“I like it when a flower or a little tuft of grass grows through a crack in the concrete. It’s so f#@kin’ heroic.”*…

From dilapidated power plants, abandoned medical facilities, and amusement parks left in rusted ruin, the compelling scenes that French photographer Jonathan Jimenez, aka Jonk (previously), captures are evidence of nature’s endurance and power to reclaim spaces transformed by people. Now compiled in a new book titled Naturalia II, 221 images shot across 17 countries frame the thriving vegetation that crawls across chipped concrete and architecture in unruly masses.

This succeeding volume is a follow-up to Jonk’s first book by the same name and focuses on the ways the ecological crisis has evolved during the last three years. He explains the impetus for the book in a statement:

On the one hand, the situation has deteriorated even further with yet another species becoming extinct every single day. Global warming continues and has caused repeated natural catastrophes: floods, fires, droughts, etc. On the other hand, our collective awareness has widely increased. We are still a long way from the commitment needed to really change things, but we are heading in the right direction. Millions of initiatives have already emerged, and I hope that my photos and the message contained within them can play a small part in the collective challenge facing us all…

On an apposite note: “Forest the size of France regrown worldwide over 20 years, study finds.”

As we inspect the inexorable, we might spare a thought for Hugo Marie de Vries; he died on this date in 1935. A botanist, he introduced the experimental study of organic evolution– and was, thus, was one of the first geneticists. His rediscovery in 1900 (simultaneously with the botanists Carl Correns and Erich Tschermak von Seysenegg) of Gregor Mendel’s principles of heredity and his theory of biological mutation, though considerably different from a modern understanding of the phenomenon, resolved ambiguous concepts concerning the nature of variation of species that, until then, had precluded the universal acceptance and active investigation of Charles Darwin’s system of organic evolution.

He suggested the concept of genes and introduced the term “mutation”, and developed a mutation theory of evolution.

Crown shyness

 

In certain forests, when you look up you will see a network of cracks formed by gaps between the outermost edges of the tree branches. It looks like a precisely engineered jigsaw puzzle, each branch growing just perfectly so it almost—but not quite—touches the neighboring tree. This beautiful phenomenon is called crown shyness.

Crown shyness doesn’t happen all the time, and scientists aren’t completely certain why it happens at all…

The forest keeps its secrets… Despite decades of study– and a profusion of postulation– no one yet fully understands “The Mysteries of Crown Shyness.”

As we keep to ourselves, we might spare a thought for Gregor Johann Mendel; he died on this date in 1884. After a profoundly-unpromising start, Mendel became a scientist, Augustinian friar, and abbot of St. Thomas’ Abbey in Brno, Moravia (today’s Czech Republic).  A botanist and plant experimenter, he was the first to lay the mathematical foundation of the science of genetics (of which he is now consider the “Father”).  Over the period 1856-63, Mendel grew and analyzed over 28,000 pea plants.  He carefully studied the height, pod shape, pod color, flower position, seed color, seed shape and flower color of each– and from those observations derived two very important generalizations, known today as the Laws of Heredity.

Feeling blue?…

Your correspondent recently received an email from a genealogically-inclined first cousin concerning a possible common ancestor, one Martin Fugate, who, it appears, may be our great-great-great-great-great-grandfather.  Grandpa Martin was an orphan, an immigrant from France to Kentucky in the late 18th Century– unremarkable for the time in any way, but one: he seems to have introduced into his bloodline a rare condition called “methemoglobinemia“… that’s to say, for generations to come many offspring were (and are) born with blue skin coloring…

Benjamin “Benjy” Stacy so frightened maternity doctors with the color of his skin — “as Blue as Lake Louise” — that he was rushed just hours after his birth in 1975 to University of Kentucky Medical Center.

As a transfusion was being readied, the baby’s grandmother suggested to doctors that he looked like the “blue Fugates of Troublesome Creek.” Relatives described the boy’s great-grandmother Luna Fugate as “blue all over,” and “the bluest woman I ever saw.”

In an unusual story that involves both genetics and geography, an entire family from isolated Appalachia was tinged blue. Their ancestral line began six generations earlier with a French orphan, Martin Fugate, who settled in Eastern Kentucky.

Doctors don’t see much of the rare blood disorder today, because mountain people have dispersed and the family gene pool is much more diverse. But the Fugates’ story still offers a window into a medical mystery that was solved through modern genetics and the sleuth-like energy of Dr. Madison Cawein III, a hematologist at the University of Kentucky’s Lexington Medical Clinic…

As we remind ourselves that in-breeding isn’t restricted to the South, we might recall that it was on this date in 1828 that John Adams II, son of then-President John Quincey Adams, married his first cousin, Mary Catherine Hellen, in a White House ceremony.  John II’s grandfather, President John Adams, had married his third cousin, Abigail Smith.  Intermarriage skipped a generation with John Quincy Adams, who married a non-relative.

Then, in 1853, John II’s and Mary’s daughter, Mary Louisa Adams, also married a family member–her second cousin, William Clarkson Johnson, the son of her first cousin, Abigail Louisa Smith Adams– President John Adams’ great-grandson… notable for two reasons: both bride and groom were descended from President John Adams, and at the same time, it was the first marriage between descendants of two different presidents.
