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

Margaret L. Eng, Bridget J.M. Stutchbury & Christy A. Morrissey
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...

Lithic Raw Material Characterisation at Olduvai Gorge, Tanzania

Julien Favreau
Olduvai 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. Olduvai’s sedimentary record exhibits a complex sequence of inter-stratified lithic technologies including Oldowan, Acheulean, Middle Stone Age, and Later Stone Age assemblages. While diachronic technological change is perceptible, one aspect that remained largely unchanged through time was the totality of locally available rock types. This study constitutes Olduvai...

Benthic nitrite exchanges in the Seine River (France)

Zahra Akbarzadeh, Anniet Laverman, Fereidoun Rezanezhad, Mélanie Raimonet, Eric Viollier, Babak Shafei & Philippe Van Cappellen
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,...

A multi-scale meteorological dataset of the June 2013 flood in Southern Alberta, Canada

Vincent Vionnet, Vincent Fortin, Etienne Gaborit, Guy Roy, Maria Abrahamowicz, Nicolas Gasset & John Pomeroy
From June 19 to June 22, 2013, intense rainfall and concurrent snowmelt led to devastating floods in the Canadian Rockies, foothills and downstream areas of southern Alberta (Canada). The complexity of the topography in the upper catchments and the presence of snow at high elevations made, among other factors, hydrological forecasting challenging for this extreme event. This dataset contains an ensemble of variables at different resolutions (10, 2.5 and 1 km) that can be used...

An ensemble of 500 time series of weekly flows from 1600-2001 for the four sub-basins of the Saskatchewan River Basin generated through disaggregating tree-ring reconstructed flow.

Andrew Slaughter & Saman Razavi
Biennial flow reconstructions generated through multiple linear regression relationships between flow and tree-ring chronologies extending from 1600–2001 were disaggregated to weekly by identifying two-year periods in the naturalised reference flow broadly similar to that of the reconstructed flow. The weekly flow distribution of the identified naturalised reference flow period was used to construct the weekly flow. Scaling methods were used to re-introduce some of the variability in yearly flows lost during the disaggregation process. The...

Bedload sediment transport and morphologic data in semi-alluvial rivers conditioned by urbanization and stormwater management

Elli Papangelakis, Bruce MacVicar & Peter Ashmore
Watershed urbanization and stormwater management (SWM) alter the hydrologic and geomorphologic processes of rivers. This purpose of this study is to characterize the bedload sediment transport regime of semi-alluvial gravel-bed rivers, and how it is affected by watershed urbanization and common SWM strategies. Data was collected from three rivers in the Greater Toronto Area of Southern Ontario: Ganatsekaigon Creek (City of Pickering), Wilket Creek (City of Toronto), and Morningside Creek (City of Toronto). The grain...
