Safety And Strength of Centaur Horse Fence

gmhfmHorse fences should be generally very strong as the animals are very health and possess good strength to break any of the minor fences and get out. There are varieties of fences available in the market among which you can choose the one that will suite your requirement. The centaur Hestehegn will be an ideal way to keep your horses within the area and protect them from other invaders. If you are choosing the centaur horse fences, you will be ideally choosing one of the most flexible and strongest horse fences. Not only the fence category rather your budget will be another important factor which should be considered while choosing the fence.

Advantages of centaur horse fence

People installing this particular variety of horse fence will ideally proceed with variety of its benefits. The manufacturers say that it is a time tested variety of Hestehegn which can be believed by closing your eyes. Since the material with which the horse fence is made is of a heavy weight polymer, it will certainly add value to the protective variation. Your horse will be really very safe within these

Why are some wild animals more tolerant to human interaction than others

fsjtyskWhen most wild animals first encounter humans, they respond as they would to any predator — by running, swimming or flying away.

Over time, some species become more tolerant of humans’ presence, but the extent to which they do is largely driven by the type of environment in which the animals live and by the animal’s body size, according to a comprehensive new analysis.

Researchers led by Daniel Blumstein, a professor and chair of ecology and evolutionary biology in the UCLA College, analyzed 75 studies conducted over the past half-century of 212 animal species — mostly birds, but also mammals and lizards. The scientists estimated species’ tolerance to human disturbance by comparing how far away from humans an animal would have to be before it fled — a statistic called ‘flight initiation distance.’

The paper was published in Nature Communications. Among the findings:

  • Birds in more heavily populated urban areas are much more tolerant of humans than birds in rural areas.
  • Larger birds are more tolerant of humans than smaller birds.

Although Blumstein said the first finding was to be expected, he

Pets may help reduce your risk of heart disease

gfjtrhsHaving a pet might lower your risk of heart disease, according to a new American Heart Association scientific statement.

The statement is published online in the association’s journal Circulation.

“Pet ownership, particularly dog ownership, is probably associated with a decreased risk of heart disease,” said Glenn N. Levine, M.D., professor at Baylor College of Medicine in Houston, Texas, and chair of the committee that wrote the statement after reviewing previous studies of the influence of pets.

Research shows that:

  • Pet ownership is probably associated with a reduction in heart disease risk factors and increased survival among patients. But the studies aren’t definitive and do not necessarily prove that owning a pet directly causes a reduction in heart disease risk. “It may be simply that healthier people are the ones that have pets, not that having a pet actually leads to or causes reduction in cardiovascular risk,” Levine said.
  • Dog ownership in particular may help reduce cardiovascular risk. People with dogs may engage in more physical activity because they walk them. In a study of more than 5,200 adults, dog owners engaged in more

Strolling salamanders provide clues on how animals evolved to move from water to land

Around 390 million years ago, the first vertebrate animals moved from water onto land, necessitating changes in their musculoskeletal systems to permit a terrestrial life. Forelimbs and hind limbs of the first tetrapods evolved to support more weight. But what specific mechanisms drove changes in bone function?

The tiger salamander might provide some clues. A new study from a team of scientists from the National Institute for Mathematical and Biological Synthesis (NIMBioS) and Clemson University evaluates what mechanisms drive diversity in bone function, providing new insight into the evolution of how tetrapods–the earliest four-legged vertebrate animals–took their first steps on land.

In order to understand the biology of fossilized animals, researchers often turn to living animals with similarities that help model how extinct animals moved. Salamanders are particularly good organisms for studying how locomotion onto land evolved, as their anatomy and ecology is similar to the earliest tetrapods.

Bones must regularly withstand a variety of different forces, or “loads,” from both the contraction of muscles and from interaction with the environment. Limb bones in particular must accommodate some of the highest forces. Fossil records suggest that the forelimb and hind limb may

An arms race among venomous animals

In a new study published in the journal PLOS Genetics, scientists at the Hebrew University of Jerusalem have revealed new discoveries about how animal venom evolves. The research points to a ‘two-speed’ evolution of animal venom, showing for the first time the significant roles played by different forces of natural selection.

Venom is a complex mixture of proteins and other toxic chemicals produced by animals such as snakes and spiders, either to incapacitate their prey or to defend against predators. The influence of positive selection (the process by which a protein changes rapidly over evolutionary time scales) in expanding and diversifying animal venoms is widely recognized.

This process was hypothesized to result from an evolutionary chemical arms race, in which the invention of potent venom in the predatory animals and the evolution of venom resistance in their prey animals, exert reciprocal selection pressures.

In contrast to positive selection, the role of purifying selection (also known as negative selection, which is the selective removal of deleterious genetic changes from a population) has rarely been considered in venom evolution.

Moreover, venom research has mostly neglected ancient animal groups in favor of focusing on

Declines in whales, fish, seabirds and large animals disrupt Earth’s nutrient cycle

Giants once roamed the earth. Oceans teemed with ninety-foot-long whales. Huge land animals–like truck-sized sloths and ten-ton mammoths–ate vast quantities of food, and, yes, deposited vast quantities of poop.

A new study shows that these whales and outsized land mammals–as well as seabirds and migrating fish–played a vital role in keeping the planet fertile by transporting nutrients from ocean depths and spreading them across seas, up rivers, and deep inland, even to mountaintops.

However, massive declines and extinctions of many of these animals has deeply damaged this planetary nutrient recycling system, a team of scientists reported October 26 in the Proceedings of the National Academy of Sciences.

“This broken global cycle may weaken ecosystem health, fisheries, and agriculture,” says Joe Roman, a biologist at the University of Vermont and co-author on the new study.

On land, the capacity of animals to carry nutrients away from concentrated “hotspots,” the team writes, has plummeted to eight percent of what it was in the past–before the extinction of some 150 species of mammal “megafauna” at the end of the last ice age.

And, largely because of human hunting over the last few centuries,

Would you eat your pet cat

In most Western cultures cats are simply feline pet companions eager to greet us at the end of the day. In continents such as Asia and Africa, the social norms surrounding cats are very different; our furry friends commonly double up as dinner for a number of reasons ranging from food insecurity, simple preference or superstition. It is estimated that 4 million cats are consumed annually in Asia alone. Raymond Czaja et al recently conducted research on cat consumption in Anthrozoös. Their study reveals motives for, prevalence and methods of cat consumption in Madagascar and resulting public health implications for Malagasy citizens and beyond.

Cats and humans have interactions dating back 8,000 years. From ancient civilization until today they have served many and varied roles; deity, devil, pest controller, status symbol and straight forward household pet. Cat consumption though known is little understood, Czaja et al set out to illuminate causes and practices of eating cats in Madagascar. This Indian Ocean Island has weathered a HIV epidemic, a coup d’état and widespread economic instability within the last decade. Nevertheless the population steadily rises and malnutrition and poverty are rife. Cats are widespread across Madagascar
