September-2010. 20 permanent plots of 0.1 ha were placed randomly in the plantation site of 10 ha. The biomass was calculated by using […]

Mandibular shape variation among different size classes of the ant Camponotus sp.(Hymenoptera: Formicidae)
This study was conducted to determine shape differences in the mandibles of different size classes of the ant Camponotus sp.. To do this, landmarks taken from digital images of a total of sixty minor (30) and major worker (30) ants were subjected to the outline-based Geometric Morphometric Analsis of Elliptic Fourier Analysis (EFA). Results showed […]
Fluctuating asymmetry as an indicator of Ecological stress and Developmental instability of Neurothemis ramburii (Odonata: Libellulidae) in Iligan City, Philippines
Odonata species are often used for biomonitoring purposes are often influenced by environmental instability in diverse ways. The degree of developmental stability of individuals and populations is most often estimated by their level of fluctuating asymmetry (FA). FA refers to a slight number and nondirectional deviations from strict bilateral symmetry of biological objects that occur […]
Assessment of Leachate Quality by Comparing WQI to Saprobic Index in Plankton
Change on landfill function from sanitary landfill to open dumping at District of Mempawah, Western Borneo, Indonesia is deterioration in environmental management. Objective of this research is to assess leachate quality in dry season using a comparison of WQI to SI during tides. Only plankton species survives at specific contamination level in landfill leachate. Utilization […]
Spatial and seasonal variation of macrobenthos diversity around Nuclear Power Plant site, Tarapur, Maharashtra
The present study aimed at assessment of impact of Nuclear Power Plant site, Tarapur on macrobenthos diversity at seven locations, viz., TAPS 1&2, TAPS 3&4, Light house, Chinchani, Varor, Uchheli and Nandgoan for premonsoon, monsoon and postmonsoon seasons. Samples were collected for physico-chemical, hydro- sedimentological and macrobenthos study in intertidal area. The surface water temperature […]
Relative Warp Analysis on Shell Shapes of Faunus ater in Guihing River Hagonoy, Davao del Sur
This study aims to characterize the relative warp analysis on shell shapes of the Faunus ater. A total of 60 individuals were analyzed based on their shell shape and was deliberated using a landmark-based methodology. The following are the total landmarks stated and used: ventral/aperture=27, dorsal=17 and top of the whorl=147. Procrustes ANOVA showed the […]
Assessment of conservation status in Caspian Sea coastal area by the use of Diversity Indices
This research was conducted to investigate the plant species diversity in the protected and non-protected sites via comparison of biodiversity and similarity indices. The research area comprised a coastal system in the north of Guilan Province, Iran. Vegetation sampling was carried out along 16 shore perpendicular transects, approximately 500-m long. A total of 50 plot […]
Molecular characterization of Vibrio harveyi virulence-associated serine protease and outer membrane protein genes for vaccine development
Vibrio harveyi is the most pathogenic species associated with the infection in a wide range of marine species in aquaculture industries. A few virulence-associated genes have been discovered in V. harveyi. This study reports the cloning, sequence analysis and phylogenetic study of serine protease (VHS) and outer membrane protein (OMP) from a pathogenic V. harveyi, […]
