Des villageois des contreforts de l'Himalaya viennent au zoo de Lucknow pour voir véritablement à quoi ressemblent le tigre et le léopard, et pour apprendre un comportement adéquat en cas de rencontre. The Times of India, ce jour. TNN. "Know the tiger" lessons at zoo for villagers who don't know the animal.

 "It was a big animal, similar to a blue bull."

"I saw it from a distance, it was as large as a buffalo."

"I fought with a strange animal to save my cattle. I am not sure if it was a tiger or a leopard."

These are some of the responses the forest department gets from villagers who have had encounters with tigers near their habitat. In many cases, ignorant villagers end up harming the endangered animal simply because they do not know what it is. To avoid man-tiger conflict, people living in forest-villages of UP will be taken to the zoo in batches and shown what a tiger looks like.

Most of these people do not know what colour a tiger or a leopard is or which has stripes and which has spots...

L'essentiel est invisible pour les yeux. Antoine de St Exupéry.

Les baleines franches de l'Atlantique Nord (baleines des basques, Eubalaena glacialis) n'étaient plus que quelques dizaines d'individus quand elle furent officiellement protégées, en 1935. Depuis lors, leur population augmente lentement (300 au début de ce siècle, 500 aujourd'hui). Elles sont surtout observées près des zones urbaines. Or, certaines d'entre elles disparaissent pendant des années (8 ans, 14 ans...) puis réapparaissent avec un baleineau, alors que les scientifiques les croyaient mortes depuis longtemps. Leurs itinéraires et activités sont inconnus pendant ces périodes. La dynamique d'éloignement vis - à - vis des zones urbaines induit, qui plus est, l'existence d'une population additionnelle invisible et inconnue...

https://www.theatlantic.com/science/archive/2017/05/whale-moms/526494/

The Atlantic Daily, hier.  Elizabeth Preston. The mystery of off – the – grids whale moms. Some right whales disappear for years, only to reemerge in strange places with a baby.

Thick fog sat over Cape Cod Bay the morning of April 20, so the survey boat had to work by sound. Every so often, the researchers aboard cut their engine and listened for deep blows to track down surfacing right whales. By mid-afternoon, the fog had lifted, and Marilyn Marx could clearly see markings on one nearby whale that made her excited. “Big white scar!” she called down to the others from the boat’s tower. “Could be 1412!”

Just then, a baby whale popped up next to the massive female. The group on the boat let out a unanimous whoop.

Marx, a scientist at the New England Aquarium in Boston, and the others scrambled to get photographs and skin samples of the mother and calf. Earlier that month, an aerial-survey team had spotted the pair in the area, and the scientists on the water didn’t want to miss their chance to gather data. Unlike most right-whale moms, 1412 hadn’t given birth in the customary calving grounds. Researchers spot most whales in the population every year or two along the eastern coast of North America. She was last glimpsed 14 years ago—in Iceland. No one knows where she spends her time or has her babies.

The mystery mom, and other wanderers like her, stymie researchers’ efforts to monitor them. But they might offer clues that this endangered population is a little better off than it seems.

Scientists estimate that only around 500 North Atlantic right whales are alive today. For the most part, they hug the coast, says the New England Aquarium research scientist Philip Hamilton. In the winter, mothers give birth near Florida and Georgia; in the spring and summer the whales feed around New England and Canada. A network of spotters identifies whales by their unique markings and tracks their movements. At the aquarium, Hamilton curates a catalog of every known whale and its sighting history.

Some scientists have nicknamed North Atlantic right whales the “urban whales” because they live so intimately with human cities. Swimming near the coast, they get tangled in nets and struck by ships. Pollution taints their waters and noise stresses them constantly. But Hamilton estimates that a small number of the animals are what he calls “suburban whales.” They pop up now and then in the usual habitats—but otherwise they stay off the grid. “Those animals have lots of mystery about them,” Hamilton says. “We don’t know where they call home most of the time.”

Perhaps the daughters of suburban moms also swim off the beaten path.

1412 is one of those whales. “She’s been always a favorite of mine,” Hamilton says, rattling off her strange sighting history: 1984, off the coast of New Hampshire, with a calf. Eleven years later, east of Greenland. In 1997, New Hampshire again, with another calf.* 2003, Reykjavik, where an Icelandic whale-watch company got the last photo of her. The long gaps between her sightings are highly unusual. Adding to her intrigue, 1412 is covered in scars. But the scars don’t match the usual patterns from fishing lines and nets, Hamilton says; her wounds may have come from ice.

The reappearance of 1412 this year was especially exciting because of the calf swimming with her. It was a bad winter for whale babies: Only three were born at the calving grounds. In an average year there would be more like 14, Hamilton says. Then, at the end of April, there was more good news: A fifth calf appeared up north. This calf’s mother was another mysterious whale, number 1515. She hadn’t shown up since 2009 and was presumed dead. 1515 has used the calving grounds in the past, Hamilton says, but in between babies she “fully disappears.”

It’s possible that most suburban whales stray only slightly from where scientists usually look. On the other hand, one right whale in the catalog has turned up in the Azores, west of Portugal; another swam to one of the northernmost fjords of Norway. Right whales aren’t known to be very social, so Hamilton says it’s unclear what the whales sacrifice by traveling apart from the group. But they might gain more by being farther away from humans. If suburban whales aren’t where we can spot them, then by definition they must be farther from our noise, ships, and other threats.

Furthermore, right whales’ food sources along the eastern seaboard have been dramatically shifting, probably due to global warming. Whales that swim in unusual places might know about other, better places to find food, Hamilton says. During a reproductive crash in the late 1990s, he notes, at least half of right-whale babies came from suburban moms.

Calves stay with their mothers for about a year. It’s hard to track the young of off-the-grid moms after, Hamilton says, but at least some have integrated with the urban whales. Female calves, when they grow up and have their own young, tend to take those calves to the same habitats where their mothers took them. Hamilton recalls one whale mom who calved up north, then brought her female calf all the way to Florida in July, a trip that’s “unheard of” for the heat-averse whales. He suspects the mother was seizing her only chance to show her daughter the right place to have babies. Perhaps the daughters of suburban moms also swim off the beaten path.

In another six months or so, researchers at Trent University in Ontario will have genetic information from the skin samples they took from 1412 and her calf. They’ve sampled more than 300 mother-calf pairs, Hamilton says, and stumbled across something surprising in the DNA: Many of the calves weren’t fathered by any whale in the catalog. In addition to mystery moms, there seem to be mystery dads who have never been seen at all. There might even be a few dozen of them. And if there are missing males, there could be missing females, too.

The population may be larger than we think,” Hamilton says. For such a threatened species, learning that dozens more animals are living secret lives somewhere in the ocean “would be huge.”

Le Birobidjan (région autonome juive), petite entité de l'extrême orient russe (36 000 Km2) enchassée entre la région de l'Amour et le territoire de Khabarovsk, n'abrita plus aucun tigre entre les années 90 du siècle dernier et le début des années 2010. Depuis lors, un plan de réintroduction de noyaux familiaux en à l'oeuvre, à partir d'orphelins recueillis et soignés dans des centres, puis relâchés.

Avec les naissances de ce printemps, les animaux sont vraisemblablement, désormais, plus d'une dizaine.

"Svetlaya" et ses enfants. Cliché pris le 24 avril.

A trail camera at the Zhuravliny Nature Sanctuary in the Jewish Autonomous Region has captured Svetlaya the tigress with cubs. The cubs were hiding behind their mum, so it was impossible to count them. The father of the cubs is Borya, with whom Svetlaya has lived in Zhuravliny for almost two years.

 

The new addition to Borya and Svetlaya’s family is a unique case because the tigers were released into the wild after completing a rehabilitation programme. Borya and two other orphaned cubs, Kuzya and Ilona, were released in May 2014. Svetlaya was set free in June 2014. It is also worth mentioning that the predators formed a pair by themselves despite the 500 kilometres that divided them. Svetlaya and Borya met each other for the first time in October 2015. The Amur Tiger Programme, ce jour.

Selon Charles Wohlforth, l'association Sea Shepherd, en s'opposant à la chasse traditionnelle à la baleine, poursuit la conquête de l'Amérique par les Puritains d'origine européenne, et s'inscrit dans la démarche des missionnaires. Alaska Dispatch News. com, ce jour. Sea Shepherd and others attacking native whaling are allies of conquest.

L'île St Laurent, peuplée par les Yupiks, dépend de l'Alaska, mais elle est beaucoup plus proche du sud de la péninsule de Chukotka. Il y a un millénaire environ, au début de l'optimum climatique médiéval (qui donna son nom de "pays vert" au Gröenland), des rhytines de Steller vivaient encore sur cette île ( pendant qu'en Europe orientale, des tigres parcouraient les forêts alluviales du Dniepr et du Danube).

Les têtes d'un griffon et d'un dragon ont été taillées dans des rochers de granite de plus de 120 tonnes, il y a au moins 11000 ou 12000 ans, dans l'Altaï. Ces réalisations sont peut - être même encore beaucoup plus anciennes. Les blocs rocheux ont été obligatoirement déplacés et précisément positionnés avant d'être sculptés.

La population de tigres dans la principale réserve de l'Etat du Maharashtra (Inde centrale) est en forte hausse. La Pench Tiger reserve compte désormais 44 adultes (22 mâles et 22 femelles) contre 31 l'an dernier, auxquels s'ajoutent 7 tigreaux. The Times of India, ce jour. Vijay Pinjarkar, TNN.

Ceci fait suite à "Une arche, un sillage" mis en ligne le 2 avril dernier.

La baleine est au centre des représentations des anciens scandinaves, le plus souvent sous une forme terrifiante et destructrice. 

http://www.northsailing.is/news/nr/1945/icelandic-myths-and-tales-of-whales/

En Islande, parmi ces créatures surréelles, la "baleine chatte" miaule, et peut être aussi bien "bonne" que "mauvaise", la "baleine taureau" attire les vaches dans l'océan. Vers le septentrion, Zeus serait - il devenu "poisson"?

The Cat Whale. Once, the “Cat Whale” came towards a fishing boat and placed itself right next it, so the fishermen could not bring out the fishing gear any longer. They then wanted to throw spears at the whale, but the captain did not allow it, being afraid it might smash the boat with its fluke. During the night, the whale had disappeared and was never to be seen again. The fishermen said that it was safe to allow the whale to rest next to the boat, letting it “cry” just like a cat. Cat Whales were considered to be both, “good” and “evil".

The Bull Whale. The “Bull´s Whale” received it´s name due to the noise he created while blowing, which sounded like the roar of a bull. Once a cow ran into the ocean after she had heard that noise, and was never to be seen again. Near Húsavík, such whale had roared so loud that people and all of the cows living on the nearby island could hear it. The cows started to run, wanting to jump in the ocean, but fortunately, they could be stopped and rescued. Though, the cows had then to be kept inside the stable for several days. Northern ZEUS ?

Ce qui est peut être un cachalot surréel, la "baleine cheval" est présentée comme le plus grand des cétacés à dents, destructeur de navires et dévoreur de marins, accompagné de belougas qui consomment ses reliefs de repas, comme le feraient des isatis avec les ours polaires...

The Redcomb. The “Redcomb” was constantly on the look out for humans to be killed, and their boats to be destroyed. Being the biggest of all toothed whales, the people had depicted it as being a horse-whale. It could swim so fast, that it would encircle Iceland in only 48 hours. Redcombs were escorted by the white belugas, which enjoyed the leftovers of their prey.

Une autre est entièrement cuirassée d'une armure de bernacles. The barnacle whale. The “Shell Whale”, or "Barnacle Whale" was covered with seashells. It was anxious to smash the boats and ships with its fluke and flippers. Even if the whale just passed by, it would squish the boats by simply jumping on them. It was of no use to try to scare it away, because it would come back again immediately.

RESPIRATION INTERGLACIAIRE, POSSIBILITE D'UNE ÎLE. Baleines sanctuaire, protectrice, pourvoyeuse...

La plus grande de toutes est végétalisée, son corps est recouvert de bruyères, comme dans une prairie d'altitude ou une toundra. The “Ling-Back”, the biggest of all whales, looked like an island when seen from above, since it´s back was covered with lings.

Une île (illustration de Matt Kish).

Comme les "jumeaux blancs" du Japon ou les protecteurs de la Sonde ("Une arche, un sillage" mis en ligne le 2 avril dernier), la "baleine bleue" (différente de l'animal réel) protège les navires contre les baleines aux intentions hostiles. Elle va jusqu'à se faire exploser pour repousser un trop grand nombre d'assaillants. The blue protector. The "Blue whale", the big protector of the fishing boats, did scare away all the wicked whales. By encircling the boat three consecutive times, it indicated the approach of danger. It happened that the blue whale tried to chase away the “evil whales”, even if they were superior in number. Though, if there were more than three, the blue whale would explode, dragging the others till death.  

Les Norvégiens, inventeurs de l'industrie baleinière moderne, connaissent un épisode politique stupéfiant au début du XXème siècle : des paysans - pêcheurs, qui travaillent en association avec des rorquals communs (tradition qui remonte au moins au XIIIème siècle) sont à l'origine de la creation du parti travailliste, qui protège les grands cétacés entre 1904 et 1924, après une lutte politique fertile en actions directes.

Dans l'Antarctique, ceux - ci ouvrent les premières stations baleinières de l'histoire à la même époque. Solveig Jacobsen sera le premier enfant blanc né au delà du cercle polaire antarctique.

Solveig en 1916, aux côtés de son chien, à la station baleinière de Grytviken, dirigée par son père auquel elle tient la main. Elle a trois ans.

Francisco Coloane, dans son "El camino de la Ballena" dont il situe l'action en Antarctique en 1920, décrit notamment la compétition entre baleiniers norvégiens et chiliens. Georges Blond ("La grande aventure des baleines", Bibliothèque de la mer, éditions Amiot - Dumont, 1953) évoque, dans le même contexte, la figure d'"Einar Börnik" (peut être un "concentré" de plusieurs personnages réels), le harponneur qui tua 5000 baleines en 20 ans... 

En 1963, le baleinier norvégien "Durei" est coulé par un cachalot (The Courier, Brooklin, du 13 avril 2002).

Aperçu d'un monde en équilibre. Vidéo sur l'évolution du tigre et sa diversité passée (en espagnol). Courte (un peu plus de 3mn), mais intéressante et spectaculaire.

 https://www.youtube.com/watch?v=rXThARFao5c

Le tigre de Wanhsien occupa une large partie de l'Eurasie de la fin du Pliocène au Pleistocène médian, époque présumée de sa disparition. Il était légèrement plus volumineux que le tigre de Sibérie.

Le tigre de Ngandong occupait l'arc australasien, peut - être jusqu'aux abords de l'actuelle Nouvelle - Guinée. Certains individus étaient encore plus volumineux que son congénère eurasien (certains mâles pouvaient peser 470kgs).

Les cartes biocoenotiques ont été entièrement rebattues lors d'un bouleversement géoclimatique d'origine volcanique, il y a 74 000 ans, qui a mis en très grand péril les phylums félin et humain...

Un grand merci à Eduardo Santos pour sa communication gracieuse.
