Small rattles, big personalities

In the dark recesses of Aronoff laboratory, many are surprised to know that our lab has an entire room filled with rattlesnakes. In fact, most visitors don't believe us until we show them. Behind a plain, gray door lives a group of dusky pigmy rattlesnakes (Sistrurus miliarius barbouri). This group of animals has been one of the main sources of data for our lab's efforts in studying pit viper venom and how it relates to these animals diets and behavior. This work is currently being done by our principal investigator, Dr. Lisle Gibbs, and current PhD student Sarah Smiley. 

Right now, one of our undergraduate students (Hardy Kern) is finishing a project examining how these snakes, which have been eating the same type of food for months (either mice or frogs), differ in their interest in other food items. Since some of the snakes were born in the lab, the question is pretty simple: do these animals prefer the only food they've ever known or do they have a preference? I'm sure Hardy will come by at some point to write about his project here, but until then I thought I'd share some photos of the pigmy rattlesnakes that we took as part of Hardy's graduation gift from the grad students. 

The photos show these venomous snakes as we see them: beautiful, gentle, and curious animals.



























If seeing snakes in their natural habitat is more your thing, here are some photos of pigmy rattlesnakes we found last summer during a lab trip to Florida:
































Wherever you see one, these reclusive snakes are always a treat.

A research lab that herps together, works together

Back in August before the semester began, a good portion of the Gibbs lab headed down to Florida for a week of science and reptiles/amphibians. We were visiting some colleagues/collaborators at Florida State University as well as helping Sarah Smiley catch pigmy rattlesnakes for her thesis research.

Believe it or not, I've just recently downloaded the photos from my camera. Here are some of the interesting things we did and interesting creatures we found:

I almost ordered two slices because I didn't believe that they were "as big as your head".
David and Lisle appreciating the alligators
Sarah took us swimming at Wakulla Springs. We were all brave enough to high dive. 
There I was, expecting a honky-tonk. What a disappointment.
A lifer for me: Pig Frog (Lithobates Grylio)

A handsome juvenile Cottonmouth (Agkistrodon piscivorus)



Matt demonstrating the art form of laying out "rock snakes" to trick other cars searching for snakes at night. Classic.
The snake we were after: The Pigmy Rattlesnake (Sistrurus miliarius)
Sarah studies how these snakes' venom is locally adapted to their prey

Pigmy is a good descriptor. Here are four adult snakes at the bottom of a 5 gallon bucket.
Another lifer for me: Little Grass Frog (Pseudacris ocularis). I thought the first one I saw was an insect jumping through the grass.
Sarah gets the royal treatment during the half of the year she spends in Florida at Stetson University.
It was hot and humid, but we found snakes. Left to right: David Salazar, Sarah Smiley, Terry Farrell, Lisle Gibbs, Matt Holding, Rob Denton

Field Herpetology at The Southwest Research Station (Part 3)

I had a fantastic time teaching at the Southwestern Research Station's Field Herpetology course this year. We returned to Ohio on Wednesday and definitely needed a couple of days to recover from eight straight days of hiking, teaching, and chasing after reptiles/amphibians.

I had a few more pictures of animals and class activities, so we needed a part three to finish things up.

Last beautiful day at the research station:

The students had an awesome time catching Sonora Mud Turtles (Kinosternon sonoriense) with Dr. Justin Congdon, Professor Emeritus at the University of Georgia. He's about the coolest guy you could meet.


I didn't eat it. They smell bad.

During a pit stop to meet Justin, we found two Ornate Box Turtles (Terrapene ornata):
Bad photo because I was on the phone due to my credit card information being stolen. Thanks criminals.

In between catching mud turtles, we spotted this really beautiful Greater Short-horned Lizard (Phrynosoma hernandesi):

Very photogenic.

If you take the field herpetology course, the instructors promise to wear you out and then laugh while we take photos of you asleep.


One of the most fun labs is the sprint speed lab, where students race lizards with different locomotion strategies and compare.



Sonoran Whipsnake (Coluber bilineatus):

 Chiricahua Leopard Frog after being released:

Finally, here is Matt at airport security during the trip back home to Ohio. He is a guy who is used to answering 100 questions from TSA agents regarding the safety of snake tongs (the orange and silver device under inspection in this photo):

I can't wait 'til next year. We are home for just a few days before embarking on the first annual Gibbs lab field trip to Florida, where we will be assisting labmate Sarah Smiley in catching pigmy rattlesnakes for her research.

Field Herpetology at the Southwest Research Station (Part 2)

More photos from the 2013 Field Herpetology course!

The first female Leopard Lizard (Gambelia wislizenii) I have ever seen hold still:


















Herpetologist photobomb:























Round-tailed Horned Lizard (Phrynosoma modestum):




Twin-spotted Rattlesnake (Crotalus priceii):
Huge male!
Think rattlensakes are mean? Look at this individual hiding his head.

Bad lighting, but a beautiful snake.

My very first Bunchgrass Lizard (Sceloporus slevini). A tough find all the way up the mountains:


Here is some of the variation in Long-nosed Snakes (Rhinocheilus lecontei):

Field Herpetology at the Southwest Research Station (Part 1)

We are three days through the 2013 Field Herpetology course at the Southwest Research Station. Whew, what a whirlwind this course is for the second year in a row. We have students from all over the country: college students, retired doctors, government contractors, and environmental consultants. 

I've been busy tweeting some of our activities, but need a place to show you some of the photos of the class at work and the animals we are finding. So here ya go.

A handsome Greater Earless Lizard (Cophosaurus texanus):

Dr. Carol Simon gives a seminar on the natural history of the Chiricahua Mountains:

My main man Dr. Steve Mullin describing the sexual differences between kingsnakes:


Here is a group of endangered Chiricahua Leopard Frogs (Lithobates chiricaheunsis):

Here is Matt Holding demonstrating to the field herpetology students and local residents how scientists safely transport and restrain venomous snakes:


Dr. Emily Taylor and Matt Holding implant a radio transmitter in a Black-tailed Rattlesnake (Crotalus molossus):

My favorite rattlesnake: The Rock Rattlesnake (C. lepidus)!


A really nice find from night driving was a pair of Desert Kingsnakes (Lampropeltis splendida). She was no doubt cruising around looking for a nice rattlesnake meal. 

One of our first field trips was to Granite Gap, an area in Arizona know for having both a beautiful community of cactus and a thriving population of Gila Monsters (Heloderma suspectum).


And here is the star of the show. Worth all of the heavy hiking, for sure.
