citizen science

Russell’s book got me thinking about who is it that is doing citizen-science, since much of science is still dominated by white males, and to a lesser extent white females. It would seem that a positive attribute of citizen science is that it should remove most of the academic/economic/social (i.e. college degree) obstacles to participation in natural science, and thereby possibly appeal to folks from all walks of life. Indeed I did find several references to this while cruising the internet looking at citizen-science projects. This Hudson River Eel Project sounds particularly cool to me (cooler than tiger beetles). Here is a NYTimes op-ed about the project – well-worth a read.

In related matters, the other evening I saw entomologist Doug Tallamy (author of “Bringing Nature Home“, excerpts of which we will read later) speak about the ecological impacts of non-native plants in our home landscapes. Much of his data has been generated on his own 10-acre property, and he mentioned that he runs a citizen-science project, where people submit pictures of birds with insects in their bills, and he identifies the insects. It turns out that caterpillars (rich in protein, fats, and carotenoids) are really important in the diet of songbirds during the nesting season, and if there are no native trees and shrubs, there are very few caterpillars to be had, and thus few birds. Sounds like another version of Silent Spring? Here’s a description of his project.

Rivers Connect Us – and some pics

Hi guys and gals, if you check out the American Rivers link on the Moodle site, you may notice that the subtitle of their logo says “Rivers Connect Us”. Think about that idea as you are pondering the other “things to ponder” on page 3 of the trip handout. Does nature connect us too? BTW, the American Rivers logo used to say “Thriving by Nature”

PS dont forget to include Categories in your posts (for this one I selected Water and Rivers)

My kids found this lying on our flagstones early this summer. It is large (more than 2 inches across), very light, somewhat furry, and beautifully marked. Interesting enough to spark some family curiosity. We dug around a bit on the internet, and discovered that it was the hindwing of a Polyphemus moth.

And some related interesting facts:
silk moth decline?
why eyespots?

I also found out that any caterpillars feeding on tree leaves (i.e. many butterfly and moth caterpillars like that of the Polyphemus) are killed when the “organic” pesticide Btk is sprayed to control gypsy moths. Gypsy moth is an invasive species from Britain that was introduced with the intent to develop an American silkworm industry. Now it is a big nuisance, periodically causing mass defoliation of eastern forests. Next year is apparently going to be a big year for damage in eastern PA

Here is a nice animation of the spread of the gypsy moth west and south from Massachusetts in the 20th century.
