Data: Similar neural and perceptual masking effects of low-power optogenetic stimulation in primate V1

Spencer Chen, Giacomo Benvenuti, Yuzhi Chen, Satwant Kumar, Charu Ramakrishnan, Karl Deisseroth, Wilson Geisler & Eyal Seidemann
Can direct stimulation of primate V1 substitute for a visual stimulus and mimic its perceptual effect? To address this question, we developed an optical-genetic toolkit to “read” neural population responses using widefield calcium imaging, while simultaneously using optogenetics to “write” neural responses into V1 of behaving macaques. We focused on the phenomenon of visual masking, where detection of a dim target is significantly reduced by a co-localized medium-brightness pedestal. Using our toolkit, we tested whether...

CPCP-1: Thermal demagnetization data

Ziaul Haque, John Geissman, Randall Irmis, Paul Olsen, Christophere Lepre, Hesham Buhedma, Ronald Mundil, William Parker, Cornelia Rasmussen & George Gehrels
The Colorado Plateau Coring Project Phase 1 (CPCP-1) acquired three continuous drill cores from Petrified Forest National Park (PFNP), Arizona, U.S.A. Two cores, CPCP-PFNP13-1A and CPCP-PFNP13-2B, hereafter CPCP-1A and CPCP-2B; respectively, intersected the Upper Triassic Chinle Formation, Lower(?)-Middle Triassic Moenkopi Formation (MF) and Permian Coconino Sandstone. We examined CPCP-1A and CPCP-2B cores to construct a high-resolution magnetostratigraphy of Moenkopi Formation strata. These data files contain progressive thermal demagnetization data collected from the specimens from cores...

A new method for integrating ecological niche modeling with phylogenetics to estimate ancestral distributions

Wilson Guillory & Jason Brown
Ancestral range estimation and projection of niche models into the past have both become common in evolutionary studies where the ancient distributions of organisms are in question. However, these methods are hampered by complementary hurdles: discrete characterization of areas in ancestral range estimation can be overly coarse, especially at shallow timescales, and niche model projection neglects evolution. Phylogenetic niche modeling accounts for both of these issues by incorporating knowledge of evolutionary relationships into a characterization...

Aurora kinase A is essential for meiosis in mouse oocytes

Karen Schindler, Cecilia S. Blengini, Patricia Ibrahimian, Michaela Vaskovicova, David Drutovic, Petr Solc & Karen Schindler
The Aurora protein kinases are well-established regulators of spindle building and chromosome segregation in mitotic and meiotic cells. In mouse oocytes, there is significant Aurora kinase A (AURKA) compensatory abilities when the other Aurora kinase homologs are deleted. Whether the other homologs, AURKB or AURKC can compensate for loss of AURKA is not known. Using a conditional mouse oocyte knockout model, we demonstrate that this compensation is not reciprocal because female oocyte-specific knockout mice are...

Varied oxygen simulations with WACCM6 (Proterozoic to pre-industrial atmosphere)

Gregory Cooke, Daniel Marsh, Catherine Walsh, Benjamin Black & Jean-François Lamarque
The history of molecular oxygen (O2) in Earth’s atmosphere is still debated; however, geological evidence supports at least two major episodes where O2 increased by an order of magnitude or more: the Great Oxidation Event (GOE) and the Neoproterozoic Oxidation Event. O2 concentrations have likely fluctuated (between 10−3 and 1.5 times the present atmospheric level) since the GOE ∼ 2.4 Gyr ago, resulting in a time-varying ozone (O3) layer. Using a three-dimensional (3D) chemistry climate...

Access to Multicultural/Multiethnic Grey Literature: A Networked Approach African American Resources

V. Tessa Perry Evans
Multicultural/multiethnic grey literature is a concept first introduced and defined at the GL'95. Multicultural-multiethnic GL, although considered primary resources, have been fragmented and scattered or buried within other reports and documents making them difficult to identify and access. If these materials are to be of any real value, they must be located, organized, and made accessible to the communities they represent as well as to the general public. GL'95 presentations focused on the opportunities presented...

Multicultural and multiethnic grey literature - A Rich Resource : An African-American Perspective

V. Tessa Perry Evans
Grey literature while very useful and extremely valuable, unfortunately, may never find its way into the usual review channels. Quite often it is this body of literature - commissioned reports, theses, publications of political activist groups, associations and organizations' newsletters an pamphlets, and ethnic print and non-print media - that are the most useful in recording the history and culture of peoples who have suffered discrimination and exclusion. The African-American, as well as the Asian...

Security Transaction Taxes and Market Quality

Pomeranets Anna & Daniel G. Weaver
We examine nine changes in the New York State Security Transaction Taxes (STT) between 1932 and 1981. We find that imposing or increasing an STT results in wider bidask spreads, lower volume, and increased price impact of trades. In contrast to theories of STT imposition as a means to reduce volatility, we find no consistent relationship between the level of an STT and volatility. We examine the propensity of traders to switch trading locations to...

Shape of species climate performance curves affects community response to climate change

Juan Bonachela, Michael Burrows & Malin Pinsky
Understanding how community composition is reshaped by changing climate is important for interpreting and predicting patterns of community assembly through time or across space. Community composition often does not perfectly correspond to expectations from current environmental conditions, leading to community-climate mismatches. Here, we combine data analysis and theory development to explore how species climate response curves affect the community response to climate change. We show that strong mismatches between community and climate can appear in...

Truly ubiquitous CRESS DNA viruses scattered across the eukaryotic tree of life

Lele Zhao, Erik Lavington & Siobain Duffy
Until recently, most viruses detected and characterized were of economic significance, associated with agricultural and medical diseases. This was certainly true for the eukaryote-infecting circular Rep (replication-associated protein)-encoding single-stranded DNA (CRESS DNA) viruses, which were thought to be a relatively small group of viruses. With the explosion of metagenomic sequencing over the past decade and increasing use of rolling-circle replication for sequence amplification, scientists have identified and annotated copious numbers of novel CRESS DNA viruses...

Resource availability and heterogeneity shape the self‐organisation of regular spatial patterning

Jessica Castillo Vardaro, Juan A. Bonachela, Christopher C. M. Baker, Malin L. Pinsky, Daniel F. Doak, Robert M. Pringle & Corina E. Tarnita
Explaining large-scale ordered patterns and their effects on ecosystem functioning is a fundamental and controversial challenge in ecology. Here, we coupled empirical and theoretical approaches to explore how competition and spatial heterogeneity govern the regularity of colony dispersion in fungus-farming termites. Individuals from different colonies fought fiercely, and inter-nest distances were greater when nests were large and resources scarce—as expected if competition is strong, large colonies require more resources, and foraging area scales with resource...

Data and code for: Terrestrial eDNA survey outperforms conventional approach for detecting an invasive pest insect within an agricultural ecosystem

Michael Allen, Anne Nielsen, Donnie Peterson & Julie Lockwood
Recent methodological advances permit surveys for terrestrial insects from the direct collection of environmental DNA (eDNA) deposited on vegetation or other surfaces. However, in contrast to well-studied aquatic applications, little is known about how detection rates for such terrestrial eDNA-based surveys compare with conventional survey methods. Lycorma delicatula, the spotted lanternfly, is an emerging invasive insect in eastern North America, and a significant ecological and economic pest of forested and agricultural systems, especially grapes. During...

Network topology and patch connectivity affect dynamics in experimental and model metapopulations

Paulina Arancibia & Peter Morin
Biological populations are rarely isolated in space and instead interact with others via dispersal in metapopulations. Theory predicts that network connectivity patterns can have critical effects on network robustness, as certain topologies, such as scale-free networks, are more tolerant to disturbances than other patterns. However, at present, experimental evidence of how these topologies affect population dynamics in a metapopulation framework is lacking. We used experimental metapopulations of the aquatic protist Paramecium tetraurelia to determine how...

Data from: Genomic signatures of spatially divergent selection at clownfish range margins

Rene Clark, Matthew Aardema, Peter Andolfatto, Paul Barber, Akihisa Hattori, Jennifer Hoey, & Malin Pinsky
Understanding how evolutionary forces interact to drive patterns of selection and distribute genetic variation across a species’ range is of great interest in ecology and evolution, especially in an era of global change. While theory predicts how and when populations at range margins are likely to undergo local adaptation, empirical evidence testing these models remains sparse. Here, we address this knowledge gap by investigating the relationship between selection, gene flow, and genetic drift in the...

Changes in selection pressure can facilitate hybridization during biological invasion in a Cuban lizard

Dan Bock, Simon Baeckens, Jessica Pita-Aquino, Zachary Chejanovski, Sozos Michaelides, Pavitra Muralidhar, Oriol Lapiedra, Sungdae Park, Douglas Menke, Anthony Geneva, Jonathan Losos & Jason Kolbe
Hybridization is among the evolutionary mechanisms most frequently hypothesized to drive the success of invasive species, in part because hybrids are common in invasive populations. One explanation for this pattern is that biological invasions coincide with a change in selection pressures that limit hybridization in the native range. To investigate this possibility, we studied the introduction of the brown anole (Anolis sagrei) in the southeastern United States. We find that native populations are highly genetically...
