Newly discovered marsupial the victim of fatal attraction: Due to stress hormone, males die before young are born

A QUT mammalogist has discovered a highly sexed mouse-like marsupial in Queensland’s Springbrook National Park. The Black-tailed Antechinus was found in the high-altitude regions of the World Heritage Area. It’s the third new species in the genus Antechinus Dr Andrew Baker’s research team has discovered in the past two years, all from south-east Queensland.Dr Baker said he suspected the rare, Black-tailed Antechinus was a separate species when he and his team came across it last May because it had distinctive yellow-orange markings around its eyes and on its rump, and a black tail and feet.”Comparing it to the Dusky Antechinus, which inhabits south-east Australia, we thought it was probably new,” said Dr Baker, from QUT’s Science and Engineering Faculty.”We laid about 300 traps baited with peanut butter and oats. When we caught the first black-tailed antechinus in a trap, we knew we were onto something pretty special.”Dr Baker is now applying for an endangered species listing.”Antechinus males and females are highly promiscuous; males mate for long periods of time with many females to promote their own genes,” Dr Baker said.”A single female’s brood of young will typically be sired by several fathers. But during mating, stress hormone levels rise dramatically, eventually causing the males’ bodies to shut down. The males all die before their young are born.”The results of the team’s studies have been published in the journal Zootaxa.The Black-footed Antechinus is a coup for Dr Baker and his research partners from the Queensland Museum and Queensland Parks and Wildlife Service.New mammal discoveries are rare, with only a handful typically discovered in the world each year.Dr Baker said the Black-tailed Antechinus likely won’t be the last unique creature to be unearthed in Springbrook National Park.”The Gondwanaland rainforest relic at Springbrook is special and unique,” he told the Gold Coast Bulletin. “It would not surprise me if there are other animals that are new in that area. Such things are about place not species.”Story Source:The above story is based on materials provided by Queensland University of Technology. Note: Materials may be edited for content and length.

Does more stress equal more headaches?

http://feeds.feedburner.com/~r/sciencedaily/living_well/~4/Rcj8QVtAG2k

A new study provides evidence for what many people who experience headache have long suspected — having more stress in your life leads to more headaches. The study released today will be presented at the American Academy of Neurology’s 66th Annual Meeting in Philadelphia, April 26 to May 3, 2014.For the study, 5,159 people age 21 to 71 in the general population were surveyed about their stress levels and headaches four times a year for two years. Participants stated how many headaches they had per month and rated their stress level on a scale of zero to 100.A total of 31 percent of the participants had tension-type headache, 14 percent had migraine, 11 percent had migraine combined with tension-type headache and for 17 percent the headache type was not classified. Those with tension-type headache rated their stress at an average of 52 out of 100. For migraine, it was 62 out of 100 and 59 for those with migraine and tension-type headache.For each type of headache, an increase in stress was associated with an increase in the number of headaches per month. For those with tension headache, an increase of 10 points on the stress scale was associated with a 6.3-percent increase in the number of headache days per month. For migraine, the number of headache days per month went up by 4.3 percent, and 4 percent for those with migraine and tension headache. The results were adjusted to account for factors that could affect the number of headaches, such as drinking, smoking and frequent use of headache drugs.”These results show that this is a problem for everyone who suffers from headaches and emphasize the importance of stress management approaches for people with migraine and those who treat them,” said study author Sara H. Schramm, MD, of University Hospital of University Duisburg-Essen in Germany. “The results add weight to the concept that stress can be a factor contributing to the onset of headache disorders, that it accelerates the progression to chronic headache, exacerbates headache episodes, and that the headache experience itself can serve as a stressor.”The study was supported by the German Federal Ministry of Education and Research.Story Source:The above story is based on materials provided by American Academy of Neurology (AAN). …
