On the road

On Wednesday we traveled from San Jose to Guayabo National Monument and then to Earth University. On the way, we saw black vultures.
We started to see lots of plants with ephiphytes growing on them. These plants derive nutrients from the rain and the air. Biology students, what kind of a relationship do the tree and the ephiphytes have?
Don't try to get a bunch of teachers to jump in the air at once. It just doesn't work.
Here's a typical lunch for a vegetarian. It's called pinto gallo and it's rice and beans and here I have a salad made from a cukecumber like plant that grows locally. I also had mashed plantains, which are a like a starchy banana. I think the last dish was potato.
Here's a hog nosed viper that I saw in Guayabo. I wish it were a better picture.
This is the work of leaf cutter ants. I hope to do an entire entry on them at some point because they are really cool!
This is what the countryside looked like. There were many small farms. The road was very, very windy and I came close to getting sick. It was an extremely long day of travel to get to Earth University, so I was relieved to arrive.

  1. I think the epiphytes and the tree have 'mutualism' or 'commensalism'? And what are those kind of red/brown flowers?

  2. The epiphyte and the tree's relationship is commensalism because the epiphyte benefits by gaining nutrients from the atmosphere and the tree neither benefits nor is harmed!

  4. I think snakes are my least favorite animals on earth. Was the hognose viper poisonous? If so, I don't blame you for the picture...I probably wouldn't have stayed long enough to get my camera out.

  5. Wow! That plant that had been demolished by the leaf-eater ants was crazy. That would be cool to learn about those ants some more. Great pictures!

  10. That lunch looks really good! and those coke bottles would be vintage in the US. You should bring one back. Just kidding... Commensalism relationship because the ephiphytes don't take nutrients from the tree.

  11. I can't really see the snake. But from what I can see it's one weird (but interesting) looking animal. What allows for all the different plants and animals to thrive in Costa Rica?
