Day 3: Cameras, Carrots, and “Drunken Baymen”

Hi everyone! Today was a busy day in Belize! We started off the day strong with some bird watching from the station veranda from around 6-7 am followed by a delicious breakfast of eggs, beans, and papaya. Dr. Solomon and Dr. Evans revealed our first big project theme: camera trapping! Camera traps are motion-sensing cameras that take pictures of animals that cross in front of them. It was up to us to discuss as a class what scientific question we would address using camera trapping and how we would go about testing it. We decided to look at how the impact of human disturbance via the presence of man-made trails affects the biodiversity of vertebrates (mammals and birds) surrounding Las Cuevas.

After developing our methodology, we hit the trail. Each student in the class was responsible for setting up one of the 14 camera traps. Seven of us set up cameras in disturbed areas (along the trail) and seven set up cameras in undisturbed areas (50 steps off the trail). I set up a camera trap off the main road into Las Cuevas to the north of the station. Setting the trap required Dr. Solomon’s excellent machete skills to create a path through the thick underbrush.

While we were setting up the traps, we observed several new species, including green anole lizards, tailless whip scorpions, and a true scorpion (we maintained a safe distance). I also tried a new food today: termites! They actually weren’t awful to eat and tasted a bit like carrots.

Post-hike!

We took a break from placing camera traps around noon for lunch, which was rice and beans, pico de gallo, avocado, chicken, and plantains. Side note: I’ve recently learned that rice and beans and beans and rice are two different dishes! Rice and beans are cooked together while beans and rice are served separately.

Plans for tonight include dinner followed by presentations. So far, I have yet to see an amphibian today, but maybe I will be able to find one around the station later tonight. I have met a new friend today though: the stingless bee or “Drunken Bayman.” It is called this because it tends to fly in a disorganized manner. It seems to be following me everywhere. Tomorrow, I am looking forward to another morning of bird watching and exploring the trails around the station a bit more. I have learned the safest way to flip logs which caecilians, salamanders, and frogs tend to hide under, so hopefully I will have an update with an amphibian sighting soon. That’s all for now!

Day 3: Lights, Camera Traps, Action!

Beginning our first full day at Las Cuevas Research Staton (LCRS), we had a scrumptious breakfast before we began our first project. We were tasked to come up with a question and design an experiment, using camera traps, to collect data to hopefully answer it. We landed on the question “How does the presence of man-made trails impact the biodiversity of vertebrates in the immediate surrounding area of LCRS?”

To test this, we set up camera traps on small, medium, and large trails/roads along with undisturbed areas. I set mine up along the LCRS Access road, on a semi-cut down tree!

We also saw a lot of new and fascinating animals today. As I was about to set up my camera trap, we heard a really loud banging noise, and it turned out to be a woodpecker!! Here’s a (blurry) video I took of it: IMG_7122

We saw a fresh track of a large cat scratch, which was really exciting and hopefully a good sign for the rest of the trip.

There was also this really beautiful blue dragonfly that kept flying around us for part of our hike.

My favorite of the day, though, was this baby scorpion that was crawling along the road. It was my first time ever seeing a wild scorpion, and as far as wild baby ones go, they’re not as scary or intimidating as I thought. That being said, we still have to worry about them crawling into our shoes and boots every time before we put them on.

That wraps up our first full day in the field—sadly without any Orthoptera. However, I’m giving my Orthoptera taxon briefing today, so we’ll still get to “see” a few. Hopefully we’ll actually get to see some in the field tomorrow. Until then!

Day 2: Caracol & Las Cuevas

Hi Blog!

Today was Day 2 of Belize. Our morning started at 6:30 AM for breakfast, then we left around 7:30 AM from Crystal Eco Lodge. It was such a cozy and pretty place to stay at, and I hope I can return and stay for a longer duration in the future. Our bus rides were filled with unexpected surprises!

First, on our way to Caracol, we saw not only saw a dead green snake on the side of the road but a cashew nut tree. Before this, I did not know that cashew nuts had fruits attached to them, and that the skin of the fruit contained the same chemical as a poison ivy.

Then, on our way from Caracol to Las Cuevas Research Station, we saw first a Toucan, then once we looked closer, we also saw several Black Howler Monkeys on the trees! There were like 4~5 howler monkeys resting on different branches of the same tree, with even a baby monkey that was hanging off the branch with its tail! It was really cool to see the prehensile tails of these howler monkeys in action! While the baby was playfully hanging off the branch, the other howler monkeys looked like they were enjoying a peaceful nap, as they were draped over the branches and were still for the most part.

Can you spot the howler monkey?

This was especially exciting, since my taxon of primary focus is rainforest mammals, and I had read up all about them! They, like their name, howl to communicate. And their howling abilities are due to the hollow bone in their neck that allows them to produce physical howling sounds!

Our actual Caracol tour was amazing as well. It was so eye opening to see the remnants of the Maya civilization, such as their dwelling and temples. Climibing the many flights of stairs to reach the top of the temple was pretty exhausting, but the view was so worth it at the end! We saw a baby fox in the bricks of the temple, and witnessed it proudly carrying a leaf back to its den. Also, we saw Montezuma Oropendola — the dark colored bird with a bright yellow tail. It was really intriguing to see that their nests were shaped liked baskets hanging from a tree — and there were so many of the nests nearby (in the same tree) to each other.

Caracol ruins!

Tomorrow, we are going to have our first “big project” which I am intrigued to learn about in the morning.

 

 

Day 1: Travel to Belize

Hi Blog!

Today was Day 1 of Belize and it was so much fun!! It was a LONG day for sure, since our class met up at 6 AM and it is now 12 AM. I think we arrived in Belize around 12 PM in Belizean time, and when we got out of the airport it was around 1:30 PM. We got on a bus to head to our resort, and on our way, we had a couple exciting stops!

First, we stopped at Cheers for lunch, where the food took a bit to come out but it was such a cute place. There were old t-shirts hanging from the ceiling from different groups that have visited the restaurant over the years, and outside, there was a little playground and a small body of water. This was super cool because we saw iguanas in the trees, and they were jumping into the water — although my reaction time was too slow for me to catch them in action on my camera.

Then, on our way to a supermarket, apparently there was a roadkill Tamandua Anteater on the road, but I didn’t get to see it. Hopefully we can spot another one soon (alive as a bonus— fingers crossed), or even a Giant Anteater! I also saw many horses and cows on the way. Many of them were just grazing on the pasture, but I also saw a couple of horses just stationed outside of a family dwelling.

I really enjoyed the ride because the views were very scenic, and I loved the differences in geography and architecture. All of the brightly colored houses coupled with the mountainous landscape and blue sky were surreal.

Vibrantly-colored Belizean houses!

When we got to our resort, we were greeted with two very friendly dogs — my first actual mammal interaction in Belize! They loved pats and rubs, and one of them actually led Dyllan, Lily, and I to the river when we were slightly confused on how to get there. After we arrived to the river with his help, the dog stayed around us, traversing from person to person for extra snuggles (which he of course received!).

First mammal interaction – a dog!

I’m looking forward to tomorrow to a full day of adventures!

With love,Sohee

Day 3: Watching the forest

Today we set up our first field experiment of the trip. We were presented with motion-activated camera traps and challenged to come up with a research question we wanted to investigate over the next five days. These camera traps would take photos whenever they detected movement, allowing us to look at animals when there aren’t any humans around. With these cameras, we were challenged to design a simple pilot study that we could carry out. We decided to look into the differences in biodiversity between areas with manmade trails and areas that hadn’t been disturbed. We had 14 camera traps, so we determined 7 different locations along trails and roads of different widths, and then decided to associate each trail camera with one deeper into the underbrush. By 9:45, we had designed our experiment and were ready to head out into the forest around Las Cuevas.

In the morning, we set up six of the cameras. It was a bit slow-going at first as we perfected the method, but by the end of the morning we were experts. We each took turns setting them up—I went third. It took some bushwhacking to set up the traps in the undisturbed areas, but that allowed us to see some impressive wildlife and trees. One of the earliest things we saw was a big cat scratch on the trail. Hopefully, with cameras nearby, we’ll be able to see some actual big cats by the end of the week. I also saw some massive leaves among the leaf litter, which I think belong to the Bigleaf Grape. We also saw the large, spiny outer shell of a seed pod of a palm tree as well as a bird of paradise plant.

After lunch, we did a different loop and placed the eight remaining cameras, including on the road leading to the research station. We were much more exposed in the afternoon, and as it grew hotter and hotter, I started to notice that my sweaty hands were partially erasing and smudging my field notebook. It’s a bit annoying, but now that I know about it I can mitigate the issue. It was also the first full day of field work, which was punishing but manageable. I’m staying hydrated and getting rest when I can and I think I’m managing it just fine.

The day isn’t quite over yet—this evening, I’m giving my topic lecture. I get to share what I learned about the biological history of the region. I got a preview of it today, when we saw trees adapted to fending off giant ground sloths, which are extinct now. I think it’ll go well. I’m interested to see what our cameras will pick up—I’ll be sure to update when we collect them again at the end of the week.

Day 2: Monkeys, Ruins, and Angry Ants

“Toto, I’ve got a feeling we’re not in Kansas anymore.” Today, our group officially entered the jungle with a tour of the ruins of Caracol and a hike around Las Cuevas Research Station. While I encountered neither an amphibian nor an angelfish (I would have been really surprised to see that one), we saw many amazing species. While at Caracol, we observed a species of bird called Montezuma’s Oropendola. This species has a long tail with yellow feathers and builds pendulum-shaped nests. Our guide, Leo, noted that if the female Oropendola does not approve of a nest, she will push it to the ground and the male Oropendola will have to build another. We also observed several Howler monkeys (including a baby Howler monkey) and a Toucan from the road out of Caracol.

Caracol is a site of ancient Mayan ruins and we had the unique opportunity to climb the stairs to several large temples. I particularly enjoyed the view of the surrounding forest from the top. One of the structures we climbed remains the tallest building in Belize to this day. I learned a lot about Mayan culture and traditions, including their practice of playing ball games in large areas surrounded by rock walls, sometimes as a means of war.

After the tour of Caracol, our group arrived at Las Cuevas Research Station. We took a short hike around the area and observed several epiphytes and ant species. We discussed a bit about the mutualistic relationship between the bull-horned acacia and acacia ants after observing them on the trail. Acacia ants will fight anything that touches the acacia plant in exchange for food and shelter.

It was exciting to see these species in person after learning about them in biology classes in prior years.

We ended the day with dinner (pork, mashed potatoes, bread, and vegetables) and presentations. I am looking forward to exploring Las Cuevas more tomorrow with our first big project! I plan to wake up around 6 to bird watch before breakfast. That’s all for now!

LCRS Full Day 1 and First Big Project! (And, as always, ants!)

Day 1 at Las Cuevas (May 18)
Today was another great day here at Las Cuevas! We began our first big project for the class, and the prompt was to use motion-detection cameras in some way. We decided it would be best to use them to assess animal motion on man-made trails (disturbed area) versus undisturbed area. We settled on the research question: How does the presence of man-made trails influence the biodiversity of the vertebrate animals in the immediate vicinity surrounding the LCRS (Las Cuevas Research Station?)
We decided to set up cameras both on trails of all sizes (Small Mayan and Bird Tower Shortcut Trails, Intermediate Monkey Tail Trail, and along the overgrown San Pastore Road and the more maintained main access road) and for each camera set up on a trail, there was one ~50 steps into the woods to monitor undisturbed animal activity. My camera was set up in the woods near the Monkey Tail Trail, at N 16.73019, W 088.98109, in case you were interested.
It wouldn’t be my blog without this next part: the ants of today! The morning was fairly ant-less. There were ants, but I didn’t see anything too noteworthy. The afternoon, though, was quite fun. Early on (first 5 meters of the Bird Tower Shortcut Trail) we saw a leaf cutter ant pathway breaking up leaf litter. I thought it was cool how the leaf litter was broken up in their path, that shows often they walked it & how many there were. After that, we saw a leaf that had been cut up by a leaf cutter ant, which was really cool! Dr. Solomon shared that these ants have zinc-lined (really really hard) mandibles with which they clamp on to the edge of a leaf, vibrate (like a jigsaw,) and rotate their bodies to carve out a semi-circle shaped piece of leaf roughly the size of their bodies. In the image below, the size of the semi-circle gives the size of the ant! After a bit of time, I was bored while people were setting up their cameras, so I went and caught a leaf cutter ant with the pair of forceps (pictured below!) This was the first of what I assume will be many ants caught this week. After that, I found a Pseudomyrmex family ant on a flower. I was initially puzzled because this was a less likely species to see, but when I realized the large silvery eyes, I could tell it was a Pseudomyrmex. If I had to guess specific species, I would guess Pseudomyrmex gracilis. That’s all I got ant-wise for today.
What a great day, and I can’t wait for the adventure tomorrow will bring!

Day 2: Exploring the Maya ruins

Today was primarily about the Maya ruins of Caracol. We left Crystal Paradise Ecolodge after a delicious breakfast and immediately headed for the Chiquibul National Park, one of the oldest in Central America. Along the way, we passed the the Mountain Pine Ridge, where the typical deciduous canopy gave way to pine trees due to the differences in the composition of the soil. The checkpoints are there to reduce the impact of illegal logging. We learned that logging was super restricted in Belize, including thst the country as a rule does not export timber, only finished products, in order to reduce demand. Interesting to see how the nation is trying to protect its historic forests. At one of the checkpoints on the way to Caracol, I saw a cashew tree for the first time. They’re quite odd looking—I never would have expected cashews to grow at the base of a whole fruit. It’s strange to see—I’ve included a picture here because I almost didn’t believe it myself.

The big ticket item of the day was Caracol itself. It’s an ancient Maya city, mostly buried. The parts that are excavated are quite impressive—temple complexes, ball courts, and residences. The main palace is still the tallest structure in Belize! Our guide told us that, because of their animistic beliefs, when the Maya stopped using a building they buried it and built the next one on top, and that’s why Maya buildings are on such tall mounds. We saw many of these mounds and buildings, including a whole astronomy complex which was oriented so that it different buildings tracked the sun as the seasons changed. It was all fascinating history, and a history I haven’t learned much about in the past.

I was focused primarily on the trees we saw, though. On the drive, we got to see a number of Trumpet trees, particularly in the disturbed areas by the roadside. At Caracol, there were also these two magnificent Ceiba trees. They were so close together, which was surprising, considering normally their canopies spread out quite a bit. You could actually see the canopies avoiding eachother. We also saw an avacado tree (although the fruits were not ripe) and an interesting parasitic relationship between a Cohune palm and a strangling fig epiphyte, which would eventually kill it. There were tons of other interesting plants and trees as well, like agave, the tourist tree, bay cedar, and more. In addition to the trees, we got to see grey foxes, howler monkeys, and a toucan! 

Around 4 PM, we finally got to Las Cuevas. Our encounters with Maya ruins weren’t over, though: Las Cuevas is also built on an unexcavated Maya ruin, and many of the ‘hills’ around the place are Maya structures. We went on a preliminary hike through the Maya ruins around Las Cuevas and saw another ball court and temple complex built atop the caves.   This site was apparently more likely a pilgrimage site than a permanent settlement, we were told. We ended the day with another round of presentations and settled into our rooms at Las Cuevas. I can’t wait for tomorrow—so far we’ve just been doing travel and getting set up, but next we’re going to get to start doing research.

(Final note—we have limited wifi, so although I’m writing these daily, some, like this one, will be posted later. Sorry for the delay!)

Day 2: Life under the sun!

Today we drove for a few hours through a pine ridge ecosystem into the Chiquibil National Forest! We stopped at Caracol, Maya ruins deep in the rainforest 3/4 of the way through our drive where we learned about Maya civilizations. We walked around the large site seeing bases of what used to be homes and temples in a sprawling city from 200-1200 CE/AD. There were huge palm trees with parasitic fig trees suffocating them and some very fragrant wild cilantro plants. I saw a small brown anole on one of the trees in the middle of one of the family housing areas. It was about 6ft up the trunk of the tree.

The largest ruin was in a wide expanse of sunny fields. It is the tallest structure in Belize, and we climbed all the way to the top! At the top we could see miles upon miles of mountains. Archaeologists suspect was the home of a local king, and at the top of the ruin was a temple to the sun god. We spent a good amount of time exploring the ruin, and though I was sweating through every layer of clothes, I loved every moment. I also saw a small brown lizard on the outside of the sun temple. Before we left the site, we saw a baby grey fox in the rubble of a partially excavated ruin.

We continued our day by driving to Las Cuevas Research Station, our home for the next few days. The jungle got consistently denser the further we drove; we even saw a toucan and some howler monkeys on a tree on the side of the road.

At Las Cuevas we took a short walk through the rainforest where I saw a blue tailed skink in the hole of a tree. Now we have started wearing boots anytime we go outside of the research station fields just in case we come across any venomous snakes. Hopefully we see some but not too close.

All in all, today was a super fun day and I successfully ended our sunniest day of the week without a sunburn!

See you later!

Caracol and LCRS Night 1!

May 17 – First Full Day, CPE —> LCRS Travel Day, Caracol Visit, and Inaugural Hike
Hello! Today was yet another great day here in Belize. When we woke up, we were met with a lovely breakfast from the Crystal Paradise Ecolodge before we hopped in the van for a ride to the Caracol Maya Ruins. Caracol was one of their larger cities, with a 5 mile radius of the site, 35,000 structures, and an estimated population of 200,000! Visiting the site and seeing the ruins, along with the beautiful Cotton Trees (pictured below with large above-surface root systems called Buttress Roots) was so awesome!
In addition to the ruins of Caracol, we arrived at Las Cuevas Research Station (our home for the next week) and had our inaugural hike! This was a short hike along the Mayan Trail, where there was no shortage of diverse ants! I saw some stray ants on leaves and the ground, but the real excitement came early on: we saw army ants! They were marching along the path, and marching back the other direction with objects they to bring back to their bivouac, a temporary colony home (as opposed to a traditional ant colony) that is in place for only one reproductive cycle. After the cycle, the entire colony will move to a new place with new forage-ables. When we moved on, after a lull in ant-spotting, we came upon a Bull’s Horn Acacia tree. I know what you’re thinking: what does a tree matter to the ant man? Well, this tree has a secret (unless you disturb it, then it is not a secret.) The tree is protected by ants through a symbiotic relationship! The tree provides shelter in its hollow thorns to the colony, while also providing both carbohydrates and protein, making a full meal. The ants never have to leave! Their rent? Protection. If someone even messes with the tree, the ants will attack that individual (person, animal, rock maybe?) So, for just a 30 minute jaunt in the woods, there was a pretty great amount of ant-stuff to see!
