Caracol & Las Cuevas

Today we completed our journey south-west through Cayo and into the Chiquibul rainforest. On our way to our home camp at Las Cuevas Research Station we took an anthropological detour through Mayan ruins. We were guided through the Caracol Archeological site and climbed up and in and down the ruins and tombs. Even though it was mostly overgrown and covered by years of sediment the pyramidal structures still stood and it was easy to image the bustling metropolis it was 2000 years ago. Hearing about the (hypothesized) reasons for its decline was ominous; overpopulation, agricultural collapse, drought… sound familiar?
Even though its citizens are long gone the city is still full of life. Almost everyone found an animal from their taxonomic group—bromeliads, philodendrons, birds, mammals, and a plethora of plants. The highlights included an edible red fruit (you suck on the seeds but don’t eat them, looks like gunk, tastes like papaya), toucans, a coati and a blue crowned mot-mot.
Sadly there were not any amphibians around for me to identify. The area was much too dry to be a suitable habitat. Amphibians require a damp habitat because they experience high evaporative water loss through their skin. Most also require water for reproduction. Caracal was in the forest but it was not dense enough to retain the moisture necessary for most amphibians. Here in the forest surrounding Las Cuevas should be a much more habitable medium and we can expect to see a variety of species in the next few days.

The beginning

Travel was smooth and breezy. It’s amazing to have everything all planned out for you so you don’t have to worry about transportation or lodging or food, I almost feel spoiled. Now I can worry about more important things- like tropical field biology.

We are staying at a beautiful lodge called Crystal Paradise and already have seem a surprising amount of flora and fauna, considering we’re not even in the jungle yet! In terms of amphibians there have been two cane toad sightings. I will try to get some pictures to share with you as we go on. There have been insects, arachnids, a large boa (I get to check that off my Belize wishlist now), and a plethora of trees and flora. The scenery was beautiful driving across the country, but I admit it mostly just looked like a bunch of trees and green stuff to me. I was glad for Sam’s lecture on the rainforest canopy, which was very helpful in starting to separate out the different kinds of plants and their relationship to one another.

Day 8

As per usual, something went wrong with the van. Our original plan for the day was to leave Las Cuevas early in the morning in order to make it to ATM cave for a swim and exploration. Then, we were going to drive across Belize to stay at the zoo. This is not how our day went at all.

Most of the morning was spent sitting on the porch, waiting for our van to show up. This went on for several hours. Rather than spend all our time waiting, we got the opportunity to tour other parts of the Las Cuevas research station and learn about their ongoing projects.

When our van finally arrived, we all climbed gratefully into its semi-air-conditioned space. Unfortunately, our massive time delay prevented us from being able to visit the ATM cave.

However, we did end up going on the night tour of the Belize zoo. Not only did we get to see two of the eighteen jaguars that they have, but we got to see margays, ocelots (so noisy), two types of owls (Rice!), a tapir, and three kinds of snakes.

Overall, I remain optimistic about the rest of the trip. Each thing that goes wrong does not faze our group at all. The new challenges that the reef will pose to us will be just new bonding experiences for us.

 

Pre-departure fugue

The night before a big trip never phases me the way it should. I pack, I sleep, and the next day I find myself somewhere else and just roll with it. I always feel like I lack the appropriate level of enthusiasm (whatever that it), but it beats travel anxiety so I don’t worry about it too much. The enthusiasm returns once I’ve settled in, and all is well. I worry and pick over everything else but travel is like “well, I guess I’ll get there somehow.” Perhaps this is some kind of physiological adaptive response to environmental stressors…

I look forward to returning to Central America in biological pursuits once again. During my 5 week conservation trip in Panama I really only worked with two species– Loggerhead sea turtles (Caretta caretta) and Hawksbill sea turtles (Eretmochelys imbricata)–so the breadth of my experience is limited (a generous way of putting it). I feel like I’ve barely skimmed the surface of all there is to know tropical field biology. I’ve read all kinds of books and primary literature, looked at pictures and diagrams, even experienced it first-hand in some of my trips abroad but it still feels like I know squat. There is just too much cool stuff!

Speaking of too much stuff, fingers crossed that we don’t encounter anything I don’t have on my taxonomic ID cards. Annelids and hydroid identification is fairly simple, but amphibians are a whole other story. There is clearly one very good way to avoid detection by predators because there are some pretty similar-looking frogs out there. Also I worry that some of my sources may have been a bit dated (2000 isn’t that long ago, right?). I tried to mentally absorb as much information as I could from a bunch of sources in the hope that some of it will be useful. Despite all this I genuinely enjoyed reading about amphibians even though I’ve never had any particular interest in them before. I look forward to developing even more new interests during this trip.

Day 7

On our last day at the Las Cuevas Research station, we spent most the morning and afternoon retracing our steps from the first day. All of this was in the effort to understand if species richness differed between natural and man-made clearings. I am proud to say that the hike was not nearly as exhausting as it was at the beginning. I also got the change to see an example of epiphytic Encyclia cochleata, the national flower of Belize. I think I have achieved my peak of epiphyte. It was one of the most satisfying moments of this trip to date.

After cleaning up and showering we went over to the classroom for taxonomic presentations, my presentation on NTDs/ethnobotany, and to look at what our camera traps caught. I really enjoyed my topic, especially because I had taken a research seminar in the previous semester on the topic. We then got into an interesting discussion on how Brazil should manage the threat of Zika and the upcoming influx of people for the Rio de Janiero Olympics.

Our pictures from the camera trapping experiment were a bit disappointing until we got the last one. On its memory card, we found both and ocelot and a WHAT WAS THIS. Overall, our data set was way to small to be able to really tell anything about the preferences of animals in the Chiquibul for man-made or natural clearings. All in all, these past experiment (while they don’t yield statistically significant data) are doing a great job of showing me how to trouble shoot ecological/evolutionary experiments.

On to Glovers Reef!

 

Day 6

Today was not a great day for epiphytes. This isn’t because they weren’t out there, but just because we spent most of the day inside. Our main project was to interpret the results of our pitfall traps. After collecting the vials, we headed back to the classroom to assess the morphospecies found. Our hypotheses focused on whether species abundance and richness were different in the canopy versus the forest floor and whether or not canopy species were more attracted to a nitrogen source (our urine).

The first question was more straightforward than the second. We could clearly see that both abundance and richness were greater for the forest floor. However, teasing apart the question of nitrogen limitation in the canopy versus the forest floor proved to be much more complicated. In the end, we choose to represent the difference between the by creating data points by subtracting the amount of arthropods in the water from the urine (for canopy and ground). Upon discussing the report with Scott and Adrienne, we found many ways in which our work could be improved upon. Two of the most crucial changes we made was to use a proportion rather than a subtraction and to pool all samples we took (broadening our community). This refining process is both interesting and productive; many new research directions came from our discussion.

At the end of the day, we all went on a night hike. The difference in number of species we saw was really noticeable. As for epiphytes, I certainly saw them, but am becoming more and more convinced that this group is hard to pin down for any specific geographical location. So many of the factors of what species ends up where is tied to the specific characteristics of the niches of the Chiquibul forest. In the future, I would be interested took look into the literature for information on niche exploitation by epiphytes. I think it would greatly increase my comprehension of the epiphyte landscape.

Day 8: The bus saga continues…

This morning, we got up early for a final hike before our 7 AM departure. At 7:30, the bus still hadn’t arrived. We called to discover that the bus hadn’t left yet, and was 4 hours away. We were scheduled to tour the ATM cave in the morning, but by the time we arrived we had missed our spot and wouldn’t have made it out of the cave until 7. To make matters more exciting, our bus driver decided that he was dropping us off with all our bags at the cave, and wouldn’t drive us all the way to our hotel as we had originally thought. We got a new bus driver, and stopped at a souvenir shop and ate lunch at a restaurant. I tried tamarind juice for the first time and it was delicious!

Then, we drove to the Belize Zoo. We went on a night tour of the zoo, which was amazing. All of their animals are native to Belize, either rescues or animals in rehabilitation. We got to see jaguars, ocelots, pumas, and margays that we’ve been living with all week in the forest, but never actually seen. We got to feed a tapir named Indie, who was confiscated as a baby from the pet trade. We also saw an adorable pair of pacas, which are large rodents with similar size and coloration to baby tapirs. Pacas are hunted for their skin and meat, and hunters often accidentally shoot baby tapirs while hunting pacas.

We didn’t do much hiking today, and I didn’t see any termites. Tomorrow I’ll be giving termites a rest and searching for red algae!

Day 7: Our final chiquibul adventure

Chiquibul

Today we collected the camera traps that we set out on the first day. It took us 10 hours to set out the traps the first time, but today we were done by 3 while taking a substantial lunch break. It’s amazing what a week in the jungle will do.

I didn’t see any new termite nests today, as we were walking a path we had travelled several times and didn’t stop much to poke around. We did, however, see some amazing species on the camera traps!

The first photo we looked at contained a bird, but most of the following pictures only captured leaves moving and people walking by. After sifting through hundreds of photos from 11 traps, we had seen 2 birds and a tapir. The tapir was awesome, but I think we had all been hoping to see more than 3 species. We weren’t expecting much from the 12th trap, which we had accidentally set up on top of a massive leaf cutter ant nest. To our surprise, this trap caught an agouti and an ocelot!! Those last photos definitely made the 26 miles of hiking worthwhile. We’ve heard about all of the species in the Chiquibul, but it was so incredible to see these species (almost) in person, and know that they crossed the same path that we did sometimes only an hour before.

Tomorrow morning, we will leave Las Cuevas. I’m covered in heat rash and I’ve been perpetually sleep deprived, but I feel so complete when I’m here. I have loved waking up to the sound of the howlers and being surrounded by the buzz of the jungle. I’m going to miss this place, but I know many amazing adventures await us on the reef!

When vans are less reliable than big cat sightings

This trip has seen a variety of transportation mishaps, but today took the cake. After a final morning walk, we were all set to leave for ATM cave at 7am. However, the van was not, as it had not even left its starting point, which was hours away. So we had some nice time to talk with other group members, get a presentation out of the way, and have lunch.

Finally the van appeared around noon and drove us to Georgeville, where we were to meet our tour guides for the ATM cave. However, upon arriving at the town, it became clear that it was too late to go to ATM cave (plus the bus driver wanted to drop us off and leave), so we instead stopped for lunch at the Orange Gallery, and then headed off (with a new driver) to the Belize Zoo.

The night tour of the Belize Zoo was one of the coolest things we have done so far. We got to each feed a tapir named Indy, and see two pacas, a Morlet’s crocodile, and many other species.

However, the best part of the zoo tour for me was the cats. We got to see four of the five species of cats that inhabit Belize (the jaguarundi is diurnal and thus was not out). We met a black jaguar named Lucky Boy, a very vocal ocelot, a small puma of the Belizean variety, a margay with ankles that can rotate 180 degrees to climb down trees, and another jaguar who did tricks. The Belize Zoo is an amazingly natural place that not only rescues individual animals, but also uses these individuals as ambassadors for conservation. Their pride in their natural heritage was truly inspiring!

Final Forest Feels

Today we took on the 14-mile hike to pick up the camera traps that we put out on Wednesday. We picked up seven traps before lunch, and five traps after. This time the trek went significantly faster and was much easier, though my full-leg red rash reappeared. I’m really hoping this won’t be a recurring issue in the future.

A few different species of mammals were seen today, most of which were caught in the camera trap images. Though I did not see it, apparently an agouti was seen by others in the group during morning bird watching. Some really exciting species were caught by the traps. Another agouti and an ocelot (!!!!) were caught by the same trap in a naturally open area, at different times. We also got a great picture of a tapir (endangered species) along a human path. Though the sample size of species in our camera trap images was small, all of this was still super exciting for me, especially the ocelot capture.

I also gave my mammal taxon briefing in the evening. This was my favorite of all the presentations to make and give, and I really enjoyed watching others using some of the information from my presentation in attempting to identify species in the camera trap images.

It’s pretty sad to have to leave this place. The rainforest is magical in the amount of life it holds, and even though I’ve barely slept all week, I’ve felt as strong as ever here. Hopefully I can return some day!
