Bare limestone is covered in lichens, bromeliads, and orchids where there is sufficient moisture. These ‘hatchlings’ may be the same species I found flowering/fruiting in June. Although I posted a photograph of the flowers, I wasn’t able to find the post… I’m over the 300 mark.
Only two students braved the wetland last weekend when a large group of student came to Palo Verde from UNA (Universidad Nacional). I hope that’s not the case for the folks coming with Kent State this December…
Fed and Silvia were interested in counting ‘utriculos’ or bladders on Utricularia, but I convinced them to examine Neptunia nodules instead.
With much help, I’ve filled a new set of enclosures for another competition experiment. This time, I have varied both initial density (8, 16 and 32 plants) and proportion of the two species. I’ve also repeated decomposition bundles within the enclosures, although the picture here doesn’t include them. The density manipulation can be seen with this photograph, though.
Hesperidae (skipper butterflies) are the Thalia herbivores, according to Tim, an IRES student currently studying termite behavior at Palo Verde.
I’ve observed both swallows (barn swallows + another I’ve yet to identify) and fly catchers (Great kiskadee and maybe another smaller species) capturing the hesperids.

One of two species of floating aquatic ferns at Palo Verde, the leaves of S. minima are extremely small and are covered with dividing setae.
Now, who knows the family of the bug surveying the Salvinia?
What is this goop? It feels like Jell-O.

Are dry forest wetlands nutrient poor? If not, why are there carnivorous submergent macrophytes, such as Utricularia gibba, and nodulated legumes (Neptunia prostrata)?
