Vital rate estimates for the common eider Somateria mollissima, a data-rich exemplar of the seaduck tribe

This database contains estimates of the following vital rates (as required to parameterise matrix population models), for the common eider (Somateria mollissima): 1st year survival (measured either from hatching, or from fledging, to 1 year old); 2nd year survival; adult annual survival; first breeding (both age-specific recruitment probability, and breeding propensity across potential recruitment ages); breeding propensity of established female breeders; clutch size; hatching success; and fledging success. These estimates are drawn from 134 studies, across the scientific and grey literature – including three previously inaccessible datasets on clutch size that were contributed in response to a call for data through the IUCN Species Survival Commission’s Duck Specialist Group (IDs 127, A and B). This is a relational database, linking estimates and associated metadata to the relevant study (or unique unpublished combination thereof) by a unique ID number in the 'MASTER' sheet. For furthe..., We surveyed published academic and grey literature via keyword searches (e.g. “Somateria mollissima” “clutch size”) through Google Scholar, ‘citation snowballing’ (pursuing reference trails; see e.g. Greenhalgh & Peacock, 2005), and cross-referencing authors’ personal databases. Additionally, a call for data was posted on the IUCN Species Survival Commission’s Duck Specialist Group website (www.ducksg.org/2018/10/seaducks/the-not-so-common-eider-can-you-help/), circulated through the corresponding mailing list, and advertised by ANH on Twitter in January 2019 and at conferences (the British Ecological Society’s ‘Quantitative Ecology’ meeting in July 2019; the European Ornithologists’ Union Conference in August 2019; and the Ecological Society of America’s annual meeting in August 2020) thereafter. The call for data elicited three previously inaccessible datasets, of which one was recorded in Icelandic and another in Russian, broadening language coverage since non-English language re..., Please note the following update (also provided in the updated README):
** update 2023/02/20 **
> subspecies 'borealis ' corrected to 'borealis' (i.e. removed space) for ID's 20 and 21 in MASTER and master sheet of full database
> replaced blank cell with 'N/A' for ID 80 in SUBhs and hatch success sheet of full database
> corrected reversed latitude and longitude for ID 62 (which are incorrect in source) in MASTER and master sheet of full database
