La Selva Recon

Authors: Aaron, Erin, Rachael, Rob Collins

Word of the day: Secondary succession-  process of regrowth that occurs in an area that has recently been subject to disturbance. There are several types of disturbances that result in the destruction of an ecosystem, such as floods, forest fires and other natural disasters. These disturbances provide new fertile ground for a new generation of vegetation.

Example of gap succession, a type of secondary succession that occurs after a tree falls.


Science of the day: Today we performed a reconnaissance hike in preparation for tomorrow's sampling. As we traveled through the forest we were able to distinguish between areas of primary and secondary succession. Our main focus of our testing tomorrow is the comparison between old growth, new growth and transition forests.

Although we observed a lot of biodiversity yesterday, we were also able to identify many new species today, which included the green and black poison dart frog, a mating pair of great curassows, a troop of white-faced capuchin monkeys, and peccaries.

After our recon hike, we ate lunch, showered, then divided and conquered in our groups. Some groups worked on species identification at the La Selva library, others analyzed soil samples in the lab, and others caught up on writing journals, reading, and organizing data.

Today's Culture: We received a question asking the following, "Latin music and dance is so very romantic. How do men and women interact? What kind of roles are traditional."

Salsa music and dancing comprise a subculture of their own. Tradition dictates that the man always leads and the female plays the part of the subdued partner. Its acceptable for both men and women to change dance partners many times. Salsa had its heyday from the 70s to the mid 80s where people danced salsa at all types of different events. Currently, salsa has changed its image and has become increasingly meshed with rock and hip-hop. The traditional dance steps are still popular with the addition of newer hip-hop influenced moves.

Question of the day: Why are the tropics so hot and humid? One of our group member's dive watch even said "ready to dive" because it was so humid out!
