Energy metabolism enhancement is a known adaptive response to stress situations and Caenorhabditis elegans is a typical model organism to study the effects of environmental influences on biological systems. Eggs and worms were either exposed to 0.5 mT (group 1), 1 mT (group 2), 2 mT (group 3), 3 mT (group 4) or not exposed (control group). All results were obtained from at least 3 replicates of the tests.
effects on the reproductive system: hatching rate (after 72 hours; number of hatched worms from same amount off eggs), brood size (after up to 4 days; daily progeny number and total progeny number) (in group 4)
mortality (in group 4; until all worms were dead (30 days), exposure either for the first 12 h, 24 h, 36 h or 48 h or over the whole test duration; counting of moving (=living) worms every second day); food consumption (in group 4 after 72 h; quantification of consumed bacteria)
