Mating season

There seem to be too many plants and animals for me to memorize and learn.  I lack knowledge of entire groups of organisms – from what they are, to their ecological roles.  I won’t even mention organisms in Domains, such as Eubacteria (although I just mentioned it…), but insects and plants are phenomenally diverse, even in Ohio, and I am overwhelmed with it… I need more time – well, that, and a bit of patience to actually look at the insects and plants.  Little by little, I’m getting it, but in the mean time, I watch butterflies mate.

The Second-Wave of Mosquitoes

The mosquitoes are getting out of control. Walking through parts of the wetland, I litterally have difficulty seeing my feet, not because they are underwater, but because there are thousands of freshly emerged mosquitoes dodging my boots.

It seems that this is the second generation of mosquitoes, with the first potentially being left-overs from the dry season.  It’ll be interesting, to say the least, to experience the exponential growth.

Pupa exuvia are concentrated in small pockets of open water.

Decomposition-in-a-bag

site-e1-decomposition-bags-06012009-101805 I’ve set out 200 mesh plastic bags to examine decomposition rates and changes in litter chemistry of four types of litter: freshly killed Eichhornia crassipes and Typha domingensis (or dominguensis depending on what paper you read), and the past seasons accumulated litter from both aforementioned species. The bags sit, baking in the sun, attached to 3-m poles of PVC, which actually may be too short given the height of Typha (cattail) around here. The two photographs of bags below show some test bags I set out a few days ago, with tadpoles skimming around the surface of the bag… potentially attempting to enter and process the litter themselves. The other photo is designated site E1.

By the way, check out the excellent sewing job on the bags below… I can pump those out at a rate of 50 in 4 hrs now, although I started out at a much slower rate.
