Upper Columbia River Steelhead Capture-Recapture-Recovery data (2008-2018)

Quinn Payton & Nathaniel Hostetter
In the Columbia River basin, USA, predation by Caspian terns (Hydroprogne caspia) on U.S. Endangered Species Act (ESA)-listed juvenile salmonids (smolts; Oncorhynchus spp.) has led to predator management actions to reduce predation; however, the assumption that reduced predation translates into greater salmonid survival, either within the life stage where predation occurs or across their lifetime, has remained untested. To address this critical uncertainty, we analyzed a long-term (2008-2018) mark-recapture-recovery dataset of ESA-listed steelhead trout (O....

Colorectal cancer scRNA-seq 10xG-format data matrix

Christopher Lausted, Raymond Yeung, Xiaowei Yan, Neda Jabbari, Qiang Tian, Heidi Kenerson, Changting Meng, Dani Bergey, Venu Pillarisetty, Kevin Sullivan, Priyanka Baloni & Leroy Hood
Metastatic colorectal cancer (CRC) is a major cause of cancer-related death and incidence is rising in the younger population (<50 years). Current chemotherapies can achieve response rates above 50%, but immunotherapies have limited value for patients with microsatellite-stable (MSS) cancers. The present study investigates the impact of chemotherapy on the tumor immune microenvironment. We treat human liver metastases slices with 5-Fluorouracil (5FU) plus either irinotecan or oxaliplatin, then perform single-cell transcriptome analyses. Results from eight...

A laser-microfabricated electrohydrodynamic thruster forcentimeter-scale aerial robots

Hari Krishna Hari Prasad, Ravi Sankar Vaddi, Yogesh Chukewad, Elma Dedic, Igor Novosselov & Sawyer Fuller
To date, insect scale robots capable of controlled flight have used flapping wings for generating lift, but this requires a complex and failure-prone mechanism. A simpler alternative is electrohydrodynamic (EHD) thrust, which requires no moving mechanical parts. In EHD, corona discharge generates a flow of ions in an electric field between two electrodes; the high-velocity ions transfer their kinetic energy to neutral air molecules through collisions, accelerating the gas and creating thrust. We introduce a...

Enemies with benefits: Integrating positive and negative interactions among terrestrial carnivores

Laura Prugh & Kelly Sivy
Interactions among terrestrial carnivores involve a complex interplay of competition, predation, and facilitation via carrion provisioning, and these negative and positive pathways may be closely linked. Here, we developed an integrative framework and synthesized data from 256 studies of intraguild predation, scavenging, kleptoparisitism, and resource availability to examine global patterns of suppression and facilitation. Large carnivores were responsible for one third of mesocarnivore mortality (n = 1,581 individuals), and intraguild mortality rates were superadditive, increasing...

Experimental shifts in exotic flowering phenology produce strong indirect effects on native plant reproductive success

Susan Waters, Janneke Hille Ris Lambers & Wei-Ling Cherry Chen
By causing phenological shifts that vary among species, climate change is altering time envelopes for species interactions, often with unexpected demographic consequences. Indirect interactions, like apparent competition and apparent facilitation, are especially likely to change in duration because they involve multiple interactors, increasing the likelihood of asynchronous phenological shifts by at least one interactor. Thus, we might observe ecological surprises if intermediaries of indirectly interacting species change their mediating behavior. We explored this possibility in...

Vector bionomics and vectorial capacity as emergent properties of mosquito behaviors and ecology

Sean Wu, Penny Hancock, Arnaud Le Menach, Tanya Russell, Thomas Burkot, , Derek Cummings, Kelly Compton, Daniel Citron, John Marshall, Biyonka Liang, Catherine Moyes, Qian Zhang, David Smith, Samson Kiware, Anne Wilson, Thomas Scott, John Henry, Steven Lindsay, Amit Verma & Hector Sanchez C.
Mosquitoes are important vectors for pathogens that infect humans and other vertebrate animals. Some aspects of adult mosquito behavior and mosquito ecology play an important role in determining the capacity of vector populations to transmit pathogens. Here, we re-examine factors affecting the transmission of pathogens by mosquitoes using a new approach. Unlike most previous models, this framework considers the behavioral states and state transitions of adult mosquitoes through a sequence of activity bouts. We developed...

Orthostatic hypotension, dizziness, neurology outcomes, and death in older adults, supplement methods & tables, STROND checklist

Stephen Juraschek, , Oscar L. Lopez, John S Gottdiener, Lewis A Lipsitz, Lewis H. Kuller & Kenneth J Mukamal
Objective To test the hypothesis that orthostatic hypotension (OH) might cause cerebral hypoperfusion and injury, we examined the longitudinal relationship between orthostatic hypotension (OH) or orthostatic symptoms and incident neurologic outcomes in a community population of older adults. Methods Cardiovascular Health Study (CHS) participants (≥65yrs) without dementia or stroke had blood pressure (BP) measured after lying 20-minutes and after standing 3-minutes. Participants reported dizziness immediately upon standing and any dizziness in the past 2wks. OH...

Archive data for: Loss of predation risk from apex predators can exacerbate marine tropicalization caused by extreme climatic events

Robert Nowicki, Jordan Thomson, James Fourqurean, Aaron Wirsing & Michael Heithaus
1. Extreme climatic events (ECEs) and predator removal represent some of the most widespread stressors to ecosystems. Though species interactions can alter ecological effects of climate change (and vice versa), it is less understood whether, when, and how predator removal can interact with ECEs to exacerbate their effects. Understanding the circumstances under which such interactions might occur is critical because predator loss is widespread and ECEs can generate rapid phase shifts in ecosystems which can...

On the cross-population generalizability of gene expression prediction models

Kevin L. Keys, Angel C.Y. Mak, Marquitta J. White, Walter L. Eckalbar, Andrew W. Dahl, Joel Mefford, Anna V. Mikhaylova, María G. Contreras, Jennifer R. Elhawary, Celeste Eng, Donglei Hu, Scott Huntsman, Sam S. Oh, Sandra Salazar, Michael A. Lenoir, Jimmie Chun Ye, Timothy A. Thornton, Noah Zaitlen, Esteban G. Burchard & Christopher R. Gignoux
The genetic control of gene expression is a core component of human physiology. For the past several years, transcriptome-wide association studies have leveraged large datasets of linked genotype and RNA sequencing information to create a powerful gene-based test of association that has been used in dozens of studies. While numerous discoveries have been made, the populations in the training data are overwhelmingly of European descent, and little is known about the generalizability of these models...

Reduction of elevated proton leak rejuvenates mitochondria in the aged cardiomyocyte

Huiliang Zhang, Nathan Alder, Wang Wang, Hazel Szeto, David Marcinek & Peter Rabinovitch
Aging-associated diseases, including cardiac dysfunction, are increasingly common in the population. However, the mechanisms of physiologic aging in general, and cardiac aging in particular, remain poorly understood. Age-related heart impairment is lacking a clinically effective treatment. Using the model of naturally aging mice and rats, we show direct evidence of increased proton leak in the aged heart mitochondria. Moreover, our data suggested ANT1 as the most likely site of mediating increased mitochondrial proton permeability in...

Data from Cretaceous-Paleogene plant extinction and recovery in Patagonia

Elena Stiles, Peter Wilf, Ari Iglesias, María Alejandra Gandolfo & N. Rubén Cúneo
The Cretaceous-Paleogene (K/Pg) extinction appears to have been geographically heterogeneous for some organismal groups. Southern Hemisphere K/Pg palynological records have shown lower extinction and faster recovery than in the Northern Hemisphere, but no comparable, well-constrained Southern Hemisphere macrofloras spanning this interval had been available. Here, macrofloral turnover patterns are addressed for the first time in the Southern Hemisphere, using over 3,500 dicot leaves from the latest Cretaceous (Maastrichtian) and the earliest Paleocene (Danian) of Argentine...

Speciation and gene flow across an elevational gradient in New Guinea kingfishers

Ethan Linck, Benjamin Freeman & John Dumbacher
Closely related species with parapatric elevational ranges are ubiquitous in tropical mountains worldwide. The gradient speciation hypothesis proposes that these series are the result of in situ ecological speciation driven by divergent selection across elevation. Direct tests of this scenario have been hampered by the difficulty inferring the geographic arrangement of populations at the time of divergence. In cichlids, sticklebacks, and Timema stick insects, support for ecological speciation driven by other selective pressures has come...

Tree seedling trait optimization and growth in response to local-scale soil and light variability

Maria Natalia Umaña, Gabriel Arellano, Nathan Swenson & Jenny Zambrano
At local scales, it has been suggested that high levels of resources lead to increased tree growth via trait optimization (highly peaked trait distribution). However, this contrasts with (i) theories that suggest that trait optimization and high growth occur in the most common resource level and (ii) empirical evidence showing that high trait optimization can be also found at low resource levels. This raises the question of how are traits and growth optimized in highly...

The Rhododendron genome and chromosomal organization provide insight into shared whole-genome duplications across the heath family (Ericaceae)

Valerie L. Soza, Dale Lindsley, Adam Waalkes, Elizabeth Ramage, Rupali P. Patwardhan, Joshua N. Burton, Andrew Adey, Akash Kumar, Ruolan Qiu, Jay Shendure & Benjamin Hall
The genus Rhododendron (Ericaceae), which includes horticulturally important plants such as azaleas, is a highly diverse and widely distributed genus of >1,000 species. Here, we report the chromosome-scale de novo assembly and genome annotation of Rhododendron williamsianum as a basis for continued study of this large genus. We created multiple short fragment genomic libraries, which were assembled using ALLPATHS-LG. This was followed by contiguity preserving transposase sequencing (CPT-seq) and fragScaff scaffolding of a large fragment...

Early life exposure to environmental contaminants (BDE-47, TBBPA, and BPS) produced persistent gut dysbiosis in adult male mice

Julia Yue Cui, Matthew Gomez, Alexander Suvorov, Xiaojian Shi, Haiwei Gu & Sridhar Mani
The gut microbiome is a pivotal player in toxicological responses. We investigated the effects of maternal exposure to 3 human health-relevant toxicants (BDE-47, TBBPA, and BPS) on the composition and metabolite levels (bile acids [BAs] and short chain fatty acids [SCFAs]) of the gut microbiome in adult pups. CD-1 mouse dams were orally exposed to vehicle (corn oil, 10ml/kg), BDE-47 (0.2 mg/kg), TBBPA (0.2 mg/kg), or BPS (0.2 mg/kg) once daily from gestational day 8...

The Pacific lamprey genomic divergence, association mapping, temporal Willamette Falls, spatial rangewide datasets

Jon Hess, Jeramiah Smith, Nataliya Timoshevskaya, Cyndi Baker, Christopher Caudill, David Graves, Matthew Keefer, Andrew Kinziger, Mary Moser, Laurie Porter, Greg Silver, Steven Whitlock & Shawn Narum
High rates of dispersal can breakdown coadapted gene complexes. However, concentrated genomic architecture (i.e., genomic islands of divergence) can suppress recombination to allow evolution of local adaptations despite high gene flow. Pacific lamprey (Entosphenus tridentatus) is a highly dispersive anadromous fish. Observed trait diversity and evidence for genetic basis of traits suggests it may be locally adapted. We addressed whether concentrated genomic architecture could influence local adaptation for Pacific lamprey. Using two new whole genome...

Dissociable control of unconditioned responses and associative fear learning by parabrachial CGRP neurons

Anna Bowen, Jane Chen, Y. Waterlily Huang, Nathan Baertsch, Sekun Park & Richard Palmiter
Parabrachial CGRP neurons receive diverse threat-related signals and contribute to multiple phases of adaptive threat responses in mice, with their inactivation attenuating both unconditioned behavioral responses to somatic pain and fear-memory formation. Because CGRPPBN neurons respond broadly to multi-modal threats, it remains unknown how these distinct adaptive processes are individually engaged. We show that while three partially separable subsets of CGRPPBN neurons broadly collateralize to their respective downstream partners, individual projections accomplish distinct functions: hypothalamic...

Data from: Evaluating tooth strontium and barium as indicators of weaning age in Pacific walruses

Casey Clark, Lara Horstmann & Nicole Misarti
A dataset of calcium-normalized 88Sr and 137Ba concentrations from laser ablation transects across the cementum layer of 107 (female: n = 84, male: n = 23) Pacific walrus (Odobenus rosmarus divergens) teeth. Dataset includes spreadsheets containing elapsed time of laser ablation transect in seconds (ElapsedTime_s; laser transect speed = 5μm/s), calcium-normalized strontium concentrations (Sr_ppm_m88; values below limit of detection replaced with 1/2*limit of detection, see methods), and calcium-normalized barium concentrations (Ba_ppm_m137; values below limit of...

Data from: Adaptation via pleiotropy and linkage: association mapping reveals a complex genetic architecture within the stickleback Eda locus

Sophie Archambeault, Luis Bärtschi, Aurélie Merminod & Catherine Peichel
Genomic mapping of the loci associated with phenotypic evolution has revealed genomic “hotspots”, or regions of the genome that control multiple phenotypic traits. This clustering of loci has important implications for the speed and maintenance of adaptation and could be due to pleiotropic effects of a single mutation or tight genetic linkage of multiple causative mutations affecting different traits. The threespine stickleback (Gasterosteus aculeatus) is a powerful model for the study of adaptive evolution because...

Data from: Aridity drives coordinated trait shifts but not decreased trait variance across the geographic range of eight Australian trees

Leander Anderegg, Xingwen Loy, Ian Markham, Christina Elmer, Mark Hovenden, Janneke HilleRisLambers & Margaret Mayfield
Large intraspecific functional trait variation strongly impacts many aspects of communities and ecosystems, and is the medium upon which evolution works. Yet intraspecific trait variation is inconsistent and hard to predict across traits, species, and locations. We measured within-species variation in leaf mass per area (LMA), leaf dry matter content (LDMC), branch wood density (WD), and allocation to stem area vs. leaf area in branches (branch Huber value, HV) across the aridity range of seven...

Genetic structures across a biogeographical barrier reflect dispersal potential of four Southeast Asian mangrove plant species

Alison Wee, Annika Noreen, Junya Ono, Koji Takayama, Prakash Kumar, Hugh Tan, Mohd Saleh, Tadashi Kajita, Edward Webb, Alison K. S. Wee, Annika M. E. Noreen, Prakash P. Kumar, Hugh T. W. Tan, Mohd N. Saleh & Edward L. Webb
Aim Biogeographic barriers restrict the movement of individuals, resulting in population divergence, genetic differentiation, endemism and speciation. Yet, some barriers demonstrate unequal effect across species depending on species dispersal, which manifests in varying genetic structure. We test the hypotheses that the genetic structure of four coastal mangrove species would reflect differences in dispersal potential across the Malay Peninsula, a major biogeographic barrier in the Indo-West Pacific region. Location Twelve sites from the east and west...
