..., whereas two or three HWs strongly reduced both final size and development time. One possibility is that oxidative damage or metabolite accumulation following multiple HWs exceeds a physiological threshold and reduces subsequent growth rate ( Feder and Hofmann, 1999 ; Harrison et al., 2012 ).

... was positively correlated with adult mortality but not nest predation rates among 43 songbird species on three continents. Nest predation, but not adult mortality, explained additional variation in growth rates beyond metabolism. Our results suggest that metabolism may not be the mechanism underlying...

... development on moderate to long-term performance indicators at temperatures spanning the optimal temperature for growth in the speckled cockroach, Nauphoeta cinerea . In contrast to the predictions of the OCLTT hypothesis, development under hypoxia did not significantly reduce growth rate or running...

... placed in cages with sawdust bedding, at 23°C and 12 h:12 h light:dark photoperiod, the standard housing conditions in our mouse colony. Each pup in a litter was individually marked and weighed every other day to determine its growth rate for the entire experimental period. On the 8th day of lactation...

... of individual-specific observations (range: three to nine observations/individual) from instar V growth trajectories, we used a method based on absolute growth rates [(mass increment)/(time interval); i.e. slope of the growth trajectory] between successive mass measurements in estimating the individual-specific...

... weaning, remained smaller at 10 weeks of age than those reared in smaller litters. Females from enlarged litters were consistently smaller throughout post-weaning development and showed no increase in growth rate compared with females from reduced litters. In enlarged litters, protein thiol concentration...

... Growth rate Macrobrachium rosenbergii Oxygen supply capacity Temperature Metabolism of resting, fasting animals (standard metabolic rate, SMR) increases exponentially as temperature rises, whereas maximal oxygen uptake typically plateaus or even decreases as the structural and physiological...

... growth rate in cold temperature results from both high 20S proteasome activity and a reduced rate of protein synthesis. The chymotrypsin-like activity of the 20S proteasome was affected by acclimation temperature. When measured at a common temperature, the activity in fish acclimated at 4°C was higher...

... and a faster size-specific growth rate, without a change in the developmental rate. Both lines had comparable food consumption but the selected snails grew more efficiently and had lower metabolism early in ontogeny. Attainment of lower metabolism was accompanied by decreased shell production, indicating...

...Thomas M. Clark; Benjamin J. Flis; Susanna K. Remold SUMMARY The effects of salinity on growth and development of the euryhaline Ochlerotatus taeniorhynchus and the freshwater Aedes aegypti are compared. O. taeniorhynchus grow larger, and have greater intrinsic growth rates, than A. aegypti...

...E. de Margerie; J.-P. Robin; D. Verrier; J. Cubo; R. Groscolas; J. Castanet SUMMARY Microstructure–function relationships remain poorly understood in primary bone tissues. The relationship between bone growth rate and bone tissue type, although documented in some species by previous works, remains...

...Dany Pelletier; Pierre U. Blier; Jean-Denis Dutil; Helga Guderley ABSTRACT The activity of glycolytic and oxidative enzymes was monitored in the white muscle of Atlantic cod Gadus morhua experiencing different growth rates. A strong positive relationship between the activity of two glycolytic...
