Mountain Birds on ‘Escalator to Extinction’ as Planet Warms

A meticulous re-creation of a three-decade-old study of birds on a mountainside in Peru has given scientists a rare chance to prove how the changing climate is pushing species out of the places they are best adapted to.

Surveys of more than 400 species of birds in 1985 and then in 2017 have found that populations of almost all had declined, as many as eight had disappeared completely, and nearly all had moved to higher elevations in what scientists call “an escalator to extinction.”

“Once you move up as far as you can go, there’s nowhere else left,” said John W. Fitzpatrick, a study author and director of the Cornell Laboratory of Ornithology. “On this particular mountain, some ridgetop bird populations were literally wiped out.”

It’s not certain whether the birds shifted ranges because of temperature changes, or indirect impacts, such as shifts in the ranges of insects or seeds that they feed on.

These findings, published recently  in the Proceedings of the National Academy of Sciences, confirm what biologists had long suspected, but had few opportunities to confirm. The existence of a 1985 survey of birds on the same mountain gave scientists a rare and useful baseline.

Past research has documented habitats of birds and other species moving up in elevation or latitude in response to warming temperatures. But Mark Urban, director of the Center of Biological Risk at the University of Connecticut, who was not involved in the study said it was the first to prove what climate change models predicted: that rising temperatures will lead to local extinctions.

“A study like this where you have historical data you can go back to and compare is very rare,” said Urban. “As long as the species can disperse, you will see species marching up the mountain, until that escalator becomes a stairway to heaven.”

In 1985, Fitzpatrick established a basecamp alongside a river running down a mountain slope in southeastern Peru, aiming to catalog the habitat ranges of tropical bird species that lived there. His team spent several weeks trekking up and down the Cerro de Pantiacolla, using fine nets called mist nets to catch and release birds, and keeping detailed journals of birds they caught, spotted or heard chirping in the forests.

Two years ago, Fitzpatrick passed his journals, photos and other records to Benjamin Freeman, a postdoctoral fellow at the Biodiversity Research Centre at the University of British Columbia. Freeman, who has been researching tropical birds for more than a decade, set out to recreate the journey in August and September of 2017. Using old photos of mountain views, his team located the same basecamp.

Freeman largely recreated Fitzpatrick’s path and methodology to see what had happened in the intervening years, a period when average mean temperatures on the mountain rose 0.76 degrees Fahrenheit (0.42 degrees Celsius). Because the mountain lies at the edge of a national park, the area hadn’t been disturbed.

In addition to unfurling 40-foot (12-meter) mist nets on the slopes, Freeman’s team placed 20 microphone boxes on the mountain to record the chirps of birds that might not easily be seen.

“We found that the bird communities were moving up the slope to reach the climate conditions to which they were originally adapted,” said Freeman, the lead author of the study. Near the top of the mountain the bird species moved higher by 321 feet (98 meters), on average.

“We think temperature is the master-switch in explaining why species live where they do on mountain slopes,” said Freeman. “A huge majority of species in our study were doing the same thing.”

Birds adapted to live within narrow temperature bands — in regions without wide seasonal variations — may be particularly vulnerable to climate change, Fitzpatrick said.

“We should expect that what’s happening on this mountaintop is happening more generally in the Andes, and other tropical mountain ranges,” he said.(Source: VOA NEWS)

Probable Guidelines for Lockdown 5.0.

More travel routes are likely to open in Lockdown 5.0.

From June 1, the Railways will operate 100 pairs of mail or express trains, bookings have already begun. Then AC class services will resume.

Some states have already begun intra-state buses. Other states may  begin intra-tate bus services after June 1.Metro  services may begin in a limited manner, with lesser passenger capacity, social distancing norms and longer stops at each station.

Shops selling non-essential items were allowed to open during Lockdown 4.0.. More shops may open in Lockdown 5.0 even in markets.But no confirmed news regarding opening of shopping malls.Now many shops that have re-opened in market areas are operating on an odd-even basis.

How to identify Fake News or Messeges on Social Media 

Beware of Fake News and Fake Messages on Social Media

Always follow websites or social media platforms of traditional media outlets whether newspapers, magazines,Television News Channels or Radio Stations and authentic online only media outlets.They still maintain journalism excellence and stress on reportorial talent.On the other hand, fake news websites run by people with non journalism background and promote their own ideology with fake news and disinformations and obviously conspiracy theories.

But unfortunately mainstream media also manipulates news to establish their story angle.There were various instances when News papers and TV Channels promoted fake news/conspiracy theories in the form of out of context or manipulated pictures/videos and distorted informations.

Always check the URL of any website.Some fake news websites look like the orginal and popular one the same layout,Logo but if you check the URL you may find extra words like if the orginal website's URL is www.xxx.com the duplicate one might be www.xxx.com.co or something like that so first check the URL for authentic informations.

Check whether photos are original or photoshopped.Check Google images for authenticity.You can find help from Google Reverse Images search.

Check the news sources from other websites whether they picked up the story or not.

Whether the website layout is little bit clumsy and obviously grammatical mistakes and spelling mistakes and excessive use of Sex related and sensational and hate stories.Because sex and hate sells.

Follow official websites relating to COVID-19

WHO Clarifies the disinformation about the virus:
COVID-19 virus can be transmitted in areas with hot and humid climates
Cold Weather and Snow can not kill the new coronavirus
Taking a Hot Bath Does Not Prevent COVID-19
COVID-19 Can not be transmitted through mosquito bites

Spraying alcohol or chlorine all over your body will not kill viruses that have already entered your body. Spraying such substances can be harmful to clothes or mucous membranes (i.e. eyes, mouth)

According to World Health Organization (WHO): Regularly and thoroughly clean your hands with an alcohol-based hand rub or wash them with soap and water

Maintain at least 1 metre (3 feet) distance between yourself and anyone who is coughing or sneezing.

Avoid touching eyes, nose and mouth . If you have fever, cough and difficulty breathing, seek medical care early

Stay at home if you begin to feel unwell, even with mild symptoms such as headache and slight runny nose, until you recover.

If you develop fever, cough and difficulty breathing, seek medical advice promptly as this may be due to a respiratory infection or other serious condition

Follow WHO guidelines

www.who.int

When you follow COVID-19 related news and messages from social media then check and recheck it before consuming it.Follow journalism mantra: if your mother says she loves you, check it out.

Most of the messages or informations quote different organizations like WHO, UNICEF, UNDP,Cambridge University  or other well known institutes,organizations or individual to authenticate the messeges.Check official websites of these organizations  if stories are repeated there

Forwarding messages from unknown sources or little known sources, it would be better to ignore it.

Check whether any logo like UNICEF or WHO or other organizations used in the messages which look similar to original logo.

These type of messages are full of Grammatical mistakes and spelling mistakes which are quite uncommon in original messages.

Don't rely on viral social media messages such as Coronavirus Infected Indian Currencies of Rs.500 and Rs.2,000 Notes Found, Muslim Man Spit in Food At Indian Restaurant.....Always Check Authentic Sources.

Some fake messages pretend to be real one like unofficial Twitter handle of international media organizations like BBC,CNN,Washinton Post, New York Times-check the official Twitter handles of media outlets.

You can identify fake messages if the message requests you to share it.

Beware of Fake News or Fake Photos/Videos Relating to Communal Hatred

Always check the fact checking sites if you have some doubts about the authenticity of any information or picture.
