Book Description
Excerpt from Proceedings of the California Academy of Sciences, 1907, Vol. 33 With few exceptions, the islands Of the eastern tropical Pacific, from the Revilla Gigedos to the Galapagos, have been treated by American workers in a purely American context. That this was too restricted a concept, particularly as regards Clipperton Island, became increasingly apparent during the course of this study as one Species after another proved to be Of west-pacific origin or derivation. This should not have been surprising, for perhaps no other island in the eastern Pacific is SO favorably Situated to receive migrants from the western Pacific, or to provide the accustomed habitat once they have arrived. Accord ingly, Clipperton Island may be said to belong neither to the Panamic nor to the Polynesian fauna alone, but to both, since each has contributed substantially to its microcosm. An evaluation Of the trans-pacific increment called for extralimital experi ence, supplied by two summers' field work in the Marshall Islands, with Observa tions in Hawaii while en route. Familiarity with the indo-pacific coral reef fauna at Eniwetok, an atoll in the western Pacific, facilitated recognition Of the west-pacific element present at Clipperton, the only atoll in the eastern Pacific, and made possible the assignment Of each species to its characteristic habitat despite the paucity Of accompanying ecological data. It also provided a working acquaintance with the voluminous and scattered literature needed to identify the non-american species, for which no encompassing monograph exists, and to determine their provenance.
