… The present work is an experimental study of factors affecting the distribution and
abundance or red (Strongyliocentrotus franciscanus (A-Agàssiz) ) and purple (S- purpuratus
(Stimpson ) . Both regular echinoids (Class Echinoidea, Order Camarodonta) are common
marine herbivores whose present geogrophical ranges overlap completely on the west …
Field experiments in tidepools and boulder fields We have seen that purple urchins are
more abundant in high than in low intertidal habitats, and extend higher than reds, which …
