Drastic mycorrhizal community shifts in Sceptridium ferns during the generation transition from fully mycoheterotrophic gametophytes to photosynthetic sporophytes

New Phytologist, Volume 245, Issue 4, Page 1705-1717, February 2025.
Summary Many plant species experience a prolonged subterranean phase during which they rely entirely on mycorrhizal fungi for carbon. While this mycoheterotrophic strategy spans liverworts, lycophytes, and ferns, most empirical research has centered on angiosperms.

Functional Ecology, Volume 39, Issue 1, Page 209-225, January 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Mycoheterotrophs are non‐photosynthetic plants that obtain all of their carbon requirements through parasitizing mycorrhizal fungi. They originated from the autotrophic ancestors and usually have more specific relationships with fungi than that of green plants, for ...

The Contribution of Hydric Habitats to the Richness of the Cape Fynbos Flora

Diversity and Distributions, Volume 31, Issue 1, January 2025.
ABSTRACT Aim The Cape Fold Belt Mountains, underlying the Cape fynbos flora, facilitate widespread moisture collection and groundwater availability across the region, with importance for maintaining hydric habitat niches. We assessed the contribution of hydric habitat‐associated species (HH species) to the richness of this flora, and how this varies ...
