A Spartan-led research team has uncovered an answer — at least for the most recent population decline — with a huge assist from volunteers.

Michigan State University ecologists led an international research partnership of professional and volunteer scientists to reveal new insights into what’s driving the already-dwindling population of eastern monarch butterflies even lower.
Between 2004 and 2018, changing climate at the monarch’s spring and summer breeding grounds has had the most significant impact on this declining population.
In fact, the effects of climate change have been nearly seven times more significant than other contributors, such as habitat loss. The team published its report today (July 19, 2021) in the journal Nature Ecology & Evolution.
“What we do is develop models to understand why monarchs are declining and what’s happening to biodiversity in general,” said Erin Zylstra, the study’s lead author. Zylstra is a postdoctoral researcher in the Department of Integrative Biology and the Ecology, Evolution and Behavior Program, both in MSU’s College of Natural Science.
In fact, corn has traditionally been a symbol of life and fertility, particularly among the native peoples of the Americas, so I was delighted to see how artists and designers realized corn’s ripe possibilities in a variety of contexts.
Possibly my favorite is this musically inclined fellow composed of corn cob, leaves, and tassels (a composition that simultaneously demonstrates the rich linguistic play the word corn offers–I didn’t appreciate until I read the description that he is playing the cornet!):
At the time of this writing, at least 120 people have been confirmed dead because of severe flooding in Western Europe.
It is tragically likely that, when this story is over, the number will be significantly higher. A German weather service (DWD) spokesman told CNN that in some areas there has not been this much rainfall in 100 years.
These extreme weather events are inextricably linked to climate change, politicians and experts have noted.
But there is another culprit, one above, that is also affecting the weather: a “wobble” in the orbit of the Moon. Indeed, only days before the flooding, a study in the journal Nature Climate Change by scientists from NASA and the University of Hawaii warned that the Earth may experience record flooding in the mid-2030s because of changes in the Moon’s orbit.
The growing number of Baby Boomer retirements nationwide is accelerating, raising concerns locally about losing a large chunk of the workforce sooner than expected.
Data shows nearly 6 million more Boomers in the U.S. retired from October 2020 through March of this year than the same period a year prior, creating a larger void than anticipated in an economy seeking to fill jobs across an array of industries and recover from the woes of the coronavirus pandemic.
A trip to America’s national parks once meant packing a tent or finding the nearest roadside motel.
Indeed, in the mid-century heyday of the road trip, it was part of the charm.
But as park visitors have become more diverse, and more discerning, over the decades, so too have the surrounding accommodations. Today, travelers can choose from desert bungalows with private plunge pools, five-star hotels with room service, or chic cabins with outdoor rain showers — all in close proximity to open spaces and natural beauty.
