摘要：

The ontogeny of behavioral responses of larvae of the crabs Rhithropanopeus harrisii and Neopanope sayi to rates of change in temperature were analyzed. A temperature decrease evoked an ascent in both species. Threshold rates of decrease for Stages I and IV zoeae of R. harrisii, and Stage I zoeae of N. sayi, were 0.06, 0.1, and 0.09°C min-1, respectively. Stage IV zoeae of N. sayi were unresponsive to any rate of decrease. Larvae descended upon a temperature increase. For Stages I and IV zoeae of R. harrisii and Stage I of N. sayi the threshold rates of temperature increase were 0.07, 0.24, and 0.18°C min-1, respectively. Stage IV zoeae of N. sayi were again unresponsive. -from Author
