    Beavers are known as biggest rodents leaving in Europe and North America. Two species are included in beaver family: eurpoean beaver (Castor fiber, L.1758) and candian beaver (Castor canadensis, Kuhl 1820). In ancient times beavers existed in whole Europe and in the part of Asia, while their population in Europe decreased systematically from IX century on due to extensive hunts. Consequently, in the end of XIX century only few beavers groups existed in Europe. Within after second world war Poland numerically 130 specimens of European beaver were present. Since then on active protection of this species has started including many environmental programs. It resulted in systematic increase of beaver specimens. Currently beavers came back to their previous regions and some new regions are occupied as well. Their amount reaches over 89000 specimens. This manuscript presents detailed structure of beavers body and their physiology allowing to leave In both water and on land. Beavers natural feed, digestive track, digestive process are described as well. Issues related to reproduction and bringing up are described too. Natural predators are presented. Inside and outside parasites with their action are presented.

    Morphometric study of the uterus of lowland European Bison Bison Bonasus (Linnaeus, 1758)

    Despite successful restitution in Poland, European bison still belongs to endangered species. The aim of study was to describe the morphology of the uterus of European bison and to perform morphometric analysis of the organ as well as to compare findings with available data on domestic cattle. The material consisted of female genital organs obtained from 55 females living in the Białowieża Forest. The animals were divided into two age groups. Group I consisted of 36 sexually immature females, while group II comprised 19 sexually mature animals. Significant differences were observed between the two age groups. In young female uteri, except cranial parts of horns, lay in the pelvic cavity. In older animals, most of which have already given birth, uteri were bigger, therefore only a distal half of the cervix was located in the pelvis, while the rest of the organ stretched to the abdominal cavity. Generally, the uterus of the European bison is similar to that organ in domestic cows, however some differences were specified, may be related to a different lifestyle.
