Data Records

The data in this 出現紀錄 resource has been published as a Darwin Core Archive (DwC-A), which is a standardized format for sharing biodiversity data as a set of one or more data tables. The core data table contains 5,253 records.

This IPT archives the data and thus serves as the data repository. The data and resource metadata are available for download in the downloads section. The versions table lists other versions of the resource that have been made publicly available and allows tracking changes made to the resource over time.

取樣方法

Since 1981, the Icelandic Institute of Natural History has surveyed rock ptarmigan using a distance sampling methodology (Buckland et al., 2001) along road transects located in the lowlands to derive population indices (Icelandic Institute of Natural History, 2021a). Transects are monitored in late April or early May, which corresponds to the period when birds are expected to have moved to the breeding grounds, where they will stay until the end of August (Gardarsson, 1988). During sampling, observers recorded the location on the transect when a bird was observed as well as the distance from the transect to the bird and whether it was located on the left or the right side of the transect (Ferrarini, 2022). In 2011, data from 2005 to 2010 were processed and assigned a geographic position for each bird sighting, i.e., using the distance to the individual and direction of the observation, geographic records were moved from the transect to the estimated location of the animal.
