Phenolic compounds in species of the Blechnaceae. [PDF]

Plant Biol (Stuttg)
The occurrence of caffeic acid derivatives in 32 species of Blechnaceae revealed differences in the presence of rosmarinic acid and blechnic acid B, a novel compound in ferns. Abstract Rosmarinic acid and other caffeic and 4‐coumaric acid derivatives are widespread in land plants.

Identification and characterization of BAHD hydroxycinnamoyltransferases in the fern Neoblechnum brasiliense. [PDF]

Plant J
Significance 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 Evol
We 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.

Effective dispersal of fern spore and the ecological relevance of zoochory. [PDF]

Biol Rev Camb Philos Soc
ABSTRACT The mechanisms of fern dispersal are under‐studied and there are few data to support the vectors assumed to drive patterns of sporophyte occurrence and speciation. Although wind is generally the fern spore dispersal vector described in the literature, there has always been competing evidence supporting alternate vectors.

Germinación y frecuencia de esporofitos de dos especies simpátricas de Blechnum (Blechnaceae)

Acta Botanica Mexicana, 2016
Antecedentes y Objetivos: La luz y el agua son recursos que limitan la germinación y el crecimiento de las plantas en los bosques, y el establecimiento influye importantemente en la distribución de las especies.

Fires in rainforests: Quantifying litter bed flammability of cool temperate rainforests in eastern Australia. [PDF]

Am J Bot
Abstract 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.

A Gompertz regression model for fern spores germination

Anales del Jardín Botánico de Madrid, 2015
Germination is one of the most important biological processes for both seed and spore plants, also for fungi. At present, mathematical models of germination have been developed in fungi, bryophytes and several plant species.
