Rat Eradication on Ilha do Meio

In Brazil WWF is partnering with TRIADE to undertake a trial rat eradication on Ilha do Meio, one of the small offshore islands of Fernando de Noronha. I visited the island this week so that the team undertaking the project could bring me up to speed on their progress so far.

Native Invasives

Like all science, invasion biology depends on clear and strict definitions. The concept of a native invasive species therefore sounds implausible, but is exactly what I have found on Fernando de Noronha.

Amazon Biodiversity Monitoring in Ducke Reserve

Monitoring of biodiversity is a challenge, but visiting Ducke reserve in the Amazon I am able to see one of the gold standards for long-term biodiversity research.

The Value of Birds in Colombia’s Post-Conflict World

by Dr. R. Scott Winton As we peer through the fog in the pre-dawn twilight, the birds we see are anonymous silhouettes. Once the tropical sun breaks through the thickness of the cloud forest, bright jewels of color are illuminated. “There it is!” says José, somehow both whispering and shouting. In the branches overhead appears…

Wildlife on Islands of the Rio Negro

Touring through the Amazon I had the unique opportunity to spend a day visiting the small seasonally flooded islands of the Rio Negro. This dynamic landscape plays a huge role regulating local biodiversity.

Giving To Get: Reciprocity Among Mountain Lions

Please Note: This is the first of two blogs about a research paper published today in Science Advances providing the first evidence of complex social strategies in any solitary carnivore—and showing that mountain lions in particular are more social than previously thought. Part Two will chronicle how territorial males structure social interactions among mountain lions.…

How to Seabird in the Dark

I’m on a clifftop in the dark, on a remote island in New Zealand’s Hauraki Gulf. An inky sea lies below, unfamiliar constellations glitter above, and a bird has just flown straight into my hand. Other pale squeaking shapes are brushing by me and bumping into me. A few minutes ago one smacked me in…

In the 1992 film Medicine Man, biochemist Robert Campbell, played by actor Sean Connery, searches for new drugs in the Amazon’s vast rainforests. There Campbell finds a cure for cancer not in the rainforest’s rare flowers – which don’t have “juju,” or the power to heal – but in an indigenous ant species. All is looking…

Life at the Southern Limits of New Zealand

Rakiura / Stewart Island is the southern-most inhabited point of New Zealand. Here, islanders carve out an existence for themselves among the harsh but beautiful environment.

Do Mountain Lions Rival McDonald’s?

Stinky dead meat. Oddly, I’ve come to love the stench of it, even though it sometimes turns my stomach. It’s become a badge of honor and a symbol of what I do, hiking long days in search of prey killed by mountain lions. Sometimes the stink helps me locate the carcass, or the sounds of…

Origins of a Mysterious Arachnid Revealed

Reconstructing schizomid history in Micronesia led us to tackle the most fundamental questions about these animals, namely, what are they, where did they come from, and when did they arise?

The Social Side of Pest Management

Plans to manage pest species are becoming increasingly larger in scale and ambition. The outcomes of such programmes can have just as important impacts on the resident human communities as the plant and animal communities.
