Fig. 2 in Heracleum Sosnowskyi Manden. Monitoring In Protected Areas - A Case Study In Rēzekne Municipality, Latvia
Fig. 2. Two studied sites in Rāzna National Park in Rēzekne municipality, Mākoņkalna village, Jegorova. Polygon No. 14 - the largest increase of Heracleum sosnowskyi cover from 2012 to 2016 among the studied sites, Polygon No. 15 – the largest new site found in 2016 (Table 2). Yellow stripes - H. sosnowskyi cover in 2012, purple colour – H. sosnowskyi cover in 2016 (Author: Elīna Tripāne).

Fig. 1 in Taxonomic review of the umbelliferous taxa Heracleum moellendorffii complex in Korea based on molecular phylogenies of nuclear ribosomal ITS sequences
Fig. 1. Cladograms inferred from the analysis of 29 nuclear ribosomal DNA ITS1 and ITS2 sequences from the genus Heracleum and an outgroup. (A) The strict consensus of two minimal length 138-step trees derived from equally weighted maximum parsimony analysis of combined nuclear rDNA ITS and 5.8S sequences (CI's with and without uninformative characters=0.91 and 0.89, respectively; RI=0.95). Numbers above nodes indicate the number of times a monophyletic group occurred in 100 bootstrap replicates; decay values are presented below. (B) The Maximum likelihood tree using a transition/tranversion rate ratio of 1.5. Branch lengths are proportional to the number of expected nucleotide substitutions per site. Boxes A, B, and C indicate clades H. maximum-moellendorffii, H. subbipinnatum, and H. sphondylium, respectively.
Dataset for research paper "Heracleum sosnowskyi plants frost-resistance assessment in laboratory and field experiments"
<p>Dataset for research paper "Heracleum sosnowskyi plants frost-resistance in laboratory and field experiments". </p> <p>The <em>Heracleum sosnowsky</em> plants has low freezing tolerance and die in temperature range minus 6–12 °С. Snow cover provides stable soil temperature (not lower than minus 3 °С) and is the only factor that ensures the survival of <em>H. sosnowsky</em> plants in the regions with cold winter. The <em>H. sosnowsky</em> frost tolerance is higher in autumn (up to minus 12 °С) and became lower at spring (minus 5–7 °С). These results can be explained by absence of deep dormancy in <em>H. sosnowskyi</em> meristem tissues and gradual change of carbohydrate content in them during the cold period. The seeds have high freezing tolerance after its formation but lost it after stratification. The field experiments were carried out by participants of citizen science project “Moroz”. It was shown that <em>H. sosnowskyi</em> plant eradication probability with the help of snow removal completely depends on weather conditions. This method can be used only on the territories where the use of herbicides is prohibited and only in the regions with minimal temperature in January – Febrary not higher than minus 25 °С. The dataset with all measurements made during the experiments is available on the site of “Moroz” project (<a href="http://proborshevik.ru/%20">http://proborshevik.ru</a>).</p>
