Compensation for a bad start: grow now, pay later?
Trends in Ecology & Evolution
|April 13, 2001
Summary
Nutritional deficits during development can lead to compensatory growth when conditions improve. However, this accelerated growth may incur hidden, long-term costs impacting adult life history.
Area of Science:
- Developmental biology
- Ecology
- Evolutionary biology
Background:
- Early-life nutrition significantly shapes an organism's development and life trajectory.
- Nutritional deficits during critical developmental periods can be followed by accelerated growth if conditions improve.
Purpose of the Study:
- To explore the long-term costs associated with compensatory growth following early-life nutritional deficits.
- To highlight the underappreciated role of these costs in ecological and evolutionary contexts.
Main Methods:
- This study is a review and synthesis of recent research findings.
- It analyzes the implications of compensatory growth from an ecological and evolutionary perspective.
Main Results:
- Compensatory growth, while seemingly beneficial for recovery, is linked to various delayed costs.
- These costs manifest later in adult life and are often not immediately apparent.
Conclusions:
- The long-term consequences of compensatory growth require further investigation.
- Understanding these costs is crucial for a comprehensive view of developmental plasticity and life-history strategies.
