  • A Review on Reservoir System and Its Ecology in Indian Perspective
    • Authors: Moitreyee Banerjee; Joyita Mukherjee; Santanu Ray
      Pages: 5 - 20
      Abstract: Abstract Rural populations often depend on small reservoirs for their water supply. These are not natural aquatic system but are designed to serve specific purposes and provide the means to utilize water in a variety of useful and efficient ways. Water from these sources is not only utilized for drinking purposes, but also for commercial and industrial use. Though reservoirs are constructed, they are considered as an intermediate between a river and a lake. Thus limnological characteristics of this hybrid system have been of great interest to ecologists and researchers. Several limnological attributes regarding water quality, plankton abundance, fish population are been discussed in this review article. Ecological studies on global and Indian perspective are the major highlight of this review. A few modeling approaches are also discussed which are commonly used globally to preserve and manage the pristine aquatic nature of this hybrid ecosystem.

  • Impact of Urbanization on House Sparrow Distribution: A Case Study from
           Greater Kolkata, India
    • Authors: Biplob Kumar Modak
      Pages: 21 - 27
      Abstract: Abstract House Sparrow was the most abundant bird species near human habitat until few years back. But from the mid of twentieth century, the declining trend of House Sparrow has been reported from various countries. It has already been red listed in Netherlands and UK. Researches indicate the declining trend of House Sparrow in different cities of India like Delhi, Mumbai and Bengaluru. A 3-month wide survey has been conducted to get a preliminary idea about the distributional trend of House Sparrow in greater Kolkata. Depending on nature of urbanization and human habitat, greater Kolkata, has been subdivided into four regions (Planned City, Highly dense city, Medium dense city and Low dense city regions). In high density urban region the avian density recoded was highest, although avian diversity was maximum in medium and low dense city regions and minimum in planned city. Among 20 observational units of planned city region, House Sparrow has been noticed in 6 units and crow in all units. Among 115 observational units of rest of the regions of greater Kolkata, House Sparrow was observed in 79 units and crow in 98 units. The preliminary information revealed from this survey indicates towards negative relationship between urbanization and House Sparrow population in greater Kolkata and this negative influence is maximum in planned urban region. The presence of sufficient number of House Sparrow in any region indicates environmental stability of that region. So the declining trend of House Sparrow population in greater Kolkata, particularly in planned city region, indirectly gives the evidence of serious environmental degradation.

  • SAC and Berberine Mediated Repression of Reactive Species and
           Hepatoprotection After DEN + CCl 4 Exposure
    • Authors: Dipanwita Sengupta; Sujan Chatterjee; Tania Chatterjee; Kaustav Dutta Chowdhury; Priya Bhowmick; Udipta Chakraborti; Avik Sarkar; Soumosish Paul; Pradip Kumar Sur; Gobinda Chandra Sadhukhan
      Pages: 28 - 41
      Abstract: Abstract Oxidative stress is proposed to play a pivotal role in the development of hepatocellular carcinoma. With an accelerated metabolism cancer cells demand high reactive species accumulation to maintain their indiscriminate cell growth and proliferation. Here we wanted to see the status of reactive species in the chemically induced liver cancer. For this purpose swiss albino mice were exposed to DEN and CCl4 to develop an in vivo model of hepatocarcinoma. Depletion of cellular antioxidants regulated accretion of reactive species during the development of DEN + CCl4 induced tumor formation in hepatocytes. Currently available therapeutics for heptatocellular carcinoma is costly and coupled with certain bystander effects to the surrounding control cells. Therefore considering the antioxidant properties of SAC and berberine we treated DEN + CCl4 exposed mice after the development of liver tumor. Results effectively pointed out the usefulness of the alternative treatment with SAC and berberine in hepatoprotection. Replenishment of both enzymatic and non enzymatic antioxidant efficiently reduced accumulation of reactive species and that eventually closely associated with effective reduction in tumor number and size after drug treatment in DEN + CCl4 exposed mice.

  • Activity of Some Selected Hydrolases in Worker Honey Bees, Apis cerana
           (Fabr.). [Apidae:Insecta]
    • Authors: Sanjay Naiya; Narayan Ghorai
      Pages: 42 - 45
      Abstract: Abstract An API ZYM (Bio-Merieux, Lyon, France) test kit was used to examine the activity 19 hydrolases in in-hive bees and out-hive bees of worker Apis cerana. The study indicated that the activity of enzymes was changing in hypopharyngeal gland in in-hive and out-hive worker bees distinctly. The activities of most of the enzymes were observed. The protein hydrolases (acidic hydrolases) viz. leucine arylamidase, and valine arylamidase were more active in in-hive bees than out-hive bees. Rest of the tested enzymes were moderately present both in in-hive and out-hive bees. The hypopharyngeal gland and their secretion play important role affecting digestion of pollen, lipids and carbohydrates.

  • Biotic Potential of a Short-Horned Grasshopper, Oxya hyla hyla Serville
           (Orthoptera: Acrididae) to Assess Its Biomass Producing Capacity
    • Authors: Subhasish Ghosh; Parimalendu Haldar; Dipak Kumar Mandal
      Pages: 46 - 51
      Abstract: Abstract The growth of fishery and animal husbandry is being hindered by the scarcity of protein rich feed ingredients. Being rich in protein grasshoppers may be an alternative source of protein rich feed ingredients and hence rearing of these insects is essential for sustainable supply of insect biomass to the feed industry. The success of biomass production through insect rearing depends on the reproductive potentiality, rate of survival and growth of that particular insect. This study examines the biotic potential, fecundity, fertility, nymph mortality, life span and biomass production ability of a multivoltine grasshopper, Oxya hyla hyla (Serville, 1931) under semi-controlled condition. The grasshoppers are reared in 35 ± 2 °C temperature and 12L: 12D photoperiod and provided with food as fresh leaves of Cynodon dactylon (L.) Pers. to nymphs and Sorghum halepense (L.) Pers. to the adults. The result shows that a single pair of O. hyla hyla can lay on average 69.87 eggs in 4.96 ± 0.43 egg pods of which 7.37 ± 0.92 % eggs and 8.26 ± 0.99 % nymphs do not survive. The remaining survived nymphs metamorphose to 27.8 ± 3.35 male and 32.6 ± 3.21 female adults which produce a biomass of 18.48 ± 1.67 g wet weight. Thus a mass scale rearing of this insect may produce good amount of insect biomass which may be usable for fish and animal feed.

  • Body Indices of Garole Sheep Reared in West Bengal (India)
    • Authors: Sandip Banerjee
      Pages: 61 - 73
      Abstract: Abstract The study was conducted to assess some morphometrical traits and calculate structural indices of Garole rams and ewes reared at some selected villages of Joynagar, Mandirbazar and Mahishadal blocks of West Bengal (India). The results of the study indicated that the Garole sheep is reared under semi intensive condition sustaining by grazing on unimproved and degraded pasture, inundated lands or just besides the road sides. The results indicated variation across the studied locations for most of the traits studied, the variation was observed among both the rams and ewes. The observations of the structural indices indicated that most of the traits varied (P < 0.01 and P < 0.05), across the sex, age groups and studied locations, the results also pointed out that if selected Garole has a potential as a mutton breed. Therefore, immediate conservation and selection efforts need to be initiated to arrest the genetic dilution of the breed. The results of the cluster analysis indicated that the sheep from Mandirbazar and Mahishadal blocks have similar morphometrical traits which may be because the two locations are near to each other separated by the river Hooghly.

  • Characterization of the Bacillus thuringiensis Isolates Virulent Against
           Rice Leaf Folder, Cnaphalocrocis medinalis (Guenee)
    • Authors: Soumendranath Chatterjee; Syed Afrin Azmi; Tuhin Subhra Ghosh; Tushar Kanti Dangar
      Pages: 74 - 80
      Abstract: Abstract Soil samples were collected from different rice fields of Singur, Hooghly, West Bengal, India. Spore forming bacteria were isolated from the soil samples and among them, two isolates (BUSNC25 and BUSNC26) were larvicidal against third, fourth and fifth instar larvae of rice leaf folder, Cnaphalocrocis medinalis. The phenotypic, biochemical characterization and 16S rDNA analysis of the two isolates were done. On the basis of phenotypic, biochemical and phylogenetic analysis, the selected bacterial isolates (BUSNC25 and BUSNC26) were identified as Bacillus thuringiensis. The antibiotic sensitivity tests of these two isolates against selected doses of some standard antibiotics were done. Against the 3rd, 4th and 5th instar larvae of C. medinalis, the LC50 values of BUSNC25 were 2.45 × 104, 1.325 × 104 and 2.35 × 104 cfu/ml and of BUSNC26 were 3.375 × 104, 1.9 × 104 and 3.325 × 104 cfu/ml, respectively.

  • Bionomics of Momordica cochinchinensis Fed Aulacophora foveicollis
           (Coleoptera: Chrysomelidae)
    • Authors: Abhishek Mukherjee; Amarnath Karmakar; Anandamay Barik
      Pages: 81 - 87
      Abstract: Abstract The effects of feeding on root by the larvae and three types of Momordica cochinchinensis Spreng (Cucubitaceae) leaves (young, mature and senescent) by the adults of Aulacophora foveicollis Lucas (Coleoptera: Chrysomelidae) were studied under laboratory conditions. Total larval developmental time was 19.7 ± 0.2 days by feeding on young roots. Adult males lived for 28.4 ± 1, 65.7 ± 1.1 and 22.8 ± 1.3 days on young, mature and senescent leaves, respectively; whilst adult females lived for 34.3 ± 1.2, 68.5 ± 0.9 and 26.4 ± 1.4 days on young, mature and senescent leaves, respectively. Fecundity was highest in mature leaves fed insects (202.2 ± 10.6). Total carbohydrate, protein, lipid, nitrogen and amino acid were much higher in root followed by mature leaves than young and senescent leaves. Moisture content was highest in mature leaves than the roots, young and senescent leaves. Phenols were greatest in young leaves followed by mature leaves and least in senescent leaves and roots of the said plant. Flavonols were higher in young leaves and least in root. These results suggest that A. foveicollis adults perform better on mature leaves than young and senescent leaves for their nutrition.

  • Seasonal Trend of Body Protein and Growth of Chironomid Larvae
    • Authors: Susanta Nath; Rahul Podder; Biplob Kumar Modak
      Pages: 88 - 91
      Abstract: Abstract Chironomid midges technically named blood worms are known as useful live food for higher aquatic organism like fish. Present study deals with the seasonal variations of total body protein and the growth rates of chironomid larvae occurring in two water bodies of West Bengal, India. Analysis of the data revealed that the amount of body protein and the growth rate of larvae are higher during summer and monsoon. Comparative analysis of the data, indicates that the entire phenomenon depends on nutrient cycle of the water bodies which is influenced by a number of factors such as water temperature, alkalinity and soil organic carbon.

  • Clove Oil Efficacy on the Red Spider Mite, Oligonychus coffeae Nietner
           (Acari: Tetranychidae) Infesting Tea Plants
    • Authors: Archita Barua; Somnath Roy; Gautam Handique; Foridur Rahman Bora; Azizur Rahman; Dwiban Pujari; Narayanannair Muraleedharan
      Pages: 92 - 96
      Abstract: Abstract The tea red spider mite, Oligonychus coffeae Nietner (Tetranychidae), is an economically important pest of agricultural and ornamental crops and considered one of the major pests of tea plants in North-east India. In view of increasing resistance recorded in insect and mite pests against pesticides, a study was conducted to determine the acaricidal, antiovipositional, repellent and ovicidal activities of clove oil (an essential oil from the clove plant, Syzygium aromaticum L. Merr. & Perry: Myrtaceae) against tea-red-spider-mite. Mortality of O. coffeae varied with the concentrations and the duration of exposure time of the mites after application of oil. Rate of deposition of eggs by mites on treated leaf surfaces as well as the viability rate of eggs decreased significantly. In addition, certain concentrations of clove oil have been proved effective against adult mites.

  • Occurrence of Grey-headed Gliding Squirrel ( Petaurista caniceps ) in
           Arunachal Pradesh, India with a Note on Its Taxonomy
    • Authors: Murali C. Krishna; Awadhesh Kumar
      Pages: 97 - 99
      Abstract: Abstract Reports on the distribution pattern of Grey-headed gliding Squirrel Petaurista caniceps are distorted though it is on record that they inhabit the easternmost parts of Arunachal Pradesh. But recently through spotlight surveys in the month of February and March 2015 it has been possible to note their occurrence in Mehao Wildlife Sanctuary and Talle Wildlife Sanctuary in Arunachal Pradesh. P. caniceps is included as synonym to Petaurista elegans by IUCN. P. caniceps differs from P. elegans in having a distinct grey head and molecular evidences too have proved it to be a separate species.

  • Pollen Transport in the Dark: Hawkmoths Prefer Non Crop Plants to Crop
           Plants in an Agricultural Landscape
    • Abstract: Abstract In many previous studies hawkmoths have been found to be involved in nocturnal pollination of many plants. But their role in crop pollination is still unexplored. This study tried to evaluate their potential to carry pollens of crop. Hawkmoths were collected by light traps and slides were made from the pollen attached to their body. The hawkmoths and the pollens were identified. A pollen transport network was created using the data. The species level indices of each plant species in the network were estimated. Only a small fraction of pollens were made by the crops among the total types of pollens carried by the hawkmoths. Rest of the pollens belonged to that of the non crops. The species level indices suggest the crop pollens to be relatively less important in the network as reflected in the lower values of species degree and species strength. The higher species level specialisation values of crop pollens suggested they are restricted to be carried by few hawkmoth species only. It is clearly revealed that hawkmoths carry mostly non crop pollens, not crop pollens.

  • Effect of Toxic Heavy Metal Containing Industrial Effluent on Selected
           Life History Traits, Adult Morphology and Global Protein Expression
           Pattern of Drosophila melanogaster
    • Abstract: Abstract Accumulation of heavy metal laden industrial effluent into natural aquatic body leads to disruption of balance of that ecosystem as well as imperils the life cycle of the organisms living thereof. The present work aims to demonstrate the effect of toxic heavy metal containing industrial effluent on several life history traits, adult morphology and global protein expression pattern of insect model Drosophila melanogaster. Flies were reared for five generations in the effluent containing medium. One pair of virgin male and female fly from the stock was transferred to the vials. On the next day the male was removed and the female was transferred to fresh vials for successive days. Daily egg production of the females in different trials was recorded. Developmental time, pupation height, sex-ratio, egg-to-adult viability and mean body and wing length of the emerging flies from both treated and control groups were measured. We noted a drop in mean daily egg production rate, reduction in developmental time, shortening of pupation height, decreased egg-to-adult viability and a reduction in body and wing length in treated group in comparison to the control. However, no significant change was found in the sex-ratio of treated adult flies. Alterations in the expression pattern of body proteins in all the developmental stages were revealed by SDS-PAGE.

  • Threats to Fish and Fisheries of Kangsabati Reservoir, West Bengal, India
    • Authors: Amalesh Bera; Manojit Bhattacharya; Tapas Kumar Dutta; Mrinmay Ghorai; Shampa Patra; Bidhan Chandra Patra; Utpal Kumar Sar
      Abstract: Abstract Fishes belonging to the Orders Beloniformes, Cypriniformes, Perciformes, Siluriformes and Synbranchiformes are usually found in the Kangsabati reservoir of West Bengal, India. In recent years among the trapped fishes fishermen failed to get certain fish species which were available to them in the last decade. This prompted us to conduct a survey of ichthyofauna of the said reservoir in respect to the water parameters, keeping in view the anthropogenic activity-induced pollution scenario. It is revealed that the fishes belonging to the species Xenentodon cancila, Nemacheilus savona, Sillaginopsis panijus, Pangasius sutchi, Colisa sota, Mystus cavasius, Mystus seenghala and Mastacembelus armatus are completely absent in the survey area. It is most likely that the eutrophication-induced causes especially, variations in composition and density of plankton as well as the undesirable changes in physical and chemical properties of the water have forced these fishes to migrate elsewhere.

  • Selection Practices of Bonga Sheep Reared in Southern Ethiopia
    • Authors: Metsafe Mamiru; Sandip Banerjee; Aynalem Haile
      Abstract: Abstract The study was conducted to assess the traits traditionally used to select the Bonga sheep reared in Southern Ethiopia. The breed was included for improvement under the community based breeding program (CBBP) launched in the year 2009. The results are based on the data collected from the project between 2009 till 2012. The findings are based on focus group discussions with the community elders who have been rearing the Bonga sheep for more than 20 years. The present findings are based on information obtained from 50% of the total respondents who were involved in CBBP. The Bonga sheep is a mutton type breed and the ewes are moderately prolific. In the past this breed of sheep were bartered to settle legal disputes and were traded against household commodities.. However, over the years (and also after the intervention of CBBP) the sheep have been selected for their body weight as well as for their distribution in many parts of Ethiopia The respondents selected the lambs at both pre weaning and post weaning stages. Traditionally the traits of rams are selected based on their body length, canon circumference, broad face, enlarged thyroid, while for the ewes, traits prolificacy, skin thickness and pelvic width are determining characters. Fat tail and brown coat color were preferred irrespective of the sexes in trait selection. The ram lambs selected for breeding purpose are locally known as “Dookoo”. These rams are selected based on some predetermined phenotypic traits and are initially selected at preweaning stage and further, again at the post weaning stage. These rams are preferentially cared and are provided with supplementary feed and comfortable housing.

           amplexicaulis Leaves
    • Authors: Soumendranath Chatterjee; Amarnath Karmakar; Syed Afrin Azmi; Anandamay Barik
      Abstract: Abstract Extraction, thin layer chromatography and gas chromatography–mass spectrometry of Solena amplexicaulis (Lam.) Gandhi, commonly known as creeping cucumber, (Cucurbitaceae) leaves revealed 21 long-chain primary alcohols, and 100 g leaves indicated presence of 3651.59 ± 327.18 SE µg long-chain primary alcohols. 1-Heptadecanol and 1-triacontanol were the predominant and least abundant primary alcohols, representing for 780.44 ± 42.59 and 3.28 ± 0.55 SE μg, respectively. Antibacterial property of the complete synthetic blend (0.1%), comparable to long-chain alcohols as detected by GC-FID of 100 g S. amplexicaulis leaf extracts was evaluated on the pathogenic bacteria Salmonella gallinarum by agar well diffusion method, and exhibited 20.4, 26.7 and 38.2 mm zone of inhibition at 25, 50 and 100 μl doses, respectively. One hundred µl dose of 6 individual pure synthetic compounds, 1-tridecanol, 1-pentadecanol, 1-heptadecanol, 1-nonadecanol, 1-eicosanol and 1-tricosanol comparable to the amounts present in 0.1% solution of pure isolated alcohols from S. amplexicaulis leaves displayed 16.2, 17.7, 18.6, 22.8, 15.8 and 14.5 mm zone of inhibition against this bacterium, respectively. Hundred µl dose from a synthetic blend of above 6 compounds (comparable to the proportions as present in 0.1% solution of pure isolated alcohols from 100 g S. amplexicaulis leaves) exhibited 38.1 mm zone of inhibition against this bacterium. Furthermore, 100 μl dose from a mixture (1:1) comprising of chloramphenicol (1 µg/ml) and a synthetic blend of above 6 compounds displayed 38.8 mm inhibition zone against S. gallinarum, and hence, this combination might be used against this pathogenic bacteria.

  • Evolution: A Function of Will Force
    • Authors: S. K. Raut
      Abstract: Abstract Evolution is a gradual but continuous process. To explain the process of organic evolution different theories have been put forward by various authorities. But, all these theories are significant in respect to explanations of the possible mechanisms of evolution and certainly without acceptable analysis regarding the cause of initiation of evolution and the reason of maintaining the said flow all along. In the present article it is hypothesized that the process of initiation of evolution is initiated due to ‘will force’ and the said flow is being maintained because of ‘will force’.

  • Accumulation of Heavy Metals in Some Marine Fisheries Resources Collected
           from Gulf of Mannar Marine Biosphere Reserve, Southeast Coast of India
    • Authors: S. Rameshkumar; P. Prabhakaran; K. Radhakrishnan; R. Rajaram
      Abstract: Abstract Concentrations of toxic metals viz. mercury (Hg), cadmium (Cd) and lead (Pb) were evaluated in four species of fishes (Sardinella longiceps, Selaroides leptolepis, Epinephelus quoyanus and Lethrinus lentjan), one species of shrimp (Penaeus semisulcatus) and one species of crab (Portunus sanguinolentus) sampled from Thoothukudi, Keelakarai and Veerapandian pattinam of Gulf of Mannar, Southeast coast of India. Results revealed accumulation of these metals in the following order Hg > Cd > Pb. Hg concentration was found to be higher in Po. sanguinolentus followed by E. quoyanus, Pe. semisulcatus and L. lentjan however, the same was absent in Sa. longiceps and Se. leptolepis. Cd concentration was recorded in decreasing order in Po. sanguinolentus > Pe. semisulcatus > L. lentjen > E. quoyanus > Sa. longiceps > Se. leptolepis. Pb was detectable only in four species. Results of One-way ANOVA revealed significant variations (p < 0.05) in accumulation of Cd in Sa. longiceps, Se. leptolepis and Pe. semisulcatus and Hg in E. quoyanus, L. lentjan and Po. sanguinolentus. Variations noted in Pb were not statistically significant throughout.

  • Malcofaunal Diversity of Chilika Lake, Odisha, India
    • Authors: Debasish Mahapatro; Ramachandra Panigrahy; Sudarsan Panda; Rajani Kanta Mishra
      Abstract: Abstract Investigation during the period of 3 years from 2007 to 2010 on the malacofauna of Chilika lake revealed the occurrence of 126 molluscan taxa belonging to 56 families, 18 orders of three classes in the bottom sediment. Of these 61 species belonged to Bivalvia, 64 species belonged to Gastropoda and one species belonged to Polyplacophora. Maximum Bivalvia and Gastropoda taxa were found in the outer channel region of the lake. The dominating species were Crassostrea cuttackensis, Saccostrea cucullata, Brachidontes undulatus, Meretrix meretrix among bivalves and Cerethideopsilla cingulata, Bullia vittata, Nassarious stolatus, Indothias lacera, Natica tigrina, Turritella attenuata were from the gastropods. Occurrence of a large number of marine taxa is most probably associated with the opening of new lagoon during 1st August 2008.
