Accumulating evidence in ecology: Once is not enough

Area of Science:

• Ecological science
• Environmental modeling
• Scientific methodology

Background:

• Many ecological studies are treated as isolated investigations.
• The "reproducibility crisis" highlights limitations of single-study findings.
• Scientific progress relies on comparing hypothesis-driven predictions with observations.

Purpose of the Study:

• To advocate for a systematic approach to accumulating ecological knowledge.
• To demonstrate the benefits of sequential study design over ad hoc methods.
• To discuss implications for designing future ecological research.

Main Methods:

• Comparing hypothesis-based predictions from ecological models with empirical observations.
• Analyzing the iterative process of model-observation comparison.
• Evaluating different knowledge accumulation strategies (ad hoc, meta-analysis, systematic).

Main Results:

• Repeating the model-prediction-observation cycle builds confidence in models and hypotheses.
• A systematic, information-state-driven approach accelerates learning in ecology.
• Existing data collection programs can be adapted for this systematic approach.

Conclusions:

• A systematic approach to study design significantly increases the rate of learning in ecology.
• This method enhances confidence in the generated ecological knowledge.
• Expanded use of systematic study sequencing is recommended for ecological research.
