Both the quality and spatial configuration of a habitat can affect the distribution of its inhabitants. However, few studies have directly compared the relative effects of the two. In this paper, we focus on spatial patterns in the distribution of an oak-specific moth, Tischeria ekebladella. At the landscape level, the species was more often present on well-connected trees than on isolated tree...

Leaf area density is a biologically appealing index of forest tree health because it can provide an assessment of foliage loss or retention; however, it is difficult to measure directly. In contrast, the ratio of crown length to sapwood area (CL:SA) is quite amenable to objective field measurement, and could be interpreted as an index of crown sparseness. CL:SA was computed for Douglas-fir tree...

Supplemental irrigation under prolonged drought conditions has a key role in providing water for transpiration of rain-fed fig trees. The effect of different times and amounts of supplemental irrigation at different distances from the tree trunk on quantity and quality of Estahban rain-fed fig production was evaluated during two years. A randomized complete block design with four replications o...

Prohexadione-calcium (Pro-Ca) is a recently developed plant growth retardant used in some fruit trees. However, it important that the reduction of vegetative shoot dose not decrease yield and quality. In this study, effects Pro-Ca applications on quality Monroe peach, growing vigor rootstock (GF 677) were investigated. For reason, trees sprayed twice with 0 (water + surfactant), 62.5, 125, 250 ...

Lossless compression is a new technique for reduction of data quantity without reducing the quality of an image. The storage and transfer of compressed data is faster as compared to uncompressed data. To achieve high compression ratio and compression time, we use modified Embedded Zero Tree Wavelet (EZW), improved Enhanced Set-Partitioning In Hierarchical trees (ESPIHT) techniques. These techni...

Anecdotal evidence gathered from pruning crew observations indicates that there may be enhanced branch growth at the new crown base in young pruned coastal Douglas-fir (Pseudotsuga menziesii var. menziesii) trees compared to unpruned trees. This has the potential to reduce the quality and value of the stem above the pruned portion of the bole. An analysis of the size of branches in the remainin...
