A preliminary study on the animal diversity of Idukki Wildlife Sanctuary, Kerala was carried out with special reference to invertebrates for a period of fifteen days from 7th to 22nd January 2013. Various methods like line transect, point count, quadrate, pitfall trap, hand-draw net/towel and opportunistic observation were adopted for estimating the diversity and abundance. A total of 14 different animal taxa were observed which include mammals, birds, reptiles, amphibians, macroinvertebrates, spiders, butterflies, moths, ants, dipterans, hemipterans, orthopterans, hymenopterans, coleopterans and odonates. Out of the 34 species of mammals recorded six of them are new reports to the sanctuary. 104 bird species including four Western Ghats endemics such as blue winged parakeet, malabar grey hornbill, small sun bird and small green barbet could be recorded. Of the 20 reptile species recorded, Mabuya macularis was reported for the first time from the sanctuary. Out of the 29 amphibian type specimens observed, nine specimens were new reports, including Rana aurantiaca, Indirana leithi and Limnonectes limnocharis. Among the 84 species of butterflies sighted Danaid Eggfly (Hypolimnas misippus) Tawny Coster (Acraea violae), Large Oakblue (Arhopalaa mantes) Suffused Snowflat (Tagiades obscurus) Spotted Angle (Caprotted agamd) d Common Banded Awl (Hasora chromus) are new reports to the sanctuary. The study also resulted in documenting 33 macroinvertebrates including molluscs, arthropods, annelids and platyhelminthes, 87 species of spiders, 50 species of moths, 35 species of odonates, 50 genera of orthopterans, 25 genera of hemipterans, 37 genera of hymenopterans, 30 genera of coleopterans and 44 families of dipterans for the first time from the sanctuary. The present study indicates the presence of a very rich invertebrate diversity and the utmost need for conducting long term taxonomic studies to unveil the rich faunistic wealth of Idukki Wildlife Sanctuary.

Biological control of mosquito breeding has gained renewed interest owing to emerging problems associated with the use of synthetic pesticides. Amongst various biological control methods, use of larvivorous fish is best suited due to eco-friendly and self-sustainable nature. Poecilia reticulata (Guppy) and Gambusia affinis (mosquito fish) are popular exotic larvivorous fishes that have been successfully used for mosquito control in different parts of the world. The comparative efficacy of two indigenous fish, Esomus danricus (Indian flying barb) and Danio rerio (Zebra fish), prevalent in Assam, northeast India, and two exotic larvivorous fish species (P. reticulata and G. affinis) were reported in the given ecological context. Both the indigenous fish species were significantly (P

J Cell Tissue Res 2014, 14(2), 4211-18.
The environmental contaminants released into the aquatic ecosystem can disrupt the normal structure and functions of various organs in an organism thereby have an effect on its normal life. Octylphenol, one of the environmental contaminants, is known to perturb the normal functioning of aquatic life. In the present study octylphenol at 75μg/ L was exposed to freshwater fish, Oreochromis mossambicus for 7, 14 and 21 days and the biochemical changes and genotoxic potential was studied. During octylphenol treatment the body weights of the fish remained unchanged but the weight of liver and hepatosomatic index was decreased when compared to the control group. Octylphenol significantly increased mucous deposition all over the body in time-dependent manner. Biochemical estimation of the levels of lipid peroxidation, cytochrome oxidase and xanthine oxidase in hepatic mitochondrial fractions showed a significant increase at the end of treatment. This could be due to the generation of reactive oxygen species and energy demand in the mitochondrial fractions of hepatocytes. Exposure to octylphenol resulted in cytogenotoxicity as evidenced by fragmented apoptotic, bi-nucleated and sticky cells in micronuleus test and an increase in the number of colonies of the bacterium, Salmonella typhimurium, than that of control group. Therefore, octylphenol impairs antioxidant status and affects genotoxic potential when exposed chronically in freshwater fish O. mossambicus.

Study reports infanticide among stump-tailed macaques. The incident was observed when the study group was manipulated by introducing the á-male to the mother-infant pair at the breeding centre. As no copulation was observed between the á-male and the victim's mother, it was safe to exclude the á-male as the probable father. The infant was 14 months old and still suckling when she was killed. The after-math of the infanticide was a successful copulation and eventual conception by the victim's mother. This observation was found to be in accordance with the sexual selection hypothesis.

Present work reports the modulatory role of oxytocin on cortisol secretion by the interrenal cells in Clarias batrachus. Administration of dexamethasone @ 2.5 mg kg-1 body weight and captopril @8.3 mg kg-1 body weight for seven consecutive days resulted in a sharp fall in the cortisol level from 23.82 ± 1.248 μg dl-1 to 8.9 ± 3.47 μg dl-1. Treatment with oxytocin along with the above modulators resulted in an increase in cortisol level from 8.9 ± 3.47 μg dl to 12.84 ± 0.311 μg dl. Administration of oxytocin only, in the intact fish showed a stimulatory effect on the cortical production resulting in an increase from 23.82 ± 1.248 μg dl-1 to 31.9 ± 1.173 dl-1. The data were subjected to paired sample t-test and found to be significant at 95% confidence level. The present investigation clearly indicates a stimulatory effect of oxytocin in the regulation of cortisol secretion.

Curr Sci 2013, 104(8), 1083-6.
Reliable estimates of species density are fundamental to planning conservation strategies for any species; further, it is equally crucial to identify the most appropriate technique to estimate animal density. Nocturnal, small-sized animal species are notoriously difficult to census accurately and this issue critically affects their conservation status. We carried out a field study in southern India to estimate the density of slender loris, a small-sized nocturnal primate using line and strip transects. Actual counts of study individuals yielded a density estimate of 1.61 ha-1; density estimate from line transects was 1.08 ha-1; and density estimates varied from 1.06 ha-1 to 0.59 ha-1 in different fixed-width strip transects. We conclude that line and strip transects may typically underestimate densities of cryptic, nocturnal primates.

J Cell Tissue Res 2014, 14(2), 4219-26.
Study evaluated that bisphenol A induces oxidative stress to the exposed fishes by time-dependent reduction in the antioxidant enzymes and concomitant increase in the lipid peroxidation in the gill of Oreochromis. A significant reduction in the marker enzyme, succinate dehydrogenase (SDH) was also observed and this could be due to the impairment of aerobic metabolism in bisphenol- A treated fishes. Exposure to bisphenol- A for 20 days caused principal alterations in the gills of treated fishes as destruction of primary and secondary lamellae, upliftment of gill epithelium, hyperplasia and vasodialation in the lamellar epithelium. Thus the present study summarizes that the increased production of oxygen free radicals due to the exposure of bisphenol A inhibited the activities of antioxidant enzymes and succinate dehydrogenase thereby inducing oxidative stress and also destruct the normal architecture of gill in the fish.

Indian J Geomar Sci 2014, 43(2), 289-96.
A phytoplankton bloom dominated by Chaetoceros spp. was detected in the Arabian Sea, off Cochin coast during May 2009 coinciding the onset of southwest monsoon with an average chlorophyll a concentration of 8.42 mg m-3 at four stations (A, C, D & E) of total 7 stations studied in coastal waters situated between latitudes 9°54'-10°02' N and longitudes 76°05'-76°12' E. All the stations were resampled after seven days and found that the average chlorophyll aconcentration at the bloom stations has decreased to 2.91 mg m-3. The inherent optical properties (chlorophyll a, specific phytoplankton absorption coefficient, chlorophyll scattering coefficient) of water were analyzed from the study area. The physico-chemical parameters like dissolved oxygen, pH, turbidity and nutrients were estimated for surface waters in these stations using standard methods. The phytoplankton of the study area was identified and their density was recorded. The phytoplankton community composed primarily of diatom Chaetoceros sp. in all the stations, with a percentage composition greater than 55 at the bloom. The highest phytoplankton density recorded was 4,89,578 cell no./l at station D. Samples from the bloom showed higher specific phytoplankton absorption coefficient [a*c(λ)]than other stations. a*c(435) varied from 4.11 to 5.68 m2mg-1 and a*c(665) from 1.45 to 1.80 m2mg-1. A survey on purseseine fishery showed a higher pelagic catch in close proximity to the bloom area during this period. Further investigation of absorption properties of blooms using remote sensing at complex case II waters is needed to interpret bio-optical properties as well as fisheries. The present study is the first attempt of this kind off Cochin coast.

Studies on breeding periodicity of Liza macrolepis inhabiting Mangalore waters indicated that this species spawns only once in a year over a period extending from June to November with a peak during July to August. Data on the size at first maturity of Liza macrolepis using cumulative frequency method showed that male attained first maturity at 223.64 mm T.L., while the female at 236.36 mm T.L. Male always recorded lower Gonado-Somatic Index (GSI) values than female due to higher ovary weight compared to testis. The GSI values were high during June to November with peaks in July and August indicating the spawning period of this fish. The fecundity of fish ranged from 1, 22,278 to 6, 74,232 eggs, with an average of 2, 84,146 eggs. Log linear relationships were established between fecundity and total length, fecundity and body weight of the fish as well as fecundity and gonad weight. The sex-ratio of male to female was 1:0.85. There was an overall male dominance in the population.

Indian J Fish 2013, 60(2), 59-65.
Two morphologically similar species of whiting, Sillago sihama and Sillago vincenti were genetically characterised on the basis of their RAPD profiles, 12s and 16s rDNA sequences and their PCR-RFLP profiles. The RAPD profiles, developed by three random primers, OPA-12, OPB-12 and OPF-17, revealed 52.63% polymorphic loci in S. vincenti and 31.58% in S. sihama. The average genetic diversity within species (Hs) was 0.188±0.1574 and Gst (coefficient of gene differentiation) was 0.4397. Average genetic divergence between species was 0.4397, as expected for two different species of a genus. Partial 12s and 16s rDNA sequences were amplified and sequenced from both species, using primers reported previously for brackishwater fish species. Distance measure showed more differences between the 12s rDNA sequences (D=0.135) compared to the 16s rDNA (D= 0.0742). Digestion of 12s rDNA amplicon with Hind III and digestion of 16s rDNA with Sma I generated distinct PCR-RFLP profiles for the two species and that can be used for the identification of the species.

Indian J vet Anim Sci Res 2014, 43(3), 229-35.
Diet of mud crab S. tranquebarica consists of crustaceans, mollusks, fish remains, detritus, debris and undigested flesh. Quantitative analysis of the gut contents contributed 53.18% crustaceans, 24.69% molluscan remains, 16.91% fish remains and 3.02% & 1.23% of detritus and debris respectively. The study indicated that this species is primarily predators of sessile and slow moving benthic macro invertebrates. The presence of detritus, debris and undigested flesh items in the stomachs suggested that the crabs are detritivorous consuming fresh and decaying flesh of all kinds. The sex wise and size wise of diet in these crabs may be largely due to relative abundance of prey species in the habitat or related to change in cheliped strength and foraging behaviour.

The morphological characters like shape of teeth, nasal apertures, gill rakers and scales of trigger fishes collected from southern India were studied during the period 2000-2002. Based on the shape of the first and second teeth of the upper and lower jaw, five types have been identified. The anterior nasal aperture has different shapes, which is species specific but the posterior aperture is similar in all species. Based on the shape of the anterior nasal aperture, five types have been identified. The outermost branchial arch possesses gill rakers and based on shape they are divided into five types. Scales on body and caudal peduncle are diamond shaped, whereas scales on cheek are rhomboid, rectangular, square or triangular occurring in different combinations. The arrangement of scales on body, abdomen and caudal peduncle were similar in all the species studied while scales are arranged in three patterns on cheek. Scales on cheek are of seven types based on shape of the scale and type of protuberances it possessed on the posterior margin. Body scales are of five types and scales on abdomen are of three types. Transverse section of body scales under the scanning electron microscope (SEM) revealed that the scales consist of four layers. Studies on the ultrastructure of the anterior margin of the body scales revealed that there are five types; based on the type of protuberances it possesses and there are of four types of posterior margin.

Birds have preferences while selecting a habitat. Habitat may be defined as the place where an organism lives or the place where one would go to find it. In the present study, it was found that birds utilze each of the habitat in diferent ways depending upon what aspect of their equirement was met there. 45 uncommon bird species with low population at four diferent study areas were selected for habitat study. Bird showed habitat preferences. The various habitats under study were used by birds for diferent purposes, some for feding or nesting, other for osting or perching, or even as temporary resting place while pasing through. Data on the habitat requirements of a species could be useful for predicting the efects of habitat alteration due to human or natural communites. Habitat preference of a species might limit its dispersal and subsequent colonization. It is presumed that species restricted to a habitat would be relatively infrequent in a geographical area and its geographical range would be restricted. Its presence depends on the ocurence of a specific habitat in that area. On the other hand, generalist species would be common, occuring over a large area.

Biosci Biotechnol Res Asia 2013, 10(1), 333-7.
Anopheles mosquito is also capable of transmitting filarial worms, various arboviruses, onyong-nyong, tataguine, equine encephalitis, as well as other viruses, but malaria is unquestionably the most threatening disease. It has also resulted in the development of resistance, undesirable effects on non-target organisms and fostered environmental and human health concern, which initiated a search for alternative control measures. The bioinsecticides are generally pest-specific, readily biodegradable and usually lack toxicity to higher animals. This study was undertaken to investigate the larvicidal potential of the two different seaweeds Enteromorpha flexuosa J. Agardh and Gracilara corticata J. Agardh against the medically important species of malaria vector Anopheles. Of the two algae screened G. corticata was found to effective against the larva A.stephensi. It is concluded that the seaweeds such as E.flexuosa and G. Corticata serves as an excellent biopotent, which can be exploited for larvicidal property and can be cultivated in the coastal areas of the South East Coast of India.

Effect of azo dye AR-97 on embryos of Cirrhinus mrigala was studied by static bioassay tests with daily renewal of test water. Embryos were exposed at early blastula stage and 96 hour LC50 of dye was worked out to be 31.51 mgL-1. An increase in hatching time was observed with increase in concentration of dye. Maximum hatching time was 17.50 hours in control water and 38 hours in 50 mgL-1 concentrations of dye. In higher concentrations of dye hatchlings could not break the egg membrane and died unhatched. Hatchlings showed abnormalities like curved tail, ruptured yolk sac and improper development of head, eyes and tail. Percentage occurrence of abnormalities in hatchings increased with increasing concentrations of dye. Behavioral changes like restlessness, erratic movement, lateral swimming and hanging intensity were observed in hatchlings. SAR values of dye shows that dye in concentration higher than 1.939 mgL-1 is not safe for disposal. This study necessitates the treatment of dye before release into water bodies.

Bombyx mori L(Lepidoptera Bombycid) which feed on mulberry leaves are widely used for silk production. The Bombyx mori is one of the most thermal sensitive organisms. Heat shock proteins were presumed to ensure survival under stressful conditions by involvement in damage protection or damage repair due to their action as molecular chaperons. Heat shock proteins (HSP) are expressed in response to various biological stresses, including heat, pressure and UV radiations. The effect of heat shock in the whole larvae on various physiological parameters and proteins of haemolymph were analyzed and it was found that the appearance of 90,73,65,44 and 37 kda protein were assessed. Among which 90 kda protein is prominently seen in the haemolymph samples. An analysis of gut epithelium of the normal Bombyx mori revealed the presence of microorganisms such as Bacillus, Lactobacillus and Staphylococcus sp where as the diseased gut epithelium revealed the presence of Salmonella, Serratia and Cornybacterium. The predominant fungal isolates such as Aspergillus niger, Penicillin and Aspergillus orizae were identified in the gut epithelium of silkworm. Further molecular characterization by 16SrRNA revealed the genes of the isolates showed 780 bp DNA fragments by PCR amplification.

Helminth parasites cause a wide variety of debilitating and frequently fatal diseases in animals. Paramphistomosis caused by the paramphistome Cotylophoron cotylophorum constitutes a major group of disease in domestic ruminants. The anthelmintic activity of Syzygium aromaticum on the motility and acetylcholinesterase (AChE) activity of the digentic trematode Cotylophoron cotylophorum was studied in vitro. The flukes were exposed to various concentrations of hexane, choloroform, ethyl acetate and ethanol extract of Syzygium aromaticum and the motility and mortality of the parasite were observed. As ethanol extract was very effective, further studies were carried out with five different sub lethal concentrations (0.005,0.01,0.5, 0.1 and 0.5 mg/ml) of ethanol extract of Syzygium aromaticum (SaEE). The electronic measurement of the motility of the treated parasites clearly indicate the direct impact of the drugs on the motility of the parasite. Maximum inhibition in the motility (86.27%) and AChE activity (86.86%) was observed in 0.5 mg/ml after 8h of exposure. Acetylcholinesterase (AChE) is an enzyme which is involved in neurotransmission. It is present in the cholinergic synapses in the central nervous system as well as in neuromuscular synapses where it rapidly hydrolyzes acetylcholine. Inhibition of AChE in the parasite results in muscular paralysis and the parasite lose its biochemical hold fast and get expelled from the host.

The present study is an attempt to analyse the reproductive success in Red Wattled Lapwing (Vanellus indicus) belonging to Order Charadriiformes, by comparing two nesting sites in Jammu. The nesting sites taken under consideration were open agricultural fields and the top of flat roofed buildings. The breeding season ranged from March to August with average clutch size of 3.53 ± 0.56 eggs (n=30) and an incubation period of 28-30 days. The most preferred site for nesting was found to be agricultural fields near some water source because of availability of food. In agricultural fields due to drying up of water source during peak summer, the scarcity in food resources for the young ones was noted thereby leading to the mortality of young ones of Red Wattled Lapwing, whereas it was also observed that on roof tops, eggs or hatchlings were easily predated by predators like monitor and the young ones were not able to land safely on the ground from such a height which caused their death.

Growth rates in the mud spiny lobster, Panulirus polyphagiis held in captivity were assessed and compared with growth estimates derived from length composition of these lobsters in trawl landings at Veraval, north-west coast of India. The von Bertalanffy's growth parameters 'L∞' and 'K' derived for male P. polyphagus were 135 mm (carapace length, CL) and 0.46 y-1 in the wild and 144.8 mm (CL) and 0.51 y-1 in captivity. The values derived for female P. polyphagus were 124.7 mm (CL) and 0.38 y-1 in the wild and 119 mm (CL) and 0.43 y-1 in captivity. There was a clear difference in the growth curves of males and females in captivity and in the natural habitat. The VBGF curves indicated that males had a better growth output than females, both in the wild and in captivity. Juvenile lobsters exhibited higher moulting frequency, with the intermoult period increasing steadily as CL increased. Increments in CL at each moult showed significant correlation with increasing CL in both males and females. The rate of growth was found to decrease with age in both sexes. In males there was renewed burst of growth after the attainment of sexual maturity (65-75 mm CL) but beyond 80 mm CL, the growth was steady. In females however, there was drastic reduction in growth rates in the 63-68 mm CL range, and it steadied at 70-80 mm CL when the breeding and rematuration processes are more prominent in its life cycle.

Phenytoin is an antiepileptic drug which has been used in the present study to assess its effect on developmental toxicity from egg to adult eclosion and also life-history traits in Drosophila melanogaster. Flies were reared on media supplemented with different doses of phenytoin. The dose-dependent developmental delay, reduced pupal and adult size reduced adult eclosions, minimum larval, adult mortality, but significant pupal mortality was observed with incomplete pupal eclosion. The data show reduction in fecundity for life-history traits, but differences are not statistically significant for fertility and lifespan. The present study reveals that on exposure to phenytoin pre-adult stages are prone to developmental toxicity than the treated adult.

Regeneration is the replacement of the lost parts. Amputation was carried out through the ventral and the pelvic fin at a proximal level of Oreochromisaureus. The regeneration process has been divided into five continuous stages: wound healing, dedifferentiation stage, blastema formation stage, early and late redifferentiation and growth stages. The regenerating system was completely formed histologically by about fifteen days post-amputation. During this stage the fin grew by increasing the number of segments, rather than by increasing the length of skeletal elements. By the thirtieth day postamputation, the fin regenerate illustrated the entire histological pattern of fin regeneration. Then the growth of the regenerating fins continued by addition of new lepidotrichial segments to the end of the fin, reaching approximately the normal length and size by the forty-five day. The steady increase of glycogen content in the regenerating fins, reaching its highest level at the early redifferentiation stage met the problem of energetics, much needed during this active proliferated phase. In addition, the decrease in the glycogen content in the liver and muscles during the early phases of regeneration was indicative of the increased energy demands associated with the process of regeneration in the fish body as a whole.
