Prescribed fire, a practice applied annually to about 10(6) hectares of forests in the southeastern United States, had limited effects on soils, nutrient cycling, and hydrologic systems of a coastal plain pine forest. Hydrologic fluxes of nitrogen, phosphorus, sulfur, and basic cations, from burned pine litter to ground and stream waters, are not likely to(More)
Basal area and volume production in loblolly pine spacing trials in Hawaii were nearly double ' the average production in research plantings in the Southeastern United States. The higher productivity in Hawaii was associated, to some extent, with site index and more rapid growth of individual trees. Competition-related mortality, however, was considerably(More)
Moral norms are the rules of morality, those that people actually follow, and those that we feel people ought to follow, even when they don’t.
