Animals with feeble locomotory power and which are carried along by the moving water are called as plankton. They are divided into phytoplankton and zooplankton. The zooplankton assemblage inhibiting freshwater mostly comprise of Protozoa, Coelenterate, Rotifera, Gastrotricha, Bryozoa and Arthropoda (Battish 1992). Most zooplankton occupies the second or third tropic level of the aquatic food web as such these herbivores, carnivores and omnivores play a significant role in aquatic food webs. The minute size of phytoplankton denotes that aquatic grazers are very small and therefore there exits many steps or links in aquatic food webs which are necessary to support large carnivores such as fish. There are many studies on the zooplankton populations of tropical ponds. As zooplankton constitutes important live feed for many economically important fishes and prawns a large quantity of zooplankton is harvested daily by the aquarists from the ponds (Altaff et al 2002). ····· 1036120145

Glutamate is a major neurotransmitter that acts on extensive brain regions, such as hypothalamus and the pituitary and induce the secretion of PRL. In this study, young male rabbits (Lates calcarifer) of 3 to 4 months of age were treated with 2mg/g body weight MSG dissolved in 0.9% saline. The animals in control group received equal quantity of 0.9% saline. Blood samples were collected 15 minutes after administration of drug, and plasma was separated. All plasma samples were analyzed by Enzyme linked Immunosorbent Assay (ELISA). Within the control group, there was no significant difference in plasma PRL level (p0.05). In treated group, plasma PRL level was highest in T2 (2.69 ± 0.042 ng/ml) and lowest in T1 (2.16 ± 0.067 ng/ml). Administration of glutamate in the form of MSG causes tonic activation of tuberinfudibular dopaminergic neuron system (TIDA). As a result dopamine release, PRL level in prepubertal rabbits decreases. Regression analysis of variance showed non significant negative trend in plasma PRL level (p 0.05) in animals of control and treated group. ····· 1036119983

A microorganism may live passively within the external environment, yet share a close and apparently mutualistic association with an insect. Alternatively, the relationship may be so mutualistic that a microorganism is obligately restricted to living within specialized insect tissues. Microorganisms are known affect almost every aspect of insect physiology and are a necessary component underlying many insect behaviours. Over the last 100 years, the number of known, beneficial microorganisms has grown steadily. This guide compiles those known examples, describes the method in which each microorganism is transmitted among insects, and indicates how the microorganisms are experimentally manipulated to ascertain their beneficial function. ····· 1036119587

Cortisol is essential for provision of nutrients to tissues via carbohydrate, protein, and lipid metabolism. It also affects all of the major systems of the body, including the cardiovascular, musculoskeletal, nervous, and immune systems, and play critical roles in fetal development. Secretion of cortisol is controlled by hypothalamus, pituitary and the adrenal gland. CRH released from the hypothalamus acts on pituitary gland to release ACTH, which acts on the adrenal gland to increase the synthesis and release of cortisol. This book focuses on the changes in plasma cortisol observed in adult male rabbits treated with monosodium glutamate. Monosodium glutamate, is the salt which is frequently used in daily life. This book demonstrates that how monosodium glutamate crosses the blood brain barrier acts on the HPA axis and consequently increases the plasma cortisol level. ····· 1036119450
für 44.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray Over the last decade or so, the use of insecticides has increased exponentially, and some of these are carcinogenic and therefore, banned from usage completely. With the advent of biopesticides and integrated pest management (IPM), the focus is on ecofriendly approaches and very little academic literature exits on how to best utilize this arena for acridiods of agricultural importance. Insect pests have been estimated to cause $90.5 billion dollars in damages to eight principal food and cash crops viz., rice, wheat, barley, maize, potato, soybean, cotton and coffee versus $76.9 billion dollars damage by disease pathogens and $76.3 billion dollars by weeds. It has been suggested that by adopting insect pest management, the global crops could be doubled. This book, therefore, should help shed some light on crop damage by grasshoppers and the results of such studies will be instrumental in understanding and devising population management strategies and should especially be useful to farmers, entomologists, agriculturists, or any one else who may be considering to take a lead role in crop production. ····· 1036119333

Poor excreta disposal is often associated with lack of adequate water supplies, poor sanitation facilities and low economic status populations. In this study water samples were collected from wells, taps and harvested rain water containers in Kimumu area of Eldoret municipality in Kenya and analyzed using standard bacteriological and parasitological methods. The quality of tap and rain water was found to be acceptable. The presence of Escherichia coli in well water was an obvious indication of faecal contamination. Faecal parasites observed were Entamoeba histolytica, Ascaris lumbricoides, Giardia lamblia, Necator americanus, Ancyclostoma duodenale, Fasiola hepatica, Taenia saginata and Taenia solium. To control infestations with faecal intestinal parasites, provision of treated piped water to all homesteads, consultation of water engineers and/or health inspectors before well construction and creation of public awareness are recommended.

The taxonomic part comprises of identification of the available specimens up to species level. It provides information on nematode association of these cash crops which is important globally. The ecological part includes the monthly population fluctuation. As the different edaphic factors, like soil moisture, temperature, pH, nitrogen, phosphorus, potassium, organic carbon & soil electrical conductivity are the determining factors for the shape and quality of the nematode population in soil micro-environment, the effects of these soil factors on nematode population have been investigated. The effectiveness of predatory and omnivorous nematodes as a bio-controlling agent to reduce the population of tylenchids was tested statistically.

The Present work aims at the determination of total lipid in livers of commercially important major carp. Total lipid profile in female C. catla was measured to study variations from immature to mature stage. Variance between hepatosomatic index (HSI) and gonadosomatic (GSI) index and total body weight with respect to total lipid in liver is also studied. These variations were studied in relation with environmental parameters. Seasonal variations in the level of lipid in fish are related maily to the reproductive cycle. They accumulate large lipid reserves prior to gonadal development. In general fatty acids are mobilized from the lipid reserves of fish during gonadogenesis and transferred via the serum to liver where they are assembled into the lipoprotein, vitellogenin. The total lipid (phospholipids, cholesterol and triglyceride) can be catabolized to provide metabolic energy for egg lipoprotein synthesis. ····· 1036118488
