Imagine the
female wolf spider, for example (shown carrying her young in a cluster on her abdomen), ten times her normal size.
They started with arthropods, measuring mercury concentrations
in wolf spiders, camel crickets and pill bugs.
«It's very quiet, but it's what you would hear if you were in the room with a courting spider,» says George Uetz of the University of Cincinnati in Ohio, who discovered the
purring wolf spider with colleague Alexander Sweger.
The Spider Nurse — a crashed alien spaceship has one survivor — a medic in the form of large
wolf spider with a brassy personality.
Jonathan Storm, a behavioural ecologist now at the University of South Carolina Upstate, in Spartanburg, briefly exposed lab - grown female crickets to
wolf spiders whose fangs had been immobilised with wax, then studied the behaviour of their subsequent offspring.
In a later study comparing almost 3400 active genes in 70 spider species, Bond's team found that mostly webless, ground - dwelling arachnids such
as wolf spiders and jumping spiders diversified much more quickly than web weavers, perhaps because they were able to exploit a plethora of new opportunities once they no longer had to build and tend webs.
TO ATTRACT a mate,
male wolf spiders wave their front legs in a display that, unfortunately for them, also attracts the attention of predators.
NICOTINE DEFENSE Tobacco hornworm caterpillars use some of the nicotine in their food to produce a smoker's breath strong enough to drive away
predatory wolf spiders.
The caterpillars breathe out nicotine from the tobacco with every exhale, and their toxic breath
sends wolf spiders fleeing.
Previous work
on wolf spiders has indicated that male courtship vibrations vary when male diet is manipulated during development [41]--[43].
In addition to the work - hungry collectors crawling through NADA New York during its opening Wednesday afternoon, there was another, slightly more venomous crew crawling around: hairy, six -
legged wolf spiders.
Uetz, G. W., Roberts, J. A. & Taylor, P. W. Multimodal communication and mate choice
in wolf spiders: female response to multimodal versus unimodal signals.
Eileen Hebets of Cornell University introduced 81 sexually immature
female wolf spiders to a variety of sexually mature males in the laboratory.
In South American deserts,
the wolf spider Allocosa senex lacks such a sophisticated basket, but still carries sand out of the tunnel using its pedipalps.
Lacking these bristles,
the wolf spider instead glues sand particles together by connecting the grains with fine silk threads.
Menda has since found evidence of hearing in five different spider species: jumping spiders, fishing spiders,
wolf spiders, netcasting spiders and house spiders.
Among spiders,
the wolf spider, Schizocosa uetzi, is unique because males can take on a variety of different looks, or phenotypes.
The researchers found mercury in all the arthropods, but the highest levels were in
the wolf spiders, the team reported in the April Bulletin of Environmental Contamination and Toxicology.
Wolf spiders are carnivorous, and they appeared to be acquiring more mercury through bioaccumulation.
The third group, the Araneomorphae, includes 5500 jumping spiders, 4500 dwarf spiders, 2400
wolf spiders, and thousands of web spinners.
That's why some of the entrants in recent humanoid robot Grand Challenges have looked less human and more like a cross between an orang - utan and
a wolf spider.
Group leader Brett Kennedy describes RoboSimian as a cross between an orang - utan and
a wolf spider — far less humanoid than Atlas.
But for the purring
wolf spider, it's music.
Male «purring»
wolf spiders are virtuosos when it comes to leaf tapping — making sounds that travels through air to another leaf where a female picks it up
Preliminary data suggest that during the foggy season,
wolf spiders in the area see their mercury levels multiply by five.
Field experiments with glycosidase - silenced caterpillars revealed that
the wolf spider Camptocosa parallela, a predator of tobacco hornworm larvae, captured and killed about the same number of glucosidase - silenced larvae and controls, but ingested significantly fewer glucosidase - silenced larvae.
It was
a wolf spider, a species that tended to hide during the day and hunt for prey at night.
We had
wolf spiders (HUGE ones) when we moved in our house 3 yrs ago.
Wolf spiders would have free run around here but I never see them anymore.
