It is difficult to get around jungles without paths, so we are very fortunate to have two experienced trailcutters with us. Mani and Uwawa, both Amerindians from southwestern Suriname, have been busy blazing and marking several kilometers of trails with machetes that they repeatedly file to a razor’s edge throughout the day.

Each night after dinner, we meet as a group and map out where we need to open or extend our nascent trail system and the best way to do it. Without Mani and Uwawa, we would simply not be able get our science done.

Today’s agenda was to finish opening a trail to a river a few kilometers from our camp, Geijskes Creek. The entire morning was rather misty as clouds hovered over the plateau, which provided a rather dramatic backdrop when we finally broke into the Geijskes gorge.

Stained by plant tannins, the water is a dark tea color. The creek is strewn with giant sandstone boulders (many the size of cars) that have eroded from the sides of the gorge. Just a few steps downstream, the creek leaps off the plateau’s rim in a waterfall more than 500 feet high.

As the sun starts to break through the lifting clouds, we get to work sampling the creek for aquatic beetles. We get some exciting things on the wet sandstone walls that are likely to be new species, but they are too small to know for sure. We’ll have to get them back to the lab.

The most logistically challenging day of the trip arrived: moving camp to the summit of Tafelberg. The weather cooperated beautifully and we were greeted with a clear, calm morning. Rain or even heavy clouds would have meant the helicopter would have been grounded. The day before, we had flown in a small bush plane to a deserted airstrip near about 20 kilometers from the base of Tafelberg, and we used this as our staging area.

First, we had to weigh all our food and gear and separate it into piles of roughly 400 pounds. Each pile is assembled into a “package” to be slung to the summit by a net hanging from below the helicopter.

Next, we had to locate a suitable landing site on the mountain. Two other members of the team and I got in the helicopter and set out to take a look. There had been an area cleared many years ago by previous expeditions, but it has not been used in quite a while. As we assumed, it had become overgrown. We located a small pocket of open savannah nearby where we could be dropped off safely, then hiked back to the original landing site and cleared it with machetes.

Over the next two hours, the rest of our team and gear were ferried up, and we established our basecamp at a nearby creek.

research

The first scientific expedition to Tafelberg took place exactly 69 years ago this month. Led by legendary botanist Bassett Maguire, the 1944 expedition took more than four months. Needless to say, the logistics of his expedition were a bit different than ours.

Using a small group of canoes powered only by paddles and long poles, he traveled upriver through numerous rapids and overland detours from Paramaribo up the Coppename River and its tributaries. With the help and permission of the local villages he encountered, he set out overland when the rivers became impassable.

supply list

After 23 days of cutting trails with nothing but a compass for navigation, they reached the foot of Tafelberg. Did I mention they had more than 3 tons of gear that had to be hauled every step of the way? And that does not include additional food and supplies that were parachuted to them in the jungle from military planes both along the way and while on the summit.

Fast forward to 2013, and the travel that took his party weeks will take us less than an hour by helicopter. Correspondingly, we are working hard to ensure that our gear (and ourselves…) will “make weight”, as how much we can transport per helicopter run is extremely limited.

If you are curious about just exactly what such an ambitious 1944 expedition took to the field, here is list from a report on the expedition published by Maguire in 1945:

On a completely separate note, we collected our first specimens today. Taking a break from gearing up here in Paramaribo, Devin browsed the central market here for interesting fish, and picked up some freshly caught individuals to prepare as museum specimens.

Suriname landscape

And we’re off! My postdoc Devin Bloom and I just landed in Paramaribo, the capital city of Suriname. From here, we’ll make final preparations for our ultimate destination, Tafelberg (“table mountain” in Dutch). Although not the tallest peak in Suriname (that honor goes to the nearby Juliana Top), it is special because it is the only tepui in the country and the eastern most on the continent.

Tepuis are fortress-like sandstone mesas that are found in this region of South America. Formed largely by erosion of the surrounding sediments rather than uplift or volcanism, these ancient sentries tower over the surrounding jungles, with some reaching 3000 meters in elevation. Roraima, perhaps the most famous tepui, inspired the “The Lost World” by Arthur Conan Doyle and the landscapes in the movie “Up”. The world’s tallest waterfall, Angel Falls, plunges off Ayuan tepui in Venezeula. Although dinosaurs have yet to be found on their summits, tepuis are host to a spectacular array of endemic plants and animals. Many of these may be ancient relicts, representing real examples of Doyle’s undiscovered world.

Compared to more notable tepuis, Tafelberg is small and lonely. It rises to a relatively modest 1000 meters, and is set hundreds of kilometers east of its nearest geological kin. This has led to questions about whether Tafelberg’s flora and fauna share any link with other tepuis, and if so, to what extent?

Soon, the final members of our group from the New York Botanical Garden will arrive, and on August 12, our team will be dropped off at a remote grassy airstrip near the mountain’s base. From there, we will be lifted to the summit of Tafelberg by helicopter to conduct our survey. Until then, we will be finalizing the logistical and supplying details, as well as attending an international congress on the biodiversity of the Guiana Shield.

Andrew Short is a National Geographic Grantee and assistant professor of Ecology & Evolutionary Biology at the University of Kansas. An entomologist by training and at heart, Short is currently in Suriname, South America searching for aquatic insects to study patterns of freshwater biodiversity that will inform both science and conservation. 

Having climbed up through a layer of misting clouds, we reached the summit of Voltzberg just in time to see the day break over the surrounding rainforest. Sitting at the northern edge of the Central Suriname Nature Reserve (CSNR), Voltzberg is one of many imposing granite domes that pepper this ancient South American landscape. A massive swath of tropical wilderness twice the size of my home state of Delaware, the CSNR is almost entirely unpopulated and only accessible by canoe and bushplane.

While taking in the vastness of the landscape was a welcome break from our fieldwork routine that morning last July, my students and I had work to do: documenting the aquatic insects that live in the streams, waterfalls, and forest pools that surrounded us. Our research here, done in collaboration with the National Zoological Collection of Suriname, has uncovered dozens of new species and we’re only just gotten started. These inventories help us approach a number of bigger questions: How similar is this patch of forest to one 50 miles away? What are the ecological limits of these species, and what would happen if the environment changed? Can these insects help us monitor water quality?

We’re making final preparations for our return to Suriname (and CSNR) next week. This time, our target is more ambitious: Tafelberg — an isolated table mountain in the center of the reserve. Stay tuned for updates as our expedition gets underway!

Coming from South Korea and this being my first South American trip, I expected to see many scary animals such as alligators and snakes. I did see several snakes and I will never forget the shape of the green viper which surprised and jumped away from me as I jumped the other way. I also to expected to experience the type of “jungle” where we would use machetes to hack our way through, like Kungfu boys. But in a primary rainforest, it is actually quite dark, with very impressive massive trees that form a canopy, where you might expect to see dinosaurs. The jungle I expected was only along the rivers or in disturbed areas where all the plants were racing to the sun. As I expected, Neotropical rainforests present an endless learning opportunity for me.
 
A brief stop in Lima was necessary to collect the important export permit, which allows us to take specimens out of the country. A Friday night in a big city is like in any other: everyone relaxing, very friendly, smiling, readying for a late night at the start of the weekend. We took the chance to enjoy Peru’s famous cuisine in a nice restaurant in the Kennedy Park area, near the beautiful church, Iglesia de la Virgen Milagrosa, where we recapped the events of our trip.
 
Then we returned to the airport, with a precious cargo of specimens to remind us of every moment of this brief but productive expedition.
 
It is unbelievable that our most distinct memory of the Amazon is of the cold, which we will tell others, with minimal exaggeration. After returning home, we learned that Peru’s government declared a State of Emergency because of the extreme cold. \

Last night was our final night at the research station at the base of Voltzberg. After breakfast, we packed our hammocks and made a pile of the food and gear the porters were going to carry. The porters arrived, packed, and started back to the boat and we followed about 15 minutes later. The whole hike took us a little under two hours which beat our time on the hike in by about thirty minutes. My sweat-soaked shirt felt like I had just taken it out of the washing machine and I couldn’t wait until we got back to Foengoe Island where a cold shower was calling my name.

Unfortunately, a shower would have to wait a while longer. Upon our arrival, the manager informed us that the water pump had broken, so we would have to get any water we needed from the river. I resigned myself to the fact there was no running water, so I hopped into the river for a much needed bath. It was glorious to scrub off three days’ worth of sweat and I came out feeling much better.

Timo Förster, an undergraduate from the University of Greiswald, Germany, is conducting a research internship with me, funded by the German Academic Exchange Service (DAAD). We developed a project to study the insect communities that develop in small pools of water that plants retain (phytotelmata). Pitcher plants may be the most familiar and best studied phytotelmata communities. These pools may form in flowers, seeds, leaves, and damaged stems.  Their communities tend to be dominated by insects, especially beetles.  In 2010, KU undergraduates Joe, Riley and Tom studied such communities in two Zingiberales plants at the Los Amigos Biological Station, Peru; our manuscript is going through the review process for publication. Zingiberales are gorgeous plants and make our fieldwork more special.

I conducted fieldwork with Timo in Peru during Oct 2012 and he has stayed in the field collecting data and specimens on these unusual insect-plant interactions.   Such a lengthy field stay and enormous specimen collections will require years of study and will yield many manuscripts. I am still immersed in the fieldwork because of Timo’s weekly emails reporting on our traps, which plants are flowering, and what surprises he uncovers.  His most recent post does not concern insects, but it is quite thrilling:

“We were walking on trail 8 today (Adrian, Nicole, another researcher, and me).  Suddenly Adrian, who was walking in the front, made signs to hide behind a tree. Suddenly a big group (perhaps 20-30 animals) of white-lipped peccaries came across and we were directly in the middle of their group, as we were hiding behind a tree. About 10 seconds later, we saw a huge yellow cat walking silently only about 5 meters behind the peccaries. The Jaguar was stalking them and was walking so close to us that we could almost touch it (less than 2 meters distance). We saw the cat for about 15 seconds, until it saw us and got scared and fled. All of the time, I was absolutely stunned. After that encounter we made a big party on the mountain. That was my first jaguar and it was one of the most impressive things I saw in the wild so far.”

After many months in the field, I can’t imagine a more precious birthday gift for Timo, turning 23 today!  We are fortunate to access such high quality habitat at Villa Carmen.  I hope my June 2013 field course with KU students will return with equally precious sightings and memories.

Luis Figueroa in our visitor’s cubicle

In my academic calendar, January is usually preoccupied with completing annual evaluations and submitting reports, and grant applications to the U.S. National Science Foundation (NSF). Our Entomology Division was uncommonly busy with several scientists travelling here to study parts of our Hymenoptera, Hemiptera, and Coleoptera collections. 

Mr. Luis Figueroa, a colleague from San Marcos University Museum, Lima, Peru spent a month here studying the scarab beetles that I and my team have collected over several years from Peru. Luis identified many specimens and even found a potentially new species that he and collaborators will study further and perhaps describe as new to science. It is exciting when collections for my own research can benefit other colleagues’ work! 

Dr. Paul Tinerella of the University of Minnesota-St. Paul (http://www.nepomorpha.org/), his doctoral student Gretchen Wilbrandt, and one undergraduate REU-supported researcher, Ms. Jamee Snyder (Fig. 1) visited us to examine our famous Hemiptera (true bugs) collection. Even though we have no active Hemiptera researcher on staff now and this part of the collection is not growing as fast as other taxa, our collection remains a valuable resource to the international community. We are one of 34 museums collaborating in the NSF-supported project http://tcn.amnh.org/, led by Dr. Toby Schuh at the American Museum of Natural History, to digitize and recurate North American Hemiptera specimens and make data available online.
