Pattern and paradox in parasite reproduction.

P Calow

    Parasitology
    |April 1, 1983
    PubMed
    Summary

    Parasites exhibit higher fecundity and adult longevity than free-living organisms, challenging traditional evolutionary explanations. A general life-cycle theory is applied to resolve these patterns and explore reproductive strategies in parasites.

    Area of Science:

    • Evolutionary Biology
    • Parasitology
    • Life-History Theory

    Background:

    • Parasites often display higher fecundity and adult longevity compared to their free-living counterparts.
    • Traditional explanations for parasite fecundity, focusing on transmission mortality, face neo-Darwinian challenges.
    • Observed patterns of increased fecundity and longevity in parasites contradict expected negative correlations.

    Purpose of the Study:

    • To investigate the evolutionary and life-history patterns of parasites.
    • To reconcile the paradoxes of increased parasite fecundity and longevity with general life-cycle theory.
    • To explore the influence of age-specific mortality and reproductive strategies in parasites.

    Main Methods:

    • Application of a general life-cycle theory to parasite biology.
    • Analysis of life-history traits, including fecundity, longevity, and reproductive investment.
    • Examination of age-specific mortality effects on life-cycle patterns.

    Main Results:

    • The general life-cycle theory provides a framework to understand parasite life-history paradoxes.
    • The theory addresses trade-offs between gamete size and number, and reproductive modes.
    • Parasite-specific data are integrated to validate theoretical predictions.

    Conclusions:

    • Life-cycle theory offers a robust explanation for elevated fecundity and longevity in parasites.
    • Understanding parasite life histories requires considering factors beyond simple transmission mortality.
    • The study highlights the importance of theoretical frameworks in parasite evolutionary biology.
