Temperature and Betula disribution on the Holy range Massachusetts1 essays Temperature and Betula distribution on the Holyoke Range, Massachusetts In this study, it will be tested whether temperature affects tree densities in the genus Betula on different slopes of the Holyoke Range, specifically the north and south faces of the mountain range. My prediction is that the north face of the mountain will have a higher density of these trees than the south face of the range because of the temperature differences of the north slope being warmer than south slope for the range of growth for these trees. This experiment can be used to predict patterns of vegetation in other similar latitudes and slopes around the world. On September 20, 2000, the birch tree genus, Betula, density was measured on the north face of the Holyoke Range and on September 27, 2000, Betula ¡s density was also measured, but on the south face of the Holyoke Range. There were eight sites laid across a 150m transect line running across the slope starting from a subjectively chosen point. Based on the data collected on the Holyoke Range, the birch trees densi ties were not significantly higher on the north face than on the south face of the mountain range. Eight separate t-tests were performed, four on the density of the adult birch trees, and another four on the basal density of adult birch trees. From this data analysis it was possible to determine that the results were due to chance, not congruent with my prediction. From the results of my data, it can be concluded that temperature is not a factor in the tree density of Betula. In fact, temperature is not the only factor that can determine the growth of Betula, or other species of trees. Certain biotic and abiotic factors that can explain vegetation patterns of similar areas compared to this study. In this study, it will be tested whether temperature is one of the factors that affect tree densities in the genus Betula on different slopes of the Holyoke Range, specifically the north and ...
