Thus, the eight cages of one design were stacked in two horizontal lines of four cages in one rack, with cages of DBA/2NCrl and C57BL/6NCrl mice balanced for horizontal and vertical position in the rack, and each vertical pair of cages of C57BL/6NCrl and DBA/2NCrl mice was treated as a block, assuming greater microenvironmental similarity within blocks than between blocks.
Selection of lower- versus higher- slope values resulted in the segregation (to either subgroup) of mice within each pair of cage-mates, suggesting that mice within each pair were statistically not independent.
Logistic regression analyses were used to accommodate variation among cages to test the effects of the habitat, predation, sex, cage set (consisting pair of cages set approximately 1 m apart in the same larval site), and their interactions on the probability to produce M vs. S adult.
A total of 19 pairs of cages (38 cages in total) were set in nine puddles and in ten rice paddies during the rainy season of 2004 (May October 2004).
In each larval site, defined as a body of water where larvae of An. gambiae could be detected, two cages were placed approximately 1 m apart (pairs of cages in the same habitat were at least 10 m apart).
It is assumed that SMF could change the lifetime of radical pairs, yields of cage products, and escape products.
This population of birds has been bred (almost) exclusively in cages for at least 20 generations, with one force-paired pair per cage, thus minimising the opportunity for sexual selection to work.
From each cadaver spine, one motion segment was fixed with a pair of cylindrical cages (BAK, Sulzer Medica) and the other with paired rectangular cages (Rotafix, Corin Spinal).
In each compartment we placed a row of 11 mesh cages (7.5 × 2.5 × 2.5 cm), with a gap of 1.5 cm between each pair of adjacent cages.
Even though Stewart has dogs (Chow Chows named Paw Paw and Chin Chin) and Himalayan cats (females known as Teeny and Weeny, and males called Mozart, Verdi, Vivaldi, Berlioz, and Bartók), the house is dominated by American song canaries, which screech continuously inside a pair of antique cages.
A pair of large "bird cage" vases glazed in blue-and-white floral patterns have bent rods enclosing hollowed midsections once occupied by little ceramic birds.
