D4.3.10 (HL)—Disruption of phenological synchrony Topic Practice
IB Biology syllabusBiology SL/HLFirst assessment 2025

Students practise interpreting real-world phenological mismatches—like Arctic plant–reindeer timing or great tit–caterpillar synchrony—to explain climate-driven ecological…

How this is tested

  • explain how mismatched timing between great tit breeding and caterpillar peak abundance reduces chick survival
  • link observed shifts in Arctic plant flowering and reindeer calving dates to reduced neonatal nutrition
