Canopy Openness, Understory Light Environments, and Oak Regeneration
Understory light environments were evaluated in four mixed-oak forests in southern Ohio using hemispherical photography. Within each forest, plots were divided into nine treatment combinations based on three pretreatment fire categories and three Integrated Moisture Index (IMI) categories. For each of 108 photographs we determined the percentage of open sky, direct beam, and diffuse radiation; ...
متن کاملVariations in the sky brightness during a lunar eclipse
A total lunar eclipse is conjectured to have influence on the physical conditions of an environmental area, particularly on the brightness of the sky. The phenomenon might also be relevant on weather parameters change on Earth, such as temperature, humidity and pressure, though a straightforward correlation is not easy to establish. This work mainly aims at measuring the brightness of the sky a...
متن کاملCloud Cover Estimation Using Multitemporal Hemisphere Imageries
The solar radiation is the origin of energy for the photosynthesis and forest productivities. On the other hand, clouds constantly appear, move and disappear all the time and influence atmospheric and radiation conditions at the same time. Therefore, to understand cloud parameters which consist of cloud covers, its distributions and types etc. for a short time interval can help us to estimate s...
متن کاملForest Structure, Canopy Architecture, and Light Transmittance in Tropical Wet Forests
Identifying factors that influence variation in light availability within forested ecosystems represents an important component in our understanding of the complex determinants of tree seedling regeneration. We assessed the influence of forest structure and canopy tree architecture on spatial heterogeneity of understory light availability in three old-growth and three second-growth forests in l...
متن کاملDiverse Responses of Maple Saplings to Forest Light Regimes
Seedlings of 11 species of forest maples (Acer L.) were grown outdoors from budburst to senescence under three light regimes: ‘gap centre under clear skies ’ (approx. 20% open sky irradiance; red:far-red ratio ̄ 1±12) ; ‘gap centre under cloudy skies ’ (1±5%, ratio ̄ 1±03) ; and ‘gap edge’ (2±5%, ratio ̄ 0±6). Seedlings grown under the gap centre (clear sky) regime had significantly greater height...
