Putative resistance and tolerance mechanisms have little impact on disease progression for an emerging salamander pathogen

Mark Wilber, Edward Carter, Matthew Gray & Cheryl Briggs
1. Resistance and tolerance are unique host defense strategies that can limit the impacts of a pathogen on a host. However, for most wildlife-pathogen systems there are still fundamental uncertainties regarding 1) how changes in resistance and tolerance can affect disease outcomes and 2) the mechanisms underlying resistance and tolerance in host populations. 2. Here, we first compared observed patterns of resistance and tolerance and their effects on disease outcomes among salamander species that are...

Land use impacts on parasitic infection: A cross-sectional epidemiological study on the role of irrigated agriculture in schistosome infection in a dammed landscape

Andrea Lund, David Rehkopf, Susanne Sokolow, M. Moustapha Sam, Nicolas Jouanard, Anne-Marie Schacht, Simon Senghor, Assane Fall, Gilles Riveau, Giulio De Leo & David Lopez-Carr
Background: Water resources development promotes agricultural expansion and food security. But are these benefits offset by increased infectious disease risk? Dam construction on the Senegal River in 1986 was followed by agricultural expansion and increased transmission of human schistosomes. Yet the mechanisms linking these processes at the individual and household levels remain unclear. We investigated the association between household land use and schistosome infection in children. Methods: We analyzed cross-sectional household survey data (n =...

Causes of delayed outbreak responses and their impacts on epidemic spread

Yun Tao, Matthew Ferrari, Katriona Shea, William Probeert, Michael Runge, Kevin Lafferty & Michael Tildesley
Livestock diseases have devastating consequences economically, socially, and politically across the globe. In certain systems, pathogens remain viable after host death, which enables residual transmissions from infected carcasses. Rapid culling and carcass disposal are well-established strategies for stamping out an outbreak and limiting its impact, however, wait-times for these procedures, i.e., response delays, are typically farm-specific and time-varying due to logistical constraints. Failing to incorporate variable response delays in epidemiological models may understate outbreak projections...

Triennial migration and philopatry in the critically endangered soupfin shark (Galeorhinus galeus)

Andrew Nosal, Daniel Cartamil, Arnold Ammann, Lyall Bellquist, Noah Ben-Aderet, Kayla Blincow, Echelle Burns, Eric Chapman, Ryan Freedman, Peter Klimley, Ryan Logan, Christopher Lowe, Brice Semmens, Connor White & Philip Hastings
Globally, one-quarter of shark and ray species is threatened with extinction due to overfishing. Effective conservation and management can facilitate population recoveries; however, these efforts depend on robust data on movement patterns and stock structure, which are lacking for many threatened species, including the Critically Endangered soupfin shark (Galeorhinus galeus), a circumglobal coastal-pelagic species. Using passive acoustic telemetry, we continuously tracked 34 mature female soupfin sharks, surgically implanted with coded acoustic transmitters, for seven years...

Juan José Arreola y su estética del zigzag

Sara Poot Herrera
pp. 77-90 The work of Juan José Arreola, taken as a whole, represents a fluid and continuous coming and going between life and literature, reality and fiction. It is a back and forth trip, a zig zag between official and popular culture, literary genres, orality and writing, because Arreola is above all a thinker and a man of culture through multiple facets that accompanied him throughout his career: essayist, narrator, chronicler, biographer, philologist, teacher, actor,...

Kinetic sequencing (k-Seq) as a massively parallel assay for ribozyme kinetics: utility and critical parameters

Yuning Shen, Abe Pressman, Evan Janzen & Irene Chen
Characterizing genotype-phenotype relationships of biomolecules (e.g., ribozymes) requires accurate ways to measure activity for a large set of molecules. Kinetic measurement using high-throughput sequencing (e.g., k-Seq) is an emerging assay applicable in various domains that potentially scales up measurement throughput to over 106 unique nucleic acid sequences. However, maximizing the return of such assays requires understanding the technical challenges introduced by sequence heterogeneity and DNA sequencing. We characterized the k-Seq method in terms of model...

Protecting the global ocean for biodiversity, food and climate

Enric Sala & Juan Mayorga
The ocean contains unique biodiversity, provides valuable food resources and is a major sink for anthropogenic carbon. Marine protected areas (MPAs) are an effective tool for restoring ocean biodiversity and ecosystem services1,2, but at present only 2.7% of the ocean is highly protected3. This low level of ocean protection is due largely to conflicts with fisheries and other extractive uses. To address this issue, here we developed a conservation planning framework to prioritize highly protected...

A distributed circuit for associating environmental context to motor choice in retrosplenial cortex

Luis Franco & Michael Goard
During navigation, animals often use recognition of familiar environmental contexts to guide motor action selection. The retrosplenial cortex (RSC) receives inputs from both visual cortex and subcortical regions required for spatial memory, and projects to motor planning regions. However, it is not known whether RSC is important for associating familiar environmental contexts with specific motor actions. Here, we test this possibility by developing a task in which trajectories are chosen based on the context. We...

Data From: Tactile Echoes: Multisensory Augmented Reality for the Hand

Anzu Kawazoe, Gregory Reardon, Erin Woo, Massimiliano Di Luca & Yon Visell
Touch interactions are central to many human activities, but there are few technologies for computationally augmenting free-hand interactions with real environments. Here, we describe Tactile Echoes, a finger-wearable system for augmenting touch interactions with physical objects. This system captures and processes touch-elicited vibrations in real-time in order to enliven tactile experiences. We process these signals via a parametric signal processing network in order to generate responsive tactile and auditory feedback. Just as acoustic echoes are...

Data from: A food web including parasites for kelp forests of the Santa Barbara Channel, California

Dana Morton, Cristiana Antonino, Farallon Broughton, Dykman Lauren, Armand Kuris & Kevin Lafferty
We built a high-resolution topological food web for the kelp forests of the Santa Barbara Channel, California, USA that includes parasites and significantly improves resolution compared to previous webs. The 1,098 nodes and 21,956 links in the web describe an economically, socially, and ecologically vital system. Nodes are broken into life-stages. There are 549 free-living life-stages (comprising 492 species from 21 Phyla) and 549 parasitic life-stages (comprising 450 species from 10 Phyla). Links represent three...

The CALFISH database: open-sourcing a century of California’s non-confidential fisheries landings and participation data

Christopher Free, Camila Vargas Poulsen & Lyall Bellquist
California’s commercial and recreational fisheries support vibrant coastal economies and communities. Maintaining healthy fishing communities into the future requires a detailed understanding of their past. The California Department of Fish and Wildlife (CDFW) has been monitoring statewide fisheries landings and participation since 1916 and releases confidential versions of this data through authorized data requests and non-confidential summaries of this data in its quasi-annual landings reports. The non-confidential data published in the landings reports provide a...

Supporting information for: A pilot experiment on infrasonic lahar detection at Mount Adams, Cascades: Ambient infrasound and wind-noise characterization at a quiescent stratovolcano: time-lapse camera images

Richard Sanderson, Robin Matoza, Rachel Haymon & Jamison Steidl
Erosion, hydrothermal activity, and magmatism at volcanoes can cause large and unexpected mass wasting events. Large fluidized debris flows have occurred within the past 6,000 years at Mount Adams, WA, and present a hazard to communities downstream. In August 2017, we began a pilot experiment to investigate the potential of infrasound arrays for detecting and tracking debris flows at Mount Adams. We deployed a telemetered 4-element infrasound array (BEAR, 85-m aperture) ~11 km from a...

Imaging the breakdown of ohmic transport in graphene

Alec Jenkins, Susanne Baumann, Haoxin Zhou, Simon Meynell, Daipeng Yang, Kenji Watanabe, Takashi Taniguchi, Andrew Lucas, Andrea Young & Ania Bleszynski Jayich
Ohm's law describes the proportionality of current density and electric field. In solid-state conductors, Ohm's law emerges due to electron scattering processes that relax the electrical current. Here, we use nitrogen-vacancy center magnetometry to directly image the local breakdown of Ohm's law in a narrow constriction fabricated in a high mobility graphene monolayer. Ohmic flow is visible at room temperature as current concentration on the constriction edges, with flow profiles entirely determined by sample geometry....

Long-term change in the parasite burden of shore crabs (Hemigrapsus oregonensis and H. nudus) on the northwestern Pacific coast of North America

Jessica Quinn, Sarah Lee, Duncan Greeley, Alyssa Gehman, Armand Kuris & Chelsea Wood
The abundances of free-living species have changed dramatically in recent decades, but little is known about change in the abundance of parasitic species. We investigated whether populations of several parasites have shifted over time in two shore crab hosts, Hemigrapsus oregonensis and H. nudus, by comparing the prevalence and abundance of three parasite taxa in a historical dataset (1969–1970) to contemporary parasite abundance (2018–2020) for hosts collected from 11 intertidal sites located from Oregon, USA...

The tribosphenic molar presents phylotypic stage of the mammalian dental evolution. A study of its enamel microarchitecture in several clades (Chiroptera, Afrosoricida, Eulipotyphla, Didelphomorhia, Cetartiodactyla) revealed, apart of considerable taxon-specific variation, a set of structural (i-iii) and developmental (iv-x) characteristics common to all: (i)...

Testing the adaptive value of sporulation in budding yeast using experimental evolution

Kelly Thomasson, Alexander Franks, Henrique Teotonio & Stephen Proulx
Saccharomyces yeast grow through mitotic cell division, converting resources into biomass. When cells experience starvation, sporulation is initiated and meiosis produces haploid cells inside a protective ascus. The protected spore state does not acquire resources and is partially protected from desiccation, heat, and caustic chemicals. Because cells cannot both be protected and acquire resources simultaneously, committing to sporulation represents a trade-off between current and future reproduction. Recent work has suggested that passaging through insect guts...

Supporting information for: Comprehensive high‐precision relocation of seismicity on the Island of Hawai‘i 1986–2018: seismicity animations

Robin Matoza, Paul Okubo & Peter Shearer
Abundant seismicity beneath the the Island of Hawai‘i from mantle depths to the surface plays a central role in understanding how volcanoes work, grow, and evolve at this intraplate oceanic hotspot. We perform systematic waveform cross‐correlation, cluster analysis, and relative relocation of 347,445 events representing 32 years of seismicity on and around the island from 1986 to 2018. We successfully relocate 275,009 (79%) events using ∼1.7 billion differential times (P aicnd S) from ∼128 million...

Which Bank is the \"Central\" Bank? An Application of Markov Theory to the Canadian Large Value Transfer System

Morten Bech, James Chapman & Rod Garrat
We use a method similar to Google's PageRank procedure to rank banks in the Canadian Large Value Transfer System (LVTS). Along the way we obtain estimates of the payment processing speeds for the individual banks. These differences in processing speeds are essential for explaining why observed daily distributions of liquidity differ from the initial distributions, which are determined by the credit limits selected by banks.

Data for: Sex-specific differences in swimming, aerobic metabolism, and recovery from exercise in adult coho salmon (Oncorhynchus kisutch) across ecologically relevant temperatures

Krista Kraskura, Emily Hardison & Erika Eliason
Adult female Pacific salmon can have highermigrationmortality rates thanmales, particularly at warm temperatures. However, the mechanisms underlying this phenomenon remain a mystery. Given the importance of swimming energetics on fitness, we measured critical swim speed, swimming metabolism, cost of transport, aerobic scope (absolute and factorial) and exercise recovery in adult female and male coho salmon (Oncorhynchus kisutch) held for 2 days at 3 environmentally relevant temperatures (9oC, 14oC, 18oC) in fresh water. Critical swimming performance...
