Data for: Evaluating the impact of physical frailty during ageing in wild chimpanzees (Pan troglodytes schweinfurthii)

Melissa Emery Thompson, Stephanie Fox, Kris Sabbi, Emily Otali, Nicole Thompson Gonzalez, Martin Muller, Richard Wrangham & Zarin Machanda
While declining physical performance is an expected consequence of aging, human clinical research has placed increasing emphasis on physical frailty as a predictor of death and disability in the elderly. We examined non-invasive measures approximating frailty in a richly-sampled longitudinal dataset on wild chimpanzees. Using urinary creatinine to assess lean body mass, we demonstrated moderate but significant declines in physical condition with age in both sexes. While older chimpanzees spent less of their day in...

Wild chimpanzees exhibit human-like aging of glucocorticoid regulation

Melissa Emery Thompson, Stephanie Fox, Andreas Berghaenel, Kris Sabbi, Sarah Phillips-Garcia, Drew Enigk, Emily Otali, Zarin Machanda, Richard Wrangham & Martin Muller
Cortisol, a key product of the stress response, has critical influences on degenerative aging in humans. In turn, cortisol production is affected by senescence of the hypothalamic-pituitary-adrenal (HPA) axis, leading to progressive dysregulation and increased cortisol exposure. These processes have been studied extensively in industrialized settings, but few comparative data are available from humans and closely-related species living in natural environments, where stressors are very different. Here, we examine age-related changes in urinary cortisol in...

Predicting amphibian intraspecific diversity with machine learning: Challenges and prospects for integrating traits, geography, and genetic data

Lisa Barrow
The growing availability of genetic datasets, in combination with machine learning frameworks, offer great potential to answer long-standing questions in ecology and evolution. One such question has intrigued population geneticists, biogeographers, and conservation biologists: What factors determine intraspecific genetic diversity? This question is challenging to answer because many factors may influence genetic variation, including life history traits, historical influences, and geography, and the relative importance of these factors varies across taxonomic and geographic scales. Furthermore,...

Supporting data for changing climate reallocates the carbon debt of frequent-fire forests

Matthew Hurteau, Marissa Goodwin, Harold Zald & Malcolm North
Ongoing climate change will likely alter the carbon carrying capacity of forests as they adjust to climatic extremes and changing disturbance regimes. Increasing drought frequency and severity are already causing widespread tree mortality events, which can exacerbate the carbon debt that has developed as a result of fire-exclusion. Reducing tree density and surface fuels decreases the risk of high-severity wildfire and may also limit drought-induced mortality by reducing competition. We utilized a long-term thinning and...

Distinguishing between dispersal and vicariance: A novel approach using anti-tropical taxa across the fish Tree of Life

William Ludt & Corinne Myers
Aim: Anti-tropical taxa are species split by the tropics into disjunct northern and southern populations. These distributions occur throughout the Tree of Life, but the mechanisms proposed to drive this pattern are debated and generally fit into two categories: dispersal and vicariance. Here we quantitatively test the prevalence of dispersal and vicariance as plausible drivers of anti-tropical marine distributions using intra-specific anti-tropical marine fishes as a model system. Location: Primarily Indo-Pacific. Major Taxa Studied: Marine...

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...

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...

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...

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...

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...

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...

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: 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...

Data from: Trematode parasites exceed aquatic insect biomass in Oregon stream food webs

Daniel Preston, Tamara Layden, Leah Segui, Landon Falke, Sara Brant & Mark Novak
1) Although parasites are increasingly recognized for their ecosystem roles, it is often assumed that free-living organisms dominate animal biomass in most ecosystems and therefore provide the primary pathways for energy transfer. 2) To examine the contributions of parasites to ecosystem energetics in freshwater streams, we quantified the standing biomass of trematodes and free-living organisms at nine sites in three streams in western Oregon, USA. We then compared rates of biomass flow from snails (Juga...

Comparing Lifeact and Phalloidin for super-resolution imaging of actin in fixed cells

Michael J. Wester, Hanieh Mazloom-Farsibaf, Farzin Farzam, Mohamadreza Fazel, Marjolein B. M. Meddens & Keith A. Lidke
Visualizing actin filaments in fixed cells is of great interest for a variety of topics in cell biology such as cell division, cell movement, and cell signaling. We investigated the possibility of replacing phalloidin, the standard reagent for super-resolution imaging of F-actin in fixed cells, with the actin binding peptide `lifeact’. We compared the labels for use in single molecule based super-resolution microscopy, where AlexaFluor 647 labeled phalloidin was used in a (d)STORM modality and...

A test of island biogeographic theory applied to estimates of gene flow in a Fijian bird is largely consistent with neutral expectations

Ethan Gyllenhaal, Xena Mapel, Alivereti Naikatini, Robert Moyle & Michael Andersen
Islands were key to the development of allopatric speciation theory because they are a natural laboratory of repeated barriers to gene flow caused by open water gaps. Despite their proclivity for promoting divergence, little empirical work has quantified the extent of gene flow among island populations. Following classic island biogeographic theory, two metrics of interest are relative island size and distance. Fiji presents an ideal system for studying these dynamics, with four main islands that...
