20/05/19 Goodbye Las Cuevas!

Today is sadly our last day in the rainforest, but I am excited for the reef!

This morning the class again made the strenuous 8-mile journey down the trail along the right side of the 50-hectare plot, then the Monkey Tail Trail. We retrieved the 7 camera traps that we had set up along that path on our first day in the rainforest.  The class completed the whole trek before lunch while on the first day we took the whole morning (then lunch) and part of the afternoon. We definitely hiked at a faster pace, which made the journey a little harder. Along the Monkey Tail Trail, the class hiked faster in part because we did not want to give the ticks (hidden in the tall brush) the time to fall onto us and suck our blood.

I observed 3 blue morphos, but felt less compelled to catch them since my task had already been completed. I am at peace now. Out of the 3 blue morphos, 2 were spotted together and 1 alone. It seems strange to me that we have observed the blue morphos in pairs (At least 3 times over the course of our time in the rainforest) as they are supposedly solitary creatures. Either way, I appreciate every opportunity I get to see these iconic rainforest beauties.

That afternoon, the class went out to observe leafcutter ant/fungus obligate mutualism firsthand. First, Scott tried to excavate a younger nest in the clearing and find the fungus chamber, but was unsuccessful. Then, we found a HUMONGOUS ant colony along the Monkey Tail Trail—so large that it was almost the equivalent of a small hill that the entire class could stand upon. Scott managed to find the fungus chamber fairly quickly and grabbed a portion of the fungus for us to examine up close. Soldier ants came pouring out (as to be expected), and they were huge and aggressive. Amanda was bitten by one of these soldier ants and, in the process, it tore a small chunk out of her pants. Scott said that, given enough time, these ants could chew through our rubber boots. I am not going to test this claim out.

The class ended the night with lectures on the geographical and biogeographic history of Central American and the Caribbean and mammals. After the lectures came the exciting part—looking through camera trap pictures. In total, we captured 2 curssows, 2 unknown birds, 1 possum, 1 skunk, 1 tapir!, and 1 unknown earred animal. The camera that I adopted (its name is Rice 2) caught  a picture of a male curssow and a stunning picture of a tapir (I am so proud!). The picture is so clear that you can see the enormous size of its whole body as it walks along the trail. Probably the best photo of the lot! Another interesting capture was a photo of an unknown earred animal. The animal had gotten too close to the camera, and the flash saturated the facial features of the animal, but we were able to distinguish the shape of the ears and some fur, leading us to believe that the animal was a puma. It is frustrating that we cannot confirm this. Either way, a great and successful ending to an exciting week full of new experiences. Thank you Las Cuevas Research Station!

19/05/19 I finally caught a blue Morpho.

6:00am breakfast as usual. In the morning, the class hiked up the Maya Trail to examine an area disturbed by a hurricane a few years ago. The damage was apparent in the tree fall, but also in the difference in species composition between the disturbed and undisturbed areas of the rainforest—most notably, cecropia trees inhabited the disturbed areas abundantly, but not the undisturbed areas. The class surveyed plant species in both disturbed and undisturbed areas of the rainforest along the Maya Trail.

On an exciting note, I finally caught a blue Morpho! The butterfly made the mistake of settling on a leaf too close to me and not darting away while it had the chance, thinking that its leaf-like underside camouflage would save it. This bad boy was rather large at a wingspan of around 13 cm (blue morphos can reach a wingspan of 20cm). These iconic rainforest species have an easily recognizable iridescent blue topside, but with wings closed (as butterflies have the tendency to perch), the brown underside with eyespots blends into the butterfly’s surroundings. Blue morphos are also incredibly adept flyers, making them difficult to catch both in flight and not.

That afternoon, the class returned to the hurricane-disturbed area along the Maya Trail to examine firsthand the ant-plant mutualism between cecropia trees and the Azteca Ants that inhabit and defend them.

That night, the class hiked up the PAINfully steep bird tower trail to the bird tower. Although the hike was hard and the sky was cloudy, the stunningly beautiful view from the bird tower was unparalleled. The class spent over an hour at the bird tower until the sun began to set. I sat with my feet dangling off of the edge of the bird tower and enjoyed the breeze. We returned to the research station in the dark, and the downhill hike back was much easier. We saw a cave, and nearly stepped on a jumping pit viper, and at one point we all turned off our headlamps and (surrounded by darkness) just listened to the rainforest sounds.

The class ended the day with lectures on fungus, reptiles, beetles, and a lecture from yours truly on tropical parasites, diseases, and medicinal plants.

18/05/19 Introducing Sunshine the Moth

I rolled out of bed for 5:00am birding + a cup of coffee. Disclaimer: I am not a coffee-drinker, but early mornings have made it a necessity. The low, breath-like calls of the howler monkey were eerie in the pre-dawn darkness.

After breakfast, we hiked along the Maya Trail to pick up the pit fall traps that had been set up yesterday and left out for 24 hours. Along the way, I caught a butterfly with my hands (swallowtail, same coloration as those at Caracol) granted it was dead.

Some cool things observed on the hike:

– flock of green parrots that made noises like stormtrooper bullets

-toucan

-THE endangered Morelet’s tree frog! It was adorable!

Morelet’s Tree Frog, endangered species!

I managed to catch a good number of bugs in my pit fall traps—1 beetle, 6 ants total. It’s strange to think that these animals drowned to death in my urine.

We ended the day with lectures on ants, amphibians, and visual and auditory communication in rainforest animals.

Later that night, I was in bed when I was called to the restroom. A moth had fallen onto Bella’s head while she was on the toilet. It was rather large with a wingspan of around 13cm and had the coloration of a speckled yellow leaf. I removed the moth from the restroom and let it crawl around my shoulder. Although moth coloration is limited in vibrancy in comparison to butterfly coloration, I still found the yellow moth incredibly stunning. I have named it Sunshine. Sunshine kept falling off my hand and onto the wooden floor. Moths are hilariously clumsy creatures, falling off surfaces and bumping into them constantly. This may be attributed to their thick bodies. I can empathize with them as a fellow less-than-graceful creature.

17/05/19 Pit Fall Trapping

I had a rough night of sleep between rainforest bug sounds and some intermittent whooping, but I got breakfast at 7:00am as usual. The class discussed an experiment testing nitrogen limitation in the forest canopy versus nitrogen limitation on the forest floor using arthropods and pit fall traps, then we set up pit fall traps along the Maya Trail using water and our own urine.

Some cool, miscellaneous things observed on the hike:

-Blue Morphos spotted: 7

-I found a beehive. They are aggressive.

-We saw a cave entrance in the rainforest trail and summoned bats by kissing the back of our hands!

-zombie ants

-I caught a tiger longwing (Heliconius hecale)! (Mid-flight! I jumped to catch it!)

After lunch, the class visited the entrance to a nearby cave and saw the cenote from which Las Cuevas Research Station draws its water. While in the cave, I gave a lecture on the taxon Lepidoptera while the rest of the class listened and sat in bat guano. Then, Anna presented on Orthoptera and Pierce presented on Life in the Dark.

During the night hike, the class observed a different set of species from the set that we normally see during the day. I observed many moth species (such as the sphinx moth) instead of butterflies—however, the most exciting moth to see was the black witch moth (Ascalapha odorata). This bat-shaped beauty I found had a wingspan of about 15 centimeters (the black witch moth can grow up to about 17cm in terms of wingspan). While moths usually lack in vibrant coloration, the black witch moth had characteristic hints of iridescent purple and pink in the bands along the margin of the wings. Additionally, I observed that the moth had the characteristic 9 or comma shaped markings along the top middle of the forewings with an orange outline. I also held a stick bug, and a cockroach with a glue butt (his name is Elmer). Elmer was an astounding 6cm in length and hissed when touched, but overall a very friendly cockroach that crawled up my arm, my neck, my head, and left some of his butt glue in my hair.  I am excited to see what animal friends I can make tomorrow!

16/05/19 So. Much. Hiking.

I got a good amount of sleep, but awoke for 7:00am breakfast exhausted, which was unfortunate because we completed 8.6 miles of hiking today. We hiked down two trails—the first trail (it was very hilly) ran along the right side of the 50 hectare plot near Las Cuevas Research Station, the second trail was the Monkey Tail Trail.

Some cool miscellaneous things observed/experienced on the hike:

-Butterfly net doubles as a good hiking stick.

-I held an anole!

-I caught my first four butterflies with the net! One was a predominantly tan/brown swallowtail with iridescent purple spots on the forewing. What a beauty! The other three were pale green sulphurs.

Sulphur!

Swallowtail with iridescent purple spots

-Blue Morpho spottings: 5

-Closest distance I’ve gotten to a blue Morpho: ~1m

-Number of Blue Morphos caught: still none 🙁

-I made friends with a bee that sat on my shoulder for a portion of the trek.

-I wore a cicada shell like a badge.

-I ate a live termite and it tasted alright.

-I saw a large dragonfly (estimate about 15 cm)

-acacia ants

-spider monkeys

-I sat in a pile of ants.

-I adopted camera trap ‘Rice 2’. It is currently sitting along the Monkey Tail Trail about a 45 minute hike from the research station.

I observed that the most abundant species of butterflies in the area seem to be sulphurs (of white, pale green, and bright yellow colorations) and swallowtails (dominant black color with vibrant patches). Blue Morpho sightings were more frequent than I expected considering how well their undersides camouflage with their surroundings, but they were mostly spotted in flight. I am hopeful that I will succeed in catching a blue Morpho in the remaining days that the class will spend in the rainforest.

After a dinner of spaghet, the class ended the night with lectures on arachnids, epiphytes, and life in the rainforest canopy. Overall, a tiring and successful first day in the rainforest.

15/05/19 Cara-cool Ruins

I awoke to the sound of birds (or rather, people birding). After breakfast and mourning my last hours of reliable WiFi, I loaded the van with the class to travel an hour to Rio on Pools in the Mountain Pine Range. While there, we swam, but mostly slipped, slid, and stumbled on the algae that blanketed the rocks. We also dunked our heads in waterfalls. Once dried and changed, we embarked on another hour-long  journey to the Caracol Ruins.

At the Caracol Ruins, there were many butterflies that appeared to be of the same species (a variant of swallowtail as indicated by long ‘tails’ protruding from each hindwing).  The ruins themselves were magnificent, but also a pain to climb; the steps of the ruins were so high that every time I took a step, my knees rose to my chest. It was all worth it though because now I can say that I have conquered the tallest structure in the country of Belize! Also, I stood within a tomb, which was dank, and the buttresses of a ceiba tree. After traversing the ruins, the class drove an hour to Las Cuevas Research Station, our final destination for the day.

Some other cool, miscellaneous things observed en route:

  • Mayan temple replica currently being constructed by a man who claims to be a descendant of a Mayan god
  • 3 military checkpoints, the second of which was a Dutch army base
  • carsickness 🙁

At Las Cuevas, I found and captured a butterfly in the restroom. It was sitting with its wings closed (as is the tendency of the butterfly), so I identified it as a butterfly even though the coloration (lacking in vibrancy) was more similar to a moth’s. The butterfly was tan/brown with an eyespot on each wing (forewing and hindwing, 4 eye spots total). The hindwings had significant perforations, but they were erratic in size and depth, so I believe that they were not present as a result of species-specific characteristic.

It began raining lightly (forest’s namesake weather!) Scott heard then saw a scarlet macaw.

After dinner, the class ended the night with a discussion on research question, and lectures on trees, birds, and the paradox of tropical soils.

Day 8: Snakes don’t scare me

Today we left Las Cuevas early and the last meal ever at Las Cuevas. This morning I had eggs, bacon, tortilla, banana bread, pineapple, and pineapple juice! My favorite drink! As we were driving away at 7:03am, I took a last glimpse of the research station and closed my eyes for a nap.

The ATM cave is a living museum and it was soooo much fun! The water was cold, and as expected, I fell at one point in time. literally always falling!! Seeing lots of Mayan artifacts and even some human remains very well complemented my expectations and the overall cave exploration.  Who knows how long this extraordinary place will be around and now I can say I have been to the most sacred cave in the world!

The sodas here at Belize are so good and they are so much better at keeping plastic pollution down compared to back home. We have plastic bottles and aluminum cans for our sodas while here in Belize, it is all glass. The drinks are so cheap!! $1 Belize dollar ($0.50 US Dollar)! They reuse the glass bottles saving the plastic waste, and this helps the environment. 

At the Belize zoo, I saw every animal that I did not see at Las Cuevas, and the zoo made the rainforest portion of the class more fulfilling. I feel like having the taxa epiphytes, I see them everywhere. I was fulfilled as soon as we entered the Chiquibul on our way to Caracol, but seeing the crocodile, watching the jaguar do his somersault, holding a snake, and even feeding a tapir definitely fulfilled my expectations and beyond. I hate snakes, never liked them, but after holding boba, I can say some snakes do not scare me anymore. See you tomorrow as we travel to Glover’s Reef Research Station!

Day 2: Tour of the Caracol ruins

On the way from the Crystal Paradise Ecolodge to the Chiquibul forest and Las Cuevas Research Station, we stopped in two different places: Rio on Pools (in the Mountain Pine Ridge) and the ruins of Caracol, and ancient Mayan city.

 

At Rio on Pools I took several pictures of trees that I want to identify when I get a chance (during daylight hours, when I can read the field guide). Of course, we saw the Caribbean Pine, which characterizes the Mountain Pine Ridge. For anyone reading this who does not know the regions of Belize, a ‘ridge’ is a description of a general area/ecosystem and not an actual landform of high elevation. I spent most of the time taking pictures, alternating between the trees and my classmates.

The Caracol experience was more notable in terms of learning about the region. The first time Scott came on this trip, he did not go to the ruins, but local people told him that it was entirely unreasonable to be this close to the ruins and not see them. The palace at the ruins of the ancient Maya city is the tallest building in Belize, and from the top (of course we climbed it!) you can see Guatemala. We learned quite extensively about the Maya for a few hours (religion, culture, social structures).

We also saw tons of trees. Our guide pointed out the Kapok or Ceiba tree (Ceiba pentandra) and the fluff that comes from the seed pods that I think he said was used as padding, for example in a mattress. The tree also has huge buttress roots extending from the sides that serve several purposes, including structural support and nutrient absorption. [insert picture here]

We also saw today:

A few more trees at the Maya site: Cohune palm (Attalea cohune), Fishtail palm (Chamaedorea sp.), more Trumpet tree (Cecropia peltata), relationship with guarding ant species, a Strangler fig (Ficus sp.), and some Montezuma Oropendolas (Psarocolius montezuma).

Fishtail Palm, Chamaedora sp.

At Las Cuevas: a Cedar (Cedrela odorata), A Scarlet Macaw (Ara macao) and a Social Flycatcher (Myiozetetes similis).

We don’t have internet today because of the weather. It appears that the rainy season has started early this year. We will get to see how that effects the visibility of our focus species.

Day 3: Monkeys and the Monkey Tail Trail

Today we set up the camera traps for our week-long research project. We are testing the impact of the human disturbance at the research station is significant on diversity of animal species, so we will count species and individuals caught on the traps over the week. Setting up the traps involved hiking multiple trails in the area, so we saw a lot of wildlife.

This morning we hiked to a 50 hectare plot, which is an area marked for research purposes, to set up three cameras in that direction at 15 minute walking intervals. Onn the way there, we saw a mahogany and a fiddlewood tree, which were marked by the research station. In terms of trees, we saw Give-and-Take palms, another spiny palm called a Basket Tie-Tie, several Gumbolimbo trees, and at least a few Sapodilla. We also saw a small tree that I thought might be a Poisonwood tree, but it was too small to tell for certain. I was using leaf characteristics for identification—none of us were willing volunteers to test out the burning properties of the caustic sap.

On the same walk, we also saw spider monkeys for the first time. They remained high up in the branches, but hung around to look at us. It seemed they were as curious about us as we were about them. “Observe how poorly acclimated to the forest are these humans,” their tour guide could say. And that would be true, although Scott said we would find the hiking easier at the end of our stay here. We did not measure distance, but we spent a few hours in the morning and another few in the afternoon hiking out to place the cameras.

In the afternoon we hiked the Monkey Tail Trail. It was threatening rain, but we only got a few drops and a few distant thunderclaps. It is possible that the rain was captured higher in the canopy by epiphytes (some of these are known as airplants) or other organisms and did not reach us on the rainforest floor. The trees we saw on this hike included more Gumbolimbo. I could see why this was called the tourist tree. It is given the name because it is red and peeling like the sunburn of a tourist unaccustomed to the intensity of the sun here. It is also used locally as a remedy for a range of ailments from colds to gastrointestinal problems to measles to sunstroke. We also saw the Bull Thorn Acacia, which has hollow pairs of thorns in the shape of a bull’s horns which are inhabited by ants. The tree produces food and provides shelter for the ants in a way that induces the ants to defend the tree as they would any other nest. As a result, if you disturb the tree (especially if you break a thorn), you may be attacked by ants. This protects the tree from predators and describes a symbiotic relationship because both species involved benefit.

In addition to some interesting beetles, we came back from the hike with quite a few ticks each. Apparently ticks here don’t carry any serious diseases, but are mostly a nuisance. Picking them up today was the result of travelling an overgrown trail, and especially affected those who were not wearing insect repellant and/or were not trying as much to avoid brushing against the brush.

Note: We still have very limited wifi and may not be able to post at regular intevals.

Day 4: Getting Our Rainforest Legs

Scott said that after a few days of hiking in the rainforest, we would start to feel more energetic and less exhausted. This despite our full days. I think a few of us are starting to feel this. Today started with more bird watching, for everyone else. I slept through bird watching and went to breakfast at 7 instead. Right after breakfast and until lunch we set up an experiment to determine nitrogen limitation on the forest floor versus in the canopy by using human urine. Where did we get human urine? Guess.

We set up vials of urine and water along a straight trail every 200m. We also saw a cave full of what might have been Leaf-Nosed Bats, another Cedar tree (Cedrela odorata), and a Bay Cedar (Guazuma ulmifolia). Liz still has yet to catch a Blue Morpho butterfly, but we can identify them well from a distance. They are an iconic rainforest animal.

The bark of the Spanish Cedar (Cedrela Odorata)

In the afternoon we went to a cave and held the day’s lectures in it. The cave was home to an ancient Maya religious site, and walls and platforms built by the Maya for ceremonies are still standing today. On some platforms Mayan pottery remains. We also saw either swallows or some other bird nesting in the entrance. There were cave crickets and a millipede, and many interesting formations, in the cave.

In the evening we went on a short night hike (not too far from the station clearing) looking for night creatures. Much of the fauna of the rainforest is more active at night than during the day. We saw a Central American Tree Snake, lots of colorful beetles, moths, a scorpion, a tailless whip scorpion (not actually a scorpion, though an arachnid), leaf cutter ants, an orb weaver and some crickets. We also saw a Wolf Spider with its abdomen absolutely coated with little baby spiders. This stage does not last long, so we were lucky to see it. What we saw at first was a yellow shine where the eyes of the spider were and what looked like a huge abdomen with green glitter. Those were the eyes of all the baby spiders.
