“…In view of the particularly large solute fluxes from mature babassu palms and considering that these palms occupy only 0.03% of the study area, the forest floor around babassu stems is likely a microsite with soil properties distinct from the bulk soil. Studies from a wide range of forest types provide evidence that sites that receive considerable amounts of stemflow tend to show a relatively low pH and high element turnover rates (Chang and Matzner, 2000a;Falkengren-Grerup and Björk, 1991). There is evidence from Rondônia forests that combination of higher soil moisture and high NO À 3 availability could create hotspots for denitrification and N 2 O emission (Garcia-Montiel et al, 2003).…”

“…Throughfall solute deposition patterns, for instance, show a temporal stability at scales of weeks to several months (Raat et al, 2002;Staelens et al, 2006;Zimmermann et al, 2008Zimmermann et al, , 2007. Stemflow-induced microsites, in contrast, persist for decades or even longer depending on the lifespan of the tree (Chang and Matzner, 2000a;Falkengren-Grerup and Björk, 1991). Because babassu palms have an average lifespan of 150-180 years (Pinheiro, 2004) the stemflow-induced microhabitat around these palms exists for more than a century.…”

“…Although stemflow-induced soil acidification has been widely reported for F. sylvatica (e.g. Falkengren-Grerup, 1989;Falkengren-Grerup and Bjork, 1991;Chang and Matzner, 2000), no known studies have documented stemflow-induced soil acidification for species having excurrent forms (e.g. Pinus), gentler branch inclination angles, and lower stemflow production values.…”

Abstract:Leaching is an important process in the biogeochemical cycling of nutrients from above-ground vegetative surfaces to the forest floor. Little is known about winter leaching from deciduous tree species and the influence of branch inclination angle on leachate chemistry. Using a set of field-based isolated branches harvested from mature crowns of Betula lenta, Carya glabra and Quercus rubra, we tested the null hypothesis that during winter neither branch inclination angle nor branch species would have a detectable influence on differences in leachate chemistry and the quantity of intercepted precipitation from the branch surface. Leachate concentrations were significantly greater from branches inclined at 20°than 5°or 38°. Absolute nutrient inputs were also greatest for branches inclined at 20°. The significantly enriched branchflow and greater total nutrient input from branches inclined at 20°were attributed to increased residence time of intercepted precipitation with the branch surface, the lower probability of branch drip than branches inclined at 5°, and only minimal differences in branchflow quantity compared with branches inclined at 38°. Branchflow was more enriched from all three branch angles during precipitation events of longer duration and lower intensity than shorter, intense events. The leachate quantities of K C and Ca 2C differ significantly among species. Carya glabra and Quercus rubra leached more K C than Betula lenta. All three species leached significantly different amounts of Ca 2C , with Quercus rubra leaching the most and Carya glabra the least. The adaptive geometry of deciduous canopy trees should be considered in relation to the interception of precipitation and aqueous leaching during winter when the canopy is leafless.

“…Stemflow, i.e. water running down along branches and stem, has been often considered to explain acidification of the stemflow area under beech [17,18,19,15,8,16], more especially in polluted countries [49,48,24,21,43]. Changes in litter quantity and quality under the canopy of trees have been also evoked, more especially the role of bark deposition [50,26,19].…”

Changes in the composition of humus profiles near the trunk base of an oak tree (Quercus petraea (Mattus.) Liebl.)

Humus profiles were sampled under the crown of a mature oak tree in a coppice with standards (Senart forest, 30 km south of Paris). The sampling design compared the composition of humus profiles at three distances of the trunk base (40, 140 and 240 cm) and in the four cardinal directions. An increase in the development of the OF layer (strongly decayed litter and faeces of epigeic fauna) was observed at 40 cm from the trunk base, paralleling an increase in soil titratable acidity. Since no significant change in litter composition occurred with distance to the trunk base and in the absence of stemflow reaching the ground during showers, diffusion of bark tannins from buried parts of the trunk and main lateral roots was suspected to negatively influence soil biological activity, particularly earthworm activity.
