Blood composition of succinyldicholine culled elephants and buffaloes was compared with that of undisturbed animals shot in the brain. The results show statistically significant differences in a number of variables including plasma ACTH and cortisol concentrations. The observed changes are attributed to stress induced by a combination of herding and darting with succinyldicholine and asphyxia. Extrapolation from blood oxygen tensions suggests that this stress may be perceived for an undetermined period which is probably longer in elephants than buffaloes.

Resting metabolic rates (RMR) below thermoneutrality in adult hyrax acclimated to 26, 15 and 10 degrees C remained unchanged, i.e. thermal conductance (K) remained constant. Conductance in juveniles decreased with acclimation to lower ambient temperatures (Ta). Body temperature (Tb) dropped by 3.8 degrees C in adults exposed to Ta of 30-5 degrees C. The decrease was constant. Body temperature fell by 1.5 degrees C in juveniles exposed to Ta of 30-20 degrees C but stabilized between 20 and 5 degrees C. The labile Tb, associated with behavioural strategies and lower than predicted RMR, can be seen as an energy-conserving mechanism of particular importance during winter conditions.
