Trapping a Jaguar!!! (On camera, hopefully) (Day 10)

Hi all, it’s Faith with Day 10 updates from the 2022 Belize trip!!!

Today we woke up extra early (mostly on accident) to birdwatch from Las Cuevas Deck! We didn’t see any macaws, but we saw two- four toucans flying across the sky. They were gorgeous!

Then we went to plan out next research project. For our question, we chose “which area (trails, jungle, roads) will each animal group (large predators, small predators, large prey, small prey) use the most measured by relative abundance?” Our hypothesis was that big cats would be the dominant animals using paths and roads whereas small prey and mammals would stay under forest cover. We planned on using trap-cameras to get photos of animals as they cross the trails. By the way, while we were planning, we saw 4 scarlet macaws flying around!

Then we set off to se tho the cameras. Our first trip out we ran into our first of three white lipped turtles (Kinosternon leucostomum). This one was easy to identify because of its white lip, it looked just like one of the ones on my taxa sheet, and we found it swimming in a muddy puddle after the morning rains. After we saw the turtle, I set up my first camera on the “shortcut path” back to Las Cuevas. Because I went first, I was deemed the “camera soldier” and had to fix/ mess with lots of peoples cameras.

We did so much in this hike: set up cameras, use gps markers, walk through the jungle, eat termites, climb a bird tower, trip on Mayan stairs, see huge cave spiders, the list is endless.

I didn’t see my taxa again until after a light evening rain, and they were two mud turtles swimming around in mud puddles. I’m finding that these turtles vary greatly in shell appearance and patterning. The last two turtles lacked the classic white lip coloring, which caused me to misidentify them at first. However, their “bridge shell pattern” between the carapace and bottom shell indicated their true species. Plus, they were found in the same environment as the other white lipped mud turtle!

I’m hoping to see other types of mud turtles, like the Tabasco turtle. The wet season is proving to be good for turtle hunting but bad for reptiles and snakes. I’ll let you know what we see next!

Til’ Tomorrow!

Rubber boots>hiking boots

Today was mostly one big recon mission to gather all the pitfall traps and camera traps we had set along the trails near Las Cuevas. We left at about 9 to gather all the pitfall traps, which involved cutting the wire we had used to strap the vial on the the tree, somehow unsticking the tubes from the ground, and of course, gathering all the flagging tape. This was a relatively short mission, especially compared to setting them up yesterday.

We got back to the research station, and began to collect our results and analyze our data. We didn’t finish the poster, so I’ll briefly explain what we found. Overall, we saw that there were more arthropods in the ground pitfall traps, and more arthropods in the the pee traps than in the water traps. This suggests that there are more arthropods on the ground than in the canopy, but that they are more attracted to nutrients.

our athropods!

We then left for the camera recon mission, which was also a shorter excursion than the one to set them up. We still have yet to look at the footage from them, but I’d image a lot of it will be pictures of us trying to set up and take down the cameras. Also, I don’t think I’ve mentioned this, but rubber boots are actually great for hiking!

I unfortunately did not see very many orthoptera today. I saw several small crickets, but they were too speedy for me to get a picture. One of them was really tiny, no more than 5 mm long. It was sitting on the dinning table, but it hopped away before I could invite it to stay and eat lunch with me.

I’m not sure how the next few days will look, but I will try to keep everyone updated!

Fungi-full Day! (17/06/22)

We woke up to the sound of howler monkeys and a ton of birds. I wasn’t planning on doing the 5:30 morning birding but I apparently had no choice since the birds were so loud. They have turkeys here! I had no idea, and the turkeys here are so much prettier than the turkeys at home, they have lots of cool colors. We also saw some vultures and Scarlet Macaws! There are so many birds in the Chiquibul, I had no idea!

After breakfast we started our question using the camera traps and decided we want to see what functional groups of animals are using which parts of the forest splitting up by trails, roads, and just the jungle. After deciding everything we went out into the jungle for the first time hiking! It was sprinkling when we left and it continued to rain on and off the whole day. Right away we saw a ton of lichen on trees, all crustose so far, and plenty of mushrooms! Unfortunately a lot of them weren’t on my ID card, and I’ve been told that the fungi here isn’t well recorded or published so it’s hard to find comprehensive information on everything we could see. Most of the mushrooms were tan and brown, relatively close to the ground and maybe a couple inches across, with a pretty flat top. The smaller mushrooms were more bell shaped and much smaller, less than an inch but had longer stalks. I did manage to identify some turkey tail mushrooms on logs since they’re shelf-like, and easy to tell apart from the shape and the stripes (which look like a turkey tail), and even some puffball mushrooms! The puffball mushrooms were super cool, they had already released their spores, and were covered in mud from the rain but still had a little puff left in them if you bumped them a little. I’ve seen those mushrooms all over tiktok as food or just a cool thing to find in the forest so it was so cool to see one in real life!

We also saw some slimes and possible jellies, none of which were the ones I had put on my sheet specifically but hopefully with the pictures I took I can try to identify them eventually. The problem is it’s hard to get a good look at some of them since the fungi are off trail oftentimes, or under logs (where snakes like to hang out) or near ant nests, or are just in awkward positions and I don’t want to touch mushrooms unless I know what they are. At least eating mushrooms isn’t an issue, I can’t stand the texture of mushrooms, so I can admire them from a distance and not worry about getting poisoned by some random mushrooms out in the woods. I do have a lot more respect for anyone who really knows their fungi and can actually identify species and safe versus poisonous types, especially since so many mushrooms have look alikes! I’m hoping tomorrow out in the woods we’ll find something new, since today the mushrooms got pretty repetitive, I have a lot of really cool colorful mushrooms on my wish list of things to see here, so hopefully we’ll have some luck tomorrow finding more!

We finished up the day with some lectures, unfortunately without lights we couldn’t actually write in our notebooks, however we did manage to come up with some good field biology DIY solutions!

Bug madness

I know I said yesterday was the first day in the rain forest, but today was the actual first day in the rainforest!

We started out the day by figuring out how we were going to conduct research with the camera traps. We decided to look at the abundance of different types of mammals on different passageways, including the main road, the trails, and forest. Once we had our methods figured out and a plan for which path to take, we were on our way! We set six camera traps in the morning-all five road traps and one trail trap. We returned to the station for lunch, and then set out for the afternoon to walk another trail and set the other ten traps (four more trail traps, five forest traps, and one for-fun trap at a pond). We were out in the rain forest from 1:30 until 6:15, which was absolutely amazing. We got rained on a bit (which is always exciting for me because I’m from CA), and the forest was super lush and full of so much life.

Sophia lost her boot in the mud

We saw a lot of amazing things. I actually saw a bunch of orthoptera, which I wasn’t entirely expecting, since they’re so good at camouflage. I saw some tiny crickets in the grass, possibly a pygmy mole cricket, and a small green katydid on the branch of a tree.

I saw a group of black grasshoppers with red heads on the branch of a small tree as well. I thought it was odd that they were in a group, as grasshoppers and other orthoptera are usually solitary. I also saw a small-ish brown cricket that looked almost like the the jerusalem cricket.

The most amazing orthoptera sighting for me was at night during the post-dinner presentations! I got to see a huge leaf mimic katydid (shoutout Michael for grabbing it for me)-it was probably about 3 or so inches long! In order to grab katydids, you have to grab their wings and their femurs because their back legs are so strong, they can push against your hand and make you lose your grip. We also saw a smaller katydid, maybe two inches long (shoutout Rusty for catching it). Both were a vibrant green, and their wings really did look like leaves! Too bad they were in a classroom, so their camouflage didn’t work so well.

Overall the day was jam-packed with excitement. We saw a bunch of other really cool organisms, such as birds, beetles, cockroaches, and ants, as well as countless trees and epiphytes that we had only just read about in the text book. We got to try eating termites (which taste sort of like carrots!), and we climbed to the top of a bird watch tower to see the amazing view! We also saw a cave that had maya pottery and a wall in it, and a giant leaf cutter ant nest, that was probably about three or four feet in diameter.

I can’t wait to see what tomorrow brings, since today the main focus was just setting the camera traps!

A Spectickular Day

Today, May 16th 2019, I had an early morning with 5:00 early morning birding. There was eerie mist surrounding the clearing and it was almost ominous to hear the jungle amongst suddenly come alive with bird calls. It started with the hoots of the Blue Breasted Mot Mots. The grey form of a Plumbious Kite flew into a tall tree and a pair of parrots flew overhead (flapping their wings rapidly and almost screaming) (this is completely normal and it looks like they’re panicking). Some Melodious Blackbirds and yellow breasted Social Flycatchers also made appearances. Perhaps the most surprising site was a Grey Fox slinking back into the forest at the edge of the clearing. The display that took the cake was the Plumbious Kite sweeping down from its perch to catch an insect and feed it to what I assume was its baby that was in a tree right in front of us.

After, we had breakfast and an orientation and we started our experiment. In short, we’re investigating if the presence of the research station impacts species richness and abundance at different distances from Las Cuevas using images from camera traps (movement sensitive cameras). First, we hiked up a 50-hectare plot, a rectangular plot (50 hectares in area), and after 45 or so minutes we placed our first camera trap. On the way, we saw so much life such as beetles and crickets. Excitingly, we saw a couple instances of mammal scat (feces) and a game trail (a trail created by a large animal running through the forest to find food). A good indicator of a game trail is snapped vegetation with a compressed path through the forest. On the way back along the trail to place some other camera traps we saw a troop of Central American Spider Monkeys dwelling amongst the canopy. They shook trees, a behavior used to intimidate, and used their prehensile tails and great climbing skills to follow us until we exited their territory.

 

We then hiked up a longer trail called Monkey Tail Trail to place more camera traps and saw many ants (some of which bit people) and attracted the attention of a multitude ticks.

 

With a long day of hiking behind us, we ate dinner and ended the day with presentations on epiphytes, arachnids, and an overview on life in the rainforest canopy.

 

Tomorrow we have a project to construct in the morning and may go on to explore a nearby cave which is exciting beyond belief.

Day 7: chant with me: ants! ants! ants!

Today’s general agenda: retrieve camera traps —> finish poster for project mutualism —> check out leafcutter ant colonies —> look at camera trap photos 

Here’s a missed opportunity: Ant-Man should really be Ant-woman instead

Did you know that if you see an ant on the ground, you are most likely observing a female worker ant? These ants are infertile ants that do many important tasks to keep the colony up and running. Male ants only appear during mating season. Today was definitely another fruitful day in the ant department.  In the early afternoon, we got to make a poster and present on our project focused on Azteca ants and their mutualistic relationship with Cecropia tree. We found that, on average, uncolonized trees have tougher leaves, meaning they are less likely to be eaten by herbivores. However, we definitely need more data to validate our results.

In the late afternoon, Dr. Solomon, the actual ant-expert, took us around the research station to compare leafcutter ant colonies of different ages.  We were specifically looking at colonies of A. cephalotes. These colonies can have millions of individuals residing in them, and they can be seen as one of the earliest farmers.These ants collect leaves to grow fungus, and the fungus is then fed to ant larvae. When aggravated, these ants can use their sharp mandibles and actually chew through rubber boots. It was a surreal experience getting to observe what I have been researching in preparation for the trip. 

leafcutter ant soldier!

As our grand finale for the rainforest, we all sat in the classroom to look at the photos the camera traps took over the course of the five days we were in Las Cuevas. We were all on the edge of our seats because we just were not sure what to expect. I think we can all agree that the best picture that was taken was of a tapir walking on the path. On that note, I think we are all ready to further explore Belize and head to the coral reefs.

As a mid-trip reflection, I am already amazed by how much we have learnt in such short amount of time. Even though I was initially worried about having minimal internet access, I think the disconnection allowed us to be fully immersed in our environment. I

Day 3: and they came out of nowhere!

Today’s agenda: Las Cuevas research station —> exploring trails and setting up camera trap —> Las Cuevas Research Station 

Part of our trip objective is to conduct a research project around Las Cuevas Research Station. Our group came up with the plan to examine how the research station itself may serve as a disturbance for species diversity around Las Cuevas. To give some context, we are currently in a circular shaped clearing surrounded by the rainforest. We think that as we move farther away from the research station, we will see more diverse animals in numbers and species. 

We are using this technique called camera trapping where we pick certain locations and set up a camera to take pictures of anything that moves in front of it. I am hopeful that we would be able to spot some big cats (jaguar or puma) because on our way to our first camera trap spot, we saw what appeared to be some recent paw print on the floor.

Speaking of travels, we hiked a total of 5 hours today, climbing up and down hills. With our field gear on, we were able to explore the rainforest in-depth. We saw spider monkeys, blue morpho butterflies, spiny orb weavers, Xaté fishtail palm, and so much more! In the ant department, we spotted army ants, Pseudomerymex ants, Dolichoderus ants, and fire ants. Somehow, twice today, I had ants all over me. One even bit me under my shirt. These ants are not so forgiving when you come across their nests. Oh, and did I mention that I also ate a termite, but we’ll just have to save that story for another time. 

At the end of the day, after seeing almost something from each taxonomic group that each of us had, we ended up finding ourselves with either a few ticks or maybe 100 of them! They came out of nowhere! Turns out, ticks are hard to kill. To effectively kill them, you have to use your nail on one finger and press it against your other finger so it effectively cuts ticks in half.

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.

 

Excavation of small leafcutter ant colony

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!

Day 7: Upping the Ant-e; Las Cuevas Sends us Off in Style

Today was as crazy of a last day as we could’ve hoped for. I woke up at a luxurious 6:45 since I couldn’t do the bird tower hike with the rest of the gang because of my knee. Once they came back we ate dinner and reconvened to start picking up the camera traps we set out 4 days ago. We went along the Monkey Trail, Saffron Trail, San Pastor and 50 Hecatre plot to pick up our traps. Along the way, we saw a brown anole and a golden turtle beetle, both of which were really cool. I also saw a harvestman of the same round body species that I’ll have to look up and an unidentified species of orb weaver spider.

A Leaf Cutter Ant Queen

We came back, ate lunch, and spent a little time catching up on notebooks and listening to music on the deck. We met up with the group from Southern Mississippi to go on leaf cutter excavations, led by the one and only Scott Solomon. He led us into the Monkey Trail where we spent some time excavating the 1-year old nest. After digging around the hole for a while, we were able to see the fungus chamber and extract the fungus ball and the queen ant, which was enormous. We walked along saffron to the giant leaf cutter nest from before, where we spent a while excavating the side of the hill. The Southern Mississippi group left for dinner, but we continued excavating until we ran into the garbage disposal chamber and felt the heat from the decomposing trash they had left.

We came back, showered, and had dinner before heading to the activity we were the most excited about: checking the camera traps. Everyone tried to have low expectations, but it was obvious that we had high expectations. In the first camera traps alone, we spotted a tapir and a jaguar before coming across herds of peccaries, curassows, a 9-ringed armadillo, a coatimundi, two pumas, another jaguar, a rat, a snake, and a lot of photos of ourselves. I don’t think I’ve ever been more excited flipping through photos on a screen. All of us were extremely surprised and really excited about the results that we found, even though our initial hypothesis about off-trail sights being more rich, abundant, and diverse was incorrect. After that, we worked on our blogs and packed up to prepare for saying goodbye to Las Cuevas.

Arachnids found: Orb Weaver of an unidentified species on 50-hectare plot on a web with striped legs and a green back. Large wolf spider in the leaf litter that scurried around, looked like the Allocosa family. Florida Bark Scorpion, under the stairs of the lecture room with babies on her back. Another Florida Bark Scorpion on the deck of the dorms, froze when we got close.

All Bark No Bite

Day 3: We Got a Few Ticks Up Our Sleeves

I woke up bright and early at 5:15 to bird watch, where we saw oropendolas, a flock of Red Lore parrots, and a friendly bee that loved Elena’s hair. All these sightings were pretty expected but were really cool nonetheless. We ate a nice breakfast of eggs, beans, and journey cakes which I didn’t really eat because I’m still feeling a little queasy. We went up to the lecture hall and Scott gave us a briefing on Camera Traps. We had a quick discussion on some ideas for the traps and, after a long deliberation, we decided on testing how the presence of trails affects mammal presence and abundance.

An Orb Weaver Spider Web Chilling in The Trees

We set off on our hike at 9:30ish and headed down the Monkey Trail, up the Saffron Trail and then down the San Pastor road. Along the way, we ran into a boa constrictor chilling on the forest floor and a huge leafcutter nest, which gave all of us a jump. We came back for lunch, ate some rice and plantains, and headed back out on the 50-hectare plot. We set up our last two camera trap pairs and spotted a zombie ant on a fern. We came back, I showered quickly, then Rafael M. director of the FDC gave us a talk on the conservation efforts on the region, which was really fascinating. We ate dinner and headed to the lecture room for talks, which I gave on arachnids, Elena gave on ants, and Claire gave on the Paradox of Tropical Soils. Afterwards, we all headed to the dining room to work on these blogs!

Arachnids spotted: a wolf spider in the leaf litter of the Saffron Tree-unidentified species; Wolf spider mother on San Pastor Road, spotted by Adrienne with eggs on her back; Unidentified red mite on breakfast table; Many many chigger bites on Veronica, Jessica, and Adrienne (RIP); Almost everyone got a tick bite, including me, under my watch – they hurt; Red Rumps in the clearing by the lecture hall that scurried back into their holes after they saw us.

Can you spot the spider?

All of these are expected, unfortunately, but still really cool.
