  • Fossil lamp shell (brachiopod) Pachymagas hectori Thomson, 1920; holotype BR.001339, Landon Creek, near Oamaru, greensands. Named after Allan Thomson’s predecessor as Director of the Colonial Museum (later Dominion Museum), Sir James Hector

Our national museum’s third director was New Zealand’s first Rhodes Scholar, but was cut down in his prime. Te Papa turned 150 years old on 8 December 2015. To celebrate 150 years since the opening of the Colonial Museum in Wellington, the exhibition ‘You called me WHAT?!’ is open on Level 3 until the end… Read more »

Unforgettable names for a new forget-me-not species

https://www.tepapa.govt.nz/visit/whats-on/exhibitions/you-called-me-what-150-years-scientific-discovery-te-papa

We asked you to suggest a species name for a newly discovered New Zealand forget-me not. In addition to some creative descriptive and geographic names, many of your suggestions were commemorative. The practice of naming species after famous people (real or fictional) dates back over 250 years. Are such names just a gimmick, or an effective means of promoting… Read more »

When do crops lose genetic variation? The case of rengarenga.

The delicate flowers of rengarenga with their multicoloured stamens.

The shift from hunting and gathering to cultivating crops and livestock was one of the most important developments in human history. But despite its significance, many questions still remain about how crops were first domesticated. One much debated question has been at what point during domestication is genetic diversity lost? Many modern crops have very… Read more »

The Kerguelen Islands are among the most remote islands on the planet, lying in the middle of the southern Indian Ocean about 7300 km west of New Zealand (or 17,000 km east if you prefer). Yet they have at least two unlikely connections with New Zealand – a plant and a dolphin. And both are… Read more »

A glimpse of ancient Mauritius: Ile aux Aigrettes, restoration island

I first heard of Ile aux Aigrettes at a conference on island pest eradications held in Auckland in early 2001. A delegate from Mauritius spoke about a failed attempt to eradicate Indian musk shrews from the 25 ha island, which had already been cleared of feral cats and ship rats. The island next registered in… Read more »

After 36 hours at Port aux Français, it was time for Charly Bost and me to head into the field again. We were accompanied by Aymeric Fromant, another IPEV ‘VSC’ (Volontaire Service Civique) volunteer. There are a dozen such ‘volunteers’ on Kerguelen each year, with two (Côme Rebaudet and Aymeric Fromant in 2016) focused on… Read more »

The Crozet Islands are one of three subantarctic island groups in the southern Indian Ocean that together form the ‘Terres Australes’ of the Terres Australes et Antarctiques Françaises (TAAF). They are large islands (though much smaller than Kerguelen, which we visited next), with the two largest islands both exceeding 13,000 ha (in contrast, Campbell Island… Read more »
