The Cnidaria
Cnidarians are elegant and dazzling aquatic organisms, but despite their beauty they are known to be a threat in many coastal areas around the world. Several species of cnidaria living in tropical or sub-tropical areas are remarkably dangerous, but many Mediterranean species can also cause serious health problems. Really, cnidarians (sea anemones, corals, medusae) are considered among the most dangerous and venomous organisms, thanks to the occurrence in their tissues of batteries of intracellular capsules (nematocysts or cnidocysts) produced by the Golgi apparatus of specialized cells (nematocytes or cnidocytes) from which the phylum Cnidaria takes the name (from the Greek κνίδη = nett...

Alternative Tourism in Turkey
This book takes inventory of and evaluates the available resources for the development of alternative tourism in Turkey. It examines the role of alternative tourism in future tourism development plans and proposes public policies necessary to assure sustainability. Although tourism started later in Turkey than in the Western Mediterranean countries it has grown very rapidly during the last three decades and today the country ranks among the top ten countries in the world in terms of both arrivals and receipts. However, most of the tourism development has been in the mass tourism sector or the so-called sun-sea-sand tourism. While crucial for the economic development of Turkey, mass tourism, in the absence of proper planning, has happened in a haphazard manner leading to numerous environmental and socio-cultural problems. This book argues that, in order to mitigate these problems, Turkey should encourage the development of alternative forms of tourism.
Odd Couples
The remarkable and unique ways that male and female animals play out gender roles in nature While we joke that men are from Mars and women are from Venus, our gender differences can't compare to those of many other animals. For instance, the male garden spider spontaneously dies after mating with a female more than fifty times his size. And male blanket octopuses employ a copulatory arm longer than their own bodies to mate with females that outweigh them by four orders of magnitude. Why do these gender gulfs exist? Introducing readers to important discoveries in animal behavior and evolution, Odd Couples explores some of the most extraordinary sexual differences in the animal world. Daphne Fairbairn uncovers the unique and bizarre characteristics of these remarkable species and the special strategies they use to maximize reproductive success. Fairbairn also considers humans and explains that although we are keenly aware of our own sexual differences, they are unexceptional within the vast animal world. Looking at some of the most amazing creatures on the planet, Odd Couples sheds astonishing light on what it means to be male or female in the animal kingdom.
Marine Ecological Processes
This text is aimed principally at the beginning graduate or advanced undergraduate student, but was written also to serve as a review and, more ambitiously, as a synthesis of the field. To achieve these purposes, several objectives were imposed on the writing. The first was, since ecol ogists must be the master borrowers of biology, to give the flavor of the eclectic nature of the field by providing coverage of many of the interdis ciplinary topics relevant to marine ecology. The second objective was to portray marine ecology as a discipline in the course of discovery, one in which there are very few settled issues. In many instances it is only possible to discuss diverse views and point out...
Arterial Chemoreception
Arterial chemoreceptors are unique structures which continuously monitor changes in arterial blood oxygen, carbon dioxide, glucose, and acid. Alterations in these gases are almost instantaneously sensed by arterial chemoreceptors and relayed into a physiological response which restores blood homeostasis. Arterial Chemoreception contains updated material regarding the physiology of the primary arterial chemoreceptor; the carotid body. Moreover, this book also explores tantalizing evidence regarding the contribution of the aortic bodies, chromaffin cells, lung neuroepithelial bodies, and brainstem areas involved in monitoring changes in blood gases. Furthermore this collection includes data showing the critical importance of these chemoreceptors in the pathophysiology of human disease and possible therapeutic treatments. This book is a required text for any researcher in the field of arterial chemoreception for years to come. It is also a critical text for physicians searching for bench-to-bedside treatments for heart failure, sleep apnea, and pulmonary hypertension.
The Unexpected Truth about Animals
Whether we're watching a viral video of romping baby pandas or looking at a picture of penguins `holding hands', we often project our own values; innocence, abstinence, hard work - onto animals. So you've probably never considered that moose get drunk and that penguins are notorious cheats. In The Unexpected Truth About Animals Zoologist Lucy unravels the many myths we humans like to believe!
