Ecophysiology and ecological limits of symbiotrophic vesicomyid bivalves (Pliocardiinae) in the Southern Ocean

first_imgGeothermal energy provides an important resource in Antarctic marine ecosystems, exemplified by the recent discovery of large-sized chemosymbiotic vesicomyid bivalves (subfamily Pliocardiinae) in the Southern Ocean. These clams, which we identified as Archivesica s.l. puertodeseadoi, have been reported as dead shells in areas previously covered by Larsen A and B ice shelves (eastern Antarctic Peninsula) and as live animals from active hydrothermal sites in the Kemp Caldera (South Sandwich Arc) at depths of 852–1487 m. Before, A. puertodeseadoi was known only from its type locality in the Argentine Sea, so we considerably extend the range of the species. Observations taken by remotely operated vehicle (ROV) footage show that the clams can live buried in sediment, or epilithically on the surface of rocks in diffuse geothermal flow. Experimental respirometry was conducted at surface pressure on individual bivalves acclimated to either their habitat temperature (4 °C) or elevated temperature (10 °C). The range of standard metabolic rates, from 3.13 to 6.59 (MO2, μmol O2 h−1 g−1 dry tissue mass), is similar to rates measured ex situ for other species in this clade, and rates did not differ significantly between temperature groups. Taken together, these data indicate a range of ecophysiological flexibility for A. puertodeseadoi. Although adapted to a specialist mode of life, this bivalve exploits a relatively broad range of habitats in the Southern Ocean: within sulphidic sediments, epilithically in the presence of diffuse sulphidic flow, or in deep methane-enriched seawater trapped under ice.last_img read more

A century of coping with environmental and ecological changes via compensatory biomineralization in mussels

first_imgAccurate biological models are critical to predict biotic responses to climate change and human‐caused disturbances. Current understanding of organismal responses to change stems from studies over relatively short timescales. However, most projections lack long‐term observations incorporating the potential for transgenerational phenotypic plasticity and genetic adaption, the keys to resistance. Here, we describe unexpected temporal compensatory responses in biomineralization as a mechanism for resistance to altered environmental conditions and predation impacts in a calcifying foundation species. We evaluated exceptional archival specimens of the blue mussel Mytilus edulis collected regularly between 1904 and 2016 along 15 km of Belgian coastline, along with records of key environmental descriptors and predators. Contrary to global‐scale predictions, shell production increased over the last century, highlighting a protective capacity of mussels for qualitative and quantitative trade‐offs in biomineralization as compensatory responses to altered environments. We also demonstrated the role of changes in predator communities in stimulating unanticipated biological trends that run contrary to experimental predictive models under future climate scenarios. Analysis of archival records has a key role for anticipating emergent impacts of climate change.last_img read more

Can Antarctica’s shallow zoobenthos ‘bounce back’ from iceberg scouring impacts driven by climate change?

first_imgAll coastal systems experience disturbances and many across the planet are under unprecedented threat from an intensification of a variety of stressors. The West Antarctic Peninsula is a hotspot of physical climate change and has experienced a dramatic loss of sea‐ice and glaciers in recent years. Among other things, sea‐ice immobilizes icebergs, reducing collisions between icebergs and the seabed, thus decreasing ice‐scouring. Ice disturbance drives patchiness in successional stages across seabed assemblages in Antarctica’s shallows, making this an ideal system to understand the ecosystem resilience to increasing disturbance with climate change. We monitored a shallow benthic ecosystem before, during and after a 3‐year pulse of catastrophic ice‐scouring events and show that such systems can return, or bounce back, to previous states within 10 years. Our long‐term data series show that recovery can happen more rapidly than expected, when disturbances abate, even in highly sensitive cold, polar environments.last_img read more

Naomi Osaka wears Breonna Taylor face mask to honor victims of police shootings at US Open

first_img FacebookTwitterLinkedInEmailUSTABY: KATIE KINDELAN, ABC News(NEW YORK) — Tennis star Naomi Osaka donned a face mask with the name of Breonna Taylor, the 26-year-old Black woman who was shot and killed by Louisville police officers in March, at her debut match Monday night at the U.S. Open.Osaka, the 2018 U.S. Open champion, wore the mask before and after her first-round victory against Japan’s Misaki Doi at Arthur Ashe stadium.Osaka said she brought seven different face masks with her to the Grand Slam tournament, each honoring a different person killed by police.“It’s quite sad that seven masks isn’t enough for the amount of names, so hopefully I’ll get to the finals so you can see all of them,” said Osaka, according to The Associated Press. “I’m aware that tennis is watched all over the world, and maybe there is someone that doesn’t know Breonna Taylor’s story. Maybe they’ll, like, Google it or something.”“For me, [it’s about] just spreading awareness,” she said. “I feel like the more people know the story, then the more interesting or interested they’ll become in it.”Osaka, 22, joined fellow athletes in protest last month after the police shooting of Jacob Blake, a 29-year-old Black man who was shot seven times by police in front of his children. The shooting sparked civil unrest in Blake’s hometown of Kenosha, Wisconsin, and across the country.Osaka protested the shooting by not competing in an Aug. 27 scheduled semifinal match at the 2020 Western & Southern Open.“Hello, as many of you are aware I was scheduled to play my semifinals match tomorrow,” Osaka wrote in a statement shared on Twitter. “However, before I am an athlete, I am a black woman. And as a black woman I feel as though there are much more important matters at hand that need immediate attention, rather than watching me play tennis.”“I don’t expect anything drastic to happen with me not playing, but if I can get a conversation started in a majority white sport I consider that a step in the right direction,” she continued. “Watching the continued genocide of Black people at the hand of the police is honestly making me sick to my stomach.”pic.twitter.com/miKzgSdGxY— NaomiOsaka大坂なおみ (@naomiosaka) August 27, 2020Osaka added in her statement that she is “exhausted of having a new hashtag pop up every few days and I’m extremely tired of having this same conversation over and over again.”“When will it ever be enough?” she asked, ending her statement with Jacob Blake’s name, Breonna Taylor’s name, Elijah McClain’s name and George Floyd’s name.Taylor was fatally shot in Louisville, Kentucky, on March 13 by police who were conducting a “no-knock” search warrant. Elijah McClain died at the age of 23 on Aug. 24, 2019, when he was walking home and stopped by Aurora, Colorado, police, was detained and put in a chokehold and administered ketamine by paramedics.George Floyd, a 46-year-old Black man, was killed while in police custody in Minneapolis on Memorial Day after former police officer Derek Chauvin put his knee on Floyd’s neck for nearly nine minutes.ABC News’ Hayley FitzPatrick contributed to this report.Copyright © 2020, ABC Audio.

Titans honor six officers from Nashville Christmas Day explosion at playoff game

first_imgJanuary 11, 2021 /Sports News – National Titans honor six officers from Nashville Christmas Day explosion at playoff game Written by Beau Lundcenter_img FacebookTwitterLinkedInEmailMetropolitan Nashville Police DepartmentBy JON HAWORTH, ABC News(NASHVILLE, Tenn.) — The Tennessee Titans honored the six first responders responsible for safely evacuating residents in downtown Nashville, Tennessee prior to the Christmas Day bombing.Officers Brenna Hosey, Tyler Luellen, Michael Sipos, Amanda Topping, James Wells and Sergeant Timothy Miller were in attendance at Sunday’s NFL playoff game against the Baltimore Ravens and plunged the Titans Sword of Honor to mark the countdown to kickoff and were recognized as the game’s honorary 12th Titans, according to the Tennessee Titans.“While we can never thank these officers enough for their heroic acts, it is an absolute privilege to have the opportunity to honor them at the game on Sunday,” said Titans president and CEO Burke Nihill. “We are grateful for their service to our community and appreciate that we’ll have them on site to support the team.”Nashville police officers were called to downtown Nashville early on Christmas morning when they discovered an RV playing a recording saying a potential bomb would detonate within 15 minutes.The officers immediately began working to evacuate nearby buildings when the RV exploded at approximately 6:30 a.m, blowing out windows of nearby buildings and causing extensive and structural damage to dozens of buildings in the surrounding area.Authorities found human remains among the debris of the explosion and investigators eventually determined that they belonged to the RV owner who was later identified as 63-year-old Anthony Quinn Warner of Antioch, Tennessee, a suburb of Nashville.Eight people were injured in the blast. Warner was the only person to die in the blast.The Nashville police officers were hailed as heroes at a press conference a couple of days later.“Immediately, they didn’t think about their own lives. They didn’t think about themselves. They thought about the citizens of Nashville and protecting them, and they went about knocking on doors,” Chief John Drake said, as he introduced five of the six officers. “Had they not made those efforts, we’d be talking about the tragedy of people and lives lost.”On Sunday, however, the officers were lauded on the national stage.“To be able to stand at the stadium with [my fellow officers] and receive this honor together is amazing,” said Officer Wells. “[Our response on Christmas Day] was a total team effort. It was not what one individual did or said, it was about all of us coming together to protect our community, and keep our community safe and keep each other safe.”The Titans, the fourth seed in the AFC, went on to lose Sunday’s game to the fifth seeded Ravens, 20-13.

(Credit: Free-Photos/Pixabay) Canada-based energy company TC Energy is planning to go ahead with the Elwood Power/ANR Horsepower Replacement Project.The project will replace, upgrade and modernize certain facilities along a highly utilised section of the company’s ANR Pipeline Company (ANR) natural gas transmission system.The ANR natural gas transmission system is expected to provide approximately 125,000 Dth/d of firm transportation service to an existing power plant as part of the long-term agreement.TC Energy president and CEO Russ Girling said: “The facilities are designed to enhance the safety and reliability of our ANR pipeline system while reducing emissions.“This investment will serve to reinforce a key portion of our ANR pipeline network in the Midwest allowing us to maximize its capacity to support increased power generation, and highlights the opportunities for organic growth along our existing right-of-way.”TC Energy expects to complete the project in the second half of 2022In additional to compression and ancillary upgrades, the facilities work includes other modifications along ANR’s existing infrastructure.The $400m project is scheduled to commenced operations in the second half of 2022.In May this year, TC Energy has completed the sale of a 65% equity interest in the Coastal GasLink natural gas pipeline project to private equity firms KKR and Alberta Investment Management Corporation.The Coastal GasLink pipeline project is a 670km of gas pipeline, which is being developed in British Columbia, Canada.It is being developed by LNG Canada, which is a joint venture between four major energy companies that include Shell, PETRONAS, PetroChina, Mitsubishi Corporation, KOGAS.last_img read more

Signs of change

first_imgPurplebricks, EasyProperty, Hatched – online agents are snaffling all the headlines, giving the Martian, arriving from space in January, the idea that traditional estate agencies have been consigned to history.Purplebricks says it will float on the AIM market for £230 million, easyProperty has now banked funding totaling £39.25 million and Sequence has paid an undisclosed but ‘significant’ sum to acquire Hatched, saving them the trouble of creating their own ‘online’ brand.Traditional agents need to research the competition and maybe adjust their services to survive – and thrive.The figures are eye-watering; massive faith in unproved businesses, dramatic headlines about how much sellers will save, gleeful predictions of the imminent death of ‘rip-off agents.’But is it real? Is that nosy house-hunting Martian going to find defunct estate agencies on every high street? Is he going to find thousands of listings for homes on online agency sites?CEO of easyProperty, Rob Ellice, says, “This new, very substantial investment is a significant step for easyProperty; the most widely recognised consumer brand in a very fragmented estate agency market.” However, since the orange fanfare blew 15 months ago, there has been a lot of noise, but when you visit their website, they have just (on one day in December 2015) 183 properties across the UK.Hatched may grow dramatically with Sequence, but it too has a way to go, with around 320 properties listed.PurpleBricks’ flotation looks likely to be a roaring success, they currently list over 4000 homes for sale, making it the largest in our review of 30 online agencies by quite a stretch, leaving the longer established Tepilo trailing with 1000 listings, a figure that has declined by 30 per cent in recent months.House Network reported that one London homeowner is ‘set to save £172,000 on the sale of his property, listed at £8 million, by selling through them, but if it doesn’t sell, he will lose his ‘few hundred pounds’ – actually a £599 basic plus extras for such things as calls from a negotiator. Established for 11 years, they report sales of 10,000 homes, about 17 homes per week, but few others give any idea of how many homes they have actually sold. Indeed, listings seem to be their main focus, but surely, if they were completing hundreds of sales, they would boast about it? Maybe not, as they make their money by listing, not sales.The threat of disruption is shouted out, but people are asking questions about the services offered; the un-returnable upfront payment; the difficulties in covering the entire country from one base.Any traditional agent who doesn’t research the competition (from any source) has his head in the sand, but good high street agents will adjust their services, their marketing and their fee structures to survive… and thrive.TECHNOLOGYFuture homes in 3DBattersea Power Station Development Company (BPSDC) has announced the creation of new 3D immersive technology which allows potential buyers to take an interactive walk through the 42 acre development site with 360º views – years before completion.The team used an interactive solution created by Cityscape Digital based on gaming technology to create a first for a large scale London development. The software enables visitors at the marketing suite at Battersea Power Station to discover all that the new town centre will offer including the restored iconic Power Station and new buildings with world class architecture, surrounded by 18 acres of open space.Georgia Sri, Head of UK Residential Sales, said, “Battersea Power Station’s new fully immersive technology allows both potential residents to fully experience this incredibly exciting project, several years before completion. Battersea is a whole new town centre with new homes, shops, restaurants and offices. This unique experience offers our visitors the ability to step into this new world and imagine themselves really living or working at Battersea.”Hatched online agencies Purple Bricks Battersea Power Station technology easy Property future homes January 20, 2016The NegotiatorWhat’s your opinion?
