A song of wind and ice: increased frequency of marine cold-spells in southwestern Patagonia and their possible effects on giant kelp forests

Alejandra Mora-Soto, Catalina Aguirre, Jose Luis Iriarte, Mauricio Palacios, Erasmo C. Macaya & Marc Macias-Fauria
In contrast to other coastal regions of the world, the giant kelp (Macrocystis pyrifera) ecosystem in southwestern Patagonia has been persistent in area and associated biodiversity in the last decades. In this ecoregion, Sea Surface Temperature (SST) records have consistently remained below the upper thermal threshold for kelp survival, however no studies have analysed the spatiotemporal variability of SSTs and their anomalies across the geographical diversity of the southwestern Patagonian coastline. We explored the geographical...

Phylogenomic discordance in the Eared Seals is best explained by incomplete lineage sorting following explosive radiation in the Southern Hemisphere

The phylogeny and systematics of fur seals and sea lions (Otariidae) have long been studied with diverse data types, including an increasing amount of molecular data. However, only a few phylogenetic relationships have reached acceptance pointing at strong gene-tree species tree discordance. Divergence times in the group also vary largely between studies. These uncertainties impeded the understanding of the biogeographical history of the group, such as when and how trans-equatorial dispersal and subsequent speciation events...

Data from: Spatiotemporal spike coding of behavioral adaptation in the dorsal anterior cingulate cortex

Laureline Logiaco, René Quilodran, Emmanuel Procyk & Angelo Arleo
The frontal cortex controls behavioral adaptation in environments governed by complex rules. Many studies have established the relevance of firing rate modulation after informative events signaling whether and how to update the behavioral policy. However, whether the spatiotemporal features of these neuronal activities contribute to encoding imminent behavioral updates remains unclear. We investigated this issue in the dorsal anterior cingulate cortex (dACC) of monkeys while they adapted their behavior based on their memory of feedback...

Data from: Virtual patients and sensitivity analysis of the Guyton model of blood pressure regulation: towards individualized models of whole-body physiology

Robert Moss, Thibault Grosse, Ivanny Marchant, Nathalie Lassau, François Gueyffier & S. Randall Thomas
Mathematical models that integrate multi-scale physiological data can offer insight into physiological and pathophysiological function, and may eventually assist in individualized predictive medicine. We present a methodology for performing systematic analyses of multi-parameter interactions in such complex, multi-scale models. Human physiology models are often based on or inspired by Arthur Guyton’s whole-body circulatory regulation model. Despite the significance of this model, it has not been the subject of a systematic and comprehensive sensitivity study. Therefore,...
