Camera Traps in Las Cuevas

5.26.2017

Today marked the first full day here at Las Cuevas and an interesting one at that. The day started bright and early with birdwatching. Although I heard many bird calls, I only saw vultures and a Plumbeous kite (a lot like a rainforest pigeon) which prompted my tired self to go back to sleep before breakfast.

After breakfast, we were given our task for the day: to go out and set camera traps in the area surrounding the research station. We planned for an hour or so and then set out to the 50 hectare path to set out six of our fourteen cameras before lunch.

On the way, I saw so many ants! I saw leaf cutter ants (A. cephalotes), army ants (E. burcellii), and ants that Scott and I have yet to identify. There were also Acacia ants (Pseudomyrmex spp.) on a small tree with Beltian bodies (nutrient-filled swellings on new leaves).

Besides ants, I also saw a blue morpho butterfly, a longhorn beetle, a millipede, a scorpion-eater snake, and a Mexican porcupine. I also saw some beautiful orchids.

We arrived back at the station late for lunch, ate, then headed right back out onto a different trail – the Monkey Trail – to set out the rest of our camera traps. We decided to set them out a kilometer apart, which kept us out there in the rainforest past sunset for a total of five hours during which I saw more leaf cutter ants (A. cephalotes), noticed scat (poop) and scratches likely from a jaguar, and came face to face with the most dangerous snake in the Chiquibul rainforest – the Fer de Lance .

While setting out our last camera, we got slightly lost trying to find our way back to the trail. Thankfully, we had a GPS and a machete to help us but it was still pretty intense; the staff at the station told us they were about to send rescue in after us. Walking back in the dark was neat, despite the fact that I tripped over a branch and pulled a ligament in my left foot after trying to jump over a fallen tree trunk blocking the way.

The long trek left not only my feet sore but also my stomach grumbling, so I had two full plates of food at dinner. It seems that I’m not the only exhausted one, because evening lectures were cancelled. Now I’m icing my foot which I hope will be better by tomorrow so that I don’t miss out on any other activities. Although today has been tiring and crazy, it definitely makes for a great story to tell once I get back home.

Off the Grid at Rio-On

5.25.2017

This morning was the last opportunity to have any sort of connection to the outside world before heading to the rainforest. Although I’m going to miss talking to my family and friends, it’ll be nice to disconnect for a few days.

On our way to Las Cuevas from Crystal Paradise, we stopped at the Rio-On Pools which were really incredible. I got to climb around on rock formations, stand underneath a small waterfall, and ride a “slide” into a pool of water. The scenery was beautiful and I loved photographing it all. Despite hurting my butt on a rock going down the slide, I had a great time. I even got to see what Scott called the “Golden Butt Ant” (C. siriceventris).

Once we made it to Las Cuevas, we settled in and had lunch before hitting the trails. Going along with the Maya theme of the Belizean forest, we climbed a Mayan pyramid structure and saw a ball court. During the hike, I saw the clear-cut foraging trails of leafcutter ants (A. cephalotes) and a pretty large nest of them, too. Scott stomped on the nest to provoke the soldier ants, and it was really cool to see them all pour out of the nest even though a few made their way into my boots. I also got to hold a green anole.

The day ended with lectures, which were really difficult to stay awake through even though I gave one myself. Definitely ready to go to sleep.

Team Flying Pizote Explores the ATM

5.24.2017

Today was the first full day away from Glover’s and it has been a bit of an adjustment. Adrienne said it best when she compared the transition to the terrestrial portion of this course to the first amphibians transitioning to life on land. I wasn’t ready for hot, muggy air untempered by the ocean breeze. Bugs were flying into me while walking and falling into my dessert at dinner. But besides the small impracticalities, today has been incredible.

After a brief hike during which I struggled to doggy paddle through a cold river and slipped on algae covered rocks, I finally got to the mouth of the first cave I would ever traverse: the Actun Tunichil Muknal (ATM) cave. The experience was etherial. The cold, clear, bluish-grey water of the cave shocked my senses and the crystals sparkling in the formations of the cave entranced me. I wish I could have taken a picture, but the images in my mind will have to do.

Besides just the structure of the cave itself, the contents it held were remarkable. The Mayan ceramics and especially the skeletal remains sent chills down my spine. It was a bit concerning, however, that the last and most complete skeleton was my height exactly.

I didn’t see too many ants today because of all the rain, but I did manage to see a male army ant (E. burchellii). I hope tomorrow I’ll have better luck with ant sightings and will have some interesting anecdotal information to include in my taxon briefing.

Note: The lack of photos in my blog post has been brought to you by the tourist who dropped his camera on an ancient Mayan skull.

On the Ground and Away from Glover’s

5.23.2017

Leaving Glover’s today was so sad that I asked if I could permanently live in the snorkel shed. I felt like I was finally getting to know everyone on the island, finding a rhythm and place there. I was even recognized by one of the staff as “the girl who scored the beautiful goal.” I’m truly going to miss the island lifestyle, especially a small island like Glover’s, and the way that everyone gets knows each other and becomes connected.

Speaking of small islands, after leaving Glover’s we visited another research station operated by the Smithsonian on a tiny speck of sand called Carrie Bow Cay. We got a tour of the facilities and a rundown of the research projects taking place on site, as well as interesting insight into the nature of toilets in the field.

After that stop, we headed on toward Twin Caye. The mangrove forest there was made up of entirely of red mangrove (R. mangle) from what I could tell.

We walked through the peat which was goopy and gross, then snorkeled around the edge of the mangroves.  The snorkel was much more enjoyable. I saw schools of small snapper, a starfish, a juvenile sting ray, sponges, and even a seahorse.

Once we finally made it to Belize City, we had lunch and drove down to the Tropical Education Center (TEC) for the night. We walked some paths on the grounds before dinner and saw some Acacia ants (Pseudomyrmex sp.). After about an hour, we went to dinner then to the Belize Zoo which was such a cool experience, especially because the nocturnal animals were active. My favorite was seeing the big cats: the puma, ocelot, and jaguar. Tony the Tiger’s frosted cereal has nothing on Junior the Jaguar’s somersaults. I even got to hold a boa constrictor!

All that excitement still hasn’t convinced me to switch from team marine to team terrestrial, though. Fair to say that a frog falling from the ceiling and almost landing in my hair, as well as having to share shower time with a moth, a beetle, and a lizard keeps me skeptical. Let’s see if the caves tomorrow have me singing a different tune.

Warm (Make that *Hot) Welcome from My Taxonomic Group

5.16.2017

Today started bright and early at 4:00 am to catch a flight from Miami to Houston without much of a break since. Needless to say, the lack of sleep and full day of traveling has left me completely exhausted. That’s why I am excited to report that I get to sleep in until 5:30 am tomorrow when breakfast starts! Note the hint of sarcasm?

All jokes aside, today has been really incredible. I am usually a proponent of aisle seating on planes, but I decided to take the window seat and I’m glad I did. I got a beautiful bird’s eye view of Belize and all the tree canopies that blanket its terrain.

After landing, we swiftly made it through customs and our driver met us outside to take us to the Tropical Education Center (TEC) where we are staying for the night. On the way, we stopped at a small store where I bought some snacks (I’m super excited that they had mariquitas, aka plantain chips) and much needed shampoo and conditioner. I do not need to come out of this trip sporting dreadlocks.

Spotting and identifying species of my taxonomic group has been quite challenging today as you can see from the picture below.

It was really neat that within minutes, I was able to come across members of a key species of my taxonomic group, leaf cutter ants (A. cephalotes),  doing what they do best –  foraging for leaves to take to the fungi in their nest. It was also nice that the type of ant was pointed out and identified for me. Can that be the case at Las Cuevas too, please?

Another key find while walking to dinner was a juvenile green iguana up in the branches of a tree alongside the gravel pathway. I hope that all these sightings in such a short amount of time are an indication of the diversity I will get to see in the rainforest part of the course.

For now, I am extremely excited to be making the boat ride to Glover’s Reef tomorrow. Time to rest up for an early wake up call and another busy (but hopefully incredible) day in Belize!

 

T-1 Day From Crossing Belize Off My Travel Bucket List

This morning, I went out fishing on my boat in Miami and it suddenly hit me that the next boat I’ll be on will be headed for Glover’s Reef Research Station. It’s crazy how fast these past two weeks have gone but I am so excited to finally visit Belize. It was on my list of the top two destinations for my high school graduation trip, but I ultimately visited Costa Rica. Now I’ll finally get to go.

These past couple of weeks have been a whirlwind of catching up with family and friends, and ultimately procrastinating on my assignments for this course. As deadlines approached, I mustered the motivation to read the textbook, make sense of jargon in about 10 different research papers on mangroves, cringe my way through magnified photographs of ants, and put together three presentations.

Speaking of my presentations, I am kind of nervous to give them. My public speaking skills aren’t too great but I’m hoping that all the preparation I’ve done will carry me through my awkwardness.

Ultimately, the presentations are just a fraction of the course and I absolutely cannot wait to get out into the field. I hope I get to learn more about two ecosystems that have fascinated me: coral reefs and rainforests. Living in South Florida and being just a stone’s throw from the Bahamas has given me the opportunity to snorkel and scuba dive, awestruck at the beauty of reefs. And just the previous summer, as I briefly mentioned, I got to visit the Osa Peninsula in Costa Rica which gave me my first immersive experience in a rainforest.

With this trip, I am hoping to see these two ecosystems through the lens of a researcher and gain some practical knowledge about them that I can carry with me when I go diving or on future vacations. I’m also interested to compare what I see in Belize to the reefs of home and the wet season in Costa Rica. If I’m going to be ready, I should probably go finish packing.

No way… next time I post I’ll be in Belize!

P.S. I’m also hoping to take some great pictures like the ones I got from Costa Rica for memories 🙂

 

(Nakian) May 23: Tapir x Ocelot x Bye LCRS

Today is the last activity day at Las Cuevas Research Station. We finally retrieved the camera traps we set on the first day. I was not expecting much because I have heard how cautious wildlife are especially near human presence. But what are the odds, the cameras caught a curassow, a tapir, an ocelot, and a weasel looking animal that was hard to identify. The last camera trap was a blast with a big cat species we all hoped to see. The ocelot’s beautiful pattern was indeed mesmerizing.
The past several days at the LCRS I must say was extraordinary. The morning choir of the distant and closely birds, nocturne of the night insects, occasional cries of the howler monkeys, bustling processions of Leaf-cutter and army ants’ parade, and shimmer of the neighboring planet beside the tropical moon. Having the first-hand experience of the field biology on the crisp bed of fallen tree litters, rejoicing with the unexpected encounter with amazing species, I have never been so one with the nature before.
I still am not sure what my passion in the ecological field will be in detail. But I learned in LCRS that studying to approach ecological conservation of this biodiversity haven in the light of social, political, cultural, and economic perspective that I aspire to take could be a valid path, even one that could be healthy for me. I do not regret my decision to spend my time here.

Ant Day

Today we focused on some of the many ant species that habitate the Chiquibul forest. The cecropia tree has a symbiosis with azteca ants, which protect the tree from predators in exchange for shelter and food. We spent the morning testing a few hypothesis about how the cecropia trees avoid herbivores before they are colonized by the protector ants. 

This afternoon we excavated three leaf cutter ant colonies of different maturities. Once a queen colonizes a nest after a nuptial flight she can live for 20 years reproducing, expanding the colony until there are millions of ants at any given time. There are tunnels underground leading to chambers full of the ant’s fungus garden and pupae. The youngest ones are fairly small, but once they are 10 years old they get huge, with tunnels the width of your arm full of soldier ants ready to come out and attack you when you disturb them. They have quite a pinch and we were all thankful for our rubber boots today.

We had an unexpected amphibian sighting once we got back to our housing; one of the bedrooms had a large frog on a bedpost. I caught it and took it outside to get a closer look and try to identify it. It hiccuped in my hand, puffing out its chest, in protest to its capture. The frog was dark green and brown, with some stripy markings around the forelegs. I couldn’t examine its back without it jumping from my hands so I didn’t get a clear look. It was about 2.5 inches long with horizontal pupils, bronze irises and toe pads. The toe pads indicate that its a treefrog and since there aren’t many in the area I would have to guess that it was another common Mexican treefrog, based on size and color. I released it into the trees after a minute or two to not cause it too much distressed and it leapt from my hands with a defiant squeak.

(Nakian) May 22: Ants x Statistics x The Unexpected

Another big day for ants. We retrieved the pitfall traps we have deployed yesterday and the amount of ant species diversity was stunning. I identified species I almost lost hope of finding in this trip. I found Anochetus with long mandibles on narrow head, Wasmannia small but nasty, Neoponera with fat petiole, Pheidole big head and club like antennae, Carebara with giant head, and Adelomyrmex. Not having seen these species in day light, these findings really support my hypothesis that many of these ants are nocturnal, or at least not around in afternoon. However, I still could not identify half of species today, because many of them looked so similar, or were not in my taxa ID sheet. It could be that many of them were same species but in different castes, but I just could not distinguish them and considered them as same species. Also I have to consider that I tend to focus on exotic looking species when making my taxa ID sheet. Tonight’s night hike might give me some more opportunities to find more species. However many of these species are really small that I don’t know if I would be able to identify them so readily during the hike.
Today we had a long discussion about the result of our pitfall trap experiment. Different data interpretations flipped the results that made me think of how to approach data when making conclusion relevant and accurate for the question we are asking. I think I must train myself more in the ability to design statistically sound experiment and analysis methods. In a discipline with large data analysis such ability seems crucial.

Having spent a week in the field, it comes to me that unexpectedness makes field biology awesome. In a lab we can simulate the natural environment but the results are restricted from the limited perimeter. If I conduct an experiment here, I don’t know what will be in my trap. It could be nothing or could be bombardments of ant species I hoped to see. This unexpectedness turns field biology so attractive.

All About Ants

Today was all about ants! The day started with the developing and testing of hypotheses regarding the Cecropia tree and the Azteca ants. Azteca ants live in Cecropia trees, providing protection for the tree against herbivory. However, young Cecropia trees do not yet have these ant symbionts, so we looked at how these juveniles might avoid herbivory without their ant defenders. In the afternoon, we learned about leafcutter ants by digging up three ant nests at different stages. The first was about a year old colony, the second about 5 years, and the third at least 10 years of age. Learning about these ant societies was really interesting, as they effectively function as one super-organism.

Evidence of two species of mammals was definitely observed today. On our way back from the final leafcutter ant nest, we heard Mexican black howler monkeys from afar. However, the howling got significantly louder over the next half hour. We guess that the primates were likely about 100 meters from us at their closest proximity. I loved standing in the forest when some others had moved ahead, just listening to the roars of the howlers. We also saw a wrinkle-faced bat after dinner that had been caught in a mist net by another group at the station. The bat was much smaller than would be expected, and had a pug-like face. Some other animal sightings included army ants and a tree frog (on my clothing that was hanging to dry!).

I also gave my first presentation today on cave life. I’m very excited to put this knowledge to practice tomorrow in the caves! Hopefully we will see many more bats and other specialized cave species.
