Declarations
:
: No European bison were killed specifically for this study. Blood samples were collected from animals culled by the authorities responsible for managing European bison in Białowieża National Park in BF, and the Knyszyn Forest District in KF with permission issued each year by the General Directorate for Environmental Protection. The animals were culled for various reasons, including being victims of road accidents, causing conflicts, being injured or sick, or for population control purposes. The culling of and sampling from European bison, a protected species, is regulated by the Polish Nature Conservation Act adopted on 16 April 2004 (Journal of Laws no 92/2004, item 880).
