Ecosystem Disruptions Case Studies Flashcards

1️⃣ Familiarise yourself with the flashcards:

  • Look through all the flashcards to see what’s on both sides.
  • Make sure you understand the information on each card. If something’s unclear, click the link to the revision notes at the bottom of the page for more details.

2️⃣ Test yourself:

  • Look at the question or prompt on each card and try to remember the answer before flipping it over.
  • Check the answer and make a note of any cards you find challenging and need to go over more.

3️⃣ Consistently Review and Practice:

  • Use spaced repetition: spend more time on the cards you struggle with and go over them more often.
  • Regularly review all the flashcards to help you better understand and retain the information over time.

Note: We may include questions that have multiple correct answers. It’s useful to remember specific examples to understand these concepts better.

What is Ash Dieback, and how does it affect UK woodlands?

Ash Dieback is a fungal disease originating in Asia that threatens 80% of the UK’s ash trees. It affects many species that rely on ash trees, causing severe knock-on effects on the ecosystem.

What are the potential consequences if 80% of the UK’s ash trees are affected by Ash Dieback?

If 80% of ash trees are affected, insect populations that rely on these trees will decrease, leading to a decline in birds and mammals that feed on these insects. This, in turn, affects birds of prey that feed on these mammals and birds.

How did the Burmese Python become an invasive species in the Florida Everglades?

Burmese Pythons were smuggled into the US and sold as pets. Unable to care for them, owners released them into the Everglades, where they thrived due to the abundant food supply.

What impact have Burmese Pythons had on the Everglades ecosystem?

Burmese Pythons have caused a significant decline in mammal populations and have disrupted the food web, leading to increased populations of primary consumers like insects.

How are people trying to control the Burmese Python population in the Everglades?

Everglades park rangers encourage tourists to report python sightings, and hunters are encouraged to kill the snakes to curb their growing population.

What do these case studies of Ash Dieback and Burmese Pythons illustrate about ecosystems?

These case studies show the delicate balance of ecosystems and how both human involvement and natural events can lead to dramatic changes and disruptions in these systems.
