“…A correlação negativa entre os parâmetros pode estar relacionada com o efeito de diluição dos íons em função dos volumes precipitados (LACLAU et al, 2003;CALIL, 2008), conforme já abordado anteriormente. Ao contrário do que alguns trabalhos da literatura evidenciaram (ZHANG et al, 2006;BALIEIRO et al, 2007), não ocorreu correlação positiva entre os teores de potássio e a PI (Tabela 3), talvez pelo efeito de diluição do íon nas amostras ao invés do processo de lixiviação em função da chuva. Scheer (2009) ).…”

“…Throughfall is the part of rainfall that reaches forest floor either through dripping from the tree canopies and after fulfilling initial interception storage or direct passing the canopy gaps (Chappell and Bidin, 2001;David et al, 2011;Díaz et al, 2007;Guswa and Spence, 2012;Huber and Iroumé, 2001;Rahmani et al, 2011;Roberts and Rosier, 2005;Wuyts et al, 2008;Zhang et al, 2006;Zimmermann and Zimmermann, 2014).…”

Elucidating segregation of precipitation in different components in forest stands is important for proper forest ecosystems management. However, there is a lack of information on important rainfall components viz. throughfall, interception and stemflow in forest watersheds particularly in developing countries. We therefore investigated the spatiotemporal variation of important component of throughfall for a forest stand in a Hyrcanian plain forest in Noor City, northern Iran. The study area contained five species of Quercus castaneifolia, Carpinus betulus, Populus caspica and Parrotia persica. The research was conducted from July 2013 to July 2014 using a systematic sampling method. Ninetysix throughfall collectors were installed in a 3.5 m × 3.5 m grid cells. The canopy covers during the growing/leaf-on (i.e., from May to November) and non-growing/leaf-off (i.e., from December to March) seasons were approximately 41% and 81%, respectively. The mean cumulative throughfall during the study period was 623±31 mm. The average throughfall (TF) as % of rainfall (TFPR) during leaf-on and leaf-off periods were calculated 56±14% and 77±10%, respectively. TF was significantly (R 2 = 0.97, p = 0.00006) correlated with gross precipitation. Percent of canopy cover was not correlated with TF except when gross precipitation was <30 mm. A comparison between leaf-off and leaf-on conditions indicated a significantly higher TFPR and corresponding hotspots during leaf-on period. TFPR also differed between seasons with a maximum amount in winter (82%). The results of the study can be effectively used by forest watershed managers for better perception of hydrological behavior of the Hyrcanian forest in the north of Iran under different silvicultural circumstances leading to getting better ecosystem services.

“…The dry deposition of the inorganic nitrogen was estimated by the multiple regression analysis proposed and later improved by Lovett and Lindberg (1984), Potter et al (1991) and Lovett et al (1996). The more detailed description of dry deposition calculation was given in Zhang et al (2006b).…”

Inorganic nitrogen deposition and leaching in stream water were monitored from January, 2001 to December, 2004 in a subtropical evergreen mixed forest in central-south China. The seasonal concentration and flux of inorganic nitrogen in bulk precipitation and stream water, seasonal mean net retention of nitrogen and net flux of H + transformed by nitrogen were estimated and quantified in Shaoshan forest. The research results show that the correlation coefficient of fluxes between bulk precipitation and stream water is significant, with a coefficient 0.916 at the 0.01 level. Mean fluxes of inorganic nitrogen input are 2.62 g m −2 a −1 and 0.516 g m −2 a −1 in form of bulk precipitation and dry deposition respectively, and output in stream water is around 0.22 g m −2 a −1 , which indicates that most of nitrogen input is reserved in the forest. Net retention of nitrogen reaches 2.916 g m −2 a −1 , just higher than other study plots over the world. Along with the translating of nitrogen (NH þ 4 À N and NO À 3 À N), H + is imported to the forest ecosystem at the same time. At our study plots, net flux of H + transformed by nitrogen is about 73.57 mmol m −2 a −1 . The positive value suggests that Shaoshan forest is still a finer buffering system to nitrogen deposition and it is far from nitrogen saturation in spite of the high nitrogen deposition.
