David Gutzler
This file summarizes the data found in RG_obs_PTSWEQ.csv used in the analysis of the contribution of precipitation, temperature, and SWE to the interannual variability of runoff generation in the Rio Grande headwaters.

Evolutionary stasis, ecophenotypy, and environmental controls on ammonite morphology in the Late Cretaceous (Maastrichtian) Western Interior Seaway, USA

James Witts, Neil Landman, Melanie Hopkins & Corinne Myers
We test for the presence of evolutionary stasis in a species of Late Cretaceous ammonoid cephalopod, Hoploscaphites nicolletii, from the North American Western Interior Seaway. A comprehensive dataset of morphological traits was compiled across the entire spatial and temporal range of this species. These were analyzed in conjunction with sedimentologically and geochemically derived palaeoenvironmental conditions hypothesized to apply selective pressures. All changes in shell shape were observed to be ephemeral and reversable, that is, no...

Body temperature, evaporative water loss and resting metabolic rate data for 12 southern African arid-zone passerines

Zenon Czenze, Ryno Kemp, Van Jaarsveld Barry, Marc Freeman, Ben Smit, Blair Wolf & Andrew McKechnie
Surface water is a critical resource for many birds inhabiting arid regions, but the implications of regular drinking and dependence on surface water for the evolution of thermal physiology remain largely unexplored. We hypothesized that avian thermoregulation in the heat has evolved in tandem with the use of surface water and predicted that a) regularly-drinking species have a greater capacity to elevate rates of evaporative water loss (EWL) compared to non-drinking species, and b) heat...

Data from: Changes in the diet and body size of a small herbivorous mammal (Sigmodon hispidus, hispid cotton rat) following the Late Pleistocene megafauna extinction

Catalina P. Tome, Emma A. Elliott Smith, S. Kathleen Lyons, Seth D. Newsome & Felisa A. Smith
The catastrophic loss of large-bodied mammals during the terminal Pleistocene likely led to cascading effects within communities. While the extinction of the top consumers probably expanded the resources available to survivors of all body sizes, little work has focused on the responses of the smallest mammals. Here, we use a detailed fossil record from the southwestern United States to examine the response of the hispid cotton rat (Sigmodon hispidus) to biodiversity loss and climatic change...

Correlates of hybridization in plants

Nora Mitchell, Lesley G. Campbell, Jeffrey R. Ahern, Kellen C. Paine, Aelton B. Giroldo & Kenneth D. Whitney
Hybridization is a biological phenomenon increasingly recognized as an important evolutionary process in both plants and animals, as it is linked to speciation, radiation, extinction, range expansion and invasion, and allows for increased trait diversity in agricultural and horticultural systems. Estimates of hybridization frequency vary across taxonomic groups, and previous work has demonstrated that some plant groups hybridize more frequently than others. Here, we ask on a global scale whether hybridization is linked to any...

Accelerated brain shape evolution is associated with rapid diversification in an avian radiation

Chad Eliason, Jenna McCullough, Michael Andersen & Shannon Hackett
Niche expansion is a critical step in the speciation process. Large brains linked to improved cognitive ability may enable species to expand their niches and forage in new ways, thereby promoting speciation. Despite considerable work on ecological divergence in brain size and its importance in speciation, relatively little is known about how brain shape relates to behavioral, ecological, and taxonomic diversity at macroevolutionary scales. This is due, in part, to inherent challenges with quantifying brain...

Data from: Social selectivity in aging wild chimpanzees

Alexandra Rosati, Lindsey Hagberg, Drew Enigk, Emily Otali, Melissa Emery Thompson, Martin Muller, Richard Wrangham & Zarin Machanda
Humans prioritize close, positive relationships during aging, and socioemotional selectivity theory proposes that this shift causally depend on capacities for thinking about personal future time horizons. To examine this theory, we tested for key elements of human social aging in longitudinal data on wild chimpanzees. Aging male chimpanzees have more mutual friendships characterized by high, equitable investment, whereas younger males have more one-sided relationships. Older males are more likely to be alone, but they also...

The sampling rate is one observation every fifteen minutes (i.e., 96 observations per day). For most customers, the data spans about six years, from July 30, 2013 to December 30, 2019. However, for some customers, the period...

Context-dependent variability in the population prevalence and individual fitness effects of plant-fungal symbiosis

Marion Donald, Teresa Bohner, Kory Kolis, Alan Shadow, Jennifer Rudgers & Tom Miller
1. Heritable symbionts, found within a diverse array of flora and fauna, are often observed at intermediate prevalence within host populations, despite expectations that positive fitness feedbacks should drive beneficial symbionts to fixation. Intermediate prevalence may reflect neutral dynamics of symbionts with weak fitness effects, transient dynamics of symbionts trending toward fixation (or elimination), or a stable intermediate outcome determined by the balance of fitness effects and failed symbiont transmission. Theory suggests these outcomes should...

Elevational niche-shift migration: Why the degree of elevational change matters for the ecology, evolution, and physiology of migratory birds

Jessie Williamson & Christopher Witt
Abstract Elevational migration can be defined as roundtrip seasonal movement that involves upward and downward shifts in elevation. These shifts incur physiological challenges that are proportional to the degree of elevational change. Larger shifts in elevation correspond to larger shifts in partial pressure of oxygen, air density, temperature, and ultraviolet (UV) exposure. Although most avian examples of elevational migration involve subtle shifts that would have minimal impacts on physiology, shifts of any magnitude have previously...

Data from: Mother's social status is associated with child health in a horticulturalist population

Sarah Alami, Christopher Von Rueden, Edmond Seabright, Thomas S. Kraft, Aaron D. Blackwell, Jonathan Stieglitz, Hillard Kaplan & Michael Gurven
High social status is often associated with greater mating opportunities and fertility for men, but do women also obtain fitness benefits of high status? Greater resource access and child survivorship may be principal pathways through which social status increases women’s fitness. Here we examine whether peer-rankings of women’s social status (indicated by political influence, project leadership and respect) positively covaries with child nutritional status and health in a community of Amazonian horticulturalists. We find that...

Patterns, predictors, and consequence of dominance in hybrids

Kenneth Thompson, Mackenzie Urquhart-Cronish, Kenneth D. Whitney, Loren H. Rieseberg & Dolph Schluter
Compared to those of their parents, are the traits of first-generation (F1) hybrids typically intermediate, biased toward one parent, or mismatched for alternative parental phenotypes? And how does hybrid trait expression affect fitness? To address this empirical gap, we compiled data from 198 studies in which traits were measured in a common environment for two parent taxa and their F1 hybrids. We find that individual traits in F1s are, on average, halfway between the parental...

Under the radar: genetic assessment of Rio Grande Shiner (Notropis jemezanus) and Speckled Chub (Macrhybopsis aestivalis), two Rio Grande basin endemic cyprinids that have experienced recent range contractions

Megan Osborne, David Portnoy, Andrew Fields, Kevin Conway, Megan Bean & Christopher Hoagstrom
The Rio Grande drainage of the southwestern United States and Mexico has undergone intense anthropogenic alteration by water diversions, extraction and associated habitat changes. These alterations have disproportionately impacted the pelagic broadcast spawning guild of minnows (pelagophils). Several Rio Grande endemic pelagophils, including the co-occurring Rio Grande Shiner (Notropis jemezanus) and Speckled Chub (Macrhybopsis aestivalis), have experienced dramatic recent range-wide declines yet have slipped under the radar of conservation efforts. The status of N. jemezanus...

Wild at heart: programs to diminish negative ecological and evolutionary effects of conservation hatcheries

Megan Osborne, Thomas Dowling, Thomas Turner & Kim Scribner
Hatchery programs are critical for conservation and management of many imperiled fishes. Most traditional aquaculture programs negatively affect ecological performance, genetic, and phenotypic diversity of hatchery-origin fish compared with wild counterparts. Here, we synthesize outcomes of three conservation programs aimed at enhancing ‘wildness’. Each program focuses on a different species: lake sturgeon, razorback sucker, and Rio Grande silvery minnow. These species differ in key life history traits including size and age at sexual maturity, reproductive...

Girasol, a sky imaging and global solar irradiance dataset

Guillermo Terrén-Serrano, Adnan Bashir, Trilce Estrada & Manel Martínez-Ramón
The energy available in Micro Grid (MG) that is powered by solar energy is tightly related to the weather conditions in the moment of generation. Very short-term forecast of solar irradiance provides the MG with the capability of automatically controlling the dispatch of energy. We propose to achieve this using a data acquisition systems (DAQ) that simultaneously records sky imaging and Global Solar Irradiance (GSI) measurements, with the objective of extracting features from clouds and...

Genomic variation data for the wagtail hybrid zone

Georgy Semenov, Ethan Link, Erik Enbody, Rebecca Harris, David Khaydarov, Per Alström, Leif Andersson & Scott Taylor
Genome-wide variation in introgression rates across hybrid zones offers a powerful opportunity for studying population differentiation. One poorly understood pattern of introgression is the geographic displacement of a trait implicated in lineage divergence from genome-wide population boundaries. While difficult to interpret, this pattern can facilitate the dissection of trait genetic architecture because traits become uncoupled from their ancestral genomic background. We studied an example of trait displacement generated by the introgression of head plumage coloration...

Species asynchrony stabilises productivity under extreme drought across Northern China grasslands

Taofeek O. Muraina, Chong Xu, Qiang Yu, Yadong Yang, Minghui Jing, Xiaotong Jia, , Quockhanh Dam, Alan K. Knapp, Scott L. Collins, Yiqi Luo, Wentao Luo, Xiaoan Zuo, Xiaoping Xin, Xingguo Han & Melinda D. Smith
1. Biodiversity can stabilise productivity through different mechanisms, such as asynchronous species responses to environmental variability and species stability. Global changes, like intensified drought, could negatively affect species richness, species asynchrony, and species stability, but it is unclear how changes in these mechanisms will affect stability of aboveground primary productivity (ANPP) across ecosystems. 2. We studied the effects of a 4-year extreme drought on ANPP stability and the underlying mechanisms (species richness, species asynchrony, and...
