Effect of Temperature on the Development of Thelastoma bulhoesi (Oxyurata, Thelastomatida) and Other Nematodes
Abstract
Embryonation of Thelastoma bulhoesi was monitored at eight temperatures between 0 and 35 C. Cell division did not occur below 15 C or at 35 C. Development was most rapid at 25 and 36 C. The effect of temperature on the rate of embryological development of T. bulhoesi at different stages was measured using the temperature coefficient, Q[sub1][sub0]. The developmental temperature response curve obtained for T. bulhoesi was similar to enzyme temperature response curves. Our evidence supports the thesis that nematode embryonation, as affected by temperature, varies between species and between stages of development. Key words: temperature coefficient, Q[sub1][sub0].Downloads
