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.
