Brief Overview

The New Zealand Cyatheaceae (Tree Fern) is a relatively unstudied group of plants, and Classification of Cyatheaceae Species in New Zealand is a contentious issue.

Currently, classification is based on a number of varying morphological characters, but this classification system seems to be based almost completely on the preference of the Author.

New techniques in Biotechnology have allowed scientists to gather an extensive data set of Nucleic acid and Protein sequences, which may be better indicators of evolutionary lineages and Classification.

Unfortunately, to date, there has been VERY liitle sequence data collected for Cyatheaceae Species... especially New Zealand....


Molecules..................... or Morphology????????



Project Materials

In order to construct Molecular Phylogenies,
using Nucleic Acid Sequences from numerous loci,

Cyatheaceae (Tree Ferns) Phylogenies

In this workspace, you have been provided a number of Nucleic Acid sequences from Cyatheaceae species, in addition to sequences of related species. These sequences are from various loci, and can possibly be used to create a new Classification system for New Zealand Cyatheaceae. Does the molecular data support a current classification system?
