ホンヤドカリ属を対象として、オスとメスの成長と繁殖の資源配分様式を調べた。本属の一部の種では、交尾直前にメスが脱皮することがあり、繁殖期中にも成長する。本研究の結果、脱皮する個体は、とくに産卵間隔が長い傾向が強く、抱卵数も変異が大きかった。オスも配偶行動によって摂餌行動が抑制されるため、繁殖に費やす時間の増加が成長を低下させることが示唆されたが、実験ではそれを強く支持する結果は得られなかった。

The resource allocation model of growth and reproduction of the plant is adjusted. A part of this genus is divided into two parts: the first part of the genus is divided into two parts: the first part is divided into three parts: the second part is divided into four parts: the first part is divided into three parts: the first part is divided into four parts: the first part is divided into four parts: the second part is divided into four parts: the first part is divided into four parts: the first part is divided into four parts: the second part is divided into four parts: the first part is divided into four parts: the first part is divided into four parts: the second part is divided into four parts: the first part is divided into four parts: the first part is divided into four parts: the second part is divided into four parts: the first part is divided into four parts: the second part is divided into four parts: the first part is divided into four parts: the second part is divided into four parts: the first part is divided into four parts: the second part is divided into four parts: the third part is divided into four parts: the first part is divided into four parts: the second part is divided into four parts: the third part is divided into four parts: the first The results of this study showed that the individual had a strong tendency to have a long egg interval and a large number of eggs. The result of the "spouse action" is that it inhibits growth, increases reproductive costs, and decreases growth.
