Temperate forest ecosystems are exposed to a higher frequency, duration and severity of drought. To promote longevity in changing climate, we require better understanding the long-term impacts repetitive drought events on fine-root dynamics mature forests. Using minirhizotron methods, investigated effect seasonal single-species mixed-species arrangements Fagus sylvatica (European beech) Picea a...

[1] Patterns of DOC and nitrate (NO3 ) concentrations and fluxes were studied for six storm events across four forested, glaciated, subcatchments (1.6 to 696 ha) in western New York, USA. End-member mixing analysis (EMMA) showed that catchment runoff was composed of shallow groundwater (SGW) discharged at seeps and throughfall (THF) on the rising limb and THF and riparian water (RW) on the rece...

A 2-year study (2010-2011) of fluorides in atmospheric precipitation in the open area and in throughfall in Wielkopolski National Park (west-central Poland) showed their high concentrations, reaching a maximum value of 2 mg/l under the tree crowns. These high values indicate substantial deposition of up to 52 mg/m(2)/year. In 2011, over 51% of open area precipitation was characterized by fluori...

Larix gmelinii forest is one of the dominant types in boreal and plays a unique eco-hydrological role terrestrial ecosystem. However, throughfall variability ecosystems, which crucial regulating hydrology, remains unclear. Here, we investigated spatial temporal stability within full leaf stage Great Kingan Mountain, Northeast China, effects rainfall properties canopy structure on were systemati...

*Deep root water uptake in tropical Amazonian forests has been a major discovery during the last 15 yr. However, the effects of extended droughts, which may increase with climate change, on deep soil moisture utilization remain uncertain. *The current study utilized a 1999-2005 record of volumetric water content (VWC) under a throughfall exclusion experiment to calibrate a one-dimensional model...

In deciduous forests, soil moisture is an important driver of numerous physical, microbial, and biogeochemical processes. Therefore, characterizing the interactions between vegetation and soil moisture is critical to forecast long-term water resources and ecosystem health. However, these interactions are difficult to measure, both in time and space. Recent studies have shown the ability of elec...

The aim of this paper was to estimate the influence of deposition of N, Mg, P, S, K, Ca, Mn, Fe, Co, Ni, Cu, Zn Cd, and Pb from under canopy in comparison with open space waters on the elemental composition of the moss layer to test the hypothesis that Pleurozium schreberi (Brid.) Mitt. and Hypnum cupressiforme Hedw. growing under the influence of canopy throughfall of Quercus robur contain hig...

Elevated emissions of sulfur dioxide, nitrogen oxides and ammonia in China have resulted in high levels of sulfur and nitrogen deposition, being contributors to soil acidification, especially in and near large cities. However, knowledge gaps still exist in the way that large cities shape spatial patterns of acid deposition. Here, we assessed the patterns of pH, sulfate, nitrate and ammonium in ...

Hydrological behavior in reforested watersheds is different from that under other forms of cover. The variation may be related to aspects intrinsic species, planting density, physiological maturity, management system and climatic conditions. Periodically, anomalies such as the case La Ninã are observed, these responsible for alteration rainfall regime consequently generate water deficits southe...
