Study Notes
Enzyme Function and Reaction Acceleration
- Enzymes increase reaction rates by binding to and stabilizing the transition state.
- This stabilization lowers the activation energy required for the reaction.
Algal Growth Predictions
- Adding nitrate leads to a midway increase in algal growth that stabilizes horizontally.
Cicada Emergence Timing
- Reduced cottonwood ground cover correlates with cicadas emerging approximately 10 days earlier.
Wildfire Effects on Cicadas
- Wildfires reduce ground cover, increasing soil temperatures and resulting in earlier cicada emergence.
Cottonwood Growth and Food Web Impact
- Enhanced cottonwood growth supplies more resources for cicadas, potentially boosting the kestrel population.
Honeybee Communication
- Honeybees use waggle dances to convey flower patch locations; longer dances indicate flowers are farther away.
Grunion Spawning Evidence
- Grunion spawn aligned with highest nighttime tides, occurring every two weeks during the spawning season.
Animal Survival and Food Scarcity
- Data imply animals spending 3-5 days in ARD (animal recovery duration) have better survival rates during food scarcity compared to those in ARD for 13-15 days.
