Callens, H Conway, Alison Cook, Hugh Corr, D Damaske, V. Damn, Fausto Ferraccioli, Rene Forsberg, S. Fujita, Y. Gim, P. Gogineni, J. Griggs, Richard Hindmarsh, P. Holmlund … & A. Zirizzotti
We present here Bedmap2 (2013), a suite of gridded products describing surface elevation, ice-thickness and the sea floor and subglacial bed elevation of the Antarctic south of 60deg S. We derived these products using data from a variety of sources, including many substantial surveys completed since the original Bedmap compilation (Bedmap1) in 2001. In particular, the Bedmap2 ice thickness grid is made from 25 million measurements, over two orders of magnitude more than were used...

Data for: Thermal vulnerability in a mountain stream network: Temporal, spatial, and biological data

Kyle Leathers, David Herbst, Mohammad Safeeq & Albert Ruhi
As climate change continues to increase air temperature in high-altitude ecosystems, it has become critical to understand the controls and scales of aquatic habitat vulnerability to warming. Here we used a nested array of high-frequency sensors, and advances in time-series models, to examine spatiotemporal variation in thermal vulnerability in a model Sierra Nevada watershed. Stream thermal sensitivity to atmospheric warming fluctuated strongly over the year and peaked in spring and summer—when hot days threaten invertebrate...

Spatial and Social Behavior of Acanthurus triostegus on Moorea (French Polynesia) and Palmyra Atoll (USA), 2017-2018

Ana Sofia Guerra
Human-induced environmental change has directly and indirectly affected ecosystems on a global scale, altering the behavior, ecology, and evolutionary trajectories of various species. Fishing of marine top predators and the cascading effects this may have on marine ecosystems is of critical concern. Predators are thought to be an important reason for why fish form schools, thus, a reduction in predator populations could alter schooling behavior for prey fish. Here, we investigate the indirect effects of...

Burrowing crabs and physical factors hasten marsh recovery at panne edges

Kathryn Beheshti, Charlie Endris, Peter Goodwin, Annabelle Pavlak & Kerstin Wasson
Salt marsh loss is projected to increase as sea-level rise accelerates with global climate change. Salt marsh loss occurs along both lateral creek and channel edges and in the marsh interior, when pannes expand and coalesce. Often, edge loss is attributed to erosive processes whereas dieback in the marsh interior is linked to excessive inundation or deposition of wrack, but remains poorly understood. We conducted a two-year field investigation in a central California estuary to...

Data from: Context-dependent effects of shifting large herbivore assemblages on plant structure and diversity

Devyn Orr, An Bui, Maggie Klope, Michelle Lee, Ian McCullough, Carina Motta, Isabella Mayorga, Kelli Konicek & Hillary Young
Despite wide recognition of the importance of anthropogenically driven changes in large herbivore communities – including both declines in wildlife and increases in livestock – there remain large gaps in our knowledge about the impacts of these changes on plant communities, particularly when combined with concurrent changes in climate. Considering these prominent forms of global change in tandem enables us to better understand controls on savanna vegetation structure and diversity under real-world conditions.We conducted a...

Quantifying within-species trait variation in space and time reveals limits to trait-mediated drought response

Kelly Kerr, Leander Anderegg, Nicole Zenes & William Anderegg
Climate change is stressing many forests around the globe, yet some tree species may be able to persist through acclimation and adaptation to new environmental conditions. The ability of a tree to acclimate during its lifetime through changes in physiology and functional traits, defined here as its acclimation potential, is not well known. We investigated the acclimation potential of trembling aspen (Populus tremuloides) and ponderosa pine (Pinus ponderosa) trees by examining within-species variation in drought...

Post-fire debris flows: leveraging science for environmental management and community resiliency - Bren Master's group project (sedimetrics)

Quinlan Smith
The movement of soil particles and rocks down hillslopes has affected the southern Santa Barbara County foothills over millions of years. The landscape has been shaped by the periodic cascades of soil debris in Santa Barbara County watersheds. Sediment transport from higher elevations to lower elevations, driven by gravity, can be exacerbated by soil cohesion, rainfall intensity, wildfire, and topographical relief. The combination of these factors influences the overall volume of sediment transported. Predicting the...

Extracellular Recordings from Human Brain Organoids Using High-density CMOS Arrays

Tal Sharf
Human brain organoids replicate much of the cellular diversity and developmental anatomy of the human brain. However, the physiological behavior of neuronal circuits within organoids remains relatively under-explored. With high-density CMOS microelectrode arrays (26,400 electrodes) and shank electrodes (960 electrodes), we probed broadband and three-dimensional extracellular field recordings generated by spontaneous activity of human brain organoids. These recordings simultaneously captured local field potentials (LFPs) and single-unit activity extracted through spike sorting. From spiking activity, we...

Value of information (VOI) for shellfish aquaculture in British Columbia

Emiliano Espinoza
Shellfish aquaculture will play a critical role in meeting the growing demand for protein with low ecosystem impact and carbon intensity. Regions that have experienced inhibited growth in their shellfish aquaculture industries, such as British Columbia, must invest in technical and community-driven solutions to overcome industry barriers. A key barrier to British Columbia’s growth is environmental uncertainty, which impedes optimal farm management and increases the investment risk of shellfish farms. To reduce environmental uncertainty, shellfish...

Indonesia makes progress towards zero palm oil deforestation

Robert Heilmayr & Jason Benedict
Indonesian deforestation for palm oil has declined significantly, with the greatest falls occurring in supply chains governed by zero-deforestation commitments. However, rising palm oil prices and the growing role of traders who have lower levels of public transparency threaten to undermine progress.

Data For: Herbarium specimens provide reliable estimates of phenological responsiveness to climate at unparalleled taxonomic and spatiotemporal scales

Tadeo Ramirez-Parada, Isaac Park & Susan Mazer
Understanding the effects of climate change on the phenological structure of plant communities will require measuring variation in sensitivity among thousands of co-occurring species across regions. Herbarium collections provide vast resources with which to do this, but may also exhibit biases as sources of phenological data. Despite general recognition of these caveats, validation of herbarium-based estimates of phenological sensitivity against estimates obtained using field observations remain rare and limited in scope. Here, we leveraged extensive...

Western Gull movement and nutrient deposition on Channel Islands, CA

Ana Sofia Guerra, Devyn A. Orr, An Bui, Maggie Klope, Hillary S. Young & Scott A. Shaffer
This data package includes data on the foraging-associated movement and nutrient deposition of large nesting colonies of Western Gulls (Larus occidentalis), a generalist carnivore known to forage on human refuse. The study took place on the Channel Islands of California. Specifically, we equipped gulls with GPS loggers to assess the frequency of urban foraging alongside bird density data to estimate wild and urban-derived guano deposition on the island sites. We also conducted nest counts and...

Dataset for: Heat Transfer and Production in Cratonic Continental Crust: Constraints from U-Pb Thermochronology of Xenoliths from the Siberian Craton

Francisco Apen
Coupled U-Pb and trace-element analyses of accessory phases in crustal xenoliths from the Late Devonian Udachnaya kimberlite (Siberian craton, Russia) are used to constrain Moho temperature and crustal heat production at the time of kimberlite eruption. Rutile and apatite in lower-crustal garnet granulites record U-Pb dates that extend from 1.8 Ga to 360 Ma (timing of kimberlite eruption). This contrasts with upper-crustal tonalites and amphibolites that contain solely Paleoproterozoic apatite. Depth profiling of rutile from...

Morphodynamic atlas for Drosophila development

Noah Mitchell, Matthew Lefebvre, Vishank Jain-Sharma, Nikolas Claussen, Marion Raich, Hannah Gustafson, Andreas Bausch & Sebastian Streichan
During morphogenesis, diverse cell-scale and tissue-scale processes couple to dynamically sculpt organs. In this coupling, genetic expression patterns and biochemical signals regulate and respond to mechanical deformations to ensure reproducible and robust changes in tissue geometry. A long-standing approach to characterize these interactions has been the construction of expression atlases, and these atlases have necessarily relied on fixed snapshots of embryogenesis. Addressing how expression profiles relate to tissue dynamics, however, requires a scheme for spatiotemporal...

La traición como una síntesis dialéctica negativa en El apando de José Revueltas y Felipe Cazals

Yunuen Gómez Ocampo
pp. 118-130. The short novel El Apando by Mexican writer José Revueltas, and its film adaptation by Felipe Cazals, very closely share aesthetic and ethical stances. The former serves as the plot basis for the latter, while the latter is the visual and explosive representation of the former. Both works communicate with each other naturally, expressing the anxiety of human existence. In this paper, I analyze two symbolic elements –strongly visual– that, through the plot,...

Does scent attractiveness reveal women’s ovulatory timing? Evidence from signal detection analyses and endocrine predictors of odor attractiveness

James Roney, Mei Mei, Rachel Grillot, Craig Abbey, Melissa Emery Thompson & James Roney
Odor cues associated with shifts in ovarian hormones indicate ovulatory timing in females of many nonhuman species. Although prior evidence supports women’s body odors smelling more attractive on days when conception is possible, that research has left ambiguous how diagnostic of ovulatory timing odor cues are, as well as whether shifts in odor attractiveness are correlated with shifts in ovarian hormones. Here, 46 women each provided 6 overnight scent and corresponding day saliva samples spaced...

Data for: Evaluating conditions for MFAD fisheries development in the Caribbean and Bermuda

Margaret Wilson, Julia Lawson, Maria Ignacia Rivera-Hechem, Juan Carlos Villaseñor-Derbez & Steve Gaines
Moored fish aggregating devices (MFADs) are promoted in small-scale fisheries around the world as tools to increase fisher incomes, enhance food security, and ease pressure on degraded inshore fisheries. Despite their growing popularity, the biophysical and socioeconomic contexts in which MFAD fisheries are implemented - and the implications of these contexts for MFAD fishery success - remain poorly understood. Here we develop a framework identifying and evaluating factors likely to influence MFAD fishery outcomes and...

Global reference histograms of the IMS infrasound broadband detection lists

Samuel Kristoffersen, Alexis Le Pichon, Patrick Hupe & Robin Matoza
This data set builds upon the broadband detection lists of the International Monitoring System (IMS)’s infrasound stations. The infrasound data of these stations are regularly (re-)processed at the German National Data Centre at BGR (e.g., Ceranna et al., 2019; https://doi.org/10.1007/978-3-319-75140-5_13) using the Progressive Multi-Channel Correlation (PMCC) array processing method (Cansi, 1995; https://doi.org/10.1029/95GL00468). The latest reprocessing with 26 one-third octave spaced frequency bands in the IMS band of interest (0.01 to 4 Hz) included all 53...

Multi-modal dataset of a polycrystalline metallic material: 3D microstructure and deformation fields

J.C. Stinville, J.M. Hestroffer, M.A. Charpagne, A.T. Polonsky, M.P. Echlin, C.J. Torbet, V. Valle, A. Loghin, O. Klaas, M.P. Miller, K.E. Nygren, I.J Beyerlein & T.M. Pollock
The development of high-fidelity mechanical property prediction models for the design of polycrystalline materials relies on large volumes of microstructural feature data. Concurrently, at these same scales, the deformation fields that develop during mechanical loading can be highly heterogeneous. Spatially correlated measurements of 3D microstructure and the ensuing deformation fields at the micro-scale would provide highly valuable insight into the relationship between microstructure and macroscopic mechanical response. They would also provide direct validation for numerical...

16S rRNA data for an in vitro model of the human dental plaque bacterial community (3 hosts)

Baoqing Zhou, Jennifer Mobberley, Kelly Shi & Irene Chen
The creation of oral microcosms with reproducible composition is important for developing model systems of the oral microbiome. Here, we report on the outcome of a methodologically simple but scientifically informative approach, in which we sample the dental plaque microbiome from 3 individuals and characterize the variability among the microbiomes after storage and subsequent propagation. We use 24-well culture plates with artificially generated pellicle under a defined anaerobic atmosphere and an undefined medium supplemented by...

The relative strength of selection on modifiers of genetic architecture under migration load

Stephen Proulx & Henrique Teotonio
Gene flow between populations adapting to differing local environmental conditions creates a "migration load" because individuals might disperse to habitats where their survival is low or because they might reproduce with locally maladapted individuals. The amount by which the mean relative population fitness is kept below one creates an opportunity for modifiers of the genetic architecture to spread due to selection. Prior work that separately considered modifiers changing dispersal or recombination rates, or altering dominance...
