摘要通过分析粪便样本，对来自佛罗里达州东北部的81只小菜龟(Malaclemys Terrapin Centata)的食性进行了评价。雌性饲料与雄性饲料有显著不同(p<；0.01)；雌性的粪便样本按出现的顺序依次为螃蟹、沼泽环纹扇贝(Littorina Irrorata)和矮小扇贝(Mulinia Lateralis)，而雄性的粪便样本依次为矮小的扇贝和螃蟹。我们认为，头部大小的二形性对雌性在筑巢攻击期间经历猎物可获得性转变是有利的。
Abstract We evaluated the diets of 81 Carolina diamondback terrapins (Malaclemys terrapin centrata) from northeastern Florida by analyzing fecal samples. Female diets were significantly different from male diets (p < 0.01); fecal samples from females contained crabs, marsh periwinkles (Littorina irrorata), and dwarf surf clams (Mulinia lateralis) in that order of occurrence, whereas fecal samples from males had dwarf surf clams and crabs in that order. We suggest that head-size dimorphism is advantageous to females during nesting forays when they experience a shift in prey availability.
