    Patterns of diversification amongst tropical regions compared: a case study in Sapotaceae.2014In: Frontiers in Genetics, ISSN 1664-8021, E-ISSN 1664-8021, Vol. 5, no 362Article in journal (Refereed)
    Abstract [en]

    Species diversity is unequally distributed across the globe,with the greatest concentration occurring in the tropics. Even within the tropics, there are significant differences in the numbers of taxa found in each continental region. Manilkara is a pantropical genus of trees in the Sapotaceae comprising c.78 species. Its distribution allows for biogeographic investigation and testing of whether rates of diversification differ amongst tropical regions. The age and geographical origin of Manilkara are inferred to determine whether Gondwanan break-up, boreotropical migration or long distance dispersal have shaped its current disjunct distribution. Diversification rates through time are also analyzed to determine whether the timing and tempo of speciation on each continent coincides with geoclimatic events. Bayesian analyses of nuclear (ITS) and plastid (rpl32-trnL,rps16-trnK,and trnS-trnFM) sequences were used to reconstruct a species level phylogeny of Manilkara and related genera in the tribe Mimusopeae. Analyses of the nuclear data using a fossil-calibrated relaxed molecular clock indicate that Manilkara evolved 32–29 million years ago (Mya) in Africa. Lineages within the genus dispersed to the Neotropics 26–18 Mya and to Asia 28–15 Mya. Higher speciation rates are found in the Neotropical Manilkara clade than in either African or Asian clades. Dating of regional diversification correlates with known palaeoclimatic events. In South America, the divergence between Atlantic coastal forest and Amazonian clades coincides with the formation of drier Cerrado and Caatinga habitats between them. In Africa diversification coincides with Tertiary cycles of aridification an duplif tof the east African plateaux. In South east Asia dispersal may have been limited by the relatively recent emergence of land in New Guinea and islands further east c.10 Mya.

    Abstract [en]

    A small part of the Gobholo cave in westernSwaziland (southern Africa) has been usedfor touristic adventure tours for a few years,but the cave has never been surveyed norinvestigated scientifically. An internationalteam of speleologists started exploring, surveyingand documenting the cave in early2014. So far, more than 1 km has been surveyed,making Gobholo cave one of theworld’s longest granite caves and severalcontinuations are still unexplored. The upperparts of the cave are located in a rockfalldeposit overlying the Gobholo river, whereasthe lower parts originated from in-situweathering of the archaic alkali feldspargranite. The river floods large parts of thecave during heavy rainfalls and is responsiblefor the partial removal of the weatheringmaterial out of the cave. Manifold and numerousflowstones (composed of opal-Aand pigotite) probably formed via microbialprocesses. The cave is also a habitat for variousanimal species, including bats, spidersand cave crickets. Archaeologic artefactsprobably dating back to the local Stone Ageand Iron Age bear evidence of a former culturaluse of the cave. A thermal spring wasfound and temperature, CO2 and radonmeasurements provide data about the caveclimate which is characterised by fairly goodventilation. The age of the cave is uncertainbut the only approximately dated archaeologicalartefacts suggest a minimum age of40,000 years.

    Estimating the Phanerozoic history of the Ascomycota lineages: Combining fossil and molecular data2014In: Molecular Phylogenetics and Evolution, ISSN 1055-7903, E-ISSN 1095-9513, no 78, p. 386-398Article in journal (Refereed)
    Abstract [en]

    The phylum Ascomycota is by far the largest group in the fungal kingdom. Ecologically important mutualisticassociations such as mycorrhizae and lichens have evolved in this group, which are regarded as keyinnovations that supported the evolution of land plants. Only a few attempts have been made to date theorigin of Ascomycota lineages by using molecular clock methods, which is primarily due to the lack ofsatisfactory fossil calibration data. For this reason we have evaluated all of the oldest available ascomycetefossils from amber (Albian to Miocene) and chert (Devonian and Maastrichtian). The fossils representfive major ascomycete classes (Coniocybomycetes, Dothideomycetes, Eurotiomycetes, Laboulbeniomycetes,and Lecanoromycetes). We have assembled a multi-gene data set (18SrDNA, 28SrDNA, RPB1 andRPB2) from a total of 145 taxa representing most groups of the Ascomycota and utilized fossil calibrationpoints solely from within the ascomycetes to estimate divergence times of Ascomycota lineages with aBayesian approach. Our results suggest an initial diversification of the Pezizomycotina in the Ordovician,followed by repeated splits of lineages throughout the Phanerozoic, and indicate that this continuousdiversification was unaffected by mass extinctions. We suggest that the ecological diversity within eachlineage ensured that at least some taxa of each group were able to survive global crises and rapidlyrecovered.

    Phylogeny of the Athroismeae (Asteraceae), with a new circumscription of the tribe2017In: Taxon, ISSN 0040-0262, E-ISSN 1996-8175, Vol. 66, no 2, p. 408-420Article in journal (Refereed)
    Abstract [en]

    Athroismeae is a small tribe of the Asteraceae-Asteroideae, the members of which show considerable variation in morphology. A molecular phylogenetic study of the tribe is presented for the first time, based on plastid (ndhF, trnH-psbA, trnL-trnF) and nuclear data (ETS, ITS). The phylogenetic relationships between the different genera within Athroismeae are discussed, and in addition, three unispecific genera: Anisochaeta, Artemisiopsis and Symphyllocarpus as well as Duhaldea (Inula) stuhlmannii, all earlier placed in other tribes, are here shown to belong within Athroismeae. Symphyllocarpus is sister to Centipeda and the earlier Symphyllocarpinae includes Centipedinae in synonymy. Furthermore, Cardosoa and Philyrophyllum are found to be integrated within Anisopappus and their generic status cannot be maintained. An outline of an amended circumscription of the Athroismeae is presented, with three new combinations and a description of the new subtribe Lowryanthinae.

    Evolution and diversification related to rainfall regimes: diversification patterns in the South African genus Metalasia (Asteraceae-Gnaphalieae).2015In: Journal of Biogeography, ISSN 0305-0270, E-ISSN 1365-2699, Vol. 42, no 1, p. 121-131Article in journal (Refereed)
    Abstract [en]

    Aim. The Cape region is known for its exceptional species richness, although much remains unknown regarding the appearance of the modern Cape flora. One explanation is that floral diversification was influenced by the establishment of winter rainfall/summer arid conditions hypothesized to have occurred towards the end of the Miocene. We studied the evolution and diversification of the plant genus Metalasia (Asteraceae–Gnaphalieae), with the aim of testing whether radiation patterns may have been influenced by the climatic changes.

    Location. South Africa, with emphasis on the south-west.

    Methods. The radiation of Metalasia was investigated using two approaches: a species diffusion approach, which estimated the ancestral areas by means of a relaxed random walk while sampling from extant distributions; and a discrete approach, in which distributions were defined according to the phytogeographical centres of the Cape region. Secondarily derived clock rates from an earlier Gnaphalieae study were used for calibration purposes.

    Results. Our analyses date Metalasia to approximately 6.9 Ma, after the Miocene–Pliocene boundary and the establishment of the winter rainfall/summer arid conditions. Metalasia consists of two sister clades: Clade A and Clade B. Clade B, which is endemic to the winter rainfall area, is estimated to have diversified c. 6.4 Ma, whereas Clade A, with a main distribution in the all-year rainfall area, is considerably younger, with a crown group age estimated to 3.3 Ma. Diversification rates suggest an early rapid speciation, with rates decreasing through time both for Metalasia and for clades A and B separately. Ancestral area estimations show a possible scenario for the radiation of Metalasia to its current diversity and distribution, with no conflict between results inferred from diffusion or discrete methods.

    Main conclusions. The diversification of Metalasia is estimated to have begun after the establishment of the winter rainfall/summer arid conditions, consistent with its radiation having been influenced by changes in the climatic regime.

    No evidence of sexual niche partitioning in a dioecious moss with raresexual reproduction2015In: Annals of Botany, ISSN 0305-7364, E-ISSN 1095-8290Article in journal (Refereed)
    Abstract [en]

    Background and Aims. Roughly half of the species of bryophytes have separate sexes (dioecious) and half are hermaphroditic (monoecious). This variation has major consequences for the ecology and evolution of the different species. In some sexually reproducing dioecious bryophytes, sex ratio has been shown to vary with environmental conditions. This study focuses on the dioecious wetland moss Drepanocladus trifarius, which rarely produces sexual branches or sporophytes and lacks apparent secondary sex characteristics, and examines whether genetic sexes exhibit different habitat preferences, i.e. whether sexual niche partitioning occurs.

    Methods. A total of 277 shoots of D. trifarius were randomly sampled at 214 locations and 12 environmental factors were quantified at each site. Sex was assigned to the individual shoots collected in the natural environments, regardless of their reproductive status, using a specifically designed molecular marker associated with female sex.

    Key Results. Male and female shoots did not differ in shoot biomass, the sexes were randomly distributed with respect to each other, and environmental conditions at male and female sampling locations did not differ. Collectively, this demonstrates a lack of sexual niche segregation. Adult genetic sex ratio was female-biased, with 28 females for every male individual.

    Conclusions. The results show that although the sexes of D. trifarius did not differ with regard to annual growth, spatial distribution or habitat requirements, the genetic sex ratio as nevertheless significantly female-biased. This supports the notion that factors other than sex-related differences in reproductive costs and sexual dimorphism can also drive the evolution of biased sex ratios in plants

    Family affiliation, sexratio and sporophyte frequency in unisexual mosses2014In: Botanical journal of the Linnean Society, ISSN 0024-4074, E-ISSN 1095-8339, Vol. 174, p. 163-172Article in journal (Refereed)
    Abstract [en]

    Patterns of sex expression and sex ratios are key features of the life histories of organisms. Bryophytes are the only haploid-dominant land plants. In contrast with seed plants, more than half of bryophyte species are dioecious, with rare sexual expression and sporophyte formation and a commonly female-biased sex ratio. We asked whether variation in sex expression, sex ratio and sporophyte frequency in ten dioecious pleurocarpous wetland mosses of two different families was best explained by assuming that character states  evolved: (1) in ancestors within the respective families or (2) at the species level as a response to recent habitat conditions. Lasso regression shrinkage identified relationships between family membership and sex ratio and sporophyte frequency, whereas environmental conditions were not correlated with any investigated reproductive trait. Sex ratio and sporophyte frequency were correlated with each other. Our results suggest that ancestry is more important than the current environment in explaining reproductive patterns at and above the species level in the studied wetland mosses, and that mechanisms controlling sex ratio and sporophyte frequency are phylogenetically conserved. Obviously, ancestry should be considered in the study of reproductive character state variation in plants.

    Infraspecific sex ratio variation and its predictors in mosses – the case of the wetland moss Drepanocladus lycopodioides2015In: Botany 2015. Science and Plants for People. Abstracts. / [ed] Anonymous, 2015Conference paper (Other academic)
    Abstract [en]

    Sex ratio variation is a common but unexplained phenomenon of many species with chromosomal sex determination, including many bryophytes. Expressed sex ratio variation could be related to environmental conditions in a few mosses investigated to date. However, many bryophyte populations are non-fertile during their entire life cycle and intraspecific genetic sex ratio variation remains highly unexplored in natural populations. Drepanocladus lycopodioides, a pleurocarpous wetland moss with a distribution largely confined to Western Eurasia, rarely to occasionally forms sexual organs. It belongs to the majority of bryophytes that exhibits a female bias in expressed sex ratio. We applied a novel approach to sex individual shoots irrespective of their reproductive state using a specifically designed female-targeting molecular marker. We demonstrated that the bias in sex expression corresponds to a genetic female bias in the European adult population. Here, we investigated three regional populations of D. lycopodioides in its core distribution area. We asked whether haplotype diversity (H), sex expression (SE), genetic sex ratios, and sporophyte frequency varied within and among regions, whether these characteristics were related with each other, and / or to environmental parameters. Levels of H differed among regions and were positively related to habitat patch size. H was unequally partitioned between the sexes and was associated with estimated regional sporophyte frequency. Recorded plot-wise sporophyte frequency was generally very low in all regions. Overall genetic sex ratio was female-biased in all regions. Sex expression and genetic sex ratio varied strongly within regions (SE 0 –75%), with 27% of the plots lacking sex organs and 78% of the plots one-sexed, but differences among regions were non-significant. While no sex expression occurred in habitats deeper than 25cm, genetic sex ratio was not related to the measured environmental parameters.

    Males Are Not Shy in the Wetland Moss Drepanocladus lycopodioides2013In: International journal of plant sciences, ISSN 1058-5893, E-ISSN 1537-5315, Vol. 174, no 5, p. 733-739Article in journal (Refereed)
    Abstract [en]

    Premise of research. Maintenance of dioecious and monoecious sexual systems at nearly equal frequencies, infrequent sexual expression, and distinctly female-skewed sex ratios among the dioecious species are reproductive characteristics of bryophytes, which are otherwise unusual among embryophytes. Most sex ratio assessments to date have relied on gametophytes forming sexual organs, and how these reflect genetic genders is largely unresolved.

    Methodology. For the European wetland moss Drepanocladus lycopodioides, we ask whether the adult expressed sex ratio is more strongly female biased than the “true” population sex ratio based on genetically male and female plants, i.e., whether males exhibit a lower sex expression rate than females (shy males). We assess expressed sex ratio on the basis of sex expression in individually scored herbarium specimens. We directly and on a large geographic scale assess nonexpressed sex ratio, for the second time in a moss, by sexing individual shoots from nonexpressing specimens using a molecular sex marker.

    Pivotal results. On the basis of the female and male frequencies in these two data sets and the overall proportion of expressing specimens, we estimate the European population sex ratio as 2.6 : 1 (female to male). All three sex ratios are significantly female skewed and do not significantly differ from each other, indicating that there is no gender difference in sex expression rates.

    Conclusions. These results and previous data for Drepanocladus trifarius show that males are not shy in the two wetland mosses of markedly different habitats.

    Mass occurrence of springtails on a moss cushion – what are they doing?2015In: Melting Pot, Swedish Museum of Natural History, Abstracts: https://vega.nrm.se/vanstermenyn/forskningochsamlingar/meltingpot/2015.9654.html, 2015Conference paper (Other academic)
    Abstract [en]

    The motile spermatozoids of bryophytes can swim up to a few centimetres. They require free water to fertilize the egg of the female organs, which sit on plants separate from the males in more than 50% of the species. When the sex organs are produced on different plants, this presents a serious obstacle to successful fertilization. The problems are overcome by a variety of mechanisms. Some of the more spectacular include spermatozoid transport up to at least several decimetres by water movement, by water drops spread from splash-cups surrounding the male organs up to two meters, by ejection up to15 centimetres into the air, or by having dwarf males that grow directly on the female plants. Here we report on another special kind of spermatozoid transfer that we came across during fieldwork in 2014, namely by micro-arthropods. Bryophyte fertilization mediated by animals was suggested more than a century ago, and was recently shown to occur in experimental settings. However, our observation is likely one of the first made directly in nature.

    786 svampar på 2015 års rödlista2015In: Svensk Mykologisk Tidskrift, ISSN 1653-0357, Vol. 36, p. 91-97-Article in journal (Other (popular science, discussion, etc.))
    Abstract [en]

    A new Swedish Red List was published April 28th 2015 by the Swedish Species Information Centre in which 786 species of fungi are listed. Compared to the previous Red List published in 2010, 11 species have been down-listed, 51 species have been added and 35 species have changed names or taxonomic rank, thus the list has increased by 41. The changes are mainly due to increased knowledge of taxonomy, ecology and distribution, not to changes in the sta-tus of the species. Here, the members of the Species Specialist Group for Fungi 2011 – 2015 summarize the results of the red listing.

    Towards a natural classification of Sapotaceae subfamily Chrysophylloideae in the Neotropics2017In: Botanical journal of the Linnean Society, ISSN 0024-4074, E-ISSN 1095-8339, Vol. 185, p. 27-55Article in journal (Refereed)
    Abstract [en]

    Generic limits of Chrysophyllum and Pouteria (Chrysophylloideae, Sapotaceae) have been found to be untenable. We here search for natural lineages in Neotropical Chrysophylloideae by sampling 101 terminals for molecular sequences of nuclear ribosomal DNA (external and internal transcribed spacer), the nuclear gene RPB2 and 17 morphological characters. Data were analysed with Bayesian inference and parsimony jackknifing. Morphological traits were finally optimized onto the tree to identify the most coherent characters. The resulting phylogenetic tree suggests that the limits of the well-known genera Chrysophyllum and Pouteria must be amended. Diploon, Ecclinusa and Elaeoluma can be maintained and Chrysophyllum sections Ragala section Prieurella and the satellite gen- era Achrouteria, Cornuella, Martiusella and Nemaluma merit generic resurrection. Lucuma may be restored if the type species belongs to the clade. The accepted genera Chromolucuma, Pradosia and Sarcaulus gain strong clade support, but are embedded in a core clade of Pouteria and may be relegated to the subgeneric level if morphologi- cal studies cannot provide evidence concurring with narrow generic concepts. Circumscriptions of Micropholis and Chrysophyllum sections Chrysophyllum and Villocuspis remain unclear and must be explored by using an extended taxon sampling. We predict that yet-to-be-analysed species of Pouteria sections Franchetella, Gayella, Oxythece and Pouteria and members of the currently accepted genera Chromolucuma, Pradosia and Sarcaulus will fall inside the core clade of Pouteria when analysed.

    Phylogenetic Properties of 50 Nuclear Loci in Medicago (Leguminosae) Generated Using Multiplexed Sequence Capture and Next-Generation Sequencing2014In: PLoS ONE, ISSN 1932-6203, E-ISSN 1932-6203, Vol. 9, no 10Article in journal (Refereed)
    Abstract [en]

    Next-generation sequencing technology has increased the capacity to generate molecular data for plant biological research,including phylogenetics, and can potentially contribute to resolving complex phylogenetic problems. The evolutionaryhistory of Medicago L. (Leguminosae: Trifoliae) remains unresolved due to incongruence between published phylogenies.Identification of the processes causing this genealogical incongruence is essential for the inference of a correct speciesphylogeny of the genus and requires that more molecular data, preferably from low-copy nuclear genes, are obtainedacross different species. Here we report the development of 50 novel LCN markers in Medicago and assess the phylogeneticproperties of each marker. We used the genomic resources available for Medicago truncatula Gaertn., hybridisation-basedgene enrichment (sequence capture) techniques and Next-Generation Sequencing to generate sequences. This alternativeproves to be a cost-effective approach to amplicon sequencing in phylogenetic studies at the genus or tribe level andallows for an increase in number and size of targeted loci. Substitution rate estimates for each of the 50 loci are provided,and an overview of the variation in substitution rates among a large number of low-copy nuclear genes in plants ispresented for the first time. Aligned sequences of major species lineages of Medicago and its sister genus are made availableand can be used in further probe development for sequence-capture of the same markers.

    How liana loads alter tree allometry intropical forests2016In: Plant Ecology, ISSN 1385-0237, E-ISSN 1573-5052Article in journal (Refereed)
    Abstract [en]

    Intense competition with lianas (woodclimbers) can limit tree growth, reproduction, andsurvival. However, the negative effects of liana loadson tree allometry have not yet been addressed. Weinvestigated the hypothesis that liana loading on treecrown alters tree’s allometry, expressed throughslenderness (height–diameter ratio). The relationshipbetween trunk slenderness and percentage of treecrown covered by lianas was investigated for 12 treespecies from 10 fragments of the SemideciduousSeasonal Forest in Southeastern Brazil. We also testedwhether the relationship between slenderness andwood density differ between trees without lianas andtrees heavily infested. Liana loads significantly alteredtree allometry by decreasing slenderness, even whenlianas covered less than 25% of tree crown. Heavywoodspecies decreased their trunk slenderness in agreater ratio than light-wood species. Our findingsindicate that liana infestation shifts tree allometry, andthese effects are stronger on heavy-wood tree species.
