Pitfall Trap Analysis + Night Hike

Happy Sunday everyone! Today’s schedule was a bit different than those of our other days here. The morning began with a short hike along the Maya trail to pick up the pitfall traps that we had set up yesterday and analyzing our data. Specifically, we examined species’ richness and abundance on the forest floor and compared those values to the canopy’s. We also investigated whether there would be greater species’ richness and abundance in the urine vials relative to the water vials in the canopy as opposed to the vials in the forest floor. Interestingly, we found that both richness and abundance were higher in the forest floor than in the canopy and that the abundance in urine was greater than in water in both locations.

Many beetle specimens were collected today (10 species and 18 specimens to be exact) from our pitfall traps! A few of the most interesting were a fairly large beetle of about 3.5 cm long with a shiny black body rimmed with red that I believe may be a female pinching beetle (Lucanus capreolus), a very small slightly shimmery dark brown or olive green color leaf beetle (perhaps either a Dogbane Beetle with scientific name Chrysochus auratus or a type of flea beetle), and a black darkling beetle with a segmented body (species possibly Alobates pennysylvanicus).

As you can see, today was a fairly light day in terms of physical activity, but I am sure we will make up for it with the night hike tonight and especially with collecting all of the camera traps tomorrow. I am excited to see what animals are in the images we’ve captured (hopefully a picture of a jaguar?!?)! Thanks for reading! 🙂

Update: We got to hear from a Ph.D. student named Lauren tonight! She’s currently a little more than halfway through an eight month study here and is using 52 pairs of camera traps to conduct research on carnivorous forest creatures. Also, the night hike along the Maya trail was super cool! We saw tarantulas and other spiders the size of our palms, a cockroach the size of a large mouse, and a coral snake among many other species!

And I must end this post with a picture of a cool beetle from the night hike :)

“SNAAAKE!”

For our second to last day at Las Cuevas, we wrapped up our arthropod experiment by collecting all the pitfall traps set along the Maya trail yesterday. The majority of the day was dedicated to data analysis and the presentation of our results; there’s nothing quite like having a poster session in the middle of the rainforest.

We also spent a good part of the day discussing illegal extraction from the Chiquibul and the problems with conservation in Belize. I never fully appreciated the intricacies of conservation biology until today. The Chiquibul’s greatest threat is illegal extraction of plants and animals by Guatemalans from villages along the nearby border. Yet the issue of conservation is much greater than that of sustaining the area’s ecology and incorporates complex economic and political landscapes, as well.

Since our activities were primarily indoors, the day offered few opportunities for reptile sightings. However, I was excited at the prospect of our first night hike—the evening brings out a number of nocturnal species, transforming the Chiquibul into a completely different habitat than it is during the day. We managed to spot all kinds of creepy crawlies, including spiders the size of your face and a giant roach that emitted a sticky white substance. By the end of the hike, I had nearly given up on searching for reptiles in the leaf-litter and under fallen logs. But at the very end of the trail, we approached a sinkhole; as I peered down I heard a shout of “snaaaake!” I looked down to find the distinctive tri-color banded pattern of the Central American coral snake (Micrurus nigrocinctus) all but a foot away from my boot. The snake was small but could clearly be identified as one of the most venomous snakes found in Central America. Just goes to show that you can never stop looking.
