Answer:
Plants and animals have life events that seemingly occur like clockwork every year. Birds can migrate, mammals may hibernate, flowers bloom, and leaves change colors. The study of how the biological world times these natural events is called phenology. Scientists now understand that plants and animals take their cues from their local climate (long-term weather patterns). Climate is impacted by non-biological factors—temperature, precipitation, and available sunlight. Species use the predictable yearly changes in the climate to determine when they start natural events such as breeding or flowering.
Climate change is slowly increasing average annual temperatures. One of the most noticeable ways that climate change is impacting wildlife is by disrupting the timing of natural events. With warmer temperatures, flowering plants are blooming earlier in the year and migratory birds are returning from their wintering grounds earlier in the spring. Phenology is an important subject for conservationists to study because it helps us understand the patterns of specific species and overall ecosystem health. Every species has an impact on those in its food chain and community, and the timing of one species' phenological events can be very important to the survival of another species.
