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 This is a relational database, linking estimates and associated metadata to the relevant study (or unique unpublished combination thereof) by a unique ID number in the 'MASTER' sheet.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 further information, refer to the associated publication, and/or explanatory notes on the column headings of each sheet (.xlsx version only, but provided in the dataset README .txt file). 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 ******************************************************************************************************************************************************* This results in _corrected versions of three items (the originals are retained for clarity): Nicol-Harper_202110_VitalRates_dataset_SUBhs_corrected.csv Nicol-Harper_202110_VitalRates_dataset_MASTER_corrected.csv ...
