Early detection of an invasive harvestman in an oceanic island? Remarkable findings of Parabalta reedii (Opiliones, Gonyleptidae) in the Juan Fernández archipelago, Chile

Studies on Neotropical Fauna and Environment, 2020
The Juan Fernández islands (Chile) are a volcanic archipelago, 670 km away from the continent. Arachnids still remain understudied in those islands. We report the first two records of Parabalta reedii (Butler, 1874)) (Opiliones, Gonyleptidae) from the ...

Biogeography of the Juan Fernández Archipelago: vicariance versus long-distance dispersal?

Biological Journal of the Linnean Society
The biota of the Juan Fernández Islands (SE Pacific) provides important information on key evolutionary and biogeographical phenomena. However, a long-standing matter of contention concerns how the archipelago’s various lineages arrived there.

The impact of the rise in the abundance of the long-spined sea urchin (Centrostephanus sylviae) on coastal marine ecosystems of the Juan Fernández Archipelago, Chile

ICES Journal of Marine Science
The Juan Fernández Archipelago (JFA) is a unique ecosystem due to its diversity and high endemism. In recent years, there has been an increase in the populations of the endemic sea urchin Centrostephanus sylviae, generating negative impacts on the ...

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.
