Night Hike

Today we learned a valuable lesson in analyzing data. Statistics can help or hinder you and you must consider your question carefully to decide what kind of analysis to use. Different tests can give you different results, so you must be careful in considering your community and think about what will give you the most scientifically meaningful results.

After several lectures we took a short night hike and found spiders, cockroaches, insects and some people even saw a coral snake. The dry season has been particularly harsh and there is not much moisture, so I didn’t see any amphibians last night. They are probably hiding deep in the forest under the leaf litter or in other damp places.

Joys of the Jungle

I’m sitting at the back of the dorm building in the perfect temperature, listening to the sounds of scarlet macaws and watching everything turn a misty gold as evening rolls in. I love fieldwork.

Day 6 proved another successful day for mammal spotting. During another early morning walk, we spotted coatimundis just off the trail. At least two individuals were climbing and jumping through the trees, sometimes at spectacular heights. After some careful observation, we also noticed some Central American spider monkeys in a tree a bit further away. The monkeys seemed to be foraging, and their somewhat trill calls could be heard if we listened closely. We also heard Mexican black howler monkeys very close by, but did not see them. I swear that they’re taunting me.

While we spent a lot of time indoors today, we also learned a lot about scientific practice. After collecting the urine and water pit fall traps that had been set up yesterday, we sorted through the arthropods collected in them. I found many species of ants, a spider, a cricket, and a roach. We then calculated the numbers of species and individuals in urine versus water traps in both the canopy and on the forest floor. Depending on the statistical tests used, we got different results as to which community sought out the nitrogen-rich urine more. This demonstrates the importance of choosing the correct statistical metrics when analyzing data.

We are also doing a lot of lectures today in order to open up time when we head to the Belize Zoo in two days. Tonight, we will have a presentation by one of the researchers stationed here at Las Cuevas who is studying jaguars. I am really excited to meet her and hear about her work! We are also going to take a night hike later in the night. I’m hoping to see some mammals on this trek (or at least some eye shines), as many species are nocturnal.

I’m definitely in my element here.

Two Days!

As someone who came into Rice knowing exactly what she wanted her major to be, I have been looking for ways to work this course into my curriculum since the beginning. While my certainty in EBIO has never wavered, I am not a place to definitively say what kind of research I want to go into. That’s where EBIO 319 comes in. I expect that this course’s broad nature will give me a more comprehensive view of the field that I will eventually be going into. Do I want to focus on terrestrial or marine systems? Ecology or evolution? What specific system? These are questions that I hope to at least make some progress on. I also expect that I will be underprepared for the trip in some large way. On similar trips, I have found this to be true. I’m not too worried about this; everything works out in the end (and you get great stories!) I love going on trips like this not only because of their educational value, but because of how they bring the participants together. I fully expect that we will find the trials and tribulations of the rainforest and coral atoll material for bonding. I cannot wait to get to know these people better.

The last couple of days have been very hectic for me, as I’m sure they have been for all of my classmates. I think we are all feeling increasing pressure to have everything perfectly in order. Getting proper fins has been a particular struggle for me. I think that I might end up carrying them in my lap on the plane! While there have been many logistical hurdles to clear, I have also been preparing my knowledge of the country.  The book, while definitely long, has been a valuable resource in explaining the important biotic and abiotic factors in the region. At the same time, I don’t want to remain too reliant on the book to prepare me. Words can only do so much. I’m prepared to have many of my assumptions be proven wrong upon arrival.

In addition to hopefully providing some clarity on what I want to focus on in my EBIO curriculum, I hope that this course give me a immersive view into an ecosystem. After spending two years learning about ecosystems interactions from afar, I am excited to be right in it for two weeks. I think that this will greatly flesh out my current EBIO knowledge.

On the other hand, I am worried that I’ll get all of the way out there and be completely lost in the myriad of topics that we will be covering. It is possible that the breadth of the course will further my confusion on my specific interests. On the logistical side of things, it is very possible that I will forget something crucial (deodorant? pants?). Ah well, neither of these worries overshadows my overall excitement for the course!

I know that I am going to enjoy this trip. Travel is one of my favorite things to do and when combined with the subject that I love, I know that this will be an experience that will remember even when I have left Rice. A couple of years ago, I went on a scientific/tourist expedition to the Galapagos Island with National Geographic. While I was probably too young to fully appreciate the impact, it definitely peaked my interest in the biological sciences. Later on, I traveled with my high school to Peru for a more service oriented trip. Both trips to Latin America were great experiences. I am looking to continue this trend. In the end, I am most excited to simply be in Belize. I can picture myself waking up for breakfast, not in Martel College but in the rainforest/coral reef. The calmer moments before we leave for the day’s research will likely be what I remember most. Well that and the academic clarity I hope to find. I can’t believe it’s only two days away!
