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.

(Nakian) May 31: Mangrove x Return

DSCN2692

The morning was a busy one, summarizing the two weeks trip with undoing all the luggage and reorganizing them according to the last day’s plan. All the cloths I have wore bore the memories of the parts of forests and reefs I have seen with. I couldn’t believe a chapter of my life is coming to an end. We set out into the ocean early in the morning. We stopped at Carrie Bow Caye where the Smithsonian Institute Research Station was situated. There on a 1.5 acre island stood cozy station where we heard about a retiring ecologist’s story. After that we continued on to our last ecosystem: Mangrove. The mangrove is a peculiar place where plants have engineered islands on sea water. It would have probably a small patch of island where mangroves started to grow. However as their high roots caught silts and their literfall accumulated, they expanded the island and host a immense biomass. School of juvenile fish swam among the eerie roots covered with sponges. I tried to look for brown algae but the mucky water made it hard. I couldn’t find one.
On the way to Belize City, we passed by a small island dominated by some trees and flock of frigate birds. Someone explained that it was their nesting ground that shrunk year after year because of rising sea level and hurricanes. The island was a fortress with small threats. More so the fate of the island made me sad.

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.

Day 15: Mangroves and leaving Belize

This morning we packed up our things and very sadly left Glovers Reef. Watching the paradisiacal island grow smaller in the distance, the only thing that lifted my spirits me was the realization that soon all of my bug bites will grow smaller as well. On our way back to Belize City, we first stopped on Carrie Bow Cay, an island of about 1.5 acres that is home to a Smithsonian research station. Our tour of the facilities had everyone wishing that they could do research or be a volunteer station manager there in the future. It was also sobering, though, because the current station managers mentioned that the island has lost considerable land due to rising sea level. The island also lost its population of mangroves, which increases the rate of erosion. On top of normal rates, hurricanes are particularly destructive because of the high wind and wave action that they entail. On the current trajectory, Carrie Bow Cay may disappear before we are able to go back. Seeing the island put climate change into perspective for me. Rising sea levels are something we hear about, but it’s difficult to imagine an entire island ceasing to exist until you have seen it in action.

Our next stop was Twin Caye to visit mangroves and view the diversity that they hold. Mangroves are an important habitat for young fish because of the protection that they provide. As mentioned above, they also prevent erosion and even create land. In one area we were able to walk between mangrove trees in the soil that they had created. It smelled pretty bad and there were a fair number of sinkholes, but it was cool to see how productive the trees are.

Afterward, we put on our dive skins, masks, and fins one last time to snorkel next to the roots of the mangrove. The sandy bottom was home to hundreds of upside down jellyfish which sit on the sea floor with their bell to the ground and their tentacles raised to the surface. When the water around them is disrupted they start to float around, so we had to be careful not to disturb the water around them. We also saw a number of sea stars that were at least a foot in diameter. I don’t think I had ever seen live sea stars that were that big. Additionally, the sea floor was home to Caulerpa sertularioides, a species that has very feather-like branches and prefers to live in sandy areas and near mangroves. I hadn’t seen the species yet, so I’m glad we got a chance to visit the mangroves.

It was also amazing to witness how much life the mangroves supported. All of the roots were covered in species of algae and sponges that provided even more habitat for fish and other animals that flitted between the roots and lived in the sheaths of biotic material around the roots.

When we were done with the mangroves we packed up all of our dirty and wet clothes and made our way back to Belize City. Getting through the tiny airport was relatively easy. It’s weird being back in the U.S. with so many people and so much activity everywhere. It will be strange not eating rice, beans, and chicken for almost every lunch and dinner.

Day 15: Home bound

We’ve packed and left Glover’s to perform one last tour of the Carrie Bow Cay and a final dive in the Twin Caye mangroves, a habitat with unique saline-tolerant trees that not only serve as a great fish nursery from many ocean fishes, but also as a carbon reserve that takes more CO2 from the atmosphere than many other tree biomes, making their conservation a priority. While the insides of mangroves are oxygen poor and harsh, the edges of a mangrove forest harbor diverse life forms ranging from sponges, to juvenile fishes, to magnificent feather duster worms, and most importantly to me, jellyfishes.

The mangroves are carpeted with two species of jellyfish: Cassiopea frondosa and Cassiopea xamachana. These guys are also known as upside down jellyfishes, since they orient their tentacles upwards to energize the photosynthetic symbionts that live in there, similar to how corals foster photosynthetic algae in their polyps. These symbionts give each jellyfish a different color, ranging from yellow to orange to even green. With the hundreds of jellyfishes that lay on the sea floor, it was almost like a carpet mosaic. Adrienne, one of our instructors this trip, wondered why more jellyfish hadn’t adopted this kind of lifestyle, considering how numerous and successful the upside down jellyfishes were. We also wondered whether these guys could be a transition between sedentary polyps that have symbiotic algae and free-swimming jellyfishes that feed on prey. I need to brood on these questions for a bit, but I’m not sure I’ll find an answer to this evolutionary problem.

For now, I need to consolidate my thoughts on the fact of leaving the country. I’ll make sure to update you all on my final thoughts and musings. Definitely felt a lifetime pass in just two weeks and can’t wait to share all the pictures!

Mangroves + Goodbyes

Hello everyone! Once again, the sunrise was unbelievably (or should I say unBelizably?) beautiful and the perfect way to begin our last day in Belize. We left Glover’s Reef early this morning and took a boat out to Carrie Bow Cay Marine Field Station. It was a cool place, but learning that global climate change could lead to rising water levels that could make the island disappear completely made me sad. During a quick tour of the quaint research facilities, I saw quite a few echinoderms that had been dried or preserved. Most notably, there were some slate pencil urchins (Eucidaris tribuloides) and a large red heart urchin (Meoma ventricosa) along their balcony railings.

We then headed to Twin Cayes to snorkel among the mangroves in the channel that gives the islands their name. The waters here were really murky, with lots of loose sediment that was easily kicked up by our fins, so it was a little hard to see at times. However, I did identify several large bright orange cushioned stars (Oreaster reticulatus) lying in the sand near algae patches. It was fun to be able to hold them and feel the short knobby spines on their dorsal side. Too soon, our last snorkel in Belize was finished and we climbed back aboard the boat to ride to Princess Marina.

Lunch at Calypso came to an end all too quickly, and then came time for us to say goodbye to our three wonderful marine safety officers who had assisted us every time we flipped our fins in the water (and with much more on land as a matter of fact). Sitting here now in this Southwest airlines plane and staring out the window at the green-blue ocean outside, it’s hard to imagine that more goodbyes to the amazing students and professors who I’ve spent the last two weeks with are rapidly approaching. A lot has happened these past couple weeks, and I wouldn’t have wanted to spend them with any other group of people. Check back in tomorrow for my final recap and reflection. 🙂

Wrap up

One week in the Rainforest. One week on the coral reef. As different as the two ecosystems sound, in a lot of ways they are similar. Both are hotspots for biological diversity, driven by diverse geography and topographical features which create countless niches to be filled. The niches are filled in fact by huge ranges of organisms that have adapted to suit their microenvironments. For example in both the rainforest and in coral reefs, light penetration plays a role in determining the organisms that will survive and thrive in different locations. High light-need species reach the heights of the canopy in the rainforest; they reside in shallow waters on the reef. Other factors include resilience in inclement weather, particularly in countries like Belize. Belize is affected by tropical weather systems such as hurricanes, which may reshape the ecosystems and the organisms that are not sheltered must be able to survive the effects. This is true in both the forest and the reef, as exposed species in either are at risk.

Another similarity I have noticed is the apparent paradox of high biological diversity in spite of nutrient poor environments. Both reefs and forests support incredible richness and abundance of life. In nutrient poor environments this is made possible by the efficient cycling of the nutrients that are present. In fact, the ecosystems themselves are in a way nutrient rich, in that the nutrients are usually actively being used by the occupants.

This course was what I expected, but better. I had expected to find a bit of direction and to maybe make some friends. I have found such reassurance in this course: reassurance of wanting to pursue biology and perhaps marine biology in particular. And the group of people on this trip are each individually important in creating the amazing group dynamic we had. This also includes the instructors, who are passionate about the material and make me feel passionate about it as well.

My favorite part of this trip was snorkeling the fore reef. I remember letting myself bob in the waves and then someone pointed down. There was a huge spotted eagle ray swimming right below us. Seeing something like that in its natural environment was incredible. My least favorite part of this trip was the itching. Between chigger, tick, sand fly, and mosquito bites, there are more bites on me than I can count. Incidentally I apparently also have a fairly strong reaction to most of those bites. I have never before woken up in the middle of the night due to itching so badly.

Things I have learned:

  1. Sometimes it is easiest to believe that there is a simple right and wrong, but that’s hardly ever the case. This trip reminded me of that. It would be nice to say that all poaching is inexcusable and conservation should be the easy answer. That, however, is not the world we live in. Hearing more about conflicts between Guatemala and Belize have reminded me of that. I’m going to try very hard not to forget it.
  2. I know that in pursuing science, sometimes the answers we end up with are not the ones we want to hear. I will not always be correct. In fact, most of the time I will probably be wrong.
  3. There are a lot of things worth trying to save in this world. I cannot save all of them. I am not in control. So I am going to try and save a small piece of it.
  4. [Bonus] Ocelots/jaguars/a-lot-of-animals sound really wierd

Thank you.
