Hi friends,
Today before breakfast ended, Scott handed us two vials and told us to pee in them. What a great start to the day! It turned out that we will be using the vials as traps and we will be studying the preference for nitrogen and the abundance of organisms on the forest floor and the forest canopy.
We went out to put half of the vials into the ground and another half of them on trees. It went pretty quickly and we didn’t really get to see any organisms around that area because most of the trees had fallen from last year’s hurricane damage and the canopy was sparse.
In the afternoon we spent some time on the lectures before going out to dig for leaf cutter ants’ nests. This is Scott’s specialization so I was really excited to see what’s in store. He first brought us to a small nest that was about a year old. We quickly dug down to its fungal garden which Scott extracted using a teaspoon. The fungal garden looked unlike what I was expecting and it was cool seeing all the larvae being carried around on it as the worker ants try to rescue them as the fungal garden was being carried away.
The second ants’ nest was slightly bigger, about 4-6 years old, and it wasn’t that difficult digging into it either. When we got to the last one however, the first thing that surprised me was the size of it. From Scott’s description, it was about 10-15 years old, seemed to be about the size of 8 parking lot spaces, and it had multiple entrances. We started digging down from near the tree roots, as the nest was sloping from there and it was easier to dig. The soldier ants came out in no time to defend their home and they were significantly larger and greater in numbers than the previous two nests. It was a constant battle trying to excavate the nest and I was glad to have the rubber boots on as I could just shake the ants off as they tried climbing up my boots. I did get bit by an ant on each knee but the pants protected me well. It was a testament to their mouth grip strength that their heads stayed on attached to my pants even after I pulled off the rest of their bodies. Eventually Scott took charge and dug out the rest of the hill, but still did not find the fungal garden. He told us that it was probably because they decided to place their fungal gardens deeper to protect them, having their fungal gardens removed annually by Scott in the past few years.
At night after the presentations, Jordan, Deepu, Ellie and I decided to go tarantula hunting. We managed to find a couple of medium-sized tarantula holes and saw a few tarantulas that quickly disappeared back into their holes. We also found a roosting Common Pauraque through its eyes which reflected in our headlamps. That was pretty cool as it was camouflaged well in the leaf litter that it took us a while to figure out what it was.
After looking around for a while, we decided to go back to our rooms. However, we met Aimee from Loyola University who was just about to go find some spider specimens and asked us if we wanted to help her. Naturally, being the helpful and caring students we are, we volunteered to help. Before we did however, she decided to show us a couple of tarantula holes that she found. THEY WERE HUGE!!! And she showed us a technique to fish out tarantulas which was really awesome. We managed to get out some of them and took close-up photographs of them.
We then went into the forest (at night!!) and looked for a certain species of spiders under palm leaves. I managed to find a couple and I hope that this small contribution will help her out in her research work to document this new species of spiders. I want it to be named after me thank you!
As a side note, I didn’t see any mammals today which was disappointing. Maybe tomorrow!
Till next time,
Damien
