Comparative plastomes and phylogenetic analysis of seven Korean endemic Saussurea (Asteraceae).

Background: Saussurea is one of the most species-rich genera in the Cardueae, Asteraceae. There are approximately 40 Saussurea species distributed in Korea, with nearly 40% of them endemics. Infrageneric relationships remain uncertain due to insufficient resolutions and low statistical support.

Global and regional drivers of abundance patterns in the hart's tongue fern complex (Aspleniaceae).

Background And Aims: The hart's tongue fern (HTF) complex is a monophyletic group composed of five geographically segregated members with divergent abundance patterns across its broad geographic range. We postulated hierarchical systems of environmental controls in which climatic and land-use change drive abundance patterns at the global scale, while various ecological conditions function as finer scale determinants that further increase geographic disparities at regional to local scales.

Methods: After quantifying the abundance patterns of the HTF complex, we estimated their correlations with global climate and land-use dynamics.

The complete chloroplast genome sequence of Akasawa, a rare fern in South Korea.

We sequenced the complete chloroplast genome of Akasawa (syn: L. subsp. (Komarov) Rasbach, Reichstein & Viane), which is designated as a rare species in South Korea.
