... driven by too high of a temperature, and severe hypoxia driven by an inadequate oxygen concentration. We compared the following traits in normoxia- and hypoxia-exposed rotifers: nuclear size (a proxy for cell size), body size, specific dynamic action (SDA, a proxy of aerobic metabolism) and two fitness...

... Postprandial SDA Anemia Burmese pythons ( Python bivittatus ) ( Kuhl, 1820 ), like many large snakes, utilize an intermittent ‘sit-and-wait’ feeding strategy, where prolonged fasts are punctuated by brief and voracious feeding bouts when prey is available. Digestion of these large meals (up to 25–100...

... during eating. After eating, the magnitude of SDA during digestion was evaluated ( Fig. 3 ). When PDBA xz was recorded, V̇ O 2 was significantly higher during digestion (paired t -test; t (7) =3.24, P <0.05), but there was no difference in PDBA xz (paired t -test; t (7) =1.28, P...
