From 1997 to 1999, we characterized red-cockaded woodpecker (Picoides borealis) behavior in a loblolly (Pinus taeda) and shortleaf (P. echinata) pine forest in Mississippi. We recorded stem type and size class used, foraging location, height, first behavior type observed and cumulative behaviors during 5-hour visual observation periods of 41 red-cockaded woodpecker groups. Overall, 94% of all s...

Advances made recently in the study of plant growth substances and their function in normal growth have raised the question of their possible role in atypical and pathological growth and specifically in the gall development induced by Phytomonas tumefaciens (Smith and Town.) Bergey et al. A suggestion of their presence was first given by the marked epinasty of leaf petioles in plants inoculated...

BACKGROUND & OBJECTIVES To evaluate the retention of complete cast crowns in teeth with adequate and inadequate crown height and to evaluate the effects of auxiliary retentive features on retention form complete cast crowns. MATERIALS AND METHODS Sixty freshly extracted human premolars. They were divided into 2 major groups depending upon the height of the teeth after the preparation. Group1 ...

Communities dominated by Baccharis pilularis (coyote brush) are expanding in coastal California, altering fuel load on a landscape scale, yet there is no standard method for estimating biomass in this vegetation type. In an attempt to develop a non-destructive field method for estimating biomass in Baccharisdominated communities, we compared three indirect measures including crown canopy height...

the asiatic hybrid lily, a bulbous ornamental plant, has a special position in the horticulture as cut flower. to overcome some problems in nutrition of bulb flowers, the use of hydroponic system and nutrient solution is important in the cultivation of these flowers. the asiatic hybrid lilium bulbs “tresor” cultivar, used for the current research were planted under 3 different calcium levels in...

The accuracy of height predictions at various ages based on five different methods (Tanner-Whitehouse mark I; Tanner-Whitehouse mark II; index of potential height; Bayley-Pinneau; Roche-Wainer-Thissen) was compared at yearly intervals with final height achieved in 32 boys (78 predictions) and 100 girls (227 predictions) with constitutionally tall stature. The boys were initially seen at a mean ...

The tissue culture derived sugarcane var. CoJ 64 plants attained better height, millable cane height and a greater number of live buds to conventionally raised plants. Further, the plants raised in vitro showed 13.2% increase in cane yield and 11.03% sugar recovery as compared to conventionally propagated sugarcane under parallel agronomic practices in the field, advocating suitability of seed ...

 Knowledge of the Saxaul dimensions used in sand dunes stabilization is considered essential for designing live windbreak in desert regions. This research aimed to collect and analysis data and was performed on the pruned and control shrubs of Haloxylon aphyllum L. in Yazd province, Iran in the last two decades. Our review clearly showed the superiority of shrubs pruned at the height of 35 cm i...
