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 ...

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

An Outline of the Geology of the Juan Fernandez Archipelago

Geological Magazine, 1967
AbstractThe Juan Fernandez Archipelago, located off the coast of Chile, comprises a group of three small, considerably eroded volcanic islands, probably of late Tertiary age. Traces of old craters or calderas have been recognized on Robinson Crusoe Island which is built mainly of basaltic lava flows, many of them picrite-basalts. Coarse-grained ejected

Filamentous Brown Algae from the Juan Fernandez Archipelago (Chile): Contribution of Laboratory Culture Techniques to a Phytogeographic Survey

Botanica Marina, 1994
The marine benthic floras of many remote localities are poorly studied. Sampling, during a short visit, followed by laboratory culture techniques can be employed to extend the flora lists. Islas Robinson Crusoe and Santa Clara off the coast of central Chile were visited for 10 days in 1991.

Trophic ecology of abundant reef fish in a remote oceanic island: coupling diet and feeding morphology at the Juan Fernandez Archipelago, Chile

Journal of the Marine Biological Association of the United Kingdom, 2013
The trophic structure of organisms is an important aspect of the ecosystem as it describes how energy is transferred between different trophic levels. Here, we studied the diet and foraging ecology of 144 individuals belonging to five abundant fish species of subtidal habitats at Isla Robinson Crusoe.

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.
