K. Bowie, Jonathan Waters, Elie Poulin & Juliana Vianna
Delimiting recently diverged species is challenging. During speciation, genetic differentiation may be distributed unevenly across the genome, as different genomic regions can be subject to different selective pressures and evolutionary histories. Reliance on limited numbers of genetic markers that may be underpowered can make species delimitation even more challenging, potentially resulting in taxonomic inconsistencies. Rockhopper penguins of the genus Eudyptes comprise three broadly recognized taxa: northern (E. moseleyi), southern (E. chrysocome), and eastern rockhopper (E....

María Elena Ceballos, Carolina Nuñez, Javier Uribe, María Magdalena Vera, Ricardo Castro, Patricia García, Gabriel Arriata, Vicente Gándara, Camila Vargas, Angélica Dominguez, Inés Cerón, Pablo Born & Eduardo Espíndola
Abstract Background Patients with COVID-19 receiving mechanical ventilation may become aggravated with a secondary respiratory infection. The aim of this study was to describe secondary respiratory infections, their predictive factors, and outcomes in patients with COVID-19 requiring mechanical ventilation. Methods A cohort study was carried out in a single tertiary hospital in Santiago, Chile, from 1st June to 31st July 2020. All patients with COVID-19 admitted to the intensive care unit that required mechanical ventilation...

Thermal tolerance in Drosophila: repercussions for distribution, community coexistence and responses to climate change

José M. Alruiz, Ignacio Peralta-Maraver, Francisco Bozinovic, Mauro Santos & Enrico L. Rezende
Here we combined controlled experiments and field surveys to determine if estimates of heat tolerance predict distributional ranges and phenology of different Drosophila species in southern South America. We contrasted thermal death time curves, which consider both magnitude and duration of the challenge to estimate heat tolerance, against the thermal range where populations are viable based on field surveys in an 8-yr longitudinal study. We observed a strong correspondence of the physiological limits, the thermal...

Data from: The origins of global biodiversity on land, sea, and freshwater

Cristian Román-Palacios, Daniela Moraga-López & John Wiens
Many biodiversity studies focus on explaining high tropical species richness, but an equally dramatic yet understudied pattern involves the divergent richness of land, sea, and freshwater. Here, we reveal the origins of these richness differences among habitats across animals and plants. Most plant and animal species are terrestrial, although these habitats cover only ~28% of Earth’s surface. Marine habitats have fewer species over a larger area (~70%). Freshwater habitats have relatively high richness and exceptional...

Alignments and phylogenetic tree from: A new endemic species of Loasa ser. Macrospermae from northern Chile

Ludovica Santilli, Nicolas Lavandero, Claire De Schrevel, Philippe Dandois & Rafael Acuña
Alignments used for the phylogenetic work and raw phylogenetic trees obtained. A new species of Loasa, endemic‌ ‌to‌ ‌the‌ ‌northern ‌Andes‌ ‌‌of‌ ‌Chile‌ is described and evaluated, under the IUCN criteria for conservation, as critically endangered. Molecular analyses based on plastid markers place the new species within the Loasa ser. Macrospermae, with high support, and specifically as sister to Loasa acerifolia. A key to and comparative plates including all the 13 known species of Loasa...

Health and economic effects on patients with type 2 diabetes mellitus in the long run: predictions for the Chilean population

Manuel Antonio Espinoza, Tomas Abbott, Alvaro Passi & Carlos Balmaceda
Abstract Background Diabetes is associated to a high financial and disease burden, explaining a large proportion of expenditure of the health system in one year. The purpose of this study was to estimate long-term costs and health outcomes of recently diagnosed patients with type 2 diabetes in Chile. Methods Cost and consequence study based on mathematical discrete event simulation (DES) model. We modelled expected costs (USD) and quality-adjusted life-years (QALYs) from diagnosis to death (or...

Le plébiscite de 1988 : le début de la fin de la dictature militaire chilienne (Les Études du CERI, n°239-240)

Manuel Gárate Château
Au-delà des débats relatifs aux caractéristiques de la transition politique et à l’héritage politique et social encore vivace de la dictature civico-militaire du général Pinochet, le 5 octobre 1988 reste une date-clé pour les Chiliens, celle du retour à la démocratie.

ASKXXI: Ecologies of Interdisciplinary Research and Practice in Art + Science and Technology

Genevieve Tremblay, Jeff Brice, Fernanda X. Oyarzún Dunlop, Nélida Pohl & Belén Gallardo
ASKXXI: Arts + Science Knowledge Building and Sharing in the XXI (21st) Century was a US-Chile pilot program fostering inquiry and inter-hemispheric collaboration in art, emerging technologies, and the ecological sciences. Funded through an US Embassy public diplomacy grant, ASKXXI was an adaptive curriculum model situated on a collaborative platform of academic partners. This model provided freedom, flexibility and responsiveness to dynamic learning and professional development opportunities. The year-long pilot was customized to a jury-selected...

Adaptive effects of parental and developmental environments on offspring survival, growth, and phenotype

Daphne Cortese, Amélie Crespel, Suzanne Mills, Tommy Norin, Shaun Killen & Ricardo Beldade
Phenotypic adjustments to environmental variation are particularly relevant to cope with putative environmental mismatches often imposed by natal dispersal. We used an inter-generational cross-transplant field-based experiment to evaluate the morphological and physiological effects of parental and post-settlement water flow environments on the orange-fin anemonefish Amphiprion chrysopterus through ontogeny (at pre- and post-settlement stages). Offspring born from parents under high water flow had an 18% higher caudal fin aspect ratio (a compound measure of shape) at...

Data from: Pre-domestication bottlenecks of the cultivated seaweed Gracilaria chilensis

Oscar R. Huanel, Suany Quesada-Calderón, Cristian Ríos, Saraí Morales-González, Pablo Saenz-Agudelo, Wendy A. Nelson, Natalia Arakaki, Stéphane Mauger, Sylvain Faugeron & Marie-Laure Guillemin
Gracilaria chilensis is the main cultivated seaweed in Chile. The low genetic diversity observed in the Chilean population has been associated with the over-exploitation of natural beds and/or the founder effect that occurred during the post-glacial colonization from New Zealand. How these processes have affected its evolutionary trajectory before farming and incipient domestication is poorly understood. In this study, we used 2,232 SNPs to assess how the species' evolutionary history in New Zealand (its region...

Heat tolerance of marine ectotherms in a warming Antarctica

Enrico Rezende, Andres Molina, José Pulgar & Mauricio Carter
Global warming is affecting the Antarctic continent in complex ways. Because Antarctic organisms are specialized to living in the cold, they are vulnerable to increasing temperatures, though quantitative analyses of this issue are currently lacking. Here we compiled a total of 184 estimates of heat tolerance belonging to 39 marine species and quantified how survival is affected concomitantly by the intensity and duration of a thermal stress. Species exhibit thermal limits displaced towards colder temperatures,...
