Day 3: Penicillus Project + Coral Graveyard

Today we started to think more like field biologists by using tools such as our quadrates and transect tapes to measure densities and volumes of objects such as coral heads! We came up with a scientific question and hypothesis to test about the green algae, penicillus. We wanted to test how the penicillus density would change as we got into deeper waters. Our class could perform this data collection if we all went vertical by shoring using our transect to measure our 100 ft from shore, and then using our quadrat to search for and identify penicillus among the sea grass. Our hypothesis was that penicillus would be more abundant in shallower waters, due to higher sunlight and more nutrients, but we were wrong. Our data supported the idea that penicillus was more abundent in deeper waters and was typically seen not solitary but in groups. We presented our evidence and conclusions to our professors and they seemed impressed for our first field biology project. Maybe some day in the future we’ll try to experimentally determine the reason for this (possibly competition with sea grass or other factors).

Here’s us working and discussing our presentation of our data

While we were working on our presentations Nyala and Caio brought us coconut meat which was a delicious snack!

Later we visited our Professor Correa’s favorite place on earth- the Coral Graveyard. The coral graveyard has all different specimens of corals that seem to be very well preserved.  There was stag horn coral, different species of brain corals with cool patterns and ridges, and there was also a type of coral that is so rare that there has hardly been any sightings in the last 40 years (before the coral disease epidemic). It was very important that we know learn to match these corals up with live species that we may encounter in the reef! We also discovered a fossilized palm tree species which Dr. Solomon is pictured holding!

I spotted a coral specimen that had  a possible annelid boring mark. This was probably a type of worm hole! It was perfectly preserved and I wonder what type of annelid could have made that mark.

There was also some specimens of Bladed Fire Coral (millepora complanata) which is a common hydrozoan reef-building coral in Glover’s reef! Bladed fire coral has very small hair-like polyp holes compared to most other species I have encountered.

I can’t wait to see more of Glover’s tomorrow and hopefully go on a boat snorkel trip!

Day 14: Thank you Glover’s

As a thank you to Glover’s for hosting us, our last and final project looked into the composition of marine debris on middle caye of Glover’s Reef Atoll. I collected trash from the dock, and as I was collecting, I definitely felt like I was overheating. I am glad that most of the day we spent under the shade, where I got to cool down and “rest”. As the day went on, I felt much better, and got to enjoy the last glimpse of Belize until I don’t know when.

After lunch, I got to dissect a lionfish and we looked into the stomachs to see if fish were present. Unfortunately all the lionfish had nothing except of Liz’s group. I gave the last taxa presentation on Annelids, and after Herbe gave us a warm presentation on the history of Belize. After, we had our lionfish snack and OH MY GOD it was so good, like I could eat these invasive species everyday with some tortilla chips.

Aunt Annette and Jamelle, I will miss your cooking. I have enjoyed all the meals I have had here at Glover’s and if I had to choose a favorite meal, I do not think I could. Just the sheer power that the two of you have, making buns for our hotdogs and hamburgers, to meeting all of our needs, words cannot express my gratitude. You guys are one of the reasons that made all the bug bites worth it.

After dinner, we all met up at the dock to just wind down before our early morning back home. I am not looking forward to the three-hour boat ride. Anyways, we all just looked at stars, saw a couple of rays, and just enjoyed each other’s company. Also, I have been ruled the “quietest” of the 11 TFB’s so I guess that makes me cool? I wouldn’t say I’m like quiet, but compared to the group, I do agree with the status. I will miss all of the funny stories that the class has shared, but more importantly, I will miss all the days where we had slap each other on the back/head to kill sand flies. That is true friendship. Thank you Glover’s.

Day 2: Wipeout

It is the second day of our journey and today we got to swim at Rio on the pools before making our way to Caracol.  We had a nice breakfast on our last hour at the resort, and that was our last glimpse of the world. Sad but exciting time. At Rio, we swam for about an hour and I did slip and fall. It was like the TV show wipeout where the contestants slip and you laugh, well you would’ve laughed at me as I fell. Goodtime.

As soon as we passed a Mayan bridge on our way to Caracol and into the Chiquibul region, epiphytes were everywhere. From long vines to large fan like plants on the sides of trees (bromeliads and large lianas), they covered the forest. At Caracol, many epiphytes were present as well. Figs were present, bromeliads were present, as well as orchids. The black orchid was spotted near a bridge by the front, in which that is the country’s national flower. Many great sightings but above all, the history was very fascinating.

At Carcaol, we were given a tour of the site by our driver, who was extremely knowledgeable about the history of the Mayan ruins at Caracol. We climbed many buildings, one in which was for the king (people of high class). This building is the second tallest building in Belize, right behind a skyscraper in Belize City. We got to see a burial site in one of the ruins, and the system in which they bury people is very fascinating. Also, did not see bats in the burial site, in which the tour guide had warned us about, but it didn’t stop me from wanting to go inside.

At Las Cuevas Research Station, the scenery in second to none. It started raining as soon as we got here, but even that made the scenery better. Standing on the balcony and just taking everything in was a great introduction to Las Cuevas. Listening to the birds singing, to crickets chirping, Las Cuevas is the perfect place to start our journey tomorrow. Well that is it for today’s blog. See you tomorrow as our adventure is only getting started.

Back to reality

Even on our way to the airport we managed to squeeze in one last snorkel. This time we went to the mangroves and swam around their roots, which many organisms use as a substrate to grow on. Fish also use mangroves as a nursery where they are fairly sheltered from larger predators. Upside-down jellies bobbed along the bottom of the sea bed and fire sponge glowed orange through the murky water.

I finally saw the magnificent feather duster, recognizable by its larger size and double crown of radioles. Their tubes were attached to the mangrove roots, among the encrusting algae, sponges and hydroids. They were various shades of brown and white and tucked their filter-feeding radioles into their tubes if you touched them. Unlike the other feather dusters I’ve seen, they didn’t tuck their radioles in all the way, and the tips of the crown poked out of the tube. I am guessing this is because they are too big to fit all the way in.

Time has never passed so quickly as it did on this trip. We were so busy and there was so much to do and see that the two weeks were over before I knew it. I was never bored for a second. Being back in Houston is so strange and claustrophobic. I already miss the fresh air and pristine nature. I’d take that over clean laundry any day!

Glovers Atoll

Today we left land and moved out to sea. I enjoyed our long boat ride out to Glover’s Atoll, its been a while since I’ve been on the ocean and the waves felt great. It’s a beautiful place out here. After orientation we hopped in the water for a quick snorkel on the patch reef. I ended up having a few technical difficulties towards the end that hopefully practice will resolve.

I am already having more luck with this taxonomic group. I saw two orange Pomatostegus stellatus (star horseshoe worms) growing on a coral, and apparently Grace found Spirobranchus giganteus (christmas tree worms) as well. Besides annelids I saw staghorn coral, a queen conch, a ray, and a ton of fish, soft coral and sponges I couldn’t specifically identify.
