After our planet’s climate drastically changes, the wildlife of today will exist in cloned form in tomorrow’s zoos, Inter Press Service reports:

Brazilian scientists are attempting to clone animals in danger of extinction, like the jaguar and maned wolf, although the potential impact on the conservation of these threatened species is still not clear.
The cloning initiative is being undertaken by the Brasilia Zoological Garden in partnership with the Brazilian government’s agricultural research agency, EMBRAPA, and is now in its second phase. “We already have 420 germplasm samples stored in our bank and are going to continue collecting,” [said] EMBRAPA researcher Carlos Frederico Martins.
Eight animals have been chosen, including the maned wolf (Chrysocyon brachyurus), the jaguar (Panthera onca) and the black lion tamarin (Leontopithecus chrysopygus). The bank has also been stocked with germplasm from the bush dog (Speothos venaticus), coati (genus Nasua), collared anteater (Tamandua tetradactyla), gray brocket deer (Mazama gouazoubira) and bison (genus Bison).
Animals have distinct personality types, the Telegraph reveals

In a new study of African elephants, researchers have identified four distinct characters that are prevalent with a herd – the leaders, the gentle giants, the playful rogues and the reliable plodders. Each of the types has developed to help the giant mammals survive in their harsh environment and are almost unique in the animal kingdom, according to the scientists.
Professor Lee and her colleague Cynthia Moss studied a herd of elephants in the Amboseli National Park in Kenya known as the EB family – famous for their matriarch Echo before she died in 2009. Using data collected over 38 years of watching this group, the researchers analysed them for 26 types of behaviour and found four personality traits tended to come to the fore.
The strongest personality to emerge was that of the leader. The researchers looked for those elephants that tended to influence the movements and direction of the group.
The monkey gave the forces of human society a good run for their money, remaining uncaught for two years. Over that time, it had a Facebook page and bit a random woman — in other words, it lived as a typical St. Petersburg resident. Via CBS Tampa:
The wild monkey that was on the lam in St. Petersburg for two years has finally been captured. Authorities say a wildlife official shot the monkey with a tranquilizer dart Wednesday.
The monkey eluded capture for years as it roamed neighborhoods in St. Petersburg. It even has a Facebook page and most recently bit a woman, causing trappers to ramp up their efforts to capture him.
...in a study published in Nature, researchers at Royal Holloway, University of London, in Egham, UK, show that low-level exposure to a combination of two pesticides is more harmful to bumblebee colonies than either pesticide on its own. The results suggest that current methods for regulating pesticides are inadequate because they consider only lethal doses of single pesticides. As ecologist Nigel Raine explains in the video, low doses of pesticides have subtle effects on individual bees and can seriously harm colonies. He hopes that his work will feed into consultations on pesticide regulations that are happening now in Europe.Read more.
Does this portend a future war between apes and humanity? Local media in the Democratic Republic of the Congo are interpreting a spate of chimp violence perpetrated against people as motivated by revenge. Via New Scientist:

Habitat loss may be to blame for an apparent spate of violent attacks by chimpanzees on humans in the war-torn eastern region of the Democratic Republic of the Congo.
Mistrust of chimpanzees has been heightened by local media reports, which suggest that as many as 10 people have been killed and 17 injured by chimps, in acts that were reported as “revenge attacks” for people encroaching on their territory.
Klaus Zuberbuhler, a psychologist at the University of St Andrews in Fife, UK, and scientific director of the Budongo Conservation Field Station in Uganda, says restricting the chimps’ habitat can certainly affect their behaviour, though it is debatable whether the chimps’ aggression towards humans is a form of revenge.
The Orlando Sentinel reports on a monstrous find:
In Pompano Beach, Gino Covacci noticed a strange ball-like object at the high tide line. He kicked it over and found himself staring at the biggest eyeball he had ever seen. “It was very, very fresh,” he said Thursday. “It was still bleeding when I put it in the plastic bag.”
He notified a police officer, who gave him the phone number for the Florida Fish and Wildlife Conservation Commission. It will be preserved in formalin, a mixture of formaldehyde and water, before being sent for analysis to the Florida Fish and Wildlife Research Institute in St. Petersburg, said Carli Segelson, spokeswoman for the wildlife commission.
No one could say immediately what species the giant eye came from. Charles Messing, a professor at Nova Southeastern University’s Oceanographic Center, said he couldn’t rule out a giant squid.
Ever wondered if we are not alone in the universe?
As this truly nerdgasmic crash-course by Robert A. Freitas Jr speculates, the scope for alien life could be positively astronomical. Via xenology.info:

Xenology is the study of all aspects of life, intelligence, and civilization indigenous to environments other than Earth. Over the last three decades xenology has advanced rapidly on many fronts. Biochemists have studied the origin of life on this planet, knowing that if they can duplicate the major early steps of “abiogenesis” in the laboratory then the evolution of alien life is a very likely – maybe inevitable – event. NASA biologists have spent much time developing sophisticated life detection instruments such as the miniature biochemical automated test laboratories carried to Mars by Viking in 1976. There is growing interest in SETI, the Search for Extraterrestrial Intelligence, in which radio scientists look for powerful transmissions or leakage radiation from advanced extraterrestrial supercivilizations.
Barely-alive creatures, such as the slime mold at right, are able to produce “memories” — they just store them in their physical surroundings rather than a brain, Ars Technica has the latest news on the secret lives of simple beings:

Is it possible to know where you’ve been when you don’t have a brain? Depending on your definition of “know,” the answer may be yes. Researchers have shown that the slime mold, an organism without anything that resembles a nervous system (or, for that matter, individual cells), is capable of impressive feats of navigation. It can even link food sources in optimally spaced networks. Now, researchers have shown it’s capable of filling its environment with indications of where it has already searched for food, allowing it to “remember” its past efforts and focus its attention on routes it hasn’t explored.
In the course of studying the slime mold, some researchers noticed that the slime mold would avoid any areas covered in slime.
