[‚en·də′thər·mik]
(nuclear physics)
Petaining to a nuclear or particle reaction in which some of the kinetic energy of the initial particles is converted to mass energy.

2-9 endothermic effects at 90, 140, 172, 209, 338, 357, 367, 435, 735[degrees]C; 8 exothermic at 295, 395, 408, 480, 570, 598, 791, 820[degrees]C; thermal effects were accompanied by weight loss: at 80-500[degrees]C, when it amounted to 2.
Comparing melanosomes of 181 extant specimens, 13 fossil specimens and all previously published data on melanosome diversity, the researchers found that living turtles, lizards and crocodiles, which are ectothermic (commonly known as cold-blooded), show much less diversity in the shape of melanosomes than birds and mammals, which are endothermic (warm-blooded, with higher metabolic rates).
