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

But a newly discovered fossil reptile suggests this theory does not
This post is inspired by Smiv’s reminiscences about cinnabar moth caterpillars when commenting on my previous blog entry. Also, as adult cinnabar moths are on the wing this time of year in New Zealand summer and sightings always generate a number of calls to Te Papa’s entomology department, I thought
Last weekend, when I should have been writing grant applications, I was dragged out for a bush-walk. However, my arm didn’t have to be twisted too hard, since it was a fine day and the track between Kiriwhakapapa and Blue Range is lovely (although steep). Alseuosmia pusilla was abundant along
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
