Duran, A. & Menemen, Y. 2002: Linaria dumanii (Scrophulariaceae), a new species from south Anatolia, Turkey. — Ann. Bot. Fennici 38: 85–87.
Linaria dumanii A. Duran & Y. Menemen sp. nova is described from the Akseki district in Turkey. It belongs to the section Pelisserianae Valdés and is related to L. pelisseriana (L.) Miller, from which it mainly differs in its very small flowers.
Hamzaoglu, E. & Kurt, L. 2002: Astragalus duranii (Fabaceae), a new species from Central Anatolia, Turkey. — Ann. Bot. Fennici 38: 89–91.
Astragalus duranii E. Hamzaoglu & L. Kurt sp. nova (Fabaceae) is described from Central Anatolia (Yozgat) in Turkey. It belongs in the section Proselius Bunge and is related to A. czorochensis Charadze, from which it mainly differs in its very long legumes.
Oksanen, I., Lohtander, K., Paulsrud, P. & Rikkinen, J. 2002: A molecular approach to cyanobacterial diversity in a rock-pool community involving gelatinous lichens and free-living Nostoc colonies. — Ann. Bot. Fennici 38: 93–99.
The cyanobacterial symbionts of Collema multipartitum and free-living Nostoc strains were studied by using the nucleotide sequence of the cyanobacterial tRNALeu(UAA) intron as a genetic marker. Biological specimens were collected from a series of interconnected depressions on a limestone pavement in western Ireland. In this material, free-living and lichenised Nostoc strains could be distinguished on the basis of the first variable region of the tRNALeu(UAA) intron. All the variable stem-loops had a similar heptanucleotide repeat motif, but lichenised and free-living strains differed in the number of repeats and in the presence/absence of additional sequences interrupting a single repeat. The results indicate that some filamentous cyanobacteria in rock-pool communities can be rapidly identified by using this molecular marker. The method could prove useful in ecological and environmental studies.
Piippo, S., He, X.-L., Juslén, A., Tan, B. C., Murphy, D. H. & Pócs, T. 2002: Hepatic and hornwort flora of Singapore. — Ann. Bot. Fennici 39: 101–127.
The primary aim of this study was to investigate and document the hepatic and hornwort floras of Singapore. The secondary aim was to compare and understand the changes in the species composition through time in a highly urbanized island environment like Singapore. As presented, a total of 74 species in 37 genera of Hepaticae and Anthocerotae are known from Singapore. Aneura, Cololejeunea, Cyathodium, Folioceros, Harpalejeunea, and Notothylas are new generic records. Thirty-eight species are reported as new for Singapore. Identification keys to the genera and species of Singapore hepatic and hornwort floras are provided. Short descriptions are provided for each species. Of the 74 species, 21 are regarded as possibly extinct from the island on the basis of no recent collections. An additional 16 records could not be confirmed due to lack of voucher specimens and recent collections. Taxa suffered most from the urbanization of environment seem to be those of the genera Bazzania and Frullania. A moderate 40% extinction rate over a period of two centuries was calculated for the liverwort and hornwort floras of Singapore. Their local disappearance is probably caused by forest clearing and the subsequent change of air humidity and, in the case of corticolous species, most probably due to the increased air pollution.
Schill, D. & Long, D. 2002: Anastrophyllum lignicola (Lophoziaceae), a new species from the Sino-Himalaya, and A. hellerianum new to China. — Ann. Bot. Fennici 39: 129–132.
Anastrophyllum lignicola Schill & D.G.Long is described as a new species from Bhutan and China (Yunnan Province). It is closely related to A. hellerianum (Nees) R.M.Schust. but differs primarily in its gemmae which are mostly regularly ellipsoid and 2-celled. The occurrence of A. hellerianum in Bhutan is confirmed and it is reported as new to China, also from Yunnan. Both species are typically found in temperate coniferous forests where they colonize decaying logs.
Suda, J. 2002: New DNA ploidy level in Empetrum (Empetraceae) revealed by flow cytometry. — Ann. Bot. Fennici 39: 133–141.
Ploidy levels of 71 specimens of Empetrum sampled at 32 localities in Sweden, Norway and Denmark were determined by flow cytometry. Diploid E. nigrum was found at ten localities mostly in the southern parts of the area. Tetraploid E. hermaphroditum was recorded from 24 localities between 61deg.30'N and 68deg.30'N. The diploids and the tetraploids co-occurred in three areas in Sweden and Norway; mixed populations were found in Dovrefjel National Park. A new DNA ploidy level, triploids of probably hybrid origin, was discovered in Jotunsheimen NP in Norway. 2C values were 1.29 pg, 1.94 pg and 2.56 pg for the 2x, 3x and 4x levels, respectively, and no reliable evidence for DNA content variation within a given ploidy level was found. These data represent the first estimations of nuclear DNA content in the family Empetraceae.
Taulavuori, K., Laine, K. & Taulavuori, E. 2002: Artificial deacclimation response of Vaccinium myrtillus in mid-winter. — Ann. Bot. Fennici 39: 143–147.
Artificial deacclimation was provided for the bilberry (Vaccinium myrtillus) in Oulu, northern Finland (65deg.N) in mid-winter 1995. The aim was to study the susceptibility of the bilberry to deacclimate in constant temperatures elevated just above the realistic levels (+5 and +10 deg.C). Frost resistance (LT50) of the bilberry stem and bud phenology were followed. The results so far indicate that the bilberry is susceptible to complete deacclimation in mid-winter. However, this deacclimation requires unrealistic temperature elevations or unrealistically prolonged periods of scarcely realistic temperatures.
Terzioglu, S. & Coskunçelebi, K. 2002: Tulipa gumusanica (Liliaceae), a new species from Turkey. — Ann. Bot. Fennici 38: 149–151.
Tulipa gumusanica Terzioglu (Liliaceae) is described as a species new to science and illustrated in line drawings. It occurs in the Vilayet Gümüshane region of Turkey. The chief characters of T. gumusanica are pure yellow stamens and anthers and distinctly undulate leaves.
Vural, M. & Dönmez, A. A. 2002: Two new taxa of Silene (Caryophyllaceae) from Turkey. — Ann. Bot. Fennici 39: 153–158.
Silene koycegizensis Dönmez & Vural sp. nova and S. cariensis Boiss. subsp. muglae Vural & Dönmez subsp. nova (sect. Behenantha Othh.) are described from Turkey. Diagnostic characters, description, detailed illustrations and taxonomic comments on the taxa are given. Their relationships with the allied species S. cretica L., S. tenuiflora Guss. and S. cariensis are discussed. Geographic distributions of the new taxa and other related species are shown on maps.
Wahlman, H. & Milberg, P. 2002: Management of semi-natural grassland vegetation: evaluation of a long-term experiment in southern Sweden. — Ann. Bot. Fennici 39: 159–166.
Vascular plants were recorded in a long-term (28-year) experiment on semi-natural grassland vegetation comparing six treatments: continued grazing, mowing every year, mowing every third year, annual spring burning, removal of woody plants, and untreated control. The treatments had created very different vegetation types: the annually mown and grazed plots had the highest species number while the untreated plots had the lowest. The species' ordination scores correlated with Ellenberg indicator values for nutrient status and light: species indicating poor nutrient conditions were mainly in grazed and mown plots, and shade-tolerant species were mainly in untreated and grazed plots. The original aim of this experiment was to evaluate alternative ways of maintaining semi-natural grassland vegetation, but there were no satisfactory long-term alternatives to annual mowing or grazing. An ordination contrasted annual mowing and grazing, ranking species from those associated with mowed plots (e.g. Leucanthemum vulgare, Luzula pilosa, Campanula persicifolia, Ajuga pyramidalis) to those associated with grazed plots (e.g. Ranunculus spp., Geum spp., Vicia sepium).
