  Keywords: geospatial analysis; species richness; species range; species distribution modeling

  Abstract Although the distribution of Tulipa species in Uzbekistan is well documented, there is no clear understanding of the importance of three classes of environmental variables, climate, soil type, and topography, as determinants of their distribution. We mapped the richness of Tulipa species in…

  Keywords: Central Asia; identification key; Iris; Juno; typification

  Abstract The novel, phylogeny-based classification of Iris s.l. in the Mountains of Central Asia biodiversity hotspot has been developed. Fifty seven species are accepted and classified into 14 sections. The majority of accepted species (38) belong to the juno irises, which have a centre of their diversity…

  Keywords: plastome structure; comparative genomics; codon usage bias; hypervariable regions; lineage diversification; evolutionary history

  Abstract Scutellaria L. (Lamiaceae) is a diverse and pharmacologically important genus with significant species richness in Central Asia. Here, we sequenced and analyzed complete chloroplast genomes of 14 Scutellaria species from Uzbekistan and adjacent regions, integrating them with 184 publicly available…
