Data from: Phenotypic integration of the cervical vertebrae in the Hominoidea (Primates)

Catalina Isabel Villamil
Phenotypic integration and modularity represent important factors influencing evolutionary change. The mammalian cervical vertebral column is particularly interesting in regards to integration and modularity because it is highly constrained to seven elements, despite widely variable morphology. Previous research has found a common pattern of integration among quadrupedal mammals, but integration patterns also evolve in response to locomotor selective pressures like those associated with hominin bipedalism. Here, I test patterns of covariation in the cervical vertebrae...

Data from: Experimental evidence that female rhesus macaques (Macaca mulatta) perceive variation in male facial masculinity

Kevin A. Rosenfield, Stuart Semple, Alexander V. Georgiev, Dario Maestripieri, James P. Higham & Constance Dubuc
Among many primate species, face shape is sexually dimorphic, and male facial masculinity has been proposed to influence female mate choice and male-male competition. However, whether conspecifics pay attention to facial masculinity has only been assessed in humans. Here, working with free-ranging rhesus macaques, Macaca mulatta, we used a two-alternative look-time experiment to test whether females perceive male facial masculinity. We presented 107 females with pairs of images of male faces – one more masculine...

Data from: Health insurance coverage with or without a nurse-led task shifting strategy for hypertension control: a pragmatic cluster randomized trial in Ghana

Gbenga Ogedegbe, Jacob Plange-Rhule, Joyce Gyamfi, William Chaplin, Michael Ntim, Kingsley Apusiga, Juliet Iwelunmor, Kwasi Yeboah Awudzi, Kofi Nana Quakyi, Jazmin N. Mogavero, Kiran Khurshid, Bamidele Tayo & Richard Cooper
Rationale: Poor access to care and physician shortage are major barriers to hypertension control in sub-Saharan Africa. Implementation of evidence-based systems-level strategies targeted at these barriers are lacking. Objective: To evaluate the comparative effectiveness of provision of health insurance coverage (HIC) alone versus a nurse-led task-shifting strategy for hypertension control (TASSH) plus HIC on systolic BP reduction among patients with uncontrolled hypertension in Ghana. Methods and Findings: Using a pragmatic cluster-randomized trial, 32 community health...

Data from: Encephalization and longevity evolved in a correlated fashion in Euarchontoglires but not in other mammals

Alex R. DeCasien, Nicole A. Thompson, Scott A. Williams & Milena R. Shattuck
Across mammals, encephalization and longevity show a strong correlation. It is not clear, however, whether these traits evolved in a correlated fashion within mammalian orders, or when they do, whether one trait drives changes in the other. Here, we compare independent and correlated evolutionary models to identify instances of correlated evolution within six mammalian orders. In cases of correlated evolution, we subsequently examined transition patterns between small/large relative brain size and short/long lifespan. In four...

Data from: Temporal transcriptional logic of dynamic regulatory networks underlying nitrogen signaling and use in plants

Kranthi Varala, Amy Marshall-Colón, Jacopo Cirrone, Matthew D. Brooks, Angelo V. Pasquino, Sophie Léran, Shipra Mittal, Tara M. Rock, Molly B. Edwards, Grace J. Kim, Sandrine Ruffel, W. Richard McCombie, Dennis Shasha & Gloria M. Coruzzi
This study exploits time, the relatively unexplored fourth dimension of gene regulatory networks (GRNs), to learn the temporal transcriptional logic underlying dynamic nitrogen (N) signaling in plants. Our “just-in-time” analysis of time-series transcriptome data uncovered a temporal cascade of cis elements underlying dynamic N signaling. To infer transcription factor (TF)-target edges in a GRN, we applied a time-based machine learning method to 2,174 dynamic N-responsive genes. We experimentally determined a network precision cutoff, using TF-regulated...

Allen, Nina Attias, Tal Avgar, Hattie Bartlam-Brooks, Buuveibaatar Bayarbaatar, Jerrold L. Belant, Alessandra Bertassoni, Dean Beyer, Laura Bidner, Floris M. Van Beest, Stephen Blake, Niels Blaum, Chloe Bracis, Danielle Brown, P. J. Nico De Bruyn, Francesca Cagnacci, Justin M. Calabrese, Constança Camilo-Alves … & Thomas Mueller
Animal movement is fundamental for ecosystem functioning and species survival, yet the effects of the anthropogenic footprint on animal movements have not been estimated across species. Using a unique GPS-tracking database of 803 individuals across 57 species, we found that movements of mammals in areas with a comparatively high human footprint were on average one-half to one-third the extent of their movements in areas with a low human footprint. We attribute this reduction to behavioral...

Data from: The rice paradox: multiple origins but single domestication in Asian rice

Jae Young Choi, Adrian E Platts, Dorian Q Fuller, Yue-Ie Hsing, Rod A Wing & Michael D Purugganan
The origin of domesticated Asian rice (Oryza sativa) has been a contentious topic, with conflicting evidence for either single or multiple domestication of this key crop species. We examined the evolutionary history of domesticated rice by analyzing de novo assembled genomes from domesticated rice and its wild progenitors. Our results indicate multiple origins, where each domesticated rice subpopulation (japonica, indica, and aus) arose separately from progenitor O. rufipogon and/or O. nivara. Coalescence-based modeling of demographic...

Landis, A. Levesque, K. Rothe, M. Balaan, B. Dimitt, B. Fortin, N. Ettinger, A. Pierre, L. Yarmus, K. Oakjones-Burgess, N. Desai, Z. Hammoud, A. Sorenson, R. Murali … & F. Allison
Background: Lung nodules are a diagnostic challenge, with an estimated yearly incidence of 1.6 million in the United States. This study evaluated the accuracy of an integrated proteomic classifier in identifying benign nodules in patients with a pretest probability of cancer (pCA) ≤ 50%. Methods: A prospective, multicenter observational trial of 685 patients with 8- to 30-mm lung nodules was conducted. Multiple reaction monitoring mass spectrometry was used to measure the relative abundance of two...

Data from: Disentangling the genetic effects of refugial isolation and range expansion in a trans-continentally distributed species

Brendan N. Reid, Jamie M. Kass, Seth Wollney, Evelyn L. Jensen, Michael A. Russello, Ella M. Viola, Jenna Pantophlet, John B. Iverson, Marcus Z. Peery, Christopher J. Raxworthy & Eugenia Naro-Maciel
In wide-ranging taxa with historically dynamic ranges, past allopatric isolation and range expansion can both influence the current structure of genetic diversity. Considering alternate historical scenarios involving expansion from either a single refugium or from multiple refugia can be useful in differentiating the effects of isolation and expansion. Here, we examined patterns of genetic variability in the trans-continentally distributed painted turtle (Chrysemys picta). We utilized an existing phylogeographic dataset for the mitochondrial control region and...

Data from: Intrinsically regulated learning is modulated by synaptic dopamine signaling

Pablo Ripollés, Laura Ferreri, Ernest Mas-Herrero, Helena Alicart, Alba Gómez-Andrés, Josep Marco-Pallares, Rosa Maria Antonijoan, Toemme Noesselt, Marta Valle, Jordi Riba & Antoni Rodriguez-Fornells
We recently provided evidence that an intrinsic reward-related signal-triggered by successful learning in absence of any external feedback-modulated the entrance of new information into long-term memory via the activation of the dopaminergic midbrain, hippocampus, and ventral striatum (the SN/VTA-Hippocampal loop; Ripollés et al., 2016). Here, we used a double-blind, within-subject randomized pharmacological intervention to test whether this learning process is indeed dopamine-dependent. A group of healthy individuals completed three behavioral sessions of a language-learning task...

Data from: Ancient mechanisms for the evolution of the bicoid homeodomain's function in fly development

Qinwen Liu, Pinar Onal, Rhea R. Datta, Julia M. Rogers, Urs Schmidt-Ott, Martha L. Bulyk, Stephen Small & Joseph W. Thornton
The ancient mechanisms that caused developmental gene regulatory networks to diversify among distantly related taxa are not well understood. Here we use ancestral protein reconstruction, biochemical experiments, and developmental assays of transgenic animals carrying reconstructed ancestral genes to investigate how the transcription factor Bicoid (Bcd) evolved its central role in anterior-posterior patterning in flies. We show that most of Bcd's derived functions are attributable to evolutionary changes within its homeodomain (HD) during a phylogenetic interval...

Richerson, Philippe Ryvlin & Samden D. Lhatoo
Objective: To characterize peri-ictal apnea and post-ictal asystole in generalized convulsive seizures (GCS) of intractable epilepsy. Methods: Prospective, multi-center epilepsy monitoring study of autonomic and breathing biomarkers of SUDEP in patient’s ≥18 years old with intractable epilepsy and monitored GCS. Video EEG, thoraco-abdominal excursions, nasal airflow, capillary oxygen saturation and electrocardiography were analyzed. Results: We studied 148 GCS in 87 patients. Nineteen patients had generalized epilepsy, 65 had focal, one had both and in two,...

Data from: A resource-rational theory of set size effects in human visual working memory

Ronald Van Den Berg & Wei Ji Ma
Encoding precision in visual working memory decreases with the number of encoded items. Here, we propose a normative theory for such set size effects: the brain minimizes a weighted sum of an error-based behavioral cost and a neural encoding cost. We construct a model from this theory and find that it predicts set size effects. Notably, these effects are mediated by probing probability, which aligns with previous empirical findings. The model accounts well for effects...
