Areskoug, V. & Thor, G. 2005: Distribution, status and ecology of the lichen Cyphelium notarisii in Sweden. — Ann. Bot. Fennici 42: 317–326.

An inventory of the two largest Swedish occurrences of the lichen Cyphelium notarisii, situated on Visingsö in Småland and at Kovik on Gotland, respectively, was conducted. A third occurrence on Fårö, Gotland was discovered. A total of 21 localities were visited. Only cultural substrates such as wooden barn walls, fishing sheds and gates were utilised by fertile specimens. The species is mostly found on south- to southwest-facing walls with no shade cover, close to a water-body. The current distribution is greatly reduced compared to the historical range of the species. The major current occurrences are characterised by a high concentration of old wooden structures, which strongly indicates that measures to ensure the viability of the species should be taken at the landscape level, rather than on individual localities. Cyphelium notarisii is reported as new to Estonia and Kazakhstan, and C. tigillare is reported as new to Gotland, Sweden.

Jakobsson, A. & Eriksson, O. 2005: Regional distribution and local abundance in the grassland plant Carlina vulgaris in two landscapes in Sweden. — Ann. Bot. Fennici 42: 327–334.

Despite a considerable research interest in relationships between abundance and distribution across species not so many studies have examined this relationship within species. We investigated the relationship between regional distribution and local abundance in the grassland plant Carlina vulgaris (Asteraceae) within and between two regions in southern Sweden. In contrast to what is usually hypothesised, no positive relationship was found between the distribution and abundance of C. vulgaris within the regions, and between regions there was a negative relationship between large-scale distribution and local abundance. A seed-sowing and transplantation experiment suggested that there is no difference in the amount of suitable but unoccupied habitats between the regions, and unoccupied sites were more favourable than occupied sites. The mechanism behind the observed abundance distribution pattern in C. vulgaris could be either a time-lag in population change response, or a negative correlation in resources between the regions.

Kotiranta, H. & Saarenoksa, R. 2005: The genus Athelopsis (Aphyllophorales, Corticiaceae) in Finland. — Ann. Bot. Fennici 42: 335–342.

The genus Athelopsis in Finland consists of three species, viz. A. glaucina (Bourdot & Galzin) Oberw. ex Parmasto, A. lembospora (Bourdot) Oberw. and A. subinconspicua (Litsch.) Jülich. The distribution and habitats are described and the possible relation to the genus Repetobasidium is briefly discussed. The micro-morphology of each species is described and illustrated, as well as the formation of spore pairs and tetrads. A few reference specimens from Italy, Norway and Russia were studied.

Pavlů, V., Hejcman, M., Pavlů, L., Gaisler, J., Nežerková, P. & Guerovich Andaluz, M. 2005: Vegetation changes after cessation of grazing management in the Jizerské Mountains (Czech Republic). — Ann. Bot. Fennici 42: 343–349.

Vegetation changes following the cessation of grazing of highly productive pasture in the Jizerské Mountains in 1997 were studied. The experiment included three replicate pairs of plots and data were collected before and after grazing was ended. Cover was estimated in 1-m² permanent plots. Abandonment of the pasture resulted in a significant decrease in plant species diversity. Annuals and perennials such as Trifolium repens and Poa trivialis disappeared within three years of the end of grazing. Species scores on the first ordination axis of RDA analyses, where time was the only explanatory variable were highly positively correlated with species heights obtained from the local flora and species height was the single parameter that best explained the reaction of species to the cessation of grazing. Within five years of abandonment, differences among swards caused by continuous stocking and rotational grazing had disappeared and tall grasses and shade-tolerant forbs dominated all swards. No new species were recorded after the abandonment of the pasture. If the abandoned grasslands will not reforest, alternative management regimes must be practiced in order to prevent their degradation and spread of tall dominants.

Svensson, M., Johansson, P. & Thor, G. 2005: Lichens of wooden barns and Pinus sylvestris snags in Dalarna, Sweden. — Ann. Bot. Fennici 42: 351–363.

In Sweden, old wooden barns often host a diverse and threatened lichen flora including eight red-listed species, but this kind of barn has declined over the past 100 years. The barns have traditionally been made out of Pinus sylvestris, and it could be hypothesized that pine snags are the natural habitat for many lichens occurring on anthropogenic wood. We compared the lichen flora on old wooden barns in the village of Gärdsjö, Dalarna with that on snags of P. sylvestris. At a level, both species richness and lichen abundance were highest on snags, and for both substrates the north aspects had more species and higher abundance than E, S and W aspects. Overall species richness was similar on the substrates, with a slight tendency for higher g-level diversity on barns. NMS ordination showed clear compositional differences between barns and snags, and also indicated a more heterogeneous vegetation on barns. Implications for conservation measures are discussed.

Wei, X., Wei, J.-Q., Cao, H.-L., Li, F. & Ye, W.-H. 2005: Genetic diversity and differentiation of Camellia euphlebia (Theaceae) in Guangxi, China. — Ann. Bot. Fennici 42: 365–370.

Camellia euphlebia is rare and endangered in China, distributed in a small region in Guangxi province. We studied the level and pattern of the genetic diversity of 84 individuals from four natural C. euphlebia populations by inter-simple sequence repeat (ISSR) markers. Our results indicate a relatively low level of genetic diversity in C. euphlebia at the species level (polymorphic loci = 55.38%, H_T = 0.1537 and H_SP = 0.24) and at the population level (polymorphic loci = 24.23%, H_E = 0.11), and a relatively high degree of differentiation among populations (G_ST = 0.3147, Shannon's index analysis = 37.5%, AMOVA analysis = 35.88%). Gene flow among populations was 0.5443. Inbreeding and limited gene flow might be the key factors resulting in the observed genetic structure of C. euphlebia. Strategies are proposed for the genetic conservation and management of the species.

Aparicio, A. 2005: Limonium silvestrei (Plumbaginaceae), a new agamospecies from southern Spain. — Ann. Bot. Fennici 42: 371–377.

Limonium silvestrei Aparicio (Plumbaginaceae) is described and illustrated from the only known population located within an agricultural landscape in southern Spain. Based in the single A pollen/Cob stigma combination, male sterility, jumbled 3x karyotype and high seed set and germination, L. silvestrei should be regarded as a new agamospecies in Limonium. The number of long metacentric chromosomes observed in the karyotype of this species is in conflict with Erben's theory about the evolution in the genus. The discovery and characterisation of this species stresses the relevance of forest fragments of natural vegetation in agricultural landscapes as biodiversity reservoirs.
