Data from: Drivers and cascading ecological consequences of Gambusia affinis trait variation

Zachary Wood, Laura Lopez, Celia Symons, Rebecca Robinson, Eric Palkovacs & Michael Kinnison
Phenotypic trait differences among populations can shape ecological outcomes for communities and ecosystems. However, few studies have mechanistically linked heritable and plastic components of trait variation to generalizable processes of ecology, such as trophic cascades. Here we assess morphological and behavioral trait variation in nine populations of common-garden reared western mosquitofish (Gambusia affinis) from three distinct ancestral predator environments (three populations per environment), each reared in the presence and absence of predator cues. We then...

One-to-one orthologs between Danaus plexippus and other insect species

Jose Ranz, Pablo Gonzalez & Cei Abreu-Goodger
Ortholog identification was performed between the gene models annotated in Danaus plexippus, Bombyx mori, and Drosophila melanogaster. The D. plexippus sequences are from an assembly obtained from an individual that belonged to a monarch population found in Irapuato, Mexico. 1-to-1 orthologs were delineated as part of an analysis devised to determining the proportion of gene models with homology support in other Lepidoptera and D. melanogaster, and in relation to a previously published gene annotation of...

Plain-text conversions of U.S. Final Environmental Impact Statements from 2013-2020

Tyler Scott, Nicholas Marantz & Nicola Ulibarri
Administrative procedures are intended to increase transparency and help agencies make better decisions. However, these requirements also increase agency workload. Understanding how public agencies satisfy procedural requirements is a critical facet of agency performance. This analysis focuses on the language agencies use in Environmental Impact Statements (EISs) required by the U.S. National Environmental Policy Act (NEPA) – specifically, the reuse of similar text within and between assessments. We synthesize theories of institutional isomorphism and bureaucratic...

A study of gene expression, structure, and contractility of iPSC-Derived Cardiac Myocytes from a family with heart disease due to LMNA mutation

Mehrsa Mehrabi, Tessa A. Morris, Zixuan Cang, Cecilia H. H. Nguyen, Yutong Sha, Mira N. Asad, Nyree Khachikyan, Taylor L. Greene, Danielle M. Becker, Qing Nie, Michael V. Zaragoza & Anna Grosberg
Genetic mutations to the Lamin A/C gene (LMNA) can cause heart disease, but the mechanisms making cardiac tissues uniquely vulnerable to the mutations remain largely unknown. Further, patients with LMNA mutations have highly variable presentation of heart disease progression and type. In vitro patient-specific experiments could provide a powerful platform for studying this phenomenon, but the use of induced pluripotent stem cell-derived cardiomyocytes (iPSC-CM) introduces heterogeneity in maturity and function thus complicating the interpretation of...

Climatic displacement exacerbates the negative impact of drought on plant performance and associated arthropod abundance

Jordan Croy, Jordan Croy, Jessica Pratt, Daniel Sheng & Kailen Mooney
Climate change is acting on species and modifying communities and ecosystems through changes not only with respect to mean abiotic conditions, but also through increases in the frequency and severity of extreme events. Changes in mean aridity associated with climate change can generate ecotype by environment mismatch (i.e., climatic displacement). At the same time, variability around these shifting means is predicted to increase, resulting in more extreme droughts. We characterized the effects of two axes...

Data from: Antibiotics shift the temperature response curve of Escherichia coli growth

Mauricio Cruz-Loya, Elif Tekin, Tina Manzhu Kang, Natalya Cardona, Natalie Lozano-Huntelman, Alejandra Rodríguez-Verdugo, Van Savage & Pamela Yeh
This publication consists of measurements of the temperature response of Escherichia coli growth in the presence of various antibiotic backgrounds. Growth is measured as the optical density of the corresponding bacterial culture 24 hours after inoculation. Two datasets are included in this submission. The first dataset consists of growth measurements of E. coli cultures at varying temperatures in the presence of a fixed concentration of twelve antibiotics (see table below for full list), and all...

Data for: Topological defects produce kinks in biopolymer filament bundles

Qingda Hu, Maximilian Grill, Elliot Botvinick, Wolfgang Wall, Valentin Slepukhin & Alex Levine
Bundles of stiff filaments are ubiquitous in the living world, found both in the cytoskeleton and in the extracellular medium. These bundles are typically held together by smaller cross-linking molecules. We demonstrate, analytically, numerically, and experimentally, that such bundles can be kinked, that is, have localized regions of high curvature that are long-lived metastable states. We propose three possible mechanisms of kink stabilization: a difference in trapped length of the filament segments between two cross-links,...

Untargeted metabolomics molecular features data for plasma of 20 Peromyscus leucopus and 20 Mus musculus treated with LPS or controls

Alan Barbour, Nurul Islam, Ana Milovic & John Belisle
Animals that are competent natural reservoirs of zoonotic diseases commonly suffer little morbidity from the pathogens they persistently harbor. The mechanisms of this infection tolerance and the trade-off costs are poorly understood. We used exposure to a single dose of lipopolysaccharide (LPS) endotoxin as an experimental model of inflammation to compare the responses of the cricentine rodent Peromyscus leucopus, the white-footed deermouse, to that of Mus musculus, the standard laboratory model for pathogenesis studies. Four...

Data from: Analysis of southern California mitigation banks with implications for The Wildlands Conservancy's Sacred Lands Network and Bluff Lake Reserve

Corrina Tapia
I conducted a qualitative analysis of mitigation banks in southern California, and from interviews with nine individuals associated with the banks or with mitigation tools, reveal the overall lack of cohesive understanding of the purpose and integrity of mitigation banks. This reveals the uncertainty in banking but also presents an opportunity to make recommendations on improvements to this prominent tool. This analysis also lends support to The Wildlands Conservancy as they establish their Sacred Lands...

Peromyscus WGCNA supplement

Gabriela Balderrama-Gutierrez, Ana Milovic, Ali Mortazavi & Alan Barbour
P. leucopus also (deer mouse) is a known reservoir for infectious disease such as lyme disease and it is able to survive infections that other rodent models cannot. In this paper we explore P. lecucopus transcriptomic response after LPS stimulus in blood, liver and spleen using RNA-seq and compare it to M. musculus response. When comparing gene response to LPS from different species and tissues, neutrophil associated terms are enriched in the P. leucopus response,...

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...

Invasion and Global Change Meta-analysis Data

Bianca E. Lopez, Jenica M. Allen, Jeffrey S. Dukes, Jonathan Lenoir, Montserat Vila, Dana M. Blumenthal, Evelyn M. Beaury, Emily J. Fusco, Toni Lyn Morelli, Cascade J. B. Sorte & Bethany A. Bradley
We conducted a global meta-analysis to investigate invasions, abiotic global environmental changes, and their combined effects on native species, communities, and ecosystems.We searched the Web of Science Core Collection for articles and reviews that were available in English through September 30, 2020. Search terms were chosen to identify papers reporting impacts of invasions with one of six abiotic global environmental changes (GECs: warming, nitrogen deposition, O2 depletion, drought, CO2 addition, and altered pH). We assessed...

Milkweeds (Asclepias genus) records in the western U.S.

Nalleli Carvajal Acosta
Species distributions are driven by abiotic and biotic factors, but the importance of variation in the availability and quality of critical resources is poorly understood. Disentangling the relative importance of these factors – abiotic environment, availability of critical resources, and resource quality– will be important to modeling species current distributions and responses to projected climate change. We address these questions using species distribution models (SDMs) for the western monarch butterfly population (Danaus plexippus), whose larvae...

Heterogeneity and chemical reactivity of the remote Troposphere defined by aircraft measurements

Hao Guo
The NASA Atmospheric Tomography (ATom) mission built a photochemical climatology of air parcels based on in situ measurements with the NASA DC-8 aircraft along objectively planned profiling transects through the middle of the Pacific and Atlantic Oceans. ATom measured numerous gases and aerosols, particularly the gaseous species driving the chemical budgets of O3 and CH4: i.e., O3, CH4, CO, C2H6, higher alkanes, alkenes, aromatics, NOx, HNO3, HNO4, peroxyacetylnitrate, other organic nitrates, H2O, HCHO, H2O2, and...

Female differential allocation in response to extra-pair offspring and social mate attractiveness

Kerianne Wilson & Nancy Burley
Renewed debate over what benefits females might gain from producing extra-pair offspring emphasizes the possibility that apparent differences in quality between within-pair and extra-pair offspring are confounded by greater maternal investment in extra-pair offspring. Moreover, the attractiveness of a female’s social mate can also influence contributions of both partners to a reproductive attempt. Here we explore the complexities involved in parental investment decisions in response to extra-pair offspring and mate attractiveness with a focus on...

The Space in Between: Overlapping Narratives of Arrival and Departure in Armenian-American Literary and Visual Arts

Talar Chahinian
Having fled Lebanon during the Civil War of 1975-1990, New Jersey-based author, Vehanoush Tekian, the LA-based experimental filmmaker, Hrayr Eulmessekian, and LA-based photographer, Ara Madzounian return to Beirut as a figurative repository of layered trauma. In Tekian’s prose and poetry, Family Tree (1997), Of Nourishment and the Abyss (2000) and Dispersion Poems (2017), in Eulmessekian’s film Bruitage (2006), and in Madzounian’s Birds Nest: A Photographic Essay of Bourj Hammoud (2015), Beirut is presented as an...

Hippocampal ensembles represent sequential relationships among an extended sequence of nonspatial events

Babak Shahbaba, Lingge Li, Forest Agostinelli, Mansi Saraf, Derenik Haghverdian, Gabriel Elias, Pierre Baldi, Norbert Fortin & Keiland Cooper
The hippocampus is critical to the temporal organization of our experiences. Although this fundamental capacity is conserved across modalities and species, its underlying neuronal mechanisms remain unclear. Here we recorded hippocampal activity as rats remembered an extended sequence of nonspatial events and, using novel statistical methods, uncovered new forms of sequential organization in ensemble activity important for order memory judgments. Specifically, we discovered that hippocampal ensembles provide significant temporal coding throughout nonspatial event sequences, differentiate...

Data from: Elucidating mutual mate choice

Nancy Burley & John Martin
Understanding the dynamics of mutual mate choice requires investigation of mate preferences of both sexes using a variety of designs, but fewer studies have focused on male choice in avian models. Here we conducted two experiments on preferences of male zebra finches to study the impact of trial design on results. Experimental design varied in number of trial participants, inclusion of observer (“audience”) males, and housing design for stimulus females. Females were reared on one...

Ionic amplifying circuits inspired by electronics and biology

Zuzanna Siwy, Rachel Lucas, Lane Baker & Chih-Yuan Lin
Integrated circuits are present in all electronic devices, and enable signal amplification, modulation, and relay. Nature uses another type of circuits composed of channels in a cell membrane, which regulate and amplify transport of ions, not electrons and holes as is done in electronic systems. Here we show an abiotic ionic circuit that is inspired by concepts from electronics and biology. The circuit amplifies small ionic signals into ionic outputs, and its operation mimics the...
