The measurement of metabolic rates is central to important questions in many areas of physiological research. Unfortunately these measurements are anything but straightforward, with numerous pitfalls awaiting both the novice and even the experienced investigator. The original edition of this work, published in 2008, quickly became the principle "how to" manual for the field. It successfully de-mystified the topic, explaining every common variation of metabolic rate measurement. Background information on different analyzer and equipment types allowed users to choose the best instruments for their application. Respirometry equations, normally a topic of terror and confusion to researchers, were derived and described in sufficient detail to facilitate their selection and use. In this new edition, the content has been thoroughly updated and a decade of new literature incorporated. New chapters on room calorimetry, human metabolic measurement, and metabolic phenotyping have also been added.

The book begins by describing in detail the mechanisms of energy exchange – radiative, convective, conductive and evaporative – together with techniques for their determination. The discussion extends to the importance of CO2, ozone and methane, together with that of aerosol pollutants and the evolution of atmospheric CO2. Subsequent chapters apply the results of the biophysical methods to mammals, birds and aquatic animals. Discussion includes problems of shelter and shade for animals in tropical environments and techniques for the thermal evaluation for shelters and for several tree types. The details of heat exchange between animals and the environment are presented, in separate chapters covering Mammals and Birds and Aquatic Mammals. A chapter on Shade and Shelter describes the importance of shade for animals, factors of shade efficiency, the protections offered by shelter and methods of calculating the protection afforded by both shade and shelter. A Special Methods chapter offers a variety of techniques for evaluating cutaneous and respiratory evaporation, and practical methods for sampling of hairs and the evaluation of hair coat characteristics.

One of the first textbooks in this emerging important field of ecology. Most of ecology is about metabolism: the ways that organisms use energy and materials. The energy requirements of individuals – their metabolic rates – vary predictably with their body size and temperature. Ecological interactions are exchanges of energy and materials between organisms and their environments. So metabolic rate affects ecological processes at all levels: individuals, populations, communities and ecosystems. Each chapter focuses on a different process, level of organization, or kind of organism. It lays a conceptual foundation and presents empirical examples. Together, the chapters provide an integrated framework that holds the promise for a unified theory of ecology. The book is intended to be accessible to upper-level undergraduate, and graduate students, but also of interest to senior scientists. Its easy-to-read chapters and clear illustrations can be used in lecture and seminar courses. Together they make for an authoritative treatment that will inspire future generations to study metabolic ecology.

Energy metabolism is central to life and altered energy expenditure (EE) is often cited as a central mechanism responsible for development of the obese phenotype. Resting EE, EE of physical activity, cold induced thermogenesis and thermic effect of feeding add to produce total EE but can also affect each other. It is thus very important that each component be well measured. Measuring energy expenditure by indirect calorimetry is extremely simple in theory but the practice if far more difficult. Taking into account temperature in small sized animals, measuring accurately the effect of activity on EE, correcting EE for body size body composition, age sex etc… add difficulties in producing reliable data. The goal of this Research Topic was to call for the practical experience of main investigators trained to practice calorimetry in order to get their feedback and the way they deal with the various and specific problems of humans and animal calorimetry. The goal is to share the questions/solutions experienced by the contributors to inititate a “guide of the good practices” that can be periodically updated and used by all those who are and will be interested in measuring energy metabolism from the 20g mouse to the human and large farm animals.

Science students are expected to produce lab reports, but are rarely adequately instructed on how to write them. Aimed at undergraduate students, Successful Lab Reports bridges the gap between the many books about writing term papers and the advanced books about writing papers for publication in scientific journals, neither of which gives much information on writing science lab reports. The first part guides students through the structure as they write a first draft. The second part shows how to revise the report and polish science writing skills as the student continues to write science lab reports.

Fressen, nicht-gefressen-Werden, Paarungspartner finden und Junge erfolgreich aufziehen Peter Kappeler erläutert, ausgehend von den vier "Grundproblemen", die jedes Tier lösen muss, die Verhaltensbiologie als integrative Disziplin der organismischen Biologie. Er berücksichtigt dabei - die evolutionäre Bedeutung diverser Anpassungen des Verhaltens, - die Ausprägung von Verhaltensweisen durch ökologische Rahmenbedingungen, life history-Strategien sowie bauplanspezifische, anatomische und physiologische Zwänge und Möglichkeiten, - moderne Konzepte und Erkenntnisse der Verhaltensökologie, Soziobiologie und Evolutionsbiologie. Der didaktische Schwerpunkt liegt auf einer klaren Darstellung und Übersicht der grundlegenden Prinzipien und Probleme. Klassische und vor allem aktuelle Beispiele, besonders aus dem deutschsprachigen Raum, illustrieren die theoretischen Grundsätze.
