Welcome to the jungle (we’ve got tapirs and jaguars) (15/06/22)

I’m actually so sad to leave Glover’s Reef, I miss the hermit crabs, the iguanas and lizards, the giant blue crabs, the breeze, I even miss the sand everywhere and maybe even the mosquitos. We said our goodbye’s to Glover’s this morning, I can’t believe that was still today!

Then got back on the boat to Belize city. I slept through most of the boat ride, even the bumpier parts, but it wasn’t anywhere near as bad as the first ride into Glover’s. I also got to eat some of the candy I bought back when we first got into Belize, some chile and chamoy lollipops, (I bought some more sweet and spicy candies when we went to the store again today). We had a long and relaxed lunch at Calypso, right on the dock where we got off of the boat. Then set off to the Belize Zoo and education center. I unfortunately did not see any of my taxon today. My rainforest taxon is lichen and fungi! Both pretty interesting but super hard to identify specific species or even classify in some cases!

Also yesterday on Glover’s we got to eat Lionfish ceviche! It was so good, I’ve never had ceviche until now and I think I’ve been missing out. I don’t know if it’ll taste as good without the fresh caught lionfish. We also had conch at dinner, it’s common to eat here in Belize but I’ve never had it before, and it was pretty good! I’m not a huge fan of seafood so I’m glad it was fried and had a relatively light flavor and a nice texture.

We also got a night tour of the zoo here after dinner. They only have animals native to Belize and all of them are rescues, either from people keeping wild animals as pets then dumping them when they get too big or aggressive, or were going to be killed for hunting livestock by farmers, or brought in as infants that wouldn’t have survived otherwise.

I think my favorite was the Tapir, his nose was just so long and funny and kept wiggling around!

Tomorrow we have another long travel day, but hopefully it’ll be just as much fun!

Day 8 – Meeting a Tapir!

Today we started our time on land! While most of the morning and early afternoon was spent traveling from Glovers Reef to inland Belize, this evening we got to hear a very interesting lecture and visit the Belize zoo after dark to see the nocturnal animals. (Side note: We learned today that the Dramamine we took for the forereef boat ride was actually just ginger pills, so that’s why it didn’t work at all, luckily I had real Dramamine for today.)

We heard about Scarlet Macaw’s nesting and habitat selection from a scientist named Dr. Boris. He focused a lot on the functional aspect of science (researching in order to conserve nature) which I found very exciting! Aside from a wealth of knowledge about the Scarlet Macaw, he also gave us a lot of good advice on being a researcher and the difficulties it sometimes presents.

Also, I figured out pretty quickly that you need to keep an eye on where your walking at night, as leaf cutter ants are nocturnal and we saw a few large lines of them hard at work right across our path! Snakes are also a good thing to keep an eye out for late at night.

After dark, we got to go on a night tour at the zoo! Here I was able to meet a Tapir named Indy (who loves carrots).

We also saw a lot of predatory cats which was super cool! Since it was night (and our guide Carlos had chicken livers) they were very active. We met a jaguar, that had been trained to roll over, as well as an ocelot, puma, and margay.

I also saw the first individual from my jungle taxonomic group today, a tiny brown moth I had no hope of identifying! I am looking forward to seeing more moths/butterflies over the next week that I will be able to identify (and I’m sure many I wont!).

We ate what??

There was a lot to do today, since it was our last day!

We started out by going to a non-MPA to collect our last data set for our research question from three days ago. We used the transects and quadrats for the last time, which was very bitter sweet. The reef was very sparse, with very few live corals. There was a decent amount of brown algae, mainly the saucer leaf algae, covering the rubble. We saw some Caribbean reef squid though! There were six or seven of them, and they were all in a row in the seagrass bed that surrounded the reef. Doing what, I don’t know.

Afterwards, we went to a reef in the MPA, which they call “The Aquarium.” There were tons of fish, including parrot fish, angel fish, damsel fish, and others that I couldn’t identify. There was also a lot of brown algae! Yay! It was mainly saucer leaf algae and funnelweed, intermixed with some white scroll algae and y-branching algae. I saw a really cool blue variety of the y-branching algae, which I believe to have been dictyota menstrualis. It was right in the middle of a patch of saucer leaf algae.

After lunch, we compiled and analyzed our data, and presented it to the professors. You can read about it below! The poster doesn’t include in the discussion that there may have also been a difference in the non-MPA sited due to environmental factors that we couldn’t take into account, such as differences in the amount of fishing in each area.

We enjoyed some presentations from our fellow classmates, and then had a lovely dinner, which included friend conch! It was actually quite tasty. But it wasn’t until after dinner that the real fun began! We performed dissections on the three lionfish that were caught by Prof Solomon this week, and added our data to the list of lionfish data from the previous years of the BIOS 319 trip. Once we were done, Prof Solomon filleted the lionfish, and put them into a mixture of lime juice, tomato, and onions to create a ceviche. It turned out quite delicious! I would definitely recommend eating lionfish! Although I think I still smell like fish.

Anyways, today was the last day on the reef! It’s amazing that the time passed so quickly! Tomorrow we will be taking a boat back to the mainland, and starting the land portion of the class. See you all then!

A Grand Finale

Today we finally finished our sea urchin/coral health correlation study. Unfortunately the last reef we surveyed was not the healthiest, with very little reef structure or live coral. However, there were Sooo many urchins. We collected over 170 of them. I remember turning over a rock and seeing both the rock and the sand  under it simply covered in urchins. I had to get someone next to me to come help me collect them because I couldn’t carry them all.

We also saw reef squid for the first time. There were seven of them right off the boat, and they seemed to be all in a straight line in the middle of the water column. I didn’t see any new species of green algae, but I did see some very unique looking individuals. One was a a green bubble algae (dictyospaeria cavernosa) that looked way more yellow than any I had seen before. When I lifted it up it looked like the inside of the bible had been completely filled with sand!

I also saw a Ventricaria ventricosa (sea pearl) that looked like a deep shade of blue that really stood out from the dark green I usually see. I am not sure what caused this appearance but it was really pretty!

When we finished collecting and analyzing our data, we found a that more sea urchins were correlated with a lower percentage of coral cover being alive. However, our conclusion was highly suspect as for example, we got better and better at finding urchins each time we collected data.

Finally, at the end of the night we dissected the lion fish we had speared over the course of the week. It was a little gross, but it was also really cool to open up the stomach and find the little fish the lion fish had been eating still inside!

Day 7: Ending our Last Day at Glover’s with Lionfish Ceviche

We went on our last snorkeling trip to collect data from a non marine protected reef. There is saw a significant amount of bladed fire coral. I also saw a Christmas tree worm that appeared to have bored inside of fire coral which I thought was very interesting because I thought, since fire coral was an athecate hydroid colony and a hard coral, many marine organisms would avoid them due to their stinging capabilities, but they seem to support many life forms.

I also saw and photographed this Caribbean Reef Squid which was very cool! I saw some color changes on the squid when two were together so I wonder if they were communicating.

 Later we dissected three lionfish ( named snack, appetizer, and main course). Our group dissected snack the smallest of the three. After collecting data we made our lionfish into ceviche dish! Muy delicioso!

Although I am sad to leave Glover’s, I have grown and learned so much. I’m so excited for the rainforest and to stay at Las Cuevas!

Last Day on the Reef!

Hey y’all! It’s Michiel again : )

I’m sure you guys already know that the day started with everyone waking up and getting breakfast by 7. After waking up this morning and getting breakfast, everyone quickly put on their snorkel gear, got their transects, quadrats, and clipboards, and boarded the boat to go out to a non-MPA reef. There, we collected data for the research question I talked about on June 11. The reef was a pretty good depth, not to shallow or too deep, but it had a lot of fire sponge and fire coral. Thankfully, I managed not to touch any while I was there. It also had a lot of dead coral and there were very few fish. I remember seeing two Cocoa Damselfish (Stegastes variabilis), but I can’t remember seeing any other fish I could identify. After, Ava and I laid out our transect and counted alive and dead coral in our quadrat, the entire class began collecting sea urchins for 10 minutes. This place was full of sea urchins; I ended up getting 11, but some people were able to find a lot more. We ended up with 177 sea urchins after only 10 minutes.

After this reef, we went to a much nicer, deeper reef where the class had a chance to snorkel without the pressure of collecting any data. This was our last time to snorkel on the trip, and I’m really happy with the reef they ended up taking us too. The coral in the area was beautiful, and I saw so many fish. In terms of herbivorous fish, I saw a bunch of Cocoa Damselfish (S. variabilis), some really large Sergeant Majors (Abudefduf saxatilis) – they were about 20 cm – Threespot Damselfish (S. planifrons), and Bicolor Damselfish (S. partitus). I also saw a Blue Tang (Acanthurus coeruleus) and a male Bluelip Parrotfish (Cryptotomus roseus), both of which I followed for a while to get a good picture. I got some fine-ish pictures of the Blue Tang, but I couldn’t get any good ones of the parrotfish because the parrotfish kept going all over the reef, moving through coral so fast that I could barely keep up with it. All of these fish were really hard to get pictures of because they tend to hide within the coral whenever you approach them.

After we left that reef, we compiled all of the data we’ve collected over the past couple of days. We were able to conclude that there is a correlation between a high percentage of live coral coverage and less sea urchins. However, we didn’t see any correlation between the amount of urchins and whether we were collected at an MPA or a non-MPA. We think this may be due to our ability in collecting sea urchins improving as we went from reef to reef. This would explain why we collected so few sea urchins from the first non-MPA site we went to, which probably skewed our results. After determining all of this, we put all of our information on a poster and presented our project to Scott and Adrienne.

Later in the day (after lectures and dinner) we dissected lionfish. My group was given a really tiny lionfish, which was challenging, but my confidence in my dexterity skills skyrocketed after I saw how well I did on the dissection. The most interesting part of the dissection was opening its stomach to examine its content. We were able to see some invertebrate organism within it that measured about 2.1 cm. After dissecting the fish, Scott took them, fileted them, and made ceviche. The ceviche was delicious, and we were all happy that we were simultaneously having a wonderful snack and contributing to the betterment of our marine environment.

After the ceviche, we worked on our assignments and got ready for bed. This was the last day of the reef! I’m sad it’s over – I had so much fun snorkeling – but I’m excited for everything I’m going to learn in the rainforest.

The Last Day at Glovers (Day 7)- Ending with a Lionfish ceviche “feast”

Caribbean reef squidToday was our last day on the island :,( we did our last snorkel this morning, and tomorrow we head back to the mainland for the second half of our expedition. Each day feels like many, but then the week passed in the blink of an eye.

At 8:00AM, after breakfast, we suited up for the last time in our snorkel gear to head out on a mission to collect our last data point in the ongoing TFB research question: what is the association between live coral cover and the abundance of sea urchins on patch reefs within and outside of the Marine Protected Area of Glovers Reef Atoll?

We headed to the second non-MPA patch reef for our last transect/quadrat data collection. Our last reef science hurrah. Scott caught one more lionfish (making 3 in total of the invasive species soon to be ceviche). After our data collection was done, we went to one more MPA reef within the atoll for one last free snorkel. While the wind and waves were intense, it was a nice experience. I came across a handful more queen conchs (Strombus gigas), one milk conch (Strombus stratus), and one Amber penshell (Pinnea carnea). Everyone but me it seems got to see one or multiple Caribbean reef squids (Sepioteuthis sepioidea).

We made a poster with our analyzed data (see picture), and then after lunch, I presented my taxon lecture on mollusks (on the last day, after we’d seen all the mollusks we could have possibly seen). For dinner, they had fried conch, meaning I got to taste my taxon! It tasted like crab cakes ¯\_(ツ)_/¯

Fried conch

After dinner, we dissected the 3 lion fish we had collected through the week, identifying the sex, weight, length, and last meal. (Ours was named appetizer)! And then Scott filleted the fish and we ate them as ceviche. It was my first time trying ceviche, and it honestly just tasted like lime. Would eat again!

This time on the island was honestly remarkable, and I can’t wait for the rainforest half of the trip (although I can’t see how it could be better than this)

 

Day 7: Predator Turned Prey

From our last snorkel to lionfish ceviche, today was a great day overall. We started off by heading to our final patch reef to finish collecting data on the relationship between coral cover and sea urchin abundance. The wind and waves were strong, but overall, it was a fairly smooth experience. However, the boat ride was more akin to a rollercoaster. The relationship between urchins and live coral was an interesting concept to investigate. Our data reliability may be a bit questionable (as we are far from experienced in this type of research) but the patch reefs we visited all had significant growth of brown algae, which colonizes the dead stony coral skeletons along with a multitude of other organisms. The battle between stony corals and macroalgae is constant, yet it’s clear that human-driven environmental factors have swayed many reef regions in favor of more prolific algae growth at the detriment of stony reef builders. In theory, this may bolster the local urchin population because of an increase in available algal food.

That doesn’t mean these reefs aren’t teeming with life though. I was able to see several colonies of Orbicella faveolata (some with small fish resting on the surface), tons of Porites, and even several Caribbean reef squids.

We ended the night by dissecting the invasive lionfish we caught over the past few days and then turning them into ceviche. A tasty snack to end a wonderful time on the island. I look forward to the forest, and hopefully the opportunity to spot an amphibian or two.

Day 7 – Triggerfish sighting and Lionfish ceviche!

Today was our last day on the reef, and we made sure to pack it very full! This morning we took the boat out, on relatively choppy water, to two patch reefs. On our first patch reef I saw a giant trigger fish! It was around 12-14” long and oval shaped. I also found a ton of sea urchins in a pile of empty conch shells (these had probably been tossed back into the water by fishermen).

On the second patch reef, I saw lots of soft corals interspersed with large sponges. In some areas there were common sea fans along side these sponges, and in others there were more branching soft corals (probably slit-pore sea rods or porous sea rods). This was interesting, as in other areas I saw the sponges more alongside hard corals and less bunched in with soft corals. This makes me wonder if sponges and soft corals compete a lot for space, or if one group outcompetes the other most of the time! (Seeing as there are so many soft corals, I’m guessing they usually win)

After dinner, we were finally able to dissect the invasive lionfish that Scott speared this week, and turn them into ceviche! My group dissected the smallest lionfish, which was pretty difficult as all we had was a large pair of blunt scissors and a set of forceps. However, we were able to identify our fish as an immature female, and identify its stomach contents; an invertebrate fish!

Excited to head to the jungle!

A delayed post- the forereef: 1, Jazmine: -100

Spoiler alert: no mollusks were found this day (Monday June 13, 2022).

 

As is indicative of me posting this a whole day later, yesterday had me out for the count. I became over confident, so trusting in myself and a  single Dramamine tablet’s ability to keep me safe. I was oh so incorrect.

At 7:00AM, we showed up to the dining hall for breakfast, as usual. It was a windy night, followed by a windy morning. We were all aware of this, but this was our last chance: we had to make it to the fore-reef that day, or else we weren’t going to. So I popped a Dramamine, and hoped for the best, as did the rest of the crew.

Come 8:00AM, we were geared up and hopping on the boat to head for a break in the reef crest, going to the full wave action of the ocean, whose energy wouldn’t be broken by an atoll of coral. The change was immediately noticeable when we passed the crest, both in wave size and in the state of my body’s well-being. As the sea began to churn with boat sized waves, so did my stomach. No turning back now.

We continued onward to a spot at which coral should be visible at the ocean floor, but that would be significantly deeper than anything we’ve experienced so far. We ventured to the drop off point, the place where the bottom dropped from 60 ft to over a hundred. With half of the team already feeling seasick, we hopped into the water to begin our activity, to experience the fore reef.

 

And I must say, it was magnificently stunning, deep blue water at a depth that made the whole world feel small, with comb jellies swimming right below us en mass, and a giant sea turtle resting at the bottom of the sea. It was an experience like no other, and I wish that the sea had been calmer or my body better acclimated so I could enjoy it to its full degree.

comb jellies! (picture courtesy of Phoenix)

But alas, each time I popped my head above water, my entire being would return to the fact that the sea is not my friend, and that the world was in fact churning. As quickly as we got there, we loaded back into the boat, a little worse for the wear, but having experienced something awesome.

When we returned to our island, I laid on the dock for an hour, simply trying to be able to stand without having the overwhelming feeling of needing to vomit. The sea bested me. It won. When I thought I was better, I went onward to watch the day’s lectures and then to lunch with the rest of the team. This is when I started to realize that it wasn’t done with me yet, the sea sickness. No, it had me in its grips. Even after 2 extra strength Tylenol during the lectures, I had to stop chewing at lunch because my body and my head rejected it: the headache was beginning. By the time we got to the planning stage of our next activity, a beach cleanup effort with an added scientific approach question, I couldn’t lift my head without it hurting, nor wear my glasses, and the world was so bright, even when I borrowed sunglasses. A migraine had hit. I felt so bad abandoning my team, but the professors understood and told me to go and lay down, which I truly needed.

I returned at dinner, still not feeling 100%, but at least able to walk around and be there. I didn’t return to my full capacity until the next morning, after a full night’s sleep ushered along by 2 Dramamine. I don’t know whether to say I learned my lesson, or to say I’d still do it again, just better prepared next time. I guess time will tell

During my time of rest, the rest of the TFBs were so productive and did so good: they collected more than 60kg of trash off the beach’s of the Middle Caye (our island), over 80% of which was burnable on site. They also created a poster with this data (see picture), which they presented to the professors. So proud!
