VOICES Ideas and Insight From Explorers
Last summer after visiting Great Mercury Island I had the brief opportunity to visit nearby Slipper Island off the coast of the Coromandel. With only a weekend on the island, I set out to perform a ‘bioblitz’ terrestrial fauna survey.
St Kilda is a remote island group in the North Atlantic off the coast of Scotland. Having made it to Scotland, and then the Outer Hebrides, it made sense to hop one more island to what was once the very edge of the world.
This month two major invasive species meetings are being held in Britain. First is the Island Invasives conference in Dundee, and later in the month the British Ecological Society symposium on the macroecology of alien species. Each conference will give a unique perspective on the science and management of invasive alien species around the world.
Invasive alien species are the major threat to islands by most metrics, and two open access papers published this week highlight this threat in different ways.
Tiny rock stacks around the world have critical value for conservation but are often neglected. Yesterday I visited a number of such small rock stacks in New Zealand’s Hauraki Gulf to check on their status.
Easter provided an opportunity to hike in the mountainous Southern Alps of New Zealand and to seek out some of the less common birds of New Zealand. We were not disappointed with sightings of some of the endemic residents of the mountains such as rock wren and kea.
Leptospirosis is an infectious bacterial disease found in mammals, particularly associated with rodents. Common in the third world and tropical areas, of high rodent density, it may come as a surprise that New Zealand has one of the highest leptospirosis rates in the world.
Over two years ago the NEXT foundation announced start-up funding for the new R&D company Zero Invasive Predators (ZIP). This past week I visited their intensive field site at Bottle Rock peninsula in the Marlborough Sounds for an update.
A study released this month has illustrated that the rate of species introductions to locations outside their native range is increasing faster than ever.
Pétrel noir de Bourbon may sound like an exotic drink, but it is actually one of the rarest birds in the world. It is so rare, that it has taken a dedicated team of conservationists 15 years just to find their breeding grounds.
This year the Biological Heritage National Science Challenge in New Zealand launches its project on high tech solutions to invasive mammal pests, hosted by the University of Auckland. The high tech solutions project aims to deliver the long-term science solutions which will become a part of Predator Free New Zealand. In July 2016 the New…
Last week I bore witness to the re-wilding of an entire island ecosystem. Invasive mammalian predators were eradicated from Ahuahu (Great Mercury Island) in 2014, and the original predators and keystone species are now returning naturally.
Invasive alien species are now found on every corner of the planet and rank higher than climate change as a current threat to endangered species. So then why, despite all the scientific evidence of negative impacts from invasive species, would people be resistant to taking action against them?
Brown rats are found throughout the world, on its continents and islands, affecting human health and biodiversity, but where did they originally come from? Researchers this month sought to answer that question when they released a global phylogeography of brown rats from cities and islands around the world.
On Tetiaroa Marlon Brando wanted to “to maintain the natural beauty of the atoll setting” and as our expedition draws to a close we too are marvelling at the natural marine and terrestrial beauty of the atoll.
