A couple of panoramas of a nice, open water wetland at about 400 m.

Heterostyly in Eichhornia
Eichhornia crassipes is another plant exhibiting heterostyly (genetically determined differences in length of the flower’s pistil and stamens between individuals), but there are supposedly three morphs in the species (tristylous). I’ve only encountered the two shown below, but they are frequently found nearby one another (within a few meters).
Damsel fly
Areli
I don’t know how to spell her name (maybe it’s Arelli, Arelly, Arely or something completely different), but she’s a Nicaraguan women assisting Mahmood with his frog traps. She’s currently away, but will be returning next week for more work. I believe she wants to go to graduate school, eventually, but that’s also hard to tell because all of my conversations with her have been in Spanish. I’m still learning, but she’s been helping quite a bit.
Diversity effects on decomposition
Here’s a big post illustrating a decomposition assay I recently set out in the wetland. I created bundles of dead, dried macrophytes in various mixtures, attached them to 3-m of nylon rope and tied the rope to posts in the wetland. I’ll be collecting a sample soon and may post another sequence.

Wetland Casa Vieja
A magnificent tree towers above yet another cow-infested wetland.
Another Wetland

I have yet to see a wetland that wasn’t directly impacted by cows. If there are any in Guanacaste or another part of the dry forest, it would be interesting to see plant and animal community differences.
Wetland Hacienda Jerico
One of the wetlands sampled during my trip with Rubén.
Azolla microphylla
A floating, aquatic fern, Azolla microphylla is in Palo Verde, but not very common. It seems to like open water habitats, since the only time I’ve seen it here was in open water, and it was very abundant at this lagoon.
