摘要本研究观察了大小匹配的I型与I型，II型与II型，以及I型与II型雄性之间的竞争互动和竞争，以建立苏氏原螯虾（乔克托瓦奇小龙虾）的基线优势秩序和行为动力学。三种类型的启动行为，或攻击，观察在每个互动：矛盾的接触，爪提高，和弓步。还进行了喂食竞争研究，以评估竞争相互作用和喂食比赛的获胜者之间的关系。只有I型与I型比赛显示出随着时间的推移观察到的互动数量下降，但在30分钟的记录期间，所有三种类型的行为的每一个人的竞争互动的持续时间下降。成功者和失败者并没有像其他研究中那样优先使用相同的启动行为。以前的研究也记录了I型主导II型男性，但在本研究中I型男性并不主导II型男性。竞争性比赛的获胜者赢得了显着更多的喂养比赛。目前的研究结果表明，行为动力学和形式优势可能是物种特异性的，仔细考虑的大小差异是必要的，以检查形式优势。
Abstract This study observed agonistic interactions and contests between size-matched form I vs. form I, form II vs. form II, and form I vs. form II males to establish baseline dominance orders and behavioral dynamics for Procambarus suttkusi (Choctawhatchee Crayfish). Three types of initiation behaviors, or attacks, were observed during each interaction: ambivalent contact, claw raise, and lunge. Feeding competition studies were also performed to assess the relationship between the winners of the agonistic interactions and feeding contests. Only form I vs. form I contests showed a decline in the number of interactions observed over time, but the duration of each individual agonistic interaction declined for all three types of behaviors during the thirty-minute recording period. Winners and losers did not preferentially use the same initiation behaviors as used in other studies. Previous studies also documented form I dominating form II males, but form I males did not dominate form II males in the present study. Winners of the agonistic contests won significantly more feeding contests. The results of the current study suggested that behavioral dynamics and form dominance may be species specific and that careful consideration of size differences are necessary in order to examine form dominance.
