Blackwell Publishing and Nordic Society Oikos are collaborating with JSTOR to digitize, preserve and extend access to Oikos. Calcium, magnesium, nitrogen and phosphorus were measured in throughfall of an oak, marginal fen, and white cedar swamp forest in east-central Minnesota, U. S.A. Annual totals of calcium in throughfall of the oak, fen and swamp forest were 7. These totals were comparable with data in the literature. Calcium depositions in throughfall as per cents of the sum of throughfall and litter fall were 13, 10, and 10 per cent in the oak, fen and swamp forests respectively .

Requirements for throughfall monitoring: The roles of temporal scale and canopy complexity
A wide range of basic and applied problems in water resources research requires high-quality estimates of the spatial mean of throughfall. Many throughfall sampling schemes, however, are not optimally adapted to the system under study. The application of inappropriate sampling schemes may partly reflect the lack of generally applicable guidelines on throughfall sampling strategies. In this stud...
متن کاملInfluence of the Forest Canopy on Total and Methyl Mercury Deposition in the Boreal Forest
Atmospheric mercury deposition by wet and dry processes contributes mercury to terrestrial and aquatic systems. Factors influencing the amount of mercury deposited to boreal forests were identified in this study. Throughfall and open canopy precipitation samples were collected in 2005 and 2006 using passive precipitation collectors from pristine sites located across the Superior National Forest...
متن کاملThe ecology of energy and nutrient fluxes in hemlock forests invaded by hemlock woolly adelgid.
The hemlock woolly adelgid (HWA, Adelges tsugae Annand) is currently causing a severe decline in vitality and survival of eastern hemlock in North American forests. We analyzed the effects of light HWA infestation on vertical energy and nutrient fluxes from the canopy to the forest floor. Canopy throughfall, litter lysimeters, and laboratory litter microcosms were used to examine the effects of...
متن کاملLong-term effects of rainforest disturbance on the nutrient composition of throughfall, organic layer percolate and soil solution at Mt. Kilimanjaro.
At the lower parts of the forest belt at Mt. Kilimanjaro, selective logging has led to a mosaic of mature forest, old secondary forests ( approximately 60 years), and old clearings ( approximately 10 years) covered by shrub vegetation. These variations in the vegetation are reflected by differences in nutrient leaching from the canopy and in both amount and quality of litter reaching the ground...
متن کاملForest fire effects on mercury deposition in the boreal forest.
Particulate Hg (pHg) is a component of smoke from biomass burning and has the potential for local redeposition. Throughfall (precipitation collected beneath a conifer or deciduous canopy) and open precipitation samples were collected pre- and postfire in 2005 and 2006 using passive precipitation collectors across the Superior National Forest, located in northern Minnesota, USA. Samples were col...
