in the works of great masters like Rembrandt.
Ironically The Night Watch, cited in the worm article, long believed to use Orpiment was recently shown to have used pararealgar and semi-amorphous pararealgar instead. But both natural and produced orpiment have been found amongst his pigments in other paintings, like one previous, known as The Jewish Bride. 🧵3/4

The Beginnings of Man -Part 1
The nature of Man has evolved over millions of years, changed by environmental conditions, by the response of his instinctual nature and by the actions of his ego. Man’s inner characteristics are altogether different from the ancestral root which governs other species. Why then is he so different?https://tonyaholisticblog.com/2026/08/31/the-beginnings-of-man-part-1/

#ArtRepostJuly Day 28: Environment
Kinda a stretch but here's a little game project I made. And when I say "I made" I mean pretty much everything; the models, the rigs, the textures, the animations, the sound effects, the code, the environment for the spider to play in...

Busy Beavers - The Turbidity Signature Of Ecosystem Engineers At Work
--
https://doi.org/10.1002/hyp.70661 <-- shared paper
--
H/T @alan Puttock
“Beavers are the quintessential ecosystem engineers. In slow-flowing streams, they create complex wetlands with ponds by building dams and canals that can positively impact biodiversity, hydrology and water quality. These activities can interchangeably capture or release sediment along the watercourse. To date this has not been quantified at the resolution of rainfall events or beaver activity. This study used 15-min frequency, sustained monitoring upstream and downstream of a newly establishing beaver wetland to measure episodic changes in water turbidity at an event resolution. Monitoring showed no significant differences between upstream and downstream turbidity over 160 days when the first pair of beavers, known not to be building dams or canals, were resident. Shortly after introduction of another beaver pair, however, dam building, burrows and canal excavations were quickly observed, resulting in the creation of a complex beaver wetland between 2021 and 2024. Monitoring over 375 days during this period showed significant differences. Downstream turbidity was significantly higher overall than upstream: 13.1 Nephelometric Turbidity Units (NTU) compared to 4.2 NTU. Stochastic spikes in downstream turbidity during the study period not recorded upstream were associated with dam building and burrowing. Overall, there was no significant difference in turbidity loads, which was at least partially explained by a reduction in discharge downstream, particularly in higher flows, during the dam building period. This demonstrates a complex system with the trapping of influent sediment, the storing of water and the periodic release of beaver wetland sediment leading to net balance in loads. These results help provide context for other studies which have used temporally discrete sampling campaigns rather than continuous high-frequency monitoring. They provide a unique insight into the downstream impacts of a rapidly developing beaver wetland over its first three and a half years in a landscape that hasn't had beavers for over 400 years…"

💁🏻♀️ ICYMI: 🐦🌀 If you've ever spotted a shorebird spinning in circles on the water, you might have wondered if it was okay.
Wilson's #phalaropes actually spin to create a small vortex that sucks #invertebrates up to the surface. It's a clever way to forage for food that some say makes them look like "demented wind-up toys."

One of the highlights of my day was when William Harland, a talented ecology undergrad here at #LincolnUniversityNZ, stopped by my office to show me his photos of temnocephalid flatworms. These distinctive squat tentacled flatworms live in colonies on NZ's freshwater crayfish, koura, and eat scraps left over when the koura feed. They apparently cause no bother to the koura.
William found these at Poolburn Reservoir in central Otago.
Amazing!

The “chemization” of aquatic habitats
“Mapping chemical footprints of organic micropollutants in European streams. There is increasing awareness that chemical pollution of freshwater systems with complex mixtures of chemicals from domestic sources, agriculture and industry may cause a substantial chemical footprint on water organisms, pushing aquatic ecosystems outside the safe operating space.” >>

Everything comes to an end eventually. I've run out of good hermit photos, so I'm pausing the Daily Hermit posts for now. (Just in time for Arachtober.) Here's a GrainyHand, deciding whether it's safe to come out of the shell. He's halfway there; GrainyHands, feeling threatened, retreat deep inside, out of sight. #VancouverIsland #HermitCrabs #IntertidalInvertebrates #Invertebrates #MarineLife #DailyHermit
-
Say ah! A "tonsil" level view of a Grainy Hand hermit. (Who has no tonsils, but you get the idea.) 3 sets of maxillipeds, clearly visible; behind these are the small chewing and sorting appendages, the maxillae and maxillules, and at the back the strong, crushing jaws, or mandibles. #VancouverIsland #HermitCrabs #IntertidalInvertebrates #Invertebrates #MarineLife #DailyHermit
-
Textures; knobs and sawteeth and hairs... A Grainy Hand hermit in the sunlight. An old friend; I named him "Big Blue". #VancouverIsland #HermitCrabs #IntertidalInvertebrates #Invertebrates #MarineLife #DailyHermit
-
Deceptive; it looks like an eye like ours; it's not. Hermits have compound eyes, with thousands of ommatidia, each with its own lens. Wild guess: does the black spot in the centre work as camouflage, an imitation of the lens of a vertebrate's eye? #VancouverIsland #HermitCrabs #IntertidalInvertebrates #Invertebrates #MarineLife #DailyHermit
-
Hi, there! Hermits in a tank like to sit right up against the glass, watching the big world outside. Sometimes I wonder what they think of us and our frantic dashing about. #VancouverIsland #HermitCrabs #IntertidalInvertebrates #Invertebrates #MarineLife #DailyHermit
-
Another freshly molted hermit, waiting while her skin stretches and hardens, safely hidden high in the sea lettuce. Here in the tank there are few predators; no fish, no gulls, no octopuses. But there's always a crab or two down on the sand. Vicious little beasts, says Hermie, always ready for a snack of soft hermit abdomen! #VancouverIsland #HermitCrabs #IntertidalInvertebrates #Invertebrates #MarineLife #DailyHermit
-
The everlasting search for new togs. It's not only after a molt that a hermit decides to switch shells. You never know; this one might be more roomy, lighter, more comfortable; better check it out! #VancouverIsland #HermitCrabs #IntertidalInvertebrates #Invertebrates #MarineLife #DailyHermit
-
Midnight activity; a Holm's hermit on a feeding barnacle. With a pregnant copepod and something unidentfiable; white tentacles with fuzzy tops. Many marine critters are more active at night. #VancouverIsland #HermitCrabs #IntertidalInvertebrates #Invertebrates #MarineLife #DailyHermit

Tending to the brood. Video of a Hairy hermit crab with her eggs. #HermitCrabs #DailyHermit #Invertebrates #IntertidalInvertebrates #Nature https://youtu.be/4xfEJB6vgow?si=1ufqJX_zv3CHrdAH
-
Big responibility. Hairy hermit, in berry, with her hundred or so eggs. She'll tend to them for weeks, moving them in and out of the shell, washing and grooming them, until they hatch and float away. #VancouverIsland #HermitCrabs #IntertidalInvertebrates #Invertebrates #MarineLife #DailyHermit
-
"Furry". Like Grandad, this hermit wears a coat of epibionts, but he's younger and more recently colonized; hydroids cover both the hermit and his shell. He clutches his mate; she's fuzz-free. As are his eyes. #VancouverIsland #HermitCrabs #IntertidalInvertebrates #Invertebrates #MarineLife #DailyHermit
-
Barnacle, hermit, barnacles. This hermit's a Hairy, serving both as barnacle transport and barnacle clean-up crew. Essential services.#VancouverIsland #HermitCrabs #IntertidalInvertebrates #Invertebrates #MarineLife #DailyHermit #Invertefest
-
In this together. Accidental triple exposure. Focusing through folded pages of a book, the camera caught the switch between screen saver photos. Hermit, tree, sky, marine life encyclopedia, tech; we sink or swim together. #VancouverIsland #HermitCrabs #IntertidalInvertebrates #Invertebrates #MarineLife #DailyHermit #Invertefest #AccidentalPhotography
-
Holms' hermit, on the job. When a barnacle dies, hermits quickly clean it out, removing the interior plates, scrubbing the walls, leaving the place ready for occupancy by other critters: anemones, worms, even fishes. #VancouverIsland #HermitCrabs #IntertidalInvertebrates #Invertebrates #MarineLife #DailyHermit #Invertefest
-
Living in a cave? Or is that a hungry fish? I keep coming back to this pic and wondering. What was she thinking? That shell is far too big for her! Or maybe not; she flips it over and walks away with it. She's stronger than she looks. #VancouverIsland #HermitCrabs #IntertidalInvertebrates #Invertebrates #MarineLife #DailyHermit #Invertefest
-
Black-eyed hermit, making a mess. He's in a tidy tank in a local aquarium; so neat and clean he is, but look at the snowstorm under his shell; he's stirring up the sand in search of edibles. #VancouverIsland #HermitCrabs #IntertidalInvertebrates #Invertebrates #MarineLife #DailyHermit #Invertefest
-
Block party. A half-dozen hermits spending the afternoon together; the ones on top get a good view, but everyone benefits: comfort, companionship, shared information, safety. Maybe more; they would know. #VancouverIsland #HermitCrabs #IntertidalInvertebrates #Invertebrates #MarineLife #DailyHermit
-
"How's it going, buddy?" Hermits are social critters. They spend hours just hanging out with their friends, preferably on some high spot where they can watch the world go by. Two Grainy-Hands meet on a clamshell lookout. #VancouverIsland #HermitCrabs #IntertidalInvertebrates #Invertebrates #MarineLife #DailyHermit
-
Homebody. This tiny hermit lives in a tubeworm's empty tube rather than in a snail shell. She never leaves the tube; her mate visits her wearing a piece of broken tube. An uncoiled abdomen fits in tidily. #VancouverIsland #HermitCrabs #IntertidalInvertebrates #Invertebrates #MarineLife #DailyHermit
-
Quality time. A Hairy hermit couple hangs out cosily together, sitting in the sunlight, letting time pass. He holds her by the rim of her shell; she rests quietly, taps his cheliped when it's time for action. #VancouverIsland #HermitCrabs #IntertidalInvertebrates #Invertebrates #MarineLife #DailyHermit
-
Living dangerously. A miniature hermit balances on the tip of the leg of a small shore crab. She's tiny, but valiant. In the second photo, an even tinier hermit walks along a crab's cheliped, ignoring the watchful eye above. It's a big world out there; so many adventures ahead! #VancouverIsland #HermitCrabs #IntertidalInvertebrates #Invertebrates #MarineLife #DailyHermit
-
New outfit, with all the trimmings. Minutes ago, this hermit backed out of the old exoskeleton, leaving behind hairs and eyes and antennae and all. But here he is with everything intact, all prepared under cover of the old skin. #VancouverIsland #HermitCrabs #IntertidalInvertebrates #Invertebrates #MarineLife #DailyHermit
-
Old clothes. A growing hermit backs out of the old, too small exoskeleton. Everything goes: the whole cephalothorax, legs and chelipeds, eyes and antennae, tiny hairs. The new skin is soft, stretchy. For a short while. #VancouverIsland #HermitCrabs #IntertidalInvertebrates #Invertebrates #MarineLife #DailyHermit
-
Secret shelter. I picked up an old clamshell, heavy with barnacles, and looked inside. Find the hermit! At low tide, hidden space is highly prized; 3 hermits share the space with assorted snails and worms. #VancouverIsland #HermitCrabs #IntertidalInvertebrates #Invertebrates #MarineLife #DailyHermit
