title: Petrographic Characterization of Raw Material Sources at Oldupai Gorge, Tanzania

description: Oldupai Gorge is located within the Ngorongoro Conservation Area, a UNESCO World Heritage Site in northern Tanzania along the western margin of the East African Rift System. Oldupai’s sedimentary record exhibits a complex sequence of inter-stratified lithic assemblages associated with the Early, Middle, and Later Stone Age. While diachronic technological change is perceptible, the totality of locally available rocks remained largely unchanged through time. Here, thin section petrography, Scanning Electron Microscopy-Energy Dispersive X-Ray Spectroscopy, and Electron Probe Micro Analysis were employed to characterize source lithologies in the Oldupai region. One of our goals was to determine if outcrops have rock types with unique mineral compositions amenable for sourcing lithic artifacts. Geological samples were collected in primary and secondary positions, from which sixty-two samples were selected for analysis. Comparative analyses show that five outcrops have quartzites with unique mineral compositions, seven meta-granite varieties are unique to five individual outcrops, Engelosin phonolite samples are texturally and mineralogically unique, and magmatic samples recovered in secondary position may be sourced to their volcanic center. Our results demonstrate it is feasible to differentiate between source materials using optical mineralogy which implies that sourcing lithic artifacts based on mineral compositions is possible. This is further substantiated by assigning the source/s for previously described fuchsitic quartzite artifacts from three archaeological sites at Oldupai as this raw material type uniquely occurs at two nearby outcrops. Systematic archaeological testing will allow future researchers to glean new understandings of hominin behavior and resource procurement within the Oldupai paleobasin.

title: Data file for: A neonicotinoid insecticide reduces fueling and delays migration in songbirds

description: Abstract: Neonicotinoids are neurotoxic insecticides widely used as seed treatments, but little is known of their effects on migrating birds that forage in agricultural areas. We tracked the migratory movements of imidacloprid-exposed songbirds at a landscape scale using a combination of experimental dosing and automated radio telemetry. Ingestion of field-realistic quantities of imidacloprid (1.2 or 3.9 milligrams per kilogram body mass) by white-crowned sparrows (Zonotrichia leucophrys) during migratory stopover caused a rapid reduction in food consumption, mass, and fat and significantly affected probability of departure. Birds in the high dose group stayed a median of 3.5 days longer at the site of capture after exposure as compared with controls, likely to regain fuel stores or recover from intoxication. Migration delays can carry over to affect survival and reproduction; thus, these results confirm a link between sublethal pesticide exposure and adverse outcomes for migratory bird populations.

title: Initial Assessment of Bioavailable Strontium at Oldupai Gorge, Tanzania: Potential for Early Mobility Studies

description: Strontium isotope analysis is a useful tool for tracing mobility and migration in past populations. For it to be employed, the 87Sr/86Sr values of the landscape must be well-understood. Bioavailable strontium is a combination of geological and atmospheric strontium available for use by plants and animals. In this study we begin mapping bioavailable strontium values around the Oldupai Gorge region so that this method may be utilized on archaeological hominins and animals in the future. We analyzed three plants from 33 localities across volcanic and metamorphic bedrock, including the regional drainage sump, Olbalbal. We found that bioavailable strontium in the region is homogeneous overall, with trends towards increasing values to the north and northeast and in Olbalbal. There was no difference between 87Sr/86Sr values of metamorphic and volcanic areas. Migrants from outside the study area with different isotopic values will be easily identifiable from the local residents. As a proof of concept, we analyzed 7 animal teeth (hippopotamus, crocodile, and equid) from Engaji Nanyori, a Bed III and IV site at Oldupai Gorge. We found that enamel and dentine which had been acetic acid treated to remove diagenetic strontium were significantly different from one another. All animals had higher 87Sr/86Sr values than the plant values, suggesting that modern and ancient bioavailable strontium values may have been different, likely due to environmental differences.

title: Hydrometeorological, glaciological and geospatial research data from the Peyto Glacier Research Basin in the Canadian Rockies

description: Hydrological, meteorological, glaciological, and geospatial data of the Peyto Glacier Research Basin (PGRB) in the Canadian Rockies are presented. Peyto Glacier has been of great interest to glaciological and hydrological research since the 1960s for the study of mass and water balance during the International Hydrological Decade (IHD, 1965-1974). Intensive studies of the glacier and observations of the glacier mass balance continued after the IHD, when the initial seasonal meteorological stations were discontinued, then restarted as continuous stations in the late 1980s. The corresponding hydrometric observations were discontinued in 1977 and restarted in 2013. Data sets presented here include: high resolution, co-registered DEMs derived from original air photos and LiDAR surveys; hourly off-glacier meteorological data recorded from 1987 to present; precipitation data from Bow Summit; and long-term hydrological and glaciological model forcing datasets derived from bias-corrected reanalysis products.

title: A soil moisture and precipitation dataset from the Kenaston/Brightwater Creek basin, Saskatchewan, Canada, 2007 - 2017

description: The Kenaston Network, located in the Brightwater Creek basin in central Saskatchewan, is a community monitoring network with a variety of monitoring instruments. The area is a typical agricultural region with both annually cropped fields and pasture sections. Dataset presented here is from the soil moisture and precipitation sites which are spread at two spatial scales (10 km x 10 km and 40 km x 40 km) over the monitoring region. Data from the summer months (May 1 – Sept 30) is included for 2007 – 2017. Each site has at least three Stevens Hydra Probe soil moisture sensors, inserted horizontally at depths of 5, 20, and 50 cm below the surface, with sites at the 10 km x 10 km scale instrumented with an additional vertically placed sensor, measuring over the depth 0-5 cm. Parameters reported from the probes are soil temperature, real dielectric constant, and soil moisture calculated using the Stevens loam calibration equation. All sites have one of two types of tipping bucket rain gauge (Onset RG3 or Hydrological Services TB3) to provide summer precipitation totals. All data from the network have been through a quality control/quality analysis process that includes a series of automated checks followed by a manual review of all sensor parameters. **Please note: This dataset is linked to an ESSD paper at https://doi.org/10.5194/essd-11-787-2019.  The authors kindly request that you reference this paper in addition to the dataset.

title: Stem radius change from Picea mariana and Larix laricina at the Old Black Spruce site, Boreal Research Ecosystem and Monitoring Sites (BERMS)

description: This dataset holds stem radius data collected at the Boreal Ecosystem Research and Monitoring Sites (BERMS). Stem radius change was monitored at the Old Black Spruce site (OBS) (53. 98 ºN, 105.12 °W) from the two dominant tree species, black spruce (Picea mariana) and eastern larch (Larix laricina). The stem radius change was measured with the use of circumference band dendrometers, type DC2 and DC3 from Ecomatik (Ecomatik, Germany), and recorded every 30 min using a HOBO UX120-006M data logger. An array composed of four or less dendrometers were affixed to individual trees of the same species and connect to the same data logger. There was a total of eight arrays at OBS, four monitoring 13 P. mariana trees, and four monitoring 13 L. laricina trees. There are periods where data from less dendrometers are available due to logger failure and/or wild animals interfering on measurements. No gap filling technique was used when gaps were present. This dataset includes data that have been processed for analysis. More details on the measurements and data processing can be found in the README file.

title: List of global birds with ED scores and zoo holding data

description: We calculated "evolutionary distinctness" (ED) scores using an updated distribution of phylogenies incorporating a total of 10, 284 extant bird species as recognized by the IUCN, based on the distribution of "Hackett backbone" trees used by Jetz et al. [2014]. The ED metric was first presented by Redding [2003], (also known as the "Fair Proportion" measure), and sums the lengths of the branches on the path from a species to the root, with each branch length inversely weighted by the number of living species that ultimately descend from it. Next we compiled a list of all species indicated as being held in captivity by the Zoological Information Management System (ZIMS): the largest database regarding ex-situ holdings from 960 institutions worldwide [Species 360, 2016]. A species was scored as being in a zoo if there was a record of at least one individual being held ex-situ in the ZIMS database up to March 2016. Software used was R. This dataset was originally deposited in the Simon Fraser University institutional repository.

title: Infants' looking to surprising events: When eye-tracking reveals more than looking time

description: Research on infants' reasoning abilities often rely on looking times, which are longer to surprising and unexpected visual scenes compared to unsurprising and expected ones. Few researchers have examined more precise visual scanning patterns in these scenes, and so, here, we recorded 8- to 11-month-olds' gaze with an eye tracker as we presented a sampling event whose outcome was either surprising, neutral, or unsurprising: A red (or yellow) ball was drawn from one of three visible containers populated 0%, 50%, or 100% with identically colored balls. When measuring looking time to the whole scene, infants were insensitive to the likelihood of the sampling event, replicating failures in similar paradigms. Nevertheless, a new analysis of visual scanning showed that infants did spend more time fixating specific areas-of-interest as a function of the event likelihood. The drawn ball and its associated container attracted more looking than the other containers in the 0% condition, but this pattern was weaker in the 50% condition, and even less strong in the 100% condition. Results suggest that measuring where infants look may be more sensitive than simply how much looking there is to the whole scene. The advantages of eye tracking measures over traditional looking measures are discussed. The Excel file here includes information about cumulative eye-tracker coded looking to the various AOIs (areas of interest). Additional information about the spreadsheet's column headers can be found in the accompanying ReadMe (ReadMe.txt). Confidentiality declaration: Consent procedures were approved by the UCLA North General Institutional Review Board, which included written consent from all infants' parents prior to study participation. Confidentiality of the participants is maintained here, because anonymous subject numbers are used to label the data, which cannot be linked to any confidential subject information.

title: Benthic nitrite exchanges in the Seine River (France)

description: We expanded the reaction network for benthic N cycling in an existing early diagenetic computer code in order to explicitly include the reaction pathways producing and consuming nitrite. Reactive transport calculations are then used to interpret a data set comprising pore water profiles and benthic exchange fluxes of nitrate, nitrite and ammonium collected in the Seine River upstream and downstream of the SAV WWTP. Because of the highly dynamic and heterogeneous nature of streambed sediments, we primarily aim to capture the general trends of the measured pore water depth profiles and benthic fluxes. We then use the model as a sensitivity tool to delineate the main controls on benthic exchange fluxes of nitrite.

title: Data for: Comparative valuation of potential and realized ecosystem services in Southern Ontario, Canada

description: Because realized ecosystem services are directly consumed by people and clearly illustrate the link between ecosystem services and human well-being, the aim of this project was to distinguish potential and realized ecosystem services in Southern Ontario's landscape. The initial dataset used for this project was the Southern Ontario Land Resource Information System (SOLRIS) land use updated to 2016 for ecoregions 6E and 7E. Our analysis of these data yields a total potential value of the bundled ecosystem services of $19 billion per year for Southern Ontario. To estimate the value of the realized (or used) ecosystem services, the potential values are scaled by the corresponding relative use indices. The resulting value of the realized ecosystem services is $9.7 billion per year, that is, about 50% of the value of the potential ecosystem services.

title: Oxidation of Fe(II) by Flavins under Anoxic Conditions

description: This project aims to understand the redox reaction between Fe(II) and flavins. Our study demonstrated that aqueous Fe(II) can be oxidized by the oxidized form of riboflavin and flavin mononucleotide at pH 7–9. Both the rates and extents of oxidation increased with increasing concentration of oxidized flavins and increasing solution pH. Our data are from experiments, which mainly consist of the chemical variables, were collected in the Ecohydrology lab at the University of Waterloo using the batch reaction system. All the experiments were conducted in 125 mL serum bottles at 22±1 ℃ in an anaerobic glovebox (95% N2 and 5% H2). The bottles contained Teflon-coated magnetic stir bars and were wrapped in aluminum foil to exclude light. Prior to an experiment, a solution containing 20 mM buffer and 10 mM NaCl was purged with N2 (99.998%) for at least 2 h to remove O2, then transferred to the anaerobic glovebox. Aqueous Fe2+ and uncomplexed RBF and FMN concentrations were analyzed by using a Flexstation Multimode Microplate Reader. The total concentrations of RBF and FMN were determined at 450 nm on a UV-vis spectrometer kept in the anaerobic glovebox Additional details on the project are available in Environmental Science and Technology publication titled "Oxidation of Fe(II) by flavins under anoxic conditions" (doi: 10.1021/acs.est.0c02916)

title: Instantaneous Iodine-Assisted DNAzyme Cleavage of Phosphorothioate RNA

description: We show that Ce13d DNAzymes can use non-electrostatic interactions to assist RNA cleavage by making simple Phosphorothioate (PS) modifications at the cleavage junction. In this case, Iodine can replace the role of a metal cofactor, acting directly on the scissile phosphate group. This finding has broadened the scope of DNAzyme catalysis. This DNAzyme was further engineered for fluorescence-based I2 detection with a detection limit of 4.7 nM. In addition, Oxidation of I− with Fe3+ produced I2 in situ, allowing detection of Fe3+ down to 78 nM.
