Phylogenetic Analyses of rdcL and Nuclear Ribosomal RNA Gene Sequences in Dennstaedtiaceae

open access: yes, 1995
Sixteen new sequences of the chloroplast gene rbcL were used to assess evolutionary relationships in Dennstaedtiaceae. Sequence data from nuclear 18S rRNA genes from several dennstaedtioid ferns were also analyzed and found to support some of the ...

A Narrative Review of Wild and Semiwild Edible Plants in Ethiopia: Agroecological Perspectives, Ethnic Diversity, Proximate Composition, and Phytochemical Analysis

open access: yesInternational Journal of Food Science, Volume 2025, Issue 1, 2025.
All over the world, wild edible plants are predominantly the sources of famine food. Ethiopia, with food‐insecure populations, needs such food‐supplementing plant groups. The current review article is aimed at presenting a compiled list of the species, showing the diversity of the species, and elaborating on their major threats and values.

Morphological and Genomic Diversity in the Genus Pteridium(Dennstaedtiaceae) [PDF]

open access: yesAnnals of Botany, 2000
Abstract Morphometric comparisons of frond material grown under standardized garden conditions and DNA fingerprinting by arbitrarily-primed PCR were used to assess taxonomic groupings and relationships in the cosmopolitan bracken ferns of the genus Pteridium(Dennstaedtiaceae).

Plastome phylogenomics and new fossil evidence from Dominican amber shed light on the evolutionary history of the Neotropical fern genus Pecluma

open access: yesAmerican Journal of Botany, Volume 111, Issue 10, October 2024.
Abstract Premise Molecular studies based on chloroplast markers have questioned the monophyly of the fern genus Pecluma (Polypodioideae, Polypodiaceae), which has several species of Polypodium nested within it. We explored the delimitation of Pecluma and its biogeographic pattern by evaluating the phylogenetic position of four Polypodium species not ...

Linking topography, soil variability, and early successional vegetation in abandoned gold mines in the tropical rainforest of Colombia's Chocó Biogeographic region

open access: yesRestoration Ecology, Volume 32, Issue 7, September 2024.
Soil fertility heterogeneity is one of the main factors affecting early recovery and plant succession toward a target plant community. This study examined the influence of topography on the diversity and composition of plant communities established in areas degraded by opencast mining in Chocó, Colombia.
