Effects of Climate Change Scenarios on Population and Distribution Pattern of Tree–Ferns in Nepal [PDF]

open access: yesEcology and Evolution
By studying the population structure and spatial characteristics, the relationship between tree‐ferns and the environment can be reflected, which has high practical significance.

Transcriptomics and metabolomics analyses provide insights into resistance genes of tree ferns [PDF]

open access: yesFrontiers in Genetics
As ancient organisms, tree ferns play a crucial role as an evolutionary bridge between lower and higher plant species, providing various utilitarian benefits.

Non-linear growth in tree ferns, Dicksonia antarctica and Cyathea australis. [PDF]

open access: yesPLoS ONE, 2017
Tree ferns are an important structural component of forests in many countries. However, because their regeneration is often unrelated to major disturbances, their age is often difficult to determine. In addition, rates of growth may not be uniform, which

rFerns: An Implementation of the Random Ferns Method for General-Purpose Machine Learning [PDF]

open access: yesJournal of Statistical Software, 2014
Random ferns is a very simple yet powerful classification method originally introduced for specific computer vision tasks. In this paper, I show that this algorithm may be considered as a constrained decision tree ensemble and use this interpretation to ...

Historical reconstruction of climatic and elevation preferences and the evolution of cloud forest-adapted tree ferns in Mesoamerica [PDF]

open access: yesPeerJ, 2016
Background Cloud forests, characterized by a persistent, frequent or seasonal low-level cloud cover and fragmented distribution, are one of the most threatened habitats, especially in the Neotropics.

Distribution and morphological variation of tree ferns (Cyatheaceae) along an elevation gradient [PDF]

open access: yesPLoS ONE, 2023
Knowing how species and communities respond to environmental change is fundamental in the context of climate change. The search for patterns of abundance and phenotypic variation along altitudinal gradients can provide evidence on adaptive limits.

Characterization and analysis of multi-organ full-length transcriptomes in Sphaeropteris brunoniana and Alsophila latebrosa highlight secondary metabolism and chloroplast RNA editing pattern of tree ferns [PDF]

open access: yesBMC Plant Biology
Background Sphaeropteris brunoniana and Alsophila latebrosa are both old relict and rare tree ferns, which have experienced the constant changes of climate and environment. However, little is known about their high-quality genetic information and related

Negative density dependence and environmental heterogeneity effects on tree ferns across succession in a tropical montane forest [PDF]

open access: yesPerspectives in Plant Ecology, Evolution and Systematics, 2014
Although tree ferns are an important component of temperate and tropical forests, very little is known about their ecology. Their peculiar biology (e.g., dispersal by spores and two-phase life cycle) makes it difficult to extrapolate current knowledge on

Diversity and distributional ecology of tree ferns of Sri Lanka: A step towards conservation of a unique gene pool

open access: yesCeylon Journal of Science, 2017
Tree ferns are a remarkable group among the lycophytes and ferns. Geographical isolation is suggested as one of the main reasons for local endemism of tree ferns and the island of Sri Lanka has been identified as one of the best demonstration sites to ...

Genome-wide identification of five fern bHLH families and functional analysis of bHLHs in lignin biosynthesis in Alsophila spinulosa [PDF]

open access: yesBMC Genomics
Background The basic helix-loop-helix (bHLH) transcription factors are involved in the biosynthesis of various secondary metabolites. However, genome-wide studies on the bHLH gene family in ferns and their role in lignin biosynthesis remain limited.
