Animal Acoustic Communication: Sound Analysis and Research Methods
ISBN: 9783642762222 / Angielski / Miękka / 421 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. The last decades have brought a significant increase in research on acoustic communi cation in animals. Publication of scientific papers on both empirical and theoretical aspects of this topic has greatly increased, and a new journal, Bioacoustics, is entirely devoted to such articles. Coupled with this proliferation of work is a recognition that many of the current issues are best approached with an interdisciplinary perspective, requiring technical and theoretical contributions from a number of areas of inquiry that have traditionally been separated. With the notable exception of a...

Invertebrates in Hot and Cold Arid Environments
ISBN: 9783642795855 / Angielski / Miękka / 275 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Comparisons are made of the adaptations of invertebrates from polar deserts with those of temperate and subtropical deserts. These regions represent some of the most hostile environments on earth and an array of strategies for survival has been developed. Polar species are well adapted to cold and experience arid conditions due to low precipitation and lack of liquid water during the winter. Similarly, temperate desert invertebrates are adapted to dry conditions and are also exposed to low winter temperatures.
Terrestrial arthropods maintain their water balance through behavioural and... Comparisons are made of the adaptations of invertebrates from polar deserts with those of temperate and subtropical deserts. These regions represent s...

Multicellular Animals: A New Approach to the Phylogenetic Order in Nature Volume 1
ISBN: 9783642801167 / Angielski / Miękka / 225 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. No one can ever have secure knowledge about the gods and creatures, and should anyone hit by chance upon the right thing, he will not know it for sure; that is why everything that we believe to be true is "opinion." XENOPHANES around 500 B.C. (According to ROD 1988, p.85) The goal of phylogenetic systematics (cladistics) is to discover the kinship relations between all organisms on earth and to translate the order we perceive in Nature into an equivalent man-made system. Although the goal is easily formulated, the path is thorny, and the results achieved continue to be imperfect. This is the...

Chemical Recognition in Biology
ISBN: 9783642815058 / Angielski / Miękka / 430 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Studies of chemical recognition in biology were initiated about half a century ago with the flrst kinetic data obtained on enzyme catalysis and inhibition. They led to a rather static representation of the recognition process illustrated by the lock and key model that still continues to influence our overall image of recognition and its specificity. In several cases, crystallographic studies of enzyme-substrate complexes have supported this model. Indeed, in a crystallized ligand-enzyme complex, a close fltting is observed between the active center of the enzyme and the functional groups of...

Osmoregulation in Birds
ISBN: 9783642815874 / Angielski / Miękka / 205 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. The approach of this treatise is physiological throughout. In the eyes of the author it answers the rhetorical question raised by Maurice B. Visscher at the Physiology Congress in Washington D. C. in 1968: Does physiology exist? What he meant by this question was whether the fields of cellular physiology and physiology of the various organ systems had become so large that physiology as such had vanished. The firm answer is that physiology does indeed exist. Although it is important to study physiological problems at the subcellular level, it is importan- and equally difficult - to study organ...

An invitation from the Editors to contribute to 'Studies of Brain Functions' with a monograph on the parietal lobe of fers me an opportunity to present in a concentrated form my studies on this part of the brain from a period of some what over a decade. The parietal lobe, notably its posterior part, is a very complex neural system whose functions I have been able to study only superficially and without ex tensive coverage of all its parts. Therefore I did not want to limit myself entirely to my own work but found the task of writing more interesti'ng by including sections reviewing rel evant...

Olfactory Imprinting and Homing in Salmon: Investigations Into the Mechanism of the Imprinting Process
ISBN: 9783642820724 / Angielski / Miękka / 138 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Chance Favors Only the Prepared Mind How does a scientist go about the task of pushing back the curtains of the unknown? Certainly the romance of tackling the mysteries of nature provides the motivation, for who would not be inspired by the remarkable life history of this romantic beast, the salmon. After living in the Pacific Ocean for several years, salmon swim thousands of kilometers back to the stream of their birth to spawn. I have always been fascinated by the homing migration of salmon. Noone who has seen a 20-kilogram salmon fling itself into the air repeatedly until it is exhausted...

The Control of Fish Migration
ISBN: 9783642823503 / Angielski / Miękka / 246 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Fish migration is important and spectacular. Migratory fish gather energy in one portion of the environment and transport it to other areas, where it often becomes available to humans or to other elements in the ecosystem. Migration brings fish into situations that allow easy harvest as they concentrate along migration routes. Their journeys also make them vulnerable to human intereference at critical points along their route. Salmon, for example, may harvest plankton in the open ocean and transport that food energy to coastal and inland regions, where it is captured by fisheries or deposited...

Comparative Aspects of Extracellular Acid-Base Balance
ISBN: 9783642831324 / Angielski / Miękka / 248 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Interest in comparative acid-base physiology has considerably grown during last decades even in the absence of major technical or conceptual advances. This is firstly because it has become clear that the extracellular acid-base state reflects the performance of many exchange functions at the organism level: respiration and ventilation of the gas exchange surfaces, metab olism, iono-and osmoregulation. Such functions are much in fluenced by ambient conditions, and the measurement of acid base parameters thus provides useful information about the organism's responses to environmental...

Vertebrate Flight: Mechanics, Physiology, Morphology, Ecology and Evolution
ISBN: 9783642838507 / Angielski / Miękka / 291 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. It has been great fun to write this book, even though it has taken longer than planned, and occasionally been exasperating. The most difficult problem was deciding what to exclude among so many interesting things, because the available material usually exceeded the space. Because a book like this covers so many aspects, each component must be limited. This book is intended for graduate and undergraduate students as well as professional scientists who want to work with animal flight or to gain some insight into flight mechanics, aerodynamics, energetics, physiology, morpho logy, ecology and...

Las tortugas marinas representan a los organismos mas primitivos e iniciaron su evolucion en el periodo Triasico, a principios del Mesozoico, hace por lo menos 200 millones de anos. Fueron muy abundantes en el pasado pero en el ultimo siglo sus poblaciones se han visto reducidas drasticamente (Marquez, 2002) Entre los principales factores que afectan negativamente las poblaciones estan los depredadores naturales, los abusos y la sobreexplotacion del hombre, los cambios en sus habitats, las enfermedades infecciosas y parasitosis. A pesar de su importancia como especie ancestral en peligro de...
