Intermedia agenda-setting networks

Samuel Stern & Giacomo Livan
We investigate the impact of noise and topology on opinion diversity in social networks. We do so by extending well-established models of opinion dynamics to a stochastic setting where agents are subject both to assimilative forces by their local social interactions, as well as to idiosyncratic factors preventing their population from reaching consensus. We model the latter to account for both scenarios where noise is entirely exogenous to peer influence and cases where it is...

Linking socioeconomic inequalities and type 2 diabetes through obesity and lifestyle factors among Mexican adults: a structural equations modeling approach

Edgar Denova-Gutiérrez, Delfino Vargas-Chanes, Sheyla Hernández, David Napier, Simón Barquera & Paloma Muñoz-Aguirre
Objective. To assess the association between type 2 dia­betes (DM2) and socioeconomic inequalities, mediated by the contribution of body mass index (BMI), physical activity (PA), and diet (diet-DII). Materials and methods. We conducted a cross-sectional analysis using data of adults participating in the Diabetes Mellitus Survey of Mexico City. Socioeconomic and demographic characteristics as well as height and weight, dietary intake, leisure time activity and the presence of DM2 were measured. We fitted a structural...

The apparent exponential radiation of Phanerozoic land vertebrates is an artefact of spatial sampling biases

Roger Close, Roger Benson, John Alroy, Matthew Carrano, Terri Cleary, Emma Dunne, Philip Mannion, Mark Uhen & Richard Butler
There is no consensus about how terrestrial biodiversity was assembled through deep time, and in particular whether it has risen exponentially over the Phanerozoic. Using a database of 38,711 fossil occurrences, we show that the spatial extent of the ‘global’ terrestrial tetrapod fossil record itself expands exponentially through the Phanerozoic, and that this spatial variation explains around 75% of the variation in known fossil species counts. Controlling for this bias, we find that regional-scale terrestrial...

Data from: Spatiotemporal variation in completeness of the early cynodont fossil record and its implications for mammalian evolutionary history

Grace Varnham, Philip Mannion & Christian Kammerer
Mammals are the only surviving group of Cynodontia, a synapsid clade that first appears in the fossil record in the late Permian, ~260 million years ago. Here, using three metrics that capture skeletal completeness, we quantify the quality of the early cynodont fossil record in time and space to evaluate the impact of sampling and preservational biases on our understanding of the group’s evolutionary history. There is no consistent global sampling signal for early cynodonts....

R implementation of the Ecological Risk due to Flow Alteration (ERFA) method

C.L.R. Laize & J.R. Thompson
This application is an implementation of the Ecological Risk due to Flow Alteration (ERFA) method in R language. This method assesses the potential impact of flow change on river ecosystems. Although the code was developed with a geographical focus on southeast Asia (example datasets are provided for the Mekong River Basin), it can be applied for any location where baseline and scenario monthly river flow time series are available. This program is distributed in the...

Data from: Nutritional geometry of mitochondrial genetic effects on male fertility

M. Florencia Camus, James Moore & Max Reuter
Organismal fitness is partly determined by how well the nutritional intake matches sex-specific metabolic requirements. Metabolism itself is underpinned by complex genomic interactions involving products from both nuclear and mitochondrial genomes. Products from these two genomes must coordinate how nutrients are extracted, utilised and recycled; processes vital for fuelling reproduction. Given the complicated nature of metabolism, it is not well understood how the functioning of these two genomes is modulated by nutrients. Here we use...

Defining species when there is gene flow

Ziheng Yang & Xiyun Jiao
Whatever one’s definition of species, it is generally expected that individuals of the same species should be genetically more similar to each other than they are to individuals of another species. Here we show that in the presence of cross-species gene flow, this expectation may be incorrect. We use the multispecies coalescent model with migration or introgression to study the impact of gene flow on genetic differences within and between species and highlight a surprising...

Borane Catalyzed Stereoselective C–H insertion, Cyclopropanation, and Ring-Opening Reactions - data

Ayan Dasgupta, Rasool Babaahmadi, Ben Slater, Brian F Yates, Alireza Ariafard & Rebecca L Melen
Lewis acidic boranes have been shown to be an effective metal-free catalyst for highly selective reactions of donor-acceptor diazo compounds to a range of substrates. The reactions of α-aryl α-diazoesters with nitrogen heterocycles indole or pyrrole selectively generates C3 and C2 C–H insertion products respectively in good to excellent yields even when using unprotected indoles. Alternatively, benzofuran, indene, and alkene substrates give exclusively cyclopropanated products with α-aryl α-diazoesters, whereas the reactions with furans leads to...

Results:...

Phase resolution of heterozygous sites in diploid genomes is important to phylogenomic analysis under the multispecies coalescent model

Ziheng Yang, Jun Huang, Tomas Flouri, Jeremy Bennett & Adam Leache
Genome sequencing projects routinely generate haploid consensus sequences from diploid genomes, which are effectively chimeric sequences with the phase at heterozygous sites resolved at random. The impact of phasing errors on phylogenomic analyses under the multispecies coalescent (MSC) model is largely unknown. Here we conduct a computer simulation to evaluate the performance of four phase-resolution strategies (the true phase resolution, the diploid analytical integration algorithm which averages over all phase resolutions, computational phase resolution using...

Middle Eocene terrestrial paleoweathering and climate evolution in the midlatitude Bohai Bay Basin of Eastern China

Di Chen, Xiongqi Pang, Kun Zhang, Guoyong Liu, Fujie Jiang, Liang Li, Youwei Wang, Min Li & Yang Liu
The middle Eocene is a key time period for understanding Cenozoic cooling of the global climate. In eastern Asia, this time period was marked by deposition of extensive mudstones, shales and interbedded siltstones, especially in the midlatitude Bohai Bay Basin. Still, midlatitude terrestrial records of climate evolution during the middle Eocene are rare. Here, we analyze a continuous, high-resolution record of this period using samples of the shales in the fourth submember of the third...

Coexistence of predators in time: effects of season and prey availability on species activity within a Mediterranean carnivore guild

Marc Vilella, Mariona Ferrandiz-Rovira & Ferran Sayol
1. The degree of coexistence among predators can determine the structure of ecological communities. Niche partitioning is a common strategy applied by species to enhance their coexistence. Diet, habitat or time use can be responsible for segregation among carnivore species, the latter factor being the least studied in Mediterranean ecosystems. Terrestrial medium-sized carnivores (i.e. mesocarnivores) carry out important functions in ecosystems and identifying their interactions is essential for their conservation. 2. In this study, we...

Breaking a species barrier by enabling hybrid recombination

G. Ozan Bozdag, Jasmine Ono, Jai A. Denton, Emre Karakoc, Neil Hunter, Jun-Yi Leu & Duncan Greig
Hybrid sterility maintains reproductive isolation between species by preventing them from exchanging genetic material. Anti-recombination can contribute to hybrid sterility when different species’ chromosome sequences are too diverged to cross-over efficiently during hybrid meiosis, resulting in chromosome mis-segregation and aneuploidy. The genome sequences of the yeasts Saccharomyces cerevisiae and Saccharomyces paradoxus have diverged by about 12% and their hybrids are sexually sterile: nearly all of their gametes are aneuploid and inviable. Previous methods to increase...

The asymptotic behavior of bootstrap support values in molecular phylogenetics

Jun Huang, Yuting Liu, Tianqi Zhu & Ziheng Yang
The phylogenetic bootstrap is the most commonly used method for assessing statistical confidence in estimated phylogenies by non-Bayesian methods such as maximum parsimony and maximum likelihood (ML). It is observed that bootstrap support tends to be high in large genomic datasets whether or not the inferred trees and clades are correct. Here we study the asymptotic behavior of bootstrap support for the ML tree in large datasets when the competing phylogenetic trees are equally right...
