My friends at National Geographic have provided permission for me to share some of the images from the recent discovery of a huge number of new species on and around the south Pacific island of Vanuatu.
Tiny Tropical Island Yields a Wealth of Species
Scientists sampled some 4,000 different mollusk species in Espiritu Santo. Mollusk expert Philippe Bouchet speculates that as many as 1,000 of these could be new species.
Among the finds: this sundial snail, already…

Two nectar-feeding birds from Hawai'i, the kioea (brown-streaked, in middle) and an o'o species (lower left), looked so much like nectar specialists from the western Pacific (two species on right) that taxonomists put them all in the same honeyeater family, the Meliphagidae. All the Hawaiian birds are unfortunately extinct, but DNA evidence shows that their resemblance resulted from convergent evolution, because the Hawaiian birds were actually much…

Tiny Tropical Island Yields a Wealth of Species
November 24, 2008--Even on tiny remote islands, scientists can find an impressive array of life.
During the Santo 2006 biodiversity survey in Vanuatu, 153 scientists from 20 countries fanned out across the remote South…

Two of my ornithologist colleagues, Chris Filardi and Rob Moyle, published a paper in the top-tier research journal, Nature. This paper is especially exciting because it shows that oceanic islands are not necessarily the evolutionary "dead ends" that they have traditionally been portrayed to be. In fact, Chris and Rob's data show that a group of birds have actually accomplished what scientists had never…

I have been in love with New Guinea since I first read about it as a kid. Everything about this tropical island is exotic and fascinating to me, from the large numbers of endemic bird and plant species to the tremendous number of spoken languages -- more than anywhere else on the planet. So I was immediately…

This fascinating creature was discovered in 1998 off the coast of Sulawesi in Indonesia, the mimic octopus is the first known species to take on the characteristics of multiple species. This octopus is able to copy the physical likeness and movement of more than fifteen different species, including sea snakes, lionfish, flatfish, brittle stars, giant crabs, sea shells, stingrays, jellyfish, sea anemones, and mantis shrimp. This animal is so intelligent that it is able to discern which dangerous sea creature to…
grrlscientist | November 10, 2008tags: pets, cutest kitten in the world, streaming video
This video is a 5 minute amateur documentary about Hawai'i's endangered birds and the causes of their decline. The filmographer writes; "This was somewhat a difficult topic and we suffered from a lack of suitable footage of native birds as most endangered birds are not seen regularly as they used to be decades ago. Could have done better for sure, in fact if I had the chance I'd do it over for the sake of sharing the issues of the human impact on island birds." I think this is a great start for a conservation filmographer! [5:14]

French scientist, Ivan Ineich, displays a never-before-seen species of gecko at France's Natural History Museum in Paris. This gecko, formally described with the Latin name, Lepidodactylus buleli, was born in Paris from an egg that was removed from the rainforest canopy on the west coast of Espiritu Santo, one of the larger islands of the Vanuatu Archipelago, east of Australia in the South Pacific Ocean.

I had the most fascinating telephone discussion with Bonnie Zimmermann, Vice President of the Indonesian Parrot Project, about the recent reported rediscovery of several individuals of the rarest cockatoo in the world. This species, known as the Masakambing (Abbott's) yellow-crested cockatoo, Cacatua sulphurea abbotti, is a subspecies of Yellow (Sulfur)-crested…

One of the challenges facing those who believe that evolution cannot create new species is explaining the problem of "ring species." Ring species are a group of geographically connected populations that can interbreed with nearby populations, but cannot breed with those populations that exist at each end of the cline (figure A). These populations…

I have been fascinated by New Guinea ever since I first read about this unique island in Wallace's marvelous book, The Malay Archipelago, when I was just a kid. My fascination with New Guinea led to my passion for the birdlife there, especially my love for the Birds of Paradise, and the lories and other parrot species. I had always secretly dreamt of visiting this…

I've always enjoyed David Attenborough's nature programs and films when I've managed to see them on TV and now, thanks to several of my readers, I've been able to view nearly everything that Attenborough has available on DVD. But after watching the wonderful collection of films included in Attenborough in Paradise and Other Personal Adventures (BBC Worldwide; 2007), I have been transformed from a pleased watcher into an unabashed and enthusiastic admirer.

As I've mentioned a few times already, my life's passion is the birds of the South Pacific, particularly the Loriinae, which are parrots commonly known as the lories and lorikeets. I study them professionally and I have lived with them and bred them for most of my life. So it was exciting to me when I…
