Diversity of ferns and lycophytes in Brazil
TLDR
This compilation of ferns and lycophytes in Brazil is an update of the one published in 2010 and shows that the richest phytogeographic domain continues to be in the Atlantic Rainforest which also has the largest number of endemic and threatened species.
Lycopodiaceae in Brazil. Conspectus of the family I. The genera Lycopodium, Austrolycopodium, Diphasium, and Diphasiastrum
A conspectus of the Lycopodiaceae in Brazil is presented, following a generic classification based on anatomy, chromosome numbers, spores and gametophytes, as well as recent molecular studies. The
Chromosome numbers and their taxonomic implications for eight Brazilian andropogons (Poaceae: Andropogoneae)
TLDR
Diploid counts for A. macrothrix and virgatus support the morphological affinities of these two species to other species complexes within Andropogon.
Caudex growth and phenology of Cyathea atrovirens (Langsd. & Fisch.) Domin (Cyatheaceae) in secondary forest, southern Brazil.
TLDR
Over five years (2004-09), the annual mean caudex growth varied between 1.19 and 2.50 cm and the plants appeared to have an ability to maintain a relatively stable amount of leaves throughout this period, as expected for forests in non-seasonal climate.
Distribution patterns of ferns and lycophytes in the Coastal Region of the state of Rio Grande do Sul, Brazil
A survey of ferns and lycophytes of the Coastal Region of the state of Rio Grande do Sul (CRRS) was performed based on field work and collections of the main regional herbaria. The following were
Epiphytic ferns in swamp forest remnants of the coastal plain of southern Brazil: latitudinal effects on the plant community
Community structure and spatial distribution of epiphytic ferns in swamp forest remnants along the coastal plain of the state of Rio Grande do Sul were analyzed. A total of 440 trees were sampled in
Biodiversity and spatial distribution of epiphytic ferns on Alsophila setosa Kaulf. (Cyatheaceae) caudices in Rio Grande do Sul, Brazil.
TLDR
Considering that the majority of the epiphytes are habitual and that some of them occur exclusively or preferentially on tree ferns, the maintenance of these host plants in the vegetation is essential for the conservation of epipHYtic species.
Germination and sporophytic development of Regnellidium diphyllum Lindm. (Marsileaceae) in the presence of a glyphosate-based herbicide
TLDR
Application of glyphosate to agricultural areas may have negative impacts on the vulnerable fern R. diphyllum, a vulnerable heterosporous fern which grows in areas subjected to flooding and humid soils which frequently are alterated by agricultural activities.
