“…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.

“…Griseb. forests on poorly drained soil are burned or cleared, waterlogged conditions impair the recolonization of forests and stimulate Sphagnum colonization (Díaz et al 2007;Díaz and Silva 2012). These sites have been referred to as secondary or anthropogenic peatlands (Díaz et al 2008).…”

Background: Peatlands play a key role in the global carbon cycle; these contain one third of the world's soil organic carbon, equivalent to more than half the amount of carbon in the atmosphere. Nevertheless, these ecosystems have been scarcely studied in southern South America. The main objective of this paper is to evaluate the recent accumulation rates of carbon (C) and nitrogen (N) in two kinds of oligotrofic peatlands in Isla Grande de Chiloé (Chile). Results: Using peat C and N content, dry bulk density, and Pb-210 dating, we determined the rates of N and C accumulation in profiles from five peatlands in the northern Chilean Patagonia. The recent rate of C accumulation (RERCA) ranges from 8.5 to 87.06 g C m −2 year −1 , and the recent rate of N accumulation (RERNA) ranges from 0.15 to 2.37 g N m −2 year −1 . The difference in RERCA and RERNA between glacial peatlands and anthropogenic peatlands was significant. One of the remarkable results is that accumulation of N and C are directly related. Conclusions: This study contributes for a better understanding of the Patagonian peatlands of Chile. In addition, this research contributes by setting a basis for conducting further studies and for assessing the impacts of climate change on peatlands.

“…The Penman-Monteith equation is a well-established approach to estimating plant water use (Irmak et al, 2005;Cleugh et al, 2007), and it is easy to conduct a few simple simulations to show that water use by a crop depends strongly on windspeed and atmospheric coupling (e.g., Díaz et al, 2007), both of which may be influenced through forest management. However, few studies of plantation water use take windspeed into account (e.g., Cannell, 1999).…”
