README This data file is published by the Movebank Data Repository (www.datarepository.movebank.org). As of the time of publication, a version of this published animal tracking dataset can be viewed on Movebank (www.movebank.org) in the study "African elephants in Etosha National Park (data from Tsalyuk et al. 2018)" (Movebank Study ID 605129389). Individual attributes in the data files are defined below and in the Movebank Attribute Dictionary, available at www.movebank.org/node/2381. This dataset was randomly sub-sampled to include 7.4% of the original data set to mask fine-scale movements of this threatened species. Please contact the data owner at wgetz@berkeley.edu for the full dataset. In addition, a different (1-hourly) subsample of 8 of the elephants in this dataset were previously published in Abrahms et al. (2017). This data package includes the following data files: African elephants in Etosha National Park (data from Tsalyuk et al. 2018).csv African elephants in Etosha National Park (data from Tsalyuk et al. 2018)-reference-data.csv These data are described in the following written publication: Tsalyuk M, Kilian W, Reineking B, Marcus W (2018) Temporal variation in resource selection of African elephants follows long term variability in resource availability.

This identifier can be a ring number, a name, the same as the associated tag ID, etc. If the data owner does not provide an Animal ID, an internal Movebank animal identifier may sometimes be shown. example: 91876A, Gary same as: individual-local-identifier animal life stage: The age class or life stage of the animal at the beginning of the deployment. Can be years or months of age or terms such as "adult", "subadult" and "juvenile". Units should be defined in the values (e.g. "2 years"). example: juvenile, adult units: Any units should be defined in the remarks. attachment type: The way a tag is attached to an animal. Values are chosen from a controlled list: collar: The tag is attached by a collar around the animal's neck. glue: The tag is attached to the animal using glue. harness: The tag is attached to the animal using a harness. implant: The tag is placed under the skin of the an animal. tape: The tag is attached to the animal using tape. other: user specified beacon frequency: The frequency of the radio tag or tag retrieval beacon. example: 450.5 units: MHz same as: tag beacon frequency deploy off timestamp: The timestamp when the tag deployment ended. example: 2009-10-01 12:00:00.000 format: yyyy-MM-dd HH:mm:ss.sss units: UTC (Coordinated Universal Time) or GPS time, which is a few leap seconds different from UTC same as: deploy off date deploy on latitude: The geographic latitude of the location where the animal was released (intended primarily for instances in which the animal release and tag retrieval locations have higher accuracy than those derived from sensor data). example: 27.3516 units: decimal degrees, WGS84 reference system deploy on longitude: The geographic longitude of the location where the animal was released (intended primarily for instances in which the animal release and tag retrieval locations have higher accuracy than those derived from sensor data). example: -97.3321 units: decimal degrees, WGS84 reference system deploy on timestamp: The timestamp when the tag deployment started. example: 2008-08-30 18:00:00.000 format: yyyy-MM-dd HH:mm:ss.sss units: UTC (Coordinated Universal Time) or GPS time, which is a few leap seconds different from UTC same as: deploy on date deployment comments: Additional information about the tag deployment that is not described by other reference data terms. example: This deployment was excluded from analysis because the tag failed. deployment ID: A unique identifier for the deployment of a tag on animal, provided by the data owner. If the data owner does not provide a Deployment ID, an internal Movebank deployment identifier may sometimes be shown. example: Jane-Tag42 event ID: An identifier for the set of information associated with each record or event in a data set. A unique event ID is assigned to every time-location or other time-measurement record in Movebank. example: 6340565 units: none latitude (decimal degree): The geographic longitude of a location along an animal track as estimated by the processed sensor data. Positive values are east of the Greenwich Meridian, negative values are west of it. example: -121.1761111 units: decimal degrees, WGS84 reference system same as: location lat longitude (decimal degree): The geographic longitude of a location along an animal track as estimated by the processed sensor data. Positive values are east of the Greenwich Meridian, negative values are west of it. example: -121.1761111 units: decimal degrees, WGS84 reference system same as: location long manipulation type: The way in which the animal was manipulated during the deployment. Additional details about the manipulation can be provided using manipulation comments. Values are chosen from a controlled list: confined: The animal's movement was restricted to within a defined area. none: The animal received no treatment other than the tag attachment. relocated: The animal was released from a site other than the one at which it was captured. manipulated other: The animal was manipulated in some other way, such as a physiological manipulation. sensor type: The type of sensor with which data were collected. Values are chosen from a controlled list: acceleration: The sensor collects acceleration data. accessory measurements: The sensor collects accessory measurements, such as battery voltage. Argos Doppler shift: The sensor is using Argos Doppler shift for determining position. barometer: The sensor records air or water pressure. bird ring: The animal is identified by a ring that has a unique ID. GPS: The sensor uses GPS to find location and stores these. magnetometer: The sensor records the magnetic field. natural mark: The animal is identified by a natural marking. radio transmitter: The sensor is a classical radio transmitter. solar geolocator: The sensor collects light levels, which are used to determine position (for processed locations). solar geolocator raw: The sensor collects light levels, which are used to determine position (for raw light-level measurements). sex: The sex of the biological individual(s) represented in the Occurrence. Values are from a controlled list: m: male f: female study: The name of the study in Movebank in which data are stored. study site: The name of the deployment site, for example a field station or colony. example: Pickerel Island North tag ID: A unique identifier for the tag, provided by the data owner. If the data owner does not provide a tag ID, an internal Movebank tag identifier may sometimes be shown. example: 2342, ptt_4532 same as: tag local identifier tag manufacturer name: The company or person that produced the tag. example: Holohil same as: manufacturer tag model: The model of the tag. example: T61 same as: model tag readout method: The way the data are received from the tag. Values are chosen from a controlled list: satellite: Data are transferred via satellite. phone network: Data are transferred via a phone network, such as GSM or AMPS. other wireless: Data are transferred via another form of wireless data transfer, such as a VHF radio transmitter/receiver. tag retrieval: The tag must be physically retrieved in order to obtain the data. taxon: The scientific name of the species on which the tag was deployed, as defined by the Integrated Taxonomic Information System (ITIS, www.itis.gov). If the species name can not be provided, this should be the lowest level taxonomic rank that can be determined and that is used in the ITIS taxonomy. Additional information can be provided using the term taxon detail. example: Buteo swainsoni same as: species, animal taxon, individual taxon canonical name timestamp: The date and time a sensor measurement was taken. example: 2008-08-14 18:31:00.000 format: yyyy-MM-dd HH:mm:ss.sss units: UTC (Coordinated Universal Time) or GPS time, which is a few leap seconds different from UTC visible: Determines whether an event is visible on the Movebank Search map. Values are calculated automatically, with FALSE indicating that the event has been marked as an outlier by manually marked outlier or algorithm marked outlier. Allowed values are TRUE or FALSE. ----------- More Information For more information about this repository, see www.movebank.org/node/15294, the FAQ at www.movebank.org/node/2220, or contact us at support@movebank.org.
