  • As an endemic species, P. nigra can be considered on the verge of extinction in. (cabi.org)
  • As an endemic species, P. nigra can be considered on the verge of extinction in a large part of its natural range, particularly in west and central Europe, because its natural habitat is gradually being reduced by human activity and because it easily hybridizes with other species (especially P. x canadensis ) and with its fastigiate form var.

  • Similarly, some species of Silybum that occur as weeds, also are cultivated for seeds that yield vegetable oil and pharmaceutical compounds such as Silibinin. (wikipedia.org)

  • hybridization
  • In other cases hybridization has been invoked without much evidence as an explanation for Cirsium variants encountered in herbaria or in the field. (efloras.org)
  • I have seen no documentation of hybridization between native American Cirsium species and introduced Eurasian taxa. (efloras.org)
  • Although further research is needed, it seems that the concept of several taxa as product of hybridization between P. spinosa and cultivated plum species has been supported by our study. (springer.com)
  • Butterflies
  • Cirsium muticum is as host for some species of butterflies and moths, including the swamp metalmark butterfly (Calephelis muticum), a species that is currently undergoing risk assessment in the United States. (wikipedia.org)
  • Some species are cultivated in gardens for their aesthetic value and to attract butterflies. (wikipedia.org)
  • Carthamus
  • To clarify the phylogenetic relationships of Carthamus species, we performed sequence analysis of the nuclear stearoyl acyl carrier protein desaturase (SACPD) gene and the chloroplast intergenic spacer region between leucine and phenylalanine tRNA genes (trnL-trnF IGS) in 13 taxa of Carthamus.

  • Native species of Cirsium range from sea level to alpine and from boreal regions of Canada to the tropics of Central America. (efloras.org)
  • We propose to add use of plant demography plant while stabilizing or increasing populations of (an assessment of how environmental factors and those native species considered under threat by ecological interactions, for example competition, invasive plants. (deepdyve.com)
  • plants
  • Cirsium muticum, also known as swamp thistle, marsh thistle, dunce-nettle, or horsetops, is a North American species of plants in the sunflower family, native to central and eastern Canada and the central and eastern United States. (wikipedia.org)
  • Relationships among the North American species are apparently complex, and molecular studies have only begun to provide an outline of phylogeny for these plants. (efloras.org)

The species that could not be eliminated in the first screening step irony of this change in risk perception is that specific constitute pool 2 which are tested using more sophisticated and successful agents of the past would have difficul- designs, such as multiple-choice tests using potted plants or ties passing through current approval processes larger cages (screen 2).

  • artichoke
  • For the 23 polymorphic loci, a total of 165 alleles were scored, 135 of which in the artichoke primary genepool, and the remaining ones in the other Cynara species. (springer.com)
  • In the sequenced regions, some SNPs were identified which distinguished artichoke on one side, and cultivated and wild cardoon on the other, while other SNPs were apportioned according to the geographic distribution of Cynara wild species. (springer.com)
  • alpine
  • Cirsium muticum is found mostly in alkaline swamps, wetlands, marshes and low forests but some races have been known to grow in wet alpine climates. (wikipedia.org)
  • Cynara
  • The transferability of microsatellite markers to other Cynara wild species was quite good. (springer.com)
  • Sequencing alleles at three loci showed that, apart from microsatellite length variation, point mutations and insertion/deletions were quite abundant especially when comparing C. cardunculus to the other Cynara species. (springer.com)

  • This suggests either that the diversification has been very rapid or that genetic markers in North American Cirsium mutate more slowly than in most other lineages. (efloras.org)
  • centuries
  • Cirsium muticum is at risk primarily because it is a wetland plant, and North American wetlands have been much reduced in extent over the last two centuries. (wikipedia.org)
  • A wide natural range and the cultivation of Populus nigra over the past centuries makes the taxonomy of the species particularly complex. (cabi.org)
  • found
  • Cirsium muticum has been found across every province of Canada from Labrador and Newfoundland to Saskatchewan. (wikipedia.org)
