Biega, Alannah M.; Mooers, Arne O.; Lamont, Myles; Bowkett, Andrew E.; Martin, Thomas E. 2018-01-17 We calculated "evolutionary distinctness" (ED) scores using an updated distribution of phylogenies incorporating a total of 10, 284 extant bird species as recognized by the IUCN, based on the distribution of "Hackett backbone" trees used by Jetz et al. [2014]. The ED metric was first presented by Redding [2003], (also known as the "Fair Proportion" measure), and sums the lengths of the branches on the path from a species to the root, with each branch length inversely weighted by the number of living species that ultimately descend from it. Next we compiled a list of all species indicated as being held in captivity by the Zoological Information Management System (ZIMS): the largest database regarding ex-situ holdings from 960 institutions worldwide [Species 360, 2016]. A species was scored as being in a zoo if there was a record of at least one individual being held ex-situ in the ZIMS database up to March 2016. Software used was R. This dataset was originally deposited in the Simon Fraser University institutional repository.

Map search instructions

1.Turn on the map filter by clicking the “Limit by map area” toggle.
2.Move the map to display your area of interest. Holding the shift key and clicking to draw a box allows for zooming in on a specific area. Search results change as the map moves.
3.Access a record by clicking on an item in the search results or by clicking on a location pin and the linked record title.
Note: Clusters are intended to provide a visual preview of data location. Because there is a maximum of 50 records displayed on the map, they may not be a completely accurate reflection of the total number of search results.
