New species of flying frog discovered in Vietnam
New species of flying frog discovered in Vietnam
Helen’s Flying Frog was first discovered by Jodi Rowley, an amphibian expert from Sydney’s Australian Museum, in 2009 during a field trip to the forests fringing the city previously known as Saigon.
Rowley initially thought the tree-dwelling flying frog, so named for the huge webbed feet that allow it to glide or parachute across the forest canopy, was a familiar species when she saw it sitting on a log beside a path.
It was not until a later trip, when she saw a specimen of the original type of frog in another part of Vietnam, that she realized her creature was something quite different.
“The new species has a bright white belly and white whites of the eyes, whereas the species that I thought it was — its closest relative — has a lemon yellow belly and yellow whites of the eyes,” Rowley told AFP.
“There’s also differences in the color of the webbing, color of the thighs, and we did look at body type as well so it does seem to be bigger than the other species.”
Molecular analysis confirmed Rowley’s suspicions and she had the honor of naming the new species rhacophorus helenae or Helen’s Flying Frog after her mother, who had recently been diagnosed with ovarian cancer.
She said the “big, impressive” species, which is 10 centimeters (four inches) long was a surprising find in the low-lying evergreen forest surrounded by rice paddies on the fringes of Ho Chi Minh City, Vietnam’s most populous city.
“What’s rare about this discovery in particular is the fact that I found the lone individual less than 90 kilometers from the middle of Ho Chi Minh City, one of the biggest cities in Southeast Asia,” said Rowley.
Researchers are now working to establish whether Helen’s frog is endangered. Specimens have only been seen in the lowland forests of southern Binh Thuan and Dong Nai provinces and Rowley said there were real fears for its survival.
“We are worried particularly because it is a lowland forest and it’s the same kind of forest (as where) the Javan rhinoceros went extinct in 2011 as well. Habitat loss is a huge issue,” she said.
Rowley’s discovery, made with researchers from Ho Chi Minh city’s University of Science, was published in the latest issue of the Journal of Herpetology.
Instagram unveils new video service in challenge to YouTube
- Video will be available through Instagram or a new app called IGTV
- Before, Facebook and Instagram have copied Snapchat — another magnet for teens and young adults
SAN FRANCISCO: Facebook’s Instagram service is loosening its restraints on video in an attempt to lure younger viewers away from YouTube when they’re looking for something to watch on their smartphones.
The expansion announced Wednesday, dubbed IGTV, will increase Instagram’s video time limit from one minute to 10 minutes for most users. Accounts with large audiences will be able to go as long as an hour.
Video will be available through Instagram or a new app called IGTV. The video will eventually give Facebook more opportunities to sell advertising.
It’s the latest instance in which Instagram has ripped a page from a rival’s playbook in an effort to preserve its status as a cool place for young people to share and view content. In this case, Instagram is mimicking Google’s YouTube. Before, Facebook and Instagram have copied Snapchat — another magnet for teens and young adults.
Instagram, now nearly 8 years old, is moving further from its roots as a photo-sharing service as it dives headlong into longer-form video.
The initiative comes as parent company Facebook struggles to attract teens, while also dealing with a scandal that exposed its leaky controls for protecting users’ personal information.
Instagram CEO Kevin Systrom told The Associated Press that he hopes IGTV will emerge as a hub of creativity for relative unknowns who turn into Internet sensations with fervent followings among teens and young adults.
That is what’s already happening on YouTube, which has become the world’s most popular video outlet since Google bought it for $1.76 billion nearly 12 years ago. YouTube now boasts 1.8 billion users.
Instagram, which Facebook bought for $1 billion six years ago, now has 1 billion users, up from 800 million nine months ago.
More importantly, 72 percent of US kids ranging from 13 to 17 years old use Instagram, second to YouTube at 85 percent, according to the Pew Research Center. Only 51 percent of people in that group now use Facebook, down from 71 percent from a similar Pew survey in 2014-15.
That trend appears to be one of the reasons that Facebook is “hedging its bets” by opening Instagram to the longer-form videos typically found on YouTube, said analyst Paul Verna of the research firm eMarketer.
Besides giving Instagram another potential drawing card, longer clips are more conducive for video ads lasting from 30 seconds to one minute. Instagram doesn’t currently allow video ads, but Systrom said it eventually will. When the ads come, Instagram intends to share revenue with the videos’ creators — just as YouTube already does.
“We want to make sure they make a living because that is the only way it works in the long run,” Systrom said.
The ads also will help Facebook sustain its revenue growth. Total spending on online video ads in the US is expected to rise from nearly $18 billion this year to $27 billion in 2021, according to eMarketer.
Lele Pons, a YouTube sensation who also has amassed 25 million followers on Instagram, plans to launch a new cooking show on IGTV in hopes of increasing her audience and eventually generating more revenue. “It’s like Coca-Cola and Pepsi,” she said. “You will never know what you like better unless you try both.”
IGTV’s programming format will consist exclusively of vertical video designed to fill the entire screen of smartphones — the devices that are emerging as the main way younger people watch video. By contrast, most YouTube videos fill only a portion of the screen unless the phone is tilted horizontally.
Snapchat began featuring vertical video before Instagram, another example of its penchant for copying rivals.
But Systrom sees it differently. “This is acknowledging vertical video is the future and we want the future to come more quickly, so we built IGTV.”
