The identification of fungal species in dead wood of oak

Background. The wood of dead, dying and living trees is a very important element of the forest ecosystem. The existence of many species of fungi is closely related to the presence of dead wood in the stand. The fungi community is a group of different species occurring in a certain time and space. The species composition of such a community is not constant and changes with the passage of wood into successive stages of decay. The impact on the formation of the fungi communities has a primary species composition occurring on and in the wood. The first wood is populated by species capable of decomposing fresh wood, then penetrating the structure of wood already violated, and in the final stage, settling on wood that is heavily decayed.
The aim of this study was to evaluate the species composition of fungal communities on pedunculate oak Qu- ercus robur L. wood. The material was downloaded from the area of the Drawa National Park (from 15°45’ to 16°45’E, from 53°00’ to 53°15’N) and divided into three stages of wood decomposition.
Methods. The detection of fungi was done, using the method of molecular biology. The use of molecular methods was based on polymerase chain reaction (PCR), cloning and sequencing by method described by Method of Sanger. The resulting sequence was compared with the reference sequence from the NCBI database.
Results. The species composition of communities differed between various stages of decomposition. The most numerous was represented by Ascomycota. When analyzing the first stage of decomposition, 25 clones were obtained which represented three taxa. In the second stage 32 clones were obtained which represented 5 taxa. In the case of the third stage of decomposition, a positive result was not achieved. The taxonomy common in and with the II degree of decomposition was Ophiostoma novo-ulmi. The differences in the spe- cies composition between the species that settle the individual decomposition levels indicate the succession of species during the decomposition of wood. Except for species associated with wood degradation, these observed species have no significance for forest management.

The purpose of this thesis was to analysis changes in forests managed by the State Forests National Forest Holding based on indicators for sustainable forest management in the years 1993–2013. Diagnostic variables have been normalized using the zero unitarization method. Application of a synthetic indicator has allowed of evaluation of changes over time by one value. In the analyzed period it saw positive developments. They reflect the progress in the implementation of sustainable development in forestry.

Research was conducted in the Giant Mountains within the highest region of the Sudeten. In the period of 2014–2015 a total of 3590 larvae and imagines representing 62 species of Trichoptera were caught from 20 location sites of 8 streams flowing in the Karkonosze National Park (KNP). Some species were new for the Giant Mountains and one of them – Hydropsyche tenuis Navas, 1932, was a novel form within the fauna of Poland. There was a substantial group of typical species for mountain and highland regions. In the collected material relatively few species require higher pH values as opposed to species with higher tolerance to acidifi- cation of water. The obtained results are comparable with the results for the Babia Góra, as well as with those obtained for the Czech part of the Giant Mountains. The species composition and the relatively low density of Trichoptera larvae living in the studied streams testify to the specificity of the waters in the KNP.

Introduction. Porodaedalea pini (Brot.) Murrill often occurs in Scots pine stands, whereit is a constant threat and causes significant losses of wood raw material.
Objective. It is difficult to clearly determine why in some regions of the country the fungus is more often found, therefore it was decided to determine the effect of temperature on the distribution of pine wood by Porodaedalea pini. This experiment was also used to determine the change in pH of the wood.
Methods. Five variants of the experiment were used: 1. temperature 21°C in total darkness; 2. temperature 21°C in day/night conditions; 3. temperature 14°C in total darkness; 4. temperature 4°C in total darkness; 5. natural termo-period (field conditions) from March 1 to August 31.
Results. In all the variants studied, the fungus caused the decomposition of wood. It was shown that the result of the experiment was influenced most by the thermal and light factors than the individual characteristics of the fungal isolates. By spreading the wood, the fungus lowered the pH. The thermal conditions prevailing in Poland with an average annual temperature of 6–8°C favour the development of the P. pini, which is able to develop at a temperature of 4°C. Taking into account the distribution of tree stands in Poland with a high degree of infection by P. pini, it can be assumed that the temperature does not affect this state of affairs.

Introduction. Porodaedalea pini (Brot.) Murrill is a fungus in pine stands, where it is a permanent threat and causes significant losses of wood raw material.
Objective. The purpose of the work was to determine the size of economic losses in forest management re- sulting from the development of P. pini in pine stands, as well as to determine the calorific value of infected wood.
Methods. Field research was carried out in the area of the Forest Districts: Miastko, Tuczno, Gościno, Du- rowo and Łopuchówko.
Results. The percentage of wood with rot on the research plots ranged from 0.31 to 2.16, which translated into a financial loss at the logging area from 212.35 to 4315.31 PLN. It is estimated that in 2017, losses due to the occurrence of pine forests could amount to PLN 75 million. There was no decrease in the calorific value of the wood tested.

Admission. The paper presents an analysis of selected dendrometric features of European ash growing on the forest site types belonging to the fresh broadleaved forest, moist broadleaved forest, riparian forest and alder-ash forest. The aim of the research was to determine the impact of habitat diversity on the formation of breast height, height and slenderness of the species in question.
Material and methods of research. The research material was collected on four chosen areas representing different habitat conditions, located in the Babki, Konstantynowo, Łopuchówko and Poznań Municipal For- est Districts. In tree stands belonging to the fourth age class, research areas of 25 ar were established. Trees belonging to the 1st and 2nd Kraft classes were selected for the measurements. Then tree height and diameter at breast height of ash were measured. Basic statistical characteristics were calculated and a one-way analysis of variance was carried out due to the forest site type of the given stand.
Results and conclusions. The analysis showed the diversification of selected dendrometric features of European ash depending on the forest site type.

The aim of the study was to verify the hypothesis that the quality of male red deer hunted in the Opolskie region depends on selected characteristics of the place of their earlier habitat (forest cover) and the age of the individual. Weight of both carcass and antlers was adopted as a criterion. Material consisted of carcasses and antlers of 2018 red deer harvested in 119 hunting districts in the Opolskie region in 2011/12−2013/14. As a result it was found that the individual quality of male red deer was differentiated. Forest cover and age of individuals (Fig. 3) had significant impact on it.
Red deer hunted in the field-type hunting districts were significantly heavier than red deer hunted in the forest-type hunting districts (more than 40% forest cover). The average carcass weight in the field-type hunt- ing districts amounted to 113.5 kg and was nearly 6 kg higher than in individuals hunted in the forest-type hunting districts (107.7 kg). Between the mean values obtained for the body weight of male red deer hunted in the field-type and forest-type hunting districts showed a statistically significant difference in the first five age classes, ie. from 2 to 10 years of age. The body weight of the oldest “field” and “forest” individuals was similar.
In each class of age the weight of antlers of red deer hunted in the forest-type circuits were lower than re- sults from the field-type circuits (Fig. 3). The biggest differences were reflected in individuals 8–10 year and reached 0.35 kg. Weight of antlers of red deer hunted in both circuits were growing to the last age class. The culmination of this feature occurred in individuals 11 years and older. As a result of Student’s t test was statis- tically significant (p < 0.05) in the four age classes (2–5) in individuals from 3 to 10 years old. In individuals 2 and 11-year-old and older antler mass was not significantly differentiating feature (Table 1).
