Bye rainforest! 5/22

Its our last night at Las Cuevas, and I am exhausted. Luckily today was a pretty chill day so I got some downtime to rest. In the morning, we did our last hike to collect all the cameras that we set up earlier this week. We were all hoping to find a big cat, and we did!!!! We got a few pictures, that we think could be up to 3 different pumas! Pumas are territorial, so they are likely to be the same one, but it’s fun to think we caught a bunch. We found that animals like the man-made trails that experience low-traffic compared to undisturbed areas. It was so fun going through these pics.

Today I also gave my last presentation. It marked the beginning of our coral reef ecosystem, with my taxon, hard corals. I’m so glad to be done with my presentations and it made me so excited to start exploring Glover’s reef soon

To end the day, we hung out by a fire near one of the mayan ruins. We found a huge moth wing here, which I think belongs to a polyphemus moth.

We all laughed and looked back at our week here. My favorite part so far was definitely catching a butterfly. My least favorite part has to be how much my feet ache, especially in the rubber boots. And overall, I can’t wait to identify hard corals, see stingrays, and watch sunrises and sunsets from the island.

Goodbye Rainforest, but Not the Cockroaches!

Today was our last day in Las Cuevas! We started the day by collecting our camera traps. It took wayyyy quicker than it did in the morning. We’re practically experts on the trails now. We then listened to a variety of presentations about both parasites and infectious diseases in the forest and about the reef which is our next stop!

In the afternoon we all took a brief rat and studied outside together while we had WiFi. After dinner was when we got to see the images our camera traps had taken! There were a lot of candids of people on the cameras but we managed to see some amazing wildlife. We saw three pumas, several turkeys, and a few birds on the cameras! We were all super excited about the pumas as we all really wanted to see a big cat in the jungle, and our wishes came true!  We ended the day with a special campfire in the middle of the jungle.

Dr. Solomon also had caught a bioluminescent click beetle and showed the class. These beetles are especially cool because not only do they glow through friction on their wings but they use friction to create a loud snapping sound when touched to scare and startle predators.

Day 6: Boiling in Belize

Hi! Today is day 4/5 in the rainforest! And it was definitely a hot one! Today we got a special tour of the Las Cuevas Cave. We were shown the main chamber and you could see stairs winding down to a cenote built by the Maya. We were told the cave represented the border between the living and dead and was an entrance into the underworld. The cave was probably used for religious rituals the maya did. We were able to see remnants of charcoal and pottery from those rituals.

In the afternoon we collected our pitfall traps and analyzed the amount of species and what species fell into which vials. We found that the difference in the tree in the pee vs water vial was greater than the difference in the ground vials. This signified  greater nitrogen limitation further from the ground.

We then hiked to the bird tower for sunset where we got a great view of the rainforest as the sun was setting. Along our treks we saw a few beetle species including a long horned beetle!

Parrots, Ants, Beetles oh my!

Hi! Day 3/5 in the jungle! Today we listened to a lot of presentations. One was by the head of FRC where we got to learn more about their mission and role they play in LCRS and the surrounding areas. The other was about the caves here in LCRS and the cultural importance of them.

Then we did a leaf cutter nest extraction. We found  young leaf cutter ant that looked to be about 1.5 years old and had few ants. We got to see the queen on the fungal garden and see how big she was! This nest was young enough that the hive had no army ants yet. We then extracted an older leaf cutter nest that was about 20-25 years old! That one definitely had army ants. We were stomping our boots left and right. This nest had a guest cockroach and was absolutely massive. We dug in through the side to find the fungal garden of that nest as well. That fungal garden was huge with multiple chambers.

We then went on a night hike to finish the day. We put on our head lamps and headed out. Unfortunately we didn’t see much but a few cockroaches, tarantulas and other insects. We did see a lot of beetles though! There was one during dinner and a few during the various hikes throughout the day. The beetles we found were dung beetles and herbivores beetles.

Day 4: Into the Thick of It

IMG_0329Hi! We’re still in the heart of the jungle, on day 2/5 at Las Cuevas. Today was a busy day with us successfully setting up two research projects!

This morning we set up a research experiment using pitfall trap to try to see the nitrogen limitation between the forest canopy and ground by seeing the difference between invertebrates in the nitrogen (our pee surprise!) and the water pitfall traps. We spent the morning setting up the experiment on several trees.

In the afternoon we set up another research experiment to see if bullhorn acacia trees change their defense mechanism based on age and colonization of ants. Usually a Bullhorn Acacia tree has a mutualistic relationship with ants where the ants live inside the hollow tree and are provided food by the tree. In return the ants provide a protection to the tree from herbivores. We collected leaf samples from a young and old acacia tree and several different species of invertebrates from grasshoppers to crickets to katydids and put them inside with the leaves to measure change in biomass and monitor the insects health with close proximity to the plant.

Along our treks on the woods we observed several different cool species from a queen ant who had just mated her larvae in a young acacia tree to many different tarantulas. We also saw several beetles. Of note Sam found a Tiger Beetle which is really cool because those beetles are very fast!

Mayan Ruins + Welcome to the Jungle

Today marked day 9 of the trip. The overarching goal was to travel from the TEC to Las Cuevas Research Station. However, we made a stop to tour the Caracol Mayan ruins along the way!

The tour was 2.5 hours long, and I enjoyed every single minute! Leo (our tour guide) taught us so many Mayan/Belizean history facts! We saw Ceiba trees, and they were huge! The most impressive part of the tour based on the monumental size was climbing the temple/palace of the plaza. The stairs were incredibly steep, but they were so worth it! At the top of the stepped temple, I stood at the highest point of Belize!

On the rest of the tour, it began to rain. When I was taking cover, I got to see some Oropendola montezuma! These are a large species of bird that have black bodies, yellow tails, rufous wings, white cheek patches, and a pointed orange beak. Scott described perfectly how their songs sound like video game noises. I also saw their nests, which they weave themselves, and they look like sacks hanging from branches.

I also saw many other birds: blue-crowned motmot, great-tailed grackles, melodious blackbirds, a type of vulture, a type of hawk, a pileated woodpecker, and (only heard the calls) red-lored parrots.

During the drive from Caracol to Las Cuevas, I very briefly saw scarlet macaws! They were in the distance in tall, sparse trees high in the canopy. I hope to see more!

I gave my rainforest taxon lecture today on birds! I was excited to get to fangirl over my taxa, but sadly, the audio files didn’t work. Even though people didn’t get to hear the bird calls for the species I presented, we will push through TFB-style and still test out our abilities to bird by ear regardless (at least I will)!

Liliana and I are staying in room “Jobillo” at the station. Early tomorrow morning, there will be an optional birdwatch. Since I am extremely tired and am aware that tomorrow is going to be a long day, I plan on going only if I’m naturally awake by then. If my internal timing of waking up allows me to make the morning birdwatch, then I will have so many more sightings to add to my taxon log!

The jungle puts my Belizean ecosystem count to 3 (atoll, savanna, rainforest)!

We’ve been home a little over a day now, but my brain is still reeling from this incredible experience. We may have been bitten by bugs or burned by the sun, but this trip is one I’ll always remember. I relished the opportunity to learn about field work and to do science experiments in new environments with people who are just as passionate as I am (if not even more!).

 

I had never really visited a rainforest in its pristine quality such as the Chiquibul area around Las Cuevas. There were just so many hymenopterans, insects, and plant diversity. My expectations were high due to the Planet Earth’s wonderful episodes, but wow, I was still floored.

 

Similarities wise, when comparing the rainforest to a reef, there is an equal amount of diversity—there are plants and coral that are common or rare (for their respective ecosystems), and the same seems to apply to animals/fish in both places! It’s just wild to me how such brilliant ecosystems can support as much life as they do. I was also shocked at just how much rain affected the rainforest. The first heavy rain ignited the nuptial flight for some termite and ant species! I know that rain affecting the rainforest seems obvious, but this nuptial flight and predictability of some fauna presence made the whole phenomenon magical.

 

Despite the obvious difference of salt water vs. freshwater and marine vs. terrestrial, I felt that there wasn’t much that differed. Of course, the biological diversity and make-up of the ecosystems are totally different. But if one were to equate a tree to a coral, and a reptile to a fish, one might find similar compositions and proportions of those species. However, now that I think about it a little more, there are SO MANY undiscovered arthropods in the rainforest, and probably just as many microscopic organisms in the coral reef. If I had to guess which ecosystem has greater biological richness, my money would be on the rainforest.

 

This course was everything I hoped it would be and more. I surely expected more mosquitos in the rainforest and less on the island, but the opposite was true. On a more serious note, I am really pleased with how our group got along, how we approached each poster/project, and just hung out in the downtime. Academics wise, I really felt like I learned a lot about ecology, which as a BioSciences major, I don’t have to study in total depth. If I had to pick three things that will stick with me forever… humm

  • Scarlet macaws are endangered due to poachers who steal their babies to sell as pets. This was surprising to me because finding their nests must be pretty hard already!
  • Frogs are really hard to find in the rainforest, especially during the dry season. Also, their sounds can deceive the human ear, and it sounds like they go in all different directions. I was actually shocked by the chorus of the rainforest at night, and I couldn’t really distinguish which animals were making what sounds.
  • Corals can form viable hybrids that could help increase genetic diversity and resilience of global warming effects in the ocean. This is just incredibly crucial to the future of coral reefs.

 

If I really had to pick a favorite part, I would say that snorkeling in the forereef and in the backreef, with such still water, was truly a once-in-a-lifetime opportunity. There was just such a range of fish—in age, size, color, and species. And the coral/sponges were also spectacular. And the water was so blue. And the list could go on.

 

My “technically” least favorite part was the humidity in the rainforest. So dense and thick, I almost found it harder to breathe. Now, this also could have to do with my being out of shape from the semester, but either way I was surprised.

 

And truly, if that is the worst thing I can say about this trip, then amen—this was truly an incredible trip. I am so thankful to have had the opportunity to go to Belize.

Day 6: The Day the Insects, Rain, and Southern Mississippi Took Over

Written 12:30 pm May 21st

 

This post was supposed to be written last night (May 20th), but then I took a Benadryl (#thankschiggers) and fell asleep while typing.

Shoutout to Mom and Jems for a happy birthday!

 

Yesterday, we spent half of the morning collecting our urine and water samples. Veronica netted another Mexican Tree Frog, but this one had varying shades of brown and green to help it camouflage in the leaf litter. When we returnred, we started analyzing our catches. (Check out Day 4 for the background on this project.) So basically, for the next 5 hours, I looked at insects of all different kinds. Standing over a bunch of springtails, flies, etc and helping our experts (other students who looked at those insects closely) was frustrating but rewarding. Also, everything smelled like urine.

While we were analyzing data, a huge thunderstorm cracked through the sky and we had the chance to get rained on in the rainforest! Scott was especially excited because the first big rain of the season triggers social insects’ nuptial (mating) flights. A few hours later, there were termites EVERYWHERE, and their wings shed very easily.

After the thunderstorm, a group of 25 from Southern Mississippi University arrived. The instructor for their course was intrigued with our insect project, and so he asked if we could present to his group on our urine insects. After much convincing, the group unanimously decided to go for it—and along the way we made all the “pee” puns. We were sad that our personal research station was no longer just ours, but we also had a great icebreaker to meet some new people.

Day 5: Our First Poster Day

Written on May 20that 6:17 am

 

DISCLAIMER: Las Cuevas was supposed to have internet—right now, it isn’t working. All LCRS posts from the rainforest will be posted after the fact!

 

Well May 19thwas a day for the books! We were tasked with our first project that we were to start and finish in one day. We were attempting to look at new pioneer plant biodiversity in hurricane gaps with tree regrowth vs not.  However, the hurricane gaps (tree fall areas induced by hurricanes) were so dense that we couldn’t enter the forest with the methodology we had created. So, we just ended up looking at plant biodiversity in hurricane gaps vs. forest.

We collected leaf samples from 10 different plots and then sorted them into morphospecies (categories of leaves that we think looked like the same species, not rooted in actual knowledge). It appeared to us that there was no significant difference between the two—had 30 morphospecies in gaps vs 28 in forest. We made a very lovely poster, and Scott thoroughly enjoyed our presentation.

After that, I gave my presentation on Amphibians! Everyone really liked my Frog and Toad slide especially. We had hoped it would rain so that there would be frogs out during our night hike, but unfortunately, it did not. We could hear frogs but unfortuantely couldn’t see them. I don’t think my eagle eye spotting was the best, and I was still somewhat confused by the calls of amphibians vs. insects, so the sound was hard to follow.

However, we did see lots of nocturnal reptiles including mud turtles, a red backed coffee snake, and a banded gecko! I also really enjoyed listening to the insect chorus of communication throughout the night. And I even had a chance to feel like Newt Scamander when I held a stick bug that looked a lot like a Bowtruckle! 🙂

Day 3: Surrounded by Green

Written on May 17that 9:31 pm

 

DISCLAIMER: Las Cuevas was supposed to have internet—right now, it isn’t working. All LCRS posts from the rainforest will be posted after the fact!

On our first full day at LCRS, we started our first project! We were given a method (camera trapping) and were tasked with creating a question, testable hypothesis, and a full methodology. After much discussion, tweaking, and organizing, we decided to ask about human impact on mammal traffic. We measured this by setting camera traps in pairs—one on the trail facing the trail, the other off trail facing away from the trail. We hope to catch some great cat (like jaguar) shots!

With all the details figured out, we left for to set up the first three pairs. We went from the station, down Monkey Tail Trail, and turned onto Saffron Trail. This broad daylight hiking was different than yesterday—the sun rays glowed through the trees lighting up the forest canopy with all shades of green. Most notable canopy spotting today was a large termite nest in the Y of some branches; it had to be at least 5 ft in diameter!

I sadly did not spot any amphibians today—I think this is because it is the end of the dry season, and not that many rains have come yet. Also, most of the Belizean frogs are nocturnal and we’ve just been hiking in daylight or dusk thus far. The tree frog from yesterday was really a treat!

Somewhat related to amphibians are boa constrictors! We actually had the incredible opportunity to spot one in the wild while hiking off trail to set the camera trap. The boa was directly in front of a 30 ft wide leaf cutter ant pile, so we were all having a field day with this nature sightings. The snake, on the other hand, was very nervous but never lunged—it just followed any moving person with its eyes.

When we returned from our hike, we had a chance to shower then hear from the Director of Friends of Conservation and Development Raphael. He explained to us that (in a nutshell) his NGO is responsible for patrolling the border with Guatemala and other high-risk areas to protect the wildlife. All in all, today I learned to appreciate the rainforest, and even more, the colors and battles of the rainforest of today really made me appreciate being in the rainforest.
