In all cases, the healthy control plants exhibited larger canopies with higher overall biomass and chlorophyll concentrations, as compared with the nutritionally stressed plants. Each sample consisted of leaves picked from different heights in the tree canopies. Quantifying the deciduousness of tropical forest canopies under varying climates. Lintels, canopies and balconies form continuous horizontal lines at floor level. Spectral estimation of absorbed photosynthetically active radiation in corn canopies. On bare soil 39% of both the dung-covered and buried seeds germinated, in perennial grass swards 24-43%, and under tree canopies 10- 24% respectively. Two living trees that had broken canopies and no leaves were neither collected nor identified to morphospecies, but they were counted and measured. The lowest survival and growth of seedlings was under conspecific tree canopies. From year 14, strong competitive interactions occur among poplar trees due to the closure of canopies. Absorption of radiation by canopies and stand growth. The objective of this study was to determine the time course of leaf area index and closure of oil palm canopies. Within-row tree canopies were closed throughout the period of study. To date, surprisingly little is known about the flight activities and daily movements of insects in the canopies of crops. The large autumn crops maintained their relative status during winter and went on to produce large spring canopies with large floral layers. Of the three plants tested, pepper canopies were the easiest to image from the nadir position, and tomatoes were the most problematic. The 150-band hyperspectral imager and the tungsten-halogen lamps were positioned at 90x off-nadir and approximately 90 or 120 cm, respectively, from the crop canopies. Epiphytic bryophytes can comprise a substantial amount of the biomass in forest canopies but few studies have examined their contribution to nutrient cycling. Explaining the abundance of ants in lowland tropical rain forest canopies. Seedling establishment is poor under tree canopies and in grasslands, but better in bare soil (c). The objective of the study was to assess the potential of the species for growth under forest canopies and to identify their habitat preferences. When canopies close, strong competitive interactions occur among poplar trees in the stand. In addition, the overstorey canopies protect streamwater from direct sunlight, thus maintaining stream temperature and protecting aquatic flora and fauna. Increased understanding of the factors affecting arthropod distribution in forest canopies can be used to improve sampling efforts for biodiversity assessment. Tree canopies were closed throughout the study period with virtually no undergrowth. The upper storey is broken and lower canopies merge to become almost continuous. As does the fact that sandalwood does not grow in forest with closed canopies but needs sunlight in order to thrive. First, the frequency in illuminating plant canopies might be reduced in number and duration. However, with such an approach, nadir imaging of crop canopies is almost impossible. Thus, hyperspectral data could be collected of symptomatic tissues independent of the complex plant canopies that were exhibited by the tomato plants. Unendurably high litter loads are most likely to occur directly under productive higher plant canopies where few seedlings emerged. The even-aged, homogeneous canopies of secondgrowth forests have small gap sizes and high frequency of microsites at intermediate light levels. Fire reduces the size of individual tree canopies more when they are further apart than when they are close together. Moreover, throughfall estimation assumes that canopies are locally uniform in distribution of leaf area and water retention properties. Thus, if epiphytes strongly influence spider composition, it is possible that they indirectly influence the arthropod faunas of tropical canopies. A modified rope-climbing technique for reaching canopies of forest tree in remote areas. The true dimensions of the canopy's contribution to the arthropod fauna of tropical rain forests has been investigated in only a few studies to date. Indirect effects resulting from plant-microbe interactions may represent an important neighbourhood effect acting on scales significantly larger than individual tree canopies. Stevens (1987) suggests that lianas impact host canopies by constricting growing twigs and branches and reducing fecundity. Ground absorption is higher and non-foliar absorption is lower in canopies in the moisture-limited plots. Thus, the reflectance signatures off of young and incompletely closed canopies will likely be very complex, and may not represent typical reflectance spectra from fully closed canopies. They have double-height zones with large windows facing eastwards, obscured at low level to hide the car parking, but letting in views of the sky and tree canopies from above. Irradiance was measured at a depth of 50 cm at the centre of the submerged rice canopies and pooled for both cultivars; measurements at 0 d were immediately after submergence. Our current understanding of the in-uence of tree canopies is based largely on one or two seasons' observations, which is not sucient for making reliable recommendations to farmers. No significant differences were found in the survival of seedlings that were labelled under conspecific canopies and those of a similar age that had survived from gorilla dung. Insect herbivores in the canopies of savannas and rainforests. The physical nature of solar radiation in heterogeneous canopies, spatial and temporal attributes. The 'saving' in soil evaporation at this site was about the same as the amount of water loss associated with the interception and re-evaporation of rainfall by the tree canopies. Towards this end, the current study sought to determine the effectiveness of seven artificial illumination sources for remote sensing measurements of healthy and nutritionally stressed plant canopies. The significance of crop canopies for nitrogen nutrition. Thus, it seems apparent that the use of highly reflective backgrounds may not overtly degrade the remote sensing images of plant canopies, as was initially expected. The station is covered by a series of elegant off-white canopies stretched taut between support beams resting on columns, giving the site an open, modern ambience. The potential annual primary production of closed canopies of unshaded coee seems to be 20+30 t ha71, equivalent to those of tea, oil palm and many tropical forest plantations. Thus, frugivorous birds are more likely to be found in the canopies of fleshy-fruited trees and are more likely to deposit seeds from fleshy-fruited lianas under these trees. Secondly, tree canopies provide a soil cover against erosive rainfall over a longer period than the cover provided by annual crops and thereby reduce nutrient losses due to erosion. Alternatively, the bees may prefer to forage on exposed leaves in fear of natural enemies or for ease of manoeuvrability at the periphery of tree canopies. In each block, we randomly selected three mopane trees with large canopies (8.3 m crown diameter) and another three with small canopies (2.7 m crown diameter). A range distance of 45 m was estimated from variograms, strongly suggesting that large tree canopies and gaps are the source of much of the spatial variance in throughfall volume. The levee vegetation has better development of foliar layers throughout all stages of the successional series, under canopies of different species sets, than does that of neighbouring swales. Regulation of germination under leaf canopies. Mammals of rain forest canopies. Tropical forest canopies: the last biotic frontier. The ecology of tropical rain forest canopies.

The platforms had canopies supported by beautiful ironwork, but overall the station fitted no conventional style. Long platform canopies supported by decorated iron and with wooden valances soon appeared. Each is clearly identified by its architecture, signage and entrance canopies. There are views over the green roof below and into the canopies of the surrounding trees. Tree canopies can also redirect water -ow along stems and branches, called stem -ow, which would enhance soil moisture close to their bases. Efficiency was therefore conserved, to a degree, while canopies reduced the solar energy they intercepted. Examples include heart valve leaflets, parachute canopies, thin airfoils (including bird, insect, or bat wings), sails, kites, flags, and weather vanes. Second, the intensity of the tungsten halogen lamps could be reduced in order to lower the thermal heating of plant canopies. Thus, all plants were measured under the seven lamps with their canopies aligned to face in the same direction. However, tomato plants had highly elongated and complex canopies that could not be easily measured from either a nadir or horizontal orientation. The distance primates transport seeds away from parent canopies, a result of their slow seed passage times and daily movement, may increase recruitment. Prior to conducting the remote sensing measurements of healthy and stressed pepper canopies, three energy measurements of the seven artificial light sources were completed. Our evolutionary ancestors spent much of their time navigating forest canopies. These examples are from corpora and from sources on the web.
