项目摘要

Factors governing the occurrence of unique territorial behavior termed barricade building by the brachyuran crab Ilyoplax pusilla (family Dotilllidae) living on tidal flat, have been explored for the following aspects.1.Influence of external factors on frequency of barricade buildingThe frequency of barricade building increased in the breeding season, but was not correlated with the tidal regime. The frequency was also not related with the population density or with difference of the substratum condition.2.Relationship of barricade building with mating successComparison of occurrence of barricade building between pairing males and non-pairing males revealed that the former made barricade building more frequently than the latter. This finding suggests that barricade functions advantageously for pair formation.3.Interspecific comparison of earthen-structure avoiding tendencyComparison of response to artificial earthen structure between Ilyoplax pusilla and other two dotillid species with … More out barricade building behavior, revealed that I.pusilla less frequently broke the structure or avoided it more frequently than the other two species.4.Model constructionIn one model, three strategies each for barricader (build, do not build, build to smaller) and barricadee (destroy, do not destroy, destroy to smaller) are assigned, and the evolutionary dynamics of their frequency has been investigated. The model shows that cost by barricade should be frequency dependent to explain why only part of population members build barricades. However, the equilibrium is only neutrally stable and random genetic drift should turn the system with no barricade. Introduction of frequency depended strategy, destroy barricade depending on their frequency, made the equilibrium with intermediate barricade frequency stable. In the other model, life history strategies have been investigated by dynamic programming method. In ESS, barricade is built only in the breeding season, which coincides with field data Less

已经探索了以下方面探索了涉及养在潮汐平坦的北方野鸡蟹（Brachyuran Crab Ilyoplax pusilla（家庭dotillidae））所谓的独特领土行为的因素。该频率也与人口密度或底层条件的差异无关。2。障碍物建筑物与交配成功相比的关联构建与后者相比，与后者更频繁地建立了障碍物的障碍物相比。这一发现表明，路障在配对形成方面具有优势。3。避免倾向的倾斜结构比较，避免了对人造泥土结构的趋势与伊利诺普拉克斯·帕西拉（Ilyoplax Pusilla）和其他两个多质体物种之间的反应相比，并且与……更多的屏障建筑物行为相比，i.pusilla更加频繁地避免了这种策略。（构建，不要构建，构建到较小）和barricadee（销毁，不要销毁，销毁到较小），并研究了其频率的进化动力。该模型表明，通过路障的成本应依赖于频率，以解释为什么只有一部分人口成员建立路障。但是，相等的brium仅是中性稳定的，随机遗传漂移应在没有障碍物的情况下转动系统。引入频率依赖性策略，根据其频率破坏路障，使等效brium具有中间路障频率稳定。在另一种模型中，通过动态编程方法研究了生活历史策略。在ESS中，路障仅在繁殖季节建造，该季节与现场数据一致
