  2. Annual Reproductive Potential, Diet, and Growth of the Map Turtle, Graptemys Geographica (Le Sueur)) in a Missouri Stream

    White, Donnell D.

    The annual reproductive potential, diet, and growth of the common map turtle (Graptemys geographica) was studied from April 1988 through June 1988 in the Niangua River, Dallas County, Missouri. The examination of reproductive tracts from 18 females indicate that two-thirds laid two clutches of eggs …

  3. The importance of female phenotype in determining reproductive potential and recruitment in Atlantic coast striped bass (Morone saxatilis)

    Peer, Adam Christopher2012

    The influence of female phenotype on the reproductive potential of Atlantic coast striped bass is addressed in three key areas of research. The importance of the environment in shaping maternal phenotype was evaluated using a spawning stock time-series to evaluate possible environmental drivers of …

  4. Differentiation in reproductive potential and chemical communication of reproductive status in workers and queens of the ant Myrmecia gulosa

    Dietemann, VincentUniversität Würzburg

    Division of reproductive labour in societies represents a topic of interest in evolutionary biology at least since Darwin. The puzzle of how helpers can be selected for, in spite of their reduced fertility has found an explanation in the kin selection theory: workers can overcome the cost of …

  7. Life history trade-offs in a parental care-providing fish: the role of reproductive value, predation threat, and physiological condition on brood abandonment decisions by paternal largemouth bass

    Zuckerman, ZacharyUniversity of Illinois at Urbana-Champaign2012

    Parental care evolved as a means to maximize reproductive success at a cost to physiological and nutritional condition of the care-providing individual, and at a cost to future reproductive potential. Parental investment decisions are rooted in tradeoffs between these factors, and when the cost of …
