Where The Deer & The Antelope Play

Just a short video we took of two adorable antelope that were running and playing in the foothills during one of our trips back down from Cloud Camping...

They are very beautiful creatures and usually pretty friendly, curious and willing to come up close & check you out. These guys were as relaxed as can be which may have had something to do with it being the start of Elk season, eh?

This video and this post are about pronghorn antelope in the USA.

Family tree of all snakes and lizards

Biologist Maps the Family Tree of All Known Snake and Lizard Groups

A George Washington University biologist and a team of researchers have created the first large-scale evolutionary family tree for every snake and lizard around the globe.

The findings were recently published in the journal BMC Evolutionary Biology. Alex Pyron, the Robert F. Griggs Assistant Professor of Biology in GW’s Columbian College of Arts and Sciences, along with researchers from the City University of New York and Arizona State University, detail the cataloging of 4,161 species of snakes and lizards, or squamates.

Squamates include all lizards and snakes found throughout the globe, including around 9,500 species on every continent except Antarctica, and found in most oceans,” said Dr. Pyron. “This is everything from cobras to garter snakes to tiny geckos to the Komodo Dragon to the Gila Monster. They range from tiny threadsnakes that can curl up on a dime to 10 feet monitor lizards and 30 foot pythons. They eat everything from ants to wildebeest.”

The evolutionary family tree, or phylogeny, includes all families and subfamilies and most genus and species groups, said Dr. Pyron. While there are gaps on some branches of the tree, the structure of the tree goes a long way toward fully mapping every genus and species group.

“It’s like building an incomplete family tree for your family, but with half of the ‘children’ sampled. You’re in it, but not your brother, one of your cousins is, but not another. However, because it’s so complete, we know where the missing relatives go because there’s no longer as much mystery as to how the missing species, or cousins, are related, with a few notable exceptions for some remaining species.

“This is also a community effort. We sequenced hundreds of these species ourselves but took thousands more from public databases, building on the work of others.”

Understanding how various snakes and lizards are connected to each other fills a major gap in knowledge, said Dr. Pyron, because before this, there were no single reference for how all lizards and snakes were related or what their classification was.

“A phylogeny and taxonomy is fundamental for all fields of biology that use lizards and snakes, to understand how to classify the species being studied, to interpret biological patterns in terms of relatedness, and even at a more basic level, to count how many species are in an area, for example, for conservation management purposes.”

This project has been in the works since 2008 with the last five years being the most intense. It was funded by the National Science Foundation Postdoctoral Research Fellowship in Biological Informatics.

The researchers used DNA sequencing technology to genotype, or identify, the DNA of thousands of lizards and snakes.

“We have laid down the structure of squamate relationships and yet this is still the beginning,” said Dr. Pyron. “As hundreds of new species are described every year from around the glove, this estimate of the squamate tree of life shows us what we do know, and more importantly, what we don’t know, and will hopefully spur even more research on the amazing diversity of lizards and snakes.”

Cicada invasion in the USA


This video is called Invasion East Coast! Billions of Cicadas Will Swarm the Region after 17 Years Underground!

From Wildlife Extra:

Vast cicada swarm due in USA

April 2013. Residents of north-eastern USA will soon observe an event not seen since 1996: The coming mass emergence of the Brood II cicadas.

1.5 million per acre!

After spending 17 years living underground as nymphs, these large, winged insects will emerge to live out their short adult lives above ground. As many as 1.5 million cicadas can live per acre, and they are noisy too, they will certainly be heard: Cicadas have a unique call that can reach a whopping 90 decibels.

As alarming as this sounds, cicadas are actually quite harmless. In fact, they have positive effects on plants and provide food for many different animals, including birds, mammals, reptiles, even other insects.

Brood 2 cicadas appear every 17 years across New York, Washington, D.C., Connecticut, Maryland, North Carolina, New Jersey, Pennsylvania, and Virginia. They measure just 1½ inches long and live for just 2 weeks. They live underground for 17 years, feeding on the juices of tree roots, before emerging to mate once every 17 years (That’s a long wait. Ed.). They live above ground for just 2 weeks before they die.

There are several broods that appear once every 13 or 17 years in a very unusual life cycle, and when they overlap, it must be like the biblical plague.

The Brood II Emergence Has Begun

It has begun!

Over on the Entomology-Cicadidae cicada group a gentleman named Tommy Joseph has posted photos of periodical cicadas which have emerged this week in Greensboro, North Carolina This makes sense as North Carolina is the southern-most state with a Brood II population, and southern states warm up before northern states.

There are also plenty of sightings (mostly nymphs, but some adults) on the Magicicada.org map. Don’t forget to post your sighting there.
