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:
Japanese larch (Larix kaempferi Sarg.) is one of the most frequent exotic species in Polish woodlands. The basic object of research comprised 60 stands of the studied species, located mainly in the northern and western parts of Poland. The growth results for the studied species, evaluated on the basis of the average height (hg55), were compared with data describing the local climate and the stand location within the botanical and climatic zoning. The results confirm the opinion that the Japanese larch prefers a climate of maritime character and generally shows high degree of flexibility regarding its climatic requirements (very large differences between the growth conditions in the studied area and the country of origin). The dependence between the growth results and precipitation is however lower than expected. The most interesting results include the relatively clear connection between the height of the larch stands and the Degórski’s (1984) ‘floristic’ ‘K’ (continentality) index.

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:
Ten species of digeneans were found in a survey of six species of terrestrial birds associated with woodland and urban habitats of north-western Poland carried out in 2006–2009: Leucochloridium paradoxum Carus, 1835 (Leucochloridiidae) from the Cyanistes caeruleus (L.) and the Parus major L. (Paridae); Leuchochloridium perturbatum Pojmańska, 1968 (Leucochloridiidae) from the Turdus merula L., (Turdidae) and the Corvus monedula L. (Corvidae); Leucochloridium sp. (Leucochloridiidae Poche, 1907) from the Asio otus (L.) (Strigidae) and P. major; Strigea strigis (Schrank, 1788) (Strigeidae) from the A. otus; Morishitium elongatum (Harrach, 1921) (Cyclocoelidae) and Psilotornus confertus Machalska, 1974 (Psilostomidae) and Leyogonimus postgonoporos (Neiland, 1951) and Lutztrema attenuatum (Dujardin, 1845) (Dicrocoeliidae) from the T. merula; Plagiorchis maculosus (Rudolphi, 1802) (Plagiorchiidae) from the C. caeruleus; Prosthogonimus ovatus (Rudolphi, 1803) (Prosthogonimidae) from the Dendrocopos major (Linnaeus) (Picidae); Zonorchis petiolatus (Railliet, 1900) (Dicrocoeliidae) from the T. merula and the C. monedula. Five species and one genus of digeneans: L. paradoxum from the C. caeruleus and the P. major; Leucochloridium sp. from the A. otus and P. major; P. confertus from the T. merula; P. maculosus from the C. caeruleus; P. ovatus from the D. major and Z. petiolatus from the C. monedula represent new Polish host records. S. striges and L. postgonoporus represent new Polish locations.

Opis:
Black alder, an N-fixing tree is considered to accelerate the availability of phosphorus in soils due to the increased production of phosphatase enzymes, which are responsible for the P release from the litter. Acid phosphatase activity plays a pivotal role in organic P mineralization in forest soils and in making P available to plants. In order to check whether Alnus glutinosa stimulates acid phosphomonoesterase (PHACID) activity, we compared enzyme activities, total P concentration (PTOT), plant-available P (PAVAIL), organic P (PORG) and inorganic P (PINORG), and organic matter content in 27 ancient and 27 post-agricultural alder woods (the latter ones representing different age classes: 11-20, 21-40 and 41-60 years) of soil samples taken from the litter and the mineral layers. Phosphomonoesterase activity, organic matter, PTOT, PINORG and PORG concentrations were significantly higher in ancient alder woods than in the soils of post-agricultural forests. Significant differences in the acid phosphatase activity, organic matter and PAVAIL concentration were noted between the litter and mineral layers within the same forest type. In recent stands the amount of organic matter and phosphatase activity increased significantly with the age of alder stands, although only in the mineral layer of their soils. Phosphomonoesterase activity, organic matter and PAVAIL content were higher in a litter layer and decreased significantly at a mineral depth of the soil. The acid phosphatase activity was significantly correlated with organic matter content in both ancient and recent stands. There was no significant relationship between PHACID activity and any P forms.
