Wandering Male Uca Arcuata and Analysis of the Social Behavior

(1)雄性招潮蟹通过从洞穴接近和游荡来求爱。持穴雄鸟与无穴雄鸟的相遇率差异不显著。洞穴持有男性往往造成流离失所的女性比流浪男性流浪。穴居雄鸟的行为并不减少其附近潜在配偶的可用性。穴居雄鸟在减少与雌性的接触后倾向于开始游荡。流浪的女性引诱流浪的男性经常发生流浪的男性所造成的其他男性。大多数流浪男性，流离失所的洞穴主人使用的洞穴一次或多次后，取代业主。流浪的男性经历了更多的互动与其他男性比穴居男性没有。游猎期求偶有额外的时间洞穴争夺成本，游猎期雌虫的相遇率没有增加。(2)交配只发生在举行洞穴，但每一个固定数量的女性遇到的率是没有不同的洞穴举行男性和流浪男性。(3)并与其它种类的小提琴手进行了求偶行为模式的比较。求偶流浪期间增加有关的穴居栖息地的环境条件。非常成功的地下交配突然减少了流浪者的求爱。

(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.
