Despite major conservation efforts, populations of New Zealand’s iconic kiwi are more vulnerable than people realise - Hot off the press

Guest Author May 13, 2021

Isabel Castro, Massey University   Kiwi are moved between populations to lower the risk of inbreeding. Maungatautari Ecological Island Trust, CC BY-SA Like many endangered species, Aotearoa’s flightless and nocturnal kiwi survive only in small, fragmented and isolated populations. This leads to inbreeding and, eventually, inbreeding depression — reduced survival and fertility of offspring. Mixing kiwi from different populations … Read More

Forensics and ship logs solve a 200-year mystery about where the first kiwi specimen was collected - Hot off the press

Guest Author Apr 14, 2021

Paul Scofield, University of Canterbury and Vanesa De Pietri, University of Canterbury The flightless kiwi is an iconic bird for New Zealanders, but all five species are threatened by habitat loss and introduced predators. Recent genomic analysis focused on one species, the South Island brown kiwi or tokoeka, suggests several as yet undescribed lineages. Before these can be fully … Read More

Kiwi and tuatara could be ancient foes - Wild Science

Helen Taylor Jan 25, 2019

What happens when you reunite two species that have been separated for centuries by human activity? According to our latest research, they might turn out to be old rivals. A landscape of species separation New Zealand is a pretty unique place when it comes to biodiversity. However, it’s unique in some negative ways too. Thanks to human activity, many … Read More

Through the looking glass: Fossils reveal a Miocene Wonderland at St Bathans - Lost Worlds, Vanished Lives

Nic Rawlence Mar 19, 2018

It’s the height of the Central Otago summer – barren, dry and dusty. Driving down the gravel road to St Bathans, we’re travelling back in time, down the rabbit hole to a world long gone. Only ghosts remain of this lost world and that’s what we’ve come here to find. The fossilised bones of a myriad of animals dating back … Read More

Step 5, release your mammoth: NZ scientists tackle de-extinction consequences - Wild Science

Helen Taylor May 09, 2017

Most research on de-extinction focuses on the technology behind making it happen. It’s refreshing to see a group of conservation scientists examining what happens when you release these species into the wild. What comes after de-extinction? The latest issue of the  journal Functional Ecology has a special feature on de-extinction. Unless you’ve been living under a rock, you won’t have … Read More

De-extinction dilemma: Bring back the moa or save the kiwi? - News

John Kerr Feb 28, 2017

Adding previously-extinct species to our conservation checklist will strain already tight conservation budgets, say a team of New Zealand and Australian scientists. Little Bush Moa, Anomalopteryx didiformis. © Te Papa. De-extinction – resurrecting extinct species with the help of modern technology – has been largely confined to the realms of sci-fi. But now technology is catching up with the fantasy. Read More

‘Conservation by numbers’ hides genetic dangers in endangered species - Wild Science

Helen Taylor Jan 18, 2017

How do we know when a threatened species is ‘safe’? A new study featuring one of New Zealand’s iconic kiwi species suggests increasing population size might not be enough – an increase in numbers doesn’t always cut it for conservation… Saving threatened species tends to be a numbers game. We often use population growth as a proxy for population … Read More

Ice ages led to ‘explosive’ diversity in Kiwi species - News

John Kerr Sep 01, 2016

Ancient walls of ice separating kiwi populations have left their mark in the DNA of New Zealand’s most iconic species. A new study published this week in PNAS has revealed the enormous impact historic cold snaps had on the evolution of kiwis. Researchers based in Canada, in collaboration with Department of Conservation scientists, examined a database of kiwi DNA across the geographic … Read More
