Temperature and Betula disribution on the Holy range Massachusetts1
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 densities were not significantly higher on the north face than on the south face of the mountain range. Eight separate t-
From this data analysis it was possible to determine that the results were due to chance, not congruent with my prediction. For Betula lutea, mean basal area (cm2 m-2) was higher on the north-facing slope (Fig 1), but was not significant (t = 1. 5 above ground) of each adult tree was recorded. For Betula lenta, the basal area (cm2 m-2) was significantly higher on the north versus the south face of the mountain range (t = 9. 2), but like Betula papyrifera, the mean density of Betula populifolia (ind ha-1) was marginally significant (t = 1. In fact, temperature is not the only factor that can determine the growth of Betula, or other species of trees. Within the 10x10m plots, the species and the dbh (diameter at breast height, measured at about 1. Mean basal area (cm2 m-2) of adult Betula species on Holyoke rangeFig 2. Also mean basal area (cm2 m-2) of birch trees found was significantly larger in only Betula lenta (Fig 1).
