Pest plants and animals cost Australia around $25bn a year – and it’s going to get worse

Unfortunately, Australia has one of the highest extinction rates in the world. And the number one threat to our species is invasive or “alien” plants and animals. But invasive species not only cause extinctions and loss of biodiversity, they also create a heavy economic burden. Our to research, published today, reveals that invasive species have […]

The fires ravaged not only plants and animals, but the soil beneath them

Over 80 percent of the Great Blue Mountains World Heritage area, including much of the watershed around the Warragamba Dam.Credit:James brickwood A separate study showed that the Warrambungle fire in 2013 resulted in annual soil losses of about 25 tonnes per hectare, which matches the government’s projected national park losses of 19.4 tonnes per hectare […]

Researcher focuses on restoring disturbed ecosystems

Bob Shriver, assistant professor in the Department of Natural Resources and Environmental Sciences, focuses his teaching and research on understanding and predicting how local plant population demographics, such as survival and growth, respond to climate, disturbance and human management. As part of the College of Agriculture, Biotechnology & Natural Resources, Shriver’s work centers on restoration […]

Goldfish Thrown Into Lakes Reaching Over 1 Foot, Threatening Ecosystems | Invasive species

Minnesota authorities have called on aquarium owners to stop releasing pet fish into waterways, after several huge goldfish were pulled from a local lake. Officials in Burnsville, about 15 miles south of Minneapolis, said released goldfish can grow several times their normal size and wreak havoc on native species. “Please don’t release your goldfish into […]

How to Avoid Harming New Zealand’s Various Native Plants and Animals

Credit: Snappy Goat/Flickr New Zealand’s native biodiversity is unique and complex, and it is in decline and under threat. Individuals and businesses are often unsure of what they should or should not do to help maintain it. A new paper in the New Zealand Journal of Ecology sets out comprehensive and concise criteria to provide […]

Silk Road also brought plants and animals

The Ancient Silk Road was an important route for transporting Chinese silk, tea, and porcelain to other countries around 2,000 years ago. An abundance of animals and plants were also introduced from the West, enriching the lives of the Chinese people in ancient times. Foreign envoys brought their local animals and plants as gifts to […]

Leading Scientists Support Need To Consider Biomechanics – ScienceDaily

A team of scientists have developed a more accurate way to predict the effects of climate change on plants and animals, and whether some will survive. Frequently, environmentalists assess an organism’s fitness for climate by quantifying its functional traits. “These are physical properties that you can measure – the height, the diameter, the thickness of […]

Better predict how plants and animals

By understanding the variables that help resist these forces, as well as air or water speeds, scientists can use an ecomechanical model to make predictions about survival. see Following Credit: (Tim Higham / UCR) A […]
