Uli Westphal: Elephas Anthropogenus
"After the fall of the Roman Empire, elephants virtually disappeared from Western Europe. Since there was no real knowledge of how this animal actually looked, illustrators had to rely on oral and written transmissions to morphologically reconstruct the elephant, thus reinventing an actual existing creature. This tree diagram traces the evolution of the elephant depiction throughout the middle ages up to the age of enlightenment."

"Tracking wildlife with technology in 50 maps and graphics

For thousands of years, tracking animals meant following footprints. Now satellites, drones, camera traps, cellphone networks, apps and accelerometers allow us to see the natural world like never before. Geographer James Cheshire and designer Oliver Uberti take you to the forefront of this animal-tracking revolution. Meet the scientists gathering wild data – from seals mapping the sea to baboons making decisions, from birds dodging tornadoes to jaguars taking selfies. Join the journeys of sharks, elephants, bumblebees, snowy owls and a wolf looking for love. Find an armchair, cancel your plans and go where the animals go."]

Robert Sapolsky discusses physiological effects of stress
"In addition to numerous scientific papers about stress, Sapolsky has written four popular books on the subject—Why Zebras Don't Get Ulcers, The Trouble with Testosterone, A Primate's Memoir and Monkeyluv. Many of his insights are based on his 30-year field study of wild African baboons, highly social primates that are close relatives of Homo sapiens. Each year, he and his assistants follow troops of baboons in Kenya to gather behavioral and physiological data on individual members, including blood samples, tissue biopsies and electrocardiograms.

"We've found that baboons have diseases that other social mammals generally don't have," Sapolsky said. "If you're a gazelle, you don't have a very complex emotional life, despite being a social species. But primates are just smart enough that they can think their bodies into working differently. It's not until you get to primates that you get things that look like depression."

The same may be true for elephants, whales and other highly intelligent mammals that have complex emotional lives, he added.

"The reason baboons are such good models is, like us, they don't have real stressors," he said. "If you live in a baboon troop in the Serengeti, you only have to work three hours a day for your calories, and predators don't mess with you much. What that means is you've got nine hours of free time every day to devote to generating psychological stress toward other animals in your troop. So the baboon is a wonderful model for living well enough and long enough to pay the price for all the social-stressor nonsense that they create for each other. They're just like us: They're not getting done in by predators and famines, they're getting done in by each other."

It turns out that unhealthy baboons, like unhealthy people, often have elevated resting levels of stress hormones. "Their reproductive system doesn't work as well, their wounds heal more slowly, they have elevated blood pressure and the anti-anxiety chemicals in their brain, which have a structural similarity to Valium, work differently," Sapolsky said. "So they're not in great shape."

Among the most susceptible to stress are low-ranking baboons and type A individuals. "Type A baboons are the ones who see stressors that other animals don't," Sapolsky said. "For example, having your worst rival taking a nap 100 yards away gets you agitated."

But when it comes to stress-related diseases, social isolation may play an even more significant role than social rank or personality. "Up until 15 years ago, the most striking thing we found was that, if you're a baboon, you don't want to be low ranking, because your health is going to be lousy," he explained. "But what has become far clearer, and probably took a decade's worth of data, is the recognition that protection from stress-related disease is most powerfully grounded in social connectedness, and that's far more important than rank.""

Badru’s Story: Early Warnings From Inside an Impenetrable African Forest by : Yale Environment 360
"Each year Badru Mugerwa sets 60 camera traps in Bwindi Impenetrable National Park in Uganda to monitor life in one of Africa’s most diverse forests, home to roughly half the world’s mountain gorillas. As site manager for the TEAM Network, a global web of field stations, Badru collects images and data that serve as an early warning system for the loss of biodiversity and the impact of climate change in tropical forests.

In this six-minute video, winner of the 2014 Yale Environment 360 Video Contest, Benjamin Drummond and Sara Joy Steele document the researchers' work in Bwindi's remote, mountainous landscape. For the filmmakers, just preventing their equipment from snagging on the dense understory while trying to keep up with Badru and his colleagues posed a serious challenge. But their efforts were rewarded with remarkable camera-trap images of the park's primates, elephants, giant anteaters, and leopards – striking evidence of what is at stake in Bwindi and the world's tropical forests.

As a Ugandan wildlife manager tells Drummond and Steele, “This is the only forest on earth where you find gorillas and chimpanzees feeding together. Where shall we get it again?”"

The Elephant Language
Elephants live out their long lives in an exceptionally complex social network of persistent relationships. Their communication system, or language, is similarly complex. Vision and olfaction (smell), in addition to sound, are important for elephant communication.

The video and spectrogram below show an intense greeting between two African forest elephant females, Kate and Tess.

Each rumble appears as a stack of crescent-shaped lines in the spectrogram. These are called 'harmonics' and they are exact multiples of the frequency at which the vocal folds ('cords') vibrate. At several places in this vocal exchange, the voices of the two elephants overlap. This is very typical of greetings like this.

The Elephant Listening Project is focused on acoustic communication because forest elephants are very difficult to observe visually everywhere except during their brief visits to forest clearings. However, all three species of elephant (Asian, African savannah and African forest) make calls with fundamental frequencies below the lower limit of human hearing (20 Hz), in the range called infrasound. These infrasonic calls can travel far through the environment.

We are only in the early stages of decoding this language - understanding the meaning of specific signals so that we can use these to study forest elephants and help in their conservation.

For more videos linking behaviors and different types of calls, see: EleTalk
For a more detailed discussion of the elephant language, see the Dictionary"

Fab Lab Barcelona > Fabricacion Digital Personal | ELEFab
"The concept of the design of the Ele-Fab was to create a 3D puzzle that would be numbered and assembled by the kids. In order to create this elephant, a digital mesh was downloaded from the internet and adjusted to create a triangulated self-supporting structure of 95 pieces.

Additional triangulated pieces were designed to fold in from the inside in order to provide additional bracing for the exterior triangulation. All the pieces were then numbered and lasercut in cardboard at half-scale for testing purposes.

Once the design was finalized, the elephant pieces were transported to the Montjuic Castle, where kids were introduced to laser cutting techniques through a small presentation. The kids then curiously assembled the pieces by searching for similarly numbered sides and joined them with zipties."

How Much Does A Hurricane Weigh? : Krulwich Wonders… : NPR
"In our radio broadcast on Morning Edition, Andy Heymsfield of the National Center for Atmospheric Research used elephant–sized units of water to measure hurricanes, storm clouds and little white puffies. Years ago, in a story I did on ABC, another cloud measurer used elephant units, too. But for our new cartoon, Odd Todd and I switched to blue whales. Blue whales are bigger, which we thought would make the lesson more impressive. Either way, though, hurricanes are humongous."

[Entertainment, but there is a part of me that just wants the amount of water involved to compared to a well-know body of water.]

Can a 4-year-old paint like Pollock? - By Mia Fineman - Slate Magazine
"For those who believe painting must be about something more than just color&gesture—abstract paintings by children&animals provide...proof that modern art is indeed a hoax. But [they] profoundly miss the point of the art they're trying to debunk."
