And that’s a wrap

This trip was one of the most amazing experiences of my life. Not only did I learn a ton, but I also discovered how fun and rewarding field biology can be.

In visiting both the tropical rainforests and coral reefs of Belize, we were able to experience the two most biologically diverse ecosystems on the planet. Though at first glance these ecosystems may seem very different, they actually share many characteristics that may contribute to their amazing biodiversity. Both tend to exist in the tropics (as seen by the existence of both in Belize), where stable temperatures, large amounts of sunlight, and/or long evolutionary lineages may contribute to extreme biodiversity. Additionally, both rainforests and coral reefs often exist in nutrient-poor environments, and thus nutrients are cycled through the communities rather efficiently.

The rainforest and coral reefs had incredible structural diversity. In general, the rainforest’s structure was provided mostly by plants, while the reef’s was provided mostly by coral colonies. With so much structural diversity comes the creation of a plethora of niches for species to inhabit, thus allowing for many species to exist in the same ecosystem. In both areas, we saw countless species from many different taxa, some of which seemed similar but in reality had slightly different ecological roles. The species compositions of the rainforest and coral reefs were of course very unique. For example, very few mammal species exist in the Belizean reef environments, but a large diversity of mammals exists in the Chiquibul forest.

One specific similarity that I noticed between the rainforest and reefs was the complexity of their trophic pyramids. For example, on a coral reef, a great barracuda could eat a Nassau grouper, who could eat a bluestriped grunt, who could eat a clam, who may filter feed on plankton. This complexity is very interesting, and as the “expert” on mammals and piscivorous fish, I found it really exciting to be able to observe some top predators in the wild.

The only thing that this course did not provide me with was a sighting of a wild jaguar (which only means I need to go back!). It really was everything I could have hoped for. There was more scientific methodology practice than I had expected, but I think this was very helpful for learning about how science works in the field. My favorite part of EBIO 319 was just being able to explore the rainforest ecosystem, whether through early morning walks or camera trap images. My least favorite part was probably the pre-trip preparation (which was a bit stressful), but I think it all paid off in the end.

Three of the most important things that I learned on this trip:
1) Living in a more sustainable way, by focusing on true needs (like hydrate or die) rather than superfluous wants, is incredibly rewarding and strengthening.
2) Seeing an elusive creature (such as a tayra) in the wild, even if it took hours or days of seeing nothing, is absolutely worth the effort.
3) Even with little sleep, few snacks, no internet, cold showers, limited electricity, and lots of ticks, field work felt rejuvenating!

Overall, a completely unbelizeable experience!

So long, Belize (for now)

Today was officially our last day in Belize. I didn’t want to leave that beautiful country, with its pristine natural places and amazing people. I plan to return one day soon!

Even though it was our last day, we still had work to do! We left Glover’s at 7am with a packed breakfast, and headed out to Carrie Bow Caye. This island is only an acre in size, but houses the Smithsonian research station. The volunteer station managers gave us a nice tour, and we got to meet some of the researchers doing work there. The station seemed like a really nice place to do field work.

After Carrie Bow Caye, we travelled to Twin Caye, an island separated by a narrow channel. Here, we got to explore the infamous mangroves. Luckily, there were almost no mosquitos or sand flies. The mangroves are an incredible environment both above and below the water. The mangrove tree species have evolved special adaptations, such as aerial roots, to deal with the high salinity of their environment. Underwater, the trees often have mutualistic sponges attached to their roots. We saw many species of juvenile fish swimming throughout the tangled root systems, as mangroves often serve as fish nurseries.

I saw a small school of juvenile needlefish in the mangroves, and other students reported seeing a barracuda as well. Since so many fish species start their lives in mangroves, it is paramount that these ecosystems are preserved.

After getting back to Belize City around noon, we had another lunch at Calypso restaurant, and then said goodbye to all the Glover’s staff that had been so helpful to us throughout the trip. Then it was off to the airport, and back to Houston (thankfully, no transportation troubles this time).

I’m out like sauerkraut

It would be impossible to write down even a percentage of the things I learned on this trip, but I will attempt to do it justice in the small amount of space I have here.

The most important thing I learned was how to stay positive and roll with the punches even when nothing is going according to plan. I also learned the importance of keeping your relationships strong with those in the field. There were so many times when we relied very heavily on people that Adrienne and Scott had worked with many many years in a row, and they were the people who helped us out the most when things went wrong. I also learned how integral it is for everyone to be involved in conservation, not just those that spend their lives on it. No one organization can do everything, and often conservation is the most powerful when whole countries or groups of people get invested.

I also learned tons of skills like how to string a quadrat, how to snorkel while not kicking the corals around you, how to create pitfall traps etc., but I won’t go into the nitty gritty details of all that.

I think most importantly, I learned about how similar the coral reefs and rainforests really are. Not only are coral reefs and rainforests facing similar threats in the forms of human development and changing global temperatures, but also they are both highly diverse ecosystems that support some incredible life that is important for people all over the world. The rainforests and coral reefs are very nutrient poor environments, and the organisms that break down dead, dying, or lysed material have to be efficient in order to the other organisms to be able to use those recycled nutrients. This cycling is how both environments maintain such high diversity in such nutrient poor environments.

Furthermore, both environments deal with medium levels of disturbance regularly in the form of large storms, other natural disasters, and human activity. This disturbance ensures that no one species is able to dominate the ecosystem, which helps maintain the high levels of diversity we see in both the rainforest and the coral reef.

Some of the physical similarities I was able to see was the presence of dominant large species that help build homes for smaller species. In the rainforest there are dominant tree species and then smaller trees or vines that take advantage of those species. On the reef the dominant reef builders are in the form of stony corals which provide homes for fish, worms, endolithic borers. They also end up being the framework for a lot of other corals or once they die they are colonized by macro algae, fungus and/or other corals.

This course surpassed my expectations in a lot of ways. I was expecting to learn some field techniques, have some fun along the way, and get a little dirty. In all aspects I was surprised. I not only learned field techniques, but also how to deal with what to do when things go wrong in the field. I had more fun in this class than I have had in any class ever, and the people I got to meet along the way made it that much better. Also, I definitely got dirty.

If you forced me to pick a favorite part of the trip, it would be the day we went out into the ocean to the fore reef and got to see the wave action, all the different species of coral, and the large fish and rays out there. I think as far as least favorites go I wish I had brought more cortizone cream and new how to deal with rashes better, although the blisters were also pretty bad.

Now that I’m done with this class, I’m going to need to find something to fill my days. So if anyone is looking for 13 mile hikes in Houston, hmu.

The last day, Day 15 :(

Today we woke up extra early and hopped on our boat. We went straight to Carrie Bow Caye and met the volunteer managers of the Smithsonian’s research facility there. Surprise surprise, they are from Bois, Idaho! Perhaps this is a sign that I should return to here next summer. The island is so tiny, only about an acre and a half, and it grows smaller and smaller every year as sea levels rise. A lot of researchers go there to do there work, and I can see why. There is easy access to seagrass beds, mangroves, the fore reef, and back reef.

After that we went to Twin Caye and explored the mangroves. I cut my leg a little on accident but oh well. Mangroves, 1 and Anna, 0. We went snorkeling after that and I saw a shortnose batfish! It was one of the weirdest things I have ever seen. I also saw a little barracuda, so many sponges, and many starfish. No stony corals. This is because we were in mangrove territory.

We loaded back up on the boats and headed to Belize City. I fell asleep in the sun and consequently have a light burn all over my arms and back. We ate at Calypso again and then headed to the airport. The flight was fast and before I knew it, we were all saying goodbye. I felt pretty sad but that’s only because it was such an awesome trip with awesome people!

Last Day?

I’m sitting in the pleathery seat of a Southwest flight. It’s certainly strange to not be spending the day in the water. We did this morning, but now, not even being on land, but catapulted into the air, is discombobulating.

This morning’s snorkel was my favorite of the entire trip. We took the boat out with our two amazing tour guides (Herbie and Javier) to Twin Peaks. This is the name of a caye that is made up of mangroves and is separated into two pieces by a sea inlet. We walked through a portion of the land. This was quite difficult due to uneven ground hidden under a layer of seawater. We were falling into holes left and right. I fell in one that went all the up to my mid-thigh.

The best part, however, was when we got to snorkel through the inlet. I was shocked as to the community complexity that was happening on the roots of the red mangrove trees. (Unfortunately, the reign of the soft corals was over. I didn’t see any today.) The sponge symbiosis was so obvious. It was amazing to see something that was mentioned in both a taxonomic briefing and a topic lecture actually flourishing out in the field. The fact that the mangrove is an understudied ecosystem makes me even more interested in it. What if I end up there, studying evolution?

Our other stop of the day made the idea of continuing my studies out in Belize that much more attractive. We visited the Smithsonian research station. Despite being on an island that is only an acre, the facilities were beautiful. I can definitely see myself returning in some capacity. At the same time, there is so much of the world to be examined under the lens of evolution.

 

Wrap-up

The rainforest and the coral reef ecosystems are so different yet so similar. For example both ecosystems are actually relatively low nutrient environments, yet both foster mind boggling biodiversity. All the primary producers are geared to maximize the limited amount of nutrients they have access to. The cecropia trees in the forest grow thin and tall to get through the canopy. The corals in deeper waters grow flat and wide to get as much of what little sun reaches through the abyss.

One of the differences I noticed is that in the forest the primary produces are very abundant and in your face, it takes a little more effort and attention to detail to notice all the things it supports. Whereas in the water the primary produces are less apparent. It takes some careful spotting to sea the macro-algae growing on the sea floor, and you can’t even see the micro-algae that contributes so much to bringing nutrients into the system. But it’s very easy to spot the extremely wide variety of animals supported by these microscopic plankton. This is actually quite different to what I was expecting. I thought I would have see more animal life in the forest, but I felt like I saw more animals in the water. Mainly because sea creatures seem a lot less shy and let you get a lot closer before they skitter away.

My favourite part of the course on land was the the bird watching. It’s a little surreal to wake up before the birds and sun. I feel like birds are the fish of the air. They can go anywhere they want. They seem so free, I’m jealous. The best part of the reef portion was the snorkel at the fore reef. I finally got better at diving, it’s so fun to go down and look at the coral and try to chase the fish around. That spotted eagle ray was insane as well. My least favourite part of the course it that everything else I do in life will seem bland and pale in comparison to these past two weeks. Thanks Scott and Adrienne for ruining the rest of life for me (totally kidding). I honestly loved everything about this. Even the tick and sea flies, it wouldn’t be real without them.

I think the biggest take away for me is that these ecosystems are fragile and needs us protect them from ourselves. And it not just help from biologist or conservationists. Everyone can and should play a part. You don’t have to biologist to be more careful with your trash. You can be a geologist and still help run research stations. You can be an engineer and improve the infrastructure and equipment to aid biologist. I hope I can remember this lesson for the rest of my life and keep playing my part.

Day 15: Who is Carrie Bow?

Last day of the trip. I don’t want to leave, there’s a lump in my throat. We got packed breakfast because we were leaving Middle Caye at 7. I ate mine immediately. The first thing we did was take the boat to another island called Carrie Bow Caye. On it was another research station. The island itself was smaller than ours but their facilities are more geared towards research. It was run by the Smithsonian Institute. The stations managers Clyde and Liz took us on a quick tour. I learned that you can volunteer to be a station manager for 4 weeks at a time. Maybe I can come back here as a volunteer. Who knows. But I sure hope so.

After the tour we went to another set of islands called Twin Cayes. The two mangrove islands was separated by a channel. We snorkeled up and down it to look at what was hiding in the mangroves. I saw a couple sea stars and some ginormous feather duster worms, but that was about it. I didn’t get to see a Mangrove crab in its natural habitat. Other people said they saw a barracuda. Getting out of the water for the last time sucked. We got back into the boat and we were off. Back to Belize City, then back to Houston.

“This land is unbelizeable, you gotta see it to belize it.” I hope I’ll see it again.

Return to Civilization

DSCN4436
Smithsonian research station at Carrie Bow Caye.

Our final day in Belize dawned bright and early, as always. With sandwiches and snorkels in hand, we said our final goodbyes to the palm trees and composting toilets of Glover’s Reef and made our way out of the atoll. Our first stop before Belize City was Carrie Bow Caye, a Smithsonian research facility housed on a speck of an island in the Caribbean. We were able to meet a crab researcher that’s been studying the incredible diversity of Belizean reefs for over 30 years at Carrie Bow.

We then stopped at Twin Caye, an aptly named mangrove island that’s split in two by a channel. We first walked and then snorkeled through the muggy mangroves, carefully picking our way through their stilted roots. Mangroves may just look like odd trees from above the surface, but underwater they’re an important habitat for sponges and act as fish nurseries. I wasn’t able to identify any herbivorous fish species, but the mangrove roots were swarming with tiny juvenile fish for this reason. I even saw an adorable baby barracuda! (I think this trip has given me a new definition for cute).

And with that, we were off to the marina in Belize City. After an incredibly long lunch at the infamous Calypso restaurant, we made our way to the airport. Before I knew it, we were waving goodbye to this beautiful country, several bottles of hot sauce heavier than when we arrived.

Shenanigans on Airplanes

Sadly, today was our last day. We set out from Middle Caye at 7am and stopped at two other Cayes on our way back to Belize City.

The first Caye we stopped at was Carrie Bow, which is a Smithsonian Institute research site. It’s a super small island near South Water Caye, and it’s beautiful. They gave us a tour and we got to talk to a crab researcher who has been working there almost since they opened in 1972.

The second Caye we stopped at was Twin Caye, which is a mangrove island split down the middle by a channel. We walked in the mangroves and I got to see the pores that the red mangroves use for getting oxygen. We also got to see the yellow leaves that the mangrove diverts salt to in order to save the rest of its leaves.

After walking in the mangroves we snorkeled through the channel. I sadly did not see any sea hares, but I did see some clams on the mangrove roots. I also saw the sponges that mangrove roots have a symbiosis with, a whole ton of baby fish (mangroves are fish nurseries), some magnificent feather duster worms, and a huge barracuda. The barracuda was hiding in the roots of a mangrove and I almost didn’t see it until I was basically right in its face. It flashed its teeth at me as I backed up.

After the Cayes we had our last meal in Belize at Calypso. They took a predictably long time, but it was still very tasty having fresh fish while looking out at the ocean it came from. Our plane ride was short and bittersweet, and although we had to sit on the tarmac for awhile, it seems like our curse of terrible transportation has been defeated.

I’m sad to be going, but I’m sure I’ll be back.

Day 15: Farewell, Belize

This morning we bid farewell to Glover’s reef. We then took the boat to Carrie Bow, a nearby Smithsonian research station. There was a couple living at the station for the month as managers, and apparently it’s relatively easy to land a volunteer station manager position at the station. That sounds like an awesome way to spend a month.

Next, we went to an island completely covered in mangroves. We walked a little ways through the island and saw lots of young fish using the mangrove roots for protection. We then snorkeled around the island. The water was pretty murky, but I did find some sort of branching, calciferous red algae covered in sediment. I didn’t want to dive down to look at it because the seafloor was also covered in upside-down jellyfishes that flip over and bob around when you kick too close to them.

I am on the plane, flying back to Houston. It’s hard to believe that in just a few hours I will be in an air-conditioned home, take my first warm shower in 2 weeks, and change into clothes that were washed in a machine instead of a sink. This will definitely be nice, but I can’t say I’m super excited to return to the city. Belize is such an amazing country and I can’t wait to return some day.
