ISIMIP3a reservoirs & dams input data

María del Rocío Rivas López, Jida Wang & Fangfang Yao
The Inter-Sectoral Impact Model Intercomparison Project (ISIMIP) provides a framework for the collation of a consistent set of climate impact data across sectors and scales. It also provides a unique opportunity for considering interactions between climate change impacts across sectors through consistent scenarios.
The ISIMIP3a part of the third simulation round is dedicated to i) impact model evaluation and improvement and ii) detection and attribution of observed impacts according to the framework of IPCC AR5 Working...

Positive interactions between an exotic invader and moss biocrusts vary across life-stage and correspond with the effect of water pulses on soil nitrogen

Mandy Slate, Morgan McLeod & Ragan Callaway
The size and frequency of resource pulses can affect plant interactions and increase the abundance of invasive species relative to native species. We examined resource pulses generated during desiccation and rehydration of communities of native biological soil crust (biocrust) forming mosses, in the context of positive associations between biocrusts and the invasive forb, Centaurea stoebe. We surveyed Centaurea and biocrust cover and evaluated how interactions among Centaurea, biocrusts, and water pulses influenced plant biomass and...

Biodiversity-productivity relationships are key to nature-based climate solutions

Akira Mori, Laura Dee, Andrew Gonzalez, Haruka Ohashi, Jane Cowles, Alexandra Wright, Michel Loreau, Yann Hautier, Tim Newbold, Peter Reich, Tetsuya Matsui, Wataru Takeuchi, Kei-Ichi Okada, Rupert Seidl & Forest Isbell
The global impacts of biodiversity loss and climate change are interlinked but the feedbacks between them are rarely assessed. Areas with greater tree diversity tend to be more productive, providing a greater carbon sink, and biodiversity loss could reduce these natural C sinks. Here, we quantify how tree and shrub species richness could affect biomass production at biome, national and regional scales. We find that greenhouse gas mitigation could help maintain tree diversity and thereby...

Fire emissions data before and after peatland restoration, Indonesia, 2004-2015

This dataset contains fire emissions from Equatorial Asia for the years 2004, 2006, 2009, 2012, 2014 and 2015. The data is based on the Fire Inventory from National Center for Atmospheric Research with the addition of emissions from Indonesian peat fires, which contribute substantially to fire emissions in the region. The files for each year contain daily information on the area burned and emissions of several species, including CO, CO2 and PM2.5. Data is given...

The effects of ENSO and the North American monsoon on mast seeding in two Rocky Mountain conifer species

Andreas Wion, Ian Pearse, Kyle Rodman, Thomas Veblen & Miranda Redmond
We aimed to disentangle the patterns of synchronous and variable cone production (i.e., masting) and its relationship to climate in two conifer species native to dry forests of western North America. We used cone abscission scars to reconstruct ca. 15 years of recent cone production in Pinus edulis and Pinus ponderosa, and used redundancy analysis to relate time series of annual cone production to climate indices describing the North American monsoon and the El Niño...

Assessment of biogeographic variation in traits of Lewis flax (Linum lewisii) for use in restoration and agriculture

Peter Innes, André Gossweiler, Scott Jensen, Derek Tilley, Loren St. John, Thomas Jones, Stanley Kitchen & Brent S. Hulke
Lewis flax (Linum lewisii) is widely distributed across western North America and is currently used in native ecosystem restoration. There is also growing interest in de novo domestication of Lewis flax as a perennial oilseed crop. To better understand this species and facilitate both restoration and domestication, we used common gardens to assess bio-geographical variation in a variety of seed and growth traits from 37 flax accessions, consisting of 35 wild populations from the Intermountain...

FIRED URUGUAY

Adam L. Mahood, Jennifer K. Balch, Joe McGlinchy, Estelle J. Lindrooth, Lise A. St. Denis, Maxwell C. Cook, Travis Williams & Nathan P. Mietkiewicz
This is event- and daily-level polygons for the Fire event delineation (FIRED) product for Uruguay from November 2001 to May 2021. It is derived from the MODIS MCD64A1 burned area product (see https://lpdaac.usgs.gov/products/mcd64a1v006/ for more details). The MCD64A1 is a monthly raster grid of estimated burned dates. Firedpy (www.github.com/earthlab/firedpy) is an algorithm that converts these rasters into events by stacking the entire time series into a spatial-temporal data cube, then uses an algorithm to assign...

Data from: Use of an exotic host plant shifts immunity, chemical defense, and viral burden in wild populations of a specialist insect herbivore

Nadya D. Muchoney, M. Deane Bowers, Adrian L. Carper, Peri A. Mason, Mike B. Teglas & Angela M. Smilanich
Defense against natural enemies constitutes an important driver of herbivore host range evolution in the wild. Populations of the Baltimore checkerspot butterfly, Euphydryas phaeton (Nymphalidae), have recently incorporated an exotic plant, Plantago lanceolata (Plantaginaceae), into their dietary range. To understand the tritrophic consequences of utilizing this exotic host plant, we examined immune performance, chemical defense, and interactions with a natural entomopathogen (Junonia coenia densovirus, Parvoviridae) across wild populations of this specialist herbivore. We measured three...

Memory array locations, delay times, and participant response

Kyra Schapiro, Kresimir Josic, Joshua Gold & Zachary Kilpatrick
Deliberative decisions based on an accumulation of evidence over time depend on working-memory, and working memory has limitations, but how these limitations affect deliberative decision-making is not understood. We used human psychophysics to assess the impact of working-memory limitations on the fidelity of a continuous decision variable. Participants decided the average location of multiple visual targets. This computed, continuous decision variable degraded with time and capacity in a manner that depended critically on the strategy...

Magnetospheric substorm effects on equatorial ionosphere

Luis Navarro
Geomagnetic storm ionospheric electrodynamics at the magentic equator are examined in detail using upgraded, higher time resolution, Jicamarca incoherent scatter radar drift observations, SuperMAG geomagnetic field, and solar wind data to study equatorial ionospheric electric fields during the 8 September 2017 storm main and early recovery phases. We show that during a period of moslty large and southward IMF Bz there were numerous daytime prompt penetration vertical and zonal plasma drifts. These prompt penetration events...

Data from: Rocky Mountain forests are poised to recover following bark beetle outbreaks, but with altered composition

Kyle Rodman, Robert Andrus, Amanda Carlson, Trevor Carter, Teresa Chapman, Jonathan Coop, Paula Fornwalt, Nathan Gill, Brian Harvey, Ashley Hoffman, Katharine Kelsey, Dominik Kulakowski, Daniel Laughlin, Jenna Morris, José Negrón, Katherine Nigro, Gregory Pappas, Miranda Redmond, Charles Rhoades, Monique Rocca, Zoe Schapira, Jason Sibold, Camille Stevens-Rumann, Thomas Veblen, Jianmin Wang … & Sarah Hart
Amplified by warming temperatures and drought, recent outbreaks of native bark beetles (Curculionidae: Scolytinae) have caused extensive tree mortality throughout Europe and North America. Despite their ubiquitous nature and important effects on ecosystems, forest recovery following such disturbances is poorly understood, particularly across regions with varying abiotic conditions and outbreak effects. To better understand post-outbreak recovery across a topographically complex region, we synthesized data from 16 field studies spanning subalpine forests in the Southern Rocky...

Planetary core-style rotating convective flows in paraboloidal laboratory experiments

Taylor Lonner, Ashna Aggarwal & Jonathan Aurnou
Turbulent convection in a planet’s outer core is simulated here using a thermally-driven free surface paraboloidal laboratory annulus. We show that the rapidly rotating convection dynamics in free-surface paraboloidal annuli are similar to those in planetary spherical shell geometries. Three experimental cases are carried out, respectively, at 35 revolutions per minute (rpm), 50 rpm and 60 rpm.Thermal Rossby waves are detected in full disk thermographic images of the fluid’s free surface. Ultrasonic flow velocity measurements...

Global Scale Wave Model 2009 (GSWM-09)

Jeffrey Forbes & Xiaoli Zhang
GSWM-09 results provide the most recent comprehensive set of GSWM outputs that provide amplitudes and phases (UT of maximum at 0º longitude) of solar diurnal and semidiurnal tidal wind and temperature perturbations in Earth's atmosphere from pole to pole and from the ground to 245 km altitude. Their value lies in the use of realistic observational and empirical model data to specify the tropospheric and stratospheric forcing of the full spectrum of solarsynchronous ("migrating" with...

Disturbance-mediated hybridization in black-capped and mountain chickadees

Kathryn Grabenstein
Human habitat disturbances can promote hybridization between closely related, but typically reproductively isolated, species. We explored whether human habitat disturbances are related to hybridization between two closely related songbirds, black-capped, and mountain chickadees, using both genomic and citizen science datasets. First, we genotyped 409 individuals from across both species’ ranges using reduced-representation genome sequencing and compared measures of genetic admixture to a composite measure of human landscape disturbance. Then, using eBird observations, we compared human...
