New Phytologist, Volume 205, Issue 1, Page 415-428, January 2015., 2015 Summary This study analyses and compares the genetic signatures of anagenetic and cladogenetic speciation in six species of the genus Robinsonia (Asteraceae, Senecioneae), endemic to the Juan Fernández Islands, Chile. Population genetic structure was analyzed by amplified fragment length polymorphism (AFLP) and microsatellite (simple sequence repeat ...

Wood density variation across an Andes‐to‐Amazon elevational gradient
Journal of Ecology, Volume 113, Issue 9, Page 2370-2385, September 2025.We study how wood density varies along a 3500‐m elevational gradient, spanning from the Andean tree line to the Amazon basin. Our results reveal that wood density decreases from low to mid‐elevations, then increases toward the tree line. These patterns underscore the influence of species composition, life forms such as tree ferns, and local ...

The Evolutionary Dynamics of Apomixis in Ferns: A Case Study from Polystichoid Ferns
Journal of Botany, Volume 2012, Issue 1, 2012., 2012 The disparate distribution of apomixis between the major plant lineages is arguably one of the most paradoxical phenomena in plant evolution. Ferns are particularly interesting for addressing this issue because apomixis is more frequent than in any other group of plants.

Marcescence and prostrate growth in tree ferns are adaptations to cold tolerance
Ecography, Volume 2025, Issue 6, June 2025.Cold tolerance strategies in plants vary from structural to biochemical permitting many plants to survive and grow on sites that experience freezing conditions intermittently. Although tree ferns occur predominantly across the tropics, they also occur in temperate zones and occasionally in areas that experience sub‐zero temperatures, and how these ...

Light and storage on the germination of spores of Dicksonia sellowiana (Presl.) Hook., Dicksoniaceae
Revista Brasileira de Botânica, 1999 Spores of Dicksonia sellowiana are positively photoblastic and reach the maximum percentage of germination at 23 ± 2°C in white light after seven days of imbibition. The pre-induction phase for spores induced by white or red light for 24 hours was 72 hours.
