在雌性动物择偶过程中，择偶率是影响择偶成本的重要因素之一。在外温动物中，环境温度通常会限制运动性能。此外，雌性会根据其繁殖时间表调整交配采样率，因为如果它们失去交配机会，就会有剩余未受精卵的风险或失去与交配相关的利益。本研究探讨这些影响如何影响雌性交配采样率在温带招潮蟹（Austruca lactea）在外地。每个搜索时间内的采样雄虫数量与环境温度呈凸曲线关系。最适环境温度随雌虫体型增大而升高。这些结果表明，交配采样率是在一个大小依赖的温度约束下，在高温条件下，采样成本较大的女性比较小的个人。此外，当剩余天数较少时，交配采样率增加。雌性会加快取样速度，以确保有一个合适的洞穴进行繁殖。雌性的交配采样率A.因此，泌乳量与环境温度、雌性个体大小和产卵前剩余天数有关。
Rate of mate sampling is one of the critical components associated with sampling costs in female mate choice. In ectotherms, environmental temperature generally constrains locomotion performance. In addition, females will adjust the mate sampling rate depending on their breeding schedule because of the risk of remaining unfertilized eggs or a loss of benefits related to mating, if they lose the opportunity to copulate. This study investigated how these effects influence the rate of female mate sampling in the temperate fiddler crab (Austruca lactea) in the field. The number of sampled males per searching duration formed a convex curve against environmental temperature. The optimal environmental temperature increased with the female body size. These results suggest that mate sampling rate is under a size-dependent temperature constraint, and sampling costs are lower for larger females than smaller individuals under high-temperature conditions. Furthermore, when there were fewer remaining days, the mate sampling rate increased. Females would hasten the sampling rate to ensure a suitable burrow for breeding. Mate sampling rate in femaleA. lacteais therefore associated with environmental temperature, female body size and remaining days until oviposition.
