effect of temperature on its respiration even in

subtropical climate where seasonal temperature differences

are relatively minor. "Q10," the factor by which the

respiration rate is changed by a change of 10 degrees from

a baseline environmental temperature, is the measure of the

effect of temperature on a given organism. In this model,

the Q10 of prey fish was 1.3, and the baseline temperature

(Q10 = 1) was 27 C. The Q10 equation used in the model

expressed this relationship:



 Q10 = 1 + 0.03(T 27) (4)



 Bird respiration (rate equation 7 in Figure 13). Bird

respiration in the model decreased as a function of average

weight of the breeding birds and their young in order to

reflect the increased energy demands of the population when

rapidly growing young are being raised. An approximate

average size and average energy demand per gram body weight

of one stork and its young were calculated for each week of

the 9-wk nesting period, based on information from Kahl

(1962, 1964). A simple linear regression of respiration

versus average weight over this period formed the basic

formula for bird respiration used in the model:
