Long time no blog, eh? Well the internet cut out a few hours after my last post, and the only way we've been able to connect is by sneaking into the library that's supposed to be off-limits to us and hooking up. So guess where I am now...
Anyway, we finally finished our second project today. Again, here's the general idea in bullet point format, with the full version available to anyone who wants me to email it to them:
What we did:Stuck latex tags on 15 urchins (see previous post)
Tracked said urchins for three nights, going out every 2 hours
Mapped the resulting home ranges and found the range areas
Measured urchin size, number of neighboring urchins, and algal cover of each home range (urchins eat algae)
What we found:Larger urchins have smaller home ranges
Urchins with more neighbors have larger home ranges
Larger urchins have fewer neighbors
Algal cover doesn't affect range size
What we think might be going on is the larger urchins are better able to defend the better crevices and territories from other invaders and would-be usurpers. They drive off neighbors and get the coral head to themselves. Smaller urchins are forced to aggregate for safety against predators, and their home ranges overlap much more, forcing them to have larger home ranges so they can still find enough food. So basically we came out 0 for 4 on our original hypotheses - we predicted the exact opposites of those points listed under "what we found". Oh well. Our data is very convincing, so we're hoping to publish when we get back to the U.S.
But on to more fun things... On Saturday a bunch of us went to Papeete, on the main island of Tahiti for a day/souvenir trip. I split off from the giant horde with Romina and Betsy and we toured the city together.

Three of the four Moorea-Tahiti ferries in action. Sadly, ours was the fourth (the Aremiti 5) and we had to wait a little longer after I took this picture.

These are fresh fish for sale in Le Gran Marche (the big market). The next stall over was selling those very same rainbow parrotfish you've been seeing in a few of my pictures. The fish with the orange on their tails are
Naso lituratus, a type of surgeonfish we studied in class. Remember, one man's tropical fish is another man's dinner.

Betsy and Romina doing the cruise ship dance. This is the same ship that parks in Cook's Bay in Moorea, just down the bay from our station. It may or may not have been mooned repeatedly by certain UCLA students on various occasions by kayak.
Sunday we drove the trucks up to Belvedere, one of the highest points on the island accessible by car (or truck, in our case). The vista is rather spectacular and we all took a bunch of pictures of the whole north side of the island.

This panorama is made of six pictures stiched together on Photoshop. The version you see here is actually half the size of the original version (I had to shrink it so Blogger would let it upload). Go ahead and click on it to see the whole thing in all its glory (or try to find the seams - I'm getting pretty good, if I may say so myself). This picture is facing north. The bay on the left is Opunohu Bay, with Cook's Bay on the right. The Gump station is near the northwest point at the entrance of Cook's Bay. Note the large volcanic mountains (Moorea and all of the Society Islands were formed by tectonic hot spots, just like Hawaii) and the lush greenery everywhere. Very nice.
On Monday Wil and I decided to take a break from writing our paper and went kayaking over to the Sailing School (a few miles away, at the entrance of Opunohu Bay). The beach was full when we got there, so we started looking around for a place to moor our kayak without bothering the French people sunbathing on their yachts. While we were floating around, we saw some weird brown thing floating in the water. When we started paddling up to it to see what it was, it picked its head up and gave us the funniest look ever, and then the turtle dove back down. We jumped into the water to get a closer look, but the turtle disappeared completely. We still hadn't found a place to moor, so we started paddling out toward the reef. I saw a dead tree caught in the coral, so we paddled over, put on our masks and snorkels and hopped in. The flow wasn't too bad so we swam around a bit. Suddenly a black-tipped reef shark swam through the area. We swam after it so we could watch it, and more sharks started appearing. While we were floating at the surface, we saw about 7 or 8 sharks swimming around us (not the "I'm going to eat you" kind of circling - more the investigatory sort). One swam within 5 feet of me, but I made sure I was on the other side of a huge coral head for that one. I'm fine with sharks, and these were only 7-8 feet long, but it never hurts to be a little wary. We're definitely going to try to kayak back there one more time before we leave.
Speaking of leaving... We depart Moorea very early Saturday morning, and land in Los Angeles that evening. Certain roommates may want to consider having some kind of Welcome/We Missed You/We Could Barely Survive 2 Minutes Let Alone 2 Months Without You thing for us. Just a thought.
