The Vegetation of Robinson Crusoe Island (Isla Masatierra), Juan Fernandez Archipelago, Chile

Pacific Science, 2002
Robinson Crusoe Island of the Juan Fernández Archipelago, as is the case with many oceanic islands, has experienced strong human disturbances through exploitation of resources and introduction of alien biota. To understand these impacts and for purposes of diversity and resource management, an accurate assessment of the composition and structure of ...

Predicting Future Threats to the Native Vegetation of Robinson Crusoe Island, Juan Fernandez Archipelago, Chile

Conservation Biology, 2003
Abstract:  The Juan Fernandez Archipelago, a Chilean national park and biosphere reserve, is 700 km west of continental Chile. Invasive plant species pose major threats to the native, highly endemic vegetation, especially on Robinson Crusoe Island (Mas a Tierra), where there is a permanent settlement.

A new species of Megalachne (Poaceae) endemic to Alejandro Selkirk Island, Juan Fernandez Archipelago, Chile

Phytotaxa, 2019
A new species of Megalachne (Poaceae) endemic to Alejandro Selkirk Island, Juan Fernandez Archipelago, Chile, is described and illustrated, based on morphological characters. This species is differentiated from others of the genus by its long lemma awn (5–8.5 cm) and by the number of flowers in the spikelet (2–4). The taxon has been reported previously

The spider genus Stictonanus Millidge, 1991 in the Juan Fernandez Archipelago (Araneae, Linyphiidae): systematics and biogeography

Invertebrate Systematics
We studied the systematics of the Juan Fernandez linyphiid species originally classified in the genus Juanfernandezia Koçak & Kemal, 2008. In an earlier study, we had hypothesized that the two Juanfernandezia species, each endemic to a single island, form a clade that was sister to the southern South American genus Notholepthyphantes Millidge, 1985.

He, Sr and Nd isotopic variations in lavas from the juan fernandez archipelago, SE pacific

Contributions to Mineralogy and Petrology, 1993
Helium, Sr, and Nd isotopic ratios and major and trace element compositions have been measured on a suite of lavas from the intra-plate volcanos of the Juan Fernandez Archipelago, Chile. Lavas from the islands of Mas Afuera and Mas a Tierra and from Monte Alpha and Friday seamounts have Sr and Nd isotopic ratios lying on the low143Nd/144Nd side of the ...
