Space survey and behavioural questionnaire
A space survey following the format of EAZA supplemented by a questionnaire on husbandry data was developed in collaboration with the studbook keeper and species coordinator, Ewa Wikberg, Nordens Ark, Sweden, and distributed to all 33 holding institutions in March 2014.
A studbook analysis was done by using the European Studbook (ESB) for the species in Poplink. All sires that had succeeded to reproduce from 1973-2013 were chosen, and the facts about their inbreeding coefficient, litter size etc., were compiled in an Excel-document to investigate the possible correlation between litter size and inbreeding coefficient.
Four pairs (4.4) at 4 different holding institutions within the ESB were chosen for behavioural observations of exhibit use, activity budget and stereotypic behaviour. The exhibits were two open air, >500m 2 exhibits and two roofed, <50m 2 exhibits.
