How early ferns became trees [PDF]

open access: yesProceedings of the Royal Society of London. Series B: Biological Sciences, 2001
A new anatomically preserved fern, discovered from the basalmost Carboniferous of Australia, shows a unique combination of very primitive anatomical characters (solid centrarch cauline protostele) with the elaboration of an original model of the arborescent habit.

Allopolyploid speciation accompanied by gene flow in a tree fern.

open access: yesMolecular biology and evolution, 2020
Hybridization in plants may result in hybrid speciation or introgression and, thus, is now widely understood to be an important mechanism of species diversity on an evolutionary time scale. Hybridization is particularly common in ferns, as is polyploidy,

Epiphytic ferns and bryophytes of Tasmanian tree-ferns: A comparison of diversity and composition between two host species [PDF]

open access: yes, 2005
Ferns, bryophytes and lichens are the most diverse groups of plants in wet forests in south-eastern Australia. However, management of this diversity is limited by a lack of ecological knowledge of these groups and the difficulty in identifying species ...

Impact of the Redheaded Pine Sawfly (Hymenoptera: Diprionidae) on Young Red Pine Plantations [PDF]

open access: yes, 2017
The ecology of the redheaded pine sawfly was studied relative to its impact on red pine plantations. An ecological model, which formed the basis for socioeconomic analysis, was constructed.

Genes Translocated into the Plastid Inverted Repeat Show Decelerated Substitution Rates and Elevated GC Content. [PDF]

open access: yes, 2016
Plant chloroplast genomes (plastomes) are characterized by an inverted repeat (IR) region and two larger single copy (SC) regions. Patterns of molecular evolution in the IR and SC regions differ, most notably by a reduced rate of nucleotide substitution ...

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

open access: yes, 2014
In this paper I present an extended implementation of the Random ferns algorithm contained in the R package rFerns. It differs from the original by the ability of consuming categorical and numerical attributes instead of only binary ones.
