There is a Good Whip Spider Boom. What Gives?

Amblypygids became his version of Colla’s caves. Hard to find at first. Instead of what he has done, however, he has become the most important provider of Harvey’s spreadsheets, describing new species anywhere from Timor-Leste to Belize. Looking at his oeuvre, it might seem like there’s an endless army moving around, but that’s not it. Often, de Miranda said, “people just lack attention.”

Colla used to be however, looking – not for amblypygids specifically, but for what the Italian bunker was like in 2003. He wasn’t the only one. Trieste sits near the tip of the Italian boot, between the Slovenian border and the Adriatic Sea. To the east is a plain full of galleries and grottoes that Colla called the birthplace of cave science. The claim may be controversial, but the region’s long-standing interest in caves is not: Between 1880 and 1920, about 2,000 local caves were described, and members of the Trieste Alpine Club explored everything from mushrooms to caves in historic sites since 1945. many people have been coming to the natural tunnels outside the town-and the people below-it seems unlikely that amblypygids have not ‘y namatikdan.

The world of whipping research is small, and de Miranda joined Colla’s study shortly after the club discovered the first amblypygid. This is not a new breed. In fact, it’s widespread, a denizen of Jerusalem’s sewers and caves in Turkey-a class he recently helped document for the first time in Jordan, where it was expected, and in mainland Greece, where it didn’t. . Amblypygids are tropical and subtropical, and Jordan has the right climate, the kind of place that no one has bothered to record the species until recently, but where the bug is believed. However, Athens is much chillier, and de Miranda isn’t sure if the population there is indigenous or introduced. But Trieste is more than 1,000 miles northwest. Hebets, who was not involved in the project, heard rumors of unreported amblypygids in Italy. Despite de Miranda, this particular region seems impossibly cold.

The bunker known as Kleine Berlin-Little Berlin-is a complex of four different residences, three built for Italian civilians, one for German soldiers. Inside, Colla sees the ground reclaiming part of the past, wartime graffiti in some areas, stalactites in others, here’s a toilet, there’s the like of overgrown minerals on the walls and floor. . Whip spiders were spotted on the Nazi side, in a wet, 260-foot-long tunnel near the courthouse, covered in rust stains and unrestricted by tourists. There they were, clinging to the wall: Not just an amblypygid, but an entire population. He and his companions count to nine in total. Later, green children appeared behind an adult, the little antenna-legs crossed, de Miranda said, “like a soup of noodles.”

But as far as researchers know, the entire population of Trieste is women. That means they may have given birth without any males, using a strategy called parthenogenesis – Greek for “virgin birth. This is a deception seen in certain arachnids, insects, crustaceans, and even reptiles, which lay live eggs without sexual intercourse. Many-including amblypygids, it seems-are versatile, sometimes mating, sometimes making babies solo.

The reason for going one way or the other may be nature. “It can be a factor of size, where you reach an age -‘ I haven’t met any similar varieties of mine, I’m just going to start making eggs, ’” explains Mercedes Burns, a arachnologist at the University of Maryland, Baltimore County.How it works in amblypygids is still unclear, but in other creatures, the chromosomes in the egg duplicate themselves or the egg undergoes a kind of faux-fertilization.Some of cells involved in egg development also have chromosomes, and instead of messing up as usual, they can act a bit like sperm, providing the missing piece so the offspring have all the genetic material needed. Usually, the maneuver is risky-a bad curveball and the entire population can bust-but it’s easy to use for stowaways: A woman can go anywhere and find her cock. grind pole clones.
