    Germinating seeds or bulbils in 87 of 113 tested Arctic species indicate potential for ex situ seed bank storage

    Polar Biology.

    Arctic plant species are expected to lose range due to climate change. One approach to preserve the genetic and species diversity for the future is to store propagules in seed vaults. However, germinability of seeds is assumed to be low for Arctic species. We evaluated ex situ storage potential of 113 of the 161 native angiosperms of Svalbard by studying seed ripening and germination. Seeds or bulbils were collected, and germinability was tested after one winter of storage in the Svalbard Global Seed Vault. Twenty-six of the species did not produce ripe propagules, 8 produced bulbils, and 79 produced seeds. Bulbils sprouted to high percentages. Seeds of 10 species did not germinate, 22 had low germination (<20 %), 34 had germination of 21–70 %, and 13 had high germination percentages (>70 %). More than 70 % of the species belonging to Asteraceae, Brassicaceae, Caryophyllaceae, Juncaceae, Rosaceae, and Saxifragaceae germinated. Cold tolerant, common species had higher germination percentages than relatively thermophilous, rare species. Germination percentages were six times higher than observed in 1969 (n = 51) and 0.7 times that observed in 2008 (n = 22), indicating that recent climate warming improves germination in the Arctic. While in situ conservation is of vital importance, ex situ conservation in seed banks is a potential complementary conservation strategy for the majority of Arctic vascular plant species. For species that did not germinate, other methods for ex situ conservation should be sought, for example, growing in botanical gardens

    Taxonomy, biogeography and DNA barcodes of Geodia species (Porifera, Demospongiae, Tetractinellida) in the Atlantic boreo-arctic region

    (Journal name unavailable from Mendeley API. To be updated soon...)

    Geodia species north of 60°N in the Atlantic appeared in the literature for the first time when Bowerbank described Geodia barretti and G. macandrewii in 1858 from western Norway. Since then, a number of species have been based on material from various parts of the region: G. simplex, Isops phlegraei, I. pallida, I. sphaeroides, Synops pyriformis, G. parva, G. normani, G. atlantica, Sidonops mesotriaena (now called G. hentscheli), and G. simplicissima. In addition to these 12 nominal species, four species described from elsewhere are claimed to have been identified in material from the northeast Atlantic, namely G. nodastrella and G. cydonium (and its synonyms Cydonium muelleri and Geodia gigas). In this paper, we revise the boreo-arctic Geodia species using morphological, molecular, and biogeographical data. We notably compare northwest and northeast Atlantic specimens. Biological data (reproduction, biochemistry, microbiology, epibionts) for each species are also reviewed. Our results show that there are six valid species of boreo-arctic Atlantic Geodia while other names are synonyms or mis-identifications. Geodia barretti, G. atlantica, G. macandrewii, and G. hentscheli are well established and widely distributed. The same goes for Geodia phlegraei, but this species shows a striking geographical and bathymetric variation, which led us to recognize two species, G. phlegraei and G. parva (here resurrected). Some Geodia are arctic species (G. hentscheli, G. parva), while others are typically boreal (G. atlantica, G. barretti, G. phlegraei, G. macandrewii). No morphological differences were found between specimens from the northeast and northwest Atlantic, except for G. parva. The Folmer cytochrome oxidase subunit I (COI) fragment is unique for every species and invariable over their whole distribution range, except for G. barretti which had two haplotypes. 18S is unique for four species but cannot discriminate G. phlegraei and G. parva. Two keys to the boreo-arctic Geodia are included, one based on external morphology, the other based on spicule morphology.

    Climate change impact on seaweed meadow distribution in the North Atlantic rocky intertidal

    (Journal name unavailable from Mendeley API. To be updated soon...)

    The North-Atlantic has warmed faster than all other ocean basins and climate change scenarios predict sea surface temperature isotherms to shift up to 600 km northwards by the end of the 21st century. The pole-ward shift has already begun for many temperate seaweed species that are important intertidal foundation species. We asked the question: Where will climate change have the greatest impact on three foundational, macroalgal species that occur along North-Atlantic shores: Fucus serratus, Fucus vesiculosus, and Ascophyllum nodo- sum? To predict distributional changes of these key species under three IPCC (Intergovernmental Panel on Climate Change) climate change scenarios (A2, A1B, and B1) over the coming two centuries, we generated Ecological Niche Models with the program MAXENT. Model predictions suggest that these three species will shift northwards as an assemblage or “unit” and that phytogeo- graphic changes will be most pronounced in the southern Arctic and the south- ern temperate provinces. Our models predict that Arctic shores in Canada, Greenland, and Spitsbergen will become suitable for all three species by 2100. Shores south of 45° North will become unsuitable for at least two of the three focal species on both the Northwest- and Northeast-Atlantic coasts by 2200. If these foundational species are unable to adapt to the rising temperatures, they will lose their centers of genetic diversity and their loss will trigger an unpredictable shift in the North-Atlantic intertidal ecosystem.

    Genetic consequences of climate change for northern plants.

    Proceedings. Biological sciences / The Royal Society 279(1735) 2042-51.

    Climate change will lead to loss of range for many species, and thus to loss of genetic diversity crucial for their long-term persistence. We analysed range-wide genetic diversity (amplified fragment length polymorphisms) in 9581 samples from 1200 populations of 27 northern plant species, to assess genetic consequences of range reduction and potential association with species traits. We used species distribution modelling (SDM, eight techniques, two global circulation models and two emission scenarios) to predict loss of range and genetic diversity by 2080. Loss of genetic diversity varied considerably among species, and this variation could be explained by dispersal adaptation (up to 57%) and by genetic differentiation among populations (F(ST); up to 61%). Herbs lacking adaptations for long-distance dispersal were estimated to lose genetic diversity at higher rate than dwarf shrubs adapted to long-distance dispersal. The expected range reduction in these 27 northern species was larger than reported for temperate plants, and all were predicted to lose genetic diversity according to at least one scenario. SDM combined with F(ST) estimates and/or with species trait information thus allows the prediction of species' vulnerability to climate change, aiding rational prioritization of conservation efforts.

    A Battle Lost? Report on Two Centuries of Invasion and Management of Lantana camara L. in Australia, India and South Africa

    PLoS ONE 7(3) e32407.

    Recent discussion on invasive species has invigorated the debate on strategies to manage these species. Lantana camara L., a shrub native to the American tropics, has become one of the worst weeds in recorded history. In Australia, India and South Africa, Lantana has become very widespread occupying millions of hectares of land. Here, we examine historical records to reconstruct invasion and management of Lantana over two centuries and ask: Can we fight the spread of invasive species or do we need to develop strategies for their adaptive management? We carried out extensive research of historical records constituting over 75% of records on invasion and management of this species in the three countries. The records indicate that governments in Australia, India and South Africa have taken aggressive measures to eradicate Lantana over the last two centuries, but these efforts have been largely unsuccessful. We found that despite control measures, the invasion trajectory of Lantana has continued upwards and that post-war land-use change might have been a possible trigger for this spread. A large majority of studies on invasive species address timescales of less than one year; and even fewer address timescales of >10 years. An understanding of species invasions over long time-scales is of paramount importance. While archival records may give only a partial picture of the spread and management of invasive species, in the absence of any other long-term dataset on the ecology of Lantana, our study provides an important insight into its invasion, spread and management over two centuries and across three continents. While the established paradigm is to expend available resources on attempting to eradicate invasive species, our findings suggest that in the future, conservationists will need to develop strategies for their adaptive management rather than fighting a losing battle.

    Selection and inertia in the evolution of holocentric chromosomes in sedges (Carex, Cyperaceae)

    The New phytologist 195(1) 237-47.

    • Changes in chromosome number as a result of fission and fusion in holocentrics have direct and immediate effects on the recombination rate. We investigate the support for the classic hypothesis that environmental stability selects for increased recombination rates. • We employed a phylogenetic and cytogenetic data set from one of the most diverse angiosperm genera in the world, which has the largest nonpolyploid chromosome radiation (Carex, Cyperaceae; 2n = 12-124; 2100 spp.). We evaluated alternative Ornstein-Uhlenbeck models of chromosome number adaptation to the environment in an information-theoretic framework. • We found moderate support for a positive influence of lateral inflorescence unit size on chromosome number, which may be selected in a stable environment in which resources for reproductive investment are larger. We found weak support for a positive influence on chromosome number of water-saturated soils and among-month temperature constancy, which would be expected to be negatively select for pioneering species. Chromosome number showed a strong phylogenetic signal. • We argue that our finding of small but significant effects of life history and ecology is compatible with our original hypothesis regarding selection of optima in recombination rates: low recombination rate is optimal when inmediate fitness is required. By contrast, high recombination rate is optimal when stable environments allow for evolutionary innovation.

    Lacewings (Neuroptera) and Alderflies (Megaloptera) from Finnmark, northern Norway

    (Journal name unavailable from Mendeley API. To be updated soon...)

    Records of 22 species of Neuroptera and four species of Megaloptera from Finnmark, northern Norway are presented based partly on material collected in 2010, partly on material housed in the entomological collections at the Natural History museums in Norway. Of these, 13 species have previously not been recorded from Finnmark, i.e.: Coniopteryx tineiformis Curtis, 1834; Hemerobius atrifrons McLachlan, 1868; H. fenestratus Tjeder, 1932; H. humulinus Linnaeus, 1758; H. marginatus Stephens, 1836; H. nitidulus Fabricius, 1777; H. pini Stephens, 1836; Micromus angulatus (Stephens, 1836); Sympherobius fuscescens (Wallengren, 1863); Wesmaelius concinnus (Stephens, 1836); W. mortoni (McLachlan, 1899); W. quadrifasciatus (Reuter, 1894) and Chrysoperla carnea (Stephens, 1836). The total number of Neuroptera known to occur in Finnmark is now 23 of which four belong in the family Coniopterygidae, 17 in Hemerobidae, and one in each of the families Chrysopidae and Sisyridae. All four species of Megaloptera reported in this paper belong to the genus Sialis Latreille, 1802, the sole genus of the order occurring in Norway. One of these, Sialis sibirica McLachlan, 1872, is recorded as Data Deficient (DD) in the 2010 Norwegian Red List for Species. In addition to the four species reported here a fifth species, Sialis lutaria (Linnaeus, 1758) is known to occur in Finnmark.

    A review of the Ephemeroptera of Finnmark – DNA barcodes identify Holarctic relations

    Norwgian Journal of Entomology 59 182-195.

    The knowledge of the diversity and distribution of mayflies in Finnmark county, the northernmost part of mainland Norway, is reviewed. Eighty five DNA barcodes representing 23 species in the region are released and used in association of life stages as well as evaluation of morphological characters commonly used in identification of Scandinavian Ephemeroptera. Comparisons of DNA barcodes from North American species indicate close relations between Norwegian and North American populations of Acentrella lapponica Bengtsson, 1912, Heptagenia dalecarlica Bengtsson, 1912, Metretopus borealis (Bengtsson, 1909), Ephemerella aurvillii (Bengtsson, 1908) and Parameletus chelifer Bengtsson, 1908. The DNA barcode from Siphlonurus alternatus (Say, 1824) cluster closely with specimens of the same species from Finland, but are more than 7.8% different from North American populations, indicating that the Fennoscandian specimens might constitute a separate species. Two species new to Finnmark and ten new province records are reported.

    Comparative analyses reveal potential uses of Brachypodium distachyon as a model for cold stress responses in temperate grasses.

    (Journal name unavailable from Mendeley API. To be updated soon...)

    BACKGROUND: Little is known about the potential of Brachypodium distachyon as a model for low temperature stress responses in Pooideae. The ice recrystallization inhibition proteins (IRIP) genes, fructosyltransferase (FST) genes, and many C-repeat binding factor (CBF) genes are Pooideae specific and important in low temperature responses. Here we use comparative analyses to study conservation and evolution of these gene families in B. distachyon to better understand B. distachyon's potential as a model species for agriculturally important temperate grasses RESULTS: Brachypodium distachyon contains cold responsive IRIP genes which have evolved through Brachypodium specific gene family expansions. A large cold responsive CBF3 subfamily was identified in B. distachyon, while CBF4 homologs are absent from the genome. No B. distachyon FST gene homologs encode typical core Pooideae FST-motifs and low temperature induced fructan accumulation was dramatically different in B. distachyon compared to core Pooideae species. CONCLUSIONS: We conclude that B. distachyon can serve as an interesting model for specific molecular mechanisms involved in low temperature responses in core Pooideae species. However, the evolutionary history of key genes involved in low temperature responses has been different in Brachypodium and core Pooideae species. These differences limit the use of B. distachyon as a model for holistic studies relevant for agricultural core Pooideae species.

    Modeling alpine plant distributions at the landscape scale: Do biotic interactions matter?

    (Journal name unavailable from Mendeley API. To be updated soon...)

    Species Distribution Models (SDMs) generally ignore biotic processes. However, it has been shown that biotic interactions from lowland flora contribute to shape the “rear edge” of alpine plant distributions. In this study, we explored the potential effect of accounting for interactions from dominant lowland congeners representative for the lowland flora for predicting landscape scale distribution (1 km grain) of two alpine plant species, Viola biflora and Veronica alpina. In a first classical approach, we include the lowland species probabilities of occurrence as covariates in the alpine species landscape scale models (covariate models). In a second novel approach, we first used SDMs to predict the distribution of the two alpine plants at the landscape scale. We then searched for interactive effects with the lowland species, and used this information to re-predict the landscape parts where alpine and lowland species were previously predicted to co-occur (abiotic + biotic models). Our ‘abiotic + biotic’ model improved model precision for both alpine species; but statistically signif- icantly for Viola biflora only. In contrast, the classical covariate approach did not affect the prediction accuracy of Viola biflora and decreased the prediction accuracy for Veronica alpina. This seemed to be caused by collinearity between abiotic and biotic predictors, highlighting potential problems with the conventional method used to account for biotic interactions in SDM. Including potential effects of biotic interactions can improve predictions of alpine species’ ranges at the landscape scale. Ignoring biotic interactions in SDM may lead to biased predictions that are likely to overestimate realized climatic niches and so species distributions. The abiotic + biotic approach can constitute a robust method to account for biotic interactions in SDM.
