Reproductive aspects of Chiton virgulatus in Bahía de La Paz, Gulf of California, Mexico

Abstract: This study analyzed the reproductive cycle of Chiton virgulatus and its relationship with air temperature (AT) sea and surface temperature (SST), photoperiod, and tidal cycle (TC) in Bahía de La Paz, in the coast of the Gulf of California. Monthly samples were collected from September 2008...

Monthly samples were collected from September 2008 to September 2009.
