In a pilot study at the University of Helsinki, dogs trained as medical diagnostic assistants were taught to recognize the previously unknown odor signature of the COVID-19 disease caused by the novel coronavirus. And they learned with astonishing success: After only a few weeks, the first dogs were able to accurately distinguish urine samples from COVID-19 patients from urine samples of healthy individuals.
"We have solid experience in training disease-related scent detection dogs. It was fantastic to see how fast the dogs took to the new smell," says DogRisk group leader Anna Hielm-Björkman. After only a short time, the animals identified the urine of people infected by the novel coronavirus, known as SARS-CoV-2, almost as reliably as a standard PCR test.
The Finnish scientists are now preparing a randomized, double-blind study in which the dogs will sniff a larger number of patient samples. Only then will the scent tests be used in clinical practice.
Important Findings for Other Teams
The very rapid and promising findings from Finland are also important for other research teams, such as those in Great Britain and France, who are training sniffer dogs to detect COVID-19.
Fellow researchers from the German Assistance Dog Center (TARSQ) have also benefited from the Finnish results.
"No one could tell us with certainty whether training with the aggressive virus is dangerous or not for humans and dogs. We wanted to gather more information first before we started training because the German virologists advised us against it — after all, so little is known about the virus so far," explains Luca Barrett from TARSQ.
Where Does the Characteristic Smell Come From?
It is still unclear which substances in urine produce the apparently characteristic COVID-19 odor. Since SARS-CoV-2 not only attacks the lungs, but also causes damage to blood vessels, kidneys and other organs, it is assumed that the patients' urine odor also changes. This is something which the dogs, with their highly sensitive olfactory organs, notice immediately.
Certain diseases appear to have a specific olfactory signature that trained dogs can sniff out with amazing accuracy, Barrett says.
"According to one study, dogs can detect breast cancer with a 93% probability, for example. And lung cancer with a 97% probability," she says.
But dogs can also identify skin cancer, colon cancer, ovarian cancer or prostate cancer very reliably, according to Barrett. "The hit rate, which was not so good in the early days of training, has risen enormously in recent years," she says.
Hit Rate Decisive
Besides cancer, the dogs can also detect Parkinson's disease. Parkinson's sufferers smell different even years before they have the disease. "That's how we came up with the idea of training dogs as an early warning system for Parkinson's," Barrett says.
Dogs are also trained to detect malaria, but the hit rate is not yet satisfactory, she says. So far, the dogs recognize seven out of 10 infected persons, which is not enough.
A high hit rate is, of course, also absolutely necessary when training for the aggressive SARS-CoV-2 pathogen, according to Barret. "We hope that the hit rate for the coronavirus is significantly higher in the fully trained dogs; after all, it would be very dangerous if COVID-19 were not detected," she says
Trained Tracking Dogs
Dogs' ability to smell is about a million times better than that of humans. Humans have about 5 million olfactory cells, compared with 125 million for dachshunds and 220 million for sheepdogs.
Dogs also inhale up to 300 times per minute in short breaths, meaning that their olfactory cells are constantly supplied with new odor particles. In addition, dogs' noses differentiate between right and left. This spatial sense of smell allows the animals to follow a trail more easily.
During the training sessions, the dogs — mostly Labrador retrievers or retrievers in general, but also cocker spaniels or sheepdog breeds — are each trained for one scent. That can be the smell of a drug or an explosive, or, as here, the olfactory signature of a specific disease.This means that one dog cannot recognize several types of cancer.
The animals are trained with containers holding samples of breath or sweat, for example. As soon as they have identified the smell they are looking for, the dogs hear a click and get a treat. They are reliably trained for the one smell on this reward principle.
Great Potential, Great Skepticism
Drug and explosive detection dogs have been used for some time. But trained medical scent detection dogs are also now working in hospitals. For example, they sniff the bodies of patients with suspected skin cancer to try and detect the disease — only with the patients' consent, of course. So these skilled snufflers are helping doctors in diagnosing diseases and detecting them early on.
However, so far there are only very few medical detection dogs. The dog owners almost always work voluntarily and the trained sniffer dogs live in normal households. There is great skepticism, especially among traditional doctors and health insurance companies, even though the first indications given by the dog have to be followed by further medical tests anyway and a lot of time and costs could be saved by early cancer detection.
Possible Coronavirus Applications
If the findings from Finland are confirmed, the sniffer dogs with their extremely sensitive sense of smell could prove to be a great help in the fight against the new coronavirus.
Luca Barrett from TARSQ can easily picture coronavirus sniffer dogs being used in situations where there is a high risk of infection. For example, people attending football matches and other major events could be checked before they are admitted.
The dogs could also be employed at airports to scan people entering a country. "When the dogs go down the queue, they can detect if someone is healthy and can enter the country. But if a person smells of COVID-19, the handler could send that person to a coronavirus testing center instead," Barrett says. That is because a second test is still needed to confirm the dog's initial sniff detection.
Barrett says dogs could also be used to search for the virus on surfaces. For example, before passengers board an aircraft, a four-legged friend could first check whether the machine is free from SARS-CoV-2. Similar measures are planned for doctors' surgeries, aged care homes or nursing homes that have had to be evacuated because of COVID-19 cases. Before these are used again, a sniffer dog could check whether the environment is "clean."

This week, Secretary Haaland chose a visit to Bears Ears National Monument as her first trip as Interior Secretary. She is spending three days in Bluff, Utah, a small town just outside the monument, listening to representatives of the five tribes who first proposed its designation to President Obama in 2015. This is the same town where former Secretary Sally Jewell spent several hours at a public hearing in July 2016 before recommending the monument's designation to President Obama.

The tropical water at the equator is renowned for having the richest diversity of marine life on Earth, with vibrant coral reefs and large aggregations of tunas, sea turtles, manta rays and whale sharks. The number of marine species naturally tapers off as you head towards the poles.
The Bell Curve is Warping Dangerously<img class="rm-lazyloadable-image rm-shortcode" lazy-loadable="true" data-runner-src="https://assets.rebelmouse.io/eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpbWFnZSI6Imh0dHBzOi8vYXNzZXRzLnJibC5tcy8yNjAzODUwNi9vcmlnaW4ucG5nIiwiZXhwaXJlc19hdCI6MTY3NzE1OTU4N30.qQL3P1IvA7Cwj_UbsrAL6MVZvafXGZc7hlAFieLPvso/img.png?width=980" id="9bbfd" width="1580" height="872" data-rm-shortcode-id="16ca57badee20ad55037706875f813f4" data-rm-shortcode-name="rebelmouse-image" />
If you look at each line in this chart, you can see a slight dip in total species richness between 1955 and 1974. This deepens substantially in the following decades. Anthony Richardson, Author provided<p>This global pattern — where the number of species starts lower at the poles and peaks at the equator — results in a bell-shaped gradient of species richness. We looked at distribution records for nearly 50,000 marine species collected since 1955 and found a growing dip over time in this bell shape.</p>
This Has Happened Before<p>We shouldn't be surprised global biodiversity has responded so rapidly to global warming. This has happened before, and with dramatic consequences.</p><p><strong>252 million years ago…</strong></p><p>At the end of the Permian geological period about 252 million years ago, global temperatures warmed by 10℃ over 30,000-60,000 years as a result of greenhouse gas emissions from volcano eruptions in Siberia.</p><p><a href="https://www.pnas.org/content/117/30/17578" target="_blank" rel="noopener noreferrer">A 2020 study</a> of the fossils from that time shows the pronounced peak in biodiversity at the equator flattened and spread. During this mammoth rearranging of global biodiversity, 90% of all marine species were killed.</p><p><strong>125,000 years ago…</strong></p><p><a href="https://www.pnas.org/content/109/52/21378" target="_blank" rel="noopener noreferrer">A 2012 study showed</a> that more recently, during the rapid warming around 125,000 years ago, there was a similar swift movement of reef corals away from the tropics, as documented in the fossil record. The result was a pattern similar to the one we describe, although there was no associated mass extinction.</p><p>Authors of the study suggested their results might foreshadow the effects of our current global warming, ominously warning there could be mass extinctions in the near future as species move into the subtropics, where they might struggle to compete and adapt.</p><p><strong>Today…</strong></p><p><a href="https://www.pnas.org/content/117/23/12891" target="_blank" rel="noopener noreferrer">During the last ice age</a>, which ended around 15,000 years ago, the richness of forams (a type of hard-shelled, single-celled plankton) peaked at the equator and has been dropping there ever since. This is significant as plankton is a keystone species in the foodweb.</p><p>Our study shows that decline has accelerated in recent decades due to human-driven climate change.</p>
The Profound Implications<p>Losing species in tropical ecosystems means ecological resilience to environmental changes is reduced, potentially compromising ecosystem persistence.</p><p>In subtropical ecosystems, species richness is increasing. This means there'll be species invaders, novel predator-prey interactions, and new competitive relationships. For example, <a href="https://www.abc.net.au/news/2019-09-13/sydney-growing-own-coral-reef-with-help-from-tropical-fish/11466192" target="_blank">tropical fish</a> moving into Sydney Harbour compete with temperate species for food and habitat.</p><p>This could result in ecosystem collapse — as was seen at the boundary between the Permian and Triassic periods — in which species go extinct and ecosystem services (such as food supplies) are permanently altered.</p><p>The changes we describe will also have profound implications for human livelihoods. For example, many tropical island nations depend on the revenue from tuna fishing fleets through the selling of licenses in their territorial waters. Highly mobile tuna species are likely to move rapidly toward the subtropics, potentially beyond sovereign waters of island nations.</p><p><span></span>Similarly, many reef species important for artisanal fishers — and highly mobile megafauna such as whale sharks, manta rays and sea turtles that support tourism — are also likely to move toward the subtropics.</p><p>The movement of commercial and artisanal fish and marine megafauna could compromise the ability of tropical nations to meet the <a href="https://sdgs.un.org/goals" target="_blank">Sustainable Development Goals</a> concerning zero hunger and marine life.</p>
Is There Anything We Can Do?<p>One pathway is laid out in the Paris Climate Accords and involves aggressively reducing our emissions. Other opportunities are also emerging that could help safeguard biodiversity and hopefully minimise the worst impacts of it shifting away from the equator.</p><p>Currently 2.7% of the ocean is conserved in <a href="https://mpatlas.org/" target="_blank">fully or highly protected reserves</a>. This is well short of the 10% target by 2020 under the UN Convention on Biological Diversity.</p><p>But <a href="https://www.gov.uk/government/topical-events/global-ocean-alliance-30by30-initiative/about#global-ocean-alliance-members" target="_blank">a group of 41 nations</a> is pushing to set a new target of protecting 30% of the ocean by 2030.</p><p>This "30 by 30" target could ban seafloor mining and remove fishing in reserves that can destroy habitats and release as much carbon dioxide as <a href="https://www.nature.com/articles/s41586-021-03371-z" target="_blank">global aviation</a>. These measures would remove pressures on biodiversity and promote ecological resilience.</p><p>Designing climate-smart reserves could further protect biodiversity from future changes. For example, reserves for marine life could be placed in refugia where the climate will be stable over the foreseeable future.</p><p>We now have evidence that climate change is impacting the best-known and strongest global pattern in ecology. We should not delay actions to try to mitigate this.</p><p><em><a href="https://theconversation.com/profiles/anthony-richardson-100303" target="_blank">Anthony Richardson</a>: Professor, The University of Queensland. <a href="https://theconversation.com/profiles/chhaya-chaudhary-1223419" target="_blank" rel="noopener noreferrer">Chhaya Chaudhary</a>: University of Auckland, <a href="https://theconversation.com/profiles/david-schoeman-111544" target="_blank" rel="noopener noreferrer">David Schoeman</a>: Professor of Global-Change Ecology, University of the Sunshine Coast, <a href="https://theconversation.com/profiles/mark-john-costello-1223418" target="_blank" rel="noopener noreferrer">Mark John Costello</a>: Professor, University of Auckland</em></p><p><em>Disclosure statement: Anthony Richardson receives funding from the Australian Research Council.</em></p><p><em>Chhaya Chaudhary works for Goethe University, Frankfurt am Main, Germany.

The coronavirus has isolated many of us in our homes this year. We've been forced to slow down a little, maybe looking out our windows, becoming more in tune with the rhythms of our yards. Perhaps we've begun to notice more, like the birds hopping around in the bushes out back, wondering (maybe for the first time) what they are.

1. Choosing the Right Binoculars<p>Binoculars are a relatively indispensable tool for most birders – but, for those just starting out, it might not yet be worth the several-hundred-dollar investment. If you aren't able to scour the attics of friends or borrow a pair from a fellow bird watcher, some local birding and naturalist groups have <a href="https://vashonaudubon.org/all-about-vashon-birds/binoculars-check-out/" target="_blank">binocular loaning programs</a> for members, allowing you to plan ahead for a day (or week) of birding.</p><p>When you're ready to take the plunge, choosing a pair or binoculars should take some careful deliberation based on your needs and preferences; some <a href="https://www.birdwatchersdigest.com/bwdsite/explore/optics/top-10-tips-buying-binoculars-bird-watching.php" target="_blank">major considerations</a> might include size, ease of use, <a href="https://www.rei.com/learn/expert-advice/binoculars.html" target="_blank" rel="noopener noreferrer">magnification</a>, and price. While professional binoculars can easily run north of $1,000, there are plenty of perfectly suitable entry-level binoculars under $200. You might not get the perfect precision and clarity of more elite models, but a less expensive pair will allow you to strengthen your birding skills while deciding if you're interested in investing in a premium pair.</p><p>For a budget-friendly option, check out resale options on eBay, Facebook marketplace, or neighborhood yard sales: you might find a nicer pair whose retail price isn't within your budget.</p>
2. Know What Birds Are in Your Area<p>When I began to pay more attention to the birds just outside my apartment building, I started to learn what species have always been around me: European starlings, house sparrows, blue jays, black capped chickadees, and the occasional red-bellied woodpecker. They had always been there, but I hadn't ever taken the time to identify them. Once you learn to <a href="https://www.audubon.org/news/get-know-these-20-common-birds_" target="_blank" rel="noopener noreferrer">recognize common birds</a> in your area, you'll be able to identify the typical species right outside your window and in your community. Of course, permanent residential birds in your neighborhood will <a href="https://nestwatch.org/learn/focal-species/" target="_blank" rel="noopener noreferrer">vary by region</a>, as will those migrating through it.</p>
3. Get Out and Explore<p>Venturing elsewhere might allow you to spot some different species beyond those frequenting your backyard. Anywhere with water or greenery offers a place for birding; as an urbanite myself, I've found that even small- and mid-sized parks in New York City allow me to find more elusive birds (although Central Park takes the crown for an afternoon of urban birding).</p><p>If you are able to travel a bit further from home, <a href="https://www.fws.gov/refuges/" target="_blank">national wildlife refuges</a> and <a href="https://www.americasstateparks.org/" target="_blank" rel="noopener noreferrer">state/national parks</a> are excellent places to explore bird habitats and perhaps log some less-common sightings. The American Birding Association also lists <a href="https://www.aba.org/aba-area-birding-trails/" target="_blank" rel="noopener noreferrer">birding trails by state</a>, and Audubon and BirdLife International identify <a href="https://www.audubon.org/important-bird-areas" target="_blank" rel="noopener noreferrer">Important Bird Areas (IBAs)</a> across the country – important bird habitats and iconic places that activists are fighting to protect – where birders can spot birds of significance.</p>
4. Finding a Bird: Stop, Look, Listen, Repeat<p>The National Audubon Society recommends the "<a href="https://www.audubon.org/news/how-find-bird" target="_blank">stop, look, listen, repeat</a>" mantra when seeking and identifying birds.</p><p>First and foremost, spotting birds requires attention. Stopping – getting out of the car, pausing on the sidewalk, trail, or in the backyard to look up – is the most important step.</p><p>When looking for birds, try to avoid gazing wildly around; rather, scan your surroundings, focusing on any odd shapes or shadows, trying to think about where a bird might perch (power lines, fence posts, branches), or keep an eye on the sky for flying eagles and hawks. In open areas like fields and beaches, you might have a more panoramic view, and can take in different sections of the landscape at a time. Look around with the naked eye before reaching for the binoculars to hone in.</p><p>While it can be hard to sift through the noise, listening for birds is perhaps an even more important element of bird watching than looking. Once you spend more time in the field, you'll be able to parse apart the racket and identify specific species, especially aided by Audubon's Bird Guide app or by learning from their <a href="https://www.audubon.org/section/birding-ear" target="_blank">Birding by Ear series</a>.</p><p>Repeat this pattern as you continue on your way, stopping to look and listen for birds as you go, rather than waiting for them to come to you. </p>
5. Identification<p>When you head out for a day of bird watching – especially when you're hoping to spot some new species – you'll want to be armed with the tools to identify what you see. <a href="https://www.audubon.org/news/how-identify-birds" target="_blank" rel="noopener noreferrer">Major considerations when identifying birds</a> are their group (such as owls, hawks, or sparrow-like birds), size and shape, behavior, voice, field marks, season, and habitat.</p><p>The <a href="https://www.sibleyguides.com/about/the-sibley-guide-to-birds/" target="_blank" rel="noopener noreferrer">Sibley Guide to Birds</a> and the <a href="https://www.hmhbooks.com/shop/books/peterson-field-guide-to-birds-of-north-america-second-edition/9781328771445" target="_blank" rel="noopener noreferrer">Peterson Field Guide</a> are widely considered the best books for identifying birds in North America, although many <a href="https://www.audubon.org/news/what-bird-guide-best-you" target="_blank" rel="noopener noreferrer">specialized guides</a> focus on specific species or regions as well.</p><p>Plenty of <a href="https://blog.nature.org/science/2013/05/27/boucher-bird-blog-apps-smart-birder/" target="_blank" rel="noopener noreferrer">bird identification apps</a> have popped up in recent years – including National Geographic Birds, Sibley eGuide to Birds, iNaturalist, Merlin Bird ID, and Birdsnap – which are basically a <a href="https://www.audubon.org/news/the-best-birding-apps-and-field-guides" target="_blank" rel="noopener noreferrer">field guide in your pocket</a>. I'm partial to the Audubon Bird Guide, which allows users to filter by common identifiers, including a bird's habitat, color, activity, tail shape, and general type, adding them all to a personal map to view your sightings.</p>
6. Recording Your Sightings<p><span>As you deepen your commitment to birding, you might join the community of birders that track and quantify their sightings, building their </span><a href="https://www.thespruce.com/what-birds-count-on-a-life-list-386704#:~:text=A%20life%20list%20is%20a,which%20birds%20you%20have%20seen." target="_blank" rel="noopener noreferrer">life list</a><span>.</span></p><p>While a standard notebook noting the date, species name, habitat, vocalizations, or any other data you wish to include will suffice, some birders opt for a more <a href="https://www.riteintherain.com/no-195-birders-journal" target="_blank" rel="noopener noreferrer">structured birder's journal</a> with pre-determined fields to record your encounters, take notes, draw sketches, etc.</p><p>Many birders also choose to record their sightings online and in shared databases (which include many of the field guide apps), often pinpointing them on a map for others to view. Launched by the Cornell Lab of Ornithology and Audubon, <a href="https://ebird.org/home" target="_blank" rel="noopener noreferrer">eBird is one of the largest databases and citizen science projects around birding</a>, where hundreds of thousands of birders enter their sightings, and users can explore birds in regions and hotspots around the world. Users can also record their sightings on the <a href="https://apps.apple.com/us/app/ebird/id988799279" target="_blank" rel="noopener noreferrer">eBird app</a>.</p>
7. Attracting Birds to Your Own Yard<p>Feeding birds is a common phenomenon: more than 40% of Americans maintain a birdfeeder to attract birds and watch them feast.</p><p>Not all birdfeed is created equal, however. Many commercial varieties are mostly made with "fillers" (oats, red millet, etc.) that birds will largely leave untouched. After researching what birds to expect in your area – and which ones you want to attract – you can create your own birdfeed with <a href="https://www.allaboutbirds.org/news/types-of-bird-seed-a-quick-guide/?pid=1142" target="_blank">seeds that will appeal to them</a>.</p><p>Beyond filling a birdfeeder, <a href="https://www.ecowatch.com/eco-friendly-lawn-2651194858.html" target="_self">transforming your yard into an eco-friendly oasis</a> is by far the best way to attract birds. Choosing to forgo mowing your lawn, planting native flowers and grasses, and ditching the pesticides will bring back the bugs that birds feed on, and provide a safe haven in which birds can happily live and eat.</p><p>While it's widely considered acceptable – and even beneficial – to feed birds with appropriate seeds, communal birdfeeders often <a href="https://www.audubon.org/news/to-feed-or-not-feed" target="_blank" rel="noopener noreferrer">foster unlikely interactions between different species</a>, who can then transmit harmful diseases and parasites to one another. Maintaining several bird feeders with different types of seeds might keep different species from coming into contact, and feeders can be <a href="https://www.allaboutbirds.org/news/how-to-clean-your-bird-feeder/" target="_blank" rel="noopener noreferrer">cleaned to prevent the spread of infection</a>.</p>
8. Inclusivity and Anti-Racism in the Birding Community<p>Like all outdoor activities and areas of scientific study, birding communities are subject to racist and discriminatory ideologies. Black birders have long experienced discrimination and underrepresentation in outdoor spaces. The work of organizations like the <a href="https://www.instagram.com/birdersfund/" target="_blank">Black & Latinx Birders Fund</a>, <a href="https://www.instagram.com/birdability/" target="_blank">Birdability</a>, and <a href="https://www.instagram.com/feministbirdclub/" target="_blank">Feminist Bird Club</a> highlight the contributions and importance of birders of color, birders with disabilities, and women and LGBTQ+ birders to the birding community, as do activists and naturalists like <a href="https://www.instagram.com/hood__naturalist/" target="_blank">Corina Newsome</a> and <a href="https://www.instagram.com/tykeejames/" target="_blank">Tykee James</a>. The work of <a href="https://www.audubon.org/news/its-bird-new-comic-written-central-park-birder-christian-cooper" target="_blank">Christian Cooper</a>, <a href="https://camilledungy.com/publications/" target="_blank">Camille Dungy</a> (read her poem <a href="https://www.poetryfoundation.org/poetrymagazine/poems/58363/frequently-asked-questions-10" target="_blank">Frequently Asked Questions: 10</a>), and <a href="https://orionmagazine.org/article/9-rules-for-the-black-birdwatcher/" target="_blank">J. Drew Lanham</a> – including his essay "<a href="https://lithub.com/birding-while-black/" target="_blank">Birding While Black</a>" – are a great place to start.</p><p>Getting involved in birding means educating ourselves on these issues and taking meaningful action; the work of <a href="https://www.audubon.org/news/its-bird-new-comic-written-central-park-birder-christian-cooper" target="_blank">Christian Cooper</a> and <a href="https://orionmagazine.org/article/9-rules-for-the-black-birdwatcher/" target="_blank">J. Drew Lanham</a> – including his essay "<a href="https://lithub.com/birding-while-black/" target="_blank" rel="noopener noreferrer">Birding While Black</a>" – are a great place to start. Just as birders are activists for protecting habitats and natural areas, we must also be active and aware of inclusivity in these spaces.</p>
9. Get Involved<p>To learn from and enjoy the company of other birders, check out local birding groups in your area to join. Many Audubon chapters host trips, meetings, and bird walks for members. The American Birding Association even maintains a <a href="https://www.aba.org/festivals-events/" target="_blank">directory of birding festivals</a> across the country.</p><p>Volunteering for birds is also a great way to meet other birders and take action for birds in your community; local organizations might have opportunities for assisting with habitat restoration or helping at birding centers.</p><p>Like all wildlife, climate change and habitat destruction threaten the livelihood of birds, eliminating their breeding grounds and food sources. A <a href="https://www.audubon.org/climate/survivalbydegrees" target="_blank">2019 report released by the National Audubon Society</a> found that two-thirds of North American birds may face extinction if global temperatures rise 5.4 degrees Fahrenheit by 2100. Staying informed about and taking action for legislation designed to protect birds and our climate – such as the recent <a href="https://www.congress.gov/bill/116th-congress/house-bill/5552/text" target="_blank" rel="noopener noreferrer">Migratory Bird Protection Act</a> – is important for ensuring a livable future for wildlife and humans alike.</p><p><em>Linnea graduated from Skidmore College in 2019 with a Bachelor's degree in English and Environmental Studies, and now lives in Brooklyn, New York.
