First Day of Experiments!

Leave a comment

Hey guys! It’s Michiel; I’m glad to write to y’all again : )

This morning I woke up and had an amazing breakfast (as always here). After breakfast, Adrienne and Scott wanted us to practice using our quadrats and transects, so they sent us out to collect some data on the island using these tools. Ava and I decided that we wanted to see how much of the island sand was disturbed by crab lines. We set up a 50 yard line from our transect, set our quadrat on either side of the transect, and counted the amount of squares covering sand that was disturbed by crab lines. We ultimately determined that about 9% of the sand in the area we studied was disturbed.

After this riveting experiment, we got to put our tools to use out on the reef! Our professors left us in the wet lab with only instructions to come up with a research question and methodology. As a class, we asked “How does the density of Penicillus green algae change as we get further from the dock?” To test this, each buddy group lined up in the water near the dock and spread out horizontally so that there was at least 10 ft of space between us. Then each of us went off, placing our quadrats at every 10 foot marking on the transect to count the number of Penicillus organisms. Unfortunately, Ava and I did not see a single one (we did see two sea anemones and a starfish, though). We also did not get to see any herbivorous fish since we stayed pretty far away from the patch reefs : (. They’re really only found over there because their diet consists mostly of algae that grows on the reef, so it would be unwise for them to go too far.

Thankfully, the other groups did find some Penicillus, so we pooled our data and determined that the organism increases in density as one goes further from the dock. We believe that Ava and I did not see any because the lush sea grass in our area may outcompete or cover it.  After discussing our results, the class put together a poster and presented our research to Scott and Adrienne.

After these presentations, we went to a very cool area of the island that was just a huge fossilized coral reef. Adrienne showed us lots and lots of different, very well preserved, corals. She identified some of the most common corals we have been seeing in the reef and told us about their importance and history. She even showed us a couple species that are currently rapidly dying off in coral reefs.

After the fossilized coral area, we had a presentation, then dinner, then I presented on herbivorous fish (I hope you all enjoyed), then there were a couple more presentations.

Overall, today was full of activities and it was our first time conducting research in the water! We all had lots of fun and I’m sure we’re all excited for the upcoming days of research in bigger coral reef systems.

Also, here’s a picture Ava took of me holding a starfish (thank you Ava!)

First Reef Day!

Hey y’all, It’s Michiel again : )

Today was so much fun! This morning was absolutely beautiful and I loved looking out over the island during breakfast. Just after breakfast, we saw an iguana. It was very pretty and we kept seeing iguanas (or perhaps the same iguana) throughout the day.

After breakfast, we put on our snorkel gear and dove off the dock. The tropical waters were very inviting with how warm they were. We saw huge schools of tiny fish which we could not identify. Once my partner (Ava) and I made it to the patch reefs, we could not get enough of our taxonomic groups. They were telling me all about soft corals and I returned the favor by offering them  facts about herbivorous fish. In this reef, I saw a lot of herbivorous fish, but I didn’t have my taxon ID sheet so I was only able to identify a few. We definitely saw a lot of Threespot Damselfish (Stegastes planifrons) and Cocoa Damselfish (Stegastes variabilis), and I believe we may have seen an Ocean Surgeonfish (Acanthurus bahianus). I noticed that it’s really hard to get good pictures of a lot of these fish because they hide as you approach, so I stayed a good distance from them and zoomed my camera in as much as I could.

Once we got into the water, we went to the wet lab to make quadrats and set up a scavenger hunt. Soon after this, we decided to explore the reef near a different part of the island, but to access that area we had to go through the Mangroves of Death (MOD), which were filled with mosquitos that chased us and bit through our lycra dive skins as we ran through the forest. Finally finding safe haven within the water, Ava and I went off again to look at more soft corals and herbivorous fish. While there, I saw many Sergeant Majors (Abudefduf saxatilis) and Beaugregories (Stegastes leucostictus). We also saw a lot of competition between corals, and we saw two stingrays! Ava and I were very grateful that we had decided to swim over the seagrass instead of walk through it when we saw those.

After this second reef excursion, we had wonderful presentations given by Rusty, Ava, Maegan, Phoenix, and Michael who presented on hard corals, soft corals, coral reef framework, ctenophores and jellyfish, and sponges respectively. Now, the day is over and I am posting this blog before getting some rest.

Also, I’ve included a group photo of some of other TFBs and I hanging out in the wet lab! See you guys soon!

Day 1: Longest Boat Ride Ever

5 Comments

Hey, guys! It’s Michiel again. Today was our first day in Belize, so I’ll try to quickly tell you guys all about it.

I woke up bright and early at 5:15, got an uber to campus, and was with the rest of my group around 6 am. Together, we took a bus to IAH, which was packed, and successfully made it to our gate. Before boarding, a few friends and I picked up Panda Express (a great way to start one’s day). The flight itself was actually very fast, I spent the majority of it sleeping and reading. Once we landed and were ready to leave the airport, we took a bus to a grocery store, where I bought a souvenir water bottle and pingüinos. After this, it was finally time to take the boat to our research station. The boat ride was four hours, and the weather was extremely hot and humid, but we were all entertained with the changing color of the ocean as we went from shallow to deep water and the increasing intensity of the waves – though that much movement did give me a killer headache.

By the way, I’ve included a picture of me as I was relaxing on the boat!

Anyway, someone told me that they saw a flying fish while we were on the boat. Though I didn’t get to see it, I wondered if it may have been herbivorous. I determined that it was unlikely they were herbivorous because none of my research on herbivorous fish had mentioned flying fish.

Finally, the boat landed, and we got to see the island for the first time (it’s beautiful). We all settled down, had dinner, and had a group meeting to discuss what we’re going to be doing tomorrow. We also saw lots of crabs as we walked between buildings. The hermit crabs didn’t mind us at all, but the larger crabs quickly scurried away whenever we approached.

Overall, today has been very tiring, but I’m glad we’ve finally made it. I’m excited to see what’s in store!

PRE-TRIP EXCITEMENT

Leave a comment

Hi, everyone! I’m Michiel, and this blog will record my experience in Belize as I study mammals and herbivorous fish with the rest of my class!

In only a couple of hours, I’ll be on my way to ABL, fighting sleep, to meet with the rest of my class before we start our journey to Belize. I’m excited to get to explore the country, swim through the reef, and I expect that the physical exertion required of this class will be gratifying, but I most look forward to getting exposed to field research. It’s something I know very little about, and I had not imagined I would ever do anything outside of a lab before this class. I hope that this pushes me to continue to push my boundaries and explore topics in science that aren’t necessarily related to my field of study. I also expect that, through the exploration of different ecosystems and study of different taxa within the country, this class will create a deeper love and gratitude for biology within me.

I’ve been preparing for this class for months – buying equipment and getting my passport – but I began to start preparing mentally about a week ago. I got really nervous about going to a new country and staying out in the wild instead of the city, and I still am a bit nervous, but I’m confident that the leadership from my professors and companionship of my peers will help put me at ease. Other than that, I just flew into Houston from El Paso in order to meet with the rest of my class, and I have been packing all day, racking my brain about the smallest things I may forget. I’ve been thinking a lot about the unbearable heat and humidity we’re going to endure. Coming from a desert, the Houston humidity is often too much to handle, and the closest I’ve ever been to the tropics is Cancún, Mexico, which was filled with many more opportunities for relaxation than I expect we will encounter in Belize. However, I’m hopeful that I will quickly get used to it so that I may put my focus to the work we will conduct.

Though I have bits of anxiety about the trip here and there, I am very excited for our trip and hope to return a changed person.
