“…1, and 16.8% of the gross rainfall for the entire study period. Park (2000) indicated that total basal area was the primary factor controlling the difference in the ratio of throughfall and stemflow between two stands in the region, considering the various species present (Brown and Barker, 1970;Prebble and Strick, 1980;Valente et al, 1997;Crockford and Richardson, 1990). The relationship between total basal area and each ratio was also valid at this site, implying that the ratio of interception loss at a stand may be mainly determined by basal area, regardless of size distributions or stand density.…”

“…Consequently, the effects of one factor can be confounded with the effects of the other. In any case, as just suggested, there may be a correlation of intensity and stemflow delivery only in certain intensity classes, and this might be concealed when event means are examined.A third group of studies has reported that stemflow yield rises under increasingly intense rainfall (Prebble and Stirk, ; Van Elewijck, ; Crockford and Richardson, ; Aboal et al ., ; Owens et al ., ). For instance, Aboal et al .…”

Laboratory rainfall simulation experiments using a small artificial olive tree are used to show that the fraction of rain falling at a constant intensity that becomes stemflow rises from 9% at 2.5 mm/h to 36.1% at 35 mm/h. Natural rainfall events commonly exhibit wide fluctuations of intensity. Simulated rainfall events each having a mean intensity of 10 mm/h, but containing short intensity peaks of 20 to 100 mm/h at varying intra-event positions, were used to explore the effect of varying intensity profiles. Results demonstrate that changes in rainfall event profile are associated with wide variation in stemflow flux, stemflow volume and stemflow fraction. When applied to an initially dry plant, rainfall events with a late intensity peak yielded an average peak stemflow flux up to 188% larger than events of contrasting profile, such as early peak events. The increase was smaller, up to 141%, when rain was applied to plants that were already partially wet, but was again found in events with a late intensity peak. Moreover, such events yielded a peak stemflow flux up to approximately seven times larger than comparable events of uniform intensity. Likewise, changing event profile with no change in rainfall depth was associated with a maximum stemflow fraction that was 31% larger than theminimum stemflow fraction, and a maximum stemflow volume that was nearly 37% larger than the minimum stemflow volume. These results suggest that rainfall event profile exerts a significant effect on all of the studied stemflow parameters. It is hypothesized that this is a consequence of the way in which intensity profile affects the rate of wetting-up of trickle pathways on the plant, and variation in the time taken for these pathways to become fully connected. Event profile must therefore be considered along with plant architecture in seeking to understand stemflow.

“…Th is process can be responsible for leaching nutrients from canopy leaves and transporting them to the forest fl oor (Parker 1983). In some particular cases, throughfall may exceed incident precipitation in quantity, e.g., under fog precipitation (Zinke 1962;Banaszak 1975;Prebble & Stirk 1980). Th roughfall includes incident precipitation which penetrates canopy gaps unless the individual canopy gaps are large and frequent (Parker 1983).…”

Litterfall, precipitation and nutrient fl uxes in a secondary lowland rain forest in Ile-Ife, Nigeria RESUMO (Queda de serrapilheira, precipitação e fl uxo de nutrientes em uma fl oresta pluvial secundária de terras baixas em Il-Ife, Nigéria) Produção de serapilheira, precipitação e o fl uxo de nutrientes foram investigados em uma parcela de 0,25 ha de uma fl oresta pluvial secundária de terras baixas em Ile-Ife, Nigéria, por um período de um ano. O estudo determinou a magnitude dos fl uxos de nutrientes através da serrapilheira, da chuva incidente, da interceptada, da escoada pelo tronco, e também avaliou a importância relativa desses componentes como vias de transporte de nutrientes para o solo desta fl oresta. Houve variação mensal signifi cativa na produção e acúmulo de serapilheira com maiores valores ocorrendo de novembro a março. A concentração de elementos em tanto na chuva interceptada como na escoada pelo tronco foram maiores que na chuva incidente. Maiores quantidades de cálcio, magnésio, ferro, cobre, zinco e nitrogênio foram depositados anualmente a partir da serrapilheira no chão da fl oresta, enquanto maiores quantidades de mercúrio, potássio, sódio, fósforo, chumbo e enxofre foram depositados através de precipitação. Ocorreu lixiviação de todos os elementos pela passagem da precipitação pelo dossel com a exceção de cobre, íons de hidrogênio, e chumbo, que foram retidos no dossel. Como conclusão este estudo mostra que a serapilheira é a principal via para a ciclagem de cálcio, magnésio, nitrogênio e todos micronutrientes investigados. A precipitação é o principal via para a ciclagem de potássio, fósforo, enxofre e traços de metais tóxicos (mercúrio e chumbo) na fl oresta. Palavras ABSTRACT(Litterfall, precipitation and nutrient fl uxes in a secondary lowland rain forest in Ile-Ife, Nigeria). Litterfall, precipitation and nutrient fl uxes were investigated in a 0.25 ha plot of a secondary lowland rain forest in Ile-Ife, Nigeria, for a period of one year. Th e study determined the magnitude of nutrient fl uxes through (litterfall, incident rainfall, throughfall and stemfl ow) and evaluated the relative importance of these components as pathways of nutrient transport to the soil of this forest. Th ere was a signifi cant monthly variation in litterfall and the highest values of the standing crop of litter occurred from November to March. Th e concentration of elements in both throughfall and stemfl ow were higher than those of incidence rainfall. Greater quantities of calcium, magnesium, iron, zinc, copper and nitrogen were deposited annually from the forest fl oor while greater quantities of mercury, potassium, sodium, phosphorus, lead and sulphur were deposited via precipitation. Th ere was net leaching of all elements from the canopy as precipitation pass through it with the exception of copper, hydrogen ions and lead, which were retained in the canopy. Th e fi nding of this study shows that litterfall is the major pathway for the cycling of calcium, magnesium, nitrogen and all micronutrients inve...
