Analyis on the vascular epiphytes of tree ferns in a montane rain forest in Costa Rica

open access: yesRevista de Matemática: Teoría y Aplicaciones, 2009
The relationships between epiphytes and host specifity are known. We investigated the relation between specific epiphytes and tree fern trunks. Only some epiphytes are frequent or very frequent on tree ferns.

Biometry of stomata in Blechnum species (Blechnaceae) with some taxonomic and ecological implications for the ferns

open access: yesRevista de Biología Tropical, 2011
Morphological stomatal traits, such as size, form and frequency, have been subject of much literature, including their relationships with environmental factors. However, little effort have focused on ferns, and very few in the genus Blechnum.

Response of spores and young gametophytes of Cyathea delgadii Sternb. (Cyatheaceae) and Blechnum brasiliense Desv. (Blechnaceae) to different light levels Resposta de esporos e gametófitos jovens de Cyathea delgadii Sternb. (Cyatheaceae) e Blechnum brasiliense Desv. (Blechnaceae) aos diferentes níveis de luz

open access: yesActa Botânica Brasílica, 2007
Light is a limiting factor for fern stablishment because it controls germination of light sensitive spores. The aim of this work was to study the effect of light levels on spore germination in two ornamental ferns native to the Atlantic forest, under ...

Fire Severity and Habitat Type Determine Vegetation Change and Regeneration Time Following Wildfires in Scottish Uplands

open access: yesEcology and Evolution, Volume 15, Issue 7, July 2025.
This study examines wildfire impacts on vegetation composition and diversity across 27 Scottish blanket bog and heathland sites spanning 2–24 years since fire. Vegetation change and recovery were strongly influenced by habitat type and fire severity, with wet moorlands showing resistance to severe burning and dry heathlands experiencing greater initial
