ANOVA was used to compare percent damage of all trees among topographic position, and linear regression analysis was used to examine how damage varied with the topographic site coefficient (Rebertus et al 1997). In the scientist research they had come to the conclusion that Basswood, American Elm, Sugar Maple, and Northern Red Oak were most susceptible. The least susceptible were Shagbark Hickory, Black Walnut, Easter Hophornbean and White Oak. Northern Red Oak and White Oak were almost resistant to the ice. It was more likely that trees in crown position would be undamaged. Trees that were on the lower slope were more likely to be damaged rather than trees in the upper slopes due to the position in the forest. .
John Bernard and his fellow researchers also studied the effects of an ice storm that happened in Western New York during March 3-4 of 1991, which deposited 2 cm or more of ice on 19,740 km squared radius (Bernard et al 1993). The researchers agreed with Rebertus and his fellow researchers that the effect of the storm deals with the angle of which the slope stands. Bernard and his researchers also gathered information that it also has to do with the elevation of the forest community, and the wind to determine the hardest hit counties. .
They compared Monroe and Ontario counties to determine the severity of the storm from upland and a lowland point of view. The researchers sampled three 10 x 50m plots in wooded hedgerow and one 10 x 50m plot on the edge of one of the mature forest stands ( Bernard et al 1993). Bernard and his fellow researchers determined that a tree that was tipped over would be classified 100% damaged (Bernard et al 1993). Finally they gathered information on 31 different tree species in 31 different quadrants, and measured diameters of approximately 940 standing trees and 1285 downed trees and limbs (Bernard et al 1993). .
Throughout their research they determined that the average percent damage to trees was 20%, the forests edge site along the forest field ecotone was the greatest damaged at 50% (Bernard et al 1993).
Sibilla Merian, a German naturalist, author, and illustrator was born in Germany. Frankfurt was a small town in Germany where she was raised. They had a wide family that were either an engraver and or a publisher. After the death of her stepfather that taught her much botony and engraving, she was l...
A seed certainly looks dead. It does not seem to move, to grow, nor do anything. In fact, even with biochemical tests for the metabolic processes we associate with life (respiration, etc.) the rate of these processes is so slow that it would be difficult to determine whether there really was anything alive in a seed. Seeds initially germinate when they absorb water, bursting the seed coat. Heat and light energy necessary for the process of germination. ...
