Christmas arrived early this year for people who love animals carrying transmitters around. A new open-access journal called Animal Biotelemetry launched this week, and it promises to bring new tales of mind-blowing bird migrations and seals that study climate change (without exactly having volunteered for the job). Also, sharks.
Published by BioMed Central, the journal will include all kinds of research having to do with biological data gathered by instruments attached to animals. Thi........ Read more »

A team of Virginia Tech researchers has discovered a way to extract large quantities of hydrogen from any plant, a breakthrough that has the potential to bring a low-cost, environmentally friendly fuel source to the world.
“Our new process could help end our dependence on fossil fuels,” said Y.H. Percival Zhang, an associate professor of biological systems engineering in the College of Agriculture and Life Sciences and the College of Engineering. “Hydrogen is one of the most........ Read more »

Lions: just big kitties really! There have been a couple of lion stories in the news in the last week or two, and enough interest in them that I felt compelled to write something. First there was a paper by Craig Packer and many coauthors about lion populations in Africa, their current declines, and the possible role of fencing in protecting them. Then, shortly after, there was a letter in the New York Times by Tanzania's own Director of Wildlife, asking the US government not to list the lion as........ Read more »

The decisions of this chimpanzee living in the Tchimpounga Chimpanzee Sanctuary are affected by his social situation. Photo by Alex Rosati.If you have a choice between a prize that is awesome half the time and totally lame the other half of the time or a mediocre prize that is a sure-thing, which would you choose? Your choice probably depends on your personality somewhat. It may also depend on your needs and your mood. And it can depend on social contexts, like if you’re competing with someone........

We’ve laughed in the past about a “genome of the day” because there are so many projects each week that we want to explore, and it’s hard to keep up.

A fish swims along a sandy lake bottom, carrying one of its babies in its mouth. It approaches the nesting cave of another family of fish. With a furtive "ptooey," it leaves the baby behind for adoption. For certain fish, this seems to be a common scene: giving up your young and taking on others' may be the best way to ensure your offspring grow past snack size.
The fish in question is Neolamprologus caudopunctatus, a type of cichlid (pronounced like a compliment for someone's hat).* Ju........ Read more »

How do you catch a dragon? Do you go looking for a brave knight to send forth on a difficult quest? Or a legendary hunter without fear?
No. You use cameras to capture their image.
To be clear, the dragons we’re talking about here are Komodo dragons (Varanus komodoensis), the largest living lizards, which can be found on some Indonesian islands and can reach a length of 3 meters. Their size, along with the absence of large mammalian carnivores on the islands, makes them apex predators........ Read more »

This week, I found a paper that I’m calling the best of both worlds. Well, for me at least. This paper combines my past (and lingering) interest in island biogeography with a current interest in climate change and carbon storage.If you have been reading my blog long enough then you already know my love of islands. They are just so darn useful. In the past, I have focused on oceanic islands, but lake islands are also really neat. These types of islands typically form when lower lying land........ Read more »

Too many mouths to feed? Just make your babies fight each other to the death! That's a strategy some bird parents have been using since even before The Hunger Games was popular. It means the strongest chicks get stronger while the weakest ones conveniently stop showing up to the table.
One type of bird takes this family drama a step further: after letting the biggest chicks bully their siblings for a while, parents suddenly decide the runts are their favorites and begin beating up ........ Read more »

In Africa people eat monkey meat for the protein it contains.

Over the course of hundreds of millions of years, the combustible, black rock we call coal was formed from the vast peat bogs of flooded forests. For centuries, people have burned lumps of coal for smoky fuel, such that opposition to its pollution had been voiced as early as the fourteenth century. Today, as anti-coal movements emphasize a role in climate change and miners cope with unemployment, a novel, microporous material may challenge objections to coal by cleaning up its carbon emissions....
