Opis:
The lack of knowledge about seasonal dynamics and impact of deer browsing on deciduous saplings in plantations in managed forests in Poland raises difficulties in assessing the impact of cervids on forests and in selecting effective methods for protecting plantations against damage caused by deer. The studies covered 1129 saplings of sycamore, oak, beech, linden and birch species that were planted on the unfenced sites accessible for animals and fenced sites left for comparison.

Opis:
Progeny of four adult silver firs, which were an admixture in Norway spruce (Picea abies) stand was, analyzed. The study was done in lower mountain zone of the Karkonosze (Giant Mts.) National Park (SW Poland). The seedlings occurred in two clumps related to the position of adult trees, whereas spatial pattern of the seedlings inside each clump was random. The seedlings were spaced mainly in distances 5–25 from the nearest adult tree. The maximal distance was up to 50 m. Most seedlings were established in accordance with main wind directions. Also, in these directions seedlings were more distant from adult trees than in other directions. The seedlings grew in better light environment (12% of PPFD) than average (9,6% PPFD). This effect was statistically significant. The height increment of the seedlings was low and was not correlated with light conditions. Similarly, there was not any correlation between the apical dominance ratio and light. The lack of this correspondence we attributed to browsing. The silver fir seedlings were significantly underrepresented in patches of Vaccinium myrtillus, on raw needles, under crown of adult trees and in concave micro-relief form. The underrepresentation in the places covered by canopy and in patches of bilberry we related to the indirect effect of continuous browsing, which leads to higher seedlings mortality in more shaded places and sites of stronger competition between forest floor vegetation and silver fir seedlings.

The field study was conducted within an acclimatization enclosure in Radziejowa Valley and in a clearing in Tyskowa Valley, close to Baligród (Bieszczady Mts., south−eastern Poland) during two seasons: spring and summer. The aim of this study was to assess browsing intake by Polish koniks (tarpan type) in enclosures and free ranging conditions. The measurements were done along transects in the enclosure and around the clearing, inward of the forest stand. In all scenarios, koniks preferred shrubs (rose and plum) mostly avoiding trees. The amount of taken browse depended on the amount of preferred shrubs available.

Opis:
European yew (Taxus baccata L.) is a rare species, but is the focus of great interest because of the species recovery attempts and its use in medicine. The aim of this study was to determine the optimum conditions for the development of the young generation of this species. Four-year old yew seedlings were grown under artificial light reduction: 2, 8, and 30%, as well as in full light. The seedlings were then planted in natural conditions in fenced and unfenced areas. The results of six years field studies indicated that the greatest impact on survival was shown by the light conditions from the period before planting under the canopy of trees. Seedlings from the 2 and 8% of light showed the greatest mortality. The reason was the sudden change in light conditions, because at the time of planting (early spring), there was no reduction of light under deciduous trees. Almost all of the unfenced yew seedlings were grazed by deer, but yew survival in the unfenced group was surprisingly high despite the permanent grazing. This was explained by the high resistance of yew to cutting and the protection of seedlings by a dense layer of Rubus. The results indicated that yew trees require protection against animals for normal development, even if animals have not previously had contact with Taxus and that yew seedlings are very sensitive to sudden changes in light. Both conclusions can be applied in the development of natural and artificial regeneration of European yew and other endangered plants.

Opis:
The Recent rapid growth of the information technology aid people to improve the performance in processing their job activities. These changes, in turn, force them to carry out their job activities using computers in the workplace; that results in the increase of somatic and/or mental stresses. In this study, we conducted a preliminary experiment to estimate an impact of web-browsing on human mind and body. Two types of web-browsing tasks, which are a 18-minuetes of continuous web-browsing and an intermittent web-browsing (first 45 second of each 1-minutes interval), were given to the subjects (10 healthy male aged from 20-23) with within-subjects experimental design. With regard to physiological measures, two prominent stress biomarkers, salivary immunoglobulin A (IgA) and cortisol, were employed. Comparing among the task conditions, relatively larger and long-lasting increase of IgA and smaller decrease of cortisol was observed with an intermittent web-browsing despite there was no difference in the psychological state. These results illustrate the difficulty of estimating the mental workload caused by web-browsing and the importance of employing physiological indices.

The role of readership and experience is declining. Collective identity is reflected by electronic texts. They show different identities: civilizational, cultural, religious, national, family, gender, professional, artistic. Cultural texts, however, are removed from their native contexts and recycled. Fast browsing of digital resources limits emotional experience. Social media limit the interactions of users to only six conversational archetypes. People are unable to function creatively in the poorly understood interactions. The collective identity on the Internet is molded by digital texts.

Opis:
Assessment of the impact of large herbivores on young generation of trees in the protected forests can support decisions about whether to intervene in natural ecosystems (e.g. individual tree protection, animal culling) or not. A study on the condition of forest regeneration, including the assessment of the damage caused by deer, was performed in the Gorczański National Park (GNP; southern Poland) in 1993 for the first time. The inventory was repeated in 1996 and 2011 on the same 415 concentric permanent sample plots located in the centers of 400×400 m grid. Trees with diameter <16 cm or height 1.3 m were counted. The impact of deer was assessed using: (i) the share of browsed terminal shoots in h=0.3−1.3 m class trees and the tolerable (based on a reference) share of browsed trees of such height with the most damaged tree species taken into account and (ii) the proportion between the density of recently (the previous year) debarked, frayed or broken trees and the tolerable (based on a reference) density of such trees. The main interpretation unit was composed of all stands in the GNP, while stands in particular protection districts formed lower level. Over the time, the density of trees in the regeneration layer increased (fig. 1). The density of recently debarked (frayed or broken) trees decreased considerably (fig. 2), even if a large number of trees (especially silver fir) with old wounds existed (fig. 4). The density of the browsed trees remained more or less unchanged. This type of damage most frequently affected silver fir, sycamore maple and rowan (fig. 3). Differences between the level of forest regeneration damage in different protection districts of the GNP remained similar (fig. 5). The deer impact assessed on the basis of the density of debarked trees significantly decreased to be classified as tolerable in 2011. However, the impact assessed with the share of trees with the browsed terminal shoot did not reach the tolerable level in one protection district. Results show that measures undertaken to protect forest regeneration produce a partially positive effect. The browsing level was still too high. Differences in the deer impact on the forest regeneration between protection districts can be considered as permanent ones.

Celem niniejszej pracy jest ocena aktywności żerowej jelenia europejskiego na łąkach śródleśnych poddanych renowacji z wykorzystaniem różnych metod. Badania przeprowadzone na obiektach doświadczalnych wykazały, że zdecydowana większość aktywności żerowej zwierząt miała miejsce na powierzchniach odnowionych przy pomocy metody pełnej uprawy połączonej z wysiewem specjalistycznych mieszanek nasiennych. Stosunkowo niewielki efekt dało zastosowanie metody podsiewu. Żerowa-nie na obiektach kontrolnych miało charakter incydentalny, co pozwala wnioskować, że ruń tych powierzchni łąk nie spełniała wymagań pokarmowych jelenia europejskiego.
Aim of this study is evaluation of red deer foraging activity on renovated mid-forest meadows using different methods. Research, carried out on experimental sites, showed, that most of grazing activity of animals falls on areas renovated by full tillage method combined with sowing of specialised seed mixtures. Relative low effect occurs by using of oversowing method. Foraging activity on control areas was very low, this allow to conclude that sward of this mid-forest meadows didn’t fulfil nutritional needs of red deer.

Opis:
The results of the inventory of damage caused by roe deer in a 2−year−old apple orchard in central Poland permitted to evaluate the browsing intensity as well as the relationship between biometric characteristics of trees and browsing intensity. The research showed that damage caused by the roe deer was mainly caused by shoot browsing, then rubbing the velvet antlers against trees and bark stripping. In one winter, roe deer damaged 35% of the orchard by browsing even up to 100% shoots on an individual tree. Significant differences were found between the intensity of browsing the different varieties of apple trees. The largest damage was noted in the case of the Ligol variety (35% of shoots on average), while the smallest – for the Idared and Golden Delicious varieties (approximately 5% of shoots on average). Branching and tree height were not found to affect the level of damage. When establishing forest hunting grounds, the Ligol variety, eagerly browsed by roe deer, should be planted on browsing plots, while Idared and Golden Delicious varieties – in orchards designed for fruiting.

The study assessed the intensity of Polish konik browsing in mixed coniferous forest (BM), alder swamp forest (OL) and pine swamp forest (BB) of different canopy closure and shrub or ground vegetation cover. The study was conducted in Polish konik enclosure situated in the Roztoczański National Park (eastern Poland) in August 2011. We examined mean browsing intensity and the tendency of horses to browse along 100 m zone from the pasture. The field study was conducted at three parallel transects set in 40 m intervals in each analysed forest habitat, starting at the forest edge and oriented towards the forest interior. Along the transects, 5×2 m plots were established in 10 m intervals. Within each plot the untouched current twigs and twigs browsed by koniks (up to 2 m above the ground) were counted separately, and categorized by a tree and shrub species. For each species 30 samples of complete twigs and twigs browsed by koniks were collected. Twigs were dried by 72 h in 60°C and weighted with accuracy up to 0.001 g. We estimated the dry mass of shoots available within the plot and taken by horses. Generally, koniks were using each studied forest stand proportionally to the mean browse mass. A factorial regression indicates that regardless to the available mass in a given forest stand, horses foraging intensity towards the forest interior was varying significantly. Koniks entered further into the forest the more willingly the more open the forest canopy was. Openness of the forest habitat could indirectly influence the pattern of forest penetration by horses, because of the grazed ground vegetation there.

Opis:
Effects of ungulate pressure on the development of young generation of trees is one of the most important issues in ecology and forestry. Ungulate pressure influence on the development of natural regeneration has been also reported from several national parks. Our study on the effects of ungulate browsing on the young generation of trees was conducted on more than 500 sample plots controlled during one growing season. The overall browsing pressure ranged from 7.6% in seedlings to 20.3% in low saplings. The pressure of ungulates on the regeneration of Picea abies, the dominant species in the Tatra National Park, was by and large below 1%. Broadleaved species were browsed more frequently. The relationship between the plot altitudes and browsing intensity was statistically significant for seedlings and low saplings; at the higher altitudes, the browsing pressure was greater. There was also observed a statistically significant relationship between the type of former management and the browsing degree in seedlings; in the areas subjected to “landscape protection”, the intensity of browsing was higher when compared to strictly protected areas. Pressure exerted by ungulates on tree regeneration was very unevenly distributed, i.e. some plots were heavily browsed and many others - not browsed at all. The most affected tree species were Salix caprea and Sorbus aucuparia, although the percentage of browsed individuals rarely exceeded 50%. Other species favored by ungulates was Acer pseudoplatanus; despite the high browsing pressure, this species was present among seedlings and tall saplings, suggesting that it would be able to recruit to the tree layer. Abies alba was browsed less frequently than the deciduous trees; however, among the tall saplings it was the third most browsed species.
