Aquatic Vertebrates of Haleji and Keenjhar Lakes
ISBN: 9783847332336 / Angielski / Miękka / 224 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. In the present study, the effects of environmental pollution on aquatic vertebrates of two Ramsar Sites viz. Haleji and Keenjhar Lakes were noted and inventories of the vertebrate fauna were prepared. In the water samples taken from Haleji Lake, the pesticides of organophosphate (OP) and organochlorine (OC) groups were estimated above the Maximum Acceptable Concentrations (MAC). These concentrations were much higher in muscles and fat contents than other tissues of birds. All water samples from Keenjhar Lake contained pesticides below the MAC level. A total of 22 species of mammals, 228...

Development of a bait for the longlining fishery of snapper
ISBN: 9783838360812 / Angielski / Miękka / 68 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Natural baits such as squid and pilchard have been the favored choice of fishermen for the longline fishing of snapper (Pagrus auratus) in New Zealand. Overexploitation of fish stocks together with an increase in demand for fish for human consumption has decreased the resources of natural baits at cost effective prices. This has lead to attempts in the development of artificial or reconstituted baits. In this study, baits were prepared using differing proportions of industry surplus Greenshell Mussel and gurnard which are know to be part of the snapper diet. These species also contain large...

Dynamics of Salticid-Ant Mimicry Systems
ISBN: 9783838359915 / Angielski / Miękka / 76 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. The world of mimicry is vast and varied. This becomes apparent when we consider mimicry in arthropods, the largest group of animals on the planet. The strategies adopted by different mimics to improve their chances of survival by gaining protection from predators, or by becoming more successful predators themselves, are reflected in extraordinary morphological, chemical and/or behavioural modifications. These adaptations due to natural selection are worthy of being studied within the fields of evolutionary biology to further our knowledge. This book presents a study of behaviour in two genera...

Aquatic Pollution
ISBN: 9783838394107 / Angielski / Miękka / 96 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. There is a clarion call to protect the environment from pollutants and toxins. Besides habitat loss and over exploitation, pollution is ranked as the main cause of fish species loss and the use of pesticides is one of the main causes of aquatic pollution. A lot of factors like increased agricultural activity and industrialization due to the increase population jointly contribute to the loading of the environment with residues of potentially hazardous pesticides and other toxic pollutants. Diazinon is a common active component of organophosphorus pesticide which is widely used as an...

Study of Effects of Pesticides on Common Carp Spawn
ISBN: 9783843358538 / Angielski / Miękka / 60 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Although, pesticides are very useful for saving human life from many diseases and protecting food and other economically important food crops from pest damage, some pesticides are not readily biodegradable, tend to persist for a long period in the environment and move to other parts of the environment. The detrimental effects of these chemicals can be seen on organisms other than the target pests. These toxic substances exist in a variety of chemical and biological forms including organochlorines, organophosphates, carbonates, etc. Pollution of aquatic systems due to these...

The environmental light to which most animals are exposed has a major influence in their physiology. Over the decades attempts are being made to understand the physiological mechanism of the processing of environmental light information in the regulation of various body functions in general and reproduction in particular. Light as a source of environmental cue in the use of regulation of reproduction has also been considered for fish, the study on which has gained momentum because of its tremendous economic importance as food. Thus for obvious reasons efforts are continued to develop...

Hypoxia on rat brain and therapeutic use of superoxide dismutase
ISBN: 9783845414416 / Angielski / Miękka / 164 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. This book deals with the study on the effect of isobaric hypoxic hypoxia (10%) on rat brain. Since literatures support generation of free radicals during post ischemic/hypoxic period, here hypoxia followed by reoxygenation is dealt with as the single problem. Subsequently, as brain shows regional variations in its function and metabolic activities an attempt was made to study effect of hypoxia- reoxygenation in five brain regions ie cerebrum, cerebellum, medulla, hippocampus and hypothalamus. The changes in the activities of antioxidant defense enzymes (superoxide dismutase, catalase and...
