Pitch canker disease (Fusarium circinatum Nirenberg & O'Donnell) causes serious shoot dieback, reduced growth and mortality in pines found in the southern and western USA, and has been linked to nutrient imbalances. Poultry houses with forced-air ventilation systems produce nitrogen (N) emissions. This study analyzed spatial correlations between pitch canker disease and foliar, forest floor, so...

The energy distribution of natural rainfall droplets at different stages canopy development in low-latitude semi-arid environments is still understudied. We assessed relationships between development, gross (P) and throughfall (TF) characteristics a tropical dry forest (TDF) with total 95 events rain during December 2019–July 2021, Northeast Brazil. One disdrometer was installed an open field t...

In Western Africa, the growth of cities has led to natural resource pollution, especially air pollution. Urban forests play a key role in filtering atmospheric particles and pollutants through canopy before reaching soil. This study aims quantify heavy metal fluxes an urban forest district Abidjan order assess its protection resources. A monitoring wet deposition (throughfall open field rain) l...

Although it is well known that forest canopies reduce the amount and intensity of precipitation at the ground surface, little is known about how canopy interception modifies extreme events. This research investigated the effects of forest cover on intensity-duration-frequency relationships using a stochastic model to extrapolate measured rainfall and throughfall to throughfall expected during e...

A systematic collection of throughfall (rain passing through the canopies), stemflow (rain flowing over the stems), and soil percolates was carried out in a Acacia dealbata plantation during one year, and its allelopathic capacity was biotested using Lactuca sativa L. var. Great Lakes. The results showed an allelopathic effect related to flowers: Germination of L. sativa was inhibited 30% by th...

in this paper, effects of the structural parameters on the optical characteristics of an add-drop filter, consisting of two straight waveguides and a micro-ring resonator (mrr), have been investigated. in this research, effects of mrr radius, the width of mrr and waveguide and the gap between mrr and waveguide, on free spectral range (fsr) and coupling coefficient have been studied. it is found...

To date, there has been limited knowledge about how soil carbon dioxide (CO2) emissions from forest ecosystems at a global scale respond to the altered precipitation, and key influencing mechanisms involved. Thirty-seven studies conducted under throughfall manipulation conditions in around globe were selected this meta-analysis, with total of 103 paired observations. Experimental categories suc...

Tropical forests are a significant global source of the greenhouse gas nitrous oxide (N2O). Predicted environmental changes for this biome highlight the need to understand how simultaneous changes in precipitation and labile carbon (C) availability may affect soil N 2O production. We conducted a small-scale throughfall and leaf litter manipulation in a lowland tropical forest in southwestern Co...

The objective of this study was to examine the impact of summer throughfall on the growth of trees, at upland and floodplain locations, in the vicinity of Fairbanks, Alaska. Corrugated clear plastic covers were installed under the canopy of floodplain balsam poplar/white spruce stands and upland hardwood/white spruce stands to control soil moisture recharge as a result of summer precipitation. ...
