This number was considered as a cage density factor for analyses.
All the mice in a subgroup were housed in a single cage so as to create increasing cage densities of 4 to 16 mice/cage.
This analysis revealed that a factor even more important than mouse genotype was the experimenter performing the test, and that nociception can be affected by many additional laboratory factors including season/humidity, cage density, time of day, sex and within-cage order of testing.
Two- to three-day-old adult flies were collected with CO2 anesthesia and pooled in 1 L demography cages at a density of 100 125 flies per cage, with three independent cages per genotype.
The map shows the presence of dual regions at the top of the TBC-DEG cage density.
Crowd-reared locusts were kept in a separate room in 19 × 19 × 24 cm cages at a density of about 40 individuals per cage.
Larvae were reared in sleeve-like gauze cages, using 10 replicate cages per line and rearing temperature (resulting in a total of 240 cages), and a standard density of 20 20°CC) and 40 27°CC) larvae per cage, respectively.
The first experiment compared fry reared at the circular and cubic-shaped cages at a density of 100 fry/m3.
Juveniles weighing 5.84 ± 0.25 g (mean ± SD) were stocked in the cages at a density of 30 individuals per m2.
When irradiated larvae were eclosed, adult flies were collected over 48 h and randomly assigned to 500 mL demography cages to achieve a final density of 100 females and 100 males per cage.
