“…Thus, earthworms in tropical areas respire faster than those in temperate regions because of higher temperatures. There is some good evidence that earthworm respiration acclimatizes to temperature; thus when earthworms maintained at a low temperature were transferred to a higher temperature, they still respired more slowly than individuals that had been kept at a higher temperature previously (Kirberger, 1953;Saroja, 1959). There is experimental evidence of a diurnal rhythm of oxygen consumption, with maximal rates at about 6 a.m. and 7 p.m. (Ralph, 1957;Doeksen and Couperus, 1968).…”

“…If we do consider this 10 C to 20 C range as most representative of the earthworm's temperature response, a still lower C) is indicated. Kirberger (1953) conditioned specimens of Lumbricuius variqatus at 10 C, 16 C and 23 C and then measured the resultant Q^f^'s over the range 14 C to 24 C as 2.0, 2.0, and 1.83 respectively. In Figure 11 I have plotted the results of Kirberger's (1953) Rate of respiration in Eisenia foetida from data of Kirberger (1953) Rao and Bullock (1954) found that Q commonly increases with organism size as well as with habitat temperature.…”

The ice worm is smeller than the earthworms studied by Vernon and Kirberger, so if any correction factor were to be applied for purposes of comparison, it would increase the ice worm's Q to a figure that is higher yet.…”

“…( iv) The average of maximum and minimum temperatures measured in nature can be used to estimate respiration for that period of time ; Kirberger (1953) found that in a fluctuating temperature regime the oligochaete Lumbriculus variegatus responded as if it were at the average temperature. ( ii) Respiration rates measured in spring can be extrapolated to summer ; the long period of laboratory acclimation probably decreased errors due to seasonal acclimation, and results of preliminary experiments performed in February were comparable to those in April.…”

In the region of Barnstable Harbor, Massachusetts, 67 species of larger invertebrates were found in 3 faunal associations characteristic of different tide levels. The number of species per sample was highest at the intermediate tide level.Temperatures of sediments and densities of several species were followed for a year at two intertidal levels ( 60 em and 90 em above mean low water). Temperature variation was lower at the 60-cm level than at the 90-cm level at all times of the year, and at both levels was higher in spring than at any other time of the year. In three of the four species studied, spatial variation in density and rate of density change was significantly higher at the 60-cm location than at the 90-cm location. The mortality rate for adult G. gemma was higher at 60 em (where density was lower) than at 90 em, while the reverse was true for young-of-year. Release of young began sooner in the spring at 90 em than at 60 em.The growth rate of G. gemma at Barnstable Harbor was much lower than that reported at Union Beach, New Jersey, although at both places virtually all growth took place in summer. At Barnstable Harbor the maintenance requirements were 20-30 times higher in summer than in early spring. The Q 10 within the temperature range 5-2o•c was 4.1. G. grmma at 90 em had less time to feed than at 60 em, but had higher requirements for population maintenance because of an older age structure and a higher density. The growth rate of G. gemma was higher at 90 em than at 60 em. 1
