According to the ASPCA, 3.3 million dogs enter shelters each year in the United States. Although that number has gone down since 2011 (from 3.9 million) there are still millions of dogs waiting in shelters for a forever home. As May 20th is National Rescue Dog Day, here are 25 benefits of adopting a shelter dog.

1. Adopting a dog means you won't be supporting puppy mills.

If you go to a pet store or to a disreputable breeder to buy that adorable puppy, it's entirely possible that it's from a puppy mill, where dogs are kept in terrible conditions. By adopting a rescue, you can help lower the demand for puppies from puppy mills.

2. You can find almost any breed you want.

Is your heart set on a specific breed? There's a wide network of breed-specific rescues out there. Just spend a little time online and you can get the dog of your dreams without resorting to buying from puppy mills.

3. Shelter dogs are eager to follow your lead.

A 2016 study that appeared in Journal of Veterinary Behavior: Clinical Applications and Research analyzed problem solving in dogs in homes (what they called "pet dogs") versus shelter dogs. The researchers found that although pet dogs are better at following human pointing, shelter dogs "seem to be more socially driven to gaze and interact with humans" when compared with pet dogs, which they say is likely due to the shelter dogs' "generally limited and poor-quality contact with humans." But the researchers also pointed out that with increased human exposure, the shelter dogs were trainable.

4. A rescue dog might help you get a date.

According to Slate, one survey found that "82 percent of people [felt] more confident approaching an attractive person if they had their dog with them." Another study cited by Slate found that in the modern world of dating apps, people with dogs look more approachable and happy than those who are dogless.

5. You can share your audiobook collection with them.

There have been several studies on the best ways to calm dogs in kennels [PDF]. Classical music seems to work well, but a 2016 study found that compared to other "auditory conditions," kenneled dogs were more relaxed while audiobooks were playing. Cesar Milan then did his own tests and found that 76 percent of his volunteer dogs were more relaxed at home while listening to audiobooks—and teamed up with Audible to create a specialized audiobook service. Just be careful: soon your rescue pup will be better read than you.

6. Rescue dogs can transform in dramatic ways in a forever home.

Thanks to those heart-wrenching ASPCA/Sarah McLachlan commercials, everyone is familiar with how sad a dog can appear in a shelter. But once adopted, dogs' attitudes can change dramatically. In 2008, Italian researchers published a paper about a shelter dog named Daisy that they placed into a facility for people suffering from Alzheimer’s disease. Although in the shelter Daisy had groomed so much that she developed a skin lesion, in the six months that she lived at the facility, her over-grooming lessened, she was healthy, and she "displayed no aggressive or sexual behavior, even when in heat." And the calming effect seemed to go both ways: the researchers reported, the people in the facility experienced "many positive effects of Daisy's presence."

7. Shelter pets come with benefits.

Whether you get your pet at a breed-specific rescue or from a normal shelter, you'll often have access to resources about your fuzzy new family member, and maybe even classes on how best to take care of them.

8. Shelter dogs are typically up-to-date on all their shots.

Depending on the shelter, shelter dogs may already be vaccinated and microchipped (or the shelter will perform these services for a small fee)—which means you can get straight to cuddling your new pet instead of making vet appointments.

9. Shelter dogs may also already be spayed or neutered.

More than half of states have laws requiring "releasing agencies" (a.k.a. shelters) to spay or neuter dogs they adopt out. While the pet sometimes isn't fixed until you adopt it, frequently it's already been spayed or neutered. Check with your local adoption center.

10. By adopting a dog, you're helping to keep the unwanted pet population down.

If you happen to adopt a dog that isn't fixed, you can still help prevent pet overpopulation (especially in the wild) by keeping it in the house and away from other unfixed dogs of the opposite sex. (But seriously, get your pets fixed!)

11. Rescue dogs may be easier to housetrain.

Many adult shelter dogs are already housebroken when you adopt them. But because the dog may have a history that prevented such training (such as never being allowed inside the house), you shouldn't go in expecting a house-trained pet. If your new pupper isn't house-trained, there are resources out there that can help you reach that goal; many say that adult dogs have an easier time getting the hang of it.

12. Adopt and older dog and you can skip the puppy stage.

Yes, puppies are adorable. They're also full of energy and require a lot of time, training, attention, and patience. It can be tough to fit an energetic puppy into a hectic life. Adopting an older dog from a shelter allows you to skip the puppy stage altogether, which can mean an easier transition from not having a pet to being a pet owner. It also (hopefully) means you may avoid having your slippers, running shoes, pillows, furniture, and doors gnawed on by sharp little puppy teeth.

13. If you adopt an older dog, you'll have a better idea of their temperament.

An analysis of many studies found that the "personality" of an adult dog is fairly consistent. Puppies, on the other hand, can change personality a fair amount, especially when it comes to "responsiveness to training, fearfulness, and sociability." So by getting an adult dog, you have a better idea of what the animal's personality is truly like.

14. A shelter can help match you with a dog that best reflects your personality.

Because adult dogs are generally more fixed in their personalities, many adoption centers have matching programs that help the process of pairing dog and human. The ASPCA claims the programs have dramatically improved successful adoptions at some shelters.

15. You'll feel more involved in the community.

According to a 2013 study, dog owners over 50 who walked their dogs felt a higher sense of community. So adopting a dog can help you connect to your neighbors.

16. A dog can improve your health.

A study of Mexican dog owners versus non-dog owners found that the dog owners felt that they were healthier: "Compared to non–dog owners, the dog owners' scores were significantly lower for psychosomatic symptoms and stress and were higher for general health, vitality, emotional role, absence of bodily pain, social functioning, and mental health."

17. Your kids will play more if you have a dog.

It's not just adults who experience health benefits from having a dog; another study found that child dog walkers played outside more and were more likely to walk in the neighborhood.

18. Adopting a pet helps small wild animals.

As one of the most common predators in human areas, dogs can easily do great harm to local wildlife. By keeping dogs out of the wild (whether that's the city or the countryside), you can help reduce the numbers of truly wild animals that are preyed upon by what are supposed to be pets.

19. Adopting a dog can limit the spread of disease.

Feral dogs can also have disastrous effects on wild animals in regards to disease. For instance, the black-footed ferret was nearly driven to extinction by canine distemper. By keeping dogs out of the environment and up-to-date on all their necessary shots and vaccinations, adopters help many other animals, too.

20. You could have a movie star on your hands.

A surprising number of actual canine movie stars came from shelters. The original Benji was adopted from a shelter; Rudy, one of the 22 dogs that played Marley in the film Marley and Me, was just 24 hours away from being put down before he was rescued; and Spike, the star of Old Yeller, was adopted from Van Nuys Animal Shelter, supposedly for $3.

21. A rescue dog might have experience living in a home, making the move from shelter to your home an easier transition.

Some shelters have foster programs, where the dog is sent out to live with a volunteer in an actual house. Not only does this give the dog a chance to be away from the shelter, but it gives the humans looking after the pup a chance to see how the dog reacts in a less controlled environment—hopefully making the future forever home transition easier.

22. Even volunteering to foster has its benefits.

If you're not quite ready to adopt, consider fostering, which has a number of benefits for you and for the dogs you're housing. According to one researcher, overweight participants in a "loaner" dog walking program lost an average of 14 pounds because they felt "the dogs need us to walk them." Other participants in a community dog walking program were inspired to increase their exercise even when they weren't walking dogs.

23. You can help shelters modernize.

Shelters across the country are modernizing their facilities—which can sometimes be a very expensive prospect. The adoption fee you pay to the shelter to take your dog home will help the facility get the resources to give future dogs a better shelter experience.

24. By adopting a dog, you're saving at least one life.

By giving a dog in a shelter a second chance, you can make sure it has a great life.

25. In reality, you're probably saving more than one life.

By adopting a dog, you open up a space in the shelter that can be filled by another future pet. And by supporting your local shelter, you help their mission to save many more.

But remember, a pet of any kind is a massive commitment. Some estimate that "more than 20 percent of people who leave dogs in shelters adopted them from a shelter." And studies have found that much of the problem is people not knowing what they're getting into. So make sure that you have the time and energy to devote to a pet, and do your research before adopting.

The Biologists and Activists Fighting to Save Endangered Tapirs in Costa Rica

Costa Rican biologist Esteban Brenes-Mora was just 5 years old the first time he saw a tapir, and he immediately fell in love with the large, unusual animal. "The tapir was walking on the beach close to Corcovado National Park," he says of the moment that helped impact his future career. "It was a highlight for me; it led me to do what I do now."

Twenty-five years later, Brenes-Mora is a tapir expert and founder of Nai Conservation, a Costa Rican organization that is working to save the endangered species from its worst enemy: humans. Tapirs have been around for some 35 million years, but deforestation, highways through its habitats, and poaching have caused their numbers to drop significantly. It's estimated that the population of the Baird's tapir as decreased by more than 50 percent in just the last three generations. And in turn, what hurts the tapirs hurts the environment.

"Tapirs are considered gardeners of the forests; they plant seeds and have a big impact on enriching the soil," Brenes-Mora explains. "The tapirs are even saving us from climate change. There's evidence from the Amazon that when tapirs are gone from certain forests, carbon sequestration in those forests decreases."

Experts have warned that tapirs, and specifically the Baird’s tapir that Brenes-Mora saw on that beach as a child, may soon be classified as critically endangered if current trends are not addressed.

Thankfully, Brenes-Mora has a plan.

 

I’m in Costa Rica on assignment to create an awareness-building film about the endangered tapir species. My colleague Alisha and I have just wrapped one week documenting the work of Nai Conservation, the local tapir research and conservation organization Brenes-Mora founded in 2015, and we're putting the final touches on our film in one of the most heavily tapir-populated (and protected) habitats, Corcovado National Park.

Of course, seeing a tapir in the wild would add an important element to our film, but even after a full week with the passionate, driven team behind Nai Conservation, we haven't seen even one.

This isn't surprising, though; few locals ever encounter the elusive tapir. The Baird's tapir—Tapirus bairdii, or known locally as danta in Spanish—is one of four tapir species in the region. It's indigenous to Central America and is a mammalian relative of the rhinoceros and horse, though it looks much more hog-like than either of the two (it has no relation to either boars or pigs). It is largely nocturnal and spends most of its day resting, hidden in the rainforests before foraging for fruits and berries in the afternoon. This makes spotting one in the wild even more rare, but Brenes-Mora and the Nai team want us to see a tapir as badly as we do.

Before launching Nai, Brenes-Mora spent six months in Malaysia after getting his biology degree, working with RIMBA, an NGO studying tigers, flying foxes, and other native wildlife. But since seeing that tapir on the beach when he was young, it had been his childhood dream to work with tapirs, and a fellowship with the Zoological Society of London gave him that chance. According to Brenes-Mora, the fellowships are meant to provide early-career conservationists and biologists an opportunity, through funding and mentorship, to get a foothold in their desired field. For him, that meant tracking tapirs through the highlands of Costa Rica's Talamanca Mountains.

One day in 2015, Brenes-Mora and a friend reached Cerro de la Muerte—Costa Rica's "mountain of death," the highest point on the mountain range. They were discussing creating a logo for the fellowship project, but Brenes-Mora’s friend saw longer-term potential.

"He was like 'whoa, you have more than a logo, you have more than a project, you can actually start something here,'" Brenes-Mora remembers.

And start something he did. The idea quickly evolved into the full-scale conservation project, Nai. (In the indigenous Bribri language of Costa Rica, nai means danta, or tapir.) Under Brenes-Mora's leadership, the organization is bringing together people with a variety of skills to raise awareness and preserve the tapir species. Nai's biologists and veterinarians perform critical, in-the-field research that informs tapir conservation action. The organization's teachers educate children on the tapir species as part of its "Salva-Dantas" program, which prepares youth for a lifetime of helping the tapir. And graphic designers and artists like Mauricio Sanabria, an artist who joined the team as a twentysomething in 2017, create eye-catching signs and other content to help spread the word about Nai—and ultimately the tapir—online and across local communities.

Over the past four years, this seed of a project has grown into a grassroots movement. The team's bright yellow "tapir crossing" stickers—the symbol of support for Nai—are popping up in restaurants, homes, and businesses throughout the country. One delicious example is in Costa Rica's capital city of San José, where Lucía Cole and Mauricio Varela, the founders of Tapir Chocolates, donate a portion of all profits to Nai.

And all the way down in the southwestern-most Osa Peninsula some 200 miles away, two of Nai's biggest supporters, Steven Masis and Deyanira Hernández, plan to guide us through the jungle in search of a tapir.

Masis and Hernández lead wildlife tours across the tropical Osa Peninsula, including through the country's popular, secluded Corcovado National Park. Both in their early thirties and with backgrounds in biology, Masis and Hernández join Nai and its partners on virtually all research trips through the remote, 160-square-mile park. Of all the places to spot tapirs in Costa Rica, Corcovado's dense, foggy rainforests—accessible only by boat or tiny plane—are the best bet. But even with their exceptional tapir-sighting success rate, these two activists don't take those sightings for granted.

Any encounter with the endangered tapir is rare and special. Due to threats like poaching (its hide is highly valuable on the black market), habitat loss, road kills, and trafficking, populations are plummeting throughout its Central American habitat. At this point, Brenes-Mora estimates only 1500 tapirs remain in Costa Rica, and research suggests that the total population of Baird’s tapirs in the entire region is only around 3000.

The possibility of losing the tapir species is problematic for planet Earth. The tapir holds a unique ecological "superpower" that’s becoming more important by the second: the ability to help combat climate change. They can eat over 200 pounds of fruit, plants, and seeds a day, and in the process, they essentially clear the forest floor, till the ground with their rummaging, and spread the seeds that they eat through transference and droppings. And they've been doing this for millions of years.

 

Despite the challenges, the tapir movement is not all doom and gloom. Earlier that week, I joined Nai for an afternoon installing "tapir crossing" road signs in central Costa Rica's Cerro de la Muerte mountains, and saw several indicators of success throughout the day.

For one, even erecting these street signs is progress. The team used trap-photo data and subsequent tapir and road traffic models to project exactly where traffic accidents occur most frequently, and they have used that data to convince the transportation department and local communities to allow tapir-crossing signs at high-risk sections along the busy Inter-American Highway, which runs right through tapir habitat.

"All of our decisions are based on actual data," Brenes-Mora says. "Based on that data, we start making decisions and lobby to include our ideas into policy.”

Brenes-Mora, a pragmatic biologist who has formed strong working relationships with key government leaders and NGOs, is hesitant to claim the decrease in road kills as a success just yet. A couple of years is not enough time to impact the population of a large mammal, he says (especially one with a 400-day gestation period for a single calf—repopulating the species will take a very long time).

But four years is enough time to create a widespread, engaging movement among locals. From Brenes-Mora's perspective, this unity surrounding the tapir is the ultimate success.

"Without people, it doesn't matter if we have protected areas, it doesn't matter if we're protecting the populations," he says. "Without engaging people, we won't be able to secure the species in the long term."

While Nai is his brainchild and tapirs are his lifeblood, Brenes-Mora doesn't want the future of Nai—or, more importantly, the tapir species—to depend solely on him.

"I'm always asking myself 'what will happen when I die?'" he muses. "I don't want tapirs to be unattended if something happens to me. I don't want to be the tapir guy, I want Nai to be the tapir group. I want all the members of the team to be the tapir people. It's hard to do that, but we're on the right track."

With the future in mind, Brenes-Mora is priming people like Nai research lead and team veterinarian Jorge Rojas, artist Mauricio Sanabria, and dozens of other dedicated team members to help carry the tapir mission forward. They tour and give talks, like at a recent weeklong event they hosted at the University of Costa Rica with the Costa Rica Wildlife Foundation, where Brenes-Mora and Rojas spoke at a symposium for students, professors, and activists about threats to tapirs, their importance to the environment, and how to best help and protect them.

That's why our trip down to Corcovado National Park is a milestone for the movement—the plight of the tapir is generally less known than that of the whale or tiger or rhino. Raising awareness about the tapir is one of its best chances at survival.

 

Alisha and I had originally planned to take the two-day Corcovado trek on our own, but after some consideration (and likely Brenes-Mores's urging, given the rough terrain we'd be facing—i.e. jungle off-roading), Sanabria joined us for a chance to see the animal he's been working so hard to save. For all the work he has done as a researcher and activist and the time he's spent in the field, he has yet to see a tapir in the wild.

Suddenly, our naturalist guide bursts from the forest yelling, "Un tapir! Un tapir!," and Sanabria takes off running. Despite the fact that Masis and Hernández see tapirs more regularly than most, they're leading our 100-yard blitz down the beach with him—smiling their "Christmas morning grins" every step of the way.

Finally, after much huffing and puffing, we've made it. We've caught up with our guides and are now face to face with the remarkable tapir we drove hundreds of miles to see.

We're awestruck and on adrenaline highs, but the tapir couldn't be less interested in the five of us. He offers a polite nod between super-sized mouthfuls of vegetation, but he has business to attend to—like strolling along the shoreline, urinating in the ocean, and then passing out in the sun.

Sanabria locks eyes with the now-sleepy tapir, and in a moment of near-solitude with the elusive creature, Sanabria can feel the magnitude of the work he's been doing.

"It's touching to finally see what you're working for," he says. "It's a little sign of hope."

Is There An International Standard Governing Scientific Naming Conventions?

Jelle Zijlstra:

There are lots of different systems of scientific names with different conventions or rules governing them: chemicals, genes, stars, archeological cultures, and so on. But the one I'm familiar with is the naming system for animals.

The modern naming system for animals derives from the works of the 18th-century Swedish naturalist Carl von Linné (Latinized to Carolus Linnaeus). Linnaeus introduced the system of binominal nomenclature, where animals have names composed of two parts, like Homo sapiens. Linnaeus wrote in Latin and most his names were of Latin origin, although a few were derived from Greek, like Rhinoceros for rhinos, or from other languages, like Sus babyrussa for the babirusa (from Malay).

Other people also started using Linnaeus's system, and a system of rules was developed and eventually codified into what is now called the International Code of Zoological Nomenclature (ICZN). In this case, therefore, there is indeed an international standard governing naming conventions. However, it does not put very strict requirements on the derivation of names: they are merely required to be in the Latin alphabet.

In practice a lot of well-known scientific names are derived from Greek. This is especially true for genus names: Tyrannosaurus, Macropus (kangaroos), Drosophila (fruit flies), Caenorhabditis (nematode worms), Peromyscus (deermice), and so on. Species names are more likely to be derived from Latin (e.g., T. rex, C. elegans, P. maniculatus, but Drosophila melanogaster is Greek again).

One interesting pattern I've noticed in mammals is that even when Linnaeus named the first genus in a group by a Latin name, usually most later names for related genera use Greek roots instead. For example, Linnaeus gave the name Mus to mice, and that is still the genus name for the house mouse, but most related genera use compounds of the Greek-derived root -mys (from μῦς), which also means "mouse." Similarly, bats for Linnaeus were Vespertilio, but there are many more compounds of the Greek root -nycteris (νυκτερίς); pigs are Sus, but compounds usually use Greek -choerus (χοῖρος) or -hys/-hyus (ὗς); weasels are Mustela but compounds usually use -gale or -galea (γαλέη); horses are Equus but compounds use -hippus (ἵππος).
