We are having a great start with our Friday Herpetology Lunch meetings for the Fall term. Our lunch on Friday, August 29th included 18 individuals representing seven countries (USA, Brazil, India, Malaysia, China/Tibet, Ecuador, Taiwan). Curator Rich Glor discussed how to assist with development of the division's new website and curatorial assistant Matt Buehler shared some examples of problematic specimens recovered during an assessment of the snake collection.
A resident of Lenexa, KS took the photographs above of a lizard on the side of his house in mid-August of 2014. It looks somewhat like a lizard dressed in a spiderman costume. Who can identify the species? Is this a species that has ever been reported in Kansas previously? Is it likely to be a permanent resident of our state?
A friend of KU Herpetology just sent the photos above and noted that the snake in these images "fell off a roof at ocean adventure" in Subic Bay, Luzon, Philippines. Anybody know what species it is? Both photos copyright William Ross from Ocean Adventure, Subic, Luzon.
A friend of KU Herpetology in the Endowment office would like to know if we have any thoughts on the identify of the snake whose shed skin was found by some kids heading into a hole near her garage. The sender notes that while the images are reasonably well-lit and in-focus compared to the photos we usually receive that the basket weave chair may have been included to challenge us. Best guess wins a point in the KU Center for Herpetological Accuracy's Annual herp identification contest.
Undergraduate researcher Catherine Chen recently presented the results of her research at the Summer Undergraduate Research Poster Session in the KU Union. Catherine's work investigated stereotypical display behavior in the lizard Anolis distichus.
On Thursday, July 10th, KU Herpetology curator Rich Glor hosted a field trip by undergraduate students in the Kansas State Summer REU program under the direction of Drs. Bruce Snyder and Ted Morgan. The long-running K State REU program is analagous to KU's own REU program in ecology and evolutionary biology and has seen completion of a range of interesting undergraduate projects and publications, many relating to biodiversity science. The members of the K State proved an impressive and engaged group with plenty of good questions.
Ever since Steve Goddard, KU’s Spencer Art Museum, introduced me to Sunprints during our 2011 field class at the CICRA Biological Station, I have incorporated this art/science activity with subsequent classes. Sun-printing, developed by 19th century artists, uses the sun’s UV rays to make prints of objects on photographic paper. [UC Berkeley sells convenient kits].
After a morning of tough high-elevation hiking and a rich lunch of quinoa soup, we needed a quieter diversion. My kit had 15 sheets, enough for my KU students as well as others conducting research here. Each person collected some leaves and flowers and spent a few minutes designing their layout. Then we got to “printing”, essentially exposing the plate to sun for ~4-6 mins.
The end-product is beautiful and frame-able. Indeed, some appeared in our 2012 Spencer exhibition, http://www.spencerart.ku.edu/exhibitions/39-trails.shtml. This fun art/science exercise opens various discussions, e.g., about sunlight traveling down through forest layers* and leaf morphology**. No winner of our competition was selected since we could not agree on a single most beautiful plate from so many.

During our eight-day stay at the Villa Carmen Biological station, four days were a wash-out. The unusual weather, with rain there and drought here at Wayqecha, is being explained by the locals as probably due to this being an El Niño year. What is a researcher to do with time to sit around? We finally can flesh out our data (digital or notebooks), have time to explore the station’s library, or chat with other visiting researchers. Inevitably, one gets a little desperate for rain to stop falling in the rainforest. The students are glum and I am anxious.
Set-backs crop up: an important piece of equipment borrowed by another researcher is missing; humidity affects one computer; other trap batteries are not charging well on solar panels, so one student must switch project plans; a student gets a minor cut but requires stitches at the local clinic (US$3/3 stitches); and inevitably, two students get the stomach bug. Today was the last collecting day; we took down traps and I sorted the equipment to return to KS and those that will stay for next year’s fieldwork. More bad news – my export permit won’t be ready until Tuesday, after I fly out on Monday night.
Fieldwork isn’t always smooth and I have no choice but to keep calm and carry on. -Caroline Chaboo
Of course, the last day at Villa Carmen is the day the sun shines. It is supposed to be the beginning of the dry season, yet we have had rain everyday. Only two days were dry enough in the afternoons for me to enjoy a sampling period. I had one full day of sampling without rain at the beginning of our stay here, and then there’s today.
Today is packing day, but I was able to sample for a few hours this morning. I am surveying the diversity of orchid bees, Euglossini. Some species are a beautiful metallic color; others are fuzzier and yellow and black striped. This is KU’s 4th season to survey these bees in this corner of the Amazon basin*. The males collect pheromones from volatile compounds, such as eucalyptus. It’s unknown if they do this for mating behavior or another purpose. I apply various scents to cardboard squares, as baits to attract the bees. Once they are distracted by the scent and hanging out at the bait, I net them, document the bee and scent in my field notebook, and retain the tagged specimen for lab study. It is surprising how sophisticated is their eyesight. I swear they see me and hover at the bait, sometimes, staring directly at me. Today, they loved the purple verbena in the garden.
Euglossini, Orchid Bees, are known to pollinate orchids and many other plants. Around here they are also pollinators of the Brazil nut tree, an important indigenous tree. We commonly eat Brazil nuts in party nut mixes. Since there aren’t any orchid bees at Wayqecha, one begs the question, “What pollinates the amazing number of high-Andean orchids?”
In the field, you never know what environmental conditions you’re going to get. It’s one of the things I love about it and one of the things that people, who prefer to work in a lab, hate about it. -Carey Bowen

This past semester, I took a class with a professor who specializes in mercury in the environment. This exposed me to various research projects about mercury in the Long Island Sound, USA . I learned that there are variations in the natural abundance of mercury in the environment and that humans have increased this level via various industrial practices. Connecticut, where I attend college, is a prime area to study the cycling and effects of anthropomorphic mercury in the environment because of this area’s historical contribution to the hat-making industry. In the 1800s and early 1900s, liquid mercury was used to mat fur pelts that were manufactured into fashionable hats. Due to the neurological effects of mercury, the saying “Mad as a hatter” was born.
A large group of professors and students from Duke University Department of Public Health visited Villa Carmen Station this weekend. Their project in medical entomology and environmental toxicology examines gold mining in this part of Peru to see if there is a correlation between the environmental mercury concentration and the mercury concentration in residents’ blood, hair, nails, and food intake. Historically, mercury is a key component in gold mining. The global increase in the price of gold has resulted in a recent escalation of gold mining in this area, and possibly, an increase in the environmental mercury concentration. With these data, the Duke team will compare incidents of malaria (and other diseases) to see if mercury makes individuals more susceptible to infections. Their project is an example of how environmental mercury research is of interest to many different scientists from different disciplines around the world.
