Norfolk Island is an external territory of Australia, currently governed by its own general assembly. Norfolk Island is the last island around New Zealand from which we need a genetic sample of the invasive rats to complete our phylogeographic map of invasive rats around New Zealand and neighbouring islands.
Without island biosecurity pests will rapidly recolonize islands from which they have been eradicated, or worse still colonise islands for the first time. Only with a rigorous audited biosecurity programme can pest-free status be maintained.
Colleagues from Mexico have just announced the successful eradication of introduced mammals from the massive Banco Chinchorro reef complex off the Yucatan peninsula. Mexico has aggressively tackled the problem of invasive species eradication on islands over the past decade.
Having just returned from Fernando de Noronha the plight of tropical islands under attack from invasive species is still at the forefront of my thoughts. Can the techniques we have developed in temperate latitudes on uninhabited islands be applied so readily to inhabited tropical islands?
The bird species that have lived on Fernando de Noronha for millions of years have new predators to battle: introduced cats, rats, and a three-foot Brazilian lizard. Can they survive?
Invasive cats, rats, and lizards are wreaking havoc on the native species of Fernando de Noronha. How did they all get here?
The last twenty-four hours on Fernando de Noronha have been non-stop, non-sleep, and action filled, and not just because it’s been Carnival in Brazil.
This week on National Geographic Weekend, join host Boyd Matson and his guests as they set a speed record on El Capitan, prosecute poaching kingpins, share survival tips for extreme weather, dig up clues on ancient tsunamis to study for future risk, hold our breath to survive a surfing disaster, call the Malagasy military for an airlift, understand the evolution of New York’s rats, and mourn the Sherpa guides and porters lost on Everest.
A surfing goat has inspired its own YouTube channel and children’s book, but it’s not the only pet that’s been trained to catch waves.
With invasive species colonising more and more locations it is only a matter of time before two similar species come in to contact with one another. Looking at the existing literature it seems there are already many cases of this, such as in similar species of foxes, wasps, ants, crayfish and plants. Our work looking…
In 2014 New Zealand celebrates 50 years of rodent eradications, following the confirmation of successful eradication of Norway rats from Maria Island in 1964 by the Forest and Bird Protection Society with assistance from Don Merton, and a grant of 5 pounds from the Wildlife Service. At that time only 0.5% of New Zealand’s islands…

Dogs aren’t the only creatures with outstanding sniffers: Fruit flies, honeybees, and even rats can detect disease in people.
Completely eradicating pests from an island is a major conservation achievement, such as the recently announced eradication of goats from 15,380 ha Aldabra atoll. However, reliably confirming the absence of a species is difficult, bringing to mind the famous mantra ‘absence of evidence is not evidence of absence’. So how do eradication managers finally confirm…
Black Plague Gravesites Uncovered Excavations in the spring of 2013 for London’s Crossrail, a large railway project under constructions in the city, uncovered a series of graves from the 14th century thought to be people who died of the Black plague. This terrible disease ravaged the cities of Europe during this periodic killing an estimated…
