Measuring metabolic rates is central to important questions in many areas of scientific research. Unfortunately these measurements are anything but straightforward, and numerous pitfalls await the novice and even the experienced investigator. Measuring Metabolic Rates de-mystifies the field, explaining every common variation of metabolic rate measurement, from century-old manometric methods through ingenious syringe-based techniques, direct calorimetry, aquatic respirometry, stable-isotope metabolic measurement and every type of flow-through respirometry. Each variation is described in enough detail to allow it to be applied in practice. Background information on different analyzer and equipment types allows users to choose the best instruments for their application. Respirometry equations - normally a topic of terror and confusion to researchers - are derived and described in enough detail to make their selection and use effortless. Vital topics such as manual and automated baselining, implementing multi-animal systems, and the correct analysis and presentation of metabolic data are covered in enough detail to turn a respirometry neophyte into a hardened metabolic warrior, ready to take on the task of publication in peer-reviewed journals.
Seventeen short chapters with engaging narrative and lots of photos with information-packed captions illustrate the mechanisms by which birds produce the characteristic and sometimes brilliant coloration of their feathers and other body parts.

Edible insects have always been a part of human diets, but in some societies there remains a degree of disdain and disgust for their consumption. Insects offer a significant opportunity to merge traditional knowledge and modern science to improve human food security worldwide. This publication describes the contribution of insects to food security and examines future prospects for raising insects at a commercial scale to improve food and feed production, diversify diets, and support livelihoods in both developing and developed countries. Edible insects are a promising alternative to the conventional production of meat, either for direct human consumption or for indirect use as feedstock. This publication will boost awareness of the many valuable roles that insects play in sustaining nature and human life, and it will stimulate debate on the expansion of the use of insects as food and feed.
