Spatial Variation in Coral Diversity and Reef Complexity in the Galápagos: Insights from Underwater Photogrammetry and New Data Extraction Methods

open access: yesRemote Sensing
Corals in the Galápagos present diverse reef configurations from biogenic coral reefs to coral communities growing on rocks and sand. These corals have experienced decades of disturbances including recurring El Niño and mass bleaching events.

The extension of the taxon cycle model to island plants: insights from the Canarian vascular flora

open access: yesBiological Reviews, EarlyView.
ABSTRACT Taxon cycle models describe eco‐evolutionary patterns of lineage colonization, diversification, and decline across archipelagos, inferring an important role for competition amongst ecologically similar taxa in driving concurrent niche changes.

Loss, persistence and reversal of phenotypic traits

open access: yesBiological Reviews, EarlyView.
ABSTRACT The irreversibility of complex trait loss has long been a tenet of evolutionary biology. However, this idea is increasingly at odds with the numerous documented exceptions across the Tree of Life. We synthesise this growing body of evidence across a diverse array of taxa and traits, exploring the evolutionary conditions that enable ...

Craters of habit: Patterns of deformation in the western Galápagos

open access: yesVolcanica
The western Galápagos islands of Fernandina and Isabela comprise six active volcanoes that have deformed since first observed by satellite radar in the early 1990s.

Basin-scale sources and pathways of microplastic that ends up in the Galápagos Archipelago [PDF]

open access: yesOcean Science, 2019
The Galápagos Archipelago and Galápagos Marine Reserve lie 1000 km off the coast of Ecuador and are among the world's most iconic wildlife refuges. However, plastic litter is now found even in this remote island archipelago.

Building a Robust Investigator‐Initiated Platform: The I‐CARE Experience

open access: yesClinical Pharmacology &Therapeutics, EarlyView.
Investigator‐initiated studies that include information collected by patients are rising, but limited data is available on patient and investigator experience in this setting. The I‐CARE cohort included patients with inflammatory bowel disease (IBD) monthly collecting clinical information in 15 countries for up to 6 years.

Concomitant 5‐Aminosalicylic Acid Does Not Affect the Efficacy of Janus Kinase Inhibitors in Ulcerative Colitis

open access: yesClinical Pharmacology &Therapeutics, EarlyView.
We evaluated whether concomitant 5‐aminosalicylic acid (5‐ASA) influences clinical remission in patients with ulcerative colitis (UC) receiving Janus kinase inhibitors (JAKi). In this retrospective, multicenter cohort study, UC patients receiving tofacitinib (n = 181), upadacitinib (n = 313), or filgotinib (n = 139) were included.

Urban Land Cover Change in Ecologically Fragile Environments: The Case of the Galapagos Islands

open access: yesLand, 2018
The Galapagos Islands are a unique sanctuary for wildlife and have gone through a fluctuating process of urbanization in the three main inhabited islands. Despite being colonized since the 1800s, it is during the last 25 years that a dramatic increase in

Insights Into the Origins and Compositions of Mantle Plumes: A Comparison of Galápagos and Hawai'i

open access: yesGeochemistry, Geophysics, Geosystems, 2020
The Galápagos and Hawai'i archipelagos are formed by mantle plumes originating at the large low shear velocity province (LLSVP) boundary. We report new high‐precision Pb, Sr, Nd, and Hf isotopic analyses on 83 Galápagos samples and compare them with ...
