Final Blog: Forever a TFB

Wow. Even now, I truly cannot believe everything we got to experience and do in these past two weeks. From exploring the forests and the caves at Las Cuevas to snorkeling around the reefs of Glover’s, everything has truly been so unbelievable. The rainforest and the reef, though they are so different, can honestly be comparable to each other as the terrestrial and aquatic equivalents. Both environments host some of the most biodiverse ecosystems in their respective areas, from the insane diversity of creatures of the rainforest to the absurd abundance of fish and corals of the reef. The comparisons between trees and corals is also one that cannot be ignored, especially how both provide structure and habitats for so many organisms, and are arguably the defining trait of each ecosystem. Without trees, there is no forest, and without corals, there are no reefs.

Never had I thought about the two in such similar contexts, but going from forest to reef back to back, these similarities were inevitable. But though they feel like the terrestrial and aquatic counterparts, there are still many a differences between. Everything in the forest felt so hidden, and we had to be actively searching for everything, from small insects like grasshoppers and crickets to larger mammals like agoutis and howlers. The reefs, however, felt so much more open and out there. I noticed how prevalent fish truly were, and how they were literally everywhere. I also noticed how, especially in MPAs, fish were so much more comfortable with human presence as opposed to the wildlife at Las Cuevas, despite both being arguably equally isolated.

But still, both experiences were genuinely insane, in the best way possible. Honestly I don’t really know what I was expecting coming into the course, but I do know I was really only interested in the reef section. The rainforest half felt like a week in between me and a Belizean snorkel vacation, and unfortunately that thought was very prevalent in my mind at the start. What I didn’t expect, however, was how much I would end up enjoying LCRS and the Chiquibul.

By the end of my senior year, I had in some way fallen out of enjoyment with backpacking, and in part a lot with nature and the forests as well. The thought never occurred to me that LCRS could reinvigorate my love for the outdoors and relight the spark I had developed throughout my high school years.

Obviously, as such, I really enjoyed the hikes we had in the Chiquibul. I loved exploring the trails, hiking to the bird tower for both sunset AND sunrise, and our campfire we had before we left. Almost every experience, but these in particular reminded me just how much I missed being out in the middle of the woods, especially with friends.

Though I was most excited about the reefs, at some portions I did feel a bit, not necessarily sick of it, but ready for the reef portion to be over. I think the best way to explain it was during my time at LCRS, I was actively trying to ignore the day we were about to leave, and not looking forward for that day to come. However at GRRS, I found myself counting down the days and wanting to leave all the way up until I was in the boat and we started driving away from the island.

Beyond just what I’ve learned about Orthoptera and Groupers, like how grasshoppers, crickets, and katydids (which I lowkey never heard of before this trip) are actually pretty cool insects, and how groupers aren’t always these giant behemoths roaming around the reefs, I hope that in five years from now I’ll still be able to take away how much nature does in fact have to offer us, even beyond any surface level or economical value. I’ve realized that nature and the outdoors is truly my happy place, and I never want to give up on it ever again.

I also hope to remember just how beautiful nature is when it is completely untouched by humans, and how important it is to keep what little we have left. I hope to always remember the stark difference between parrotfish behavior in the untouched MPA, where they weren’t skittish nor afraid of our presence, versus the place Dr. Evans suspected had been fished, where all the parrotfish were constantly on high alert and would dart away at even a shadow. This in particular really quantified just how much of an impact humans make even when we don’t believe we are affecting Mother Nature that much.

My last takeaway is hoping to remember that no matter how unimportant I feel an organism may be, they truly have a central and vital role to their ecosystem. I came in not knowing how important Orthoptera, groupers, or angelfish were to their respective habitats. They felt like animals that could be cool to observe, but I never realized how important they are to the cycling of nutrients and trophic levels, nor their roles in keeping their food sources in constant check. It fully opened my eyes to how rarely is there ever going to be a species that is truly and genuinely useless, and that, in some way, everything really is by design.

All in all, genuinely, this trip was the experience of a life time. I cannot put into words how fortunate I am to have been able to be a part of this adventure, and having the privilege to experience the pure rawness of the tropical rainforests and coral reefs. I don’t say this often, but I found myself saying this a bit too much for this trip: I will never forget any second of Belize. As they say, forever a TFB.

Here are some of my favorite moments:

It’s been a good one. TFB Ian, signing out.

Day 15: Home Bound…

As I’m on my plane flying back to North Carolina, I’m truly just registering how surreal of an experience these past two weeks have been.

We hopped on our boat back to Belize City this morning at 6:15 AM, marking the end of our stay at Glover’s Reef Research Station and subsequently Belize as well.

I caught one final picture of the view right before I left, in hopes of letting it become ingrained in my memory.

Last night, I returned to the dock to enjoy the sunset one last time. This dock has been one of my favorite places this entire trip, even though it’s not as extravagant nor as exotic as the coral reefs.

The boat ride back was not as fun, and the choppier waters were a lot worse than I remembered. However, it was just as surreal as the way out. We managed to spot a sea turtle, the first and only of our trip, as well!

It felt a little different when we returned to Belize City. Though I had so desperately missed AC and flushing toilets, I did suddenly start to miss the complete isolation of both Las Cuevas and Glover’s Reef.

The flight back was bittersweet, at least when we were awake. I was sad to leave Belize, but the early morning exhaustion fell over our entire crew and everyone was out cold through the flight.

Claire C and I, both from NC, had a flight that was supposed to depart at 6:10 PM, with boarding beginning at 5:30 PM. However, our flight from Belize got delayed heavily, and we ended up landing at 4:50 PM. Fortunately, our flight out of IAH ended up getting delayed, so we made it with plenty of time to spare. Unfortunately, our flight got delayed by almost 3 hours. We ended up departing around the same time we were expected to land, but at least this is better than us missing our flight completely.

That brings me to where I am now, finally on our flight back home, wrapping up our two week stay in Belize.

I’m already missing that dock.

5/29- Leaving it better than we found it

Like two days ago when we explored the coral graveyard, we noticed how polluted the shores of this island is. We all wanted to leave the island a little better than we found it, so today, we spent the morning cleaning up the beach. We had 7 huge trash bags and we filled them up so quickly. We could have spent days collecting all of that trash, because in just about an hour, we filled up all the trash bags we had. As we picked up trash, we collected data on where the trash tended to be most dense on the island. We found that on different sides of the island, the amount of trash was similar, but the distribution was different. On the edge of the atoll, the collected trash was more concentrated in one area, while on the iside of the atoll, the trash was much more spread out due to thte currents.

Then, in the afternoon,  we dissected some lionfish. Lionfish are invasive to this area, and a huge threat to coral reefs, so our professors have been spearing them throughout the week. My llionshidh was very small, so there was nothing in its stomach, and I couldn’t tell the sex. However, it was still interesting to examine the gills and anatomy.

In the evening, we had an optional last snorkel, so obviously, I had to go. Swimming and snorkelling has been my favorite thing to do on the island, and I loved being able to explore the beautiful reefs one last time. I saw so many maze corals, fire corals, and finger corals. I also saw a nurse shark, sting ray, and lion fish.

5/28- Marine Protected Areas

Up until today, we had only explored reefs in marine protected areas. But today, our project centered around how biodiversity is impacted by MPA status. We visited two non-MPA and two MPA reefs. There was an obvious difference between them. The non-MPA reef had fewer fish, and they seemed more wary of human presence than the fish in the MPA. We just learned about MPAs last night from a representative from the research station, a marine biologist, and a member of the Coast Guard. These people together protect the precious ecosystems here, and it’s cool to see how their efforts have a tangible impact on these endangered habitats. Besides this, we had some downtime today to just soak up the sun on the pier. We leave soon, so I’m trying to enjoy every moment.

This is me when I had to jump in to retrieve my sandal.

5/27- Exploring a graveyard

After spending the past few days mostly in the ocean, it was nice to spend today doing some non-snorkeling activities.  We waded in the shallow parts around the dock, just trying to catch anything and everything we could. Our coolest and scariest find was definitely a box jellyfish, which has one of the worst stings. Somehow, no one got stung, and Elise caught it! It’s crazy how something so unassuming can be so powerful. 

We also walked to the coral graveyard. The whole island is covered in fossilized corals, but this part is a particularly large mound of them that has built up over a long period of time. These calcium carbonate fossils are still in very distinct shapes, so you can kind of tell what species they are. I saw elkhorn, staghorn, finger coral, lots of brain corals, maze coral, mound corals, and others that I couldn’t even identify. Hard corals secrete calcium carbonate to make a skeleton, which builds the coral reefs. This process has been happening for billions of years, and when they day, they become fossilized and eventually get compressed into limestone, which we see as the predominant bedrock of many areas in the Belize forests. It’s this limestone that led to the formation of the giant cave structures that we explored. The geological time is incomprehensible to me, and it’s amazing how it is all connected.

At night, we all went to the dock and shined light into the ocean to watch sea creatures. We found a really cool squid, which we caught, watched ink, and messed with it to see it change colors. This was so fun, but I wish it had jumped out at us, which is apparently one of their defensive mechanisms.

5/26 Hunting for Parrotfish

I spent the day with my dive buddy Claire today looking for redband parrotfish. We tried to follow them around the reef for a survey on parrotfish diets. At the first site, we didn’t see any. We thought we had found some, but when we got to shore I realized that all I had were videos of wrasses. At the next two sites, we actually did spot a few! Parrotfish are difficult to spot because the same species can look completely different, so it was definitely a challenge. We ended up finding 6 total, but we only saw the two females eat because the males typically patrol and don’t eat as much. On our parrotfish hunt, I also noticed so many christmas tree worms living on brain corals. These guys are so cute!!! If I were to send a wave vibration towards them, they would sense it and shrivel up immediately. Likewise, we played with some sea anemones, who would also shrink up when u got close to them. It was adorable! I also got to see some yellow pencil coral and lettuce coral here!!! The lettuce coral was much smaller than the pictures I have seen. It seemed to grow in small patches around the reef, so I hadn’t noticed it before.

Wrapping and Reviewing: Thoughts on the TFB Experience

Despite their widely different biomes, the terrestrial tropical rainforest and its lush greenery, compared to the vast ocean and its mysterious creatures, both have developed rich, complex ecosystems. For instance, the forest sustains itself on light and plant matter, reaching different trophic levels and creating microhabitats by temperature and structure to allow biodiverse inhabitants. Similarly, the reefs of the coral reef, fed by billions upon billions of photosynthetic algae, create structural niches for fish and other fauna to reside in, developing hidden habitats as a result. On a greater level, the intense light, heat, and moisture within both systems has become a breeding ground for several producers, enhancing the food web further down levels of prey, mesopredator, predator, and apex predator. 

Personally, I have also noticed that both systems intrinsically propel organismal adaptations (both behaviorally and morphologically) for specialization through competition and symbiotic relationships. For instance, my taxon in the coral reef, the parrotfish, is known for its numerous speciation in the area. Observing their behavior through fish follow studies, we noticed some more adventurous, like the Striped parrotfish, while others like the Redband parrotfish more quickly hiding in reefs. Similarly, the forest’s big cats like pumas often appear at night on the ground while the smaller margay, or tiger cat, hunts its prey on trees despite also being nocturnal. And where there is a will, there is a way. Fungi and insects develop richly on the underside of logs and leaves, in the cracks of tree bark and soil, and atop other living organisms. Inundated with liveliness, neither the ocean nor the forest is ever silent, waiting and adapting with time.

The course far exceeded my expectations. I have been able to pick up so many skills listening and waiting patiently for organism interactions, developing field biology research predictions and methodology, and presenting research. I came in thinking about all the equipment we needed and how unnecessary it probably would be, but I’ve come to value literally every single thing I’ve used in the course, from the thick rubber boots to a tight mask and snorkel. My favorite part of the course is the sheer amount I’ve learned–be it listening to other people’s presentations, or meeting organizers of the various research stations. Another thing that shifted my perspective of both the forest and the reef was witnessing them at night, understanding the enormity of these systems amidst the bright, starry sky. My least favorite part was probably the heat. Traversing the rainforest’s dry season and the atoll’s brutal humidity, I could definitely feel my patience wearing thin at times. Still, it was very character-building. 

Five years from now, I think I’ll still remember a lot about this trip. My favorite, and biggest takeaway: everything can be an ecosystem, especially caves. Caves hold so much geological and biological adaptation, with much continually being explored. Second, ecosystems can be dangerous if you’re not careful. Snorkeling in strong ocean currents or not performing basic stingray (via the stingray shuffle) and snake checks can make or break your life. Thirdly, the more you stare at something, the more life you’ll find. While the reef and forest are not always as dynamic at the macro level, a single leaf can hold colonies upon colonies of lichen. And these relationships are complex, like leafcutter ants with their fungal gardens, adapting for millions and millions of years to form the most astounding dynamics.

Signing off! P.S. some final forest and reef pics 🙂

Day 15: Leaving Belize

Hi Blog,

Today was a bittersweet day, as we had to leave Glover’s Reef but also got to return to the comfort of our homes. After a quick breakfast (of toast and jam), we quickly loaded our suitcases onto the boat then boarded, leaving the dock around 6:15 AM.

During the boat ride back to land, there was apparently another dolphin sighting, but I did not get to spot it, which was kind of disappointing but I was able to see one from last time, so I wasn’t too sad about it. As we traversed through the water, I tried to soak up the gorgeous scenery with my eyes one last time — when again will I be able to see such elaborate mixing of hues in the ocean, from emerald green, to aqua blue, to deep blue?

 

Boat ride back to mainland

This time, I was determined to keep my seasickness under control, so I put on a seasickness patch (obtained kindly from Claire C) yesterday night, the magic motion drops (from Dr. Solomon), and intensely stared at the horizon. Of course, not all of the symptoms were eliminated, but this time with all of the preparation, it was manageable, and we successfully made it back onto mainland Belize at around 9 AM. When we arrived, the van was waiting for us to take us back to the airport. But before getting on the bus, a group of us took a trip to the restroom inside of the hotel, and we were all so joyful to see a flushing toilet after our weeklong experience with Clivus.

The bus then took us to the airport, where we then checked in and made our way to the gates. Since we had a light breakfast, we all grabbed some food for lunch before our flight departed at 12 PM. I got a sandwich and a bottle of Sprite to spend all of my remaining Belizean cash. Having an ice-cold soda after a week of straight-up room-temperature or even warm water felt so good! We were truly returning back to civilization — a world with hot showers, clean clothes, cold beverages, Wi-Fi, and air conditioning.

On the plane, I took a straight 2.5 hour nap (except for when the flight attendant was handing out Stroopwafels). When we landed, I already missed Belize, but I was also excited to finally be back in Texas. We then took the bus to ABL, where we returned our supplies (sleeping bag, caving helmet, dive light, headlamp). It was a full-circle moment, as we departed from ABL altogether, and we returned back to ABL (mostly altogether).

Back in ABL!

We all left the classroom one-by-one, and it was sad to see everyone leave, but a few of us are staying in Houston and are planning to meet up for dinner soon, which I am excited for! These past two weeks have been incredible, and I am so glad that I decided to go on the trip. Truly un-Belize-able.

I will see you guys in my final blog post.

Until then,

Post-Trip: An Un-Belize-able Experience!

Hi everyone! I’m coming to you one last time from the AC back in Austin, Texas. It’s been quite a ride these past 2 weeks. I swam with sharks, took on an army of leaf cutter ants, climbed 11 flights of stairs in one go, caught a box jellyfish, saw a squid ink, met 15 scarlet macaws in one evening, went spelunking to see 1,000 year-old Maya artifacts, and drank water from a coconut. Overall, I’d call it an exciting trip.

I first learned about the tropical field biology course last summer when reading through course offerings. After discovering that the class involved living in a jungle for a week and then moving to a reef to snorkel, I knew I had to take it. After all, when would I ever have another opportunity to explore two of the most beautiful and conserved ecosystems in the world (and get course credit for it : )?

I expected that the course would be both intellectually stimulating and physically challenging. I was right. There is so much to learn from the complex biological interactions of the organisms in the rainforest and the reef. And even though I’ve been observing the plants and animals for the past two weeks, I left Belize with many more questions about how these ecosystems function. However, here’s some of what I learned about the Chibiqual rainforest and Glover’s reef:

Both the rainforest and the reef are incredibly biodiverse ecosystems and I think a large reason why comes back to their locations. The tropics offer almost year-round warmth and intense rainy seasons, which can support a large array of producers and lengthy food chains. There is a large amount of energy that cycles through both of these ecosystems and, because of quick decomposition and conversion rates, it cycles quickly.

Personally, I’ve observed that predation tends to occur frequently in both ecosystems. In the rainforest, I noticed that most ants we found were carrying some sort of plant matter or larvae of other ants. On the reef, minnows swimming near the Glover’s Station dock were constantly being fed on by bonefish and other large predators. Additionally, the striped parrotfish that I focused on for our fish-follow project ate algae off coral and seagrass almost constantly.

Further, organisms in the rainforest and the reef tended to form highly specialized interspecies relationships. The class focused on a few such relationships while in the rainforest such as those between Cecropia ants and Cecropia trees (ants protect the tree in exchange for food and shelter) and leaf cutter ants and fungal gardens (ants cultivate gardens to eat off of). On the reef, we observed another interaction daily: that between photosynthetic algae and coral.

One key difference between the two ecosystems that I observed was their sensitivity to disturbance. On the reef, we were advised to give coral a wide berth. Even brushing up against the coral would kill it as the algae would die off. We also visited the “coral graveyard” at Glover’s, where thousands of bleached coral fragments of many species littered the sand.

The rainforest seemed, at least to me, to be more accepting of changes in conditions and human intervention. In particular, we learned that many species (called “opportunist” species) will thrive in the open space created when a tree falls.

Overall, I believe that there is a lot to be learned from the interdependent flora and fauna of these ecosystems. And one of my favorite parts of the course was going out into the field with a very loose objective and seeing what evidence of cool interactions we could find. In particular, I enjoyed venturing into the rainforest with a shovel and digging into a leaf cutter ant colony the size of a small car to observe how soldier ants defend the nest.

Another highlight of the course for me was the ATM cave. It was by far the most “Indiana Jones-like” adventure I’ve ever had. I am incredibly grateful to have done it with the class, as it made for a great shared experience (and it felt safer to not be going through some of the small squeezes first).

Overall, I’m so grateful for the opportunity to take this course and to learn from some of the most outstanding biologists in their fields and alongside the future most outstanding biologists in their fields. Fifty years from now, I will still remember the view of endless trees and mountains from the birding tower, the light hitting the waves as the sun set from Glover’s dock, and the smell of my clothes after two weeks of no laundry.

BIOS 319 has taught me a lot about the rainforests and reefs of Belize, but I think the main lesson from this course is the importance of going out into new environments and experiencing what’s around you. I’ve learned just how connected the components of ecosystems are and to look for the interactions between organisms that support biodiversity.

If you’re reading this blog post as a prospective student, then I would highly encourage you to take this course. If not, that’s cool too, and thank you for following along on this journey with me. Either way, I’ll leave you with this: everyone needs some adventure in their life. Whether that’s living in a jungle with no AC, warm water, electricity (for some parts of the day), or WiFi, or just going on a hike at a nearby park, there’s so much to learn from the environments around us. So, go get out there and experience it!

That’s all for now!

Day 15: Bye Belize, Hello Houston

The most bittersweet day. We woke up early to pack and aboard the dock, heading on a 3-hour boat ride away from GRRS. I’ll definitely miss the dock, the sun, and the waves. The heat and humidity? Not as much. And definitely not the seasickness (my parting gift on our way back). But still, sailing away across the choppy waters, I could not believe how quickly our reef excursions were wrapping up.

A couple hours later we were at the mainland dock. A bunch of us used the bathroom, which was no longer Clivus. That was also super surreal. And then time to aboard the bus back to the airport.

Bussing to the Belize Airport

And lastly, our flight back home. Before we left, Noelle, Sam, Ian, Dyllan, and I got some really yummy pizza for lunch in the airport. Reminiscing on our time at GRRS and how long ago LCRS seemed, it felt like deja vu that we were taking the same steps back to Houston that we had taken to get to Belize.

Waiting for our ride back at IAH

As we landed in IAH, people began leaving for their connecting flights, until only 8 of the original 14 TFBers were left.

Driving back to the place where it all started

But more to come! Some of us that are still in Houston are trying to meet up, so fingers crossed!
