Dominican naturalist, photographer, and professional guide Miguel Landestoy visited KU Herpetology for several days in early June to view specimens and records from the late Albert Schwartz. Miguel is working to track down some of Schwartz's most unusual discoveries and came to KU primarily to familiarize himself with a few species that are particularly well-represented in Schwartz's material, but rare elsewhere. Check out Miguel's photos on Flickr.
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.
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

Lima (sea level) to Cusco (3400 m) to Wayqecha (3000 m)…..Quite a change in one day! We were off and running in Cusco with quick stops at the grocery and hardware store for last supplies before heading to more remote areas. Our drive on the winding Manu Highway (a gravel road) to the Wayqecha Biological Station was super dusty. It turns out that it has not rained in these cloud forests for over three weeks. A short dry season usually occurs in August-September so this drought was unusual. The clouds have been coming in over the Amazon Basin, but dropping their moisture at lower elevations. As in Kansas, a dry season means reduced insect activity. Our first 3-hr trail walk today through cloud forests turned into a botany exercise since I point out the forest structure, physical characteristics, and plant composition. We go slowly, testing our fitness at this elevation; the students are breaking in their new clothing and shoes. I aim to introduce the forest structure and its plants, to learn some familiar plant families and some rare/unusual ones—Orchids and ferns, mosses and lichens, Proteceace, Bamboo, Solanaceae, Rubiaceae, Selaginellas, and tree ferns. The filmy ferns (Hymenophyllaceae) are just one cell thick, transparent and rely on damp conditions; well, they were crispy ferns, dried and dormant, awaiting rain. We got far out on the trail, when the clouds rolled in and poured! The intermittent canopy slows the drips, but we were still quite soaked by the time we returned to the station buildings. We might be huffing and puffing on the first walks at this elevation, but we had a glorious morning of botanising. And the filmy ferns are happy again.
On day two of our adventure in Lima, Peru, we were exposed to the fascinating history of various different cultural practices performed by a variety of Peruvian nations. One of the most intriguing of these practices that we learned about is cranial trepanation, in which the skull of the human being is intentionally deformed. This process is performed during early infancy when the skull is the most pliable.
While visiting the Museo Nacional Arqueología, Antropología y Historia de Perú in Lima, we learned about this practice of the pre-Incan Paracas nation (750 BC-100 AD). The museum displays skulls that have undergone three different types of cranial trepanation. These variations employ a variety of methods and result in a different head shape. One type, called tabulate modeling, utilizes a wood panel placed at the nape of the neck and projected upwards; a rope keeps the wood panel steady. It results in an elongated skull that extends upwards. The second type of modeling we saw is trepanning, which also produces an elongated skull. The third type is bilobular results in a heart-shaped, rounded skull that is produced by a very specific method of wrapping cloth.
Researchers strongly believe that this process was used in the Paracas culture as a means to delineate the social status of an individual. However, very little else is known, such as what does each separate shape say about the individual’s specific status? Our tour guide Fernando Benaducci Otayza (who was INCREDIBLY knowledgeable and passionate about Peruvian history!) had the opinion that head binding must have been performed on people of lower classes because it is an incredibly painful process (so, punishing?) with various neurological repercussions. I am encouraged to think the opposite, though simply because the process of head-binding requires a lot of planning and attention for an extended period of time; it makes more sense to me that this time could only be afforded to those of a higher social standing. After all, “beauty is pain” is a cultural saying that has reached just about every corner of the world.
However, the intrigue isn’t so much in whether or not I am “right” or the tour guide is “right”, it’s in the mere fact that there is an elaborate cultural process that dramatically changed the lives of the Paracas people and continues to baffle us to this day. -Sarah
My biggest surprise in Lima is its architecture. Lima is a city of 9 million people (as big as Chicago). As you can imagine, this means buildings are narrow and tall, but very close together. The layout is very beautiful, with many bright colors and a variety of modern, traditional, colonial, and Peruvian styles.
This combination is spectacular in Lima’s downtown. The cathedrals are my favorite buildings, even though I am not very religious. Peru’s population is around 86% catholic; therefore, churches are extremely important here. The extravagant churches reflect this. Not only the outside of the churches are beautiful, but the inside as well.
Our group was very fortunate to climb into one of the biggest cathedral towers at St. Dominic’s Monastery. Six stories of stairs led the top of the tower; each level had a different display about the history of the church. These displays consisted of a level with pictures, a photo booth, bells, tiles, and pews. My personal favorite was the penultimate story had different giant bells hanging from the ceiling. When we finally reached the top of the tower you could see miles and miles away over the city in every direction – absolutely breathtaking!
Today outside of the archeological museum [National Museum of the Archaeology, Anthropology, and History], Paige and I witnessed a small but festive parade. At first I assumed they were celebrating a holiday we didn’t know of, but as we got closer, we realized it was a parade for a Catholic elementary school’s “Family Olympics”.
Each grade came marching down the street in different brightly colored sections, with their parents beating drums, blowing whistles, and throwing confetti into the air, chanting when they reached the middle of the street where the nuns were watching. This concept of the family Olympics reminded me of an event my elementary school did with our families called the jog-a-thon.
I found it interesting that they held a parade for something as simple as a school’s family event. People who were just out on walks with their dogs even stopped to watch the children go by; there were people on stilts and someone dressed as Elmo showed up too. I really enjoyed watching the children and their parents marching down the street and chanting, playing in unison, and having a great time. I would have loved a school celebration like that when I was in elementary school.
