Breakdown of Confined and Nonconfined Oak Litter

Seasonal patterns in decomposition and nutrient release from East African savanna grasses grown under contrasting nutrient conditions

“…We acknowledge that the use of the 2-mm litter bags in this study could have altered the litter micro-climate (Meentemeyer, 1978;Witkamp and Olson, 1963) and excluded the larger macrofauna (Elkins and Whitford, 1982), thus reducing the fragmentation of the leaves and causing the bagged leaves to decompose at a different rate compared to non-confined leaves. Our study assumes that these effects did not mask the differences resulting from climatic conditions and litter quality.…”

Conifer needle processing in a subalpine lake 1

“…Sedell et al 1975;Mathews and Kowalczewski 1969;Witkamp and Olson 1963) to measure the weight loss of needles introduced onto lake sediments. This would also allow comparison with reported needle processing rates in streams.…”
