Seagrass species diversity in Tanzania based on morphological and molecular data

Nordic Journal of Botany, EarlyView.
Seagrass diversity along the Tanzanian coast has been documented mainly through morphology, with limited molecular reference data available for Tanzania and the wider Western Indian Ocean. This study combined morphological identification with nuclear ribosomal internal transcribed spacer (ITS) and plastid ribulose‐1,5‐bisphosphate carboxylase/oxygenase

Biogeography and diversification patterns in the Irano‐Turanian biodiversity hotspots inferred from a molecular phylogeny of the subendemic Iris subgenus Scorpiris (Iridaceae)

Nordic Journal of Botany, EarlyView.
The Irano‐Turanian Floristic Region harbors a rich flora, but our understanding of the development of this diversity is limited by a lack of data on phylogenetic relationships and biogeographic patterns of endemic and more widespread plants. Hypotheses of in situ diversification versus allopatric diversification were tested using Iris subgen. Scorpiris,

Floristic similarity and dispersal syndromes in a rocky outcrop in semi-arid Northeastern Brazil.

Revista de biologia tropical, 2015
Floristic studies provide valuable information on species richness in a region, and are particularly important if these areas belong to less studied environments, such as rocky outcrops, that may increase our knowledge. An important aspect for species colonization includes the mechanisms of diaspores dispersal in each community; these are essential to ...

Taxonomic revision of the genus Tzveleviochloa (Poaceae, Aveninae) in India

Nordic Journal of Botany, EarlyView.
The taxonomy of Tzveleviochloa in India is revised based on morphological evidence, comprehensive observations of herbarium specimens and field records, and several botanical explorations in the study area. The accepted diversity is increased from two to five species, including two recently described species. The genus is distributed in the Western and
