A new record of green spore in Lomaria (Blechnaceae, Polypodiospida)
Rodriguésia, 2023 Fern spores play a vital role in dispersal. The unique features of spores, such as size, thickness, and ornamentation can aid in taxonomic decisions and division of groups.

Application of a novel schema for describing fossil fern foliage and investigating taxonomic and morphological change across the Cretaceous-Paleogene boundary in western North America. [PDF]
Am J BotAbstract Premise The Chicxulub asteroid impact at the Cretaceous–Paleogene (K–Pg) boundary triggered a mass extinction 66 million years ago. Ferns thrived in the aftermath of the extinction, evidenced by the well‐documented “fern spore spike.” However, fern macrofossil records across the K–Pg boundary are less understood.

Identification and characterization of BAHD hydroxycinnamoyltransferases in the fern Neoblechnum brasiliense. [PDF]
Plant JSignificance Statement Nine BAHD acyltransferases have been identified and characterized in the fern Neoblechnum brasiliense transferring hydroxycinnamoyl units onto various alcohol and amine acceptor substrates. Kinetic characterization showed that shikimic and quinic acids for ester formation as well as 3‐hydroxyanthranilic acid and tryptamine for ...

Diversity-Elevation Relationships of Vascular Plants in Austral Temperate Ecosystems Are Strata Dependent. [PDF]
Ecol EvolWe investigated diversity patterns of vascular plants of overstorey and understorey vegetation separately per stratum and the influence of anthropogenic disturbances along two elevational transects with contrasting slope aspects in a temperate rainforest and alpine scrub in southern Chile.

Fires in rainforests: Quantifying litter bed flammability of cool temperate rainforests in eastern Australia. [PDF]
Am J BotAbstract Premise Rainforests are usually too wet to burn, acting as natural barriers to fire spread and as refuges for biodiversity. However, climate change is increasing the risk of fire incursion into rainforests. Our capacity to manage these impacts is hindered by limited research on rainforest flammability.
