  • Melatonin Modulates Thyroid Hormones and Splenocytes Proliferation Through
           Mediation of Its MT1 and MT2 Receptors in Hyperthyroid Mice
    • Authors: Prashanjit Laskar; Shiv Shankar Singh
      Abstract: Abstract Hyperthyroidism is characterized by an increased metabolic rate with the alteration of immune activity. The pineal hormone melatonin regulates various physiological activities through sensitization of MT1 and MT2 membrane receptors in mammals. In the present study we have evaluated the involvement of MT1 and MT2 receptors in melatonin mediated modulation of thyroid hormones and splenocyte proliferation in experimentally induced hyperthyroidic mice. The l-thyroxine treatment induced the hyperthyroidism in mice evidenced with hypersecretion of T3 and T4 hormones from thyroid gland. Hyperthyroidic state increased the TSH hormone level which might be inducing hyper activity in thyroid gland. Exogenous melatonin suppressed the thyroid hormones level as well as TSH level in circulation. The l-thyroxine treatment increased the splenocyte proliferation and showed synergic effects along with melatonin. l-thyroxine treated mice alone or along with melatonin treatment showed differential expression pattern of MT1 and MT2 receptors protein in thyroid and spleen tissues. It seems that melatonin regulates thyroid hormones and splenocyte proliferation through activation of MT1 and MT2 receptors.

  • Ultra Structural Studies of the Septate Gregarine Phleobum elliptica Modak
           et al., 2011
    • Abstract: Abstract Genus Phleobum Haldar and Chakraborty, 1974 is one of the important genera of septate gregarine (Apicomplexa: Eugregarinida: Hirmocystidae), observed in the gut of grasshoppers. So far nine species of the genus Phleobum has been described but there is no report of ultrastructural study. The present study records the ultrastructural details of Phleobum elliptica inhabiting the gut lumen of the grasshopper Atractomorpha crenulata (Insecta: Orthoptera: Pyrgomorphidae). Under SEM, both the protomerite and deutomerite are found to be entirely covered with longitudinal, parallel pellicular folds, which are either straight or undulating in nature. A deep constriction is present at the junction of protomerite and deutomerite. Folds of the gamont are not continuous from the tip to bottom, rather interrupted at the region of septum. Protomerite bears protuberance like apical uplifted area, delimited by a deep groove. Association are caudo-frontal. Anterior end of satellite bears sucker like structure which receive the pointed end of the primate’s deutomerite.

  • Checklist of Benthic Macroinvertebrate Taxa Along Different Riparian Land
           Use Types in Alaknanda River Catchment of the Central Himalaya,
           Uttarakhand (India)
    • Authors: Jitendra Singh Rana; Bhaskaranand Semalty; Pranav Singh; Navneet Swami; Saurabh Dewan; Jagmohan Singh; Manju Prakash Gusain; Om Prakash Gusain
      Abstract: Abstract A checklist of benthic macroinvertebrates recorded at 08 different riparian land use (RLU) types in Alaknanda river catchment (ARC) in the Central Himalaya (India) is provided here. Among 77 taxa recorded, 73 insect genera belonged to 09 orders and 52 families at different RLU types. Majorities were nymphs and larvae of Ephemeroptera, Plecoptera, Trichoptera, Coleoptera, Lepidoptera, Odonata, Hemiptera, Megaloptera and Diptera. The highest number of insect taxa (50) was recorded from Dense Mixed Forest; whereas, the lowest (27) was recorded from barren site i.e., Montane Barren. Also, the forested site had most number of common taxa (25). Benthic macroinvertebrates at Chir Pine Forest serves as a link between Dense Mixed Forest and Open Mixed Forest. Agricultural sites had 36 taxa in common. Interestingly the agricultural sites share 24 taxa with the forested sites. Overall 13 benthic insect taxa were ubiquitous in ARC, while 15 were rare, confined to a single site.

  • In - Silico Construction of Phylogenetic Relationships Between
           Ampullariidae and Viviparidae Families (Gastropoda: Caenogastropoda) Using
           Partial Mitochondrial COI Sequences
    • Authors: Chittaranjan Jena; Krupanidhi Srirama
      Abstract: Abstract Freshwater biota especially molluscs are more vulnerable because even the slightest change in the quality of their habitat possibly leads to their mortality. In addition, their importance is felt that particularly molluscs contribute toward carbon sequestering from the environment as atmospheric carbon gets deposited as carbonates in their shell which constitute 10% of their body mass. Hence, the molecular phylogenetic relationships of two families inhabiting freshwater streams viz., Ampullariidae and Viviparidae considering the genera dwelling in Indian subcontinent namely Pila globosa and Bellamya bengalensis using the partial nucleotide sequence of mitochondrial COI gene were of considerable importance in building conservational strategies. The phylogenetic analysis of ampullariid and viviparid species inferred that these two chosen families were paraphyletic and rooted on the genera of Cyclophoroidea and possibly with Saulea vitrea as the connecting link.

  • On the Occurrence of Rusty-spotted Cat Prionailurus rubiginosus (I.
           Geoffroy Saint-Hilaire, 1831) (Mammalia: Carnivora: Felidae) in Odisha,
           Eastern India
    • Authors: Himanshu Shekhar Palei; Subrat Debata
      Abstract: Abstract Lack of scientific information encourages biased understanding on status and distribution of different species. The Rusty-spotted Cat Prionailurus rubiginosus is the world’s smallest felid endemic to India, Nepal and Sri Lanka. As much of its distributional range is falling outside protected area network, it is more vulnerable to loss and degradation of the habitat from anthropogenic activities. So, region specific baseline information is essential to reassess its status. In the present study, based on the Forest Department rescue records, we have reported its wide spread distribution in Odisha, eastern India. So, further targeted study in the identified localities is needed to generate baseline information on its status and ecology to develop appropriate conservation plans for future.

  • Composition of Avian Communities in a Human-modified Wetland Okhla Bird
           Sanctuary, India: With Notes on Conservation Initiatives
    • Authors: Subhendu Mazumdar
      Abstract: Abstract Monitoring of avian community composition in different landscapes are being emphasized from environmental monitoring perspective. Okhla bird sanctuary is an important bird area and has widest flood plains along the stretch of river Yamuna flowing through National Capital Region, India. At the same time, this sanctuary is under tremendous pressure particularly due to encroachment, unsustainable harvesting and pollution. Present study was carried out in Okhla bird sanctuary from July 2004 to June 2005 to assess the species composition and richness of the avifaunal community along with their seasonal variation. A total of 126 species belonging to 18 orders and 44 families were recorded. The avian species richness was highest for the order Passeriformes followed by Charadriformes, Anseriformes, Pelicaniformes and others. Anatidae was the most diverse avian family in the study area. Species richness of avifauna was highest in January (83 species) and least during July (37 species). This wetland supports good number of resident (86 species) and migratory birds (40 species). Most avian species (41.27%) were found to be wetland-dependent followed by wetland-associated (34.13%) and terrestrial (24.6%) birds. Kruskal–Wallis test revealed significant variation in the number of migratory and wetland-dependent species in different seasons. This study emphasize the importance of Okhla bird sanctuary for resident and migratory, as well as, terrestrial, wetland-associated and wetland dependent birds and thus contribute towards the existing knowledge of the seasonal pattern avifaunal composition of this wetland. Long-term monitoring of avifaunal composition over the years is an excellent means to assess the health of this waterbody and thus might be useful to foster its sustainable improvement.

  • Predatory Behaviour of Larval Alluaudomyia formosana Okada on Alluaudomyia
           xanthocoma Kieffer (Diptera: Ceratopogonidae)–Video Documentation
    • Authors: Sudipta Sarkar; Abhijit Mazumdar
      Abstract: Abstract The predation of adult Alluaudomyia upon several insects is well documented. However, the phenomenon of larval predation within the group is scant. The videos depict the predatory behaviour of larvae of Alluaudomyia formosana on Alluaudomyia xanthocoma within a petridish in the laboratory. The footages clearly demonstrate the mode of infliction of A. formosana on the intertergal membrane of A. xanthocoma with concomitant extradition of tissue fluids which led to death of the larvae.

  • Pan-Himalayan High Altitude Endemic Cliff Bee, Apis laborisa Smith
           (Hymenoptera: Apidae): A Review
    • Authors: Hiren Gogoi; Minam Tayeng; Meth Taba
      Abstract: Abstract The high altitude bee, Apis laboriosa Smith significantly differs from the close phylogenetic relative A. dorsata Fabricius in colour and shape of the abdomen, the endophalli of male genitalia, nucleotide sequence of the mitochondrial protein coding genes, chemical constituents of the cephalic and abdominal endocrine glands, nesting pattern, foraging and mating behaviour to distinguish them as separate species. They are found to construct single combed exposed nests under rock ledges in altitude ranging from 1200 to 3500 m above mean sea level from northern India to northern Vietnam. Current research trend shows the need of special attention for maximum possible and better quality agricultural and horticultural yield using A. laboriosa as it is known to pollinate a number of crops and fruits. General aspects of A. laboriosa to create sensitivity towards conservation of this species native to high altitude Himalayan foothills before being stressed by honey hunting, changing agricultural practices and crowding of natural enemies have also been focussed here.

  • Improvement of Growth and Survival of the Juvenile Walking Catfish,
           Clarias batrachus (L.) (Siluriformes: Clariidae) Fed on Probiotics
           Encapsulated and Ascorbic Acid Enriched Chironomid Larvae (Diptera:
           Chironomidae)
    • Authors: Atrayee Dey; Koushik Ghosh; Niladri Hazra
      Abstract: Abstract Effects of probiotics encapsulated and ascorbic acid enriched chironomid midge larvae as live feed on growth and survival of 12 day old Clarias batrachus juveniles (average weight 0.4 ± 0.06 g) were observed with feeding experiment for four weeks. Presumptive probiotic strains Bacillus aryabhattai KP784311, B. flexus KR809411, and B. cereus KR809412 were considered for bioencapsulation of chironomid larvae, and ascorbic acid (vitamin C) was used further for bioenrichment of the same. Seven experimental diets, D0: non-bioencapsulated and non-bioenriched chironomid larvae (control), D1: chironomid larvae bioencapsulated with B. aryabhattai, D2: chironomid larvae bioencapsulated with B. flexus, D3: chironomid larvae bioencapsulated with B. cereus, D4: chironomid larvae bioencapsulated with mixture of three strains, D5: chironomid larvae non-bioencapsulated and bioenriched with ascorbic acid, and D6: chironomid larvae bioencapsulated with probiotics and bioenriched with ascorbic acid were fed to triplicate groups. The juveniles were fed ad libitum for four weeks and the result of D6 group showed significantly higher (P < 0.05) specific growth rate and survivability than other groups. Although the RNA content in the carcass was increased initially in all dietary groups, any significant change of the DNA was not noticed. The coefficient (r value) of 0.992 in experiment 1 and 0.993 in experiment 2 along with regression slopes suggested a positive correlation (0.01 level) between RNA: DNA ratio and specific growth rate.

  • Determination of Chronic Median Lethal Concentration of Sodium Fluoride in
           Drosophila melanogaster and Exploring Effect of Sub-lethal Concentrations
           on Differential Hemocyte Count
    • Authors: Moumita Dutta; Prem Rajak; Sumedha Roy
      Abstract: Abstract The prerequisite for toxicity assessment of any chemical is the determination of its median lethal concentrations and thus, this study initiates with determination of chronic median lethal concentration of sodium fluoride (NaF) in a non-target organism Drosophila melanogaster, which was found to be 125–130 µg/mL. Further, chronic exposure to NaF at sub-lethal concentrations (10–100 µg/mL) resulted in significant reduction in total hemocyte number in general and plasmatocytes in particular, whereas, crystal cells were significantly increased in number. Since hemocytes are an integral part of innate immune system in Drosophila, their numerical fluctuation confirms fluoride-induced compromise in innate immunity status of Drosophila.

  • Biology and Biorational Management of Tuta absoluta (Meyrick)
           (Lepidoptera: Gelechiidae): A Global Challenge to Tomato Production
    • Authors: Jaydeep Halder; Deepak Kushwaha; A. B. Rai; B. Singh
      Abstract: Abstract South American tomato pinworm, Tuta absoluta (Meyrick), a native to South America, is an emerging exotic pest of tomato and other solanaceous crops in India. In Varanasi, Uttar Pradesh the pest was first observed on the month of January, 2017. Being an invasive pest, information on its biology and ecofriendly management under local conditions are essential. Under laboratory conditions the biology of the pest reveals that, the incubation, larval and pupal periods were 4.23 ± 0.57, 9.40 ± 1.05 and 8.90 ± 1.05 days, respectively. Adult females lived longer (15.98 ± 1.36 days) than the adult males (11.68 ± 2.99). Gravid females laid 79.40 ± 6.75 eggs, whereas egg viability was 83.30 ± 3.47%. Amongst the different biopesticides, Bacillus thuringiensis var Kurstaki was found most promising causing 66.7 and 73.37% mortalities at 48 and 72 h after the treatment followed by B. subtilis-2 and the corresponding values were 53.36 and 66.70%, respectively. The present study will be helpful in developing future integrated management strategies of this exotic pest in India relevant to Indian cropping systems.

  • Three New Species of Trichodina (Protozoa: Ciliophora) Isolated from
           Ornamental Fish, Carassius auratus from India
    • Authors: Mandira Saha; P. K. Bandyopadhyay
      Abstract: Abstract Surveys on the protozoan parasites of different ornamental fishes occurring in the farms of West Bengal, India during the year 2014–16 revealed that goldfish, Carassius auratus, was the most sensitive species for trichodinid infection. Three new species, namely, Trichodina indiana n. sp., Trichodina manjuae n. sp. and Trichodina vinodi n. sp. have been isolated and identified on the basis of dry silver nitrate impregnation technique followed by taxonomic description, morphometric variability and comparative data with its closely related species. T. indiana n. sp. has been uniquely characterized by their prominent denticular ring contains less angular acute denticle along with the large number of globular granules at the center of adhesive disc. Another two species T. manjuae n. sp. and T. vinodi n. sp. also described as new species, on the basis of their broad blade with extended well developed rays and sickle shaped, sharp denticle along with less prominent short rays respectively. The present study confirms the first report of this genus from Carassius auratus in India and added three more species under the genus along with new host, locality records and prevalence rates.

  • Probiotic Effect of Bacillus licheniformis fb11 on the Digestive
           Efficiency and Growth Performance in Juvenile Chitala chitala (Hamilton,
           1822)
    • Authors: Anisa Mitra; Pratap Kumar Mukhopadhyay; Sumit Homechaudhuri
      Abstract: Abstract Five isocaloric (430 kcal 100 g−1), isonitrogenous (40% CP) experimental diets were formulated with different concentrations of Bacillus licheniformis fb11 probionts (isolated from the gut of Chitala chitala) viz. Control (without probionts), 5 × 104 CFU g−1 (D1), 5 × 105 CFU g−1 (D2), 5 × 106 CFU g−1 (D3), 5 × 107 CFU g−1 (D4), 5 × 108 CFU g−1 (D5) to evaluate its efficiency in C. chitala juvenile. The best growth performance, feed utilisation, specific α-amylase, total protease and lipase activity were observed with the diet D3 (P < 0.05). The lowest Presumptive Pseudomonas Count, Motile Aeromonad Count, Total Coliform Count was observed for D3 (P < 0.05) on 90th day of trial. Two uppermost values were achieved in case of crude protein for D3 and D2 (P > 0.05). The highest lipid content (12.12 ± 0.4 g 100 g−1) was found for D5 (P < 0.05). The highest gross energy (18.75 ± 0.21 MJ 100 g−1) of carcass was recorded for D3. Thus B. licheniformis fb11 at the concentration 5 × 106 CFU g−1 as probiotic supplement promoted growth, digestion in C. chitala juvenile significantly by modulating intestinal microflora.

  • Black Tea ( Camellia sinensis ) Extract Induced Changes in Blood and Liver
           Parameters on Pregnant and Lactating Experimental Albino Rats
    • Authors: Avijit Dey; Antony Gomes; Subir Chandra Dasgupta
      Abstract: Abstract This study was to evaluate the changes in blood and liver parameters caused by oral dose of black tea extract (BTE) in experimental albino rats throughout pregnancy and lactation periods. Pregnant female Wister albino rats were chosen for this study. Group 1 was control group treated with saline. Group 2 and Group 3 were pregnant female rats treated with 50 and 100 mg BTE/kg/day respectively throughout pregnancy and lactation periods. All three groups of rats were provided with food and drinking water ad libitum. Animals were examined through their hematological profile, SEM of RBC and liver function test. BTE (100 mg/kg/day) produced significant alterations in hemoglobin concentration, total RBC and WBC count compared to control groups. BTE (100 mg/kg/day) also induced significant changes in the histology of liver and serum enzymes for liver function test compared to control groups. This study confirmed that BTE altered the parameters of blood and liver in pregnant and lactating experimental albino rats.

  • Natural Selection: A Misnomer Concept
    • Authors: S. K. Raut
      Abstract: Abstract Charles Robert Darwin hypothesized that the mechanism of evolution and the diversity of life on earth are because of natural selection. That is, which biological entity would thrive on earth is a matter of selection by the nature. But, in the present article it is hypothesized that the process of appearance of different types of biological entities and the orientation of these organisms in the space in respect to time are the effects of ‘will force’ of the organisms concerned. That is, the mechanism of evolution is a process of self selection, not natural selection.
