As I type this up, I have swatted away 15 bugs of different sizes, including two true bugs from my bright screen amid the dark screen. I think two are about to battle out for the space or try feeding on my screen (they’re debating). 

I literally cannot believe we’re already 4/14 of the way into our trip. To be fair, it’s only the second day in LCRS, so we’ve still got a ton of time, but that’s already 28% of our trip! It’s been so so fun getting to know everyone and their tasks along our trip. From Sam’s ant catching to Dyllan’s butterfly trapping (always so close, it’s really really hard though), to Claire C’s insane ability to spot anything from a mile away. And also, Elise can tie super crazy knots (figures she was an Eagle scout). But we’re only getting closer as we complete more and more projects together. And today, we had two of them!

But not to get ahead of myself! First, at 6 we saw a group of parakeets–it was so cool to watch them fly above in formation. There were also a lot of bright green parrots and something called Morelet’s seedeater… makes me think they eat seeds lol. They were this really pretty shade of brown though I loved it. After this, we had a yummy, yummy breakfast of fryjacks with eggs and beans. Miss Angie has never missed on a meal, like plate scraped and everything. Now would also be a good time to mention the dishwashing station. There are three areas, a bin to scrub your plate with soap water, one to rinse off the water, and one with a mild bleach solution. We all wash our plates and utensils, and throw out any food scraps. While we did have sinks and stuff, this is actually a pretty similar system to one I use in India visiting my grandparents. All scraps need to be composted because they won’t be drained otherwise. And all food is washed outside to prevent insects from potentially entering indoors. But back to the point. 

After breakfast, we got to working. Dr. Solomon taught us about pitfall traps. These are super useful to collect specimen in understanding the abiotic factors of the rainforest. One of these is nitrogen richness in the canopy vs. the forest floor. With the sheer mass of leaf litter, soil-breaking organisms, and roots on the ground, much can vary between this area and the canopy, which is dense, and often quite isolated. This includes nitrogen content, which can really change the mass of producers, and thus herbivorous and predatory invertebrates along the forest floor and the canopy. To understand these dynamics and how they varied species biodiversity and abundance, we decided to place a nitrogen source and regular fluid in the pitfall traps. We would add these to the base of trees to capture forest floor dynamics and the tree trunk to get the expansive canopy above. And what better trail than the 50 hectare plot. Funny enough, each spot was about 50 ft away from the other. Coincidence? I think not…

Ok, ok, but what was our nitrogen source? If you’ve read any of the other blogs, don’t spoil it. OK.

…pee? 

Yup! And so the process began. We were actually really speedy with the setup. And obviously, as the best person ever, I was first to go (we ran out of vials, and long story short my very makeshift pitfall needed to be placed quick). But it was really a cute setup. And writing coordinates and marking spots, we were done in time for lunch!

One beautiful stirfry rice later, it was time for our second experiment of the day. A key characteristic of plants in the rainforest are their symbiotic relationships with insects. And one unique one is the Cecropia Tree and Cecropia ant. These ants burrow deep into the Cecropia, making multilevel chambers to lay their pupa in, gaining nutrition from the numerous extrafloral nectaries (little knobs on the tree surface). In return, the tree get’s protection from the ants against other herbivores. 

We wanted to test out if there was more that was keeping the herbivores away from the tree. As ants habited the tree, did the tree physically and chemically change? To solve this mystery, we needed leaves from an uninhabited and an inhabited Cecropia tree. We would also need several general herbivores to compare this. 

So off we went to the San Pastore and Las Cuevas Roads, hunting for both Cecropia and herbivores. But first off, (the royal) we caught to big, green katydids for each group. They were literally right there, and massive skill from Serenity, Dyllan, and Claire C. really paid off. Bug and leaf hunt time!

My favorite frolick yet. Remember those bright red nymph/beetle things from yesterday? We saw so many of them and it was giving herbivore so we stuck them all into one bin to pick apart later. Then, we were off on a cricket and grasshopper hunt. And Ian was really put to the test today with all of these species. I’d never caught bugs before this and it was a brain chemistry-altering experience. Crouching below, getting them with my bare hands, it was so fun. At one point I caught what we thought was an ant but turned out to be a tiger beetle, which is a lot more bitey and a lot less fun. Eventually, we got a high rise of the bugs. I like to think they were all like roommies back at the dorm, some better than others. Speaking of bitey though, we got to see a tarantula exoskeleton! They’re super hairy (the hair is a defense tactic!) and their fangs are a glossy black. It was so interesting to hold, because you know the tarantula is now bigger than this exoskeleton (a bigger shell of itself, one might say).  

Tarantula exoskeleton!

Also though, we got to cut open a Cecropia. It was so insane to see the layered chambers, as I’ll add below. And also, there were tarantula holes on the base of these trees. Crazy stuff. Try and try as we could though, we couldn’t get the young, uncolonized Cecropia. That is, until we literally walked 10 feet into Las Cuevas Road. And there it was, ready for Claire C. to spot it. Legendary stuff. Punching the leaves with a penetrometer to test physical resistance was definitely the most satisfying part of it all. I can’t wait to see how our insects do as we collect biomass of the leaves they eat tomorrow. But yeah, check out the leaves below!

What a fun, tiring day. I got to present my topic lecture which was fun. I did have a lot more info than I thought and had to skim through it, but I hope it was decent! Also, some fungi/lichen updates! Today was kind of a slow day. I got to see some more Dirinaria in interesting places. Also, there was a Turkey Tail right at the end of the 50 hectare plot. It was like a reward (after the long day of potting up everything). Plus, my first few termite mushroom of the day, with hollow, funnel pileus and white coloration. And a really interesting one, Claire C. spotted a series of black shelf fungi on a high up tree. I couldn’t tell you what it was, but I would love to climb it and find out at some point.

P.S. Speaking of climbing, check out this vine I swung through. #gains #tarzan #allnatural #cleangirlaesthetic

More to come!
