Temporal fluctuations in throughfall carbon concentrations in a spruce forest
Fluxes of nutrients, energy and ions through forest canopies are spatially and temporally highly heterogeneous and good modelling tools are needed to separate different influential variables. Two important factors affecting the variation in the throughfall fluxes are the amount of precipitation and phytophagous insects in the canopy. In spite of their large abundance, wide distribution and prod...
متن کاملThroughfall in a Puerto Rican lower montane rain forest: A comparison of sampling strategies
During a one-year period, the variability of throughfall and the standard errors of the means associated with different gauge arrangements were studied in a lower montane rain forest in Puerto Rico. The following gauge arrangements were used: (1) 60 fixed gauges, (2) 30 fixed gauges, and (3) 30 roving gauges. Stemflow was measured on 22 trees of four different species. An ANOVA indicated that m...
متن کاملSpatial variability of throughfall water and chemistry and forest floor water content in a Douglas fir forest stand
This study focuses on spatial variability of throughfall water and chemistry and forest floor water content within a Douglas fir (Pseudotsuga menziesii, Franco L.) forest plot. Spatial patterns of water and chemistry (NH4 +, NO3 -, SO4 2-, Cl-, Mg2+, Ca2+, Na+ and K+) were compared and tested for stability over time. The spatial coefficient of variation (CV) was between 18 and 26% for amounts o...
متن کاملSoil moisture variability in a temperate deciduous forest: insights from electrical resistivity and throughfall data
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...
متن کاملA linear system model of dynamic throughfall rates beneath forest canopies
[1] This paper describes a black box, linear system model to predict time-varying throughfall rates using only data of time-varying rainfall and storm total throughfall. For two forest stands in the Pacific Northwest the model predicted throughfall with mean efficiency of 0.84 when calibrated individually to 48 rainstorms and mean efficiency of 0.82 when calibrated to all storms simultaneously....
