The impact of fishing on a highly vulnerable ecosystem, the case of Juan Fernández Ridge ecosystem.

PLoS ONE, 2019
The Juan Fernández Ridge (JFRE) is a vulnerable marine ecosystem (VME) located off the coast of central Chile formed by the Juan Fernández Archipelago and a group of seamounts.

Insights Into Mantle Plume Geochemistry From Machine Learning

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 1, January 2025.
Abstract Oceanic island basalts are the products of mantle plume melting and their chemistry provides insights into the Earth's deep interior. We report a statistical and machine learning study of 8 radiogenic isotopes and 19 incompatible trace element ratios in basalts from 27 oceanic island volcanic chains associated with mantle plumes compiled from ...

Intercolonial Cinnamon: Fashioning Connections from the Eighteenth to Mid‐Nineteenth Centuries

History, Volume 110, Issue 389, Page 49-67, January 2025.
Abstract It is well known that the quest for spices fuelled navigational endeavours during early modern history, acting as a gateway to conquest. Historians from the field have often focused on the relations between the colonies and the colonised, but what role did this play in the forging of intercolonial connections? By delving into the allure of one

Phylogenomics and phylogeographic model testing using convolutional neural networks reveal a history of recent admixture in the Canarian Kleinia neriifolia

Molecular Ecology, Volume 33, Issue 21, November 2024.
Abstract Multiple‐island endemics (MIE) are considered ideal natural subjects to study patterns of island colonization that involve recent population‐level genetic processes. Kleinia neriifolia is a Canarian MIE widespread across the archipelago, which exhibits a close phylogenetic relationship with species in northwest Africa and at the other side of ...

Population Genomics of Adaptive Radiations: Exceptionally High Levels of Genetic Diversity and Recombination in an Endemic Spider From the Canary Islands

Molecular Ecology, Volume 33, Issue 22, November 2024.
ABSTRACT The spider genus Dysdera has undergone a remarkable diversification in the oceanic archipelago of the Canary Islands, with ~60 endemic species having originated during the 20 million years since the origin of the archipelago. This evolutionary radiation has been accompanied by substantial dietary shifts, often characterised by phenotypic ...

Cryptic Diversity of Mediterranean Neogoniolithon (Corallinales, Corallinophycidae, Rhodophyta)

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 34, Issue 10, October 2024.
ABSTRACT Neogoniolithon is a widespread genus of non‐geniculate coralline algae in the Mediterranean Sea. Three vaguely differentiated species have been reported in the region. This study examined the diversity of Neogoniolithon in the Mediterranean by inferring phylogenies using psbA and COI‐5P markers, applying delimitation algorithms and comparing ...

Seamounts in the southeastern Pacific Ocean and biodiversity on Juan Fernandez seamounts, Chile Montes submarinos en el océano Pacífico suroriental y biodiversidad en el cordón de Juan Fernández, Chile

Latin American Journal of Aquatic Research, 2009
Seamounts are vulnerable marine ecosystems. In Chile, information on these ecosystems is quite scarce; thus, a compilation of information on their geographical distribution and biodiversity is presented herein. A total of 118 seamounts distributed in the
