Structure and Function of The Digestive System of Vertebrates
ISBN: 9783844331196 / Angielski / Miękka / 72 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Over the last few years, the use of histological, histochemical and ultrastructural studies with scanning and transmission electron microscope become a good tools in Comparative Anatomy studies of some parts of the digestive system of different vertebrates.Three separate parts; buccal cavity, intestine and liver of fish and the tongue of birds were investigated. The investigation should help shed some light on these parts relating the structure to the function.These studies should be especially useful to comparative anatomists, histologists, pathologists, ornithologists and marine biologists.

Wildlife Conservation in Nigeria's National Parks
ISBN: 9783844315264 / Angielski / Miękka / 200 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. This book examined the performance of uniform wildlife laws in four selected National Parks in Nigeria between 1991 and 2004. The study became necessary because some authors have argued that the rapid loss of wildlife species in protected areas are largely attributable to the gross deficiencies inherent in the wildlife laws applied without considerations of the peculiar characteristics of the host communities and ecological differences in the respective protected areas. The study, therefore, appraised the occurrence of various wildlife offences in relation to convict sentences ...

A study on Himalayan Brown Bear in India
ISBN: 9783845413174 / Angielski / Miękka / 104 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Among the four species of bear in India, the Himalayan brown bear (Ursus arctos) is least distributed and occurs in very low densities in the alpine region of the Greater and Trans Himalayan zones in India. It is rare and usually encountered between 2800m to 4800m elevation. Population of brown bear is largely confined to the western and northwestern Himalayan regions in India and distributed mainly in the states of Jammu and Kashmir, Himachal Pradesh, Uttaranchal and Sikkim. Schaller (1969) stated that the Himalayan brown bear is largely confined to rolling uplands and high forests of...

To beat or not to beat?
ISBN: 9783838315010 / Angielski / Miękka / 204 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. All social relationships rely upon an organism's ability to remember conspecifics. The ability to recognize individual conspecifics is crucial in many aspects of an animal's social behavior and this type of memory is critical for the stability of relationships and survival. Individual recognition requires the association of individually distinct information with memories of past experiences. Such recognition may be a specially evolved type of learning and memory and in many species olfaction is important for such recognition. To further understand this complex cognitive function, we developed...

Integrated Control of Insect Pests in Commercial Mushroom Production
ISBN: 9783838338217 / Angielski / Miękka / 252 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. The control of sciarids and phorids, two major pests of the cultivated mushroom was studied to provide elements of an integrated pest management strategy in a commercial environment. Use of light- trapping to control sciarids and phorids within mushroom production houses was examined. Both sciarids and phorids were attracted to relatively low light emissions from sources of differing wavelengths. Predatory mites and entomopathogenic nematodes controlled sciarids and phorids in compost and casing substrates. In studies combining biological and chemical control, application of entomopathogenic...

On the Brain of Cartilaginous Fishes
ISBN: 9783838316109 / Angielski / Miękka / 128 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. This book discusses the correlation between the cerebralization, the astroglial architecture and the blood-brain barrier composition in cartilaginous fishes. Chondrichthyes display a wide range of cerebralization, with the highest brain weight/body weight ratio represented by galeomorph sharks and batoids of the myliobatiform order. The examination was extended to representatives of all these important groups and the book presents the first study on the glial architecture of a Holocephali as well. The present work supplements the former glial impregnation studies; three different...

Effect of Nicotine on Haematology and Reproductive Hormones in Mice
ISBN: 9783847305545 / Angielski / Miękka / 112 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Nicotine is one of the main and toxic alkaloid in tobacoo which is largely absorbed in the body through cigarette smoking. A considerable amount of nicotine is found to be present in blood of tobacoo smokers and snuffers and is largely responsible for various physiological changes. Smokers are at a greater risk of various vascular diseases due to change in their hematological variables. It has been shown that administration of nicotine to healthy mice results in increase in white blood cell (WBC) and platelets (PLT) counts. High count of PLT may lead to thrombosis and other cardiovascular...

Toxic effects of hexane extract of O. limbata on D. melanogaster
ISBN: 9783847308720 / Angielski / Miękka / 72 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Insect damage in stored food grains may amount to 10%-40% in countries where modern storage technologies have not been introduced. The loss of the olive crop due to the damage inflicted mainly by Dacus oleae (Insecta, diptera), range from 10 to 70%. According to FAO the loss annually by insects and rodent pests is 10 to 25% of world harvested food. In Pakistan, fruit flies cause a loss of around Rs.7 million annually. While according to another report, in Pakistan about 2 - 6% food grain production is lost every year during storage by stored grain insect pests. Similarly the total post...

Cadmium Toxicity-Impact on reproductivity
ISBN: 9783847306092 / Angielski / Miękka / 96 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Cadmium is toxic to a wide range of organisms; the main effects are on the growth and reproduction. Dissolved cadmium salts released in drainage water from mines may represent a significant threat to aquatic wildlife. Reproductively active aquatic animals exposed to pollutant stress undergo alterations in their biochemical and physiological functions leading to the disturbed reproductive processes. Biochemical constituents and enzymes are the first detectable / quantifiable responses to environmental changes and can serve as markers for both exposures and effects in organisms. In the edible...

Dynamics of Small Neural Populations
ISBN: 9780821804582 / Angielski / Twarda Termin realizacji zamówienia: ok. 5-8 dni roboczych. This work arose from a series of lectures presented at the CRM Summer School in Mathematical Biology held at the University of British Columbia in the summer of 1993 by John Milton, a clinical neurologist and biomathematician. In the work, three themes are explored: time-delayed feedback control, noise, and statistical properties of neurons and large neural populations. This volume focuses on systems composed of 2-3 neurons. Such neural populations are small enough to permit experimental manipulation while at the same time being well enough characterized so that plausible mathematical models...
