Botany has recently acquired a unique collection: a special group of calcified red algae known as the corallines. Coralline algae are abundant and ubiquitous throughout the world’s oceans, playing very important roles in marine ecosystems. The encrusting, or crustose, species can form unusual lumpy, warty-looking layers in the intertidal, sometimes completely covering rocks. Perhaps you… Read more »

We have DNA

  • Pseudopanax macintyrei.
  • Pseudopanax macintyrei.
  • Adult tree of fierce lancewood, Pseudopanax ferox.
  • DNA of Pseudopanax on agarose gel after electrophoresis

The first step after collecting samples for genetic analyses is to extract the DNA. Lara and I do this for lancewood and five-finger plants (Pseudopanax) by: freezing a small piece of leaf tissue in liquid nitrogen (-196 degrees C !) and grinding it as finely as possible. adding a detergent to release the DNA from… Read more »

Field-work is one of the best aspects of working as a Natural Environment curator at Te Papa. I get to spend about three weeks a year in the field collecting plant specimens. I’ve recently returned from ten days field-work in the South Island, collecting samples for our research on lancewood (horoeka, Pseudopanax crassifolius) and fierce… Read more »
