Opis:
Plant diaspore dispersal is a fundamental process affecting the development of forest vegetation and its natural regeneration, especially with regard to typical woodland species, which spread slowly and form short-term soil seed banks. Most of these species have poor seed dispersal mechanisms, which is the major cause of their very slow expansion. The following questions were asked: (i) is there a relationship between the age of a woodland and the presence of forest vascular plant species representing different seed dispersal types; (ii) how do the proportions change between species representing different seed dispersal types in relation to the age of woodland; (iii) what factors determine the presence of species representing a given seed dispersal type; (iv) which factors affect the presence and which ones influence the abundance of selected woodland species? A multiple regression models were developed based on data obtained from 144 woodland patches designated for the study. A probit regression analysis was performed for selected species exhibiting various seed dispersal models. Woodland plants of all seed dispersal types show a significant relationship with the age of woodland, starting from the strongest linkage: anemochores, myrmecochores, endozoochores, epizoochores, barochores, autochores. As the woodland ages, the proportion of forest myrmecochores and anemochores grows, whilst the proportion of autochores, epizoochores and endozoochores shrinks. Results obtained indicate that the direct proximity of ancient woodland has a major effect on the occurrence of more poorly dispersing plants in recent woodlands, such as myrmecochores and heavy anemochores.

Opis:
A numerical analysis of the phytosociological relevés from ancient and recent woodland on a mesic forest site in central Poland was carried out. Three groups of forest stands were recognised: planted with Pinus, recent and ancient oak-hornbeam Tilio-Carpinetum. The species of ancient woodland occurred mainly in ancient oak-hornbeam forest stands, however some ferns: Dryopteris carthusiana, D. dilatata and D. filix-mas, and an orchid species Epipactis helleborine, are to be found mainly or exclusively in recent forests. The occurrence of ancient forest species in recent woods may be putatively explained by long-distance wind dispersal or by the thriving in situ in unrecognised small wood patches. Twelve ancient woodland indicators (i.e. 36% of a total number found in the region under study) occur exclusively in ancient woodland. It underlines the role of passive species protection in the maintenance of the regional species diversity.

Opis:
The paper contains results of investigations carried out in crop fields within the protected area, which is an important refuge of species diversity in grounds dominated by large-area farms. The segetal vegetation is represented by 13 plant communities, the development of which is influenced by various tillage manipulations. As a result, the segetal flora of the Ślęża Landscape Park is heavily threatened and the structure and species richness of phytocoenoses are distinctly transformed. This is reflected in the frequency of weed occurrence in crops (i.e. there is a small group of common species and a very numerous group of species with 1 or 2 localities), as well as in values of biocoenotic indicators, e.g. the values of diversity indicator H vary between 1 and 3.5. An analysis of archaeophytes participation (frequency and numbers) in ATPOL squares indicates their significant connection with archaeological sites of the Neolithic settlement. Particular adherence to the early Neolithic settlement areas shows a group of species from the Caucalidion alliance. The richness and diversity of the Park vegetation, conditioned by many hundreds of years of agriculture, are now strongly transformed and have become impoverished. Establishing the Landscape Park, in order to preserve the natural-landscape character of the environment and its cultural and historical values, does not ensure the protection of both the species and the phytocoenotic diversity of this area.

Opis:
Croatia is a country of diverse plant use traditions, which are still insufficiently documented. The aim of this study was to document local traditions of using wild food plants around Lake Vrana (northern Dalmatia, Zadar region). We interviewed 43 inhabitants of six traditional villages north of Lake Vrana. On average 12 species were listed, which in total produced an inventory of 55 food plants and 3 fungi taxa. Wild vegetables were most widely collected, particularly by older women who gathered the plants mainly when herding their flocks of sheep. Wild fruits and mushrooms were rarely collected. The former used to be an important supplementary food for children, or for everyone during times of food shortage, and the latter were relatively rare due to the dry climate and shortage of woods. The most commonly collected plants are wild vegetables: Cichorium intybus, Foeniculum vulgare, Sonchus oleraceus, Asparagus acutifolius, Papaver rhoeas, Rumex pulcher, Daucus carota, Allium ampeloprasum and Silene latifolia.

Opis:
In this paper we have analysed invasive flora of Medvednica Nature Park, Croatia with respect to their origins, life forms, systematic positions, types of seed dispersal, Ellenberg indicator values and spatial distributions using MTB 1/64 grid units for analyses. A total of 27 invasive plant species, belonging to 14 families, were recorded with Asteraceae being the most frequently occurring family. Therophytes were the most common life form, as is generally true of Croatian invasive plants; however, hemicryptophytes and geophytes were more frequent in Medvednica. Here, invasive plants originated mainly from both Americas with slightly lower portion in comparison to all Croatian invasive plants, while contrary was the case when comparing those originated from Asia. The most widespread species was Erigeron annuus (L.) Pers., and the species with the lowest occurrence were Chamomilla suaveolens (Pursh.) Rydb and Datura innoxia Mill. A multiple regression model explains 44% of the spatial variability in the invasive plants data per MTB 1/64 unit, using the number of all recorded plant species, the average elevation and the lengths of paths and roads as estimators. The latter two variables also had the most influence on the ordination axes in analyses of the spatial distribution of seed dispersal types present in each MTB 1/64 unit. Anemochory was the most frequent type of seed dispersal.

Opis:
The paper presents the results of several years investigations (2003-2007) on two invaders: the Himalayans Impatiens glandulifera and Asiatic Reynoutria japonica. The Sudety Mountains and their national parks are under strong pressure of both species, threatening the local vegetation. The four-year investigations have been carried out in field, glasshouse and in laboratory. Invasive species have their peculiar life histories which help them to occupy new areas. Those are above all the specific generative reproduction strategies (Impatiens) or vegetative reproduction strategies (Reynoutria). Both strategies secure the reproductive success and to capture more and more highly situated areas of the mountains. Very significant characteristics connected with the expansion of invaders is the excessively over and above the average production of seeds (Impatiens) and a huge annual increment aboveground biomass (Reynoutria). The investigated invasive species are probably not equipped with influence of allelopatic type as of greater importance is their competitive strength. The invaders can eliminate a part of the early spring flora belonging to the geophyte group and impoverish the regional biological diversity. Both the invasive plants enter also into some moist mountain forest communities.

Opis:
The two pondweed taxa, new for the Polish flora, were found in the Drawa River in the Drawieński National Park (north-western Poland). Patches of P. x sparganiifolius started about 400 m below the mouth of the left-bank tributary, the Korytnica River, and ended about 5.5 km further downstream. The population colonized mainly a sandy substrate with varied particle size, moderately deep water, and moderate water flow rate. The patches were very dense and composed nearly exclusively of P. x sparganiifolius. They occurred mainly in the main current of the Drawa, and were up to several dozen metres long. By contrast, P. x nericius was found only in a small creek with stagnant water, at the edge of a patch dominated by P. x sparganiifolius, on a substrate composed of mud and sand, at the depth of 40-60 cm.
