Cages installed and predators collected

All the mussel bed squares now have cages! Now I just have to hope no one will bother them. I'll put out signs and contact information at the next low tide. I can't wait until the low tides are in the daytime.

An experimental unit. Five snails will go in here.

I just finished collecting all the predator dogwhelks to be the treatments for my caged mussel beds. They came from three different sites around central and southern California. Now I just need to finish measuring and labeling them and put them in the cages!

Here are some photos during a post-collection hike at one of my central California sites, Soberanes Point in Garrapata State Park.

Field experiment installation

My mussel bed field experiment is coming together! This week I went out each day around 5 am to count what organisms are living in each of my plots and drill holes around them so I can install cages as soon as my cage material arrives. Here are some pictures of my work this week.
