bromeliadThe search continues! We are searching high (literally) and low for more bromeliad invertebrates to finish off our experiments. One week to go until I add the remainder of my communities and then 2 week until I find out if any of this actually worked! Jana is at the same point and would like me to ask if anyone has any larvae of Dytiscid beetles lying around? She still needs for and we think maybe they’re on to us and have all jumped ship!Lisa and Helen are absolute life savers – staring into trays of sludge from dawn until dusk helping us find what we need! Jana and I don’t know what we would do without them!Tomorrow is the start of a bit of a break from science – we’re heading to Santa Rosa station for a night and then trekking the 12 km to the beach at Naranjo. Lots of people, cafeteria, remote beach, and sweltering heat… here we come!

Stand back, I’m going to try science!

Not only is the Costa Rican life pretty sweet – work actually gets done too!  My two experiements (Leaf packs to measure decomposition rate, and communities to measure effects of diversity on predation and decomposition) are all up and running! I’ve claimed nearly every bromeliad within a 1 km radius of the station to stick experiments in.  Now back to searching for more critters so I can replenish things in 2 weeks. 

I was going to include a picture of my experiment, but it actually looks identical to the header photo of this blog! A common site here at Pitilla – bromeliads with plastic tubes with mesh hats sticking out of them. Field ecology is weird.

ALSO – I’m very curious about what is happening back in Vancouver! Have Jana and I suddenly become the sole members of the Srivastava lab?? Where are the posts from home?

THE RAIN IS HERE!!

Just a quick note to say that it is now actually the rainy season!  We’ve had a couple of good nights of rain and the bromeliads are less bone-dry!  Woo!  Unfortunately that now means working in the rain some of the time but it’s worth it to actually have the critters live!

Speaking of critters – we’re gearing up to put our experimental communities together in the next couple of days. Today was a final push to find the damselfly larvae we need and we found 36 in one day! Woo!

And as a final note – I found the cutest snake you will ever see in a bromeliad today. A little Imantodes sp. (blunt headed snake) that was about 20 cm long and curled up on my hand. His name is leonard. Pictures to follow.

Pura Vida!

Who stopped the rain??

Here it is, a week into our field season in the rainy season in Costa Rica… and we’re in the middle of a drought! While it was nice for a few days to have sun and beautiful weather for working, it is becoming concerning. Even the rangers at the field station say they have never seen an October like this! All of our bromeliads are drying out which makes finding our aquatic insect larvae challenging, and we are having to actually go and water them to hopefully maintain some kind of community.

Hey, maybe if I can incorporate “climate change” into the title of my paper I can publish in Nature! 😛

What a morning!

When Diane asked if I wanted to go down to Santa Cecilia this morning to pick up the *new ATV’s* (!) I obviously jumped at the chance! (You mean I get to go ATVing for half the day and still count it as field work??) So off we went, both on the old ATV that I can’t change gears properly and takes herculean strength to turn right. After a very bumpy 25 min ride into town, we pulled into Cali and Petrona’s housed to see 2 gorgeous new Yamaha ATVs parked in the yard. What a beautiful sight! The ride back up to town was one of the funnest things I have done in a long time!  Racing up the dirt road which was bone dry after 3 days of no rain, plowing through mud puddles in 4 wheel drive…  WHEE!!  And that wasn’t even the highlight!

We stopped part way up to collect some dead leaves off a fallen tree for decomposition experiments and heard some grunting a little ways into the forest. That’s when we spotted the troupe of howler monkeys just 2 trees away! There were about 5 or 6 of them, including one youngster. We watched for about 10 minutes as they just hung out, moving between trees and munching away.  One of them came right out to the nearest tree and was watching us right back!

We finally tore ourselves away from the monkeys to return to the task of ripping down the dead branch.  Which involved climbing on a fallen log and jumping up and down, disturbing all the underbrush. After rather unceremoniously dismounting from the tree, I saw that we had disturbed a tarantula! It was actually pretty cute, about 5 cm long with brown furry body and black furry legs.

The rest of the ride up was uneventful in terms of wildlife, but what a ride! Under clear blue skies with a clear view of the volcanoes, tropical forest to the sides, and dry yet exciting roads – I was actually laughing to myself as we went and hoping that every day I find something to make me that happy!
