A student decided to collect data to see if he could find support for the IDH in a grassland setting. His data generated the following averages; Low disturbance species richness average 51 ±.53 Intermediate disturbance species richness average 21 ±.61 High disturbance species richness average 31 ± .21 The student also conducted t-tests comparing the groups to each other and ended up with the following p values; Intermediate vs Low Disturbance p= .02 Intermediate vs High Disturbance p=.01 Examine the averages and p-values. Did the student find the pattern predicted by the IDH? Explain your answer.

The Jena experiment tested the effects of plant species richness on the ecosystem function of various grassland areas over a 15-year timespan. Ecosystem function was determined by measuring the biomass, soil characteristics, types, and numbers of producers and consumers in the area, and tested to determine the strength of the biodiversity effect on the ecosystem. The graphs show the ecosystem function at the onset of the experiment (dotted line) versus the ecosystem function at the end of the 15-year experiment (solid line) in four different test sites (A, B, C, and D).
1. Moose Management Area 6, WMU 350 In 1993–94, aerial counts of moose populations in Wildlife Management Unit 350 showed a density of 0.45 moose/km2 in the 5788 km2 area surveyed. What was the total population size (N)? 2. Another population count of Moose Management Area 6, WMU 350 occurred in 1997–98.This time, the population size was estimated at 3204 moose. What was the population density (Dp)? 3.Compare the two population sizes from the two counts of WMU 350 and determine the following variables. Show your work. ΔN: Growth rate: Per capita growth rate:
