Ottawa Panorama
The sun rising at the mouth of Crane Creek in Ottawa National Wildlife Refuge. Old mussel and carp enclosures sit in the foreground, and decomposing water lotus wilts just beyond the enclosures.
No luck
My soapy-water pan traps were not very effective.
Newly filled enclosures
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!
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.

Utricularia

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