Day 5: Our First Poster Day

Well May 19thwas a day for the books! We were tasked with our first project that we were to start and finish in one day. We were attempting to look at new pioneer plant biodiversity in hurricane gaps with tree regrowth vs not.  However, the hurricane gaps (tree fall areas induced by hurricanes) were so dense that we couldn’t enter the forest with the methodology we had created. So, we just ended up looking at plant biodiversity in hurricane gaps vs. forest.

We collected leaf samples from 10 different plots and then sorted them into morphospecies (categories of leaves that we think looked like the same species, not rooted in actual knowledge). It appeared to us that there was no significant difference between the two—had 30 morphospecies in gaps vs 28 in forest. We made a very lovely poster, and Scott thoroughly enjoyed our presentation.

After that, I gave my presentation on Amphibians! Everyone really liked my Frog and Toad slide especially. We had hoped it would rain so that there would be frogs out during our night hike, but unfortunately, it did not. We could hear frogs but unfortuantely couldn’t see them. I don’t think my eagle eye spotting was the best, and I was still somewhat confused by the calls of amphibians vs. insects, so the sound was hard to follow.

However, we did see lots of nocturnal reptiles including mud turtles, a red backed coffee snake, and a banded gecko! I also really enjoyed listening to the insect chorus of communication throughout the night. And I even had a chance to feel like Newt Scamander when I held a stick bug that looked a lot like a Bowtruckle! 🙂

Day 4: Pee in Vials, Not in Caves!

Written on May 19that 7:13 am

 

DISCLAIMER: Las Cuevas was supposed to have internet—right now, it isn’t working. All LCRS posts from the rainforest will be posted after the fact!

I didn’t write this blog post last night because I was just so, so tired! I fell asleep with the lights on (3rdnight in a row) with lots of people chattering around me.

Anyways, we started the day with birding—we tracked the beautiful scarlet macaw mated pair as they chattered away. During this time, Scott handed us 2 50 mL vials and told us to fill each with 25 mL of urine. It was a very odd way to start the day, but turns out, our second project had to do with nitrogen scarcity and insect diversity in the canopy vs the forest floor.

Once we developed our question, hypotheses, null hypotheses, and methods, we set out to bury and hang out samples along with water vial controls. We picked two different sections of the same trail and placed them roughly 100 ft apart. We’ll collect them after two days to analyze what kinds of bugs fell into our pitfall traps! During our hike, Sam did spot a red-banded coral snake under a log and we got to watch it slither away.

In the afternoon, we had the special opportunity to spelunk into the Las Cuevas Cave, just a mere 100 yards away from our clearing. It was beautiful!! The stalactites and stalagmites glistened, glittered, and shined with all kinds of minerals. Since the cave has technically been closed for archaeological excavation research, it was relatively untouched and purely natural. Biologically speaking, we saw a bunch (literally) of baby bats (see pic), adult bats, crabs, isopods, mites, and an amblypygid (a glorified spider), and a peccary skeleton. Mayan wise, there was a nearly intact bowl, a metate (grinding stone), faces carved into the rock (rudimentary, but very noticeable), bone fragments from human sacrifices, and lots of shattered pieces of pottery. It was really incredible to walk the same walk and see the same sights as the kings or high priests of the Maya culture did when they worshipped in this cave to their rain god Chaac.

In the evening, we had our lectures, and a somewhat rare amphibian sighting! There was a frog in the window, and I caught/held it (see pic). I’m unsure of what kind of frog this was, but when we reach internet, I’ll for sure look it up! (UPDATE: It was a Mexican Tree Frog without its coloring since it was night time)

(Hey Mom and Dad, do I look happy? :D)

Day 3: Surrounded by Green

Written on May 17that 9:31 pm

 

DISCLAIMER: Las Cuevas was supposed to have internet—right now, it isn’t working. All LCRS posts from the rainforest will be posted after the fact!

On our first full day at LCRS, we started our first project! We were given a method (camera trapping) and were tasked with creating a question, testable hypothesis, and a full methodology. After much discussion, tweaking, and organizing, we decided to ask about human impact on mammal traffic. We measured this by setting camera traps in pairs—one on the trail facing the trail, the other off trail facing away from the trail. We hope to catch some great cat (like jaguar) shots!

With all the details figured out, we left for to set up the first three pairs. We went from the station, down Monkey Tail Trail, and turned onto Saffron Trail. This broad daylight hiking was different than yesterday—the sun rays glowed through the trees lighting up the forest canopy with all shades of green. Most notable canopy spotting today was a large termite nest in the Y of some branches; it had to be at least 5 ft in diameter!

I sadly did not spot any amphibians today—I think this is because it is the end of the dry season, and not that many rains have come yet. Also, most of the Belizean frogs are nocturnal and we’ve just been hiking in daylight or dusk thus far. The tree frog from yesterday was really a treat!

Somewhat related to amphibians are boa constrictors! We actually had the incredible opportunity to spot one in the wild while hiking off trail to set the camera trap. The boa was directly in front of a 30 ft wide leaf cutter ant pile, so we were all having a field day with this nature sightings. The snake, on the other hand, was very nervous but never lunged—it just followed any moving person with its eyes.

When we returned from our hike, we had a chance to shower then hear from the Director of Friends of Conservation and Development Raphael. He explained to us that (in a nutshell) his NGO is responsible for patrolling the border with Guatemala and other high-risk areas to protect the wildlife. All in all, today I learned to appreciate the rainforest, and even more, the colors and battles of the rainforest of today really made me appreciate being in the rainforest.

 

Day 2: Three Days Packed into One!

Day 2: 3 days packed into 1!

Written at 9:43 pm on May 16th

 

DISCLAIMER: Las Cuevas was supposed to have internet—right now, it isn’t working. All LCRS posts from the rainforest are posted after the fact!

Today felt like 3 days packed into 1… We started at the Rio on Pools excursion, which is halfway to Caracol from our ecolodge. There, we swam, “showered,” and identified wildlife. I spotted several little puddles of tadpoles! Also, Claire helped me pick up one of the bigger ones for a picture.

When we left Rio on Pools, I fell asleep in the van, so waking up felt like a whole new day. We arrived at Caracol to observe the Mayan ruins and learn more about the culture. We also talked about forest reclamation over these structures, and we discussed the pros and cons of excavation. No amphibians were spotted on this trip, but it was great to see the birds, howler monkeys, lizards, and countless plants along the way.

Again, I fell asleep during the ride to Las Cuevas Research Station and woke up to an oscillated turkey in the road. Once settled in, we readied ourselves for our calibration hike, figuring out all our gear, hiking ability, and sharpening our eagle eyes. Kirsten spotted a Mexican Tree Frog (identified thanks to my Taxon ID card!) that was blowing up his air sacs doing a mating call, resting in the center of a palm frond. Scott lowered the leaf appendage so we could see it better and the frog promptly projectile urinated behind him and jumped forward onto Scott. He said the frog was slippery, so he couldn’t catch it.

We came back to a lovely dinner, and then we did our first night of lectures, it is now 10:18 pm and I am ready to go to sleep! 5 am birding calls my name tomorrow.

Day 1: All the Traveling

Written at 9:01 pm Belize time on May 15th

How excited am I to be in Belize? As excited as this dog was to take their picture!

This pup is the resident at the Crystal Paradise Lodge, our first place we call home on this lovely trip. It’s been a long day, but it was a great introduction to Belize. (We aren’t supposed to pet the dogs, but at least we can take cute pictures!)

We started at 10:30 am in Anderson Bio Labs on campus—we took a cute group pic for the Biosciences Facebook page/press release (not sure where to find that). Then we hopped on the bus and headed for the airport. Upon arrival, we found out that Claire’s dad would be our pilot! We ate Chick-fil-A and Pilot Jeff bought us all cookies.  Then we turned our phones to airplane mode (not before my last game of HQ for a while), boarded our plane, and left for Belize.

After going through customs, we met Edward, our van driver for the day. He took us to the local convenience store to get some snacks and whatnot—I bought shampoo and conditioner because, oops, mine spilled in my toiletry bag…  During our 2.5-hour ride, we talked to each other, looked through the savannah plains, identified recent burn areas, and learned about each other’s lives. It was a great time. I also really enjoyed talking to Edward and learning about Belize as a country. The highway we took was called the Western Highway, but it is now called the George Price Highway in honor of his role in helping achieve Belizean independence in 1981. We took turns looking out for our taxonomic groups, but I didn’t see any of mine (Amphibians or Sponges). Claire did see one frog in our bathroom, but I didn’t get a chance to look. From her description, it seems like an Hourglass Tree Frog, but who knows…

We arrived at the Crystal Paradise Ecolodge, where we were guided to our “cabanas” and then served a delicious dinner with really good cake for dessert. There are lots of cool bugs and animal sounds, and we are really into trying to identify them all. We are quickly learning that we haven’t even scraped the surface of the insects we don’t know… And now, I’m working on my blog and my field notebook journal.

This trip is off to a really high note! Scott and Adrienne have warned us that this first location is a ton nicer than the research stations and we should enjoy it while we can. Also, on a similar vein, blog posts will be posted only when internet is accessible. Las Cuevas has an ethernet cable, but my computer doesn’t have an ethernet port… So, we shall see what happens. No idea about Glover’s Reef yet.

I hope that we will have ok enough internet to post every day, but I apologize in advance if we won’t be able to!

Let’s Go to Belize!

As I sit in my childhood backyard in Atlanta, GA, I think about all the bugs that seem to be nipping and milling about. I can only help but wonder what the bugs and critters will be like in Belize… I imagine that the mosquitoes will be much worse!

I’ve traveled to Belize before, but that was on a live-aboard sailboat! So, I’ve never been to the rainforest, and I’m really looking forward to seeing the rich fauna–even if they are hard to find. I’ve been researching amphibians, and though there are lots of them, every site says they are nearly impossible to spot unless you have a watchful eye. I am a little concerned I won’t be able to spot them as well as others because I am so short, but maybe they’ll be more on the ground!

I am most looking forward to spending time on the reef. I love being in the ocean, swimming about, seeing the fish, corals, and everything in between… I’ve always had an interest in marine biology, and I had an internship 3 summers ago at the Georgia Aquarium with the animal husbandry specialists. I’m excited to see how my research on sponges (which I also looked at back in sophomore year of high school) compares to real reef life.

All in all, as soon as I can pack, I am ready to hop on that plane and get there! I am ecstatic I get to share this experience with other equally invested and dedicated Rice students plus Surf+Turf. 🙂

EBIO 319 2018 woot woot!

I can’t Belize it’s over!

One of the most striking similarities in between the Rainforest and the Coral reef, is the sheer number of microclimates that each organism has specialized into. Both the rainforest and the coral reef have such wide levels of biodiversity because each organism has adopted a tiny niche. Both environments also exist in a nutrient deficient state. The rainforest has low nutrient enrichment in its soils. The coral reef also exists in a low nutrient environment. Both exist in states of nutrient deficiency due to a high turnover rate and the sheer number of organisms that need those nutrients.

The rainforest and the coral reef seem to have very similar structures. I have observed that the canopy of the rainforest is similar to the hard coral structure of the reef. Both the canopy and the hard corals support large amounts of life. However, there is even more life teeming underneath in the crevices of the coral and in the understory of the rainforest. By setting pitfall traps and shifting the dead coral pieces while looking for urchins, I got to see a whole new side of both environments. I learned that there is a huge diversity of invertebrates on the forest floor and that for every organism I see on the surface of the coral reef there are ten more underneath.

One of the major differences that I have noticed in the rainforest and on the coral reef, is that the rainforest appears to be more stratified. The organisms in the rainforest that exist in the canopy are rarely found on the forest floor. On the other hand, the fish that are swimming above the coral reef at one moment can be found in a crevice the next. I believe that the water filled environment of the reef allows for greater movement of organisms between the different sections of the coral reef.

I expected that I would really enjoy EBIO 319, but would prefer the marine part of the course! However, I ended up loving the rainforest section equally as well as the marine. Furthermore, I didn’t really expect our class to click as well as it did. I think that by the end of the trip, we all had become good friends. On a side note, I expected that I would leave the rainforest as one giant mosquito bite. However, I didn’t get a single mosquito bite while in the Chiquibul. Similarly, I didn’t expect the rainforest to be so cold. I had to put on a sweatshirt most mornings in the rainforest.

My favorite part of the course was the ATM cave. It was one of the coolest things I have ever done! I also loved designing our own experiments and applying them in the field. I loved that we were given the freedom to see what worked and didn’t work in each study. My least favorite part of this course was of course leaving. I wish that I could stay in Belize forever. I also didn’t love the Christmas tree worm study, but that was primarily due to the very low density of worms!

While I know that I won’t remember won’t remember the details from the presentations or taxon briefings five years from now, I will remember some of the most important guidelines to being a TFB. Rule number one: When you are in the field, things will inevitably go wrong. You must always be prepared for a change in plans and to think of a way to fix a problem like using a vine to tie a camera trap to a tree. Rule Number 2: Always carry a headlamp, a snack, and water! You never know when you will be making it back to base camp and should always be prepared to spend the night in the woods. Rule number 3: always bring plastic bags! There were countless times on the trip that I found my self wishing for a plastic bag to hold wet clothes or to organize equipment. The most important thing I learned is that I love doing field work and want to pursue become a tropical field biologist in the future!

Leaving Belize* cries* (May 30th)

Today, I woke up at 5 am to watch the sunrise and listen to the birds. I didn’t see many birds, but it was nice to drinking coffee and watch the sun come up. It was a bittersweet moment in which I got to reflect on everything we had done on the trip and everything I had learned. I can’t believe that we are leaving Belize today. This trip has been quite the adventure and has passed by so quickly. Hopefully, I will get to come back someday!

We left Las Cuevas Research station around 8:20am and drove to the Golden Grove, a souvenir shop. Then we got back in the car and continued on our trek to the airport. Along the way, we stopped at a restaurant called Cheers for lunch. They had really good watermelon juice!

I did not see any amphibians today. The closest I got to an amphibian sighting was a painted frog on a plate in the souvenir shop. However, I saw more frogs and toads on this trip than I expected.

We made it to the airport shortly after! Sarah Glovers and I got selected for extra security clearing and got to get on the plane first! We saved seats for the whole group which was very stressful. We made it to Houston around 7:40 and passed quickly through customs. It was sad to say goodbye to everyone, but I know that I will see everyone around campus.

LAST FULL DAY IN BELIZE (May 29th)

Today, we are recollecting our camera traps. After breakfast, we set off on the 50-hectare plot. It took us way less time to collect all of the traps this time. While on the trail, I saw another Mexican tree frog. This Mexican tree frog was clinging to a small plant and had slightly different coloration from the others I have seen on this trip. This frog had slight green markings on its arms. After we got back, we completed all of our presentations for the trip.

After lunch, we hiked along the Monkey Tail trail in order to collect the remaining camera traps. It was really fun trying to find all of the cameras again deep in the forest. Unfortunately, the GPS wasn’t working perfectly, so frequently we had to use the sun and look for signs of our previous journey into the bush.

While in the forest, I saw an Dendropsophus ebraccatus (The hourglass tree frog) for the first time! This frog was much smaller than I realized. He had very unique coloration pattern. He had dark brown lines that contrasted with his bright white color. He was sitting on a small leafy plant.

After dinner, we looked at our camera traps! We saw peccaries, pacas, great curassow bird, and a brocket deer. The biggest catch of the night was 2 ocelots!!!! I really didn’t think that we would see anything on our traps! Today was a great last day!

The pitfalls of EBIO 319 (May 28th)

This morning after breakfast, we picked up our pit falls from the forest. There were a surprising number of ants and beetles in our traps. We sorted all of the organisms from each site into different morpho-species and measured overall diversity in the forest canopy and on the forest floor. We concluded that there was a greater nutrient abundance on the canopy and forest floor.

After lunch, we went into the cave just outside of the research station. This cave was used by the Mayans for religious ceremonies. We could see some of the old platforms and stairs built by the Mayans. While in the cave, we saw a giant green snake scaling the wall of the cave. I got to give my last topic lecture in a secondary chamber of the cave. I think it is safe to say that that will be the coolest place I ever give a talk!

OLYMPUS DIGITAL CAMERA

After dinner, we hiked out to the bird tower to watch the sunset. The view from the tower was amazing! As far as you could see, there were rolling hills with no visible human presence. On the way back from the tower, we got to do a night hike. The forest totally changes at night. It was really incredible when we turned off our head lamps and just listened to the forest. We saw cockroaches with a glue like substance on their back and phosphorescent scorpions hiding in a log. We also got to see a tailless whip scorpion which is actually not a scorpion, but is in the arthropod family.

OLYMPUS DIGITAL CAMERA

Immediately once we got back, I found another Smilisca baudinii (Mexican treefrog). This frog was a much darker color than the other frogs I had previously identified of this group. This frog also did not have the yellow running down its side. This difference in color may be due to the frog’s ability to change its coloration between the night and the day. The other frogs were found closer to dusk than at pitch dark.
