Tissue damage in the liver and intestine of viper snake by nematodes and in the intestine of cobra by an acanthocephala is described here. These snakes were naturally infected with the parasites. Study of tissue sections revealed that the nematodes in the liver of viper cause severe damage including destruction of general architecture, atrophy and fibrosis. Lobular configuration of liver was disturbed, coagulated necrosis has occurred, melanomacrophage centers appeared. Bile duct hyperplasia with marked colangiohepatitis was observed. In the intestine the nematode caused fusion and...

Behavioural ecologists and evolutionary biologists have long recognised Professor Tinbergen's great prescience in placing the study of animal behaviour firmly in an ecological and evolutionary context nearly fifty years ago. This is a reprint of the 1969 edition of The Study of Instinct (originally published in 1951). The first six chapters cover behaviour as a response to stimuli, the neurophysiological bases of innate behaviour as then understood, and the development of behavioural patterns in individuals. The final two chapters are devoted to the adaptativeness of behaviour and...

protein and amino acid responses of broilers with low-energy diets
ISBN: 9783639236316 / Angielski / Miękka / 144 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Energy is often considered as the start-point for least-cost diet formulation for poultry. Broilers have remarkable tendency to achieve certain gains for age, through modifying voluntary feed intake when offered an array of dietary energy. In this context, the decision regarding the optimum dietary level of energy seems merely a function of the unit cost of energy and the premium achieved in terms of improved feed efficiency. This implies that, depending upon the availability and price of feedstuffs, there could have been situations where low-energy diets could prove economically...

Aluminum had obviously permanent retardation in the functions of the nervous system paralleled with retarded neurologic development leading to disturbed learning ability and exploration deficiency in neuro-muscular coordination, with an uncontrollable emotionality and excitability, concomitant with increased aggressive behaviour. These effects were the results of perturbations in the brain activities of AChE and ATPase activities concomitant with agitated levels of several amino acids and monoamine neurotransmitters. Vitamin E curtailed some of the aluminium- induced physiological and...

Impact of Insect Pollinators on Sesame Production
ISBN: 9783659442902 / Angielski / Miękka / 92 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. In Egypt, sesame is considering a food crop rather than oilseed crops because most of its seeds consumed directly. It is grown in many Governorates, and ranks first among the cultivated oil crops in Ismailia Gov. Co-evolution of flowering plants and their pollinators started about 225 million years ago. Insufficient number of suitable pollinators causes decline in fruit and seed production. Of the total pollination activities, over 80% is performed by insects and bees contribute nearly 80% of the total insect pollination, and therefore, they are considered the best pollinators. Sesames...
