The results of these genetic studies should be included in breeding programmes aimed towards saving the contemporary genetic variability of the species. These should also include studies of daily and seasonal activity rhythms, seasonal migration and habitat preferences. There the concern is to raise up the low sex ratio in order to balance the population by sex. Estimated posterior probabilities for the distal tibia breadth. Special attention should be paid to the behaviour of European bison towards people, forestry and agricultural activities, particularly in densely populated areas. It can be shown mathematically that a frequency that any given sample is more likely to have come from some distribution of a species comprising half males and half fe- populations than from others. A thorough and more critical analysis of the current state of the species reveals serious threats stemming mainly from its genetic structure and from its management. Wilson and Reeder In many regions inhabited by bison in historical times, the thickness of snow cover exceeded that value e.
The most common Prummel and Frisch, However, stating that the European bison is completely safe would be rather premature. The process of extinction started from the west, the south and the north. The values are utilized to estimators of the parameters. Little information is available on the populations inhabiting the Caucasus Mountains Russia or the Carpathians Poland, Ukraine. They also do not conform a natural mortality profiles distribution lays between these values. As a consequence of passing a dramatic bottleneck, the gene pool is limited and animals are highly inbred. Since then, the Method of The problem of choosing groups that have the same vari- the Moments, with simplified versions, has been used as a ances or different variances can be solved by forming the preliminary approach to derive the parameter estimators statistic Ghose, ; Josephson et al. There is a serious need to assess the present genetic variability for the whole world population. Journal of Anthropological Archaeology 9, — During that period, a handful of ranchers gathered remnants of the existing herds to save the species from extinction. The maximum cow home ranges cover approximately km2. Journal of groups and their needs, according to the kind of settlement and Theoretical Biology , — Reconstructing cave bear Monchot, H. Usually, home ranges of European bison do not cover the whole area of a forest complex cf. It is given by Arago cave Tautavel, France is a well-known paleoanthro- pological site. During the last glaciation c. Journal of the American Statis- Pleistoceno medio de los Pirineos: They also graze in hilly or mountainous areas where the slopes are not steep. Estimated posterior probabilities for the distal tibia length. Current legal status of the species in each European country will be published soon by the regional offices. This chapter lists the problems that remain important for extending our knowledge on the species, its recovery and management, and aims to encourage bison specialists to solve them. All rights of reproduction in any form reserved. Although their fossil records are far rarer than their antecedent, they are thought to have existed until at least 36, BCE. Low temperature and long-lasting snow cover delimit European bison mobility in winter. They survived in enclosures in Kreyern and later in Liebenwerda until
