The last review of soil respiration studies (.pdf) took place in 1992, however, and though it found a link between temperature and respiration rates, data was relatively sparse.

Instead of sticking sensors onto the skin, Philips has developed a vital-signs camera system which the Dutch company says can measure heart and respiration rates extremely accurately.

The ratios of the respiration rates of different sized plankton to corresponding sized phytoplankton production rates are: micro-, 175%;
