本文研究了土拨鼠在自然种群和围栏中的竞争行为。自然种群的攻击互作率与密度和季节有关。互动率，互动距离，和创伤都表明在夏季和初秋的侵略性水平下降，即使在植被的夜晚是恒定的情况下。笔遭遇的特点是相当多的战斗比场互动。被动回避下属是最常见的类型的竞争性互动中观察到的领域。
Agonistic behavior of woodchucks was studied in natural populations and in pens. Aggressive interaction rate in natural populations was correlated with density and season. Interaction rate, interaction distance, and wounding all indicated decreasing levels of aggressiveness during the summer and early fall even in situations where vegetation night was constant. Pen encounters were characterized by considerably more fighting than were field interactions. Passive avoidance by subordinates was the commonest type of agonistic interaction observed in the field.
