Data from: The origin and genetic differentiation of the socially parasitic aphid Tamalia inquilinus

Don G. Miller, Sarah P. Lawson, David C. Rinker, Heather Estby & Patrick Abbot
Social and brood parasitisms are nonconsumptive forms of parasitism involving the exploitation of the colonies or nests of a host. Such parasites are often related to their hosts and may evolve in various ecological contexts, causing evolutionary constraints and opportunities for both parasites and their hosts. In extreme cases, patterns of diversification between social parasites and their hosts can be coupled, such that diversity of one is correlated with or even shapes the diversity of...

Data from: Genetics of plasminogen activator inhibitor-1 (PAI-1) in a Ghanaian population

Marquitta J. White, Nuri M. Kodaman, Reed H. Harder, Folkert W. Asselbergs, Douglas E. Vaughan, Nancy J. Brown, Jason H. Moore & Scott M. Williams
Plasminogen activator inhibitor 1 (PAI-1), a major modulator of the fibrinolytic system, is an important factor in cardiovascular disease (CVD) susceptibility and severity. PAI-1 is highly heritable, but the few genes associated with it explain only a small portion of its variation. Studies of PAI-1 typically employ linear regression to estimate the effects of genetic variants on PAI-1 levels, but PAI-1 is not normally distributed, even after transformation. Therefore, alternative statistical methods may provide greater...

Data from: Emerging Representational Geometries in the Visual System Predict Reaction Times for Object Categorization

J. Brendan Ritchie, David A. Tovar & Thomas A. Carlson
Recognizing an object takes just a fraction of a second, less than the blink of an eye. Applying multivariate pattern analysis, or "brain decoding", methods to magnetoencephalography (MEG) data has allowed researchers to characterize, in high temporal resolution, the emerging representation of objects that underlie our capacity for rapid recognition. Shortly after stimulus onset, exemplar stimuli cluster by category in high-dimensional activation spaces. In these emerging activation spaces, the decodability of exemplar category varies over...

Data from: Bile diversion to the distal small intestine has comparable metabolic benefits to bariatric surgery

Roux-en-Y gastric bypass (RYGB) is highly effective in reversing obesity and associated diabetes. Recent observations in humans suggest a contributing role of increased circulating bile acids in mediating such effects. Here we use a diet-induced obesity (DIO) mouse model and compare metabolic remission when bile flow is diverted through a gallbladder anastomosis to jejunum, ileum or duodenum (sham control). We find that only bile diversion to the ileum results in physiologic changes similar to RYGB,...

Data from: Phylogenetic distribution of symbiotic bacteria from Panamanian amphibians that inhibit growth of the lethal fungal pathogen Batrachochytrium dendrobatidis

Matthew H. Becker, Jenifer B. Walke, Lindsey Murrill, Douglas C. Woodhams, Laura K. Reinert, Louise A. Rollins-Smith, Elizabeth A. Burzynski, Thomas P. Umile, Kevin P. C. Minbiole & Lisa K. Belden
The introduction of next-generation sequencing has allowed for greater understanding of community composition of symbiotic microbial communities. However, determining the function of individual members of these microbial communities still largely relies on culture-based methods. Here, we present results on the phylogenetic distribution of a defensive functional trait of cultured symbiotic bacteria associated with amphibians. Amphibians are host to a diverse community of cutaneous bacteria and some of these bacteria protect their host from the lethal...
