Cool birds don’t sing: Study automates acoustic monitoring of songbird migration

first_imgResearchers have developed machine learning techniques to identify bird song from thousands of hours of field recordings, using the information to uncover variations in migratory songbirds’ arrival to their Arctic breeding grounds.They deployed automated listening devices during spring over five years, analyzed vocal activity to estimate when birds arrived at their breeding sites, and assessed relationships between vocal activity and environmental conditions.They found that the acoustically derived estimates of the birds’ arrival dates were similar to those determined using standard field surveys.Temperature and presence of snow affected the birds’ calling patterns, suggesting that collecting corresponding weather data could help avoid bias in using acoustic monitoring to assess population dynamics. It’s June, and migratory songbirds in the northern hemisphere are at their summer breeding grounds, having traveled thousands of miles from their warm-weather overwintering areas.Birds migrate as far north as the Arctic to take advantage of its large but short-lived surge in insect food and its few predators. The timing of their arrival is critical because their breeding cycles must match seasonal food availability for their chicks to survive.Migratory Lapland longspurs endure the cold en route to their breeding grounds. Image by Andy Reago & Chrissy McClarren, CC 2.0Scientists have shown that as spring temperatures rise, many bird populations are, in fact, migrating north and arriving earlier in the season at their breeding sites, where climate-related shifts in breeding-ground conditions, including environmental conditions and food availability, may help or hinder reproduction of individual species.Most songbirds are too small to carry GPS tracking tags scientists would typically use to follow their migrations north, but they do call intensely once they arrive there in preparation for breeding.To study trends in migration timing, scientists have begun setting out microphones to listen for particular species or the bird diversity at specific sites. Placing numerous relatively inexpensive acoustic listening devices in the field allows researchers to better monitor wildlife communities in remote places and across larger scales than field surveys typically can.Gambel’s white-crowned sparrows, like this one, prefer woody shrubs. As the Arctic continues to warm, shrubs on Alaska’s North Slope are expected to overtake open grasslands. That could create conditions for sparrows to outcompete longspurs and other migratory birds. Image by John WingfieldA multi-institutional research team deployed automated listening devices over five spring breeding seasons at sites in Alaska to capture the vocalizations of two common breeding songbird species. White-crowned sparrows (Zonotrichia leucophrys) and Lapland longspurs (Calcarius lapponicus) both fly to these sites each spring to mate and raise their young.Autonomous recorders in the field can collect data 24/7, and their use has relied on trained experts to listen to the recordings and detect a target species or tally the species present at a given site. However, automated recordings of whole bird communities over hours or days produce data sets too large to review manually.Automating analysis of birdsong patternsTo facilitate the use of acoustic devices in studying whole communities of breeding birds, the researchers developed automated signal processing and machine learning algorithms adapted from human speech research to estimate from acoustic signals when songbird communities arrived each spring at four breeding sites in Alaska. For five seasons (2010 to 2014), the research team recorded songbird vocalizations at the sites at regular intervals from early May through July.An acoustic recording unit near Toolik Field Station in arctic Alaska. Image by Heather GreavesThey developed and trained a supervised machine learning algorithm, one that includes human input, to pick out calls of target songbirds from thousands of hours of field recordings that also contained noise from trucks, wind, rain, mosquitos and other bird species. They used the call data to produce a daily community Vocal Activity Index (VAI), a relative measure of the abundance of bird vocalizations at each site. They analyzed the daily VAI values to estimate the dates that the bulk of these birds had arrived at their breeding sites and any relationships between the VAI and environmental conditions, including temperature, wind and snow cover.The researchers also analyzed the sound data using an unsupervised classification, which does not use listener input but classifies data into groups that represent like items, to see if it could pick out the bird songs on its own and use them to estimate the arrival date.Cool birds don’t singThe researchers found that songbird vocal activity varied both in time (days, weeks and years) and the surrounding environment.They state in their paper, “We found that daily fluctuations in snow cover, air temperature, wind speed, atmospheric pressure, and precipitation had a significant impact on the VAI and explained a large proportion of variance.”A Lapland longspur singing near Toolik Field Station in arctic Alaska. Image by John WingfieldIn particular, they found calling activity increased noticeably on snow-free days, and they suggest that birds rely on snow-free patches of tundra for food and shelter. Singing takes energy, even more so on colder days; the songbirds in this study either moved on or remained quiet during unfavorable weather.They also found that both the supervised and the unsupervised arrival date estimates closely approximated what human observers recorded at the sites.Tools to study a range of calling creatures The success of the automated analyses is good news for researchers studying animal movements and population dynamics and could help scientists better understand patterns of migration and how they may be adapting to changes in climate patterns.“These tools could speed up the analysis of acoustic datasets packed with biodiversity information valuable to conservationists and others,” Andrew Farnsworth, a researcher at the Cornell Lab of Ornithology, who was not involved in the study, said in a statement. “Understanding the dynamics of songbird arrival and breeding timing is the doorway to thinking about climate change and how temperature, weather and snowfall are affecting various species.”Listen to a Gambel’s white-crowned sparrow singing near Toolik Field Station in arctic Alaska.

An unsupervised automated analysis does not need to be trained with a reference database of calls, as it does not need to be told what it is hearing.“Our methods could be retooled to detect the arrival of birds and other vocal animals in highly seasonal habitats,” said the study’s lead author, Ruth Oliver, a graduate student at Columbia University. “This could allow us to track large-scale changes in how animals are responding to climate change.”The study also showed that acoustic monitoring must consider environmental factors, such as temperature, that may influence how much animals call and thus lead to biased conclusions, as the listening devices cannot distinguish silence from absence.“Our findings demonstrate that the correct interpretation of avian vocal activity to estimate relative songbird abundance requires pairing of acoustic data collection with meteorological data, as well as consideration of the study communities’ breeding phenology [breeding stage].”“It’s still unclear how songbirds will cope if spring comes even earlier or later than it did during our study period,” said co-author Natalie Boelman. “Species also time their migration and breeding with day length, which isn’t shifting with climate change. Species whose migratory response is hard-wired to day length alone may not adapt as well to a changing environment.”CitationOliver, R., Ellis, D., Chmura, H., Krause, J.S., Pérez, J.H., Sweet, K.S., Gough, L., S.

There is no need to even have to agree or disagree with it, because, you also mentioned the fact that Cauvery Calling aims to plant trees only in the private lands of the farmers. So, plantation in the common lands doesn’t come into the picture.2.I don’t see that the ecologists are totally against this project, but just they they have some concerns, mainly in terms of what species of trees will be planted. And because there was no direct communication between the ecologists and Isha Foundation, it was not possible for them to address the concerns. As you seem to have spoken with an Isha spokesperson, if you could connect the concerned parties, it would be great, because I see that the ecologists are genuinely interested in making sure things are done the right way.May we all come together and make things happen.Rare Amazon bush dogs caught on camera in BoliviaCarrot1 Feba very good iniciative to be fallowed by the ranchers all overSponsoredlast_img read more

Europa League not to blame for defeat, says Pochettino

Tsogo Sun in $100m African expansion

first_img29 April 2013South African hotel and casino group Tsogo Sun is to invest $100-million (about R900-million) in projects in Mozambique and Nigeria as part of its African growth strategy.The Southern Sun Maputo in Mozambique will get a $30-million (R270-million) revamp of the existing 158-room hotel, as well as the addition of 110 rooms and conferencing facilities.“The Mozambican economy has shown encouraging signs of growth in recent years, and Tsogo Sun has benefited from a strong trading at the Southern Sun Maputo,” Tsogo Sun chief executive, Marcel von Aulock, said in a statement last Wednesday.“The group has for some time been planning to utilise the additional land owned next to the hotel and believe that this exciting expansion programme will cement the Southern Sun Maputo as the destination hotel of choice in the city.”Approximately $70-million (R630-million) will go towards the Nigerian project. It involves the acquisition of a 75% stake in Ikoyi Hotels Limited, the holding company of the Southern Sun Ikoyi hotel in Lagos.The hotel has been managed by Tsogo Sun since it opened in 2009, but the acquisition is subject to regulatory approvals. Shareholders will be notified once the acquisition has become effective.“This acquisition will cement our presence within the fast growing and progressive Nigerian economy as well as provide a base from which to expand our operations in Nigeria,” Von Aulock said.The Southern Sun Ikoyi hotel is centrally located with access to prime business nodes in Lagos and has additional land available for expansion.Tsogo Sun currently operates hotels in seven African countries, including South Africa, Mozambique, Zambia, Tanzania, Kenya, Nigeria and the Seychelles.SAinfo reporterlast_img read more

Police thrillers: Khaki is the newest hue in Bollywood

Its majestic Indo-Saracenic central hall doubling as a post office after working hours is littered with broken furniture,GANGAAJAL: In Prakash Jha’s film, Ajay Devgan dons the uniform and plays an honest officer who takes on the baddiesViolence reverberates through the grimy, paan-stained corridors of Mumbai’s Directorate of Technical Education. Its majestic Indo-Saracenic central hall doubling as a post office after working hours is littered with broken furniture because Akshay Kumar in police uniform is trading filmi punches with Ajay Devgan.A biff and a bang later, director Rajkumar Santoshi yells “cut”, ending the pantomime on the sets of one of Bollywood’s biggest blockbusters, Khakee. The days Santoshi spent as chief assistant director to Govind Nihalani, tramping through the city’s police stations to recreate the filthy rooms and the rough police speak in the classic Ardh Satya, have stood him in good stead. The star-spangled Khakee, he promises, will be Bollywood’s closest look at the men in the force. Amitabh Bachchan is the honest IPS officer, Devgan the bad guy, Akshay is crooked and comic, and Tusshar Kapoor is the rookie. Trouble is there are a dozen films waiting in the wings, each promising to do just that. Not all of them have Khakee’s stellar line-up, but they collectively have more than Rs 100 crore riding on their back and a range of actors – from the Union shipping minister to a superbrat – in dust brown fabric packing a pistol. From Sunny Deol who grew a beard to play a rustic Sikh constable dispatched to New York in Jo Bole So Nihal to Nana Patekar playing a hardened encounter specialist in the Ram Gopal Varma factory’s Ab Tak Chappan. The call of duty has attracted even bad boy Salman Khan who, sample this for sheer irony, marched straight to the sets in starched uniform after being jailed for nearly a fortnight for mowing down a pavement dweller. Producer Sunil Mehta hasn’t decided what to call the Rs 25 crore film-Satyameva Jayate or Garv- but swears it is “Salman’s best performance till date”. Actors, evidently, are in short supply for such heavy duty acting. advertisementSATYAMEVA JAYATE Or may be Garv. The Khan brothers Salman Khan (right) and Arbaaz Khan team up as policemenShool’s steely officer Manoj Bajpai reprises the role in two films-Pankuj Parashar’s Inteqam and Mehul Kumar’s Jaago, based on the true story of a rape in a Mumbai local train. Three Khakee stars are doing double-shifts as law enforcers in other films-Devgan has just played Gangaajal’s upright officer while Bachchan hops sets to play policeman in Dev, Santoshi’s one-time mentor Govind Nihalani’s film. Akshay Kumar, who plays a conscientious officer in the Madhur Bhandarkar-directed Aan, sits in crisp uniform amid Khakee’s chaos and confesses with the frankness of a child in a candy store, “I read both scripts at around the same time, both were exciting.” The film’s other hero, Union Minister for Shipping Shatrughan Sinha, had to seek prime ministerial approval, no less, to don greasepaint and khaki. But producer Firoz A. Nadiadwala believes his Weapon of Mass Distraction will be Paresh Rawal who sparked off laugh riots in Hera Pheri. His barbs as the bribe-taking constable are specially penned by Neeraj Vora. Bollywood, used to herd-mentality, is dumb founded by the khaki deluge. “This hasn’t happened in the industry before, but it is no trend,” says trade analyst Amod Mehra. “Santoshi, Varma and Nihalani are serious film-makers, not proposal makers.” Varma wanted to make a film on the encounter specialists in the Mumbai Police. “They get a strange sense of achievement in numbers,” he says, explaining his film’s title, Ab Tak Chappan. “But each statistic represents a dead criminal. It is macabre.” After the superlative Ardh Satya and Drohkaal comes Dev where Nihalani realises his “ambition to work with Bachchan”. He won’t call it the last of his police trilogy but a “story of two friends who happen to be policemen”. DEV: In his third police film, Govind Nihalani (centre) fulfils his dream of working with Amitabh Bachchan (left) and casts him opposite the peerless Om PuriAs an after thought, he says it may be “the Ardh Satya for the new millennium”. Anurag Kashyap, scriptwriter of Shool and Satya, who is to direct Black Friday, a police procedural film on the 1993 Bombay blasts, and Allwyn Kalicharan on a corrupt policeman, Anil Kapoor, in a dystopic Delhi of 2015, explains the police obsession: “It is a fascination for the cop- and crime-genre and people who have the power to do the unthinkable and change lives.”Mumbai policemen are a richly mined vein- encounter specialist sub-inspector Daya Nayak inspires characters in Aan, Ab Tak Chappan and Kagaar while Kay Kay plays Additional Commissioner Rakesh Maria in Black Friday. In these all-male films, women are adornments-recruited for oomph, as Lara Dutta is in Aan, or to play a suffering wife like Gracy Singh in Gangaajal. Unless, of course, it is a policewoman played by Sushmita Sen in Samay, a serial-killer flick. “She is the woman in control,” says director Robby Grewal. The khaki wave even promises to do the unthinkable-be authentic. Former police commissioner M.N. Singh, who had a hitlist of films that showed his department in poor light, had to eat his words when he mistook Akshay Kumar-sporting a close crop and in a uniform stitched by the Mumbai Police’s official tailor-for one of his men at the mahurat of Aan. Designer Anna Singh saw her home deluged with bales of brown fabric when she agreed to design uniforms, over a 1,000 of them, for Santoshi’s film. “He is a perfectionist and wanted all the policemen dressed in the same shade of khaki,” says Singh. Bachchan’s IPS uniform had to be aged by 10 years by washing it every day for two months. Onscreen, however, khaki is the newest hue.advertisementlast_img read more

Perth Test one of the best matches of my career: Faf du Plessis

first_imgSouth Africa Test captain, Faf du Plessis, has described the 177-run win against Australia in the first Test at the WACA ground in Perth as ‘the best Test match of my career’. (Scorecard)The Proteas put in a spirited performance with only two seamers after the injury to Dale Steyn, and to go one-up in the three-match series which moves to Hobart later this week. (Kagiso Rabada takes five as South Africa hammer Australia in Perth Test) “For my career that I’ve been involved in that is one of the most special days,” Du Plessis said to the media after the match. “To turn it around 360 degrees after day one when we were under the pump and under a lot of pressure, and in the position that we were in to turn it around on day two was one of the best days of cricket that I have been involved in. (Australia opener Shaun Marsh ruled out of second Test vs South Africa) “To be a seamer down pretty much the whole Test match and to do what we have done; we always joke that if you lose a seamer in a three-seam attack it’s 99 per cent impossible to win a Test match because there is just too much of a workload on the bowlers. (Clarke, Johnson, Taylor slam DRS after Perth Test) “Somehow we managed to do it, obviously there is a lot of credit that must go to Kagiso Rababa, who has put up his hand and bowled really well, and also Keshav (Maharaj), he was the guy who relentlessly bowled in a good area and made sure we could rotate the guys from the other end and build a bit of pressure. That is right up there as one of the best Test matches of my career.”advertisement(Reuters Photo) Du Plessis was full of praise for his tenacious bowling unit, who never backed down despite the high workload and long spells on the final day. He made a special mention of the never-say-die attitude of man-of-the-match, Kagiso Rabada, who put in his longest spell of bowling at international level to lead from the front in the absence of Steyn.   “I’m incredibly proud of him,” he said of Rabada. “I have a lot of respect for anyone who puts up their hand and does the hard yards. KG just wanted the ball, every time I asked him if he was tired or done he said ‘no, you’re not taking the ball out of my hand’. That is a sign of a champion bowler for me, someone who wants to be in the fight the whole time and wants to make sure he does the hard work.”The second Test will be played at the Bellerive Oval in Hobart from November 12.last_img read more

Research offers clue on how females stay healthier than males despite eating

first_imgReviewed by James Ives, M.Psych. (Editor)Oct 24 2018New research from York University on fat tissue is providing an important clue as to how females stay healthier than males, even as their body fat increases.Published today in Frontiers in Physiology – Vascular Physiology, the research focusses on the differences between abdominal fat in obese male and female mice. A team of researchers under the direction of Professor Tara Haas found that the abdominal fat on female mice had more blood vessels than the fat on male mice, and that this protected the health of the female mice as they gained fat from eating a high-fat diet.Males and females develop fat tissue differently and also differ in susceptibility to cardiovascular disease, insulin resistance and diabetes. However, the underlying biology behind why fat tissue in females is more protective against these conditions was not well understood, says Haas, a professor in the School of Kinesiology and Health Science, Faculty of Health.Related StoriesObese patients with Type 1 diabetes could safely receive robotic pancreas transplantUCR biomedical professor to investigate how body’s cannabis-like molecules influence obesityMetformin use linked to lower risk of dementia in African Americans with type 2 diabetesBlood vessels are critical for maintaining healthy fat tissue by ensuring that the expanding fat cells are supplied with enough oxygen and nutrients, so the researchers looked at whether the abilities of the fat tissue to grow blood vessels and maintain healthy fat tissue would be different between males and females.”We found that female mice have a higher number of blood vessels in their fat than males, and that females increase the number of blood vessels as they are fed a high fat diet, while males do not. We concluded that this response enabled females to maintain healthier fat and better insulin sensitivity,” says Haas.Martina Rudnicki, a York post-doctoral associate and first author of the study, pointed out that the study was unique because it focused on the differences in male and female fat tissue in the abdominal area. Although fat accumulates in different regions of the body, it is abdominal fat that is closely linked with increased risk of developing diabetes, particularly in males. So, the fact that females grow new blood vessels in this abdominal fat during weight gain may exert a health advantage for females.The sex differences in the fundamental cellular processes that regulate the growth of blood vessels were unappreciated in the past, said Haas. It is important to understand them because they may contribute to an individual’s susceptibility to develop serious obesity-related health complications such as diabetes, heart disease and cancer, ultimately impacting the health of more than 5.3 million Canadian adults.The research team plans to confirm these findings in human samples. While it is clear that females also develop health problems with obesity, the fact that there was such a difference in the vascularization in male and female fat may mean it would be more effective to have different treatments for males and females.Source: http://news.yorku.ca/2018/10/23/york-u-study-sheds-light-on-differences-between-male-and-female-fat-tissue-and-health-implications/last_img read more

Childrens Colorado granted IACs Cardiovascular Catheterization accreditation

Tired of passwords Single Signon could be savior

Apple hopes to go a little deeper, by using the Face ID and Touch ID biometrics features of the iPhone and iPad to bypass those clicks. If a website or app asks for an e-mail address, Apple will “create a unique email address that forwards to your real one,” the company says.So how is single sign-on more secure, if Facebook is in charge? It’s not, say security experts. “They’ve shown they can’t be trusted with our information,” says Rudis.Google, however, is more trustworthy and Apple the best of the trio, he adds, due to its public commitment to privacy.Both are super convenient. Who wouldn’t rather click a Facebook or Google icon instead of having to type in your name and password, once again?But not everyone we spoke with was in agreement that we can let our back down and forget about tough passwords.Even Google, on its website, recommends 8 characters minimum, and combinations of letters, numbers and symbols. Apple has the same requirements, with at least one number minimum. “You can also add extra characters and punctuation marks to make your password even stronger,” the company says.”You can also make the password more complex by making it longer with a phrase or series of words that you can easily remember, but no one else knows,” says Facebook.Andy Halverson, who runs IT for video firm Ooyala, looks to a password manager, and lets it create and remember the hard passwords, so he doesn’t have to. He uses the password manager Dashlane, but there are many other popular ones, including Lastpass and 1Password.”I like single sign-on, but this is another tool, and really convenient,” he says.James Litton, the CEO of security firm Identity Automation doesn’t think single sign-on achieves much. “If it’s a horrible password, your security situation hasn’t improved,” he says.He likes super long passwords, as many as 32 to 64 characters, but stored in a password manager. With a manager, you type in one master password, and the software logs you in.”It’s more difficult for a bad guy to pick words out of a dictionary for a hack attack if I go long,” he says.Meanwhile, for now, Rudis says a combination of long passwords and a password manager will lead to us “to that nirvana of being able to sign on with a single sign-on,” everywhere.It will take time. First, Apple will have to convince hundreds of thousands of websites to add its single sign-on system, which won’t be easy. Apple, Google and Facebook have huge sales jobs ahead. For instance, while you can sign on to Barnes and Noble and Kroger with Google, that option isn’t available on many top websites, including Target, Walmart, American Airlines, Verizon Wireless and Home Depot. Struggling to come up with long strings of complex capital and lower case letters, numbers and symbols? That’s so yesterday.That’s the hope, anyway.In a fascinating interview with Google product manager Mark Risher in The Verge this week, he laid out his vision for why those passwords we’ve been told to create don’t actually help.They have “no bearing on phishing, no bearing on password breaches, no bearing on password reuse,” he said. “We think that it’s much more important to reduce the total number of passwords out there.”In other words, all that time you’ve been forced to spend trying to create tougher to crack passwords is a waste. At least that’s the way he appears to see it.I think all Talking Tech readers would agree that anything we could do to eliminate the constant typing of passwords during our daily hours would be most welcome.But how to get there?Google wants you to use its single sign-on feature, which still requires a password and has Google authenticate your identity, for a second layer of authority, via text messages or via the Google smartphone app.Apple just announced its answer to Google’s sign-in, with an alternative that will be introduced to the iPhone and iPad in the fall, as part of the iOS13 software upgrade. Google has an 85.% market share for its Android phone system, to 14.9% for Apple, according to market tracker IDC.”Between the two of them, that’s pretty much everyone’s phone system,” says Bob Rudis, the Chief Data Scientist for security firm Rapid 7. “So most everyone will get this by default over the next 18 to 36 months.”Facebook and Google have for years been offering consumers the ability to ditch having to recall their multiple passwords, and instead use their single sign-on system for gaining entry to websites. These tools don’t even require the input of screen name and passwords, just a click of the “Sign in with” Facebook or Google tab.last_img read more
