Keshav Bharadwaj, O. Burkan Isgor & W. Jason Weiss
This dataset contains the chemical composition and reactivities of commercially used SCMs such as silica fume, Class-F and Class-C fly ashes, slags, and calcined clays. The dataset also includes the chemical composition and reactivity (where available) for several SCMs that are currently not specified in standard specifications by ASTM or AASHTO such as fly ashes not conforming to ASTM C618, bottom ashes, and pumices. This dataset can be used (i) for the classification of SCMs...

Transitioning from environmental genetics to genomics using mitogenome reference databases

Emily Dziedzic
Species detection using eDNA is revolutionizing the global capacity to monitor biodiversity. However, the lack of regional, vouchered, genomic sequence information—especially sequence information that includes intraspecific variation—creates a bottleneck for management agencies wanting to harness the complete power of eDNA to monitor taxa and implement eDNA analyses. eDNA studies depend upon regional databases of complete mitogenomic sequence information to evaluate the effectiveness of such data to differentiate, identify and detect taxa. We created the Oregon...

Ventenata Dubia Cover, forb diversity and forb richness

Scott Lukas, Brogan Watson, Lesley Morris, Sandra DeBano, Joshua Leffler & Heidi Schmalz
Questions: Grassland degradation due to agriculture, changing fire regimes, and invasive species negatively affects forb communities. Conserving forbs and the services they provide requires a better understanding of their responses to interacting disturbances. Although fire and livestock grazing are important disturbances, their effect on forb communities in the Pacific Northwest Bunchgrass Prairies is not fully understood. Our objectives were to: 1) determine how prescribed fire and livestock grazing influence forb community composition, cover, species richness,...

Combining metabolomics and experimental evolution reveals key mechanisms underlying longevity differences in laboratory evolved Drosophila melanogaster populations

Mark Phillips, Kenneth R. Arnold, Zer Vue, Heather K. Beasley, Edgar Garza-Lopez, Andrea G. Marshall, Derrick J. Morton, Melanie R. McReynolds, Thomas T. Barter & Antentor Hinton
Experimental evolution with Drosophila melanogaster has been used extensively for decades to study aging and longevity. In recent years, the addition of DNA and RNA sequencing to this framework has allowed researchers to leverage the statistical power inherent to experimental evolution to study the genetic basis of longevity itself. Here, we incorporated metabolomic data into to this framework to generate even deeper insights into the physiological and genetic mechanisms underlying longevity differences in three groups...

Data from: Comparing the efficacy of control strategies for infectious disease outbreaks using field and simulation studies

Bhim Chaulagain, Jean Bertrand Contina, Karasi Mills, Rachel L. Seibel & Christopher C. Mundt
Diseases characterized by long distance inoculum dispersal (LDD) are among the fastest spreading epidemics in both natural and managed landscapes. Management of such epidemics is extremely challenging because of asymptomatic infection extending at large spatial scales and frequent escape from the newly established disease sources. We compared the efficacy of area- and timing-based disease management strategies in artificially initiated field epidemics of wheat stripe rust and complemented with simulations from an updated version of the...

Population changes in a whale breeding ground revealed by citizen science noninvasive genetics unique microsatellite profiles of southern right whales

Petra Neveceralova, Emma Carroll, Debbie Steel, Els Vermeulen, Simon Elwen & Pavel Hulva
Historical exploitation, and a combination of current anthropogenic impacts, such as climate change and habitat degradation, impact the population dynamics of marine mammalian megafauna. Right whales (Eubalaena spp.) are large cetaceans recovering from hunting, whose reproductive and population growth rate appear to be impacted by climate change. We apply noninvasive genetic methods to monitor southern right whale (E. australis, SRW) and test the application of noninvasive genetics to minimise the observer effects on the population....

Factors influencing transferability in species distribution models

Josée Rousseau & Matthew Betts
Species distribution models (SDMs) provide insights into species’ ecology and distributions and are frequently used to guide conservation priorities. However, many uses of SDMs require model transferability, which refers to the degree to which a model built in one place or time can successfully predict distributions in a different place or time. If a species’ model has high spatial transferability, the relationship between abundance and predictor variables should be consistent across a geographical distribution. We...

Strong migratory connectivity indicates Willets need subspecies-specific conservation strategies

Allison Huysman, Nathan Cooper, Joseph Smith, Susan Haig, Susan Heath, Luanne Johnson, Elizabeth Olson, Kevin Regan, Jennifer Wilson & Peter Marra
By combining all available banding and tracking data, we found that Willets (Tringa semipalmata) have strong migratory connectivity between breeding and nonbreeding locations at the range-wide and subspecies levels, exposing the two subspecies to varying threats such as hunting for the eastern subspecies (T. s. semipalmata) and climatically-altered coastal habitats for both subspecies. We found that Western Willets (T. s. inornata) primarily used nonbreeding habitats along the Pacific Coast of the United States, although their...

Sizes of steelhead families raised in hatchery tanks vs in artificial streams

Michael Blouin
Salmonid fish raised in hatcheries often have lower fitness (number of returning adult offspring) than wild fish when both spawn in the wild. Body size at release from hatcheries is positively correlated with survival at sea. So one explanation for reduced fitness is that hatcheries inadvertently select for trait values that enhance growth rate under the unnatural environment of a hatchery, but that are maladaptive in the wild environment. A simple prediction of this hypothesis...

Avian botulism is a primary, year-round threat to adult survival in the endangered Hawaiian Duck (Anas wyvilliana) on Kaua‘i, Hawai‘i, USA

Christopher Malachowski, Bruce Dugger, Kimberly Uyehara & Michelle Reynolds
Adult survival is the most important demographic parameter influencing population dynamics for many bird taxa. Thus, understanding how survival probabilities and causes of mortality vary throughout the annual cycle is critical for developing informed and effective management strategies. In this study, we used radio-telemetry data to evaluate the effects of biotic (e.g., sex, peak [September–April] vs. off-peak [May–August] nesting seasons) and abiotic factors (e.g., rainfall, year, bi-monthly interval) on adult survival, estimate annual survival probabilities,...

Increasing Instability of a Rocky Intertidal Meta-Ecosystem

Bruce Menge
Climate change threatens to destabilize ecological communities, potentially moving them from persistently-occupied “basins of attraction” to different states. Increasing variation in key ecological processes can signal impending state shifts in ecosystems. In a rocky intertidal meta-ecosystem consisting of three distinct regions spread across 260 km of the Oregon coast, we show that annually cleared sites are characterized by communities that exhibit signs of increasing destabilization (loss of resilience) over the past decade despite persistent community...

Survey of winter bird communities and vegetation in the Oregon Coast Range

Nolan Clements & W Douglas Robinson
We re-surveyed forest bird communities during winter in seven large plots originally surveyed by graduate student, Stanley Anderson, from 1968 through 1970, near Corvallis, Oregon, USA. The forests in plots in the Coast Range Mountain foothills were and are currently dominated by Douglas-fir (Pseudotsuga menziesii). Anderson's thesis included plot locations, summaries of vegetation characteristics and point estimates of bird densities for each plot. Because of the lack of similar data, we re-surveyed his plots after...

Data from: Boosts in photosynthetic capacity linked with post-fire tree survival

Kelsey Bryant, Hyojung Kwon, Crystal Kolden, Jeffrey Stenzel, Justin Mathias, Laurel Lynch & Tara Hudiburg
Forests mitigate climate change by storing massive amounts of carbon. Increases in wildfire activity threaten forest carbon storage, but mechanisms controlling tree carbon uptake and survival remain unresolved. Our current understanding is largely informed by laboratory and low-intensity fire experiments, none of which have focused on mature trees. We are the first to quantify carbon uptake by a wide-spread tree species immediately following wildfire that caused variable degrees of damage. Burned trees indicated less water...
