繁殖在生长、生存和未来的繁殖方面都是有成本的，因为繁殖需要消耗可以用于其他功能的能量和时间。雄性寄居蟹在交配前会进行长达数天的配偶守卫行为，而这种守卫行为可能会给雄性带来代价。我们调查是否precopulatory配偶守卫抑郁症的摄食率和蜕皮频率作为繁殖成本的男性寄居蟹Pagurus nigrofascia。男性被分为以下三个大小类：小男性，没有观察到保护女性，中等大小的男性，和大男性，保护女性。在野外，大型雄性的蜕皮频率显著低于其他两个大小类。当雄鸟处于警戒状态时，其取食活动受到严重抑制。在室内实验中，保卫时间受性比的影响，总保卫时间沿着交配次数的增加而增加。然而，在不同性比下，雄蟹的蜕皮频率没有显著差异。我们认为，precopulatory配偶守卫可能会导致繁殖成本的男性P. nigrofascia由于抑郁症的摄食活动，虽然这种成本可能会补偿较高的摄食活动之前和/或之后的守卫。关键词：换羽频率，黑筋膜寄居蟹，交配前守护，繁殖成本ABCDE FG G 1HG IE J> KLM NO PQ R PA> S（Ro #1992）4 TU G VW KLM NO XY Z [AG 1H\J> KLM NO PQ] G 1 H\^_;`& a（Reznick 1985; Oberhauser 1989;巴恩斯和帕森斯2003）4 B cd> efa g hi_jkAG lmnD 4 oE AG pq1/G rs G t uvG> w efXYxy> KLM z {\|}`& coE1~（Parliament & Farquhar 1981;罗宾逊& Doyle 1985;货车Voorhies 1992; Clutton-Brock &兰利1997）4 W G NVW P CDES cd G V N B> S G N PAG; A + QS CD 4 VW PG A t> N N B> d（Ridley 1983; Conlan 1991;约翰逊等人，2001）4 c}_`&\O G t $t v> w> fAG oE>; CD（Elwood & Dick 1990; Sparkes et al. 1996; Jormalainen et al. 2001; Watson et al. 1998）4 YG; oES Q\uv; Δ a G <$t; W> b; P CD ES（Dick & Elwood 1996; Jormalainen & Shuster 1999; Wada et al. 2000; Rondeau & Sainte-Marie 2001; Kamio等人，2003年）4 ¥ t Δ G oE + N YCa § XD> S4 X § X S EG; 1H\^_N N N © XYa « Ak> S（Robinson & Doyle 1985）4 <$P G;/t> CDES 2 3 Hazlett 1966 <$4 <$PAG} a Y μ G °; SCD PG A S4 YG1o Pagurus middendor $i接收日期2009年3月12日接受日期2009年5月23日通讯作者Japanese Journal of Benthology »，1 <$1 <$2 64：25 31（2009）

Reproduction carries costs, in terms of growth, survival, and future reproduction, because reproduction entails the expenditure of energy and time that could be used for other functions. Male Pagurus hermit crabs engage in precopulatory mate guarding behavior for a period of up to several days, and this guarding behavior may entail costs for males. We investigated whether precopulatory mate guarding depresses feeding rate and molting frequency as a cost of reproduction for males in the hermit crab Pagurus nigrofascia. Males were discriminated into the following three size classes: small males that were not observed to guard females, middle-sized males, and large males that guarded females. In the field, molting frequency of the large males was significantly lower than that of the other two size classes. The feeding activity of males was greatly depressed while they were engaged in guarding behavior. The duration of guarding was a#ected by sex ratio in laboratory experiments, the total guarding time increasing along with the number of mates. Molting frequency did not di#er significantly among male crabs under the di#erent sex ratios, however. We suggest that precopulatory mate guarding may entail a reproductive cost for males of P. nigrofascia due to depression of feeding activity although this cost may be compensated for by higher feeding activity before and/or after guarding.
