Ecology 6th Edition by Charles Krebs

تمرين 3

The longest experiment in ecology is the Park Crass Experiment begun in 1856 at Rothamsted, England. A mowed pasture was divided intO₂0 plots, and a series of plots were fertilized annually with a variety of nutrients, including nitrogen. Discuss the predictions you would make regarding biodiversity on fertilized and unfertilized plots for this experiment, using the six factors discussed in this chapter. Silvertown et al. (2006) give the observed results.
