The model that includes hydroeconomic optimization for hydropower production in the Stanislaus and Upper San Joaquin River basins in the Central Sierra Nevada, California. The two basins have high elevation reservoirs that are typically operated to maximize revenue from hydropower production. Therefore, to better...

Data from: Identifying genetic variation associated with environmental variation and drought-tolerance phenotypes in ponderosa pine

Mengjun Shu & Emily Moran
Background Genotype-to-environment (G2E) association analysis coupled with genotype-to-phenotype (G2P) association analysis promises exciting advances towards discovering genes responsible for local adaptation. We combine G2E and G2P analysis with gene annotation in Pinus ponderosa (ponderosa pine), an ecologically and economically important conifer that lacks a sequenced genome, to identify genetic variants and gene functions that may be associated with local adaptation to drought. Results We identified SNP markers in 223 genotypes from across the Sierra Nevada...

Find the Food First: An Omnivorous Sensory Morphotype Predates Biomechanical Specialization for Plant Based Diets in Phyllostomid Bats

Ronald Hall
The role of mechanical morphologies in the exploitation of novel niche space is well characterized. However, the role of sensory structures in unlocking new niches is less clear. Here we investigate the relationship between the evolution of sensory structures and diet during the diversification of noctilionoid bats. With a broad range of foraging ecologies and a well-supported phylogeny, noctilionoids constitute an ideal group for studying this relationship. We used diffusible iodine-based contrast enhanced computed tomography...

Near-term modeled forest fire area and fuel aridity projections

John Abatzoglou
Escalating burned area in western US forests has heightened the need to refine near-term forest fire projections. One critical knowledge gap is how fire-fuel feedbacks may constrain such projections. We use both static climate-fire models and dynamic models that incorporate feedbacks to project future western US forest-fire area. Compared to 1991-2020, static models for 2021-2050 project a doubling in forest-fire area, increased year-to-year variability, and increased occurrence of years with forest-fire area exceeding the 2020...

Data from: Rethinking sustainability in seafood: synergies and trade-offs between fisheries and climate change

Brandi McKuin, Jordan Watson, Stephen Stohs & J. Elliott Campbell
In the manuscript entitled, "Rethinking sustainability in seafood: synergies and trade-offs between fisheries and climate change", we quantified the climate forcing per unit fish protein associated with several different U.S. tuna fishing fleets, among the most important capture fisheries by both volume and value. The fishing fleets include the U.S. purse seine that operates in the Western Central Pacific Fisheries Commission convention area, the U.S. North Pacific albacore surface gear (which includes both troll and...

On the social and cognitive dimensions of wicked environmental problems characterized by conceptual and solution uncertainty

Felber J. Arroyave B., Oscar Yandy Romero Goyeneche, Meredith Gore, Gaston Heimeriks, Jeffrey Jenkins & Alexander M. Petersen
We develop a quantitative framework for understanding the class of wicked problems that emerge at the intersections of “natural”, social, and technological complex systems. Wicked problems reflect our incomplete understanding of interdependent global systems and the systemic risk they pose; such problems escape solutions because they are often ill-defined, and thus misidentified and under-appreciated by communities of problem-solvers. While there are well-documented benefits to tackling boundary-crossing problems from various viewpoints, the integration of diverse approaches...

Data for: Rapid alignment updating with Extensiphy

Jasper T. Field
1. High throughput sequencing has become commonplace in evolutionary studies. Large, rapidly collected genomic datasets are used to capture biodiversity and for monitoring global and national scale disease transmission patterns, among many other applications. Updating homologous sequence datasets with new samples is cumbersome, requiring excessive program runtimes and data processing. We describe Extensiphy, a bioinformatics tool to efficiently update multiple sequence alignments with whole-genome short-read data. Extensiphy performs reference based sequence assembly and alignment in...

Yangtze River basin ecological and hydrogeomorphic data relevant to regional hydrologic classification for sustainable dam operation

Britne Clifton, Anna Rallings & Joshua Viers
While some rivers have been modified and regulated for centuries requiring recovery efforts and restoration, other rivers are currently under development and facing the challenges of environmental degradation and loss of ecological functionality. As countries, such as China, expand current infrastructure to develop and construct flood reduction, hydropower, and water storage facilities along their rivers, the threat of detrimental ecological impacts expands too. To address these pressing challenges, this data set was used in the...

Dataset: Charge order textures induced by non-linear couplings in a half-doped manganite

Ismail El Baggari, David Baek, Michael Zachman, Di Lu, Yasuyuki Hikita, Harold Hwang, Elizabeth Nowadnick & Lena Kourkoutis
Raw data associated with publication. The self-organization of strongly interacting electrons into superlattice structures underlies the properties of many quantum materials. How these electrons arrange within the superlattice dictates what symmetries are broken and what ground states are stabilized. Here we show that cryogenic scanning transmission electron microscopy (cryo-STEM) enables direct mapping of local symmetries and order at the intra-unit-cell level in the model charge-ordered system Nd1/2Sr1/2MnO3. In addition to imaging the prototypical site-centered charge...

Energy and water co-benefits from covering canals with solar panels

Brandi McKuin, Andrew Zumkehr, Jenny Ta, Roger Bales, Joshua Viers, Tappan Pathak & J. Elliott Campbell
In the manuscript entitled, "Energy and water co-benefits from covering canals with solar panels", we quantified the evaporation savings and financial performance of over-canal solar in comparison to over-ground solar on land adjacent to canals, using regional-scale hydrologic and cost simulations. We conducted regional hydrologic and techno-economic simulations of solar PV panels covering California’s 6350 km canal network. We examined the net effect on the financial performance of three different solar PV structures at eight...

Color polymorphism is a driver of diversification

Kinsey Brock, Emily Jane McTavish & Danielle Edwards
Color polymorphism – two or more heritable color phenotypes maintained within a single breeding population – is an extreme type of intra-specific diversity widespread across the tree of life. Color polymorphism is hypothesized to be an engine for speciation, where morph loss or divergence between distinct color morphs within a species results in the rapid evolution of new lineages, and thus, color polymorphic lineages are expected to display elevated diversification rates. Multiple species in the...

Comparative molecular analysis of cancer behavior cultured in vitro, in vivo, and ex vivo

Nicholas R. Hum, Aimy Sebastian, Sean F. Gilmore, Wei He, Kelly A. Martin, Aubree Hinckley, Karen R. Dubbin, Monica L. Moya, Elizabeth K. Wheeler, Matthew A. Coleman & Gabriela G. Loots
Current pre-clinical models of cancer fail to recapitulate the cancer cell behavior in primary tumors primarily because of the lack of a deeper understanding of the effects that the microenvironment has on cancer cell phenotype. Transcriptomic profiling of 4T1 murine mammary carcinoma cells from 2D and 3D cultures, subcutaneous or orthotopic allografts (from immunocompetent or immunodeficient mice), as well as ex vivo tumoroids, revealed differences in molecular signatures including altered expression of genes involved in...

Pronghorn (Antilocapra americana) enamel phosphate δ18O values reflect climate seasonality: implications for paleoclimate reconstruction

Danielle Fraser, Mark Clementz, Jeffrey Welker & Sora Kim
Stable oxygen isotope compositions from vertebrate tooth enamel are commonly used as biogeochemical proxies for paleoclimate reconstructions. However, the utility of enamel isotopic values across species varies due to differences in rates of enamel deposition and mineralization as well as sources of ingested water, body water residence times, and species’ physiology. We evaluate the use of stable oxygen isotope compositions from pronghorn (Antilocapra americana Gray, 1866) enamel for the amplitude reconstruction of terrestrial paleoclimate seasonality....

Elucidating gene expression adaptation of phylogenetically divergent coral holobionts under heat stress

Viridiana Avila-Magaña, Bishoy Kamel, Michael DeSalvo, Kelly Gómez-Campo, Susana Enríquez, Hiroaki Kitano, Rori Rohlfs, Roberto Iglesias-Prieto & Mónica Medina
As coral reefs struggle to survive under climate change, it is crucial to know whether they have the capacity to withstand changing conditions, particularly increasing seawater temperatures. Thermal tolerance requires the integrative response of the different components of the coral holobiont (coral host, algal photosymbiont, and associated microbiome). Here, using a controlled thermal stress experiment across three divergent Caribbean coral species, we attempt to dissect holobiont member metatranscriptome responses from coral taxa with different sensitivities...
