“If facts are the seeds that later produce knowledge and wisdom, then the emotions and the impressions of the senses are the fertile soil in which the seeds must grow.”
Rachel Carson | Marine Biologist

FYI: Here’s a link to the Intergovernmental Panel on Climate Change (IPCC) 2021 Sixth Assessment Report on how it’s going: not so good!

You can read five important findings from the report here.

As we’re witnessing on a daily basis, the effects of climate breakdown are absolutely heartrending. Although it’s difficult to remain hopeful given the additional uncertainty related to the pandemic, don’t despair. If we act now, there’s still time to save our beautiful, life-sustaining home from the worst impacts of climate change.

Our immense gratitude to the fact-finding, seed-planting scientists at the IPCC for persevering and fighting the good fight—for people, wildlife, and the planet.

Here Be Leafy Seadragons

1-minute read

Just when we thought we’d discovered every wild and wondrous creature that occupies Australian waters, another unique specimen drifts out of the seagrass and onto our radar. Despite its moniker, the leafy seadragon (Phycodurus eques) is no moat-dwelling flame thrower. In fact, it’s not a dragon at all, or even a reptile, but a uniquely beautiful species of fish with frond-like appendages that extend from rings of bony armor encircling its body.

The leafy seadragon’s fishy foliage serves as camouflage that helps the marine animal hide from both predators and prey in the reefs of its southwestern coastal habitat. While the seadragon may have a delicate appearance, don’t let those frills fool you. The voracious carnivore is a crustacean ambush artist, using the suction power of its tubular snout to capture vast quantities of tiny mysid shrimp.

The fish species most likely to be mistaken for underwater escarole has another highly distinctive characteristic: male leafy seadragons pitch in with pregnancy in a big way—they carry and brood eggs. Female seadragons transfer up to 250 eggs to their mate for eight weeks of safe-keeping until they hatch. Some scientists believe that females pass off eggs to papa to hide soon-to-be seadragons from predators—crafty!

Until recently, there were only two known species of seadragons, the leafy and the common (Phyllopteryx taeniolatus). In 2015, for the first time in 150 years, a new seadragon was discovered in waters off the coast of Western Australia, Phyllopteryx dewysea, a.k.a. the Ruby Seadragon. The brilliantly colored, crimson fish is not quite as elegant as its leafy cousin, but it’s splendid just the same.

Researchers think that we’ve only identified 1.6 million species out of an estimated 8.7 million globally. Now that we’re plus one fancy red seadragon, there are 7,099,999 species to go, give or take. That’s a lot of living things to factor into the healthy functioning of our planet. We’d better get busy!

If you’d like to read a lyrical ode to one of the world’s most ornate ocean dwellers, you can get free access to Miho Nonaka’s poem The Leafy Seadragon, through JSTOR.

Traveling Wildebeest Alert

1.5-minute read

One of the most spectacular events in the natural world is taking place now in the African Serengeti—the awe-inspiring, seasonal wildebeest migration. In late spring through fall, up to 1.5 million wildebeest and thousands of zebra and Thomson’s gazelles embark on the long trek from the treeless plains of the southern Serengeti in Tanzania, north to the savannas and woodlands of Kenya.

Navigating Mara River rapids and dodging the hungry lions, cheetahs, and hyenas that trail the herd is no small feat, so what motivates these high plains drifters to travel so far in such massive numbers? Survival.

Like many migrating species, wildebeests are on a mission to find food. These bearded relatives of antelopes can weigh up to 600 muscle-packed pounds. Maintaining almost a billion pounds of wildebeest-i-ness across the herd requires a tremendous amount of grass and water. When the dry season begins in May and food and water are in short supply, wildebeests head west and north, following a route determined by rainfall, grass growth, and access to prime grazing real estate. In early winter, they complete the 300-mile migration loop, tracking the rain and grass back down to the southern plains. Every February, approximately 8,000 calves a day are born in transit and are up on their hooves toddling along with the herd in just three hours—the great migration and life cycle of the wildebeest continues uninterrupted.

The remarkable journey of these African ungulates has now inspired scientists to create algorithms that mimic the highly efficient swarm-like movement of the herd, which instinctually finds the shortest route to the greenest pastures. Intelligent algorithms based on these natural patterns of wildebeest herd migration could be used in cutting-edge applications ranging from unmanned vehicles and planetary mapping to nanobots that can target and destroy cancer cells—because nature is the most intelligent system of all.

Wherever you are in the world, you can keep tabs on the amazing traveling wildebeests courtesy of HerdTracker. Compared to the congestion of mega-migration, this summer’s bumper-to-bumper beach-bound traffic doesn’t seem so bad after all…

Fireflies That Blink in Sync | New Tree Equity Scores

1-minute read

From A Place Made for We, Favorite World Press

Then each tiny firefly
said hi-hello to the night,
blinking and flashing
its very own tiny light.

Witnessing the luminous dance of blinking, flashing fireflies is one of the quiet delights of summer. Their seasonal light show is so utterly soul-soothing, it’s easy to imagine that they blink for our benefit. We know that these mesmerizing glow dispensers use flashes of light for bug-to-bug communication, but why do some species of male fireflies in large swarms coordinate their flashing and blink in sync?

According to a recent study, it appears that flashing in unison is the bioluminescent language of cooperative courtship. Male fireflies communicate using distinct flash patterns while flying, and females signal back from the ground “message received”. In large swarms of hundreds or thousands of male fireflies, random blinking and flashing could make it overwhelming for lady bugs to visually track and communicate with a specific light pilot. Scientists from the University of Connecticut believe that when groups of male Photinus carolinus fireflies blink in sync, it gives female fireflies a flash-free window to signal their interest and selectively respond to the bug of their choosing. Yes, it’s good to glow—and for some species of fireflies, when it comes to courtship, it’s better to glow together and give a girl some uninterrupted time to blink back.

Got enough trees?

Back in April, we promised to give you an update on United States tree equity scores, and here it is. The new Tree Equity Score tool developed by our partner @AmericanForests gives scores for all 486 urbanized areas of the U.S. and their 150,000 neighborhoods. Each score is an indicator of how close the city is to achieving Tree Equity—ensuring that all, not just some, people can experience the many health, economic, and climate benefits that trees provide. A zero-to-100-point system makes it easy to understand how a community fares. With the knowledge the score provides, community leaders, tree advocates, and concerned citizens can address climate change and public health through the lens of social equity. Visit TreeEquityScore.org to see how your neighborhood stacks up.

We leave you with a gentle reminder that for every print or e-book that you purchase from the FWP series, Frankie and Peaches: Tales of Total Kindness, we’ll plant one wildlands tree in a place where it’s needed most to help cool, clean, and green our home planet. Thanks for reading with us!

Bird’s Eye Compass

1-minute read

Oh, the places they’ll go…

Every spring and autumn, one in five birds travel the byways and flyways of our planet between northern breeding grounds and southern winter sanctuaries. Some species migrate astonishing distances nonstop—no layovers, no in-flight movies—like the bar-tailed godwit, which flies 7,000 miles between Alaska and New Zealand, in just seven days.

So how do nature’s long-distance frequent fliers choose the best possible migration route and stay on course to reach their destination? Send over the video if we’re wrong, but we’re pretty sure that no one has ever seen a bird consulting a sat-nav app with an intensely focused look on its feathered little face. Through evolutionary adaptation, avian navigators have developed a special retinal flight guidance mechanism that helps them to perceive altitude and direction. To locate where they need to go to survive takes no more effort than the blink of an eye.

According to new research in Nature, migratory songbirds like the European robin have photosensitive proteins in the retina of their eyes that get activated by light and function as a compass that follows directional information from the Earth’s magnetic field. The birds’ brains automatically interpret the magnetic signals that guide them north to food resources and safe nesting grounds in the spring and south to warmer habitats in the fall. Because she’s smart like that, Mother Nature has equipped our feathered friends with precisely what they need to successfully manage life-sustaining comings and goings.

FYI – U.S. Bird Health Bulletin: Songbirds in the Mid-Atlantic and Southeastern states are currently facing an unknown disease epidemic. Until wildlife researchers can determine the origins, the Audubon Society has up-to-date information and precautionary recommendations to prevent the spread of disease on your patch, how to report sightings and symptoms, and how to handle stricken birds. The pathogen is most common in young Blue Jays, European Starlings, Common Grackles, and American robins, so keep your eyes peeled out there for birds with vision problems, eye swelling, and neurological symptoms.

On a cheerier note, if at long last you’re planning on hitting the flyways and highways to do a bit of roaming of your own this year, whether you’re an old-school map-o-philiac or a sat-nav nomad, wishing you safe and very happy travels.

Fishy Antifreeze

1-minute read

It’s officially summer in the northern hemisphere. With record-breaking high temperatures already being recorded in the U.S., Canada, parts of Europe, and the Arctic, it looks like 2021 is going to be another climate change-intensified scorcher.

If you’re in need of a way to keep cool—really cool—how about a little cold water swimming? And what could be more refreshingly chilling than a dip in a polar sea? Well, as tempting as that may seem when the thermometer reads 116°F, unlike polar fishes, we gill-free types are just not equipped to last long in cold water. So what do our piscine pals have that we don’t to help them survive frigid marine temperatures? Bodies fortified with antifreeze.

To manage the challenges of a life lived in icy seas, Arctic and Antarctic fish species that aren’t able to migrate to warmer waters evolved with antifreeze proteins in their blood and body tissues. These protective proteins lower the freezing point of polar fishes to below water temperature. When they come into contact with ice crystals either on their skin or gills or through eating or drinking, the antifreeze binds to the ice to prevent the scaly swimmers from turning into fish-icles. Now, how cool is that?

If you’d like to learn more about which animals have adapted to life in the coldest environment on the planet, the New Zealand government has created a splendidly informative poster of the wildlife occupying the world’s largest marine protected area in Antarctica’s Ross Sea.

And if you’re keen to swim with fishes of the non-polar variety this summer, courtesy of The Guardian, scientist Heather Massey has some tips on how to avoid hypothermia while paddling in open waters.

Fishy business aside, just a reminder that extreme heat, like extreme cold, can be life-threatening. If you’re suffering through triple-digit temperatures and can’t make it to a pool or the beach, Google the location of your nearest cooling center and head on over. For tips on how to manage a heat wave without air conditioning, check out this list from MedicineNet. Keep cool. Stay safe.

The Prophecy of the Manatee

2.5-minute read

What does the manatee, Florida’s beloved native marine mammal, have to teach us about the importance of maintaining healthy coastal ecosystems? As recent environmental events indicate, quite a lot. A keystone species, the gentle, slow-moving occupants of the Sunshine State’s rivers, marshes, and lagoons are sensitive to environmental stressors that impact the normal functioning of their underwater world. Although manatees have few natural enemies, harmful changes in water quality have become a matter of life and death for the iconic animals—alerting us to the fragility of marine ecosystems.

Manatees, a.k.a sea cows, need two things to stay comfortably in the swim: access to warm water (at least 68°F) and a whole lot of vegetation to eat. The 1,000-pound animals can consume up to 10% of their body weight a day in plant matter, primarily seagrass. Because manatees don’t have blubber to keep them warm like whales and dolphins, the colder the water, the more calories they need to survive. The seagrass that manatees depend on for the bulk of their diet, in turn, depends on sunlight for photosynthesis.

As reported in Science, 761 manatees wintering in one Florida lagoon died of starvation in 2021 due to a shortage of seagrass. Because massive algal blooms resulting from excess nitrogen and phosphorous in the water prevented sunlight from reaching carbon-storing seagrass beds, the plants that support manatees, as well as sea turtles, fish, crustaceans, and mollusks, failed to reproduce. Although Florida manatee numbers have doubled from 3300 in 2001 to close to 7000 in 2021 thanks to protective legislation, last winter’s die-off represents a gut-wrenching 10% loss of the marine mammal’s population.

In addition to struggling to survive the algal blooms that diminish life-supporting seagrass, manatees, and other marine life, are facing the environmental effects of toxic red tides that are increasing in size and duration due to rising ocean temperatures. Between 2017 and 2018, an estimated 200 manatees died from ingesting and inhaling the neurotoxic algae from a year-long red tide event.

Despite the manatee’s status as a protected species, as with many living creatures, its capacity to adapt to adverse environmental and climate impacts is limited. The fate of the manatee and other marine animals rests on protecting and restoring life-supporting habitat. Changes to the population and well-being of the silent marine sentinels speak volumes about the health of coastal ecosystems and marine biologists and conservationists are paying close attention. They’re developing strategies to provide manatees with adequate food supplies and warm-water sanctuaries when temperatures drop and promoting policies that will help to improve water quality year-round in a rapidly warming world.

To find out how you can become a citizen scientist and help make coastal ecosystems user-friendly for the magnificent manatee and other aquatic creatures, check out this fact-sheet from the University of Florida, which includes tips on how to reduce nutrient runoff and the next right thing to do if you come across a manatee in distress.

Reducing Emissions. Increasing Hugs.

It’s Hug a Climate Scientist Day!

Emissions are still rising, and climate scientists still need hugging. That’s the bad news. The good news is, thanks to breakthroughs in biotechnology, actual hugs are making a comeback. So, we’d like to extend a major squeeze of gratitude to COVID scientists as well. Oh, and while we’re at it, thanks very much to all of the ecologists, biologists, environmental chemists, and atmospheric, geo, and social scientists toiling away every day on behalf of people, wildlife, and the planet. Hugs all around, you dedicated science brainiacs—where would the world be without you! And for anyone else in need: ((())). Plus a booster: ((())).

One more thing, speaking of dedicated people working to save the planet and all of its inhabitants, we’d like to share a beautiful and important short film (2:20 minutes) from the conservation NGO Big Life Foundation. Talk about hug magnets!

Zebras: Snazzy-Suited Insect Repellers

1.5-minute read

It would be understandable if the zebra’s fellow savanna dwellers experienced pelt envy. The wild horses’ intricate black and white coat patterning is an extraordinary sight to behold. According to researchers at the University of California at Davis, there is more to the snazzy fur of the African equine than meets the eye. After a century of stripe speculation, scientists studying how differences in color and pattern help species adapt to their natural environment have concluded that the zebra’s markings aren’t just good-looking—they’re functional, signaling pesky biting flies to bug off.

So how do zebra stripes repel insects? As it turns out, dreaded blood-sucking, disease-carrying tsetse, stable, and horse flies are fairly picky when it comes to landing sites. They are far less likely to land on black and white striped surfaces than either all white or all black surfaces. And the greater the number and the narrower the stripes, the fewer the insect attacks. Researchers discovered that zebras in regions of Africa with more flies had more and thinner stripes, especially on the vulnerable face and legs where flies bite while the animals graze.

You may be wondering why zebras, in particular, evolved to develop insect-repelling markings. Biologists believe that because zebras have shorter and thinner fur than many other horse species, nature may have equipped the African equine with the extra protection of stripes to help increase its odds of survival on the savannas.

Even with built-in bug protection, zebras will need ongoing assistance from their friends to keep prettifying the planet. There are currently three species of stripey-suited wild horses roaming the African continent: the plains, mountain, and endangered Grevy’s zebras. As a result of habitat loss, poaching, disease, competition for food, and lack of access to water, Grevy’s populations have declined from 15,000 in the 1970s to only 3,000 across Kenya and Ethiopia. You can find out how conservationists are working to prevent the extinction of one of Africa’s largest remaining land animals and how you can pitch in to help at Grevy’s Zebra Trust and Ol Pejeta Conservancy.

What else this week? June 4th and 5th, 2021, kick off the Virtual Launch Gala for the UN Decade on Ecosystem Restoration—a global rallying cry to heal the planet. Can we get a determined woohoo for getting out there to reimagine, restore, and recreate healthy ecosystems? Generation restoration—heck yeah!

And on the local-to-FWP front, for the very first time, Cornell University scientists have recorded humpbacks singing in the waters off New York City. Have a listen to their haunting whale songs—goosebumps! Happy to have you, big fellas—be careful out there!
