Chapter 55.5, Problem 3SB
Summary Introduction
To review:
Single large nature preserves or several small preserves would experience greater edge effects.
Introduction:
The edge effect is an ecological concept that describes the overlapping regions between two ecosystems like water and land that are rich in species and biodiversity. The edge effect is explained by the species area relationships. The number of species in a given area depends upon the total measure of that area. The scientists predicted that the larger is the geographical area, more is the number of species.

In eastern Ohio, most climax communities are forest, defined as having a closed canopy
(75%-100% cover) allowing very little light to penetrate to the ground.2 By the end of the
study in 2000, is it likely that this old field site (at 40°N) had reached the relative stability of a
climax community? (the study began in 1950)
A. No. Most forest communities take at least 100 years to reach 75% cover.
B. No. According to the graphs, the old field will be at ~50% coverage after 50 years.
C. Yes. Unless the area has been disturbed again, it should stay stable after 10% cover.
D. Yes. At 40° latitude, over 50% of the old fields were above the stability line on the graph.

- Briefly describe some of the long-term ecological research conducted at Hubbard Brook Experimental Forest.arrow_forwardWhat is the relationship between a pioneer species and primary succession? A pioneer species is an invasive species that causes areas to experience primary succession. There is not a relationship between a pioneer species and primary succession. The pioneer species only occurs in areas of secondary succession. A pioneer species is important in an area of primary succession because it can grow and thrive in areas where most other species cannot. A pioneer species only inhabits areas of primary succession.arrow_forwardWilderness preserves are relatively clear and immediate ways of protecting endangered species and ecosystems.

Several years later, the area is covered with a mix of grasses, shrubs, and small trees. The process of ecological recovery in this forest is characterized by the re-establishment of complex plant communities. 1) Is this an example of primary or secondary succession? 2) Which stage of ecological succession is most likely represented by this scenario? Intermediate stage Alternative stable stage Pioneer stage Climax Community Stagearrow_forward7) Describe how the types of vegetation present on this farmland would change if a fire burned down all the trees 120 years after the land was abandoned.arrow_forward
