Premise of the study Taxa inhabiting the California Channel Islands exhibit variation in their degree of isolation, but few studies have considered patterns across the entire archipelago. We studied phylogeography of insular Acmispon argophyllus and

The relative roles of chance colonization and subsequent gene flow in the development of insular endemic biotas have been extensively studied in remote oceanic archipelagos, but are less well characterized on nearshore island systems. The current stu

Sibara filifolia (Brassicaceae), Santa Cruz Island Rock Cress, an endangered annual plant endemic to the California Channel Islands which was presumed extinct for nearly 50 years, is currently known from only a few small patches on San Clemente Islan

The California Channel Islands are a group of eight oceanic islands located off the coast of southern California that are substantially closer to the mainland than most other well-studied island systems. The equilibrium theory of island biogeography

The genus Rhinanthus L. is complex, containing many taxonomically unresolved taxa. In this paper we studied genetic variation and species relationships in 15 populations of six Rhinanthus species from three sections. For this purpose, we developed ne

Rhamnus pirifolia Greene (Rhamnaceae), the island redberry, is a small evergreen tree endemic to the California Channel Islands and Guadalupe Island, Mexico. Nine polymorphic microsatellite loci were isolated from the taxon and were screened for vari

The California Channel Islands are unique relative to other island chains due to their close proximity to the California mainland and the fact that individual islands, or groups of islands, vary in their distance to the mainland and other islands. Th

California Channel Island buckwheats are important components of scrub communities on the Channel Islands. A long history of overgrazing by introduced herbivores on San Clemente Island has contributed to scrub vegetation loss and population declines
