Sramkó, G., Gulyás, G. & Molnár V., A. 2011: Convergent evolution in Ophrys kotschyi (Orchidaceae) revisited: a study using nrITS and cpIGS sequences. Ann. Bot. Fennici 48: 97106.
Convergence in the endangered European bee-orchid species Ophrys kotschyi was studied using a molecular phylogenetic approach. We sequenced the nuclear ribosomal internal transcribed spacer (nrITS) and the Rrn5TrnR intron of the chloroplast DNA (cpIGS) to resolve conflicting interpretations of its relationships. Some authors include all morphologically similar Greek taxa in the study species, others believe that similarity results from convergent evolution driven by a shared pollinator. Parsimony-based network building and three approaches of phylogenetic tree reconstruction provided a basic insight into the phylogeny of the studied taxa, revealing that the inclusion of the various Greek taxa in O. kotschyi results in a polyphyletic species. This implies the consideration of the species as a narrow endemic to Cyprus, and corroborates the view that convergent evolution is responsible for apparent morphological similarity. Additionally, nrITS sequencing revealed additive polymorphic sites in the nrITS, which implies significant inter-specific gene flow.
Björnström, T., Hyvärinen, M., Siikamäki, P., Strengell, H., Väre, H. & Tuomi, J. 2011: Demographic variability and population viability of an endemic variety of the Siberian primrose. Ann. Bot. Fennici 48: 107119.
We used matrix population models to analyse spatial and temporal variation in the demography of the Siberian primrose (Primula nutans ssp. finmarchica var. jokelae), an early successional species of seashore meadows in the Gulf of Bothnia. We compared the dynamics of populations in habitats that were partially overgrown by woody shrubs with those in open ones. The major threat to the populations was the invasion of the habitat by woody plants, as population growth was very sensitive to a change in the transition from a sterile rosette to a flowering one and this transition occurred less frequently in overgrown meadows. This transition also had the greatest contribution to the differences in population growth rates between habitats. Although the invasion of shrubs negatively influenced population growth rate, most populations are still expected to persist and only two small populations out of eleven examined populations were expected to disappear within 50 years. However, with proper habitat management the problem of coarse-scale interactions, such as asymmetric competition for light with shrubs, can be substantially alleviated.
Żmihorski, M. 2011: Forest inventory data reveal stand history from 115 years ago. Ann. Bot. Fennici 48: 120128.
The relationship between the present distribution of some vascular plants in managed forests and forest history was investigated in western Poland. A forest inventory report was used as the source of data for plant distribution in the 211 subcompartments of the forest, and archive maps for the stand history assessment. The 'history' of a subcompartment (ancient vs. recent) increases the parsimony of the models, as assessed with AIC, explaining understory plant species occurrence. Occurrences of Vaccinium myrtillus and Pteridium aquilinum appeared to be most reliable predictors of forest history. Among the 110 sub-compartments where the two species were recorded, 103 were covered by ancient forest. The two plant species selected as reliable predictors of ancient forest continuity also appeared to be significant predictors of forest history in the nearby control area. The use of indicator species described in the reports may be an attractive source of knowledge on the ecosystem.
Harmaja, H. 2011: Printzina lagenifera coll. (Trentepohliales, Chlorophyta) epiphyllous in a boreal forest. Ann. Bot. Fennici 48: 129132.
The green alga Printzina (Trentepohlia) lagenifera was found in southern Finland in the sori of the leaves of the indigenous fern Polypodium vulgare. The find is noteworthy because P. lagenifera occurred epiphyllous in a boreal, natural habitat. The subcosmopolitan P. lagenifera is a collective species; it was described from a hothouse in Germany. Two earlier finds from Finland are likewise from hothouses. The present alga is hardly conspecific with these lignicolous hothouse algae that most probably are introductions from the tropics. Another green alga, the common Desmococcus olivaceus (Chaetophorales) is reported to occur in Finland on the upper surfaces of the leaves of Polypodium vulgare.
Draper, I., González-Mancebo, J. M., Werner, O., Patiño, J. & Ros, R. M. 2011: Phylogeographic relationships between the mosses Exsertotheca intermedia from Macaronesian islands and Neckera baetica from southern glacial refugia of the Iberian Peninsula. Ann. Bot. Fennici 48: 133141.
The phylogeographic relationships between the Macaronesian islands and southern glacial refugia of the Iberian Peninsula was studied using molecular markers and two mosses as model species: Exsertotheca intermedia from Macaronesia and the recently described Neckera baetica from the Iberian Peninsula. The new combination Exsertotheca baetica (Guerra) Draper, González-Mancebo, O. Werner, J. PatiƱo & Ros is proposed for the latter. The genus Neckera has recently undergone considerable systematic and taxonomic changes, but our results show that the European species N. cephalonica and N. pumila belong in Neckera s. stricto.
