Quantifying microburst wind and turbulence enhancement in canyons

Katja Friedrich & Luchetti Nicholas
This data set contains model output from NCARS's Weather and Research Forecasting(WRF) model run in large-eddy simulation (LES) mode (WRF v3.6). A series of idealized simulations were conducted with the center of microburst downdrafts were placed 1.3 and 3.3 km upwind of a series of canyon types differing in length and slope angle. These canyon simulations are compared to microburst outflow boundary characteristics in flat terrain deriving topographic multiplier and differences in horizontal winds (wsp),...

Data for: Dorsal premammillary projection to periaqueductal gray controls escape vigor from innate and conditioned threats

Peter Schuette, Weisheng Wang, Mimi La-Vu, Brooke Tobias, Marta Ceko, Philip Kragel, Fernando Reis, Shiyu Ji, Megha Sehgal, Sandra Maesta-Pereira, Meghmik Chakerian, Alcino Silva, Newton Canteras, Tor Wager, Jonathan Kao & Avishek Adhikari
Escape from threats has paramount importance for survival. However, it is unknown if a single circuit controls escape from innate and conditioned threats. The hypothalamic dorsal premammillary nucleus (PMd) may control escape, as it is strongly activated by escape-inducing threats and projects to the region most implicated in escape, the dorsolateral periaqueductal gray (dlPAG). We show that in mice cholecystokinin (cck)-expressing PMd cells are activated during escape, but not other defensive behaviors. PMd-cck ensemble activity...

Host controls of within-host disease dynamics: insight from an invertebrate system

Tara Stewart Merrill, Zoi Rapti & Carla Cáceres
Within-host processes (representing the entry, establishment, growth and development of a parasite inside its host) may play a key role in parasite transmission but remain challenging to observe and quantify. We develop a general model for measuring host defenses and within-host disease dynamics. Our stochastic model breaks the infection process down into the stages of parasite exposure, entry, and establishment and provides associated probabilities for a host’s ability to resist infections with barriers and clear...

Dispersers and environment drive global variation in fruit color syndromes

Miranda Sinnott-Armstrong, Michael Donoghue & Walter Jetz
The colors of fleshy fruits play a critical role in plant dispersal by advertising ripe fruits to consumers. Fruit colors have long been classified into syndromes attributed to selection by animal dispersers, despite weak evidence for this hypothesis. Here, we test the relative importance of biotic (bird and mammal frugivory) and abiotic (wet season temperatures, growing season length, and UV-B radiation) factors in determining fruit color syndrome in 3,163 species of fleshy-fruited plants. We find...

Plant-pollinator interactions between generalists persist over time and space

Julian Resasco, Natacha Chacoff & Diego Vázquez
Generalist species are the linchpins of networks, as they are important for maintaining network structure and function. Previous studies have shown that interactions between generalists tend to occur consistently across years and sites. However, the link between temporal and spatial interaction persistence across scales remains unclear. To address this gap, we collected data on plant-pollinator interactions throughout the flowering period for five years across six plots in a subalpine meadow in the Rocky Mountains. We...

Data from: Water the odds? Spring rainfall and emergence-related seed traits drive plant recruitment

Julie Larson, Kathleen Ebinger & Katharine Suding
Recruitment of new individuals from seed is a critical component of plant community assembly and reassembly, especially in the context of ecosystem disturbance and recovery. While frameworks typically aim to predict how communities will be filtered on the basis of traits influencing established plant responses to the environment, assembly from seed is more complex: the responses of seeds (affected by dormancy and germination function) and establishing plants (affected by root and leaf function) can both...

A highly invasive malaria parasite has expanded its range to non-migratory birds in North America

Angela Theodosopoulos, Kathryn Grabenstein, Staffan Bensch & Scott Taylor
Parasite range expansions are a direct consequence of globalization and are an increasing threat to biodiversity. Here we report a recent range expansion of the SGS1 strain of a highly invasive parasite, Plasmodium relictum, to two non-migratory passerines in North America. Plasmodium relictum is considered one of the world’s most invasive parasites and causes the disease avian malaria: this is the first reported case of SGS1 in wild birds of Western North America and wild...

Data from: Multiple dimensions of bird beta diversity support that mountains are higher in the tropics

Flavia A. Montaño-Centellas, Bette Loiselle & Christy McCain
Aim We examine latitudinal effects of breeding bird taxonomic, phylogenetic and functional β-diversity (Tβ, Pβ and Fβ, respectively) along elevational gradients to test predictions derived from Janzen’s (1967) classic ideas that tropical mountains represent stronger dispersal barriers than temperate mountains. Location Global Taxon Birds Methods Using a global dataset from 46 mountains, we examine latitudinal patterns of Tβ, Pβ, and Fβ, and their components: β rich and β repl. For each mountain and each dimension...

Why do parasites exhibit reverse latitudinal diversity gradients? Testing the roles of host diversity, habitat, and climate

Pieter Johnson & Sarah Haas
Aim: The latitudinal diversity gradient (LDG) – in which species richness decreases from the equator toward the poles – is among the most fundamental distributional patterns in ecology. Despite the expectation that the diversity of parasites tracks that of their hosts, available evidence suggests that many parasites exhibit reverse latitudinal gradients or no pattern, yet the rarity of large-scale datasets on host-parasite interactions calls into question the robustness of such trends. Here, we collected parasitological...

The PDS website doesn't contain data for nightside observations whereas this data set is explicitly from nightside observation used in the aurora study that has been submitted (soon to be published) to ascientific journal. Detail of the data structure can be...

Ultra-sensitive multi-species spectroscopic breath analysis for real-time health monitoring and diagnostics

Ya-Chu Chan, Jun Ye, Qizhong Liang, Jutta Toscano, P. Bryan Changala & David J. Nesbitt
Abstract from associated manuscript: Abstract from the manuscript: Breath analysis enables rapid, non-invasive diagnostics, as well as long-term monitoring, of human health through the identification and quantification of exhaled biomarkers. Here, for the first time, we demonstrate the remarkable capabilities of mid-infrared (mid-IR) cavity-enhanced direct frequency comb spectroscopy (CE-DFCS) applied to breath analysis. We simultaneously detect and monitor as a function of time four breath biomarkers - CH3OH, CH4, H2O and HDO - as well...

Divergent sexual signals reflect costs of local parasites

Amanda Hund, Joanna K. Hubbard, Tomáš Albrecht, Yoni Vortman, Pavel Munclinger, Simona Krausová, Oldřich Tomášek & Rebecca J. Safran
Many closely related populations are distinguished by variation in sexual signals and this variation is hypothesized to play an important role in reproductive isolation and speciation. Within populations, there is considerable evidence that sexual signals provide information about the incidence and severity of parasite infections, but it remains unclear if variation in parasite communities across space could play a role in initiating or maintaining sexual trait divergence. To test for variation in parasite-associated selection, we...

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....

Type III secretion system effector proteins are mechanically labile

Marc-Andre LeBlanc, Morgan Fink, Thomas Perkins & Marcelo Sousa
Multiple Gram-negative bacteria encode Type III secretion systems (T3SS) that allow them to inject effector proteins directly into host cells to facilitate colonization. To be secreted, effector proteins must be at least partially unfolded to pass through the narrow needle-like channel (diameter < 2 nm) of the T3SS. Fusion of effector proteins to tightly packed proteins—such as GFP, ubiquitin, or dihydrofolate reductase (DHFR)—impairs secretion and results in obstruction of the T3SS. Prior observation that unfolding...

In this overview, the history of and foundational thinking around NEON are discussed....

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...

Stand-level variation drives canopy water storage by non-vascular epiphytes across a temperate-boreal ecotone

Daniel Stanton, Tana Route, Abby Glauser, Kate Hembre & Abigail Meyer
Epiphytes, including bryophytes and lichens, can significantly change the water interception and storage capacities of forest canopies. However, despite some understanding of this role, empirical evaluations of canopy and bole community water storage capacity by epiphytes are still quite limited. Epiphyte communities are shaped by both microclimate and host plant identity, and so the canopy and bole community storage capacity might also be expected to vary across similar spatial scales. We estimated canopy and bole...

Elucidating gene expression adaptation of phylogenetically divergent coral holobionts under heat stress

Viridiana Avila-Magaña, Bishoy Kamel, Michael DeSalvo, Kelly Gómez-Campo, Susana Enríquez, Hiroaki Kitano, Rori Rohlfs, Roberto Iglesias-Prieto & Mónica Medina
As coral reefs struggle to survive under climate change, it is crucial to know whether they have the capacity to withstand changing conditions, particularly increasing seawater temperatures. Thermal tolerance requires the integrative response of the different components of the coral holobiont (coral host, algal photosymbiont, and associated microbiome). Here, using a controlled thermal stress experiment across three divergent Caribbean coral species, we attempt to dissect holobiont member metatranscriptome responses from coral taxa with different sensitivities...
