Noted: Some species’ hindmost legs can grow so long that competing suitors will line up to compare them. “Whichever male has the longest leg wins, and it’s the one that is going to mate,” Guilherme Gainett, a developmental biologist at the University of Wisconsin at Madison, told me.

Some answers might be hidden in the harvestmen genome. Gainett and Sharma, of the University of Wisconsin at Madison, recently teamed up with the genomics expert Vanessa González, of the Smithsonian National Museum of Natural History, to cobble together the first-ever draft of the genome of Phalangium opilio, the world’s most widespread harvestman species.

Noted: Fascinated by the way these appendages develop differently, Guilherme Gainett at the University of Wisconsin-Madison and his colleagues teamed up with genome specialists at the Smithsonian Institution in Washington DC to draft a sequence of the genome of a lab-raised harvestman.

“We’ve shown… how the combinations of these genes create a blueprint in the embryo to differentiate between what’s going to be a leg that is used for walking and what is going to be a pedipalp, which can be used to manipulate food and assess the surroundings,” says Gainett.

Noted: “Karl Polanyi for President,” a 2016 article in Dissent that Konczal coauthored with Patrick Iber, is a useful companion piece to Freedom from the Market, and helps illuminate the intellectual genealogy of its arguments.

As Konczal and Iber explain, Polanyi’s most famous work, The Great Transformation (1944), is devoted in large part to a critique of the idea that the so-called “free market” is a precondition for, and guarantor of, freedom more generally. “Polanyi’s work dismantles this argument in two important ways,” they write, first by showing that “markets are planned everywhere they exist.”

Noted: The idea, first put forth in a 2012 paper by Jennifer Francis, now at the Woodwell Climate Research Center, and Stephen Vavrus, at the University of Wisconsin at Madison, is that two well-established trends — Arctic amplification (intensified global warming at higher latitudes) and depleted sea ice — can force the polar jet stream to dip farther south, thus causing more intense bouts of winter weather than might have otherwise occurred.

Noted: In July, University of Wisconsin scientist Adrian Treves and two colleagues concluded in their new study that the population of gray wolves in Wisconsin is significantly lower than estimated by the DNR. While the DNR made claims about how the February trophy killing season would not cause much of a change in the overall wolf population numbers, mass slaughter during the middle of the breeding season would indeed have a significant impact on the population. This study shows that the population of gray wolves in Wisconsin in April likely falls between 695-751 rather than the far fluffier projections presented by the Wisconsin DNR.

Quoted: Adrian Treves, a professor of environmental studies at the University of Wisconsin-Madison who has studied wolf-hound conflicts, found that neighboring Michigan, which has stricter hounding regulations, has seen far fewer dogs injured or killed by wolves. Lighter regulation in Wisconsin means more dogs in the woods, Treves said, which leads to more conflict. “Houndsmen prefer to hunt in a place that lets them do what they want to do.”

In an analysis published in the journal PeerJ on July 5, researchers at the University of Wisconsin-Madison (UWM) estimate that Wisconsin’s wolf population was reduced by about one-third between April 2020 and April 2021. Specifically, the researchers estimate that 313 to 323 (27 to 33 percent) of the state’s 1,034 wolves were killed by hunters or poachers in that period of time.

And even that is likely an underestimate, according to Adrian Treves, study co-author and professor at University of Wisconsin-Madison. “We took the most conservative estimates of poaching and cryptic poaching,” or illegal hunting that goes unrecorded, he says.
