Data from: Day/night upper thermal limits differ within Ectatomma ruidum ant colonies

Annika S. Nelson, Trey Scott, Maciej Barczyk, Terrence P. McGlynn, Arian Avalos, Elizabeth Clifton, Amlan Das, Andreia Figueiredo, Laura L. Figueroa, Mark Janowiecki, Sarah Pahlke, Jignasha D. Rana & Sean O'Donnell
In the tropics, daily temperature fluctuations can pose physiological challenges for ectothermic organisms, and upper thermal limits may affect foraging activity over the course of the day. Variation in upper thermal limits can occur among and within species, and for social insects such as ants, within colonies. Within colonies, upper thermal limits may differ among individuals or change for an individual throughout the day. Daytime foragers of the Neotropical ant Ectatomma ruidum have higher critical...

Data from: Little white lies: pericarp color provides insights into the origins and evolution of Southeast Asian weedy rice

Yongxia Cui, Beng Kah Song, Lin-Feng Li, Ya-Ling Li, Zhongyun Huang, Ana L. Caicedo, Yulin Jia & Kenneth M. Olsen
Weedy rice is a conspecific form of cultivated rice (Oryza sativa L.) that infests rice fields and results in severe crop losses. Weed strains in different world regions appear to have originated multiple times from different domesticated and/or wild rice progenitors. In the case of Malaysian weedy rice, a multiple-origin model has been proposed based on neutral markers and analyses of domestication genes for hull color and seed shattering. Here we examined variation in pericarp...

Data from: Evolution of ecological dominance of yeast species in high-sugar environments

Kathryn M. Williams, Ping Liu & Justin C. Fay
In budding yeasts, fermentation in the presence of oxygen evolved around the time of a whole genome duplication (WGD) and is thought to confer dominance in high-sugar environments because ethanol is toxic to many species. While there are many fermentative yeast species, only Saccharomyces cerevisiae consistently dominates wine fermentations. In this study, we use co-culture experiments and intrinsic growth rate assays to examine the relative fitness of non-WGD and WGD yeast species across environments to...

Data from: Size variation, growth strategies and the evolution of modularity in the mammalian skull

Arthur Porto, Leila Teruko Shirai, Felipe Bandoni De Oliveira & Gabriel Marroig
Allometry is a major determinant of within-population patterns of association among traits and, therefore, a major component of morphological integration studies. Even so, the influence of size variation over evolutionary change has been largely unappreciated. Here, we explore the interplay between allometric size variation, modularity, and life history strategies in the skull from representatives of 35 mammalian families. We start by removing size variation from within-species data and analyzing its influence on integration magnitudes, modularity...

Data from: Mental illness, poverty and stigma in India: a case control study

Jean-Francois Trani, Parul Bakhshi, Jill Kuhlberg, Sreelatha S. Venkataraman, Hemalatha Venkataraman, Nagendra N. Mishra, Nora E. Groce, Sushrut Jadhav & Smita Deshpande
Objective: To assess the effect of experienced stigma on depth of multidimensional poverty of persons with severe mental illness (PSMI) in Delhi, India, controlling for gender, age and caste. Design: Matching case (hospital)–control (population) study. Setting: University Hospital (cases) and National Capital Region (controls), India. Participants: A case–control study was conducted from November 2011 to June 2012. 647 cases diagnosed with schizophrenia or affective disorders were recruited and 647 individuals of same age, sex and...

Wild Dictyostelium discoideum social amoebae show plastic responses to the presence of nonrelatives during multicellular development

Suegene Noh, Lauren Christopher, Joan Strassmann & David Queller
When multiple strains of microbes form social groups, such as the multicellular fruiting bodies of Dictyostelium discoideum, conflict can arise regarding cell fate. Both fixed and plastic differences among strains can contribute to cell fate, and plastic responses may be particularly important if social environments frequently change. We used RNA-sequencing and photographic time series analysis to detect possible conflict-induced plastic differences between wild D. discoideum aggregates formed by single strains compared to mixed pairs of...

Genetic drift does not sufficiently explain patterns of electric signal variation among populations of the mormyrid electric fish Paramormyrops kingsleyae

Jason Gallant, Sophie Picq, Joshua H Sperling, Catherine Cheng & Bruce Carlson
Communication signals serve crucial survival and reproductive functions. In Gabon, the widely distributed mormyrid fish Paramormyrops kingsleyae emits an electric organ discharge (EOD) signal with a dual role in communication and electrolocation that exhibits remarkable variation: populations of P. kingsleyae have either biphasic or triphasic EODs, a feature which characterizes interspecific signal diversity among the Paramormyrops genus. We quantified variation in EODs of 327 P. kingsleyae from 9 populations and compared it to genetic variation...

Data from: Detecting sub-micron space weathering effects in lunar grains with synchrotron infrared nanospectroscopy

Kainen Utt, Ryan Ogliore, Hans Bechtel, Jeffrey Gillis-Davis & Brad Jolliff
Space weathering processes induce changes to the physical, chemical, and optical properties of space-exposed soil grains. For the Moon, space weathering causes reddening, darkening, and diminished contrast in reflectance spectra over visible and near-infrared wavelengths. The physical and chemical changes responsible for these optical effects occur on scales below the diffraction limit of traditional far-field spectroscopic techniques. Recently developed super-resolution spectroscopic techniques provide an opportunity to understand better the optical effects of space weathering on...

Habitat structure mediates vulnerability to climate change through its effects on thermoregulatory behavior

Lauren Neel, Michael Logan, Daniel Nicholson, Christina Miller, Albert Chung, Inbar Maayan, Zach Degon, Madeline DuBois, John David Curlis, Q Taylor, Kaitlin Keegan, Owen McMillan, Jonathan Losos & Christian Cox
Tropical ectotherms are thought to be especially vulnerable to climate change because they are thermal specialists, having evolved in aseasonal thermal environments. However, even within the tropics, habitat structure can influence opportunities for behavioral thermoregulation. Open (and edge) habitats likely promote more effective thermoregulation due to the high spatial heterogeneity of the thermal landscape, while forests are thermally homogenous and may constrain opportunities for behavioral buffering of environmental temperatures. Nevertheless, the ways in which behavior...
