How Where You’re Born Influences the Person You Become

As early as the fifth century, the Greek historian Thucydides contrasted the self-control and stoicism of Spartans with the more indulgent and free-thinking citizens of Athens.

Today, unique behaviors and characteristics seem ingrained in certain cultures.

Italians wildly gesticulate when they talk. Dutch children are notably easygoing and less fussy. Russians rarely smile in public.

As developmental psychologists, we’re fascinated by these differences, how they take shape and how they get passed along from one generation to the next.

Will insecticides targeting EAB harm woodpeckers?

Will insecticides targeting EAB harm woodpeckers?

This is unlikely. Woodpeckers feed on live, mature EAB larvae, mostly in late fall, winter and early spring. Many of these mature larvae overwinter in the nonliving, outer bark where they will not be exposed to systemic insecticides. Imidacloprid, dinotefuran, and emamectin benzoate are much more toxic to insects than to birds that have been tested, and insecticide concentrations that have been measured in treated trees are far below the levels known to be toxic to birds. An EAB larva that has been killed by insecticide will desiccate quickly and decompose. There is little evidence that woodpeckers will feed on larval cadavers. Furthermore, living larvae that are suitable prey for woodpeckers will not have been exposed to a lethal dose of insecticide, and these products do not bio-accumulate in animals in the way that fat-soluble insecticides such as DDT do. In Michigan and Ohio, where EAB has been established for several years, many ash trees have been treated with systemic insecticides. There have been no reported cases of woodpecker poisoning caused by insecticides applied for control of EAB.

Death Rates In The U.S. During Pandemic Far Higher Than Other Countries

Death Rates In The U.S. During Pandemic Far Higher Than Other Countries

Overall deaths in the United States this year are more than 85% higher than in places such as Germany, Israel and Denmark after adjusting for population size. Deaths in the U.S. are 29% higher than even in Sweden, "which ignored everything for so long," Emanuel says. Sweden made a point of refusing to order strict social restrictions and never went in to a full lockdown. "We have 29% more mortality than we should have if we'd followed Sweden's path and Sweden virtually did nothing."

Even looking just at confirmed COVID-19 deaths, the number of people dying since May 10 — again after adjusting for population size — is on average 50% higher than every other country in the study. In addition, the rate people are dying in the U.S. has stayed far above everywhere else. Emanuel says the current elevated mortality rates are important because they eliminate the chaotic early months of the pandemic when testing, treatment and reporting varied dramatically around the globe.

 

Increase in Woodpecker Populations Linked to Feasting on Emerald Ash Borer

Increase in Woodpecker Populations Linked to Feasting on Emerald Ash Borer

The scourge of forests, the emerald ash borer, or EAB, is usually described with words like “destructive” and “pest.” A recent study based on data collected by citizen scientists suggests that one more adjective might apply, at least from a bird’s perspective: “delicious.”

In a study published this week in the journal Biological Invasions, U.S. Forest Service entomologist Andrew Liebhold and Cornell University scientist Walter Koenig and others document how an EAB invasion fueled a population boom for four species of birds in the Detroit area.
