Why is sand temperature crucial for marine iguana nesting sites?

• It determines the speed of egg incubation.

• It affects the gender of the offspring.

• It influences the size of the nest.

• It determines the survival rate of algae in the area.

How do marine iguanas typically assess potential nesting sites?

• By tasting the sand for nutrient content

• By digging trial nests

• By observing the behavior of other iguanas

• By measuring the sand temperature with their bodies

What role does the proximity to the shoreline play in marine iguana nesting site selection?

• Closer proximity increases the risk of egg flooding.

• Closer proximity provides easier access to food.

• Closer proximity ensures a warmer nesting environment.

• Closer proximity reduces the risk of predation.

Which of the following is NOT a factor in marine iguana nesting site selection?

• Sand grain size

• Nesting site elevation

• Social status within the iguana community

• Vegetation cover

How does vegetation cover affect marine iguana nesting sites?

• It provides necessary nutrients for the eggs.

• It offers shade, affecting sand temperature.

• It attracts predators, increasing risk.

• It has no significant effect.

What is the significance of nesting site elevation for marine iguanas?

• Higher elevations have cooler temperatures, which is preferred.

• Lower elevations are closer to food sources.

• Higher elevations reduce the risk of flooding.

• Lower elevations have softer sand, making it easier to dig nests.

How does the risk of predation influence marine iguana nesting site selection?

• Sites with higher predation risk are preferred due to less competition.

• Sites with lower predation risk are preferred to increase offspring survival.

• Predation risk is not a significant factor in site selection.

• Sites with moderate predation risk are preferred for their biodiversity.

In what way does the availability of food sources around nesting sites impact marine iguana behavior?

• It determines the size of the nesting colony.

• It influences the timing of nesting.

• It affects the depth at which iguanas lay their eggs.

• It has no impact on nesting behavior, only on feeding behavior.

What is the impact of sand grain size on marine iguana nesting sites?

• Coarser sand allows for better drainage and is preferred.

• Finer sand retains heat better and is preferred.

• Sand grain size has no impact on nesting site selection.

• Coarser sand is harder to dig and is therefore avoided.
