The impact of the border wall on wildlife

Sadly, the people who want the border wall, likely will not care that it will drastically impact wildlife along the border.

But over at Vox, an excellent piece by Eliza Barclay and Sarah Frostenson lays out an amazing argument (and demonstrates visually) how this will impact biodiversity along the border.

Sadly, as this wall becomes a reality (if it becomes a reality) this is not the first or the last time we’ll be having this discussion.

The most important (transitional) fossil you’ve never heard of

I LOVE ME SOME TRANSITIONAL FOSSILS!

But this one is particularly interesting, as it fills a crucial hole in the fossil record and demonstrates how four-limbed creatures became established on land. Found on the Scottish border, it’s called (wait for it…) Tiny.

The Woolly Mammoth’s Last Stand

Woolly mammoths once flourished from northern Europe to Siberia. As the last ice age drew to a close some 10,000 years ago, the mainland population perished, victims of climate change and human hunters.

However, a remote island population survived for 6000 years after the mainland had died off. And from a tooth of a male mammoth, geneticists have now deciphered the reason the population ultimately went extinct.

Read about it in the New York Times.

A Race to Document Rare Plants Before These Cliffs Are Ground to Dust

Not figurative dust. Literal dust. Cambodia’s limestone karsts exist nowhere else and are home to a host of endemic species. These environments are being pulverized for cement and scientists are racing to document all the rare plants before they are gone.

Snails are going extinct

Given that I studied an abundant snail during my PhD (actually, Potamopyrgus antipodarum is invasive throughout most of the world), this headline was alarming to me.

But like many uncharismatic microfauna, snails are declining in record number across a number of different habitats.

Read about it over at Scientific America, and save the snails!

The Pregnant T-rex

It’s often hard to determine the sex of fossils (most of our parts that determine such things are not… fossilizable).

But researchers from North Carolina State University and North Carolina Museum of Natural Sciences found a medullary bone, a kind of tissue found only in female birds that are carrying eggs, or have just finished laying them, in a T-rex fossil from the Cretaceous.

While this is exciting (and you should read about it over at the Washington Post), it may be more exciting as researchers now have a means of identifying sex of dinosaurs. Which allows us to find out more about sex-linked traits in extinct dinosaurs.

An artichoke with legs: the pangolin

c026c5902911ebd8cf6c7c912cca0631Some days I just need a pick me up. While others take to the internet and fine photos of kittens telling them to hang in there, I seek the adorable face of the pangolin._80790888_cape_pangolin_spl624

Also known as the spiny anteater, it is the only mammal wholly covered in scales. They resemble artichokes on legs. Oh and they are beyond adorable.  415e1bec42a96a15e13e0323be919600

However, all 8 species of pangolins are endangered because they have one more distinction: the worlds most trafficked mammal. Their meat has become a delicacy in vietnam, which has rapidly wiped out populations of pangolins across South East Asia.

Read about their plight over at BBC, and for a little Friday pick me up, enjoy these lovely photos of my favorite mammal.
