Study shows how birds, bats and lizards play their roles in preserving plant species in face of global climate change Add insect-feeding birds, bats and lizards to the front lines of the battle against global climate change. Summarizing the results of more than 100 experiments conducted on four continents, UC Irvine ecologist Kailen A. Mooney and colleagues found that these insect-gobbling animals increase plant growth by reducing the abundance of plant-feeding insects and the damage they do...

New evidence that specialized adaptations are not evolutionary dead ends Blind scorpions that live in the stygian depths of caves are throwing light on a long-held assumption that specialized adaptations are irreversible evolutionary dead-ends. According to a new phylogenetic analysis of the family Typhlochactidae, scorpions currently living closer to the surface (under stones and in leaf litter) evolved independently on more than one occasion from ancestors adapted to life further below the...

Like silkworm moths, butterflies and spiders, caddisfly larvae spin silk, but they do so underwater instead on dry land. Now, University of Utah researchers have discovered why the fly's silk is sticky when wet and how that may make it valuable as an adhesive tape during surgery. "Silk from caddisfly larvae "“ known to western fly fishermen as 'rock rollers' "“ may be useful some day as a medical bioadhesive for sticking to wet tissues," says Russell Stewart, an associate...

Just because cricket moms abandon their eggs before they hatch doesn't mean they don't pass wisdom along to their babies. New research in the American Naturalist shows that crickets can warn their unborn babies about potential predator threats. Researchers Jonathan Storm of the University of South Carolina Upstate in Spartanburg and Steven Lima of Indiana State University placed pregnant crickets into enclosures containing a wolf spider. The spiders' fangs were covered with wax so the spiders...

Scorpion venom is notoriously poisonous "” but it might be used as an alternative to dangerous and addictive painkillers like morphine, a Tel Aviv University researcher claims. Prof. Michael Gurevitz of Tel Aviv University's Department of Plant Sciences is investigating new ways for developing a novel painkiller based on natural compounds found in the venom of scorpions. These compounds have gone through millions of years of evolution and some show high efficacy and specificity for...

A spider may be the reason fog-catching nets, which provide precious water in rain-starved parts of the world, may be ready for a high-tech upgrade. Chinese scientists reported their research in the journal Nature on why spider's silk is not only famous for strength but also terrific for collecting water from the air, sparing the creature the hunt for a drink. The secret lies in the silk's tail-shaped protein fibers that change structure in response to water. The tiny section of thread...

The new species is the largest of its type in the Middle East, but its habitat is endangered A new and previously unknown species of spider has been discovered in the dune of the Sands of Samar in the southern Arava region by a team of scientists from the Department of Biology in the University of Haifa-Oranim. Unfortunately, however, its habitat is endangered. "The discovery of this new spider illustrates our obligation to preserve the dune," says Dr. Shanas, who headed the team of...

With would-be goblins and ghosts set to drape those huge fake spider webs over doorways and trees for Halloween, scientists in Wyoming are reporting on a long-standing mystery about real spider webs: It is the secret of spider web glue. The findings are an advance toward a new generation of biobased adhesives and glues "” "green" glues that replace existing petroleum-based products for a range of uses. A report on the study was published in ACS' Biomacromolecules, a monthly journal....

Scientists have confirmed that spider webs discovered in Britain are the oldest on record, dating back 140 million years to the Cretaceous period. The webs, which were enclosed in amber, were discovered on a beach in East Sussex by fossil hunter Jamie Hiscocks and his brother Jonathan. Professor Martin Brasier, a paleobiologist at the Oxford University, said the fossils were the earliest spider webs ever to be entered into the fossil record. "This amber is very rare. It comes from the very...

2014-04-07 13:05:31

The Cellar Spider (Pholcus phalangioides), known also as the Skull Spider because of its cephalothorax resembling a human skull, is a spider belonging to the family Pholcidae. The females have a body length of about 9 millimeters; the males are slightly smaller. The legs are about 5 to 6 times the length of the body. Its habit of living on the ceilings of room, garages, caves, or cellars gives rise to one of its common names. They are thought to be beneficial in some parts of the world...

Crossopriza lyoni is a widespread species of cellar spiders that prefer to live in or around human structures. They are commonly known as Tailed Cellar Spiders, Tailed Daddy Longlegs Spiders, and occasionally Box Spiders. They all possess exceptionally long and fragile legs that can reach up to 2.4 inches long and a body length of that ranges from .098 to .28 inches. Their abdomens are distinctly square shaped when they are viewed from the side and their carapace is more or less circular...

The Spruce Fir Moss Spider (Microhexura montivaga) is an endangered species of spider that can be found at high elevations in the southern Appalachian Mountains. Initially identified in 1923, they inhabit moss that grows on rocks under the forest canopy. It is one of the smallest mygalomorph spiders, with the adults only measuring 3 to 4 millimeters. The coloration varies from light brown to yellow-brown to a darker reddish brown color, with no markings on its abdomen. Their chelicerae...

Arachnology
2012-10-15 15:14:24

Arachnology is the scientific study of spiders and related specimens: including scorpions, pseudo-scorpions and harvestmen. These animals are collectively known as arachnids. Ticks and mites, on the other hand, although are in the arachnid family, do not typically fall under archeology studies; these small creatures are usually studied under Acarology. Arachnology derives from the Greek words arachne (meaning spider), and logia (meaning sayings). People who study spiders and other...
