Disentangling the effects of glaciers and climate on vegetation is complicated by confounding role that plays in both systems. We reconstructed changes occurring over Holocene at Jøkelvatnet, a lake located directly downstream from Langfjordjøkel glacier northern Norway. used sedimentary ancient DNA (sedaDNA) metabarcoding dataset 38 samples sediment core spanning 10,400 years using primers tar...

Little is currently known about preservation of plant DNA in lake sediments. Most prior information originates from laboratory experiments while systematic field-based studies are still lacking. Here, we used the “g” and “h” universal primers for P6 loop region chloroplast trnL (UAA) intron to amplify 219 surface sediments China Siberia. We introduce (i) percentage sequence counts with best ide...

Polygalaceae is a large family with cosmopolitan distribution, comprising ca. 1,200 species in 27 genera. However, similar to many plant groups, the identification of mostly depends on floral and fruit characteristics; therefore, DNA barcoding could easily warrant corect sterile material. In current study, utility six widely employed barcode loci, namely rbcL, matK, trnL-F region (including trn...

A new species of the New Zealand endemic grass Simplicia, Simplicia felix is described. The new species is segregated from and compared with Simplicia buchananii and Simplicia laxa. Simplicia felix occurs mostly in lightly shaded areas of seasonally dry alluvial forest. A distribution map and an assessment of the conservation status of the new species are presented. Genetic variation in the gen...
