Panama Mangroves

Welcome! I (Dr. Maggie Toscano, Geologist) am about to embark on a field excursion to the Bocas del Toro province of Panama with several scientists interested in the mangrove environment and how it functions.

We will be investigating how mangroves grow and develop in the presence or absence of certain key nutrients, how mangrove crabs and other species use the mangrove trees, roots, and the peat they form as their habitat, and how mangroves respond to sea-level and climate changes over long periods of time (thousands of years).

We will be staying at the Smithsonian Tropical Research Institute in Bocas del Toro. Stay tuned for news, science and photos over the next two weeks!

Wednesday at Solarte

Weds. Nov. 10 – Today we went to the Solarte site, which was a dense dwarf mangrove that was particularly difficult to navigate (see photos).  Imagine walking in dark, knee-deep water tripping over unseen roots and seemingly impenetrable trees while carrying large buckets full of gear, and later, when you are hot and tired, buckets filled with heavy samples.  While it looks worse than it is, it takes a lot of time and patience and a huge sense of humor to do field work here, because a few trips in and out of the mangrove carrying these buckets can’t be done gracefully or in a hurry. You just keep clearing the trees gently out of your way while trying not to damage them as you pass, and trying not to trip or break your ankle when stepping into dark water where you can’t see the bottom.  While it may seem we are in a tropical paradise (true), we are still working hard in the heat and sun.  I’m just setting the record straight, not looking for sympathy, and I know it is cold back home!  This is incredibly interesting and challenging and I am very pleased to have the chance to experience this and learn so many things.  I’m a geologist working with biologists, and there is no better way for me to gain firsthand knowledge of these ecosystems.

Rhizophora prop roots hanging into the lagoon outside the forest.  The roots are an ecosystem all their own.  See the mangrove oysters and red fire sponge, among other species, that live only on those roots.

We had a nice dinner out in Bocas. We sat right at the water’s edge in an open-air restaurant where we ate coconut rice, fish with Creole sauce and veggies.  While we were eating a huge barracuda jumped out of the water and stayed where we could see it swimming near the dock.
