The presence of sacral furniture in social life in Poland is a universal phenomenon, exerting influence on the development of material and spiritual culture. The paper attempts at identifying the most important ergonomic and socio-economic factors determining the functionality of wooden pews used in Poznań, the capital of the oldest Polish diocese of the Roman Catholic Church. Hence, statistical relations...
The swine RYR1 (ryanodine receptor 1) gene is a major gene for meatiness, but its effect on the fatness and location of fat deposition is less known. A known mutation in this gene is responsible for a drastic deterioration of meat quality. We provide evidence that the mutation (c.1843T) alters FAT distribution between back fat and abdominal fat, which are of different value in meat processing.The...
Armillaria root rot is one of the most important diseases in Polish forests. Study assesses if mycelium mixed with soil and metabolites of antagonistic Trichoderma reduce the occurrence of Armillaria. No influence of Trichoderma on the growth of Armillaria ostoyae rhyzomorphs and mycelium was found.
Fungi play an important role, as by decomposing dead organic matter they contribute to the carbon cycle in nature. Apart from this beneficial effect, fungi in forest ecosystems cause diseases of deciduous trees. Stumps, being remnants of stems left after felled trees, provide nutrient resources for various organisms, including fungi causing the most dangerous diseases of forest trees such as Armillaria...
The aim of this work was 1) to investigate the genetic diversity of H. annosum s. str. populations, 2) to recognize genets ability of their aggressiveness to Scots pine. The genetic similarity among genets varied from 0% to 74%. Totally different genets were found in 17.9% of cases. The lowest similarity occurred among 20.7% of genets and it was calculated on 18%. Six months after inoculations of...
One of the methods limiting the damages done by Armillaria species is to decrease the number of dead wood stumps attacked by it, particularly it refers to deciduous tree stumps.The objective of the presented paper was an attempt to estimate the possibility to select some saprotrophic fungi species whose ability of decaying oak wood is higher and faster than that of Armillaria ostoyae (Romagn.) Herink...
The objective of the study was to assess the mortality risk of David’s deer associated with climatic conditions by the use of hazard function within clustered populations and according to place of birth. Additionally, the inbreeding level was examined within each cluster. Records were considered of 1192 individuals born in 56 zoological gardens in the years 1947-2000. Censored data (animals which...
Background. Constant improvement of animal feed formulas calls for new raw materials. In the feeding of fish, one of diet recipe optimization methods is to search for feed protein sources alternative to fish meal. The presently reported study focuses on an unconventional protein source—the erythrocyte meal—for feeding fry of common carp. Materials and Methods. The barothermal method (extrusion) was...
Survival and hazard functions supply suitable information concerning changes in the population dynamics, especially in the case of species that are not subjected to artificial selection. One of such species is David’s deer (Elaphurus davidianus Milne-Edwards, 1866) that underwent a dramatic reduction in the population size in the first years of the XX century, but has been subsequently restored from...
