Abstract

PEQUENO R., Germán  and  SAEZ B., Sylvia. The littoral fishes of the Juan Fernandez archipelago (Chile): endemism and ichthyogeographical relationships. Investig. mar. [online]. 2000, vol.28, pp.27-37. ISSN 0717-7178.  http://dx.doi.org/10.4067/S0717-71782000002800004.

According to current knowledge on ichthyofaunistic composition of Juan Fernandez archipelago, those species typically littoral (inter and subtidal) were selected to analize which of them are endemic and which ones are represented in other regions. Endemic species correspond to 25.5%; those represented westward are 19.6% and the eastward ones are 15.6%. Transpacific species represent 9.8% of the total, whereas 29.4% of the species are in common with Desventuradas islands. A slightly higher link with Polynesian and West Pacific areas is recognised, if compared with the proper Southamerican coastlines. This supports to give background to the idea that the Indo-West Pacific zoogeographic region, at least in relation to fishes, can be extended to this oceanic islands

Keywords : ichthyogeography; Juan Fernandez archipelago; Pacific ocean; Chile.
