Opis:: The study was conducted in an old, historical park, in the northern part of Stalowa Wola city (south-eastern Poland). The aim of the study was to investigate the diversity of moss-inhabiting diatoms of the white poplar (Populus alba L.) bark. During the study, a total of 47 diatom taxa were found, three out of which were considered as dominant. Three other species are mentioned in the Red List of the Algae in Poland: Achnanthes coarctata (Brébisson) Grunow, Luticola acidoclinata Lange-Bertalot and Stauroneis thermicola (Petersen) Lund. For three species: Luticola sparsipunctata Levkov, Metzeltin & Pavlov, L. vanheurckii Van de Vijver & Levkov and Hantzschia subrupestris Lange-Bertalot, this is the first report from Poland.

Opis:: The distribution and occurrence of polyisoprenoids (dolichols and polyprenols) in the leaves and roots of nine true Okinawan mangroves and the leaves of one associate mangrove were analyzed using two-dimensional thin layer chromatography. In the leaves, the distribution of three types (I, II, and III) of polyprenols and dolichols were detected. (I) The predominance of dolichols over polyprenols (more than 90%) was observed in Avicennia marina, Bruguiera gymnorrhiza, B. gymnorrhiza (yellow leaves), and Rhizophora stylosa. (II) The occurrence of both polyprenols and dolichols is observed in Excoecaria agallocha, Kandelia obovata, K. obovata (yellow leaves), Lumnitzera racemosa, Pemphis acidula, and Sonneratia alba. (III) The predominance of polyprenols over dolichols (more than 90%) is observed in Heritiera littoralis and Hibiscus tiliaceus. However, in the roots, a type-I distribution was observed in A. marina, B. gymnorrhiza, E. agallocha, H. littoralis and S. alba. A type-II distribution was observed in K. obovata, L. racemosa, P. acidula, and R. stylosa with no type-III distribution. The chain-length distribution of dolichols in the leaves and roots was C50–C140 and C60–C120, respectively. A similar chain-length distribution of polyprenols of C45–C140 and C65–C85 was detected in the leaves and roots respectively. Taken together, sixteen out of twenty-one tissues indicated that dolichols are more abundant than polyprenols in both leaves and roots. The present study is the first to clarify the diversity of polyisoprenoids in both the leaves and roots of mangrove, suggesting the chemotaxonomic significance of polyisoprenoids in the mangrove tree species.

Opis:: We have investigated genetic diversity and the mating system of Scots pine plus trees from the Tuchola Forests – Poland, using allozymes as genetic markers. The studied plus trees possess high genetic diversity (expected heterozygosity He = 0.427) and low inbreeding (Wright’s index F = –0.028), which is comparable to Scots pine trees observed in other studies in natural populations and seed orchards. The mating system analyses revealed that almost all offspring produced by the plus trees were due to outcrossing (tm = 0.983), with no apparent bi-parental inbreeding. The estimate of correlation of paternity indicated that each of mother trees is pollinated on average by a relatively large number of effective males (Nep = 30.3). The observed genetic diversity and mating system patterns indicate that the seeds produced by the studied plus trees possess high genetic variation needed in reforestation processes.

Opis:: One of the functions of roadside tree planting is biodiversity protection. The analysis often alleys from Lower Silesia region confirmed their floristic wealth. Nineteen tree species and five shrub species were recognized. Planted species forming alleys are predominant among sites was different, but two alleys attract an attention with their compositional arrangement: chestnut lane in Staroscin ended with a group of old, monumental oaks surrounding a historic figure, and two-part lane in Biestrzykowice. The cherry alley in Dąbrowa Namysłowska should be covered by a special care since there are less and less alleys of this type. Floristic diversity may be seen especially clearly in the case of roadside herbaceous plants. In all analysed sites 123 species of herbaceous plant belonging to 32 families were recognised. The number of individuals from particular families was varied. The most abundant were aster family (Asteraceae), blue grass family (Poaceae) and pea family (Fabaceae). High diversity is also confirmed by the fact that only two species were present in all ten alleys, while as much as 49% of species were observed once only. Among recognized species, the predominant are those characteristic for roadsides, however also another ones from neighbouring areas may be found. The alleys may also be a place of protected species occurrence bear's-garlic ( Allium ursinum) or ones characteristic for quite other kinds of sites triangle pink (Dianthus deltoides).

Opis:: Village Common Forests (VCF) are used sustainably for water source conservation, livelihoods and other biomass needs ofethnic communities in the hilly areas of Bangladesh. The current forest degradation rate warrants the importance and potentiality of VCF for sustainable natural resources management. This study was conducted in two VCF of Lama and RumaUpazila at Chimbuk hill range in Bandarban district to explore the indigenous management techniques and tree species diversity. To identify tree species diversity, eighteen plots (9 plots from each VCF) were selected at different hill position (top, middle and bottom) by stratified random sampling method with the dimension of 20m×20m per plot. Shiner-winner and Simpson index were used to calculate the tree species diversity. According to the analyses, it was found that diversity was higher in top of the hill, but species density (stem/ha) was higher in the valley. It was also found that 23000 seedlings/ha regenerated naturally and among the 31 identified families, Moraceae was dominant where the density was 354 stems/ha with basal area 52.63 m2/ha. The dominant species were Schleicher oleosaand Anisopterascaphula and important non-timber species were Melocannabaccifera and Calamusgurubagrowing abundantly in the study areas. It was observed that the VCF were managed by ethnic Mro community with two different committees (customary and executive) who made some rules for natural forest conservation. This management practice is not only conserving hill forests, but also helping to improve degraded forest and create new habitats for biodiversity in the study area.

Opis:: The live and dead tissues, and trapped leaf litter by the epiphytic tree fern Drynaria quercifolia associated with riparian tree species of Konaje (west coast) and Sampaje (Western Ghat) streams of India during dry (summer) and wet (monsoon) seasons yielded 37 species of water-borne conidial fungi on bubble chamber incubation. Dead bracket leaves of fern possess the highest species as well as conidia in Konaje, while the trapped leaf litter in Sampaje. During summer, the diversity was highest in bracket leaves in both locations, while in monsoon season it was highest in rhizomes of Konaje and in trapped leaf litter in Sampaje. Even though the conidial output from tissues of Drynaria and trapped leaf litter were not equivalent to stream submerged leaf litter, the species richness ranged between 40% and 75% in Konaje and Sampaje streams. As stable epiphyte, Drynaria exposed to wet and dry regimes in tree canopies of west coast and Western Ghats likely to serve as host for perfect states of water-borne hyphomycetes.

Opis:: This thesis presents the research results on fruit tree alleys located in the area of Stare Czarnowo commune and their influence on the regional landscape diversity. Fruit tree alleys serve as a perfect landscape arranging component which orders the space and performs many natural functions. After the II World War trees were sparsely planted along the road sides and for over 60 years alleys they created have been thoughtlessly devastated. Few of them remained until today, mainly in the West Pomeranian district. In the territory of Stare Czarnowo there were 8 fruit alleys of a different habitat to select and take stock of. Among them: woodlots, roadside shrubs and the avenue created in the area of Dendrological Garden in Glinna. Specimen considered for the research had to be at least 30 cm in the trunk circumference. Among 374 of stock taken plants 4 were identified as fruit trees. There were 125 specimen of the size qualifying them to be regarded as the nature monuments. Fruit trees alleys have a huge impact on diversity of natural habitat. Due to its historical grounds they should be more often and widely used in shaping the rural landscape.
W pracy przedstawiono wyniki badań nad alejami drzew owocowych zlokalizowanych na terenie gminy Stare Czarnowo oraz ich wpływem na waloryzację krajobrazu regionu. Aleje drzew owocowych stanowią doskonały eksperyment kompozycyjny, który porządkuje przestrzeń oraz spełnia wiele funkcji przyrodniczych. Po II wojnie światowej rzadko sadzono drzewa owocowe przy drogach, a przez ponad 60 ostatnich lat bezmyślnie niszczono utworzone z nich aleje. Nieliczne z nich utrzymały się do dzisiaj, m.in. w województwie zachodniopomorskim. Na terenie gminy Stare Czarnowo wytypowano i zinwentaryzowano 8 alei różniących się typem siedliska. Wytypowano aleje śródpolne i przydrożne oraz aleję utworzoną na terenie Ogrodu Dendrologicznego w Glinnej. Do badań wzięto pod uwagę jedynie okazy o obwodzie pnia minimum 30 cm. Wśród 374 zinwentaryzowanych roślin zidentyfikowano 4 gatunki drzew owocowych. Odnotowano 125 okazów o wymiarach kwalifikujących je do uznania za pomniki przyrody. Aleje drzew owocowych wpływają na różnorodność biologiczną obszaru, na którym występują. Ze względu na podłoże historyczne oraz swe walory estetyczne powinny być szerzej wykorzystywane w kształtowaniu krajobrazu obszarów wiejskich.

Opis:: Since several years already, a massive infestation of bark beetle has taken place in the Białowieża Forest, decimating a local Norway spruce population. In consequence, many open areas appeared, practically deprived of trees and other forest vegetation. The existence of such areas has a very negative impact on multiple values of the Białowieża Forest: natural, social, economical and landscape−aesthetic values. The local forest administration prepared a strategy aimed at active restoration of diverse woodland communities typical for the Białowieża Forest in all places, where bark beetle infestation wiped up the spruce stands. Those plans were criticized by representatives of the environmental organizations who blamed the foresters for transforming the Białowieża Forest into ‘plantation’ and claiming that such measures are inconsistent with the existing forest management and protection plan. The postulate of environmentalists is that the recovery of woodland communities should proceed completely naturally. Taking into account the above mentioned controversies, in this paper we examine the issue of natural regeneration in the Białowieża Forest in detail. In particular, we try to determine to which extent this method of forest reproduction enables re−establishment of compositionally diverse woodland communities, distinguished by a high level of biological diversity and able to provide a wide range of commodities and benefits important for today’s society. Based on an extensive literature review we show that a combination of different (abiotic and biotic) factors, influencing establishment and subsequent growth of seedlings and saplings in the Białowieża Forest has long been strongly unfavorable for many tree species. In this regard, one should particularly emphasize the negative role of large herbivores, especially red deer, which is present in the Białowieża Forest since the end of 19th century, when it became a private hunting ground for Russian tzars. The devastating effect of deer browsing on natural regeneration is a well−documented phenomenon and widely recognized problem in the forestry practice. The fencing of young forest generation against game pressure is an indispensable measure, needed to secure the continuous existence of several tree species (first of all those palatable and vulnerable to browsing). Very strong arguments for an active approach to the described problem delivers also a long−term study on natural forest dynamics conducted since 1936. It shows that under conditions of strict protection the regeneration capacity of the Białowieża tree species is very variable. These differences lead to the compositional simplification and impoverishment of many tree stands, with numerous negative consequences for local biodiversity. We underline that an active management strategy is a basic prerequisite for maintaining a diverse character of the Białowieża stands and their ability to provide all important ecosystem services on a sustainable basis. Such a strategy should include, beside of the phase of establishment, also the subsequent developmental stages of new forest generations. The general goal of such a strategy should be to secure a possibly high diversity of tree composition and to enable the development of tree species representing a full range of life−history strategies and playing different successional roles: from typical pioneer species, through intermediate, to climax species.
