Beetle keeps rivals off scent of food buried for offspring
<p>Some beetles go to great — and disgusting — lengths for their children.</p>
<p>They scout for a dead mouse or bird, dig a hole and bury it, pluck its fur or feathers, roll its flesh into a ball and cover it in goop — all to feed their future offspring.</p><p>Now scientists think that goo might do more than just slow decay. It also appears to hide the scent of the decomposing bounty and boosts another odor that repels competitors.</p><p>“It helps them to hide their resource from others,” said Stephen Trumbo, who studies animal behavior at the University of Connecticut and led the new research, published Thursday in The American Naturalist. “They try to keep everyone away.”</p><p>The beetles — called burying beetles — aren’t the only creatures who try to deceive their competitors or prey with subtle, sneaky tactics. Large blue butterflies, for example, will imitate certain sounds to manipulate ants. Corpse flowers produce rotting odors to attract insect pollinators that feed on decomposing matter.</p><p>The importance of these interactions are being recognized more and more, said Alexandre Figueiredo, a biologist at University of Zurich, who was not involved in the new study.</p><p>Burying beetles and other things that feed on dead animals — including vultures, opossums and maggots — race each other to track down carcasses. Competition is stiff even among burying beetles, which use special antennae to detect the remains from afar.</p><p>Burying beetles are relatively large, about an inch long, and black with orange markings. The gut secretions they spread on a carcass are antibacterial, and slow down decomposition. Trumbo and his colleagues wondered whether they also prevented rivals from picking up the scent.</p><p>To find out, they collected the gases wafting off dead hairless mice preserved by a kind of burying beetle that is found in forests across North America. The researchers then compared the gases to those from untouched carcasses. </p><p>The beetle-prepped ones gave off much less of an onion-smelling compound that usually attracts burying beetles to fresh remains. They also discovered an increase in another gas from decay that’s known to deter other insects that feed on dead animals.</p><p>Next, they dropped off the dead mice in a Connecticut forest. They found the beetle’s rivals were less likely to discover the ones covered in goop.</p><p>“If you can deter other scavengers, even for a little bit of time, it can buy you a lot,” said Daniel Rozen, a biologist at Leiden University in the Netherlands who was not involved in the new study.</p><p>___</p><p>Follow at @MarionRenault on Twitter</p><p>___</p><p>The Associated Press Health and Science Department receives support from the Howard Hughes Medical Institute’s Department of Science Education.

The former ragga star turned lawmaker came second in the presidential election, and has said the process was marred by widespread fraud and violence.He has not left his home since he went out to vote in the election on Thursday, and on Friday said he was under “seige” as soldiers and pllice surrounded his home, preventing anyone from entering or leaving.”Our leader … is effectively under house arrest,” National Unity Platform spokesman Joel Ssenyonyi told a press conference on Sunday, adding no one was being allowed access.”His home is not a detention facility. We are very concerned about the state in which he is in, and his wife.”A Twitter update under Bobi Wine’s account, written by an administrator as Uganda remains under an internet blackout for a fifth day, said the couple had “run out of food supplies”.The party said prominent MP, Francis Zaake, who had been arrested during an attempted visit to Wine’s house on Friday, had been admitted to hospital “badly beaten and brutalised” by security forces.Ugandan officials have said the soldiers and police were there for Wine’s own security.”Complete sham”Wine and his NUP have yet to outline their next steps after dismissing the election as a “complete sham”.”Once again, a minority clique is forcing themselves on the majority of Uganda. That is something that we are going to resist. It is something that we are going to say no to using every avenue provided for within the law,” said Ssenyonyi.Incumbent Yoweri Museveni, 76, has ruled Uganda since seizing control in 1986.His re-election with 58.6 percent of the vote to Wine’s 34.8 percent, came after the most violent election campaign in recent years, with the harassment of the opposition, media and deaths of scores of Wine’s supporters.Wine said there had been ballot-box stuffing, intimidation, and that his party’s agents had been beaten and chased away during the election on Thursday.Panafricanism and democracyMuseveni has said it was the cleanest election in the country’s history.In a televised speech on Saturday evening, he said Ugandans had voted for “love of their country, panafricanism and democracy”.US State Department spokeswoman Morgan Ortagus praised Ugandans on Saturday for voting “despite an environment of intimidation and fear”.She added that the US was “deeply troubled by the many credible reports of security force violence during the pre-election period and election irregularities during the polls”.(with AFP)</p><p><strong><a href=””></a></strong> <a href=””>(Why?)</a></p> Sun, 17 Jan 2021 11:12:12 +0000 Yahoo Movies Canada
