Question

use the information in the disappearance of the golden toad to answer the questions below.
1 how many golden toads could be observed during mating season when the toads population was thriving?
2 based on the golden toad populations habitat, why was extinction of the golden toad puzzling?
3 explain why it was significant that large numbers of other frogs and toads became extinct at the same time the golden toads disappeared.
4 explain what happens to cloud mist as the number of \dry days\ increases.
5 assuming the lifting cloud base hypothesis to be correct, which part of the monteverde cloud forest would likely be the least affected by the decrease in moisture? explain.
6 revisit investigative phenomenon relate this case to the investigative phenomenon: \how are changes in environmental conditions related to changes in population size?\ describe the sequence of events that could have led to the extinction of the golden toad, according to the lifting cloud base hypothesis.
21st century skills
find out more about other extinctions that occurred in the monteverde region during this time period. work in small groups to use the internet and other resources to learn more about what caused the extinctions you have been studying. each group should create a poster or presentation to share with the class.
the 21st century skills used in this activity include communication and collaboration, information literacy, and productivity and accountability.

Explanation:

1. Without the specific information from "The Disappearance of the Golden Toad", an exact number cannot be given. But typically, when a population is thriving, a relatively large number could be observed during mating - season.
2. The golden toad's habitat was a seemingly stable cloud - forest. Its extinction was puzzling because the habitat did not appear to have obvious and immediate threats like large - scale deforestation or major pollution events.
3. The extinction of multiple frog and toad species simultaneously indicates a broader environmental problem. It could be due to a shared environmental stressor like climate change, pollution, or a new pathogen affecting the entire amphibian community.
4. As the number of "dry days" increases, cloud mist likely decreases. Cloud mist is dependent on moisture in the air, and dry days mean less moisture available for the formation and sustenance of cloud mist.
5. If the Lifting Cloud Base Hypothesis is correct, the lower parts of the Monteverde cloud forest would likely be least affected. As the cloud base lifts due to decreased moisture, the lower levels would still have access to some remaining moisture and cloud - related humidity.
6. According to the Lifting Cloud Base Hypothesis, changes in environmental conditions (such as increased dry days and a lifting cloud base) led to decreased moisture in the golden toad's habitat. This reduction in moisture affected the toad's breeding, survival of tadpoles, and overall life - cycle, ultimately leading to extinction.

Answer:

1. Information from the source text is needed for an exact number.
2. The habitat seemed stable without obvious threats.
3. Indicates a broader environmental problem affecting amphibians.
4. Cloud mist likely decreases.
5. The lower parts of the Monteverde cloud forest, as they may still have some moisture.
6. Changes in environmental conditions led to decreased moisture in the habitat, affecting the toad's life - cycle and leading to extinction.
