Phenology and Its Ecological Impacts

The video explains phenology, the study of seasonal biological events, and its historical importance. It highlights how climate change is altering natural rhythms, affecting plants, animals, and even human activities like tourism. The video emphasizes the need for awareness and action to mitigate climate change impacts.

What is phenology primarily concerned with?

• The chemical composition of plants

• The timing of biological events in relation to seasons

• The study of animal behavior

• The migration patterns of birds

What does the Greek word 'pheno' mean?

• To hide

• To study

• To show or appear

• To grow

How has global warming affected the timing of bud burst?

• It has delayed bud burst by several weeks

• It makes bud burst unpredictable

• It has no effect on bud burst

• It causes bud burst to occur earlier

What adaptation have winter moth caterpillars made in response to earlier bud burst?

• They have migrated to a different region

• They now hatch earlier

• They have changed their diet

• They have started hatching later

What is the impact of earlier bud burst on pied flycatcher birds?

• Their population has increased

• They have found new food sources

• Their population has decreased

• They have started migrating earlier

How have earlier bloom times affected the Cherry Blossom Festival in Washington D.C.?

• The blossoms last longer than before

• The festival has been moved to a different location

• The blossoms fade earlier, disappointing tourists

• The festival has been canceled

What is a potential economic impact of phenological changes?

• Lower transportation costs

• Increased agricultural yields

• Decreased tourism revenue

• Higher energy costs

What is a key factor causing plants to bloom earlier?

• Higher temperatures

• Increased rainfall

• Longer daylight hours

• Stronger winds

What is the broader implication of phenological changes on ecosystems?

• They improve biodiversity

• They have no significant impact

• They stabilize climate patterns

• They can disrupt food webs

What can individuals do to help address the issues caused by phenological changes?

• Ignore the changes

• Contribute to slowing climate change

• Encourage earlier blooming

• Support deforestation
