Illinois IGERT in Panama

About Us

We are first-year Ph.D. students at the University of Illinois, part of the School of Integrated Biology. Thanks to an NSF IGERT program, we are spending our first spring semester learning from and doing research with scientists from the Smithsonian Tropical Research Institute!
Beryl is broadly interested in social insect behavior and the mechanisms underlying social evolution in insects. In Panama, she will be studying a facultatively eusocial sweat bee, Megalopta genalis, to discover the molecular pathways involved in reproductive division of labor among these Halictine bees
Cassie is interested in the evolution of paleograsslands. In Panama, she will be training in paleopalynology (fossilized pollen) with the intent of doing future work in the tropics.
Erin is interested in infectious disease, transmission dynamics, evolution of virulence, and how parasitism influences host behavior to maximize transmission.
Kelsey is interested in human population histories, especially in using ancient DNA to answer questions about Native American migration into North America. In Panama, she will be analyzing dogs from ancient Panamanian settlements.
Lorena is interested in understanding how environmental and climate changes will affect crop growth - specifically, ozone tolerance in corn. In Panama, she is still trying to figure out her project.
Nick is interested in the genetic basis of coloration in birds. In Panama, he will be researching physiological tolerances to different climates in various bird species.
Phred is interested in local adaptations, speciation and biogeography of birds. In Panama, he will be investigating physiological plasticity in tropical birds.
Selina is generally interested in plant-ant interactions, invasion ecology, and restoration ecology. In Panama, she will be investigating the chemical mechanism behind seed choice in ants.
Welcome!

Lorena: Diversity of plants, animals and landscapes during IGERT course

With this post I plan to summarize my IGERT course experience in 40 images.

2)      As scientists we are well aware that we need distractions from our research to keep our sanity. For this reason, researchers at BCI take boat trips to the “Attitude adjustment cove”. This tree could be seen on the way to the cove. It was been dead for more than 100 yrs however many epiphytes live on the trunk which gives the impression that the tree is alive even due is submerge in the water.

3)      As part of Rachel Page’s talk we went with her and a few of her lab members to catch bat. Here a bat feeding from a sugar based solution. This is done because bats have an accelerate metabolism and keeping them without food for too long could put their lives at risk.

10)  A local farmer from the Achiote community explains his growing techniques and all the problems he confronts with different pests. Although he does not have an official degree his more than 30 years of experience in agriculture is enough to master growing techniques for rice, plantain, and corn among other crops.

Kelsey: The Cloud Forest

We spent three nights in what is probably the most magical landscape in Panama: the Cloud Forest at Fortuna. For me, the name just evokes fairytales and ancient kingdoms, ivy-covered towers rising into the sky. Pretty improbable for a real place, right? You would think I would be pretty much over forests at this point, after visiting BCI and walking around Gamboa.

Image

The rolling hills should have clued me in that we were heading to a beautiful place. Fortuna is a high-elevation forest, where the mountain tops reach into the clouds and the heat and humidity of Gamboa is nothing but a memory. It was nice and cool during our stay – highs of 75, with constant cool breezes.

Image

Our gracious host was Dr. Jim Dalling, a professor at Illinois. He spends a lot of time doing research in Fortuna as well, though. Montane forests have tons of tropical diversity, and they aren’t nearly as well-studied as lower-elevation tropical forests. We hiked around a lot of tree plots during our stay. On the first day, we were taken to three different locations:

Palo Seco,

Image

Charro,

Image

and Honda.

Image

Each of these sites has a different soil content, which in turn affects the tree composition of the forest. We did a lot of hiking the first day, but it was nothing compared to El Hornito the next day. What was supposed to be a 3-hour hike ended up being closer to 7…it was a long haul but the views were beautiful. We were hiking through the mist part of the way and the views were just breathtaking!

I would say of all the sites we’ve visited thusfar, Fortuna has been my favorite. And it’s easy to see why!

Finca la Magnita (Selina)

In between Fortuna and arrive at the STRI Research Station in Bocas del Toro, we stopped at Finca la Magnita, a family owned and run farm that practices subsistence and sustainable farming based on a polyculture system. There Orlando, the current owner (and with the help of Andrew who translated) told us about how his farm was run and the different sections of the land. The land there is broken up into around 5 sections: Bosque (Forest), Agroforestal System, Basic Grains, Pasture, and Risk.

1: Bosque: This section is located in the highlands and makes up about 18-22% of the finca. While it does not provide any direct income it provides indirect sources of income through ecosystem services. The only management they provide for the site is maintaining it was a forest.

2: Agroforestal Sysemt: This section while still a forest, it is harvested and maintained to directly bring in money. Located in the lowlands, it makes up about 13% of the finca and produces timer, banana, plantains, cacao, and more.

3: Basic Grains: This section is also in the lowlands but is used to grow maize, rice, bean, etc. This section is used mostly to feed the family and provide seeds for the next year. (Side note: when they switched from their own seeds to transgenic ones the crops did horribly). Any leftover production can then be sold to market.

4: Pastorile (Pasture): This is the section where they get milk, meat, etc. Most of it is also for subsistence: however, they get most of their money from it. They run this section different though from the other farms nearby in that they keep their livestock for a long time, taking the raw products like milk and transforming it into cheese that they can sell at market. The other farms nearby just move their cattle in and out, overgrazing the land and cutting down the forests, which has had drastic changes on coral communities in the Caribbean.

5: Risk: This section isn’t used for anything. It is an area located around the rivers on his property and they are areas set aside that nothing is done with so that it can provide flood control services if the rivers overflow.

But this is not all that the finca does. With their raw products they process and transform them, integrating all the steps in one location which raises the value of the products. Orlando mentioned that for 1 lb of raw coco he will get only 60 cents, but processed he can get $3.50 for the same amount. The finca also holds many educational programs (like the one we were on), where they take groups of people around the finca, showing them how they grow the different products and teaching people how farming in polyculture can increase yield while still being safe for the environment. This is particularly true for the cacao part of the finca, where they cultivate together many different varieties and ages of cacao plants that have different properties (flavors, aromas, smoothness, and seed sizes). By running his farm this way he is able to get a yield much higher than other cacao plantations (I believe 2,000 lbs? compared to something in the 10s place but I don’t remember the exact numbers).Image

More Gamboa Canopy Tower! (Cassie)

Greetings!

Kelsey, Selina, and I walked from the Gamboa Schoolhouse to the top of Gamboa Canopy Tower yesterday. In the excitement to see this place that everyone had already traveled to, I temporarily forgot about my fear of heights–until I got to the top of the tower! Once I was atop the tower, I froze up at the sight of the vast landscape surrounding us on all sides. However, after some encouragement, I managed to put aside my fear and really enjoy the view (and the wind!)atop the tower.

The Canopy Tower!

The climb to and from the tower was also quite epic–it took a lot of endurance (and courage!) to get up the steep inclines on crumbling stone steps. Here’s a view of just the beginning of the journey:

DSC02954

Along the way to the top of the tower we saw a very busy line of leaf-cutter ants, diligently trekking along with a myriad of leaves and flowers. Since each ant carried only a unique piece of a flower or leaf, it looked as if a line of puzzle pieces were marching along the ground. I also stopped to look at some brilliant flowers:

We’re leaving for Fortuna and Bocas del Toro tomorrow so we’ll have lots of posts in the upcoming weeks–stay tuned! 🙂

Lorena: Gamboa schoolhouse

The majority of the IGERT course takes place at the Gamboa schoolhouse, Gamboa.
Gamboa is a small city by the Panama Canal; it was originally built to house the canal’s workers. Its ~40 mins from Panama City by car and ~50 mins away by boat from BCI.

The only way to get into Gamboa by car is by crossing a one lane wood bridge which I find it very unique. This wood bridge also has rails from the train. The bridge was built ~1930s and its still in used both by car and the train.
I always wonder why they haven’t expanded ( to two lanes) but I guess they want to preserve a tradition which as I mentioned is very unique, intriguing and scary ( specially when the train comes) a the same time.

FUN (annoying) fact: The bridge closes from 9-11am every Wednesday for maintenance reason so we better plan our day around that.

The city of Gamboa can be seen at 1:09 in this timelapse video of a boat crossing through the canal.

At the schoolhouse we have a classroom, 4 bedrooms, kitchen, dining area, shared areas and laundry facilities.

Kelsey: Agua Salud

Image

Yesterday, we spent our morning and early afternoon at Agua Salud. This is a large plot of land owned by the Smithsonian, and is dedicated to hydrology – the study of the water cycle. The main idea is that the forest is a sponge – it soaks up excess water during the rainy season to prevent flooding, and then the water is slowly released over the dry season to keep things from getting too parched. This is actually a really controversial issue. Do forests *really* act like sponges? How about cow pastures or farmland? How about secondary forests, which are “new” forests that are taking over abandoned farmland? Dr. Jeff Hall is testing all of these environments and more on Agua Salud, studying the amount of water retained and released in various habitats.

Image

Panama has its years of flooding, and those can be highly damaging. It’s important to understand how land use affects flooding to be able to anticipate disasters. In 2010, apparently the flooding was so high that the dams were at full capacity – any higher and the dams would have broken.

Image

We got to see most of Agua Salud. We were first taken to the teak plantation – teak is a popular wood to be grown in Panama, not because it is well-suited to the soil (it isn’t), but because it’s such a highly profitable venture. People can make a lot of money selling teak wood they grow, so teak plantations are an important environment to study.

Image

We also visited the weirs, small dams that allow people to measure how much water is being released from each environment. Streams have little catchments where water flow is measured, and if flooding occurs the instruments can tell you how much water was added and how long it took for the stream to get back to normal.

Image

We were also taken to the secondary forest to look at how new forests grow. Trees have a variety of different growth rates, and there are trade-offs between growing rapidly (and dying young) and growing slowly (and living a long time). How young forests get and maintain diversity is not well-studied, so there are a few forest plots at different ages used in Dr. Hall’s projects. All of the paint markings indicate the growth rate of the trees.

Our last stop was looking at smaller ecosystems – clusters of only a few types of trees. Every tree has its own carbon footprint and ability to hold and use water, and seeing how specific trees interact with one another can help improve farmlands! It can make the land more efficient at containing excess floodwaters and keep the other plants healthier, if used in the right combinations. It’s pretty interesting how planting a single tree can make a difference!

Image

Agua Salud was beautiful. The views were just spectacular – rolling hills covered in red earth and brilliant green trees, extending for miles. It was pretty hot and we had a lot of climbing to do, but it was a pretty interesting day!
