There remains great uncertainty about how much tropical forest canopies contribute to global species richness estimates and the relative specialization of insect species to vertical zones. To investigate these issues, we conducted a four-year sampling program in lowland tropical rainforest in North Queensland, Australia. Beetles were sampled using a trap that combines Malaise and flight interce...

The aim of this study is to assess the canopy rainfall interception, surface detention storage, and soil moisture fluctuation in a micro-catchment coffee plantation. Field measurements were carried out using 15 funnel-type ordinary rain gauges an experimental area 30 m × measure passing through upper lower estimate interception throughfall. Rain placed at different locations account for variabi...

Development of the effective canopy architecture management for optimum light interception, and planting density on significant yield fruit quality Litchi cv. Shahi was investigated. The litchi Shahi, planted in square system at 2 × 2, 3 3, 4 4, 5 5, 6 8 m (control), showed average interception higher upper part canopy. Flowering attributes (number panicles, panicle length, number flowers yield...

Stand age is an important structural determinant of canopy transpiration (E(c)) and carbon gain. Another more functional parameter of forest structure is the leaf area/sapwood area relationship, A(L)/A(S), which changes with site conditions and has been used to estimate leaf area index of forest canopies. The interpretation of age-related changes in A(L)/A(S) and the question of how A(L)/A(S) i...

Plant photosynthesis and biomass production are associated with the amount of intercepted light, especially light distribution inside canopy. Three virtual canopies (n = 80, 3.25 plants/m2) were constructed based on average leaf size digitized plant structures: ‘small leaf’ (98.1 cm2), ‘medium (163.0 cm2) ‘big (241.6 cm2). The ratios diffuse set in three gradients (27.8%, 48.7%, 89.6%). simulat...

In this work we tested techniques suitable for a future validation of the RATP model to simulate transpiration and photosynthesis of mature olive trees under field conditions. Canopy architecture was characterised with an electromagnetic 3D digitiser and the software 3A. Although the capability of the software to deal with big data sets has to be improved, the system seems to meet the RATP requ...

Leaf area index (LAI) and plant area index (PAI) are common and important biophysical parameters used to estimate agronomical variables such as canopy growth, light interception and water requirements of plants and trees. LAI can be either measured directly using destructive methods or indirectly using dedicated and expensive instrumentation, both of which require a high level of know-how to op...

i-Tree Streets/Design and Eco estimate annual rainfall interception by urban forest based on different physics-based water balance models. Streets/Design is based on Xiao et al. (1998), while Eco is based on Wang et al. (2008) and improved by Hirabayashi (2013). In Xiao et al. (1998), annual rainfall interception percentage against the gross precipitation in Sacramento County, CA was estimated ...

The Persian oak, Quercus brantii, trees in the Zagros region of Western Iran have been in decline since 2000. The decline is assumed to be highly connected with changes in meteorological parameters. Our objectives were to quantify the long-term trends in meteorological parameters and reference evapotranspiration (ET0) in the Zagros region and estimate ecohydrological parameters highly affected ...

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...
