Notably, the impact of increasing cohort N on T max is attenuated logarithmically (ln N) . Historically, this region was only sparsely populated and human alteration of the environment was limited. Ecosystems in the Southeastern U.S. Are Vulnerable to Climate Change - USGS Based on our analysis of 14 year (i.e., 2002-2015) Stage IV precipitation data, the impact of the Edwards Plateau on the spatial distribution of precipitation is most prominent in August (Figure 1b), probably due to strong radiative heating and fewer disturbances by strong synoptic scale transient . Handbook of Texas Online, but the DOI has constant concern regarding the impact of such a decision due to the vast number of areas this species inhabits. This provided an ideal place for antelope.
