Dog Ownership May Improve Your Health

A Swedish publication released recently says that having a dog could not only make your life more worthwhile but actually save it. Apart from being great companions, especially for single individuals, dog ownership may lengthen your life. The survey studied Swedish individuals between 40 and 80 over a 12-year period.

The study found out that owning a dog reduces the risk of cardiovascular diseases by almost a third. The risk of suffering a heart attack is 11% lower compared to singles without a dog. People who owned hunting dogs, like terriers and retrievers, benefited the most.

Dog owners are more active because they exercise with their dogs. Extensive physical activity reduces the risk of heart diseases, strengthens the immune system and makes life less stressful. It also results in lower blood pressure and cholesterol levels.

Dogs are increasingly used as a therapy after a severe illness. An American study shows that patients who have undergone surgery recovered more quickly if they had contact with dogs.

On the other side dogs have a calming effect on people and are important company for those living alone. Loneliness and lack of social interaction is one of the biggest problems of older people. Petting a dog, for example, has proven to be helpful to those suffering from depression. In addition, dogs are especially helpful in helping and guiding disabled and blind people.

Behaviour of Whales and Dolphins Connected to Brain Size

Scientists have found out that the behaviour of marine mammals, especially dolphins and whales, is connected to their brain  size . In a recent study, researchers have found out that mammals with larger brains behave in a more complex way.

Researchers have collected information on about 90 different types of dolphins and whales. They found out that social behaviour among these two  species is more complex  than previously thought.

Whales, for example, change calling songs regularly and pass certain information on to their younger ones and other groups. They use various languages which are similar to human dialects. Sperm whales, with a brain six times the size of a human one, organise other whales to babysit for them while they go hunting for food.

Other whale species, like blue or humpback whales, have smaller brains. They live in a more solitary way and don’t have long-term relationships.

Dolphins have a way of contacting  other individuals , even if they are not present. Scientists regard this as a form of gossip. As well as having rich and varied diets, they play and hunt  together.

Scientists think that bigger brains have evolved in order handle the complex way that mammals socialise.

Thousands of Penguin Babies Die in the Antarctic

Thousands of penguin babies have starved to death in the eastern Antarctic recently . Observers found thousands of unhatched eggs and lifeless baby penguins  on the coast. According to scientists , only two baby penguins survived during the 2017 breeding seasonAdélie penguins live in colonies that consist of thousands of animals.  It is the second time that a whole colony has been wiped out after no babies survived in 2015.

The World Wildlife Fund says that krill fishing in the area has led to the starving of penguin babies. Officials state that fishing in the area may permanently endanger the whole penguin population in the Antarctic.

Another reason for the declining number of Adélie penguins is possibly climate change.  In regions where ice gets thicker, adult penguins must  travel further away from the shore in order to find food. When they get back they find many of their babies already dead.

The WWF  and other organisations now demand that the eastern Antarctic coastline be declared a Marine Protected Area in order to help endangered penguins. Commercial fishing should be banned around these areas .

Adélie penguins live along the Antarctic coast  and usually breed from October to February.  They lay eggs in nests made up of stones.

Largest and Smallest Animals At Risk of Becoming Extinct

Researchers have found out that the size of an animal is important when it comes to extinction. Scientists have determined that the biggest and the smallest animals are more at risk of dying out than medium-sized animals.

Heavy animals are mostly endangered by hunting and poaching while the smallest creatures may die out because their living area is being polluted. Among the most endangered animals are elephants, lions and rhinos. Public awareness is large  and campaigns to save such animals have been around for a long time. It is the smallest species that get the least attention. Especially fish and frogs are in danger of dying out.

The species that are most at risk have a weight of over 1 kilogram. They are in danger of being killed because we need food, skin and other items.

According to the study, animals that are becoming extinct affect large ecosystems, like  forests, deserts and oceans.
