Dental decay among Australian children

More than 40% of Australian children aged 5 6 years had untreated decay (Table 2). The proportion of children with untreated decay varied among states and territories from 29.3% in the ACT to 49.7% in the NT. Consistent with previous results, children aged 5 6 years from the three lower SES areas had more untreated decay than children from

Tree seedling density was 4.6x higher on nurse logs than on the forest oor, which was likely due to competitive exclusion by H. splendens. Nurse logs had 17 species of bryophytes while the forest oor had six, indicating that nurse logs contribute to maintaining bryophyte diversity.
