title: Calorespirometry of terrestrial organisms and ecosystems.
abstract: Calorespirometry is the simultaneous measurement of heat and gas exchange from biological systems. Such measurements can be used to assess fundamental properties of many different types of systems from small ecosystems to isolated tissues. Techniques for calorespirometric measurements on terrestrial (non-aquatic) samples are described. Methods and models for evaluation of carbon conversion efficiencies, growth rates, and responses to environmental variables from calorespirometric measurements are described. A realistic model of the system under study is essential in the evaluation. Calorespirometry allows testing of models for tissues, individual organisms, and ecosystems.
