One characteristic of rain and cloud forests are the diversity of epiphytes, life forms growing on top of other life forms. ‘Aerial garden’ is used nowadays to refer to roof-top gardens sprouting on little-used spaces of high-rise buildings around the world. Classically, it has referred to the plethora of plants that assemble on the trunks and limbs of rainforest trees. ‘Aerial aquaria’ are the bromeliads that accumulate rainwater, soil and animal communities at the base of the rosette of leaves. Canopy walkways, aerial traps, open-air gondolas, and zip-lining are frequently being constructed for scientists and nature lovers to learn about these hard-to-reach forest layers.
In our daily walks along trails at the Zurqui de Moravia site near San Jose and here in the Monteverde Cloud Forest, we take advantage of fallen trees and broken tree limbs to test out our botany knowledge, add a few more families to our life lists, and poke around for hidden snakes, frogs, and especially insects. I don’t have the heart to peel off the carpet of mosses, filmy ferns, and flowering orchids to find beetles and bugs. Documenting the arthropod community living in the phytotelmata of a bromeliad is destructive sampling – tearing leaves apart and using forceps to spread the soil. Fortunately, this is not the focus of my current research nor permitted by my Costa Rica research permit; thus, I am spared the conflict of attacking these gorgeous bromeliads for cryptic insect treasures.
I visited Monteverde in June 1994, as a student in a field course led by former KU professor, Dr. Michael Greenfield. This was before my own current students here were born! Back then I was enchanted by the forest, its birds awaking me as they began singing from about 4 am, by the clouds drifting in with their misty moisture, and the overwhelming diversity of plants. The old field station inside the reserve was a wooden 2-story construction, with poorly lit rooms and scary showers. My student companions and I then complained of the wet and cold, while enjoying being far from home in this extraordinary forest.
In 1951, 11 American Quaker families migrated to this area in protest of the Korean War. Costa Rica had abolished its army and was an attractive destination. As the community established and grew, developing a low-key farming model, biologists began arriving for research. The reserve was established in 1972 to protect one of the world’s most diverse and virgin forests, with 6 ecological life zones and more than 2500 species of plants.
Today, Monteverde has grown, like Costa Rica, into a super-successful model of nature tourism and conservation. The road, now paved, passes through the towns of Santa Elena and Monteverde. My jaw dropped with the number of shops and hotels. The new field station offers fine dining, its own gift shop, and a small army of workers and guides. The forest is still a wet and cold place and the station still has heart-stopping frigid showers.
It is a remarkable site to view the busloads of school groups and families and their uniformed guides arriving early, even before 7am, paying the entrance fees and heading off on the trails. More wondrous is that over 70,000 visitors come here annually to learn about biology and ecology!
I am Caroline Chaboo, Director of this 2015 program to Costa Rica. Normally, I head to Peru every June with students. However, this year Costa Rica is on the menu due to several factors and opportunities. The University of Costa Rica and the University of Kansas have a long established relationship of collaboration in research, education and visits. This program is supported by KU's Office of International Programs.
In 2014, I expanded one aspect of my Peru research, arthropod communities on Zingiberales plants, and sought a second site for comparative study. Two UCR colleagues, one I met more than 10 years ago, developed a grant proposal which was funded. One UCR collaborator visited KU recently (his first visit to the USA). Our plan is to develop a Central American site and study the diversity (taxonomic and food web relations) of the arthropods that are associated with these distinctive Zingiberales plants (familiar ones are bananas and ginger, but flowers are also sold in shops).
The field course program developed as a way to initiate a joint education program alongside the larger research so we could bring KU and UCR students together, conducting research towards their first scientific publication as they gained exposure to rich tropical habitats and acquired several field skills.
Some KU participants opted to pursue grants for research, which they were awarded. We have met several times to discuss everything, from travel medicine to hiking shoes. I am excited to renew collaborations with the excellent UCR biology faculty and to expose KU students to Costa Rica = "rich coast" = rich biodiversity.

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
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.
Shortly before leaving for Peru, the team visited the Spencer Museum of Art for a art and science discussion with Curators Steve Goddard — a 2011 Peru trip alum — and Casey Messick.
I am Caroline Chaboo, a faculty-curator in the Biodiversity Institute with research interests in biodiversity and leaf beetles. I am the course leader for this field program in Peru and this will be my 8th visit to Peru. Although the group is visiting places I have explored before, the program remains exciting because of our team is different each year. The individual expertise, interests, and perspectives of each individual enhances all our experiences. I am excited for our new adventures together.
Please congratulate Dr. Matthew Gimmel on his acceptance of a 2.5 year European Social Fund postdoctoral fellowship to work on beetle systematics in the lab of Dr. Milada Bocakova, Department of Biology, Palacký University, Olomouc, Czech Republic. Since graduating from Louisiana State University (Dr. Chris Carlton's lab), Matt has worked as my lab manager, helping so much with my Peru project: processing an unbelievable amount of specimens, overseeing undergraduate assistants, helping to mentor undergraduate researchers in their manuscripts. Indeed, his enormous knowledge of beetles, coupled with his generosity, patience, and enthusiasm, has made him a wonderful mentor to all in our unit. Now, we must race to submit our first manuscript together — on Peru beetles, of course - before he departs Kansas for Europe.
The Chaboo lab hosted Sara López from the Ciudad Universitaria (UNAM) and the Departament of Zoology, National Collection of Insects, Mexico City, Mexico. Sara is conducting M.Sc. research on a revision and phylogeny of the genus, Ogdoecosta (Cassidinae: Mesomphaliini). Several cassidine genera have most of their species distributed in Mexico, and Ogdoecosta is one of them. Sara’s phylogenetic matrix will open new research into the biology of this little known group. We had a super time discussing morphology, characters, biology, and combing historical literature for clues of new characters, to understand how important researchers like Spaeth and Boheman defined the genus and species. Good luck to Sara in completing this important new work in Cassidinae and in becoming a badly-needed expert of the Mexican chrysomelid fauna.
