Factors affecting selection of resting site type by pine marten in primeval deciduous forests (Bialowieza National Park, Poland)

The Number and Composition of Snags in the Pine-Spruce Stands of the Bialowieza National Park, Poland

This paper documents data on standing dead trees (snags) in the pine-spruce (Norway spruce Picea abies, Scots pine Pinus sylvestris) natural stand in Bialowieza National Park (BNP) in northeast Poland. Trophically, this mostly coniferous stand represents one of the poorest habitats of the BNP, and this stand has never been cut. There are few tree species of significance, i.e., Scots pine, Norwa...

Spatial Niche Segregation of Sympatric Stone Marten and Pine Marten – Avoidance of Competition or Selection of Optimal Habitat?

Coexistence of ecologically similar species relies on differences in one or more dimensions of their ecological niches, such as space, time and resources in diel and/or seasonal scales. However, niche differentiation may result from other mechanisms such as avoidance of high predation pressure, different adaptations or requirements of ecologically similar species. Stone marten (Martes foina) an...

Transect Studies on Pine Forests Along Parallel 52 ° North , 12 - 32 ° East and Along a Pollution Gradient in Poland : General Assumptions

The responses of pine forest to changing climate and environmental chemistry were studied along two transects following the pollution and continentality gradients in Poland. One axis begins on the western border of Poland, crosses the country along the 52nd parallel, and ends on the eastern border of Poland in the area of Bialowieza National Park, Biosphere Reserve. The second axis begins in in...

Ramification of Celiac artery in the pine marten (Martes martes)

The pine marten (Martes martes) is a medium sized carnivore rarely found in Iran. The aim of this study was to describe species-specific characteristics of the celiac artery in pine marten. In pine marten examined in this study, it was observed that the celiac artery originated from the ventral aspect of abdominal aorta. The celiac artery was divided into two branches. A thick branch was the co...
