These tables serve as input data for hierarchical models investigating interactions between raven density and Greater Sage-grouse nest success. Observations were recorded over an 11 year time period, spanning from 2009 through 2019. The model is run in JAGS via R, the code is publicly available via the U.S. Geological Survey's GitLab (O'Neil et al. 2023). We recommend not making any changes or edits to the tables unless the user is experienced with hierarchical modeling.

This collection of files contains temperature data files (.ttd files) downloaded directly from Tiny Tag devices, as well exported temperature data as .csv files for each nest monitored with Tiny Tags by year. File names include Tiny Tag number, site, year, and nest ID..ttd files can be viewed using Tinytag Explorer. Note, however, that the times displayed by Tinytag Explorer are calculated when the data is displayed and depend on the daylight saving settings of the PC at that time. For example, if a .ttd file is opened before and after DST settings change, then all times displayed by Tinytag Explorer will go forward or back. All .csv files were exported using the Tinytag Explorer during the same daylight savings...

This file contains information pertaining to the survey plot including date and time of surveyed, survey conditions, plot location, and ecological and biological conditions of the survey plot. The data providers have invested considerable effort in QA/QC, but it is possible that undetected errors remain. It is strongly recommended that careful attention be paid to the contents of the metadata file associated with these data to evaluate data set limitations, restrictions or intended use. The originators of this dataset shall not be held liable for improper or incorrect use of the data described and/or contained herein.

Data on intraguild predation of arthropods on the tarweed Hemizonia congesta. Arthropod counts (predators, herbivores, etc) and counts of entrapped arthropod corpses on focal plants in an experiment manipulating arthropod carrion amount and plant damage. Quantifications of plant damage and reproduction are presented. A duplicate digital object identifier (DOI) (https://doi.org/10.5066/F7M044NW) was accidentally published for this resource. The correct DOI for referencing this product is https://doi.org/10.5066/P9PD6HUW.​​​​​​​

The primary objective of this project was to monitor the growth of shorebird chicks by recapturing them from hatch to fledgling in relation to food abundance and weather conditions. In 2014 and 2015, we attempted to estimate the impacts of trophic mismatch by experimentally creating late hatched broods by refrigerating eggs to delay hatch. Transmitters were then attached to adults and chicks to follow and recapture chick in order to estimate growth rates and survival (see annual protocol documents for further information).Information for the Utqiagvik chick monitoring study were obtained concurrently with information obtained for the Utqiagvik shorebird project and information on chicks and nests included in these...

This file contains information on avian nests found during this study including species, date and time found, location, status, estimated incubation dates, tiny tag and camera monitoring and retrieval information, and nest fate. Note, that .ttd files viewed using Tinytag Explorer may have assessment times that are off by an hour, as the times displayed by Tinytag Explorer are calculated when the data is displayed and depend on the daylight saving settings of the PC at that time. For example, if a .ttd file is opened before and after DST settings change, then all times displayed by Tinytag Explorer will go forward or back. Also, in 2019 camera date and times were not set correctly prior to deployment. See fields...

This file contains information on incidental observations of lemmings and potential shorebird predators from 2018 and after by year including date and time, location, and predator or lemming observations. Data were separated by time period due to changes in methodologies that occurred in 2018.The data providers have invested considerable effort in QA/QC, but it is possible that undetected errors remain. It is strongly recommended that careful attention be paid to the contents of the metadata file associated with these data to evaluate data set limitations, restrictions, or intended use.

Collection of photographs taken during Utqiagvik chick monitoring field work. Photos include those taken of completed chick monitoring datasheets by year.Information for the Utqiagvik chick monitoring study were obtained concurrently with information obtained for the Utqiagvik shorebird project and information on chicks and nests included in these files is also contained within the Utqiagvik shorebird project archive (file://ifw7ro-file.fws.doi.net/datamgt/mbm/mbmsh_009_Utqiagvik_shorebird_project). If there are discrepancies between the files please use the information contained within the Utqiagvik shorebird project files. Additional information on chick growth was also obtained in 2013 by Kirsten Grond and is...

Rasters representing median raven density estimates, calculated from approximately 28,000 raven point count surveys conducted between 2009 and 2019. Estimates were the result of a Bayesian hierarchical distance sampling model, using environmental covariates on detection and abundance.

This file includes R code to select annual sampling units for nest survival analysis on the Arctic National Wildlife Refuge using a stratified random sampling approach. We used the Generalized Random Tessellation Stratified (GRTS) procedure (Stevens and Olsen 2004) to obtain a spatially balanced sample of 28 plots in 2019 and 48 in 2022 within two of the four strata. In 2019, plots were equally allocated between wetland and moist strata, with 14 plots allocated to each. In 2022, additional plots were allocated to the moist stratum given the proportional availability on the landscape, with the final allocation being 30 moist plots and 18 wetland plots. We also selected an additional 20 “oversample” plots in each...

In 2008 and 2009, we investigated the survival of chicks from initial and experimentally-induced replacement nests of arcticola Dunlin (Calidris alpina) breeding near Utqiaġvik, Alaska. We monitored survival of 66 broods from 41 initial and 25 replacement nests. See Saalfeld, S.T., B.L. Hill, C.M. Hunter, C.J. Frost, and R.B. Lanctot. 2021. Warming Arctic summers unlikely to increase productivity of shorebirds through renesting.

Cisco (Coregonus artedi) have been extirpated from Lake Erie since the 1960s, but they once supported one of the largest Laurentian Great Lakes fisheries. Reintroduction may be beneficial to the Lake Erie fishery, but impediments for re-establishment are not fully understood. This data set aimed to use acoustic telemetry to investigate the thermal habitat use and survival of hatchery-reared adult Cisco in Lake Erie. Fish were experimentally released (n=50 per site) at two locations: near Dunkirk, New York, and Huron, Ohio. Fish were tracked using the Great Lakes Acoustic Telemetry Observation System (GLATOS).

Collection of video files taken of avian nests by Plotwatcher Pro–Time Lapse cameras during field work conducted on the Arctic National Wildlife Refuge. Photos are organized in folders by year. Naming convention for each photo includes nest ID and camera number. Within each NestID folder are a series of TLV files saved directly from cameras. TLV files can be saved as an AVI file to view in Windows. Note, in 2019 camera date and times were not set correctly prior to deployment. See ‘ANWR nest survival nest data’ for date and time as set on the camera at time of deployment. The data providers have invested considerable effort in QA/QC, but it is possible that undetected errors remain. It is strongly recommended that...
