D-4 Impaling my taxa :’(

Leave a comment

Today the day started pretty wonderful, we got to bring many organisms from the local coast to the wet lab and have the many experts in our class identify them and tell us a little about each species. From this activity I really liked looking at things under the microscope, specially I got to look at a cool coral fragment that someone found! I also got to see a mantis shrimp for the first time!

Later in the day, we came up with a new question and went out to test it on different corals than those we had explored earlier in the week. With our research we want to understand if there is some sort of correlation between the amount of sea urchins observed and the amount of live coral. Our question originates from how sea urchins burrow into the corals which may weaken the coral and leave them more susceptible to disease. During our time on the reef patch we collected enough data, yet collecting that data was sure an adventure. The waves were way stronger than we had anticipated and we were constantly pushed into corals or our partners before we got to get the information we needed. Yet thankfully we were able to get data and also collect some urchins which we later examined back in the lab. (Don’t worry, we are taking good care of the sea urchins and will return them home tomorrow!)

We then went to a second patch this time not to work but to do some relaxing snorkeling. It was during this second snorkeling that I was shocked to see a lionfish flopping mid air on a stick. I was sad to see a member of my taxa of interest (piscivorous fish) that way, yet I also know that these can be really damaging to biodiversity, so I am glad that our team could contribute to improving the probability of many other species to survive via this kill of an invasive species. Also I am glad that some member of our group who really really want to try them will have a great dinner tomorrow(?)!

Also regarding tomorrow, I’m nervous but I also can’t wait to continue researching our question about corals and sea urchins to see what we discover!

D-3 Marine Quadrats and a Coral Gravesite?

Leave a comment

Hi everyone!

Today was pretty great, we got to do a bunch of new things as a group! For example today we worked with transects and quadrats under water for the first time. At first it was a little challenging, specially with two new devices and a clipboard to carry while swimming yet working as a team definitely helped. With a little bit of practice it got easier for me and my partner to place the quadrats correctly and then assess the amount of green algae in that patch. Although we were all able to gather data, our data ended up not proving our initial hypothesis. Originally we predicted that we would see a decrease in green algae as we moved further from shore, yet the opposite appears to be true. Although we do not know why, we infer that it could be due to over-competition from the sea grasses.

Later on in the day we went to what Dr. Correa called the coral graveyard. I thought it was so amazing how well preserved so many corals were after being fossilized. We had a small learning activity there in which we learned to pair some corals with their species name. Although many people got the names down quite quickly I can’t say I was one of them. Yet, I took photos of them and their respective names and plan to study them! I really enjoyed everything we did, yet I think working on our poster to present our data was my favorite part!

Regarding my taxa, I didn’t get to see any of them today. I am sure I will have a greater chance of seeing piscivorous fish whenever we go to greater depths!

D-2 The mangroves of death

Leave a comment

Hey everyone!

Today the day began fairly early for all of us, with breakfast at 7. The breakfast was so great, I specifically loved the banana pancakes! Then we suited up and got ready for our first dive. It was great to finally get into the water, specially because it was so refreshing and because we got to see so many amazing species. I got specially excited when I saw a Highhat (a piscivorous fish, my taxa) eat another smaller fish! Sadly I didn’t have the camera with me on the first swim so I didn’t get to take a photo (yet, even if I had the camera I am not sure I would have been fast enough!)

After swimming for a while we came back onto land and got lunch. As always the food was great, I got some french fries, cole slaw, and two raisin cookies. After lunch we went for another swim, yet this time it was a completely different experience: we went through the mangroves of death. There, we all got aggressively bitten by the blood thirsty mosquitoes. We all ran into the water hoping it would stop, yet they followed us in. Thankfully, as we moved further in they left us alone and we were at peace to take photos (and attempt to complete the scavenger hunt!) I personally did not finish the scavenger hunt yet I got to see so many cool fish, sponges, and many hard and soft corals. After a while we got asked if we wanted to run back through the mangroves of death or swim a much longer route. Without a second thought we all chose to swim back. After we got back many of us took the chance to shower. Then we watched two presentations about hard corals and soft corals. Afterwards we got a much needed break before dinner. Later at dinner we got really tasty rice and cheesecake! To conclude our day, after dinner we all listened to a few more presentations, this time about coral reef framework and growth, sponges, ctenophores, and jellyfish. Today was very fun and also a little tiring, yet I’m more than sure that we will all be ready tomorrow morning after a well deserved 10 hour nap.

D-1 Our Belizean adventure begins

Leave a comment

Hi everyone!

Today went pretty smoothly in terms of travel!

We all met pretty early at Rice and traveled to the IAH to board our flight which departed at 10:07am and arrived in Belize at 11:30am. We then got picked up by our tour guides who took us to a local supermarket where we all stocked up on a variety of things. I got bug spray, a local brand of chips and also a bag of cookies that seemed tasted really great! Then we were sent off by our guides on our next adventure: a boat ride that would take us to our final destination for the week: Glover’s reef. Yet before that we got some lunch from our guides which included tortillas, chicken, cheese and vegetables. During our boat ride, some of our team felt a bit sick due to the constant movement of the boat, particularly once we left the safety of the reef and were in open ocean. Thankfully once we reached land it appeared that the symptoms subsided for most people affected. Once we all reached the Glover’s reef, beyond a doubt we were all very exhausted. Yet even when exhausted we were all mesmerized by the beautiful sunset we got to see! Although I really liked the sunset (and even attempted to take a photo), my favorite part was dinner! The food was amazing! I remember during our first meeting we were told the food was great, at the time I remained skeptical, but that was not an overstatement. The mash potatoes and rice were so delectable! I also really appreciate how Hortence and Ashley cared about my vegetarian dietary restrictions, it was super nice of them! Before the night ended we all reconvened and met our three safety officers: Claudius, Adrian, and Ruth and also captain Eli.
Although today was tiring for all of us, it was also really exciting. I can’t wait to see what is in store for us tomorrow! Although I did not get to see any piscivorous fish today, I hope that tomorrow I get to encounter some of these!

D-0 Belize here we come!

Leave a comment

Hello everyone!

My name is Maggy, and I am a rising senior at Rice!

Coming into this trip I am so excited to get to learn even more about Belize’s biodiversity. I learned about this class my freshman year, yet due to Covid-19 I thought I wouldn’t be able to participate during my time at Rice, yet thankfully I was wrong! Going to a whole new country and getting to learn about its great biodiversity seems like a dream come true.

One of my goals of this trip is to become much more acquainted with both of my taxon groups: piscivorous fish and bees! Both of these groups have so many amazing organisms, I hope our group gets to see at least some of them up close.

I can imagine that this trip, in addition to being fun, will also be challenging at times, yet I’m looking forward to working with my classmates to overcome these challenges, just like researchers do out in the field! One personal challenge that I am a bit nervous about is swimming. I have never been a very fast swimmer, yet I hope that a few days in the water will help me improve my speed! Another personal challenge is working out in the field and putting to use my research skills. To me this is a challenge because most of my research has been lab-based, with me spending lots of time working with my laptop or at the bench. I believe that with just a bit of practice I’ll be able to quickly adjust! I think some of the classes I’ve taken at Rice will definitely help, for example I took a Conservation biology lab in which we worked with transects to estimate the biodiversity of the Harris Gully Natural Area at Rice. Another class I think can come in handy is a Plant Diversity course I took; since this course took place a few semesters ago I am not too sure how much I remember, yet I think seeing things first hand will help jog my memory. 

Regardless of the challenges all of us will probably encounter, as a group or as individuals, I am sure that this trip will be a success and that we will all learn a lot more about the great biodiversity of Belize!

Post-Belize Reflection

Leave a comment

Wow! What an amazing experience! Our class of 11 was constantly at work hiking, setting up pit fall traps, collecting data with transects, snorkeling, collecting data with quadrads, interpreting data, putting together poster presentations among other activities. In total, we accomplished 6 research projects with poster presentations for each of them. For each research project, we learned something new and interesting about the unique environment that we were living in for half a month. The experience involved a lot of hard work both physically and mentally, but it rewarded me with knowledge, fun, friends, and a lasting appreciation for the beauty of this world. It is nice to be home, where there’s air conditioning, WiFi, warm showers, less mosquitoes, no sandflies, but I will be thinking about Belize and my experience there for a long time to come. Thank you Dr. Solomon, Dr. Shore, Las Cuevas Research Station, and Glover’s Reef Research Station—for this one-of-a-kind opportunity!

Lepidoptera:

  • Eurytides marcellus, Zebra Swallowtail
  • Morpho peleides, Blue Morpho
  • Ascalapha odorata, Black Witch Moth
  • Sphingidae genus, Sphinx Moth
  • Heliconius hecale, Tiger Longwing
  • Eacles imperialis, Imperial Moth

  • Papilio polyxenes, Black Swallowtail

Piscivorous Fish

27/05/19 I’m not lion…I had fun.

Leave a comment

Today is our last full day of class since tomorrow is just traveling! We began the morning with a fun activity—cleaning up the island! We took trash bags out, geared up with long pants tucked in socks, shirts tucked in pants, jackets tucked in rubber gloves, and picked up garbage at four different sites around Middle Caye—the mangroves of death, the coral graveyard,  the Glover’s Reef dock, and the touch tank. I, along with Pierce and Keegan, picked up trash at the coral graveyard for 30 minutes. My hands pruned up with sweat, but the coverage was worth the mosquito protection.

 

Some interesting garbage found:

-lots of plastic bottles, lots of plastic bottle caps

-plastic utensils

-many sole-mate less sandals (ha!)

-Crocs

-baby doll leg

-stuffed animal

-LEGO

-toothbrushes

-rope

-2 hyperdermic needles

-a crab using a round bottle as a shell! Trash Crab!

Then, we had some coconut water, coconut meat, and lionfish ceviche—just doing our part to remove invasive species. The lionfish that I dissected was a 79.1g virgin male, and we found a whole, un-digested juvenile slippery dick wrasse in his stomach! The wrasse itself was at least 3 centimeters, maybe even 4. What a cool find!

We had our last lectures for the course on annelids and the history and culture of Belize given by our wonderful guides Herby and Javier—they were excellent and they will be missed so much!

Thank you Glover’s Reef Research Station for a fantastic week! Now, I’m prepared to head on home.

26/05/19 Urchin Searchin’

Leave a comment

We began the morning with a survey of sea urchins in patch reefs (in and out of marine-protected areas). We collected urchins in a bucket, then identified them by species and determined the diameters of their tests (in centimeters). We found long-spined urchins (Diadema antillarum) (don’t touch!), slate-pencil urchins (Eucidaris tribuloides), reef urchins (Echinometra viridis), and a few West Indian sea eggs (Tripneustes ventricosus). Although I was hesitant to jam my hand into small crevices in the coral to retrieve these spiny creatures, I had fun catching the urchins while simultaneously discovering how stubborn they can be. Some of those sea urchins were really wedged into their crevices and would not budge.

Bucket o’ urchins!

We collated our data into a poster, then transitioned into lectures on  crustaceans, hydrozoa, cubozoa, scyphozoa, ctenophores, and climate change and its effect on coral reefs.

We ended the night with a night snorkeling session from the dock to a patch reef nearby (which we got lost on the way to). It was a surreal experience. In the brief time that we were out in the water, I did not get to see much, but the creatures that I saw —including some tasty-looking lobsters—were vastly different from the ones that I normally see during the day. Our limited field of vision under water made for an invigorating experience, like when sting rays appeared and disappeared from darkness.

25/05/19 The Chummiest of Friends

Leave a comment

This morning we completed (you guessed it) more transects! Again, we went out to two patch reefs, one in an MPA, one not. The first patch reef (within an MPA, nicknamed ‘the Aquarium’) contained lots of fire coral hidden in the coral we were attempting to survey. Weaving the transect tape and manipulating the quadrad was especially hard with the stinging fire coral around, especially since the water was so shallow—there was a limited amount of space above the reef through which we could float. At one point, I was floating directly on top of fire coral—a precarious situation. At (what was intended to be) the second site, there were moon jellies floating around, so we decided not to complete our transects there and opted to move to a different non-MPA site for our final transects. The final area that we decided on to be our non-MPA site was full of lionfish (yum! that’s my taxon!) and squid! After completing my transects, I watched Herby spear a lionfish that was hiding deep within the coral. I am excited to eat these lionfish at a later time.

In the afternoon, the class took the boat out to the fore reef, where we saw the reef drop off, sponges, and bigger animals in general, however, many of us (myself included) fell ill and could not properly appreciate the majesty of the reef in our conditions.

Seasickness

We ended the night with lectures on Anthozoa (non-reef building zoanthids, corallimorphs, and anemones), marine mollusks, and threats to coral reefs (of which there are a lot).

24/05/19 Piscivorous fish are more metal than herbivorous fish. Periodt.

We took the boat out for the first time to survey two patch reefs. The first one, Marisol, was within a marine-protected area (MPA). The second was not within a marine-protected area (non-MPA). There were some grey clouds in the sky as we drove out to the first patch reef, but I did not feel the sprinkling as I was snorkeling in the cold water. I saw snappers as usual, and what I thought to be a foot-long grouper that quickly swam away before I could fully process its presence.

In the afternoon, the class geared up to wade into sea-grass off of the island. We were looking for creatures to capture and keep in a ‘touch tank’ briefly for our observation. As a class, we caught many queen conchs (and one conch shell occupied by a crab), two donkey-dung sea cucumbers, a sea egg urchin, a pencil slate urchin, a red heart urchin, an octopus!, two fire worms, a damselfish, several brittle stars, two sun anemones, several types of coral and algae, and many hermit crabs—no piscivorous fish though! The water is too shallow for these big boys. It was interesting to feel and observe the organisms from other taxons though. The donkey dung sea cucumber was particularly interesting as it molded into your hand as you squeezed it.

We ended the night with lectures on herbivorous fish, piscivorous fish (given by yours truly), and how competition, predation, and environment shape coral reefs.
