通过对雄性近岸蟹Carcinus maenas(L.)之间的打斗，研究了资源价值变化对竞争行为的影响。在有没有食物的情况下。描述了Macinus maenas的激动性行为的本质。赢家和输家的行为似乎与战斗的早期阶段不同。比赛不是从最初的展示开始，然后是强度的逐渐增加。比赛一开始，比赛就变得非常激烈，表演表演贯穿整个比赛。不出所料，与食物的竞争似乎愈演愈烈。战斗的持续时间是高度可变的，但在有食物的情况下，比赛的持续时间显著低于没有食物的比赛(平均战斗时间分别为559±S.E.53秒和1143±S.E.135秒)。结合目前博弈论模型的预测结果进行了讨论。
The effects of altering resource value on agonistic behaviour were investigated by staging fights between pairs of male shore crabs, Carcinus maenas (L.) in the presence and absence of food. The nature of the agonistic behaviour of Carcinus maenas is described. The behaviour of winners and losers appears to be different from an early stage in the fights. Contests do not begin with initial display followed by a progressive increase in intensity. The fights become very intense almost immediately at the start of a bout and display acts are performed throughout the fights. As expected, there appears to be an increase in intensity in the contests with food. The duration of fights is highly variable but is significantly lower for contests when food is present than in contests without food (mean fight length 559 ± S.E. 53 and 1143 ± S.E. 135 seconds respectively). The results are discussed in relation to current predictions from game theory models.
