| density-dependent | <epidemiology> 1. Effects whose intensity changes with increasing population density. 2. Effects whose intensity increases with increasing population density, for example a mortality which becomes very high near a carrying capacity. Effects which become less pronounced at higher population sizes (perhaps the reduction in fecundity caused by the difficulty of mating) are sometimes called inverse density dependent. Density dependent effects are often a cause of nonlinearity in a model. (05 Dec 1998) |

| densovirinae | A subfamily of DNA arthropod viruses, in the family parvoviridae. The host range includes members of dictyoptera, diptera, lepidoptera, odonata, and orthoptera. There are three genera: densovirus, iteravirus, and contravirus. There is evidence that densovirus-like viruses also infect and multiply in crabs and shrimp. (12 Dec 1998) |
| densovirus | A genus of parvoviridae, subfamily densovirinae, comprising helper-independent viruses containing only two species. Junonia coenia densovirus is the type species. (12 Dec 1998) |
| density |
A measure of how heavy a solid, liquid, or gas is for its size. Density is expressed in terms of weight per unit volume, that is, grams per cubic centimeter or pounds per cubic foot. The density of water is 1.0 gram per cubic centimeter or about 62.4 pounds per cubic foot.
