Sample interview questions: What is your understanding of the impact of climate change on bird population dynamics and community stability?
Sample answer:
Climate Change Impacts on Bird Population Dynamics and Community Stability
Climate change profoundly affects bird populations and community stability through various mechanisms.
Changes in Distribution and Range:
- Rising temperatures shift climate zones, causing birds to adjust their breeding and wintering ranges.
- Some species may expand their ranges northward or into higher elevations, while others may contract their ranges.
Phenological Shifts:
- Warmer springs lead to earlier arrival dates, nesting, and breeding for many birds.
- Disruptions in the timing of food availability can impact nest success and survival.
Altered Habitat Quality:
- Climate change affects habitat structure and composition, which can impact bird abundance and diversity.
- Droughts, floods, wildfires, and sea-level rise can degrade or destroy critical habitats.
Physiological Impacts:
- Extreme heat events can cause heat stroke, dehydration, and increased mortality.
- Changes in precipitation patterns can affect water availability, which impacts drinking, bathing, and foraging.
Ecosystem Disruptions:
- Climate change alters… Read full answer
