Antipodal mosses: X. The status of Dichodontium brasiliense and D. opacifolium (Dicranaceae).

Abstract: Two austral moss species, Dichodontium brasiliense Broth. in Schiffn. from south-eastern Brazil and D. opacifolium Dixon in Christ. from Tristan da Cunha, are taxonomically assessed. Both species are briefly characterized and various details of the plants are illustrated. It is shown that they are conspecific with Chrysoblastella chilensis (Mont.) Reim. of the Ditrichaceae. The geographical range of this taxon is reviewed. The relegation of D. brasiliense to Chrysoblastella makes Dichodontium a bitypic genus consisting only of D. pellucidum (Hedw.) Schimp. and D. olympicum Ren. & Card. and having a strictly Holarctic distribution.

Two remarkable hygrophytic mosses new to the bryophyte flora of Yemen (Studies in Arabian bryophytes 25).

Abstract: Two hygrophytic moss species, Bryum pseudotriquetrum (Hedw.) Gaertn., Meyer & Scherb. and Philonotis falcata (Hook.) Mitt., are recorded for the first time from Yemen in the south-western Arabian Peninsula. Both records represent major range extensions of the two species which are briefly described and illustrated on the basis of the local Yemen material. The geographical ranges of both species are briefly assessed and an up-to-date distribution map for Ph. falcata in Asia is presented. The moss flora of Yemen (including Socotra) now totals 94 species.

Abstract: The eutrophic (nutrient rich) fens in the Podhale region (Western Carpathians, Poland) are species rich and well-preserved. Pawłowski et al. (1960) described their vegetation as the Valeriano simplicifoliae-Caricetum flavae association. The author of the current paper presents his own relevés from 1998 and compares all the relevés published from the Podhale region so far. In addition to the traditional Braun-Blanquet approach he uses Principal Components Analysis (PCA) and Twinspan classification. These comparisons suggest that the vegetation of the Podhale spring fens is changing into transitional mire vegetation of the Sphagno warnstorfiani-Tomenthypnion alliance, which is especially characterized by the increase of some slightly acidophilous moss species (Sphagnum warnstorfii, Hypnum pratense, Aulacomnium palustre, Calliergon giganteum and Meesia triquetra) and shallow rooting acidophilous vascular plants (Drosera rotundifolia). Their occurrence is probably dependent upon the acidification of water held in Sphagnum hummocks. The electrical conductivity of the inflowing water and pH values are included. Syntaxonomical relationships between the studied association and the Valeriano simplicifoliae-Caricetum davallianae association and the Sphagno warnstorfiani-Tomenthypnion alliance are discussed.

The genus Najas (Najadaceae) in Poland: remarks on taxonomy, ecology, distribution and conservation.

Abstract: The genus Najas L. is represented by three species in Poland: N. marina L., N. minor All. and N. flexilis (Willd.) Rostk. & Schmidt. N. polonica Zalewski and N. tenuissima (A. Br.) Magn. have also been reported, but their present-day occurrence in Poland has not been confirmed by the author. In this paper the author provides evidence that two subspecies of N. marina thrive in Poland and gives notes on the morphology, ecology of populations and conservation for all Najas spp. extant in Poland. A detailed list of localities based on data from the literature, herbarium material and the author's own observations for these species, is also presented.

New sites for Isoëtes echinospora (Isoëtaceae) in the Pomeranian lakes (NW Poland).

Abstract: Two hitherto unknown sites for Isoëtes echinospora Durieu have been discovered in the Pomeranian Lakeland (NW Poland) in the lakes Jelenie Duże and Jelenie Małe. These form the seventh and eighth known populations of this species in Poland in two of its southernmost localities in the European Lowland. The water of both lakes is acid with low pH, electrical conductivity and calcium content. The more valuable I. echinospora site is in Lake Jelenie Małe where it is very abundant. A significant feature of both lakes is freedom from human interference, which offers some chance of preserving both populations.

Distribution of character species of the Isoëto-Nanojuncetea-class in Poland. Part III. Sagina ciliata, S. subulata, Lythrum hyssopifolia and Mentha pulegium.

Abstract: Distribution maps for Sagina ciliata Fr., S. subulata (Sw.) C. Presl., Lythrum hyssopifolia L. and Mentha pulegium L. in Poland have been prepared on the basis of all accessible data. Brief descriptions of habitats and the general distributions of the species are also given. The taxa are scattered over much of Europe, but in Poland they occur rarely. They reach here the north-eastern limits of their geographical range and are therefore in direct danger of extinction. In Poland they are not satisfactorily documented phytosociologically so there are difficulties in identifying their likely places of their occurrence.

Qualitative and quantitative changes in the moss flora of the Beech Forest nature reserves in NW Poland over the last 30 years.

Abstract: The lists of mosses collected from five Beech Forest nature reserves (Puszcza Bukowa, NW Poland) during the periods 1964-1966 and 1997-1998 were compared. The reserves were only lightly managed so the effects of human impact were not severe. The following changes were noted. (1) The number of species recorded in 1997-1998 showed a 7% increase over the first period. (2) The species composition had changed significantly with the disappearance of 25 taxa (30.1%) and the addition of 31 new ones. (3) Qualitative changes had occurred in the composition of the moss communities - the number of bi- and polysubstrate species had increased and the number of obligatory species had declined. (4) Within particular bryocoenological groups (= synecological types of moss-society; Gams 1932) the changes varied in character. Some (e.g. within the Helophytia and Bryochamaephytia) were fluctuational, that is to say that the overall number of species remained unchanged but the species composition differed. Others were directional - a retreat of epilithic and epiphytic mosses and increases within the Xerogeophytia, Amphiphytia and Epixylia, including facultative epixylics. (5) Human impact had caused obligatory epiphytes to either disappear or adapt to terrestrial-epiphytic sites. “Weedy” species had appeared on the sites of fires and on forest road margins.
The paper also includes a list of all the mosses recorded in the reserves over the 30-year study period.
