What was the hypothesis of the Hubbard Brook experiment?
One of their specific hypotheses was that cutting down trees would lead to increased streamflow and corresponding increases in downstream reservoirs. At the same time, cooperating ecosystem scientists were interested in studying how entire watersheds respond to major disturbances.
What did the Hubbard Brook watershed study show scientists?
Hubbard Brook scientists pioneered the small watershed approach to understanding forest ecosystems and advanced the use of whole-ecosystem manipulations to quantify the response of forests to disturbance.
What conclusion did the scientists make from the results of the Hubbard Brook experiment?
In the Hubbard Brooke experiment; scientists cut down forest for watershed and measured the effect on stream output: What results supported their conclusion that active vegetation can immobilize Nat the watershed: Stream nitrogen concentration increased in experimental plot compared to control B.
Why was the Hubbard Brook Experimental Forest important?
“Over the past 50 years, Hubbard Brook Experimental Forest has provided an ideal setting for major research on water yield, water quality, and the effects of acid rain; these studies have gained us a fundamental understanding of forest and aquatic ecosystems.”
Which is the most significant finding of the Hubbard Brook experiment?
Which is the most significant finding of the Hubbard Brook experiment? In an ecosystem, matter is constantly being recycled. In contrast, such as that from the Sun, is never recycled.
What does the Hubbard Brook study teach us?
Researchers using the Hubbard Brook was able to determine that when trees are no longer there to take up the soil nitrate, it leaches out of the soil and ends up in the stream which drains into the watershed.
When studying Hubbard Brook What did scientists discover or confirm about the impacts of deforestation?
When studying Hubbard Brook, what did scientists discover or confirm about the impact of deforestation? Researchers were able to confirm that as forests and grasslands grow, large amounts of nutrients accumulate in the vegetation and in the soil.
What ecological lesson did you learn from the controlled experiment on the clearing of forests as described in Hubbard Brook experiment?
What ecological lesson can we learn from the controlled experiment on the clearing of forest described in the Core Case Study that opened this chapter? Vegetation controls water and nutrient loss from ecosystems. Loss of vegetation diminishes the systems’ ability to retain nutrients and water.
In which portion of the country is Hubbard Brook Experimental Forest?
The Hubbard Brook Experimental Forest (HBEF) is located in the southern part of the White Mountain National Forest (WMNF) in central New Hampshire (Figure 1). The HBEF is characteristic of much of the White Mountain National Forest (Fahey et al.
How was the total number of birds at the Hubbard Brook Experimental forest changed over time?
At Hubbard Brook, bird abundance is down from its peak in the early 1970s but the drop occurred largely due to changes in bird species composition associated with forest aging.
Why did scientists have to include land outside of the Yellowstone ecosystem?
Why did scientists have to include land outside of Yellowstone National Park in the plan for managing the Yellowstone ecosystem? The reason is because organisms that lived inside the park would also spend time outside the park and open up the ecosystem. You just studied 11 terms!
What ecological lesson can be gained from the experiment on the clearing of forests described in the case study that opened the chapter?
1. What ecological lesson can we learn from the controlled experiment on the clearing of forest described in the Core Case Study that opened this chapter? Vegetation controls water and nutrient loss from ecosystems. Loss of vegetation diminishes the systems’ ability to retain nutrients and water.
