REPRODUCTION IN THREE SPECIES OF INTERTIDAL BARNACLES FROM CENTRAL CALIFORNIA

Reproduction in Three Species of Intertidal Barnacles from Central California

The reproductive biology of eastern Atlantic barnacles has been studied extensively, with emphasis on the role of temperature in regulating reproduction (e.g., Crisp, 1950, 1954; Patel and Crisp, 1960a; Barnes, 1963; Barnes and Stone, 1973). However, there has been much less work on cirripedes elsewhere in the world. This paper compares the reproductive cycles and brood production of three spec...

Phylogeography of Supralittoral Rocky Intertidal Ligia Isopods in the Pacific Region from Central California to Central Mexico

BACKGROUND Ligia isopods are widely distributed in the Pacific rocky intertidal shores from central California to central Mexico, including the Gulf of California. Yet, their biological characteristics restrict them to complete their life cycles in a very narrow range of the rocky intertidal supralittoral. Herein, we examine phylogeographic patterns of Ligia isopods from 122 localities between ...
