Opis:
As there are different views concerning the relationship between branching type and timber quality, the present paper attempts to evaluate this relationship. The studies were carried out on 32 sample plots located within the boundaries of two natural ranges of Norway spruce in Poland: north−eastern and south−western. The selected trees were examined for the type of branching, height and diameter at breast height, timber quality, size classes or groups in a butt−end section, and kinds or varieties of wood defects having an effect on timber grade classification. The analyses did not show any clear relationship between branching type and timber quality of Norway spruce.

Opis:
The objective of the study was to determine whether differences exist between the selected characteristics of Norway spruce cones and seeds depending on their location in the crown. The study was performed in two spruce tree stands growing under mountainous conditions (the Beskidy Mountains, southern Poland). In winter 2015, the cones were collected from 60 standing trees located in the two selected seed stands – Ujsoły and Rycerka. From each tree, the cones were collected from three crown zones: top, central and bottom differing in terms of light conditions. Two characteristics of the cones and six characteristics of the seeds were analysed. To determine quantitative and qualitative traits of seeds standard methods for seed testing were applied. Significant differences between the populations were determined for cone weight and fraction of full seeds, weight of 1000 seeds and germination capacity. The crown zones differed significantly in terms of fraction of cones in the parts of the crown and mass of one cone as well as weight of 1000 seeds, germination energy and germination capacity. Moreover, a significant intra−population variation was observed for a majority of the analysed characteristics (fraction of full seeds, weight of one cone, weight of 1000 seeds, germination energy, and germination capacity). However, no statistically significant interaction between population and crown zone was observed. A significantly lower contribution of cones in the bottom zone of the crown may affect the economic viability of the commercial harvest. On the other hand some of the important seeds traits (e.g. weight of 1000 seeds, germination energy and germination capacity) were significantly better in the bottom and central part of the crown than in the top zone. There are no justified circumstances (both qualitative and quantitative) to perform the cone harvest only from the top zone of the crown.

Opis:
The main aim of this paper was to characterize Norway spruce clones in terms of bud burst, flowering and morphological features. Observation and measurements were carried out in the Norway spruce seed orchard of the Bielsk Forest District in the north-eastern part of Poland. The seed orchard was established in 1989 and consists of 428 grafts of over 37 trees from the Białowieża Primeval Forest. An assessment of bud burst, stem forking, stem form, crown width, branch thickness, vitality, flowering and fructification as well as diameter measurements was done in 2013 and 2014. The results showed variability of morphological features among different clones as well as within individual clones. Differences among clones in spring bud development, stem form and branch thickness were statistically significant. Additionally, a positive correlation between male and female flowering was observed. The research also confirmed an influence of the healthiness of the grafts on seed production with trees in a weakened state producing more seeds.

Opis:
The paper provides information concerning the growth of pine, spruce, oak, beech and fir stands based on the research conducted by the European Forest Institute in a number of the European countries and in Poland. Noteworthy i.a. is the increase in volume increment of spruce and pine in some stands in Germany up to 250% of the values given in the yield tables. Since the early fifties of the past century beech and sessile oak in Bavaria have exhibited an increase in the height growth and volume increment. Their values markedly exceed those provided in the tables. Fir, similar to spruce, pine and beech shows the reduction in the increment and dieback in the regions under heavy industrial pollution. However in other regions under the impact of air pollution the response of pure and multispecies stands with the share of fir was positive. In Poland, a rapid decline in the dbh increment in three tree species (fir, spruce, pine) in the seventies was greater than in the sixties. In 1981−1989, fir showed a favourable growth in diameter; this positive tendency was noticed in the whole range of fir distribution in Poland, though the increment did not return to the level before its decline. The pine increment regenerated after 1990. The poorest increment was found in spruce in the eighties following its collapse in the seventies (Żywiecki and Śląski Beskid).

Opis:
Eric The Red’s Land cannot be found on contemporary maps. There are not many older cartographic publications in which such an area would be marked either. They were published in only one country, Norway, and for a limited time. This was the result of the territorial claims that Norway reported to parts of eastern Greenland. To locate the area in geographical space, the name of Eric The Red’s Land was used (Norwegian: Eirik Raudes Land). Norwegian claims to East Greenland met the strong opposition of Denmark. In the interwar period, it seemed that the verdict of the Permanent International Court of Justice in The Hague, adopted in 1933 and recognizing Denmark’s sovereignty over all of Greenland, had ended the dispute. However, during World War II, Norway raised the issue of the possession of eastern Greenland again. This happened at a time when both Nordic countries were occupied by Germany. The cooperation with Germany undertaken by “Arctic expansionists” ultimately intersected with Norwegian ambitions in the eastern part of Greenland.

Celem zaprezentowanego w tym miejscu eseju jest zapoznanie czytelnika polskiego z, niestety niedocenianą nadal, architekturą krajów skandynawskich i Finlandii w dziewiętnastym stuleciu. Podstawową trudnością niniejszego opracowania pozostaje nader skromna, wręcz uboga, baza źródłowa w literaturze polskiej o neoklasycyzmie, historyzmie i eklektyzmie w tym regionie północnej Europy. Tym problemem interesował się niegdyś Piotr Krakowski, współtwórca, wraz z Zofią Ostrowską-Kębłowską, podwalin wiedzy na temat środkowoeuropejskiego historyzmu i eklektyzmu. Przedmiotowy esej jest przeto hołdem złożonym pamięci Profesora Piotra Krakowskiego, który onegdaj zachęcił niżej podpisanych autorów do wypełnienia znaczącego naukowego niedostatku wiedzy o architekturze tego obszaru kultury europejskiej.
The aim of this essay is acquainting the Polish leader with the still not sufficiently appreciated architecture of the Scandinavian countries and Finland in the nineteenth century. The basic diffi culty in this study has been an extremely limited, not to say poor, resource base in Polish literature concerning neo-classicism, historicism and eclecticism in that region of northern Europe. The problem was once of interest to Piotr Krakowski who, together with Zofi a Ostrowska-Kębłowska, created the foundations of knowledge concerning the centralEuropean historicism and eclecticism. The current essay is therefore a homage paid to the memory of Professor Piotr Krakowski who once encouraged the authors of this article to fi ll in the signifi cant scientifi c gap in the knowledge regarding architecture of this area of European culture.

Opis:
The aim of this research was to determine the composition of microscopic fungi colonizing Norway spruce dead wood depending on the degree of decomposition of wood and the location in the Tatra National Park (TPN; southern Poland). The work included lying and standing dead wood of Norway spruce as well as tree stumps. The sampling plots were located in the Białka Valley (eastern part of the TPN) where the forests are unmanaged and area is mostly under strict pro− tection, and in the western part of the Park, in the Chochołowska Valley, where the majority of forests is privately owned and managed (landscape protection). Samples were collected three times in the growing season, in spring, summer and autumn 2016. The sampling plots were located in the forests covered by different forms of protection: strict, active and landscape. The dominant microscopic fungi inhabiting analysed Norway spruce dead wood in selected regions of the Tatras are fungi belonging to Trichoderma genus: T. harzianum: T. polysporum, and T. hamatum. A much greater diversity of fungi species isolated from the dead wood was found for the Białka Valley, subjected to strict and active protection, than Chochołowska Valley, where forests are subject of the economic utilisation. More species and colonies were obtained from lying and older dead wood than from the stumps in the higher classes of distribution.

Opis:
On the basis of sectional measurements of diameters of trees from 5 sawtimber spruce stands in the Beskid Śląski and Beskid Żywiecki, a non−linear shape model for spruce stems has been developed using a trigonometric model [Bi 2000]. Subsequently, the accuracy of the proposed solution has been evaluated and compared with the accuracy of a linear model [Socha 2000]. The discussed non−linear model for describing the shape of stems is quite satisfactory, however, with regard to the accuracy of the determination of the stem morphological curve and volume this solution is inferior to the linear model.

Opis:
In recent years, we face a massive dieback of Norway spruce stands in Poland. The cause of this process may lay in the way of their monocultural silviculture. The correct assessment of the habitat conditions and soil properties in particular is the basis of the proper management of these forest areas. The aim of this study was to verify application of the trophic soil index for mountain areas (SIGg) in the assessment of site conditions for spruce stands with different health condition. Three types of spruce stands were distinguished: degenerated, weakened and stable. In total, 32 study plots were established in following forest districts in southern Poland: Ustroń, Wisła, Bielsko, Węgierska Górka, Jeleśnia, Ujsoły and Lądek Zdrój. The SIGg was calculated on the basis of <0.02 mm fraction content, the sum of exchangeable base cations, soil acidity and the total content of N and organic C in the humus−mineral horizon. These attributes are useful to determine the potential productivity of the soils did not differentiate visibly the analyzed stand variants. The soil in degenerated and weakened spruce stands showed higher degree of acidity and less the content of base cations compared to soils of stable spruce stands. Mountain trophic soil index can be applied in the assessment of the forest sites potential. Although it does not enable to monitor the disturbances in the nutrients circulation, the detailed analysis of its components allows for precise assessment of the forest sites status.

Borregard pipe traps baited with synthetic pheromone Duplodor (Chemipan, Poland) were installed on 70 locations situated above 600 m a.s.l. in Carpathians and Sudeten. The occurrence of I. duplicatus was confirmed in 17 locations in the western part of Carpathians, including those located around 1000 m a.s.l., while no beetles were caught in the eastern Carpathians nor in the Sudeten. The distribution range in Polish mountains is adjacent to those in northern Slovakia and northern Moravia (Czech republic).

Opis:
Based on participant observation and ethnographic interviews with Polish women working in kindergartens in Norway, this article studies the migrant women’s employment trajectories, including adaptation processes in the workplace and integration into the wider Norwegian society. In this paper, I aim at answering the following questions: How do Polish migrant women go about seek-ing employment in Norwegian kindergartens? How do they adapt to the new work environment? How do they deal with cross-cultural differences in childcare? How did they learn new norms and values within the institutional context of kindergartens? The research indicates that employment in kindergartens was not merely a way to provide for one’s livelihood, but was also a mechanism to establish and develop a closer relationship with members of the Norwegian society, a tool facilitating meaningful connections with the new country.

Opis:
At the end of 2013, Norway spruce stands in the area of the Tatra National Park were severely damaged by strong storms especially in the Kościeliska Valley region. In the following spring of 2014, a survey recording the occurrence of the spruce bark beetle Ips typographus (Coleoptera, Curculionidae, Scolytinae) was initiated in order to describe the dynamics of beetle reproduction in relation to protection measures executed in wind-damaged stands. Ten research plots with 20 trees each were established in a so-called active protection zone, where the broken and fallen trees had been processed and removed in 2014, and in a passive protection zone, where no actions were taken, and the dynamics of Norway spruce mortality due to bark beetle infestation including quantitative parameters (infestation density, sex ratio of beetle populations) were examined. The entomological analyses were performed on 25×25 cm large bark samples taken from four (active zone) or two (passive zone) tree sections. In the first year of the survey, no infested standing trees were recorded on the plots and the colonisation of fallen and broken trees was very weak. In the second year (2015), infestations appeared in larger numbers on the plots with passive compared to active protection but the infestation density was 0.89 mating chambers per 1 dm2 regardless of the protection status. In the third year (2016), most of the remaining living spruces had been infested with a mean density of 0.82 m.ch. per 1 dm2. In 2015, the proportion of females in the beetle population was 65.8% being higher in the active (68.4%) than the passive (64.0%) protection zone, while in 2016 the proportion was 63.5% and in this case slightly higher in the passive protection zone (63.9% as compared to 63.2%). These results are in accordance with patterns observed in wind-damaged Norway spruce stands of other areas in Poland and Europe and demonstrate the usefulness of forest management procedures in mitigating I. typographus outbreaks.
