Visiting the Magical Mountain Home of a Giant Ocean Wanderer

For years I’ve dreamed of visiting “Gonydale,” a remote valley reached after a three-hour trek across rivers, beneath towering pinnacle cliffs and through thick lush ferns. It is a lost world and home to some of the last of the Tristan albatross.

Tristan da Cunha Expedition: Preparing the Team, Protecting the Islands

The gear is ready. Now for the most important work: biosecurity.

High tech solutions to invasive mammal pests

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…

Invasion of the Aliens: Body Snatching Worms, Cold Winters May Rout Lakes’ Enemies

Public enemy number one, it might be called: Eurasian watermilfoil. It’s not on the FBI’s Ten Most Wanted list, but maybe it should be, say scientists who study lakes. The invasive weed’s crime? It crowds out native underwater plants, fouls boat propellers and smothers swimming areas in freshwater lakes across the northern U.S. The invader’s…

Why Doubt Invasive Species Impacts?

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?

Saving the Reef: Lionfish in Florida

Lionfish, a brightly-colored, spiny fish that are not native to Florida, are taking over our reefs. How can we fight off this alien invasion? Floridians have come together to fight them off and save the reef.

Combating Lionfish? Try Eating Them!

Lionfish are beautiful. Their bodies are covered in stripes, and they have long, delicate fins that are nearly translucent in places. Native to the Pacific and Indian Oceans, they have unfortunately become not only a nuisance, but a major problem affecting reef health across America’s Gulf of Mexico and Atlantic coastlines. Lionfish were first identified…

Excuse me, waiter, there’s an invasive species in my soup

Co-authored by Erica Cirino After a full day looking at dinosaur bones, taxidermy birds and hieroglyphs at the Yale Peabody Museum of Natural History, I walked through the streets of New Haven in the rain to into a warm, rustic little Japanese restaurant feeling ravenous, excited and slightly nervous. While my official excuse to travel…

Island’s Invasive Species Wreak Havoc: How Did They Get Here?

Invasive cats, rats, and lizards are wreaking havoc on the native species of Fernando de Noronha. How did they all get here?

Fighting Back Lionfish for Invasive Species Awareness Week

In honor of Invasive Species Awareness Week, see how Floridians are working to control invasive lionfish and put them to good use.

500 Years on a Tropic Island in 500 Words or Less

When studying invasive species on a remote island, it helps to know the island’s history. And this one’s good.

Over-Invasion of Invasive Species

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…

Green Snails: Valuable Aliens

By Alison Barrat and Alex Dempsey You don’t have to look too far to find a horror story about an invasive species that has completely disrupted a natural ecosystem. Cane toads in Australia come to mind or pythons in the Everglades or even lionfish in the Caribbean.  But what about introductions that have gone well?…

Lionfish Flare Their Fins to Hunt Together

A new study finds that lionfish—those venomous, striped invaders of reefs in the Caribbean and off of Florida—fan their fins to gather a posse while hunting prey.

International Island Biodiversity Day

The 22nd of May is the International day for Biological Diversity, and this year the theme is Island Biodiversity. Islands house a disproportionate amount of the world’s biodiversity: although less than 5% of the world’s land area, they are home to over 20% of the planet’s terrestrial biodiversity, and in the last 500 years 80%…
