Comment assurer l'essor des tigres géants au XXIème siècle? Par la préparation, aujourd'hui, de pépinières de pins de Corée, qui atteindront 60m de hauteur, et qui, tous les 3 ou 4 ans, nourriront les habitants de la taïga (de toutes espèces), chacun d'entre eux pouvant produire 70 000 fruits particulièrement roboratifs. Ainsi, des étudiants qui rêvent de changer le monde le font très concrètement. Amur Tiger Centre, ce jour.

Face au trafic des navires pétroliers et gaziers,  les baleines à bosse du nord de la Colombie Britannique renoncent à mener une vie marine. Si elles se tiennent, au début de l'été, dans les canaux périphériques du fjord de Douglas, à la fin de l'été, elles s'enfoncent au coeur du territoire des ours - esprits (ours Kermode). Animaux surdominants du secteur (déjà 700 à ce jour), leur nombre ne cesse de croître. Il s'agit bien de la recherche d'un endroit tranquille (beaucoup plus qu'une quête de nourriture). Deux cultures d'orques traditionnellement résidentes (piscivores) et nomades (prédatrices de mammifères marins) tendent à adopter un comportement similaire, et il en va de même pour des rorquals communs, tous dans la même zone. Huffington Post, hier. Eric Keen. "In British Columbia, a strange pattern in humpback whale behaviour raises the stake for conservation."

Dans la même région, hier matin, un tigre a tué Shrisagari Thakre, habitante du village de Boldha, venue ramasser des feuilles dans la forêt. Samedi dernier, un ours avait déjà tué 3 personnes et blessé 3 autres. C'est le 13ème décès dû à des attaques d'animaux sauvages dans ce district depuis le début de l'année (10 par des tigres, 3 par l'ours déjà cité). The Times of India, ce jour. TNN.

Plus au Nord, dans l'Etat d'Uttarakhand (contreforts de l'Himalaya), la découverte hier matin du corps partiellement dévoré d'Anand Singh, un forestier, montre que des léopards mangeurs d'hommes sont toujours actifs dans le secteur de la réserve de Rajaji. Dans un périmètre de 15 kms, il s'agit du 12ème mort en 3 ans, dont 4 ces 7 derniers mois. Un homme de 35 ans avait été tué et dévoré le 3 mai. Son agresseur avait été capturé. La mort d'Anand Singh implique qu'au moins un second léopard mangeur d'hommes rôde dans les parages. The Times of India, ce jour. Seema Sharma.

Ceci fait suite à "petits ruisseaux, grande rivière" mis en ligne le 12 mai dernier. La présence de la tigresse Zoluskha dans la région autonome juive constitue une véritable pompe aspirante saisonnière... Amur Tiger Programme, hier. New tiger appears in Bastak Nature reserve.

http://programmes.putin.kremlin.ru/en/tiger/news/25524

An unknown male tiger was captured by trail cameras at the Bastak Nature Reserve in the Jewish Autonomous Region. The results of regular photo monitoring showed that the adult tigress Zolushka and two males, Zavetny and Bastak, still live in the reserve. Zavetny seems to not mind that young Bastak lives in his territory, but it is yet unknown if he would be as tolerant to the new tiger. 

Experts link the “inrush” of tigers into the reserve to Zolushka, who is ready to mate and leaves markings that attract males from neighbouring areas. This also caused a fight between two tigers near the Sagdy-Bira River at the end of January. The tracks showed that one of the tigers later left for the border of the Jewish Autonomous Region and the Khabarovsk Territory. Experts believe that the appearance of a new male might complicate the situation in the local population.

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.

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).
