Data from: Competitive history shapes rapid evolution in a seasonal climate

Tess Grainger, Seth Rudman, Paul Schmidt & Jonathan Levine
Eco-evolutionary dynamics will play a critical role in determining species’ fates as climatic conditions change. Unfortunately, we have little understanding of how rapid evolutionary responses to climate play out when species are embedded in the competitive communities that they inhabit in nature. We tested the effects of rapid evolution in response to interspecific competition on subsequent ecological and evolutionary trajectories in a seasonally changing climate using a field-based evolution experiment with Drosophila melanogaster. Populations of...

Human-associated microbiota suppress invading bacteria even under disruption by antibiotics

Andrew Letten, Michael Baumgartner, Katia Pfrunder-Cardozo, Jonathan Levine & Alex Hall
In light of their adverse impacts on resident microbial communities, it is widely predicted that broad-spectrum antibiotics can promote the spread of resistance by releasing resistant strains from competition with other strains and species. We investigated the competitive suppression of a resistant strain of Escherichia coli inoculated into human-associated communities in the presence and absence of the broad and narrow spectrum antibiotics rifampicin and polymyxin B, respectively. We found strong evidence of community-level suppression of...

Biodiversity data from: The mass extinction debt of the Anthropocene

Christopher Spalding & Pincelli Hull
To make sense of our present biodiversity crises, the modern rate of species extinctions is commonly compared to a benchmark, or “background,” rate derived from the fossil record. These estimates are critical for bounding the scale of modern diversity loss, but have yet to account for the fundamental structure of extinction rates through time. Namely, a substantial fraction of extinctions within the fossil record occur within relatively short-lived extinction pulses, and not during intervals characterized...

Data for: 'Facies control on carbonate δ13C on the Great Bahama Bank'

Emily Geyman & Adam Maloof
The carbon isotopic (δ13C) composition of shallow-water carbonates often is interpreted to reflect the δ13C of the global ocean and is used as a proxy for changes in the global carbon cycle. However, local platform processes, in addition to meteoric and marine diagenesis, may decouple carbonate δ13C from that of the global ocean. To shed light on the extent to which changing sediment grain composition may produce δ13C shifts in the stratigraphic record, we present...

Social media and public perception as core aspect of public health: the cautionary case of @realdonaldtrump and COVID19

Jeffrey Peterson & Agustin Fuentes
The social media milieu in which we are enmeshed has substantive impacts on our beliefs and perceptions. Recent work has established that this can play a role in influencing understanding of, and reactions to, public health information. Twitter, in particular, appears to play a substantive role in the public health information ecosystem. From July 25th, 2020 to November 15th, 2020, we collected weekly tweets related to COVID19 keywords and assessed their networks, patterns and properties....

Age-specific habitat preference, carrying capacity, and landscape structure determine the response of population spatial variability to fishing-driven age truncation

Hsiao-Hang Tao, Gaël Dur, Po-Ju Ke, Sami Souissi & Chih-Hao Hsieh
1. Understanding the mechanisms underlying spatial variability of exploited fish is critical for the sustainable management of fish stocks. Empirical studies suggest that size-selective fishing can elevate fish population spatial variability (i.e., more heterogeneous distribution) through age truncation, making the population less resilient to changing environment. However, species differ in how their spatial variability respond to age truncation and the underlying mechanisms remain unclear. 2. We hypothesize that age-specific habitat preference, together with environmental carrying...

Data for: 'How is sea level change encoded in carbonate stratigraphy?'

Emily Geyman, Adam Maloof & Blake Dyer
The history of organismal evolution, seawater chemistry, and paleoclimate is recorded in layers of carbonate sedimentary rock. Meter-scale cyclic stacking patterns in these carbonates often are interpreted as representing sea level change. A reliable sedimentary proxy for eustasy would be profoundly useful for reconstructing paleoclimate, since sea level responds to changes in temperature and ice volume. However, the translation from water depth to carbonate layering has proven difficult, with recent surveys of modern shallow water...

Data from: Host population dynamics in the face of an evolving pathogen

Wesley Hochachka, Andrew Dobson, Dana Hawley & André Dhondt
1. Interactions between hosts and pathogens are dynamic at both ecological and evolutionary levels. In the resultant “eco-evolutionary dynamics” ecological and evolutionary processes affect each other. For example, the house finch (Haemorhous mexicanus) and its recently-emerged pathogen, the bacterium Mycoplasma gallisepticum, form a system in which evidence suggests that changes in bacterial virulence through time enhance levels of host immunity in ways that drive the evolution of virulence in an arms race. 2. We use...

High social status males experience accelerated epigenetic aging in wild baboons

Jordan Anderson, Rachel Johnston, Amanda Lea, Fernando Campos, Tawni Voyles, Mercy Akinyi, Susan Alberts, Elizabeth Archie & Jenny Tung
Aging, for virtually all life, is inescapable. However, within populations, biological aging rates vary. Understanding sources of variation in this process is central to understanding the biodemography of natural populations. We constructed a DNA methylation-based age predictor for an intensively studied wild baboon population in Kenya. Consistent with findings in humans, the resulting “epigenetic clock” closely tracks chronological age, but individuals are predicted to be somewhat older or younger than their known ages. Surprisingly, these...

Glucocorticoid exposure predicts survival in female baboons

Fernando Campos, Elizabeth Archie, Laurence Gesquiere, Jenny Tung, Jeanne Altmann & Susan Alberts
Are differences in HPA axis activation across the adult lifespan linked to differences in survival? This question has been the subject of considerable debate. We analyze the link between survival and fecal glucocorticoid (GC) measures in a wild primate population, leveraging an unusually extensive longitudinal dataset of 14,173 GC measurements from 242 adult female baboons over 1,634 female-years. We document a powerful link between GCs and survival: females with relatively high current GCs or high...

Dynamic plant-soil microbe interactions: the neglected effect of soil conditioning time

Po-Ju Ke, Peter Zee & Tadashi Fukami
Plant-soil feedbacks (PSF) may change in strength over the life of plant individuals as plants continue to modify the soil microbial community. However, the temporal variation in PSF is rarely quantified and its impacts on plant communities remain unknown. Using a chronosequence reconstructed from annual aerial photos of a coastal dune ecosystem, we characterized >20-year changes in soil microbial communities associated with individuals of the four dominant perennial species, one legume and three non-legume. We...

Data from: Concerted evolution reveals co-adapted amino acid substitutions in Na+K+ ATPase of frogs that prey on toxic toads

Shabnam Mohammadi, Lu Yang, Arbel Harpak, Santiago Herrera-Álvarez, María Del Pilar Rodríguez-Ordoñez, Julie Peng, Karen Zhang, Jay Storz, Susanne Dobler, Andrew Crawford & Peter Andolfatto
Gene duplication is an important source of evolutionary innovation, but the functional distinction between duplicates can be opposed by ongoing gene conversion between them. Here we document a tandem duplication of Na+,K+-ATPase subunit α1 (ATP1A1) sharedby frogs in the genus Leptodactylus,a group of species that feeds on toxic toads. One ATP1A1 paralog evolved resistance to toad toxins while the other paralog retained ancestral susceptibility. Frequent non-allelic gene conversion homogenized most of the paralog sequences,yet the...
