Sharks can be trained like dolphins to feed from keepers, roll over and enjoy cuddles, according to new research.

In experiments carried out in the US some varieties of shark allowed themselves to be picked from the water and cuddled.

Keepers at the UK's Sea Life Centres will now use the training techniques in the hope that they will end up with hundreds of trained sharks.

The experts at the aquariums are to begin a period of intensive tuition by using coloured boards and sounds to train the sharks in a similar way to that used by the scientist Ivan Pavlov in training dogs.

It will mean that feeding becomes easier because each shark in a tank will know when it is their turn to feed.

The Sea Life centres have many different types of shark and within just three months the brightest ones should be responding to commands.

Sharks learn the signals then, when they see or hear them, they approach the keeper who holds a "target stick".

The sharks then rub their noses against the stick and wait until they are fed.

No one had attempted to train sharks in this way before, but it could now teach experts a great deal about the creatures.

Carey Duckhouse, of Sea Life, said: "The US team has shown that many varieties of sharks can quickly learn to respond to a combination of audible and visual signals.

"A shark answers its own sound and colour signal by putting its nose on a target-stick held by the trainer, and keeping it there until it receives food.

"Some species, such as zebra sharks, will even roll over to have their tummies scratched or allow themselves to be lifted from the water without any kind of struggle.

"The implications for improving shark welfare are enormous. It means when we have to move them we can get the sharks to swim to a certain spot rather than have to chase them around."

The once-common jaguar has become a rare sight in North America, thanks to hunting and habitat fragmentation.

Now two were spotted in exceedingly rare and unrelated events this month.

The Arizona Game and Fish Department caught and collared a wild jaguar in Arizona for the first time, officials said Thursday. While a handful of the big cats have been photographed by automatic cameras in recent years, the satellite tracking collar will now help biologists learn more about this animal's range.

..
In 1997, a team was established in Arizona and New Mexico to protect and conserve the species. The Jaguar Conservation Team (JCT) began working with Mexico two years later, recognizing that the presence of jaguars in the United States depends on the conservation of the species in Mexico.

Interestingly, the project set up to do all this is funded by Arizona Lottery ticket sales.

..
"The photographs provide information about new recording sites, and allow us to deduce that the area where the animal was observed may be a corridor connecting jaguar populations," Monroy-Vilchis said.
..
Jaguars can live in several types of forest, grassland and dry habitat. They prey on a variety of animals, including fish, birds and reptiles. The largest contiguous area of habitat now remaining for jaguars centers in the Amazon Basin.

About global warming, Thầy recounted to Times Magazine the story about the couple who ate their son’s flesh – the story told by the Buddha in the Son’s Flesh Sutra. This couple, with their little child, on their way seeking asylum had to cross the desert. Due to a lack of geographical knowledge, they ran out of food, while they were only half way through the desert. They realized that all three of them would die in the desert, and they had no hope to get to the country on the other end of the desert to seek asylum. Finally, they made the decision to kill their little son. Each day they ate a small morsel of his flesh, in order to have enough energy to move on, and they carried the rest of their son’s flesh on their shoulders, so that it could continue to dry in the sun. Each time when they finished eating a morsel of their son’s flesh, the couple looked at each other and asked: “Where is our beloved child now?” Having told this tragic story, the Buddha looked at the monks and asked: “Do you think that this couple was happy to eat their son’s flesh?” “No, World Honored One. The couple suffered when they had to eat their son’s flesh,” the monks answered. The Buddha taught: “Dear friends, we have to practice eating in such a way that we can retain compassion in our hearts. We have to eat in mindfulness. If not, we may be eating the flesh of our own children.”

UNESCO reported that each day about 40,000 children die because of hunger or lack of nutrition. Meanwhile, corn and wheat are largely grown to feed livestock (cows, pigs, chickens, etc.) or to produce alcohol. Over 80 percent of corn and over 95 percent of oats produced in the United States are for feeding livestock. The world’s cattle alone consume a quantity of food equivalent to the caloric needs of 8.7 billion people, more than the entire human population on earth.

Eating meat and drinking alcohol with mindfulness, we will realize that we are eating the flesh of our own children.

In 2005, the United Nations Food and Agriculture Organization (FAO) began an in-depth assessment of the various significant impacts of the world’s livestock sector on the environment. Its report, titled Livestock’s Long Shadow: Environmental Issues and Options, was released on November 29th 2006. Henning Steinfeld, chief of FAO’s Livestock Information and Policy Branch and senior of the report, in the executive summary, asserts that: “The livestock sector emerges as one of the top two or three most significant contributors to the most serious environmental problems, at every scale from local to global. The findings of this report suggest that it should be a major policy when dealing with problems of land degradation, climate change, air pollution, water shortage, water pollution and loss of biodiversity. Livestock’s contribution to environmental problems is on a massive scale and its potential contribution to their solution is equally large. The impact is so significant that it needs to be addressed with urgency”

Land degradation: Presently, livestock production accounts for 70 percent of all agriculture land and 30 percent of the land surface of the planet. Forests are cleared to create new pastures, and it is a major driver of deforestation. For example, in Latin America some 70 percent of former forests in the Amazon have been turned over to grazing . From these figures, we can see that the livestock business has destroyed hundreds of millions acres of forest all over the world to grow crops and to create pastureland for farm animals. Moreover, when the forests are destroyed, enormous amounts of carbon dioxide stored in trees are released into the atmosphere.

Climate change: The livestock sector has major impacts on the atmosphere and climate. It is responsible for “18 percent of greenhouse gas emissions measured in carbon dioxide equivalent, which is a higher share than transport.” This means that raising animals for food generates more greenhouse gases than all the cars and trucks in the world combined. The livestock sector accounts for 9 percent of anthropogenic carbon dioxide emissions. It also emits 37 percent of anthropogenic methane, most of that from enteric fermentation by ruminants. This is an enormous amount, because every pound of methane is twenty three times as effective as carbon dioxide is at trapping heat in our atmosphere (23 times the global warming potential [GWP] of carbon dioxide). The meat, egg, and dairy industries are also responsible for the emission of 65 percent of anthropogenic nitrous oxide, most of that from manure. Nitrous oxide is about 300 times more potent as a global warming gas than carbon dioxide (296 times the GWP of carbon dioxide). It is also responsible for about two-third (64 percent) of anthropogenic ammonia emissions, which contribute largely to acid rain and accidification of ecosystem .

Water scarcity and water pollution: More than half of all the water consumed in the U.S. is used to raise animals for food. It requires 2,500 gallons of water to produce a pound of meat. Meanwhile, it takes only 25 gallons of water to produce a pound of grain. Livestock in the United States produce an enormous amount of animal excrement, 130 times more than human excrement; each second the animals release 97,000 pounds of feces. “Most of the water used for livestock drinking and servicing returns to the environment in the form of manure and wastewater. Livestock excreta contain a considerable amount of nutrients [nitrogen, phosphorus, potassium], drug residues, heavy metals and pathogens” (page 136)1. These waste products enter streams and rivers, polluting water sources and causing disease outbreaks that affect all species.

Just as the Buddha cautioned us, we are eating the flesh of our children and grandchildren. We are eating the flesh of our mothers and our fathers. We are eating our own planet earth. The Son’s Flesh Sutra needs to be available for the whole human race to learn and practice.

The U.N.’s recommendation is clear: “The environment impact per unit of livestock production must be cut by half, just to avoid increasing the level of damage beyond its present level,” . We need to reduce at least 50 percent of the meat industry products, and that we must consume 50 percent less meat. The U.N. also reports that even if cattle-rearing is reduced by 50 percent, we still need to use new technology to help the rest of cattle-rearing create less pollution, such as choosing animal diets that can reduce enteric fermentation and consequent methane emissions, etc. Urgent action must be taken at the individual and collective levels. As a spiritual family and a human family, we can all help avert global warming with the practice of mindful eating. Going vegetarian may be the most effective way to fight global warming.

Buddhist practitioners have practiced vegeterianism over the last 2000 years. We are vegeterian with the intention to nourish our compassion towards the animals. Now we also know that we eat vegeterian in order to protect the earth, preventing the greenhouse effect from causing her serious and irreversible damage. In the near future, when the greenhouse effect becomes severe, all species will suffer. Millions of people will die, and sea levels will rise and flood cities and land. Many life-threatening diseases will result, and all species will suffer the consequences.

Both monastic practitioners and lay people practice vegeterianism. Even though the number of lay practitioners who are 100 percent vegeterian is not as many as monastic practitioners, but they practice eating vegeterian meals either for 4 days or 10 days each month. Thầy believes that it is not so difficult to stop eating meat, when we know that we are saving the planet by doing so. Lay communities should be courageous and give rise to the commitment to be vegetarian, at least 15 days each month. If we can do that, we will feel a sense of well-being. We will have peace, joy, and happiness right from the moment we make this vow and commitment. During the retreats organized in the United States this year, many American Buddhist practitioners have made the commitment to stop eating meat or to eat 50 percent less meat. This is a result of their awakening, after they have listened to the Dharma talks on the greenhouse effect. Let us take care of our Mother Earth. Let us take care of all species, including our children and grandchildren. We only need to be vegeterian, and we can already save the earth. Being vegeterian here also means that we do not consume dairy and egg products, because they are products of the meat industry. If we stop consuming, they will stop producing. Only collective awakening can create enough determination for action.

Taken off the coast of Mexico's Holbox Island by amateur photographer Sandra Critelli, this breathtaking picture captures the migration of thousands of rays as they follow the clockwise current from Mexico's Yucatan peninsula to western Florida.

Measuring up to 6ft 6in across, poisonous golden cow-nose rays migrate in groups - or 'fevers' - of up to 10,000 as they glide their way silently towards their summer feeding grounds.

These cow-nose rays (Rhinoptera bonasus) have distinctive, highdomed heads, giving them a curiously bovine appearance.

But even equipped with this powerful poisonous stinger, cow-nose stingrays are shy and non-threatening in large 'fevers'. Even when isolated, they will attack only when cornered or threatened.

Unlike other stingrays, they rarely rest on the seabed (where unsuspecting humans can step on them) and prefer to be on the move.

They migrate long distances, and can be found as far south as the Caribbean and as far north as New England.

They use their extended pectoral fins to swim, and often turn upside down, curling their fin tips above the surface of the water - leaving terrified swimmers convinced that they have seen a shark. :)

Their flexible fins also come in handy when rustling up food. By flapping them rapidly over the seabed, they stir up sand and reveal crabs, shellfish and oysters, which they then feed on using their powerful, grinding teeth.

Their particular fondness for shellfish has made them public enemy number one with oyster fishermen.

But despite this, their numbers are exploding, thanks in part to rising sea temperatures. They mate every winter, and females produce a litter of five to ten young.

Space may be the final frontier, but scientists who recently discovered a hidden forest in Mozambique show the uncharted can still be under our noses. BirdLife were part of a team of scientists who used Google Earth to identify a remote patch of pristine forest. An expedition to the site discovered new species of butterfly and snake, along with seven Globally Threatened birds.

The team were browsing Google Earth – freely available software providing global satellite photography – to search for potential wildlife hotspots. A nearby road provided the first glimpses of a wooded mountain topped by bare rock. However, only by using Google Earth could the scientists observe the extent of woodland on the other side of the peak. This was later discovered to be the locally known, but unmapped, Mount Mabu.

The research team, writing in the science journal PLoS One, said they repeatedly observed a female dolphin herding cuttlefish out of algal weed and onto a clear, sandy patch of seafloor.

The dolphin, then pinned the cuttlefish with its snout while standing on its head, before killing it instantly with a rapid downward thrust and "loud click" audible to divers as the hard cuttlebone broke.

The dolphin then lifted the body up and beat it with her nose to drain the toxic black ink that cuttlefish squirt into the water to defend themselves when attacked.

Next the prey was taken back to the seafloor, where the dolphin scraped it along the sand to strip out the cuttlebone, making the cuttlefish soft for eating.

"It's a sign of how well their brains are developed. It's a pretty clever way to get pure calamari without all the horrible bits," Mark Norman, the curator of molluscs at Museum Victoria.

A separate 2005 study provided the first sign dolphins may be capable of group learning and using tools, with a mother seen teaching her daughters to break off sea sponges and wear them as protection while scouring the seafloor in Western Australia.
