Trees, Knees, and Other Deep-Freeze Creaks

January 20, 2023 by Paul Hetzler 1 Comment

Conifers in winter courtesy Wikimedia user Olga ErnstIn winter, when temperatures dip well below zero Fahrenheit, especially if they fall precipitously, things go bump in the night. Frozen lakes and ponds emit ominous groans, snaps and booms that reverberate through the ice. Wood siding and old knee joints might creak. And if soil moisture is high and snow cover sparse, the soil can freeze deeply, causing the earth to shift in a harmless, localized cryoseism, or “frost quake” that produces a nerve-rattling bang.

Yule Logs & Firewood Science

December 23, 2022 by Paul Hetzler 1 Comment

illustration of people collecting a Yule log from Chambers Book of Days (1832)The tradition of burning a Yule log has largely fizzled out in most parts of the world. While holiday cards often feature cute, picturesque birch rounds in the hearth, old-time Yule logs in 6th and 7th century Europe were monster tree trunks that were meant to burn all day, and in certain cultures for twelve continuous days, without being entirely used up.

Santa’s High Reindeer & Alice in Wonderland

December 3, 2022 by Paul Hetzler 1 Comment

Amanita-muscaria-courtesy-Wikimedia-user-OnderwijsgekIf not for a fungus, Santa’s flying sleigh would be grounded. If that were the case, the only toys he could distribute would be to the elves who made them in the first place, which kind of spoils the whole surprise element.

The truth is that Mister Claus relies on Amanita muscaria, a mushroom which grows among pine and birch, to zip around the world on Christmas Eve. [Read more…] about Santa’s High Reindeer & Alice in Wonderland

November 4, 2022 by Paul Hetzler Leave a Comment

While it’s normal to think the quest for mouth-watering faux meat is a recent trend, it dates back almost a thousand years.

According to first-hand written accounts, European religious and political leaders in the Middle Ages and early Renaissance period spent decades searching for meat substitutes. [Read more…] about Beyond Meat: A Short History of Vegetable Animals

Echidna: Half Porcupine, Half Anteater, Sort Of

Short-beaked Echidna courtesy Wikimedia user JJ HarrisonWhile I usually cover flora and fauna relevant to the US Northeast and southeastern Canada, every so often, a non-regional subject whispers to me that it’s endlessly captivating and deserves an essay.

Eventually I comply to make the whispering stop. Please don’t tell my shrink about this. [Read more…] about Echidna: Half Porcupine, Half Anteater, Sort Of

Tree Slime: Harmless & Beneficial

September 24, 2022 by Paul Hetzler Leave a Comment

bacterial-wetwood-symptomsCast members of the new Ghostbusters film aren’t the only ones getting slimed – trees sometimes get slathered in slime flux as well. Many kinds of trees are subject to sludge assaults, with elms, apples, oaks, maples, and walnuts being among the more vulnerable species. Tree-goo, unlike the Psychomagnotheric Slime in Ghostbusters, is basically harmless. In fact, it can be beneficial. [Read more…] about Tree Slime: Harmless & Beneficial

Reading Bug Tracks on Tea Leaves

September 17, 2022 by Paul Hetzler 2 Comments

tea plant courtesy Wikimedia user James SteakleyFrom palm-reading to watching Fox News, humans throughout the ages have sought knowledge through some decidedly irrational means. But every now and then, superstition pays off.

For example, studying the pattern of coffee grounds in the bottom of one’s cup, a practice known as tasseomancy, will nearly always reveal that someone forgot to put a filter in the coffeemaker basket. And haruspicy, the study of the fresh entrails of a gutted animal, is consistently right in concluding the animal is dead. [Read more…] about Reading Bug Tracks on Tea Leaves

Understanding Early Fall Tree Color

September 10, 2022 by Paul Hetzler Leave a Comment

When income dips down to equal the cost of doing business, a wise proprietor will turn out the lights and lock the doors until spring. [Read more…] about Understanding Early Fall Tree Color

Yellowjackets: A Primer

As summer wanes, the original queen in every yellowjacket wasp colony dies – having a few thousand babies in the course of one season is enough to tire any Queen Mum to death.

The Secret Language of Mushrooms

August 26, 2022 by Paul Hetzler Leave a Comment

Amanita-muscaria-courtesy-Wikimedia-user-OnderwijsgekLewis Carroll’s Alice in Wonderland was chock-a-block full of whimsical characters such as a hookah-smoking caterpillar and a bloodthirsty Queen of Hearts playing-card. Although animals and some objects in the story are able to speak, somehow the idea of a talking mushroom was too far-out even for Carroll’s rich imagination.

The book depicts a colorful hallucinogenic Amanita muscaria mushroom on which Alice dines (without so much as a parental warning) to become large or small. But while the Cheshire cat is chatty, the mushroom remains mum. [Read more…] about The Secret Language of Mushrooms
