Until now, it hasn’t been possible to get the DNA out of a pressed dried plant (herbarium specimen) without destroying part of it by removing a leaf and grinding it up. But new research by scientist Lara Shepherd has proven that you can use an eraser to ‘rub off’ the DNA.Read more

Karaka, with its large shiny leaves and bright orange fruit, is one of New Zealand’s most distinctive trees. But in pre-European New Zealand, karaka was much more than just a handsome tree – the kernels of its fruit provided an important food source for Māori. This was despite the poisonousRead more

Today is World Science Day for Peace and Development, but science is happening at Te Papa every day . In addition to research being conducted within Te Papa, each year we also loan hundreds of science collection specimens to researchers all around the world. Researchers study our specimens to improve our collectiveRead more

‘The bloke threw such a jandal!’ The only reason a bloke could throw a jandal (aka a tantrum), is because of  Morris Yock of Onehunga. As legend has it, before the 4 October 1957,  there was technically no jandal to throw. In 1957 Yock produced a version of the Japanese sandal inRead more

A key principle in the scientific classification of animals, plants, and other living things is that the system of scientific names reflects their relationships. This is because there is only a single evolutionary history, and it provides an objective basis by which to name life. As we learn more aboutRead more

I’m a co-author of a just-published scientific paper examining the evolution and classification of the Arthropteris climbing ferns. The paper was a real international collaboration, involving authors from China, Netherlands, France, United Kingdom, and New Zealand. It is unclear how many species there are of Arthropteris – probably somewhere betweenRead more

Moin! That is how you say Kia ora or Hello in Oldenburg, which is where my family and I have been living since August 2012. As I near the half-way point in my 18-month fellowship, I thought I would show you where I am living, update you on what IRead more

Recently I have been obtaining DNA sequences from some of the fern samples collected by Te Papa Botany curator Leon Perrie on his recent trip to New Caledonia. We aim to determine the relationships of these New Caledonian ferns to other ferns around the world, including those from New Zealand.Read more

Aside from ferns, my main research interest is the group of trees known as Pseudopanax, for which I collaborate with Lara Shepherd from the Allan Wilson Centre. Blog posts on ferns Blog posts on Pseudopanax Pseudopanax includes the lancewoods and five-fingers. Several of the species are popular in cultivation, includingRead more

The rare, tetraploid maidenhair spleenwort  (Asplenium trichomanes subsp. quadrivalens) has only recently been rediscovered in New Zealand.  Several people have contacted me with possible additional sightings. As described by the Scoop website, Jack Ritchie had a maidenhair spleenwort self-sow on a rock used to construct a water feature in hisRead more
