Chapter 55, Problem 2Q
Summary Introduction
To analyze:
The trends observed from the given graph; the trend that has been observed over time in the bee pollination date and in mean April temperature; the reason due to which the two trends moved in opposite directions and the significance of the difference in slope of the entire time period
versus the shorter time period, after 1970.
Given:
The scatter plots of the distribution, for the dates that are predicted for pollination by individual bee species, has been plotted in the top graph (between the years 1870–2010) and for the mean April air temperature (1900–2010) has been plotted in the bottom graph.
Introduction:
The scientists took 10 bee species and observed their pollination trends across North America. The trends between the pollination time by individual bee species and the flowering of plants during spring season was observed. These trends were also correlated with the mean air temperature of April (spring season occurs in North America during the April month). All these trends were observed for about 13 years.

What is the trend in the data during the first 12 years of the periodshown? Draw a line through the first 12 data points that best representsthis trend.
The warming trends discussed in the Case Study are most pronounced at the equator, where sunlight is most direct. What would you predict the effect of global warming to be nearer the poles, where temperatures are lower and there is less sunlight?
Look at the following temperature and precipitation graph for a city around the world. Using this information, write down which biome each city has in it. Be careful to read the numbers along The numbers along the Y-axis carefully. For precipitation, you will need to look at figure 2.2, which has annual precipitation numbers in centimeters. Then compare them to the monthly precipitation numbers in the graph, which are in millimeters. It may be helpful to add up The graph numbers and convert that number to centimeters in order to determine the Biome. Average temperatures are also represented on figure 2.2.
