Hola mis amigas y amigos!

My Peruvian friends have been telling me that the last few months have been very dry, so I had no idea what to expect upon my arrival. I was very surprised to see that the Amazon River was at least 30 or more feet lower than when I was here in March, which could potentially have a huge impact on what amphibians we see. Areas where there would normally be ponds could be completely dry. As you can imagine, I couldn’t wait to get out into the rainforest and see what may be waiting for us.

Unfortunately, my suspicions were accurate and amphibians were much harder to find than usual. Since we monitor some of the same areas year after year, I had a pretty good hunch on where and what I might find in certain areas. When we have time, we always check other areas but our priority is to first survey our research sites. Among many other pieces of data we have been collecting, we are looking at diversity and abundance of species – basically, what types of frogs and toads and how many. This year seems to be the most obvious change, likely, due to the dryness. The humidity levels even felt different – normally my skin stays moist but this time I was using lotion.So far, the most interesting or peculiar sighting was a toad that had climbed a tree. The toad, common to South America, was at least four feet off the ground with no visible easy climbing point. I can hardly wait to see what else we may find!

Buenos noches!
