This blog was written by Mel Dash, who is currently on maternity leave from Te Papa Kererū (New Zealand’s native wood pigeon) are making a comeback but they still need our help so Forest and Bird’s Kiwi Conservation Club (KCC), Kereru Discovery and partners have organised a two week Kererū Count to get an idea… Read more »

I spent yesterday afternoon in the fernery of Otari-Wilton’s Bush, examining two tree fern species from New Zealand’s subtropical Kermadec Islands. More details below, including ‘why?’. But first, a challenge… Each of these Kermadec tree ferns is closely related to a (different) mainland New Zealand species. Can you tell which mainland species? One of the… Read more »

Doodia rasp ferns become Blechnum hard ferns

  • Blechnum neglectum, previously Pteridoblechnum neglectum, found only in north-eastern Australia. Right: Blechnum diversifolium, from New Caledonia. Blechnum diversifolium is more closely related to the species previously placed in Pteridoblechnum than it is to most species of Blechnum. Photos Leon Perrie. Composite © Te Papa.
  • Blechnaceae ferns are common in several parts of the world. For instance, all New Zealanders will be familiar with kiokio and its relatives in the genus Blechnum, colloquially known as “hard ferns” because of their coriaceous fronds.  Kiokio (Blechnum novae-zelandiae) is a common sight on road cuttings, amongst other habitats, and occurs throughout the country. Photo Leon Perrie. © Te Papa.
  • Left: rasp fern, Blechnum parrisiae, previously called Doodia australis, occurs in both Australia and New Zealand. Right: Blechnum gibbum, from New Caledonia. Blechnum gibbum is more closely related to the species formerly placed in Doodia than it is to most species of Blechnum. Photos Leon Perrie. Composite © Te Papa.
  • Blechnum orientale, in Fiji. Most species of Blechnum in New Zealand are “dimorphic”, with obviously different fertile and sterile fronds. (The exception is Blechnum fraseri, which is only partially dimorphic.) However, many overseas Blechnum are “monomorphic” like Blechnum orientale, which is widespread in the tropics from Asia through Australia to the Pacific.  Photo Leon Perrie. (c) Te Papa.

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 about these evolutionary relationships, scientific names… Read more »

Today we’ve been hearing about the most recent addition to Te Papa’s scientific collections, a new colossal squid Mesonychoteuthis hamiltoni. We’re playing host to a dozen or so media representatives as well as our own live-streaming film crew, who are following intently the activity of five visiting squid scientists from AUT, led by Dr Kat… Read more »

The fascination of squid
