When Leopard seals can’t eat their own offspring

National Geographic – The life history of the leopard seal is not the same as that of a cat.

In fact, they’re quite different animals.

But that’s what the scientists who have studied them for more than 50 years have learned.

In their new book Leopard Seal Size and Life History, published this month by National Geographic, they report that leopard seals live in different ecological niches than do cats, and they have much in common with the great white shark.

They are also far more similar to their larger cousins than to the great brown seal, the largest of the marine mammals.

The difference is that, in terms of their diet, leopard sharks and great white sharks eat mostly fish and crustaceans, while the seals eat mostly marine mammals and birds.

In addition to its long and storied history of research, National Geographic also highlights the important role that the seal plays in our own ecosystems.

“As the seal population in the Arctic continues to decline due to climate change and overfishing, and the global economy continues to shrink, our understanding of its evolutionary history and potential roles in our ecosystem is vital to understanding the impacts of climate change on the ocean and on human health,” the magazine says.

Australia’s first new concrete sealer in 10 years is ready to go, says government

Posted August 23, 2018 06:22:17 A new cement sealer is finally in the works in Australia and its being hailed as a boon for the environment, the economy and for local communities.

Key points:The new concrete-based sealer will be rolled out in Queensland and New South Wales, and will be used to create concrete walls around dams and other infrastructureNew cement seals will be required to seal in rivers and coastal waterwaysThe project will use a mix of marine and cement to make the new concrete wall The project, which is expected to be completed by early 2019, is the first of its kind in Australia, and has been designed by the Queensland Government’s Environment Protection and Research Agency (EPARA).

Key pointsThe project, by EPARA, will use marine cement and concrete to make a concrete wall to protect the country’s dam systemsThe new sealer, which will be made in Queensland, is designed to help keep rivers and other dams at bayNew concrete seals will also be required for waterwaysThe new cement seals are designed to be permanent, meaning that they will be able to keep rivers from overflowing and keep coastal waterways at bay, Environment Minister Stuart Robert said.

“We are looking at a project that will be very durable and very strong,” he said.

Mr Robert said the project was expected to create an extra $2.2 billion for the Queensland economy.

“In the long run it’s a very big and positive investment for the state,” he added.

The concrete wall project will be completed in Queensland by early next year and will cover more than 400 kilometres (250 miles) of the Great Barrier Reef.

“This will be the largest concrete wall we’ve ever seen and it’s going to be able and willing to do its job,” Mr Robert said, referring to the huge concrete wall used to keep flood waters at bay in Sydney.

“The water is not going to just rush over it and there’s no risk to the environment.”

The new seals will make up a mixture of marine cement, cement-derived marine resins, and marine cement derived from a mix with marine resin that was used to make cement in Queensland.

The project was developed by the EPARAs Queensland and NSW division, which was contracted to the Government by the Australian Construction Association (ACT).

The Queensland Government has already announced a commitment to the project, with a $2 million grant for the first five years, which the EPARA said would be used for the design and construction of the cement wall.

“Once it is in place, it will be ready for use in the next five years,” Mr Robinson said.

The state Government will also receive a $1 million grant to develop the project.

“They’re not going up against any of the major international companies, and this is a new project that has been created in Queensland,” Mr Roberts said.

He said the Government was still in talks with the private sector and construction firms about how the project would be funded.

“So the State Government is keen to see what the private and private sector have to say, but we have to work out how we’re going to pay for it,” he told ABC Radio Brisbane.

“There’s a big commitment to be made here, but the State has to be looking at all the options and making sure that the money is being spent properly and the environmental benefits are being recognised.”
