Adult copepods Centropages hamatus were induced to feed on 10 to 40 µm Sephadex beads by adding Thalassiosira weissflogii or Scrippsiella trochoidea whole-cell extract, or filtrate from a T. weiss flogii culture , to a bead suspension. Beads were neither ingested in the absence of a chemical stimulus, nor in the presence of filtrates from cultures of S. trochoidea and Olisthodiscus luteus , or 0. luteus extracts. Extracts from both S. trochoidea and 0. luteus, and filtrate from an 0. luteus culture, appear to exert an inhibitory …

Standard rates of 02 consumption (Vo2) in the dark of Varanus gi/leni (mean mass = 30 g) were measured at 25, 31, 34, and 37 C. At 37 C, the mean value (195 ml 02 STPD kg-1 h-1) was 22% lower than that predicted by a regression equation for lizards as a group (Bennett and Dawson 1976). Despite appearing to be asleep, three- to fourfold elevations in standard Vo2 were seen in lizards with lightweight, transparent respiratory masks. Vo2 was also measured during treadmill exercise at speeds from 5 to 15 …
