Supply, demand, extinction

Back in the 90s, Ivan Lozano Ortega was in charge of Bogota's wildlife rescue center. And he kept getting calls from the airport to come deal with... frogs. Hundreds of brightly colored, poisonous frogs.

Ivan had stumbled upon the poisonous frog black market. Tens of thousands of frogs were being poached out of the Colombian rainforest and sold to collectors all around the world by smugglers. And it put these endangered frogs at risk of going extinct.

Today on the show, how Ivan tried to put an end to the poison frog black market, by breeding and selling frogs legally. And he learns that it's not so easy to get a frog out of hot water.

The Extinction Trials by S.M. Wilson


Stormchaser is a teen who lives in a world ravaged by hunger and disease. Food is scarce, and an illness that starts with the blistering and peeling of one's skin soon leads to death.

In her world, a few dinosaurs still exist. Stormchaser has befriended a plesiosaur she's named Milo. This is a secret she must guard closely because dinosaurs are universally hated.

When the Trials are announced, Stormchaser enters on a whim; she doesn't have a family, doesn't have anyone dying from the plague like the others.

The contest is a deadly one: enter the area of the world known as Piloria, where the dinosaurs are abundant, and retrieve as many dinosaur eggs as possible. The winner will receive health care and food, two things essential in order to survive their daily nightmare.

She's joined on the Trials by Lincoln and Leif, two boys with a lot on the line. As the competition heats up, they must learn to trust each other if they're going to avoid being eaten alive. But as Stormchaser soon learns, you can't really trust anyone in the Extinction Trials and what she finds hiding under the surface of Piloria will change her life forever.

The Extinction Trials is a super fast action adventure that anyone looking for a strong female hero will love. It's got elements of The Hunger Games without a doubt, and that's a good thing because it means it will make my job as a School Librarian all the easier when I promote this book in the coming weeks. And promote it I shall, because it's got some great scenes, fully realised characters and a ton of action. Highly recommended, can't wait for the sequel!

Eutrophication led to fish extinctions in Alps

Nutrient pollution and resulting eutrophication has caused a rapid loss of whitefish species from lakes in the European Alps, according to a new genetic and ecological study that sheds light on how these fish became extinct in Swiss lakes.

Cost of reducing species extinction threats calculated

Reducing the extinction risk to all threatened bird species by at least one category on the IUCN Red List by 2020 would cost US$0.875 - 1.23 billion (???0.671-0.94) per year, according to a recent study.

Vertebrate population losses and declines: Earth’s ongoing mass extinction may be more severe than previously estimated

A new study suggests that Earth’s ongoing mass extinction episode is more severe than generally perceived. Rather than focusing on the complete extinction of entire species, researchers analysed the losses and declines of populations in a sample of 27 600 vertebrate species. Population declines and losses are often a prelude to species extinctions. Researchers also conducted a more in-depth analysis of population losses between 1900–2015 in 177 mammal species. The results reveal that rates of population loss and decline in vertebrates are extremely high, even in common “species of low concern”. The data indicates that, in addition to significant species extinction rates, the Earth is experiencing a huge episode of population decline and loss, which will have a significant effect on ecosystem functioning and services. The researchers warn that the window for effective action is closing rapidly and emphasise the need for an urgent response.
