    Summary
    This summary is machine-generated.

    Wild-caught rats, like domesticated ones, adjust feeding behavior based on food costs. However, wild rats require more training and are less efficient in laboratory settings.

    Area of Science:

    • Animal behavior
    • Behavioral ecology
    • Domestication studies

    Background:

    • The impact of domestication on animal behavior is not fully understood.
    • Generalizations from domesticated to wild animals require caution.
    • Previous studies show domesticated animals adjust meal size and frequency with food costs.

    Purpose of the Study:

    • To investigate if wild-caught rats exhibit similar feeding behavior changes as domesticated rats when food procurement costs vary.
    • To assess the trainability and efficiency of wild-caught rats in a laboratory setting.

    Main Methods:

    • Wild-caught rats were subjected to laboratory free-feeding studies.
    • Changes in the cost of accessing food were manipulated.
    • Feeding patterns (meal frequency and size) were recorded and analyzed.

    Main Results:

    • Wild-caught rats demonstrated a behavioral response to increased food procurement costs, mirroring domesticated rats.
    • Wild-caught rats required longer training periods compared to domesticated rats.
    • Efficiency in the laboratory setting was lower for wild-caught rats than for domesticated counterparts.

    Conclusions:

    • Laboratory feeding studies can effectively simulate foraging parameters relevant to natural environments.
    • Wild-caught animals show behavioral plasticity in response to economic principles of foraging.
    • Differences in training and efficiency highlight the influence of domestication on laboratory behavior.
