Struthiopteris spicant is a medium-sized, dimorphic fern that occurs mainly in Western Europe and Western North America. The species is quite variable, with several forms differing in frond sizes and degree of dimorphism. In addition to the typical plant, in Europe two other varieties are recognized: the Iberian S. s. var. homophyllum includes plan...
Article
The family Blechnaceae is a moderately sized leptosporangiate fern lineage, with 24 genera and around 250 species. Struthiopteris accommodates small to medium‐sized, dimorphic, pinnate species. It is composed of six northern species: S. spicant is distributed in western parts of Europe and North America; S. fallax is endemic to Iceland; S. niponica...

We present a comprehensive list of non-native vascular plants known from the Arctic, explore their geographic distribution, analyze the extent of naturalization and invasion among 23 subregions of the Arctic, and examine pathways of introductions. The presence of 341 non-native taxa in the Arctic was confirmed, of which 188 are naturalized in at le...

The present edition of the annotated checklist is a comprehensive catalogue of all vascular plant taxa: native and alien that occur in Iceland. The checklist features nearly 2500 taxa names, including ca. 1000 accepted names and more than 1400 synonyms and encompasses, apart from the updated list of native taxa, a complete and revised list of non-n...

We report the human-assisted spread of Senecio pseudoarnica, native to the northern coasts of North America and the Far East, to arctic and subarctic regions of Europe. Our fndings indicate that the species, imported as a decorative plant, is currently rapidly spreading along coastal areas of Iceland and Norway. An exponential model comprehensively...

The grass Deschampsia cespitosa is a variable taxon out of which many varieties, subspecies and endemic species have been separated. In this paper, the variation in genome size (GS) and ploidy of this grass including several of its subspecies and two related species in Eurasia was investigated by flow cytometric (FCM) measurements. GS and ploidy da...

This investigation was conducted to identify the content of metals in Calluna vulgaris (family Ericaceae), Empetrum nigrum (family Ericaceae), Festuca vivipara (family Poaceae) and Thymus praecox subsp. arcticus (family Lamiaceae), as well as in the soils where they were growing in eight geothermal heathlands in Iceland. Investigation into the vege...

This paper describes a long-term (1988–2018) data series from pollen monitoring in two locations in Iceland: Akureyri and Reykjavík. Our data showed a low diversity of airborne pollen present in the aeroplankton of Iceland. We showed that Betula spp. and Poaceae can be considered the main pollen allergens in Iceland. Both Betula spp. and Poaceae po...

The process of ecosystem development over time that takes place on a new substrate devoid of biological activity (such as, for example, lava) is called primary succession. Research on primary succession is not easy, as it is limited to rare occasions when a piece of land totally lacking in any pre-existing life occurs. The emergence of volcanic isl...

Background Microsatellite loci, or single sequence repeats (SSR), are widely used as powerful markers in population genetics. They represent an attractive tool for studying plants such as grasses, whose evolution is driven by hybridisation and polyploidization. However, the development of microsatellite markers has been challenging and time-consumi...
Article
Struthiopteris (Blechnaceae) has recently been classified on the basis of molecular and morphological evidence, and some of its species are now included in the sister genus Spicantopsis. However, the lack of studies on several important morphological features impedes a sound assessment of their congruence with this new systematic arrangement, as we...

This review provides a synopsis of the main findings of individual papers in the special issue Terrestrial Biodiversity in a Rapidly Changing Arctic. The special issue was developed to inform the State of the Arctic Terrestrial Biodiversity Report developed by the Circumpolar Biodiversity Monitoring Program (CBMP) of the Conservation of Arctic Flor...

Iceland is an area practically free from pollution but threatened by long-range transported anthropogenic contaminants from mid-and low-latitudes. Therefore the load of trace elements in the environment of this island should be controlled. Accordingly in this investigation we evaluated the level of metals in rocks and soil as well as in two moss sp...
Poster
Full-text available
The poster summarizes the results of the recent study carried out on a pan-Arctic scale and aimed to establish the list of non-native plant species present in the region, their naturalization status and pathways of introduction. Basic taxonomic and biogeographic characteristics of the non-native flora of the Arctic are presented.

The poster summarizes the investigation of the level of metals in two moss species: Sanionia uncinata, Racomitrium lanuginosum. We tested the following hypotheses: 1) S. uncinata and R. lanuginosum may be used as bioindicators of contaminating metals in Iceland, 2) S. uncinata is a better phytoaccumulator of these metals than R. lanuginosum because...

A strongly modified habitat can be treated as “research field”, where microevolutionary processes in plants take place and can be traced. One of such areas are railway tracks. Difficult conditions for plant growth prevail there, including: insolation, water shortage and pollutions. This leads to natural selection, which favors microevolutionary pro...

15 new taxa of non-native vascular plants were recorded in Iceland (during the last five years: 2013-2017). Here, the most important data on first records were described: including exact location, herbarium voucher, collector name and comments summarising some more important details. Each newly recorded species was described in terms of its status...

The Vascular Plant Red List for Iceland reviews the status of plant species according to IUCN red listing guidelines. It was compiled in order to identify species that are threatened with extinction in Iceland and thus facilitate conservation efforts that should be undertaken to improve their status and prevent further decline. Of 436 species asses...

The alkaloids huperzine A and huperzine B were originally isolated from the Chinese club moss Huperzia serrata. They are known inhibitors of acetylcholinesterase, and especially huperzine A shows pharmaceutical potential for the treatment of Alzheimerʼs disease. Its supply heavily relies on natural plant sources belonging to the genus Huperzia, whi...

This article presents for the first time a list of the possible archaeophytes from Iceland. In the present study, all the flowering plant taxa that are considered native/long established in Iceland were assessed against criteria designed to recognize possible archaeophytes. The assessment resulted in a list of 39 taxa meeting (or possibly meeting)...

In 2016, a single, large population of Melampyrum pratense (Orobanchaceae) was discovered in Vaglaskógur forest in NE Iceland. This population can be considered as extremely disjunct as the closest population of this myrmecochorous, slowly dispersing, hemiparasitic plant species is known from the Shetland Islands located ca. 1000 km south-east from...

Plant ecosystem engineers are widely used to combat land degradation. However, the ability of those plants to modulate limiting abiotic and biotic resources of other species can cause damage to ecosystems in which they become invasive. Here, we use Lupinus nootkatensis as example to estimate and project the hazardous potential of nitrogen fixing he...

Delimitation of genera in Blechnaceae Newman (1844: 8), a subcosmopolitan fern family with ca. 250 species, has remained uncertain for a long time. During the last decade, evidence has been accumulating about the polyphyletism within Blechnum Linnaeus (1753: 1077) (e.g. Shepherd et al. 2007, Rothfels et al. 2012, Gabriel y Galán et al. 2013, Perrie...

Blechnum spicant var. fallax Lange is a fern taxon endemic to Iceland where it occurs in the vicinity of hot springs on geothermally heated soils. The taxon was first described by a Danish botanist Johan Martin Christian Lange in 1880 on the basis of plant material collected by Christian Grønlund in Iceland. Because its holotype was not designated...

Research carried out in 2015 showed that at least two taxa from Heracleum genus present in Akureyri (N Iceland) can be found in natural environment outside cultivation: H. mantegazzianum and H. persicum. Both species are well known to be highly invasive in other parts of Europe. Both pose serious risk to human health due to high content of furanocu...
