Coral Biology and Climate Resilience

The video explains how corals adapt to changing environments through reproduction, particularly during the synchronized spawning event after October's full moon. Scientists collect coral sperm and eggs in laboratories to study and potentially breed new coral strains that can better withstand climate change. This research aims to restore life to the most affected parts of the reef.

What natural event triggers the great synchronized coral spawning?

• The first full moon in October

• The first full moon in April

• The summer solstice

• The winter equinox

How do scientists ensure they do not disturb the coral spawning process in the lab?

• By using blue light

• By using red light

• By using green light

• By using no light

How do ocean currents affect coral spawn?

• They change the spawn's color

• They increase the spawn's size

• They prevent the spawn from settling

• They help disperse the spawn

Why is the collection of coral spawn important for scientists?

• It provides samples for a year's worth of research

• It is a tourist attraction

• It helps in creating new coral reefs

• It is used for commercial purposes

What potential benefit do scientists see in different coral species breeding with each other?

• Increasing coral size

• Producing more resilient coral strains

• Decreasing coral growth rate

• Creating new coral colors

What is the ultimate goal of using selective breeding in corals?

• To increase the aesthetic value of corals

• To reduce the size of coral reefs

• To create corals that can withstand climate change

• To make corals more edible

What is the main challenge that corals face due to climate change?

• Increased water salinity

• Increased ocean currents

• Rising ocean temperatures

• Decreased sunlight
