Czarnecka, J. 2005: Seed dispersal effectiveness in three adjacent plant communities: xerothermic grassland, brushwood and woodland. — Ann. Bot. Fennici 42: 161– 171.

This study investigates the dispersal ability of seeds and fruits of plant species in three adjacent plant communities — xerothermic grassland, brushwood and woodland — through analysis of the soil seed bank and its changes at the borders of the communities. I tested the following null hypothesis: effective seed dispersal leads to negligible differences in the richness and structure of the seed bank among these plant communities. However, considerable differences, both quantitative and qualitative, were observed among the seed banks of the neighbouring plant communities. I noted the highest average density of seeds, 32450 per square metre, within the brushwood, half of that density (14058) in the grassland seed bank, and less than a tenth of that density (2245) in the woodland bank. Most of the seeds remain in the close vicinity of their parent plants. In the analysed arrangement of plant communities, the most effective methods of seed dispersal seem to be myrmecochoria and endozoochoria. Seeds and fruits of the last type of dispersal are the most abundant in the woodland seed bank, where tree crowns host a lot of birds. Very effective dispersal is also exhibited by Betula pendula, an anemochorous pioneer species, and Hypericum perforatum.

Cabezas, F. J., De la Estrella, M., Aedo, C. & Velayos, M. 2005: Marantaceae of Equatorial Guinea. — Ann. Bot. Fennici 42: 173–184.

A checklist of the Marantaceae of Equatorial Guinea, comprising eleven genera and twenty-six species, is presented. The best represented genus is Marantochloa, with eight species. In addition, bibliographic references for Marantaceae from Equatorial Guinea are gathered and checked. Eight species of Marantaceae are vouched for the first time from the country.

Sudnik-Wójcikowska, B. & Galera, H. 2005: Floristic differences in some anthropogenic habitats in Warsaw. — Ann. Bot. Fennici 42: 185–193.

Floristic studies of four different habitats in Warsaw were carried out: two habitats strongly transformed by man (tramlines and the exterior horizontal surfaces of the highest building in the city, the Palace of Culture and Science), and two green areas (cemeteries and botanical gardens). A floristic list, which included only the spontaneous vascular flora, was compiled for each habitat. The aim of the study was to analyse the differences between the floras of the four habitats. The richness and composition of the flora were investigated with respect to the historical-geographical groups of species, the spectrum of life forms, and the mode of plant dispersal. The richness of the flora of cemeteries and botanical gardens reflected the particular land use of those habitats. There was a higher incidence of therophytes in the strongly transformed habitats (tramlines, Palace). A high incidence of tree seedlings (mostly species producing light seeds) and anemochorous species was observed in the flora of the Palace.

Vignolio, O. R., Biel, C., de Herralde, F., Araujo-Alves, J. P. L. & Savé, R. 2005: Use of water-stress tolerant Lotus creticus and Cynodon dactylon in soil revegetation on different slopes in a Mediterranean climate. — Ann. Bot. Fennici 42: 195–205.

The performance of the legume Lotus creticus growing in mixture with the grass Cynodon dactylon was compared with a L. creticus pure stand in field conditions on 0°, 19° and 32° slopes in Barcelona, Spain. Two harvests were carried out, the first in early summer and the second in mid-autumn. From winter to spring, Lotus creticus growing in mixture contributed a greater biomass than the grass. Total shoot biomass of pure stand and mixture differed among slopes. On the same slope shoot biomass in the mixture and pure stands was not significantly different. The vegetation cover of the mixture was approximately 100%, 90% and 86% on the 19°, 0° and 32° slopes, respectively. The vegetation cover in the pure stand on the three former slopes was approximately 100%. During summer the water deficit was important on the 32° slope and L. creticus plants mortality in the mixture and pure stands was recorded. In autumn, legume biomass in mixture was lower than grass. The vegetation cover in the mixture and pure stands was nearly 100% on the 0° and 19° slopes, and 60% on the 32° slope. During the experiment changes in photosynthesis, water use efficiency and water potential in both species were recorded. Lotus creticus plants growing in mixture were not affected in their physiological variables as compared with those in the pure stand. On a same slope, the mixture and pure stands did not differ in total shoot biomass. In mixture the lowest biomass production in one species was compensated by an increase in the other.
