How to contribute to the NZPRN wiki

Welcome

Welcome to the New Zealand Plant Radiation Network (NZPRN) wiki. Here you will find information on research being conducted on species radiation in the New Zealand flora.

The NZPRN is open to everyone interested in plant evolutionary biology. Please contact one of the people of the organising committee if you would like to join. New NZPRN members will automatically receive a login so that they can contribute to the wiki. If you are an existing member of the NZPRN you can register for a wiki login here.

Also check out our NZPRN facebook group!

If you have any comments or questions about the wiki, please do not hesitate to e-mail nzprn.webmaster@anatomy.otago.ac.nz.

What is species radiation?

What are plant species radiations, and why are they important? Understanding how global plant biodiversity arose and is maintained requires an understanding of plant species radiation - a process of diversification that produces morphologically and ecologically distinct, but genetically similar, species from a single founding population. Species radiations are a feature of many world floras including that of New Zealand. Developing our understanding of species radiation will help us to understand the nature, evolutionary potential and adaptability of our flora to environmental change.

Research on New Zealand plant species radiations

The well understood geological and climatic record for New Zealand, together with the simple complexity of our flora provides for a unique model system to investigate plant evolutionary and ecological processes. Some examples of plant groups that have radiated extensively in New Zealand include Asplenium, Blechnum, Celmisia, Dracophyllum, Epilobium, Hebe/Veronica, Ourisia, Pachycladon, and Ranunculus, among others. Making the most of opportunities to study and understand these plants requires interdisciplinary research in palynology, morphology, ecology, physiology and in studies of genetic variation. It requires the collaboration of biologists, mathematicians, physicists, computer scientists, climatologists and geologists.

It is with this collaborative spirit in mind that we would like to introduce the New Zealand Plant Radiation Network (NZPRN). The NZPRN aims to bring together researchers interested in botanical research to promote collaboration and discussion of ideas, methods and projects around several themes including: delimitation of species, ecological drivers of radiation, reconstructing the evolutionary history of species radiations, and evolutionary significance of hybridisation and polyploidy.
