Prehistoric lizard surprises with fish tail

Until now it was thought havøglene had fish-like, but with long narrow body without caudal fin, and they made their way into the water by meander forward, like an eel. Now scientists might reconsider sight.

Tiger Genome Sequenced, Shows Big Cats Evolved to Kill

The first sequenced tiger genome shows that big cats evolved to kill.

Genes for strong muscle fibers and for meat-eating appear narrowly shared, researchers reported, among species as distinct as the African lion and Asia's snow leopard.
Tiger
Scientists mapped the genes of the endangered Siberian tiger (or Amur tiger), both to understand the genes that make big cat species distinct from one another and to aid efforts to preserve genetic diversity in wild tiger populations.

Why fish don't need to be schooled in the art of swimming

How do fish swim in schools, effortlessly coordinating their every move? The answer appears to be ingrained in their genes.
fishes
The genetic basis underlying the complex, social behavior of schooling is revealed in two studies published Sept. 12 in the journal Current Biology. The studies suggest that schooling is not a learned behavior, and instead show it relies on several regions of the fish genome.

News in Brief: Mice lose cat fear for good after infection

Mice may permanently shed a fear of felines when infected with a parasite. The effects linger long after the parasites disappear, a study shows.
The protozoan parasite Toxoplasma gondii can infect most mammals, including humans (SN: 1/26/13, p. 24). But the parasite can reproduce only in the feline gut, so cats need to eat animals infected with T. gondii to keep the parasite generations going.

New rat genus discovered in the birthplace of the theory of evolution

New rat genus A prominent tuft of spiny hair on the back, a white tail tip and three pairs of teats represent the unique set of characteristics describing a new genus of rat which has been discovered in the Moluccan province of Indonesia. This region had a profound influence on the British Naturalist Alfred Russell Wallace who independently developed the theory of evolution alongside Charles Darwin. The international team of zoologists was led by the Museum Zoologicum Bogoriense in Indonesia and the Center for Macroecology, Evolution and Climate at the University of Copenhagen

Conservationists deploy net-flinging cannons, GPS devices to aid restoration of endangered bird

To save one critically endangered bird population, a group of researchers are bringing in the big guns—literally. The researchers deployed a trio of cannons into areas of Cape Cod, Massachusetts, where populations of the red knot, a robin-sized bird species, are roosting and fire nets from the cannons to trap the birds in order to collect feather samples and outfit the birds with geo-locator devices. By tracking the birds via the devices, the researchers hope to gather clues that might help them save this bird species from what some ornithologists say is a very likely extinction.
Bird
According to the research team, which included about a dozen participants, the red knot is one of a large number of shorebirds that are in trouble—70% of shorebird species are in decline, according to Lawrence Niles, a participant and the chief biologist at the Conserve Wildlife Foundation. The red knot’s problem is especially acute, though, in that some of its populations have withered by 75% since the 1980s.

4 Legless Lizard Species Discovered in California

Four previously unknown species of snakelike creatures have been found in California — but don't call them snakes; they're legless lizards. Prior to the discovery of the new species, there was only one known legless lizard species in the United States: the California legless lizard.
Legless Lizard
Surprisingly, the newfound legless lizards were discovered at a series of sites that weren't exactly pristine: They include a dune bordering a runway at Los Angeles International Airport; an empty lot in downtown Bakersfield, Calif.; a field littered with oil derricks; and the margins of the Mojave Desert.

Amazonian Butterflies Drink Turtle Tears

The sight of butterflies flocking onto the heads of yellow-spotted river turtles in the western Amazon rain forest is not uncommon, at least if one is able to sneak up on the skittish reptiles. But the reason why butterflies congregate onto the turtles may be stranger than you think: to drink their tears.
Amazonian Butterflies Drink Turtle Tears
The butterflies are likely attracted to the turtles' tears because the liquid drops contain salt, specifically sodium, an important mineral that is scant in the western Amazon, said Phil Torres, a scientist who does much of his research at the Tambopata Research Center in Peru and is associated with Rice University.

Found: The First Mechanical Gear in a Living Creatur

With two diminutive legs locked into a leap-ready position, the tiny jumper bends its body taut like an archer drawing a bow. At the top of its legs, a minuscule pair of gears engage—their strange, shark-fin teeth interlocking cleanly like a zipper. And then, faster than you can blink, think, or see with the naked eye, the entire thing is gone. In 2 milliseconds it has bulleted skyward, accelerating at nearly 400 g's—a rate more than 20 times what a human body can withstand. At top speed the jumper breaks 8 mph—quite a feat considering its body is less than one-tenth of an inch long.
Issus
This miniature marvel is an adolescent issus, a kind of planthopper insect and one of the fastest accelerators in the animal kingdom. As a duo of researchers in the U.K. report today in the journal Science, the issus also the first living creature ever discovered to sport a functioning gear. "Jumping is one of the most rapid and powerful things an animal can do," says Malcolm Burrows, a zoologist at the University of Cambridge and the lead author of the paper, "and that leads to all sorts of crazy specializations."

Ear Wax From Whales Keeps Record Of Ocean Contaminants

How often do whales clean their ears? Well, never. And so, year after year, their ear wax builds up, layer upon layer. According to a study published Monday, these columns of ear wax contain a record of chemical pollution in the oceans.

Infected Monkeys On The Loose In Florida

(WILDLIFE) FLORIDA — It started with three Rhesus monkeys, and now more than a thousand are living freely in the sunshine state. Because many of the animals are infected with the herpes-B virus, wildlife officials are now calling the monkeys a public health hazard—all because a tour guide snatched them from their home and brought them to Ocala, Florida to entertain tourists on his Jungle Cruise ride. Native to Asia, Rhesus monkeys are highly social and easily adapt to many habitats, including Florida. Only now, the little guys are being accused of terrorizing the state—just one more reason why we shouldn’t uproot wildlife for our own amusement.

Dog Houses and Dog House Plans


While the average dog owner would be quick in considering pre-made dog houses as the best dog house options available, there’s actually more to dog houses than the pre-made, easy to set up and ready for occupancy variety.

Custom-made dog houses actually have their own growing line of followers, with such products tailor-cut and specified to fit with the particulars of a given canine, regardless of size, age or breed.


If you happen to be in search for the best dog house for your best friend, don’t turn your back on the upsides of custom dog houses and the importance of dog house plans.

Dog Houses and Dog House Plans

As with any construction project, the making of a custom dog house begins with a dog house plan, a blueprint that’s made around the particulars and specifics of a given canine.

While many would be quick in dismissing the blueprint drafting process involved in the making of custom dog houses, their creation is actually more than just a step-up guide for carpenters and artisans, with their drafting also affording dog owners with essential cost estimates and completion date projections.

A dog house plan also helps dog owners take a firm hold on the type of materials which would be used in their making, giving them the upper hand of being able to pick out what is available from what has to be ordered.

From hardcopy blueprints to digitally rendered plans, a custom dog house need to have its own blueprints and plans for them to be of relevance to dogs and their owners alike.

Choosing the right Cat Carrier


The question that asks “what’s the right cat carrier for my cat?” has been asked by cat owners at one point in time.

If you happen to be among the many wondering what deems a cat carrier the right one for your cat, below are two points worth looking into, in helping you determine which cat carrier option is best for you and your furry feline.


Understanding the need for cat carriers – Picking out the right cat carrier for your cat is not exactly rocket science, requiring only the most minimum understanding of a cat’s personality, as well as understanding what a cat carrier is for.

Unlike dogs, cats tend to be easily content when in confined spaces, making the necessity of getting bigger sized cat carriers subject to how one’s cat reacts to being enclosed, meaning one doesn’t have to get the biggest type of cat carrier case.

Convenience, not just for cats, but owners too – Many have made the mistake of     focusing too much on their cats when in search for cat carriers, failing to consider just what their convenience points for cat owners are.

The aspect of a cat carrier’s “handling” is one good example in this regard, with many cat owners failing to consider if a given case is designed to be easy to bring about, not requiring two persons to carry it around.

Stackability is another consideration, something which cat owners should ask themselves when picking out a cat carrier.

Do well in remembering the above mentioned cat carrier considerations when in search for your cat’s right cat carrier type, and you won’t succumb to getting one that’s more of a problem, rather than a convenience.

The Best Students In The Animal Kingdom


The common chimpanzee is often held up as the most intelligent non-human primate--well, really, the most intelligent non-human animal--on the planet. But that ignores the brilliance of the common chimp's close relative: the bonobo.
bonobo



Kanzi is probably the best-known bonobo in the world; now in her early 30s, Kanzi has exhibited the most linguistic abilities of any bonobo in history. Among her accomplishments are mastering Pac-Man, figuring out that toasting marshmallows over a fire is delicious, learning to communicate with both lexigrams and American Sign Language, and attempting to communicate vocally (although this is mostly incomprehensible, as bonobo vocal cords are very different from our own).

Marine Mammal: Bottlenose Dolphin

No surprise here: the bottlenose dolphin is typically thought of as the most intelligent non-human animal after the chimp and bonobo, and the more research we do, the more impressive dolphins become. They've been known to teach each other games and tricks, like walking on their tails or blowing bubble rings; they can use tools (dolphins off the coast of Australia learned to keep sponges over their noses to protect themselves from spiny but delicious urchins); they've been trained by the navy; they've been proven to understand at least some elements of the concept of numbers. However, it's difficult to measure the dolphin's intelligence due to its capabilities as a mimic. Is it learning, or copying? Who knows?

Cat Carrier Types – Hard Cat Carriers


Everyone knows how popular cats are as pets, with the fact that pet supplies and pet specialty stores are riddled with different pet accessories and grooming kits proves to back this fact.

When talking about pet supplies built specifically for cats, cat carriers are among the most commonly encountered, designed as cases which cat owners can utilize in transporting their felines from point A to point B.


The hard cat carrier variety of cat carriers remains to be one of the cat carrier types, made not just to “store” cats for trips, but also built to afford cats with ample protection from the rough rigors travelling can impose on them.

Hard Cat Carriers – Typically made with plastic and metal wire mesh components, hard cat carriers are generally built to be compact and sturdy carriers for cats.

From stackable cat carriers to dedicated single-item cases, hard cat carriers are typically sized to accommodate adult cats, with some designed with built-in feeding trays. Some are even designed with “indoor” litter boxes, with such spaces “compartmentalized” to suit a cat’s needs.

Generally, hard cat carriers are utilized by cat owners as a means of transporting their pets from the house to trips to the vet, but their use is not only limited for short term trips to certain destinations – at times even used in transporting cats from one city to another.

Often viewed as the general purpose cat carrier, hard cat carriers are essentially practical pet accessories to have handy in the house, useful and functional in securing a cat from external factors when necessary.

Fish: This One Goldfish

Fish are near-impossible to train; their brains work so differently from ours that the typical way you'd train a dog or pig or parrot doesn't really work. But after years of training, one British man managed to train his goldfish to obey certain basic commands, like nudging a small soccer ball into a goal.

Bird: Crow

Crows are noisy, scary-looking bullies, which, in the animal world, usually signals intelligence. The crow is perhaps the best problem-solver of the group, but it's also a very fast learner. In a recent experiment, crows were found to remember and communicate the faces of individual people who were thought of as a threat. By the end of the experiment, the person who had wronged one crow found himself the enemy of all crows on campus--even though he had interacted with hardly any of them.

Livestock: Pig


Of the most common livestock animals, bred into domesticity for milk or meat or fur, the pig is easily the fastest learner. The pig doesn't pass the famous mirror self-awareness test, but it can use the mirror to find the location of food that's out of sight--which might just mean the pig cares more about food than its own reflection.

pigs

Yet pigs are also incredibly quick learners, perhaps the fastest in the entire animal kingdom. From the NYTimes:

"They’ve found that pigs are among the quickest of animals to learn a new routine, and pigs can do a circus’s worth of tricks: jump hoops, bow and stand, spin and make wordlike sounds on command, roll out rugs, herd sheep, close and open cages, play videogames with joysticks, and more."

Cat: Abyssinian


Intelligence is hard or impossible to measure in most animals, but especially difficult to measure in felines, which are not pack animals and so have little interest in social hierarchies--which means they don't pay much attention to commands from us. Dogs, on the other hand, have instincts to obey the alpha in their pack--which is often a human. Cats just don't think this way. But the Abyssinian, one of the oldest known breeds of cat, is noted by much of the cat fancy community as the smartest breed.
Abyssinian
Abyssinians can't be trained, exactly, but they will exhibit signs of learning. They can be taught to play fetch--perhaps the only breed of cat that will do this reliably. No studies have been performed to measure the Abyssinian's intelligence, but anecdotal evidence suggests the Abyssinian is energetic and curious, able to figure out small puzzles (like doorknobs) quickly.
