Being a mother has its challenges, particularly when your young have a habit of eating their siblings. But black widow spiders desperate to keep some house order may stop their offspring from indulging in cannibalism by putting them on an even playing field.
Without maternal intervention, “the offspring might turn on each other and start eating each other, because that’s what spiders do,” says Chadwick Johnson, a biology professor at Arizona State University and the lead author of a recent study on black widows published in Animal Behavior.
VANCOUVER — Think Miley Cyrus, but with a few more legs.
Black widow spiders use jittery, abdominal movements not unlike twerking — the hip-shaking dance move made infamous by Cyrus — to navigate the dangerous world of arachnid mating, according to a newly published study from a team of British Columbia researchers.
Specifically, the vibrations from a “twerking” male black widow tell a female perched on her web that she’s being approached by a potential mate, rather than dinner.
OKLAHOMA CITY — Authorities are responding to wildfires in Oklahoma and Kansas that have led to evacuations, scorched mostly rural land and destroyed an unknown number of structures.
In Oklahoma, the largest fire was in the same area near the border with Kansas where blazes last month scorched hundreds of square kilometres.
Authorities there urged the approximately 300 residents of Freedom, about 270 kilometres northwest of Oklahoma City, to evacuate their homes on Tuesday afternoon, Woods County Emergency Management Director Steve Foster said.
