项目摘要

(1) Male Uca arcuata courted by approaches from their burrows and by wandering. Difference in the rate of encounter with females between burrow-holding males and burrow-less wandering males was not significant. Burrow-holding males less often caused displacement of females for wandering than wandering males did. Burrow-holding males behaved not to reduce availability of potential mates in their neighborhood.Burrow dwelling males were apt to initiate wandering after decreased encounters with females. Wandering of females enticed by wandering males occurred as often as wandering of males caused by other males. Most wandering males that displaced burrow owners used the burrows one or more times after displacing the owners. Wandering males experienced more interactions with other males than burrow-holding males did. Courting during wandering had the extra cost of fighting for temporal burrows, and there was not increase of the encounter rate of females during wandering.(2) Mating exclusively occurred during holding burrows, but the rate per a fixed number of encounters with females was not different between burrow-holding males and wandering males.(3) The behavior pattern of courtship of this species was compared with other species of fiddlers. Courtship during wandering increased in relation to the environmental condition of burrowing habitat. Highly successful underground mating abruptly decreased courting by wanderers.

(1)雄性弧形Uca通过洞穴接近和四处游荡求偶。保持洞穴的雄性和没有洞穴的游荡的雄性在遇到雌性的比率上没有显著差异。与游荡的雄性相比，留在洞穴中的雄性较少因流浪而导致雌性移位。居住在洞穴中的雄性在行为上不会减少其周围潜在配偶的可获得性。居住在洞穴中的雄性在与雌性接触减少后容易开始走动。在流浪雄性的引诱下，雌性游荡与其他雄性引起的雄性游荡一样频繁。大多数流浪的雄鸟在迁徙洞穴主人后，都会使用洞穴一次或多次。游荡的雄性比洞穴里的雄性与其他雄性有更多的互动。游荡过程中的求偶行为增加了争夺时间洞穴的额外成本，雌性在游荡过程中的相遇几率没有增加。(2)交配只发生在保持洞穴的时候，但与雌性的每固定次数相遇的比率在保持洞穴的雄性和游荡雄性之间没有差别。(3)该物种的求偶行为模式与其他物种的小提琴类进行了比较。漫游过程中的求偶行为随着洞穴栖息地环境条件的变化而增加。非常成功的地下交配突然减少了流浪者的求爱。
