Acidic substances, specifically sulfur (S) compounds, derived from atmospheric deposition play a major role in the acidification of forest ecosystems. This study conducted field surveys to clarify buffering system against seasonal large S inputs forested catchment central Japan that has historically suffered transboundary air pollution. Results showed fluxes significantly increased winter due n...

Abstract Forest decline, which occurs in mountainous regions many countries, may result from the effects of acid fog, ozone, or deposition other pollutants. We observed wet air pollutants at different altitudes on Mt. Oyama, situated southwest Tokyo, for 1994 until 2019. During this period, domestic atmospheric environment was improved Japan. The average concentration around all sampling sites ...

Canopy interception, throughfall, stemflow, and runoff have received considerable attention during the study of water balance and hydrological processes in forested ecosystems. Past research has either neglected or underestimated the role of hydrological functions of litter layers, although some studies have considered the impact of various characteristics of rainfall and litter on litter inter...

Terrestrial invertebrate carcasses are an important resource for insects developing in pitcher plants. However, little is known of the role of these carcasses in other containers, which also receive leaf fall and stemflow inputs. This experiment investigated effects of accumulated invertebrate carcasses as a resource for two competing mosquitoes, Aedes albopictus (Skuse) and Aedes aegypti (L.),...

Many hydrological studies of forested ecosystems focus on the study of the forest canopy and have partitioned gross precipitation into throughfall and stemflow. However, the presence of forest litter can alter the quantities of water available for soil infiltration and runoff. Little information exists regarding the value of storage and drainage parameters for litter layers. Vegetation paramete...

The partitioning of bulk precipitation (PR) in forest ecosystems and its chemical composition depends on both meteorological factors, such as amount intensity, evaporation rate, wind speed, stand structural density, canopy structure, bark texture, spatiotemporal distribution density foliage. We analysed fluxes water element contained therein a mature European beech (Fagus sylvatica L.) sandy so...
