Coral Health and Restoration Challenges

The video tutorial discusses the major threats to coral reefs, including disease, high water temperatures, and ocean acidification. It explains coral bleaching and its effects on coral health. The video highlights the impact of coral diseases, such as white band disease and stony coral tissue loss disease, on coral populations. It also covers the efforts by organizations like Mote and NOAA to restore coral reefs through coral nurseries and research. The tutorial emphasizes the importance of understanding disease dynamics and promoting coral resilience.

What are the three major threats to coral reefs discussed in the lesson?

• Disease, high water temperatures, and ocean acidification

• Pollution, overfishing, and tourism

• Hurricanes, predators, and sedimentation

• Invasive species, algae blooms, and oil spills

What happens to corals when they expel the algae living within their tissues?

• They become more colorful

• They appear white or bleached

• They become immune to diseases

• They grow faster

How does stress affect corals in relation to diseases?

• It makes them more resistant to diseases

• It has no effect on their susceptibility to diseases

• It causes them to grow larger

• It makes them more susceptible to diseases

Which disease caused a significant decline in branching coral species like staghorn and Elkhorn in the late 70s and early 80s?

• Black band disease

• Stony coral tissue loss disease

• White band disease

• Coral bleaching

What is the estimated coral cover percentage of the Florida reef tract due to recent diseases?

• 50%

• 30%

• 10%

• 2%

What is the primary goal of the coral restoration mission in the Florida Keys?

• To introduce new coral species

• To increase tourism

• To eliminate all coral diseases

• To restore 25% stony coral cover

What is the role of raceways in coral restoration?

• They are used to monitor water quality

• They are tanks used to house and grow corals for research and out planting

• They are used for coral breeding

• They are used to transport corals to different locations

Which organization is collaborating with Mote to restore coral reefs in the Florida Keys?

• NOAA

• NASA

• EPA

• USGS

What is the focus of Mote's coral health and disease program?

• To increase coral growth rates

• To understand disease dynamics and promote coral health and resilience

• To study the effects of pollution on corals

• To develop new coral species

What is the significance of the selected restoration sites in the Florida Keys?

• They are the largest coral reefs in the world

• They represent a diversity of habitats and have a high probability of restoration success

• They are the most popular tourist destinations

• They are the least affected by coral diseases
