Marine mammal ecology and conservation : a handbook of techniques by I. L Boyd( )

9 editions published between 2010 and 2011 in English and held by 1,458 WorldCat member libraries worldwide

"Marine mammals command a high level of public attention, reflected in specific legislation for their protection and management in many countries. They also present particular challenges to ecologists and conservation biologists: they are mostly difficult to observe, they occupy an environment that is vast in its three dimensional extent, there are often perceived conflicts between marine mammals and people, and furthermore several species are now close to extinction. Marine mammals have some intriguing features in their biology--the ability to dive to crushing depths, to perform breath-hold dives that defy our current understanding of mammalian physiology, and many have an ability to hunt down prey using sophisticated sonar that we are only just beginning to understand. Many species also have complex social structures. We still have much to learn about these extraordinary animals so a comprehensive and authoritative overview of current methodology is now timely. The intention of this book is both to summarize the state-of-the-art and to encourage innovation and further progress in this research field. Written by leading practitioners in the field, this accessible text is suitable for graduate students and professionals in the fields of marine mammal biology, conservation biology, and ecology, as well as nature conservation practitioners and marine mammal specialists"--Jacket
Top predators in marine ecosystems : their role in monitoring and management by C. J Camphuysen( )

15 editions published in 2006 in English and held by 951 WorldCat member libraries worldwide

Seals, seabirds, whales and dolphins are at the top of marine food chains: studying their ecology can help identify and monitor changes in wider marine ecosystems. This book examines our current understanding of marine predator ecology and investigates how it can be used in management and conservation of marine habitats

The use of data loggers to determine the energetics and physiology of aquatic birds and mammals by P. J Butler( )

2 editions published in 1995 in English and held by 3 WorldCat member libraries worldwide

By deploying a data logger specifically designed for the purpose, it was possible to record heart rate, fH (beats/min), from free-ranging gentoo penguins, Pygoscelis papua, Antarctic fur seals, Arctocephalus gazella, at the British Antarctic Survey Base at Bird Island. The heart rate data were then converted into oxygen consumption (VO2, ml O2 min( -1) kg( -1)) and/or energy expenditure (W/kg) using equations that had been derived from calibration experiments. In these experiments the relationships between fH and VO2 were determined in animals at rest and while exercising at different levels on a treadmill or in a static water channel (penguins) and in a variable speed flume (California sea lions, Zalophus califonianus, as surrogate fur seals) or in a static water channel (fur seals). The validity of using these relationships was tested by recording simultaneously fH, VO2 by direct respirometry and VCO2 by the doubly labelled water (DLW) technique in six penguins and in six California sea lions during 72 h and 24 h, respectively, at various levels of activity. For the penguins, both indirect methods gave mean algebraic errors within 2 percent of the measured VO2, whereas for the sea lions, the mean algebraic errors were 36.4 percent for the DLW method and 2.7 percent for the fm method. The range of errors was greater for the DLW method, in both species. Field data from 15 penguins indicate that the fH method provides data that are comparable to those obtained using the DLW method, but with the added advantage that they can be broken down into the energy costs for specific types of behaviour. The implanted data loggers also recorded the temperature of the abdominal cavity (Tab) and it was evident that this routinely decreased by approximately 2 degrees Celsius during diving bouts and by a maximum of almost 5 degrees Celsius. Such temperature decreases, particularly if representative of similar decreases in other tissues, may at least partly explain why the energy costs of travelling to and from the foraging site and of foraging itself are similar to those for penguins resting in water at 5 degrees Celsius. Field data from 15 female fur seals indicate that, when the animals are ashore, there is good agreement between the values for mean energy expenditure obtained by the fH and DLW methods. However, when the animals are at sea, the values obtained by DLW are substantially greater than those obtained by fH. When the at-sea values are corrected for the apparent overestimations referred to above, there is good agreement between the data obtained using the two methods. The data derived from fH indicate that, as with the penguins, the energy expenditures during travelling to and from the foraging site and during foraging are similar to those of fur seals resting in water at 70 degrees Celsius.(AU)
