Se realiza un estudio macroflorístico del afloramiento mioceno de Izarra (Alava, Espana). Los fósiles vegetales se han encontrado sobre o en el interior concreciones calcáreas formadas fondos lacustres hipersalinos donde desarrollaron velos microbianos. Este ha permitido inferir la presencia 31 taxones, pertenecientes a las divisiones Pteridophyta, Pinophyta y Magnoliophyta. El análisis asociac...

This paper presents a paleoenvironmental reconstruction from palynological analyses of a sedimentary core of Holocene age, drilled at municipality of Garopaba (Santa Catarina), Southern Brazil. A total of 46 samples was collected for palynological analyses in the 450 cm-long core PCSC-3, as also three samples for radiocarbon dating and granulometric analyses. The palynological content includes ...

The fern Blechnum sprucei grows in Mesoamerica (Costa Rica) and South America, from Colombia to Bolivia, SE and centre of Brazil, Paraguay and Argentina. It is a distinctive, somewhat vulnerable, mostly orophilous species. Fresh and dry herbarium material was used for this study. Herbarium material for anatomical studies comes from CTES, BA, LP, MA, SI and UC (Holmgren et al. 1990). Selected re...

The fern flora of the world (Pteridophyta) has direct evolutionary links with the earliest vascular plants that appeared in the late Devonian. Knowing the mycobiota associated to this group of plants is critical for a full understanding of the Fungi. Nevertheless, perhaps because of the minor economic significance of ferns, this niche remains relatively neglected by mycologists. Cercosporoid fu...

Ferns (Pteridophyta) have a high diversity of species and are able to live in variety environmental conditions. an ecological function (ground cover, producer, bioindicator) economically (as food, medicine, crafts).
