Study Snapshot
Key takeawaySongbird populations exhibit local adaptation in reproductive timing by relying on differential critical photoperiod response, which is predictive of future breeding ground conditions.
PopulationOlder adults (50-71 years)
Sample size24
MethodsObservational
OutcomesBody Mass Index projections
ResultsSocial networks mitigate obesity in older groups.
