Modern agriculture

Emily Helliwell explains her approach to talking with creationists. In short, focus on the concepts that are important to the here and now:

If we want to get back to the dinosaurs, we can say the cumulative effect of billions of years of changing environments have allowed for some pretty amazing creatures to come and go. But, let’s resist the urge to talk about that, and stay focused on the small-scale stuff. Because if there is any concept necessary for our modern, developed society to believe in and understand, it’s microevolution.

Through microevolutionary principles, we would not have developed two of the most important contributions to society, antibiotics and pesticides. Without antibiotics, we would be subject to horrible infections, and without pesticides, we would be subject to devastating crop failures. Many of us would be dead or suffering.

From our most recent nest box monitoring report, with some photo annotations:

this morning's wetlandA quite pleasant morning on the wetland.

Win some, lose some: Box #84 is hatched out, and Kat and Chris found WODU ducklings in box #2. It’s possible that a Wood Duck is starting a second clutch in box #6, with 2 eggs laid there recently. So for the season, that’s 13 of the 16 boxes with nests, and 6 nests that have fledged so far.

On the downside, it appears that boxes #1 and #3 were predated by snakes: the boxes are not messy inside, just empty, and there is mud streaking in box #1’s pole that could be snake-caused. These are the 2 new boxes bear the observation tower, the ones that don’t have predator cones.
Let’s meet again on 22 May and check all the boxes. Based on what we find then, we’ll make a plan for at least one day in June, perhaps two.

in the handcloser lookWe got some looks at the Barred Owl adult and owlets; newly-observed birds for the season were Acadian Flycatcher and Northern Rough-winged Swallow; migrant Pectoral Sandpiper and other shorebirds. Chris turned up a wee American Toad near the vistors’ center.

NEW

The Economist‘s recent leader in favor of a revised metric of economic well-being is rather refreshing, surprising. Among the steps that it recommends be taken to improve on the slavish following of GDP, the piece leads with improving the measurement of what is already measured. But then the editorial pushes into measuring quantities that have never been systematically considered before: income inequality, negative externalities (like pollution), depletion of natural capital, and perhaps most importantly, the role of unpaid services like homemaking and caregiving. There are still other aspects of welfare that should be accounted for (e.g, crime rates, time lost to long commutes), but if we were to formulate a new metric along the lines suggested, it would be a big step in the right direction,

From my most recent report on nesting activity:

12 of 16 boxes with nests, and one more with adults seen in the vicinity! As of 1 May, boxes #10 (Hooded Merganser), #6, #13, and #62 (Wood Duck) have hatched out, more or less in the usual proportions.

Birds noted on 10 April: Glossy Ibis, Eastern Phoebe, Eastern Kingbird. Birds noted on 24 April: Common Yellowthroat, Eastern Towhee, Red-eyed Vireo, Lesser Yellowlegs, Chimney Swift, Barn Swallow, Green Heron. On 24 April, Houstonia sp. was in bloom near the end of the berm. There is a Tree Swallow nest in the broken top of a maple, down along Barnyard Run, near the “helper log” that lies across the channel near box #61.

We’ll meet again this Sunday, 8 May. Let’s skip checking box #7.

Bleached

Oh, dear Fox, yes: Stop Saying ‘I Feel Like.’

This is what is most disturbing about “I feel like”: The phrase cripples our range of expression and flattens the complex role that emotions do play in our reasoning. It turns emotion into a cudgel that smashes the distinction—and even in our relativistic age, there remains a distinction—between evidence out in the world and internal sentiments known only to each of us.

Jug Bay herps

Our first field trip for Rachel Gauza’s herps class took us to Jug Bay Wetlands Sanctuary in Anne Arundel County. Our host guides were Mel Fegler and Mike Quinlan. This is a popular natural place on the Coastal Plain, and rightly so. I heard my first Wood Thrushes of the year in the parking lot.

first one for meBut the focus today is amphibians and reptiles! In the morning, we worked several spots near the McCann Wetlands Center. Mike found an Eastern Wormsnake (Carphopis amoenus) under a coverboard in the meadow adjacent to the center.

woodydry nowMoving into the deciduous woods along the Middle and Forest Trails, we saw a nice selection of herp diversity: Eastern Box Turtle (Terrapene carolina), Wood Frog (Lithobates sylvaticus), American Toad (Anaxyrus americanus), Fowler’s Toad (A. fowleri), Marbled Salamander (Ambystoma opacum)—and one toad of doubtful status that I want to follow up with Rachel on.

in the cupnot JeremiahWe dropped down from the right of way of the railroad that once ran from Seat Pleasant to Chesapeake Beach into the floodplain of Two Run Branch to visit several seasonal (now dried) and persistent pools. Opportunities to see Marbled Salamander larvae, Eastern Cricket Frog (Acris crepitans), and a choice-sized American Bullfrog (Lithobates catesbeianus). Marbleds breed in the fall and the eggs overwinter, giving them a head start in develop come spring, so (as you can see), they’re already well along the way to becoming adults.

At lunch break, back at the center, I heard a Summer Tanager (Piranga rubra), and I think this is the first time that I’ve heard the call that Dick Walton’s tapes taught me so long ago as “piki-tucki-tuck.”

seasonalin the netIn the afternoon, Mel took us to a seasonal pool on the the Glendening Nature Preserve section of the sanctuary, the pool known locally as Barn Pool. We did some sweep netting through this pool, in a very rough approximation of the sampling protocol that Mel follows when she’s monitoring. The water levels were quite reduced, but there were many Marbled Salamander larvae to be netted.

The Nether

The titular Nether of this dystopian play is an immersive cyberspace where anything imaginable—legal or otherwise—is possible. Its weakness is the condescending script: for some reason, the old saw that pornography leads technological advances is trotted out. A police detective, investigating improprieties in the Nether, has precisely one verb to play: to hector.

A cloudy plexiglas box encloses the set in early sequences, causing significant audibility problems for us in row E.

The dismal enterprise is lightened by Jared Mezzocchi’s dazzling projections and the performance of Maya Brettell as Iris, a fantasy avatar.
