Data from: Exploring microbial dark matter to resolve the deep archaeal ancestry of eukaryotes

Jimmy H. Saw, Anja Spang, Katarzyna Zaremba-Niedzwiedzka, Lina Juzokaite, Jeremy A. Dodsworth, Senthil Murugapiran, Dan R. Colman, Cristina Takacs-Vesbach, Brian P. Hedlund, Lionel Guy & Thijs J.G. Ettema
The origin of eukaryotes represents an enigmatic puzzle, which is still lacking a number of essential pieces. Whereas it is currently accepted that the process of eukaryogenesis involved an interplay between a host cell and an alphaproteobacterial endosymbiont, we currently lack detailed information regarding the identity and nature of these players. A number of studies have provided increasing support for the emergence of the eukaryotic host cell from within the archaeal domain of life, displaying...

Data from: Environmental heterogeneity has a weak effect on diversity during community assembly in tallgrass prairie

Sara G. Baer, John M. Blair & Scott L. Collins
Understanding what constrains the persistence of species in communities is at the heart of community assembly theory and its application to conserving and enhancing biodiversity. The “environmental heterogeneity hypothesis” predicts greater species coexistence in habitats with greater resource variability. In the context of community assembly, environmental heterogeneity may influence the variety and strength of abiotic conditions and competitive interactions (environmental filters) to affect the relative abundance of species and biodiversity. We manipulated key resources that...

Data from: Fungal symbionts maintain a rare plant population but demographic advantage drives the dominance of a common host

Yan-Yi Anny Chung, Thomas E. X. Miller, Jennifer A. Rudgers & Tom E. X. Miller
1. A potential driver of species abundance that remains understudied is the interaction between host species and their microbial symbionts. Beneficial symbionts could promote the dominance of common host species by increasing their population growth rates more than they do for rare species, and symbiont benefits could be important for maintaining rare species in communities. Alternatively, intrinsic differences in demography, independent of interactions with symbionts, could be the main driver of species’ relative abundances. 2....

Data from: Convergence in resource use efficiency across trees with differing hydraulic strategies in response to ecosystem precipitation manipulation

Jean-Marc Limousin, Enrico A. Yepez, Nate G. McDowell & William T. Pockman
1. Plants are expected to respond to drought by maximizing the efficiency of the most limiting resource, the water use efficiency (WUE), at the expense of nitrogen and carbon use efficiencies (NUE and CUE). Therefore, plants resource use efficiencies are viewed as indicators of species drought tolerance. 2. We tested these predictions by measuring leaf-level intrinsic WUE (WUEi, the ratio of net assimilation to stomatal conductance), photosynthetic NUE (PNUE, the ratio of daily maximum net...

Data from: Retrospective stable isotope analysis reveals ecosystem responses to river regulation over the last century

Thomas F. Turner, Trevor J. Krabbenhoft, Michael L. Collyer, Corey A. Krabbenhoft, Melanie S. Edwards & Zachary D. Sharp
Disruption of natural flow regimes, nutrient pollution, and other consequences of human population growth and development have impacted most major rivers of the world. Alarming losses of aquatic biodiversity and biotic homogenization coincide with human-caused river alteration, but effects on aquatic ecosystem processes are not as well documented. This is because unaltered systems for comparison are scarce, and some ecosystem-wide effects may take decades to manifest. We evaluated aquatic ecosystem responses to extensive river-floodplain engineering...

Data from: Sizing ocean giants: patterns of intraspecific size variation in marine megafauna

Craig R. McClain, Meghan A. Balk, Mark C. Benfield, Trevor A. Branch, Catherine Chen, James Cosgrove, Alistair D. M. Dove, Leo C. Gaskins, Rebecca Helm, Frederick G. Hochberg, Frank B. Lee, Andrea Marshall, Steven E. McMurray, Caroline Schanche, Shane N. Stone, Andrew D. Thaler & Rebecca R. Helm
What are the greatest sizes that the largest marine megafauna obtain? This is a simple question with a difficult and complex answer. Many of the largest-sized species occur in the world’s oceans. For many of these, rarity, remoteness, and quite simply the logistics of measuring these giants has made obtaining accurate size measurements difficult. Inaccurate reports of maximum sizes run rampant through the scientific literature and popular media. Moreover, how intraspecific variation in the body...

Data from: Cell signaling-based classifier predicts response to induction therapy in elderly patients with acute myeloid leukemia

Alessandra Cesano, Cheryl L. Willman, Kenneth J. Kopecky, Urte Gayko, Santosh Putta, Brent Louie, Matt Westfall, Norman Purvis, David C. Spellmeyer, Carol Marimpietri, Aileen C. Cohen, James Hackett, Jing Shi, Michael G. Walker, Zhuoxin Sun, Elisabeth Paietta, Martin S. Tallman, Larry D. Cripe, Susan Atwater, Frederick R. Appelbaum & Jerald P. Radich
Single-cell network profiling (SCNP) data generated from multi-parametric flow cytometry analysis of bone marrow (BM) and peripheral blood (PB) samples collected from patients >55 years old with non-M3 AML were used to train and validate a diagnostic classifier (DXSCNP) for predicting response to standard induction chemotherapy (complete response [CR] or CR with incomplete hematologic recovery [CRi] versus resistant disease [RD]). SCNP-evaluable patients from four SWOG AML trials were randomized between Training (N = 74 patients...

Data from: Inclusive fitness and differential productivity across the life course determine intergenerational transfers in a small-scale human society

Paul L. Hooper, Michael Gurven, Jeffrey Winking & Hillard S. Kaplan
Transfers of resources between generations are an essential element in current models of human life-history evolution accounting for prolonged development, extended lifespan and menopause. Integrating these models with Hamilton's theory of inclusive fitness, we predict that the interaction of biological kinship with the age-schedule of resource production should be a key driver of intergenerational transfers. In the empirical case of Tsimane’ forager–horticulturalists in Bolivian Amazonia, we provide a detailed characterization of net transfers of food...
