Evergreen forests accumulate higher forest floor masses than deciduous in similar climatic zones. In needle-leaved forests, none of the climatic factors or latitude explains the variation in amount of aboveground litterfall mass or litterfall nitrogen (N) input. This is in contrast to the broad-leaved forests in which half of the variation in aboveground litterfall mass or litterfall N input is explained by latitude, mean annual temperature, minimum monthly mean temperature, or logarithmic transformations of precipitation. Lower total root masses were measured in cold temperate needle-leaved deciduous, Mediterranean needle-leaved evergreen, and tropical broad-leaved semi-deciduous forests while higher total mean root masses occurred in tropical broad-leaved evergreen forests. In the warm temperate zones, evergreen forests had similar mean total root masses whether broad-leaved or needle-leaved. However, deciduous forests averaged 5000 kg ha-1 less total root mass than evergreen forests. In cold temperate forests, the proportion of total detrital input to forest floor occurring as aboveground litterfall varied from 23 to 80%. Inclusion of root turnover as part of total litter input changed the calculated mean residence time of organic matter in the forest floor from 7.8 to 6.3 years in a red pine plantation and 68.6 to 15.7 years in a Pacific silver fir stand. |
