“…Regarding oak litterfall rates, information is even more limited. The values obtained are below the scarce studies carried out in Spain (Gallardo et al, 1998;Pardo et al, 1997) with this almost endemic tree species, and slightly lower than results from a recent study of Quercus canariensis Willd., 1.5-1.6 Mg C ha -1 year -1 (Aponte et al, 2010). Our values are within the range of some studies made on evergreen Quercus ilex L in Spain (Bellot et al, 1992;Martin et al, 1996), but far below with results from Q. ilex in Central Italy (Bussotti et al, 2003).…”

“…It is somewhat surprising that in some studies it is reported that no-needles litterfall was negligible (Kavvadias et al, 2001;Roig et al, 2005). Oak leaves contributed to about 50% to total oak-derived litterfall, a much lower value than other studies on Q. pyrenaica (Gallardo et al, 1998), Q. ilex (Rapp et al, 1999) or Quercus robur L. (Díaz-Maroto and Vila-Lameiro, 2006;Hansen et al, 2009;Vesterdal et al, 2008). The only studies with similar relative contribution of leaves to total litterfall were those in which a high proportion of acorns was found (Callaway and Nadkarni, 1991;Díaz-Maroto and Vila-Lameiro, 2006), but that was not our case during the sampling period.…”

“…The information related to Pyrenean oak (Quercus pyrenaica Willd.) is much more scarce, with data from one single location in the whole Iberian Peninsula (Gallardo et al, 1998), although this tree species covers several hundred thousand hectares in the Iberian Peninsula (Ministerio de Medio Ambiente, 1998).…”

Aboveground litterfall from Pyrenean oak (Quercus pyrenaica Willd. a semi-deciduous species), mixed Pyrenean oak-pine and pine (Pinus sylvestris L.) forest stands was surveyed in two sites in a Mediterranean mountain area during a period of 36 and 29 months, respectively. Separation in different litterfall fractions was performed, and C content of each fraction was measured to calculate the C flux to the soil due to litterfall. Our results showed that litterfall input was higher in pine stands than in Pyrenean oak stands (1.8-2.4 Mg C ha -1 year -1 at pine plots and 0.9-1.4 Mg C ha -1 year -1 at oak plots) and mixed plots showed intermediate values. Needles or leaves contributed about 50% to total litterfall, underpinning the importance of the rest of materials in the soil C input. The seasonal pattern showed a maximum in Pyrenean oak stands in autumn-early winter, while the pine stands had the maximum in summer, which is in consonance with the physiology of fall of broadleaves and coniferous trees in these latitudes , but clearly differs from needle-shed in Central and Northern Europe. A dry-spring year corresponded to a lower leaf fall during the following autumn, and leaf abscission came some weeks earlier than a year with a rainy spring.Key words: litterfall; Pinus sylvestris; Quercus pyrenaica; ecotone; Mediterranean mountain. ResumenCaída de hojarasca en un ecotono Pinus sylvestris L.-Quercus pyrenaica Willd. en la Sierra de Guadarrama La tasa de caída de hojarasca en parcelas puras de rebollo (Quercus pyrenaica Willd.), parcelas mixtas de rebollo y pino silvestre y parcelas puras de pino (Pinus sylvestris L.) fue estudiada en dos localizaciones de montaña mediterránea durante 36 y 29 meses, respectivamente. Se llevó a cabo una separación de los componentes de la hojarasca, y se determinó el porcentaje de C en cada una de las fracciones, para calcular un flujo de entrada de C al suelo debido al desfronde. Nuestros resultados muestras que la tasa de caída de hojarasca fue más alta en parcelas de pino que de rebollo, alrededor del doble (1.8-2.4 Mg C ha -1 año -1 en pino frente a 0.9-1.4 Mg C ha -1 año -1 en rebollo); las parcelas mixtas mostraron valores intermedios. Las acículas u hojas contribuyeron alrededor del 50% al total de caída de hojarasca. El patrón estacional mostró un máximo de caída de hojarasca de rebollo en otoño y comienzos de invierno, mientras que en las parcelas de pino, dicho máximo se produjo en verano, lo que es congruente con la fisiología de la caída de hojas o acículas en frondosas y coníferas en estas latitudes, pero desmarcándose de los valores obtenidos en Europa Central y del Norte. Un año con primavera seca coincidió con un desfronde de hojas de rebollo menor; asimismo, la caída de la hoja se adelantó algunas semanas con respecto al año con una primavera lluviosa.

“…In the case of the mono-specific S. humboldtiana forest, there is an evident late spring pattern and the litterfall production coincides with the end of the flooding phase (Neiff and Poi de Neiff, 1990;Zamboni and Aceñolaza, 2004). In these forests a phenological reaction of trees seem to occur in response to the flood pulse, which may have deep effects in the dynamics of biogeochemical cycles and, hence, in nutrient release toward the soil (Gallardo et al, 1998).…”

Abstract• The objectives of this study were to measure litterfall production of the four floodplain forest types and to analyze the relationship between litterfall (forest type, dominant species, and organic fractions) and flood pulses.• Litterfall production was measured in two mono-specific stands of Salix humboldtiana or Tessaria integrifolia, respectively, and two mixed forests dominated by A. inundata or Nectandra angustifolia, during 1998 and the 2000-2002 periods.• Mono-specific stands presented similar productivities (6.8 and 6.5 Mg dry matter ha −1 y −1 , respectively), but differed significantly from the two other. The highest litterfall production was obtained during the large flood that occurred during 1998, decreasing later throughout the study period. Leaves were the dominant fraction of litterfall, followed by branches, flowers, and fruits.• Only S. humboldtiana, T. integrifolia and A. inundata forests showed distinct patterns of litterfall production, depending on the flooding pulse. N. angustifolia did not show a distinctive litterfall pattern.• The forests studied here presented patterns of litter production associated with the flood pulse according to its location along a topographic gradient, that controls the litter productivity of these forests.

“…Studies regarding better knowledge of these forest ecosystems have been previously performed (e.g., [1,8,9,10]), mainly focused on biogeochemical cycles of nutrients. Gallardo et al [8] observed different values of Open Access *Correspondence: juanf.gallardo@csic.esproduction of these deciduous oak forests according to different areas; these differences seemed to be inversely related to the amount of annual rainfall, which caused differences in soil acidity.…”

Deciduous oak coppices (Quercus pyrenaica Willd.) of the "Sierra de Gata" mountains (central western Spain) are located on acid rocks and subjected to annual rainfall higher than 700 mm year −1 . Accordingly, the soils are acidic (soil pH is often below 5.0) and feature the presence of Mn 2+ and Al 3+ in the exchangeable complex. The aim of the present study was to assess the response of these soils to the addition of a lime residue from a sugar beet mill to reach pH values close to 7.0 and 6.0 with in situ and in vitro experiments, respectively. Initially, the quality of the lime by-product was evaluated, which showed content close to 75 % CaCO 3 . Based on that analysis, calculations were accomplished to determine the dose of lime by-product necessary for achieving the targeted soil pH. We first performed an in vitro liming experiment, incubating 0.50 kg soil (0-20 cm layer) with 23.92 g CaCO 3 kg −1 soil (20 °C and soil moisture equivalent to that of field capacity). Subsequently, another experiment was done adding an equivalent quantity of sub-product in lieu of the pure CaCO 3 ; the factors monitored were: soil pH, exchange acidity, CEC, and exchangeable bases, every 24 h. The in situ experiment was performed in a forest plot located in Western Spain (Navasfrías), liming with 16.0 Mg DM by-product ha −1 (September 1999). Soil samples (two depths: 0-10 and 10-20 cm) were taken from both the control and the experimental forest plots for monitoring the liming effect. Sampling dates were September
