Ecology of the Forest Owlet
ISBN: 9783844305722 / Angielski / Miękka / 204 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. The Forest Owlet is a critically endangered bird species rediscovered after 113 years in November 1997 in Satpuda Mountains of Central India. The Forest Owlet utilizes open forests with moderate undergrowth and least anthropogenic disturbance. It preys upon rodents, skink, agamid and insects and shows seasonal variation in diet. It shows nest site fidelity during breeding season which plays a vital role in breeding success. Predation of fledglings, ovicide, infanticide and egg stealing from nest by humans are the major factors influencing the breeding success of the Forest Owlet....

Neuroendocrine Network and Immuneregulation
ISBN: 9783844317626 / Angielski / Miękka / 136 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Immunity, a primeval feature of living organisms & is essential for reproduction and to face the challenges originating from seasonal variation and environmental threats as well. Present study reveals that how tropical animals have evolved a mechanism via melatonin to blaster the immune function to counteract seasonally recurrent stressors that may otherwise compromise immune functions. Finding suggests that melatonin is having an adaptive significance in balancing immune status in this rodent. It acts during winter as immuno-stimulator to save the squirrels from the adverse condition...

Sex and sociality in fishes
ISBN: 9783844314304 / Angielski / Miękka / 196 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. One of the fundamental goals of behavioural ecology is to understand the evolution of animal societies - how they are formed, structured and stabilized. A generalised understanding of the functioning of animal societies has clear, far-reaching consequences for our understanding of the evolutionary origins of our own societies. In order to shed light on our own behavioural characteristics, we much first conduct detailed investigations into the structure, functioning and stability of model animal systems that can be experimentally manipulated to test key theories in social...

Keys to the Cestode Parasite of Vertebrates
ISBN: 9780851988795 / Angielski / Twarda / 768 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Most previous publications on the classification of tapeworms (cestodes) have been based on compilations from the literature and are now dated. Thus there is a real need for up-to-date keys based on the re-examination of specimens and on a re-evaluation of the characters employed in cestode taxonomy. This book fulfils this need and provides keys to enable specialists and non-specialists to identify cestodes to generic level. The keys are dichotomous and are based largely on morphological characters.

The Gas Exchangers: Structure, Function, and Evolution of the Respiratory Processes
ISBN: 9783540625117 / Angielski / Miękka / 498 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. The factors which set the metabolic potentials of animals - the physicochemistry of the respiratory medium utilized, the phylogenetic level of development, the habitat occupied, and the life-style pursued -, have been the most decisive determinants of the constructions of the gas exchangers. After molding the most appropriate respiratory devices and adjusting them in accord with the individual needs for molecular oxygen, animals occupy different ecological niches and even share common environments. From the perspective of respiration, they have very few choices: there are only two fluid...

Genetic Susceptibility to Coxsackievirus B3 Myocarditis
ISBN: 9783844300260 / Angielski / Miękka / 208 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Coxsackievirus B3 (CVB3) is the second main causes of viral myocarditis. Mouse infection with CVB3 mimics the heterotypic response to virus-induced disease observed in humans. Here we have used Evans blue dye as a quantitative biomarker for susceptibility to CVB3-induced myocarditis in addition to histopathological semi quantitative measures. We have found evidence of linkage between susceptibility to viral myocarditis and three loci. A locus on chromosome 1 was linked to sarcolemmal disruption in males (P=0.00005), a second locus on chromosome 4 was also linked to...
