Dancing peacock spiders turned an arachnophobe into an arachnologist
Not yet a college graduate, Joseph Schubert has described 12 of 86 known peacock spider species
Joseph Schubert spends hours at a time lying in the dirt of the Australian outback watching for tiny flickers in the sparse, ground-hugging foliage. The 22-year-old arachnologist is searching for flea-sized peacock spiders, and he admits, he’s a little obsessed.
But it wasn’t always so. Schubert grew up fearing spiders, with parents who were “absolutely terrified” of the eight-legged crawlers. “I was taught that every single spider in the house was going to kill me, and we should squish it and get rid of it,” he says.
Then Schubert stumbled across some photographs of Australia’s endemic peacock spiders, a group named for the adult males’ vivid coloring and flamboyant dance moves aimed at wooing a mate (SN: 9/9/16; SN: 12/8/15). And he was hooked.
“They raise their third pair of legs and dance around and show off like they are the most amazing animals on the planet, which in my eyes they are.” He decided to pursue a career in arachnology. And despite not quite having completed his undergraduate degree in biology, he’s begun working part-time at Museums Victoria in Melbourne, and has already made a mark.
Of the 86 known peacock spider species — each just 2.5 to 6 millimeters in length — 12 have been described by Schubert, including seven named in the March 27 Zootaxa. Those seven were found at a range of sites across Australia, including the barren dunes and shrublands of Victoria state’s Little Desert and the red rocks and arid outback gorges of Kalbarri National Park, north of Perth.
“It’s a fantastic feeling to be able to document these species and empower them with names” that offer scientific recognition as well as a chance for legislated protections if needed, Schubert says. “I am very lucky to work in this field. I get to pull out my microscope and observe things that nobody has ever documented before.”
Sometimes, Schubert finds a peacock spider by looking for draglines of silk glimmering in the sunlight. As these tiny spiders from the genus Maratus leap from leaf to leaf in search of insect prey, they extend these safety lines behind them to catch them in case they fall.
If he’s really lucky, Schubert will catch a male spider mid-boogie, lifting its iridescent abdomen and vigorously waggling its legs in the air as it jerks back and forth in an arachnid tribute to the moonwalk. That usually happens during the Australian springtime in about September and October, as the males become sexually mature towards the end of their lives and take on brightly colored forms.
Those wild colors inspired some interesting names. Schubert’s dubbed one bright blue species with yellow spots Maratus constellatus, because it reminded him of Vincent Van Gogh’s painting The Starry Night. And last year, he called a striking black-and-white jumping spider that is a relative of peacock spiders Jotus karllagerfeldi for the late fashion icon Karl Lagerfeld.
Schubert admits he’s had a lot of help from many Australian photographers, amateur enthusiasts and citizen scientists who send pictures of these miniature spiders to Schubert or share them on social media. Without that vital help, “just a handful of us scientists would be looking … as opposed to thousands [of enthusiasts] uploading via Facebook,” Schubert says.
He still hasn’t entirely gotten over his arachnophobia, though he’s grateful that peacock spiders, while venomous to their tiny insect prey, are harmless to humans. He’s handled hundreds of the spiders and suspects their mouthparts are too small to puncture human skin, even if they wanted to take a bite.
Less charismatic spiders are sometimes still a challenge for Schubert’s nerves, though. In the Little Desert last year, while putting a 5-centimeter-long wolf spider into a container, the spider pushed the lid aside and crawled up Schubert’s arm. “I screamed,” he says, laughing. “But if I can prepare and mentally tell myself that a spider is not looking to hurt me, and even if it does bite me, it’s not going to do anything, then I can put myself in the mental position to handle it.”
The bushfires that swept vast areas of Australia between September and February (SN: 1/13/20) could potentially have burned through the tiny ranges of several peacock spider species found in Victoria’s alpine regions. Nobody has yet been able to check, and future field work is currently on hold amid the ongoing COVID-19 pandemic.
As soon as Schubert can get out again, he will — whether on a research trip or on his next holiday. The only problem, he says, is that “it’s sometimes difficult to find other people who want to spend personal time looking for spiders.”
Cribellate spiders spin thousands of tiny nanofibers into sticky threads. To keep from getting caught in their own webs, these spiders use a nonstick comb on their back legs. Now, researchers reporting in ACS Applied Nano Materials have patterned an antiadhesive nanostructure inspired by this comb onto a foil surface, creating a handy tool to control sticky lab-made nanomaterials for medical, smart textile and other applications: here.

The Rich Are Having Themselves A Fine Coronavirus
Last week, Federal Reserve Chairman Jerome Powell quietly said something outrageous. Asked whether the biggest banks in the country would continue making cash payments to their shareholders amid the worst economic breakdown in recorded history, Powell said yes.
“That’s a perfectly normal thing in our capitalist system”, he told David Wessell, a former Wall Street Journal reporter turned monetary policy guru at the nonpartisan Brookings Institution.
The world stands at the brink of financial catastrophe. Congress has passed a massive corporate bailout, and Powell himself has initiated the most aggressive financial rescue operation ever contemplated by the American central bank. These things do not happen when the banking system is hunky-dory.
And yet Powell continues to let the biggest banks in the country cut checks to their shareholders ― aka “rich people”, in the parlance of our times ― as a matter of routine. Almost half of all dividend income flows to the top 1% of income-earning households, while less than 8% of households in the bottom 60% earn any dividend income at all. And when the terms of the emergency coronavirus legislation were being debated in Congress last month, nobody lifted a finger to halt this miscarriage of capital ― not Senate Majority Leader Mitch McConnell (Republican-Ky.), not House Speaker Nancy Pelosi (Democratic-Calif.).

Swietenia mahagoni, commonly known as American mahogany, Cuban mahogany, small-leaved mahogany, and West Indian mahogany, is a species of Swietenia native to southern Florida in the United States and islands in the Caribbean including the Bahamas, Cuba, Jamaica, Dominican Republic and Haiti. It is the species from which the original mahogany wood was produced.
Swietenia mahagoni is listed as “Threatened” in the Preservation of Native Flora of Florida Act. It is the national tree of the Dominican Republic.
The earliest recorded use of S. mahagoni was in 1514. This date year was carved into a rough-hewn cross placed in the Catedral de Santa María la Menor in Santo Domingo, the capital of what is now the Dominican Republic, at the beginning of the building’s construction. Completed about 1540, it is the oldest church in the West Indies, and its interior was ornamented with carved mahogany woodwork that is still in almost perfect condition after 500 years in the tropics.
Before the American revolution, botanists from Europe had explored and described the flora of the Carolinas, Florida, and the Bahamas. Fifty-six years before naturalist and illustrator John James Audubon was born, Volume Two of Mark Catesby‘s folio sized natural history was published in 1729. Catesby’s hand-colored plate of the mahogany tree, along with a description in English and French (not Latin as might have been expected), was the basis for Linnaeus using his new binomial nomenclature to name it. When Linnaeus’ description was published in 1758 as Cedrela mahagoni, mahogany had been well known for more than 200 years to the lumber and woodworking trades. Two years later, Nikolaus Joseph von Jacquin reclassified it and placed the West Indies Mahogany Tree into his newly created genus, Swietenia. His classification still stands.
Fifty years after Argentinean revolutionary Ernesto “Che” Guevara visited Sri Lanka, the Mahogany tree that he planted still stands tall. Che visited the Yahala Kele rubber estate in Horana to study rubber planting methods during his brief stay in the country and planted the Mahogany tree on August 7, 1959.

Mahogany tree family dates back to last hurrah of the dinosaurs
April 15, 2020
You might own something made from mahogany like furniture, paneling or a musical instrument.
Mahogany is a commercially important wood, valued for its hardness and beauty. The United States is the world’s top importer of the tropical timber from leading producers like Peru and Brazil. Unfortunately, mahogany is harvested illegally a lot of the time.
For science, mahogany is important, too — the fossil presence of the mahogany family is a telltale of where tropical forests once stood. Until recently, paleobotanists had only found evidence the mahogany family extended back to the Paleocene (about 60 million years ago).
Now, a new paper written by University of Kansas researcher Brian Atkinson in the American Journal of Botany shows the mahogany family goes back millions of years more, to the last hurrah of the dinosaurs, the Cretaceous.
“For understanding when many of the different branches of the tree of life evolved, we’re primarily dependent on the fossil record,” said Atkinson, an assistant professor of ecology & evolutionary biology and curator in the Biodiversity Institute’s Division of Paleobotany. “In this case, Meliaceae, the mahogany family, is an ecologically and economically important group of trees. A lot of researchers have used this group as a study system to better understand the evolution of tropical rainforests. This work is the first definitive evidence that the tropically important trees were around during the Cretaceous period, when we first start to see the modernization of ecosystems and modern groups of plants.”
Atkinson’s new work pushes back the fossil record for Meliaceae by 15 to 20 million years, the Campanian stage of the Late Cretaceous, from between 72-79 million years ago. The well-preserved mahogany specimen Atkinson analyzed was discovered just off Vancouver Island in Canada.
“The rock that contained the specimen was collected by a local fossil collector, Graham Beard, who is the director of the Qualicum Beach Museum of Natural History,” Atkinson said. “He collected it years ago, but I was actually interested in the rock that has this fossil in it for something else. And as I kept preparing this rock, more for the other fossils were in there, this thing showed up by surprise. So, it was kind of found by accident.”
To pinpoint the fossil’s identity, Atkinson carefully studied the structure of the fossilized fruit and also analyzed phylogenetic information to figure out its relationship to other species in the mahogany family.
“I combined the molecular data from living representatives of the mahogany family with the morphology of the fossil, as well as the morphology of living species,” he said. “And then I subjugated that combined dataset to phylogenetic analyses, which allows us to reconstruct evolutionary relationships. Based on this analysis, we found the fossil is closely related to this genus called Melia, which is living today.”
The KU researcher gave the oldest-known mahogany fossil the scientific name Manchestercarpa vancouverensis — the species name signifies where the specimen was discovered, and the genus is named after an esteemed colleague in the field.
“I named it after a prolific paleobotanist who’s really improved our understanding of the evolution of flowering plants through the fossil record,” Atkinson said. “So, I named it in honor of Steve Manchester, who’s at the University of Florida Museum of Natural History.”
While it’s noteworthy that Atkinson has pushed back the origin story of mahogany, he stressed it also helps improve our understanding of the rate of early flowering plant evolution and, in turn, our grasp of larger modern ecosystems.
“They’re our most diverse group of plants on Earth, and so there’s a whole lot to explore,” he said. “And there are some cool things you can do methodologically that you might not be able to do with other groups of plants. I can really ask some exciting paleontological and general evolutionary questions with this group.”

Logging threatening endangered caribou
April 15, 2020
Summary: Researchers found habitat and food web changes from forestry are encouraging more wolf packs to prey on caribou. Researchers attached video and GPS-tracking radio collars to caribou and wolves to monitor foraging and movements, including signs wolves had killed a caribou. Overs 6 years they collected and compared data from a site with extensive logging and a site untouched by forestry and found caribou in the disturbed site were not self-sustaining.
Cutting down forests means we’re also cutting down woodland caribou, says a pioneering study by University of Guelph ecologists showing that logging in Ontario’s extensive boreal stands threatens populations of the elusive but iconic herbivore.
In what integrative biology professor John Fryxell calls the first comprehensive study looking at the status of endangered woodland caribou across Ontario, the team found habitat and food web changes caused by forestry are encouraging more wolf packs to prey on caribou. Labelling the study a “clarion call” for conservation measures, he said the new paper shows how human activity, particularly logging, is upsetting food webs and habitat involving caribou, wolves and moose.
“It’s death by a million cuts,” said Fryxell. “Woodland caribou are an iconic species in Indigenous culture, integral to our historical development and a cornerstone in the functioning of boreal food webs. I think of the caribou as a canary in the coal mine for the long-term sustainability and quality of the boreal forest to protect other wildlife.”
Published recently in the Journal of Wildlife Management, the study entailed attaching video collars to 30 caribou to monitor their foraging. The researchers also outfitted about 120 caribou and 50 wolves with regular GPS-tracking radio collars to monitor the animals’ movements, including signs that wolves likely had killed a caribou.
Ontario’s woodland caribou number several thousand animals. An officially endangered species, woodland caribou live below the tree line across most of Canada except the Atlantic provinces.
Logging has moved northward in Ontario over recent decades. As cut forests regrow, their mix of new trees and shrubs attracts moose. Higher moose populations in turn attract wolves, placing caribou at risk of being hunted as well.
Those caribou could move farther north, said Fryxell, but perhaps not soon enough to sustain their numbers.
Over six years, the team studied two sites in northern Ontario spanning about 23,000 square kilometres in all.
One site in Nakina, located about 160 kilometres north of Lake Superior, has been logged extensively since 1970. Regenerating forests contain more deciduous trees such as poplar and willow as well as thicker undergrowth.
The Pickle Lake site, dominated by stands of jack pine, is located about a seven-hour drive from Thunder Bay, beyond the northern limit for forestry. That made for a perfect natural experiment for the researchers to compare conditions in both locations.
To see what caribou might be eating, they sampled kinds of plants growing in each site and analyzed the footage collected from the video collars, or “critter cams”. Caribou eat mostly lichen on the ground and growing on trees.
The researchers also analyzed the information collected from the GPS-tracking radio collars on wolves. Multiple pings from a single spot over an extended period “usually means they’re eating something,” said Fryxell.
Team members then visited those sites to verify what prey had been eaten.
The researchers entered their information into computer models that estimate whether a caribou population will produce enough young to sustain itself or not. They found that caribou in the disturbed site were not self-sustaining, unlike healthier populations at Pickle Lake.
Fryxell said the results likely would apply farther north in Ontario and in other parts of Canada where woodland caribou are endangered by resource extraction.
He said forestry companies need to consider the long-term effects of their operations on plants and animals. Companies should practice rotation cutting to prevent clear-cutting and allow forests to regenerate, said Fryxell.
More immediately, resource managers might need to consider … hindering [wolves’] movements by turning old logging roads back into forest.
He said there’s no evidence that either wolves or moose are threatened.
With plans for further development of Northern Ontario communities, Fryxell hopes to see governments, conservationists, Indigenous groups, industry and others work together to address threats to woodland caribou. “We have an opportunity to learn from what was done in the past to manage better in the future.”
