Single year data tables by facility – releases, transfers and disposals

Paulo Costa &
The National Pollutant Release Inventory (NPRI) is Canada's public inventory of pollutant releases (to air, water and land), disposals and transfers for recycling. This file contains the most commonly used NPRI data fields, within a simplified tabular format, including all facility-reported pollutant releases, disposals and transfers for recycling for a given year, listed by facility and substance. There are important factors that should be considered prior to the use and interpretation of NPRI data. Additional...

Taylor, Helen Trefry, Carol M. Vleck, David Vleck … & D. Ryan Norris
Latitudinal differences in timing of breeding are well documented but how such differences carry over to influence timing of events in the annual cycle of migratory birds is not well understood. We examined geographic variation in timing of events throughout the year using light-level geolocator tracking data from 133 migratory tree swallows (Tachycineta bicolor) originating from 12 North American breeding populations. A swallow’s breeding latitude influenced timing of breeding, which then carried over to affect...

Data from: Limited consequences of infestation with a blood-feeding ectoparasite for the nestlings of two North Pacific seabirds

J. Mark Hipfner, Douglas F. Bertram & Mark C. Drever
The seabird tick (Ixodes uriae) parasitizes over 60 host species in the circumpolar regions of both hemispheres, and acts as a vector for a number of potentially virulent pathogens. On Triangle Island, British Columbia, Canada, the nestlings of Cassin’s Auklet (Ptychoramphus aleuticus) and Rhinoceros Auklet (Cerorhinca monocerata) are often parasitized by seabird ticks, which may affect their growth and survival in the nest. We used a logistic growth model to interpolate between successive measures of...

Maps of reporting facilities – virtual globe format

Paulo Costa &
The National Pollutant Release Inventory (NPRI) is Canada's public inventory of pollutant releases (to air, water and land), disposals and transfers for recycling. Each file contains the NPRI map layers in a KMZ format that you can use with virtual globe software such as Google Earth™. Data are available for the last two reporting years. You can filter the data by province or industry type. Select a facility to view a report that summarizes its...

Data from: Seabird species vary in behavioural response to drone census

Émile Brisson-Curadeau, David Bird, Chantelle Burke, David A. Fifield, Paul Pace, Richard B. Sherley & Kyle H. Elliott
Unmanned aerial vehicles (UAVs) provide an opportunity to rapidly census wildlife in remote areas while removing some of the hazards. However, wildlife may respond negatively to the UAVs, thereby skewing counts. We surveyed four species of Arctic cliff-nesting seabirds (glaucous gull Larus hyperboreus, Iceland gull Larus glaucoides, common murre Uria aalge and thick-billed murre Uria lomvia) using a UAV and compared censusing techniques to ground photography. An average of 8.5% of murres flew off in...

Five-year data tables by province, industry and substance – releases

Paulo Costa &
The National Pollutant Release Inventory (NPRI) is Canada's public inventory of pollutant releases (to air, water and land), disposals and transfers for recycling. These files contain NPRI release data for the past five years in CSV format, aggregated by Province, Industry Type and Substance, and disaggregated by media (air, water and land). The number of reporting facilities represented by each aggregated data point is included*. The results can be further broken down using the pre-defined...

Data from: Tracking data and retrospective analyses of diet reveal the consequences of loss of marine subsidies for an obligate scavenger, the Andean condor

Sergio A. Lambertucci, Joan Navarro, Jose Antonio Sánchez-Zapata, Keith A. Hobson, Pablo A.E. Alarcón, Guillermo Wiemeyer, Guillermo Blanco, Fernando Hiraldo & Jose Antonio Donazar
Over the last century, marine mammals have been dramatically reduced in the world’s oceans. We examined evidence that this change caused dietary and foraging pattern shifts of the Andean condor (Vultur gryphus) in Patagonia. We hypothesized that, after the decrease in marine mammals and the increase in human use of coastlines, condor diet changed to a more terrestrial diet which, in turn, influenced their foraging patterns. We evaluated the diet by means of stable isotope...
