It’s a little difficult to keep up with individual blog posts for every paper I read for #365papers, so I’m just summarizing for one month.

Reading, Reading, Science Reading – #365 papers – June 2017
It’s a little difficult to keep up with individual blog posts for every paper I read for #365papers, for for the next three months you can expect one summary post per month, just like this one…

Does Anyone Really Know How Many Kinds of Birds There Are? – #365papers – 2017 – 151
#365papers for May 31, 2017
What’s it about?
When discussing species diversity, especially in terms of conservation efforts, it’s important to have a good definition of ‘species.’ Here, the authors show that depending on how you define a species, there may be twice as many kinds of birds as we usually think.Continue reading “Does Anyone Really Know How Many Kinds of Birds There Are? – #365papers – 2017 – 151”
How Aluminum in Zircon Can Tell Us What Happened Billions of Years Ago – #365papers – 2017 – 150
#365papers for May 30, 2017
What’s it about?
Zircon is a mineral that forms in igneous rocks. As the rocks erode away, the zircons often survive and can be mixed into younger rocks, including new igneous rocks. Here, the authors use the concentration of aluminum in the zircons to determine the type of igneous rock the zircon originally formed in.Continue reading “How Aluminum in Zircon Can Tell Us What Happened Billions of Years Ago – #365papers – 2017 – 150”
The Magnetic Field and Aurorae of Jupiter – #365papers – 2017 – 149
#365papers for May 28, 2017
What’s it about?
With the instrumentation on the Juno spacecraft, scientists can now measure the strength and shape of the magnetic field around Jupiter and explore the planet’s aurorae (like our Aurora Borealis).Continue reading “The Magnetic Field and Aurorae of Jupiter – #365papers – 2017 – 149”
Peeking Under Jupiter’s Clouds – #365papers – 2017 – 148
#365papers for May 28, 2017
What’s it about?
We finally have a spacecraft close enough to Jupiter that we can take photos of the planet’s poles and better understand what is happening below the cloud tops.

Calcium Can Tell Us About Ancient Ecosystem Structure – #365papers – 2017 – 147
#365papers for May 27, 2017
What’s it about?
The variations of the amounts of stable isotopes (that is non-radioactive) found in rocks and fossils can be used to help us understand patterns of weather, of vegetation, and of who’s eating whom in modern and fossil rocks, bones, teeth, and shells. Most of the time carbon, oxygen, and nitrogen are used for this.
The authors here show that calcium isotopes can be used to understand tropic level (where organisms are on the food chain) in modern and fossil animals. Their work shows that large marine reptiles likely went extinct at the end of the Permian Period because they all lived at the same trophic level. There was some sort of ecological change that eradicated their food supply and the marine reptiles could not recover.Continue reading “Calcium Can Tell Us About Ancient Ecosystem Structure – #365papers – 2017 – 147”
Extinction in the Permian – #365papers – 2017 – 146
#365papers for May 26, 2017
Lucas, 2017, Permian tetrapod extinction events: Earth-Science Reviews, v. 170, p. 31-60.
What’s it about?
The Permian ended with the largest marine extinction ever to strike the Earth, with 95% of species going extinct. This paper discusses life on land, specifically tetrapods (amphibians and reptiles at that time) and how they went extinct.Continue reading “Extinction in the Permian – #365papers – 2017 – 146”
Ann Hinga. Phone Call for Ann Hinga – #365papers – 2017 – 145
#365papers for May 25, 2017
What’s it about?
There’s a family of birds called the Anhingidae, which includes anhingas and darters. This is a description of a new fossil darter from India.Continue reading “Ann Hinga. Phone Call for Ann Hinga – #365papers – 2017 – 145”
Getting Mountains to Move – #365papers – 2017 – 144
#365papers for May 24, 2017
What’s it about?
The Hart Mountain slide is famous (in geology) for being a land slide that covers at least 3500 km3 and may have moved as far as 85 km. How do you get something that big started? This paper shows that the emplacement of an igneous body below what became the slide may have helped trigger the movement.Continue reading “Getting Mountains to Move – #365papers – 2017 – 144”
